Background Hepatitis B vaccination is recommended for persons with current or past sexually transmitted infections (STI). Our aim is to systematically assess the association of hepatitis B virus (HBV) sero-markers for current or past infection with syphilis, chlamydia, gonorrhoea, or unspecified STIs. Methods: We conducted a systematic review and meta-analysis. PubMed, Embase, and Web of Science from 1982 to 2018 were searched using medical subject headings (MeSH) terms for HBV, STIs and epidemiology. We included studies conducted in Organisation for Economic Cooperation and Development countries or Latin America that permit the calculation of prevalence ratios (PRs) for HBV and STIs and extracted PRs and counts by HBV and STI status. Results: Of 3144 identified studies, 43 met inclusion requirements, yielding 72 PRs. We stratified outcomes by HBV sero-markers [surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), combined], STI pathogen (syphilis, gonorrhoea/chlamydia, unspecified), and STI history (current, past) resulting in 18 potential outcome groups, for which results were available for 14. For the four outcome groups related to HBsAg, PR point estimates ranged from 1.65 to 6.76. For the five outcome groups related to anti-HBc, PRs ranged from 1.30 to 1.82; and for the five outcome groups related to combined HBV markers, PRs ranged from 1.15 to 1.89). The median HBsAg prevalence among people with a current or past STI was 4.17; not all studies reported HBsAg. Study settings and populations varied. Conclusion: This review found evidence of association between HBV infection and current or past STIs.

BackgroundFemur fracture patients require significant in-hospital care. The burden incurred by caregivers of such patients amplifies the direct costs of these injuries and remains unquantified. Aim Here we aim to establish the in-hospital economic burden faced by informal caregivers of femur fracture patients. Methods 70 unique caregivers for 46 femoral shaft fracture patients were interviewed. Incurred economic burden was determined by the Human Capital Approach, using standardized income data to quantify productivity loss (in $USD). Linear regression assessed the relationship between caregiver burden and patient time-in-hospital.ResultsThe average economic burden incurred was $149, 9% of a caregiver’s annual income and positively correlated with patient time in hospital (p

Intensive psychotherapy assisted with 3,4-methylenedioxymethamphetamine (MDMA-AT) was shown in Phase 3 clinical trials to substantially reduce post-traumatic stress disorder (PTSD) symptoms compared to psychotherapy with placebo. This study estimates potential costs, health benefits, and net savings of expanding access to MDMA-AT to eligible US patients with chronic and severe PTSD.Using a decision-analytic model, we compared the costs, deaths averted, and quality-adjusted life years (QALYs) gained of three, 10-year MDMA-AT coverage targets (25%, 50%, and 75%) compared to providing standard of care to the same number of eligible patients with chronic and severe PTSD. We used a payer perspective and discounted costs (in US$) and QALYs to 2020. We conducted one-way, scenario, and probabilistic sensitivity analyses and calculated the net monetary value of MDMA-AT using a cost-effectiveness threshold of $100,000 per QALY gained.Expanding access to MDMA-AT to 25-75% of eligible patients is projected to avert 43,618-106,932 deaths and gain 3.3-8.2 million QALYs. All three treatment targets are dominant or cost-saving compared to standard of care. Our sensitivity analyses found that accounting for parameter uncertainty and changes in various assumptions did not alter the main finding-MDMA-AT is dominant compared to standard of care.Expanding access to MDMA-AT to patients with chronic and severe PTSD will provide substantial health and financial benefits. The precise magnitude is uncertain and will depend on the number of eligible patients and other inputs.

Background Surgical disease increasingly contributes to global mortality and morbidity. The Lancet Commission on Global Surgery found that global cost-effectiveness data are lacking for a wide range of essential surgical procedures. This study helps to address this gap by defining the cost-effectiveness of exploratory laparotomies in a regional referral hospital in Uganda. Materials and methods A time-and-motion analysis was utilized to calculate operating theater personnel costs per case. Ward personnel, administrative, medication, and supply costs were recorded and calculated using a microcosting approach. The cost in 2018 US Dollars (USD, $) per disability-adjusted life year (DALY) averted was calculated based on age-specific life expectancies for otherwise fatal cases. Results Data for 103 surgical patients requiring exploratory laparotomy at the Soroti Regional Referral Hospital were collected over 8 mo. The most common cause for laparotomy was small bowel obstruction (32% of total cases). The average cost per patient was $75.50. The postoperative mortality was 11.7%, and 7.8% of patients had complications. The average number of DALYs averted per patient was 18.51. The cost in USD per DALY averted was $4.08. Conclusions This investigation provides evidence that exploratory laparotomy is cost-effective compared with other public health interventions. Relative cost-effectiveness includes a comparison with bed nets for malaria prevention ($6.48-22.04/DALY averted), tuberculosis, tetanus, measles, and polio vaccines ($12.96-25.93/DALY averted), and HIV treatment with multidrug antiretroviral therapy ($453.74-648.20/DALY averted). Given that the total burden of surgically treatable conditions in DALYs is more than that of malaria, tuberculosis, and HIV combined, our findings strengthen the argument for greater investment in primary surgical capacity in low- and middle-income countries.

The past decade has seen a growing emphasis on the production of high-quality costing data to improve the efficiency and cost-effectiveness of global health interventions. The need for such data is especially important for decision making and priority setting across HIV services from prevention and testing to treatment and care. To help address this critical need, the Global Health Cost Consortium was created in 2016, in part to conduct a systematic search and screening of the costing literature for HIV and TB interventions in low- and middle-income countries (LMIC). The purpose of this portion of the remit was to compile, standardise, and make publicly available published cost data (peer-reviewed and gray) for public use. We limit our analysis to a review of the quantity and characteristics of published cost data from HIV interventions in sub-Saharan Africa. First, we document the production of cost data over 25 years, including density over time, geography, publication venue, authorship and type of intervention. Second, we explore key methods and reporting for characteristics including urbanicity, platform type, ownership and scale. Although the volume of HIV costing data has increased substantially on the continent, cost reporting is lacking across several dimensions. We find a dearth of cost estimates from HIV interventions in west Africa, as well as inconsistent reporting of key dimensions of cost including platform type, ownership and urbanicity. Further, we find clear evidence of a need for renewed focus on the consistent reporting of scale by authors of costing and cost-effectiveness analyses.Keywords: costing, HIV/AIDS, LMIC, cost-effectiveness, systematic review

Consistently defined, accurate, and easily accessible cost data are a valuable resource to inform efficiency analyses, budget preparation, and sustainability planning in global health. The Global Health Cost Consortium (GHCC) designed the Unit Cost Study Repository (UCSR) to be a resource for standardised HIV and TB intervention cost data displayed by key characteristics such as intervention type, country, and target population. To develop the UCSR, the GHCC defined a typology of interventions for each disease; aligned interventions according to the standardised principles, methods, and cost and activity categories from the GHCC Reference Case for Estimating the Costs of Global Health Services and Interventions; completed a systematic literature review; conducted extensive data extraction; performed quality assurance; grappled with complex methodological issues such as the proper approach to the inflation and conversion of costs; developed and implemented a study quality rating system; and designed a web-based user interface that flexibly displays large amounts of data in a user-friendly way. Key lessons learned from the extraction process include the importance of assessing the multiple uses of extracted data; the critical role of standardising definitions (particularly units of measurement); using appropriate classifications of interventions and components of costs; the efficiency derived from programming data checks; and the necessity of extraction quality monitoring by senior analysts. For the web interface, lessons were: understanding the target audiences, including consulting them regarding critical characteristics; designing the display of data in “levels”; and incorporating alert and unique trait descriptions to further clarify differences in the data.Keywords: tuberculosis, database, reference case, systematic review

Objective: To estimate facility-level average cost for ART services and explore unit cost variations using pooled facility-level cost estimates from four HIV empirical cost studies conducted in five African countries .Methods: Through a literature search we identified studies reporting facility-level costs for ART programmes. We requested the underlying data and standardised the disparate data sources to make them comparable. Subsequently, we estimated the annual cost per patient served and assessed the cost variation among facilities and other service delivery characteristics using descriptive statistics and meta-analysis. All costs were converted to 2017 US dollars ($).Results: We obtained and standardised data from four studies across five African countries and 139 facilities. The weighted average cost per patient on ART was $251 (95% CI: 193–308). On average, 46% of the mean unit cost correspond to antiretroviral (ARVs) costs, 31% to personnel costs, 20% other recurrent costs, and 2% to capital costs. We observed a lot of variation in unit cost and scale levels between countries. We also observed a negative relationship between ART unit cost and the number of patients served in a year.Conclusion: Our approach allowed us to explore unit cost variation across contexts by pooling ART costs from multiple sources. Our research provides an example of how to estimate costs based on heterogeneous sources reconciling methodological differences across studies and contributes by giving an example on how to estimate costs based on heterogeneous sources of data. Also, our study provides additional information on costs for funders, policy-makers, and decision-makers in the process of designing or scaling-up HIV interventions.Keywords: HIV, treatment, efficiency, cost variatio

Background The US National HIV/AIDS Strategy (NHAS) emphasizes the use of technology to facilitate coordination of comprehensive care for people with HIV. We examined cost-effectiveness from the health system perspective of 6 health information technology (HIT) interventions implemented during 2008 to 2012 in a Ryan White HIV/AIDS Program (RWHAP) Special Projects of National Significance (SPNS) Program demonstration project. Methods/findings HIT interventions were implemented at 6 sites: Bronx, New York; Durham, North Carolina; Long Beach, California; New Orleans, Louisiana; New York, New York (2 sites); and Paterson, New Jersey. These interventions included: (1) use of HIV surveillance data to identify out-of-care individuals; (2) extension of access to electronic health records (EHRs) to support service providers; (3) use of electronic laboratory ordering and prescribing; and (4) development of a patient portal. We employed standard microcosting techniques to estimate costs (in 2018 US dollars) associated with intervention implementation. Data from a sample of electronic patient records from each demonstration site were analyzed to compare prescription of antiretroviral therapy (ART), CD4 cell counts, and suppression of viral load, before and after implementation of interventions. Markov models were used to estimate additional healthcare costs and quality-adjusted life-years saved as a result of each intervention. Overall, demonstration site interventions cost $3,913,313 (range = $287,682 to $998,201) among 3,110 individuals (range = 258 to 1,181) over 3 years. Changes in the proportion of patients prescribed ART ranged from a decrease from 87.0% to 72.7% at Site 4 to an increase from 74.6% to 94.2% at Site 6; changes in the proportion of patients with 0 to 200 CD4 cells/mm3 ranged from a decrease from 20.2% to 11.0% in Site 6 to an increase from 16.7% to 30.2% in Site 2; and changes in the proportion of patients with undetectable viral load ranged from a decrease from 84.6% to 46.0% in Site 1 to an increase from 67.0% to 69.9% in Site 5. Four of the 6 interventions—including use of HIV surveillance data to identify out-of-care individuals, use of electronic laboratory ordering and prescribing, and development of a patient portal—were not only cost-effective but also cost saving ($6.87 to $14.91 saved per dollar invested). In contrast, the 2 interventions that extended access to EHRs to support service providers were not effective and, therefore, not cost-effective. Most interventions remained either cost-saving or not cost-effective under all sensitivity analysis scenarios. The intervention that used HIV surveillance data to identify out-of-care individuals was no longer cost-saving when the effect of HIV on an individual’s health status was reduced and when the natural progression of HIV was increased. The results of this study are limited in that we did not have contemporaneous controls for each intervention; thus, we are only able to assess sites against themselves at baseline and not against standard of care during the same time period. Conclusions These results provide additional support for the use of HIT as a tool to enhance rapid and effective treatment of HIV to achieve sustained viral suppression. HIT has the potential to increase utilization of services, improve health outcomes, and reduce subsequent transmission of HIV., Starley Shade and co-workers assess cost-effectiveness of information technology interventions in HIV care programs in the United States., Author summary Why was this study done? The Health Resources and Services Administration’s Special Projects of National Significance Program (HRSA/SPNS) funded a 4-year initiative (2007 to 2011) in 6 demonstration sites to enhance and evaluate existing health information electronic network systems for people living with HIV (PLHIV) in underserved communities. Each of the 6 demonstration sites implemented one or more health information technology (HIT) interventions to facilitate comprehensive care and enhance engagement in HIV medical services. These interventions included: (1) use of HIV surveillance data to identify out-of-care individuals; (2) extension of access to electronic health records to support service providers; (3) use of electronic laboratory ordering and prescribing; and (4) development of a patient portal. This study estimates the total costs, cost-effectiveness, and potential cost-savings of these 6 interventions. What did researchers do and find? We used information on the cost of each intervention and the health status of PLHIV in each setting before and after implementation of each intervention to estimate: (1) changes in the cost of care and other services for PLHIV in each setting; and (2) changes in expected health status (measured as quality-adjusted life-years or QALYs) among PLHIV in each setting. We then used this information to estimate additional healthcare costs and QALYs gained for each intervention. Four of the interventions were associated with lower healthcare costs and better health outcomes (QALYs gained) for PLHIV in each setting. These interventions saved between $6.87 and $14.91 per dollar invested. Two interventions that provided access to medical record information to support service providers were not associated with improved health outcomes for PLHIV in these settings. These interventions were not effective or cost-effective. What do these findings mean? These results show that HIT interventions that facilitate changes in patient or provider behavior have the potential to improve the health status of PLHIV and reduce healthcare costs. HIT interventions that only provided additional information to support service providers were less successful. This study did not include a contemporaneous comparison group. Therefore, we do not know the degree to which improvements in the health status of PLHIV in these settings were due to changes in the quality of care for PLHIV over the life of the interventions.

Background Severe posttraumatic stress disorder (PTSD) is a prevalent and debilitating condition in the United States. and globally. Using pooled efficacy data from six phase 2 trials, therapy using 3,4-methylenedioxymethamphetamine (MDMA) appeared cost-saving from a payer’s perspective. This study updates the cost-effectiveness analysis of this novel therapy using data from a new phase 3 trial, including the incremental cost-effectiveness of the more intensive phase 3 regimen compared with the shorter phase 2 regimen. Methods We adapted a previously-published Markov model to portray the costs and health benefits of providing MDMA-assisted therapy (MDMA-AT) to patients with chronic, severe, or extreme PTSD in a recent phase 3 trial, compared with standard care. Inputs were based on trial results and published literature. The trial treated 90 patients with a clinician administered PTSD scale (CAPS-5) total severity score of 35 or greater at baseline, and duration of PTSD symptoms of 6 months or longer. The primary outcome was assessed 8 weeks after the final experimental session. Patients received three 90-minute preparatory psychotherapy sessions, three 8-hour active MDMA or placebo sessions, and nine 90-minute integrative psychotherapy sessions. Our model calculates the per-patient cost of MDMA-AT, net all-cause medical costs, mortality, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). We reported results from the U.S. health care payer’s perspective for multiple analytic time horizons, (base-case is 30 years), and conducted extensive sensitivity analyses. Costs and QALYs were discounted by 3% annually. Costs were adjusted to 2020 U.S. dollars according to the medical component of the U.S. Bureau of Labor Statistics’ Consumer Price Index (CPI). Results MDMA-AT as conducted in the phase 3 trial costs $11,537 per patient. Compared to standard of care for 1,000 patients, MDMA-AT generates discounted net health care savings of $132.9 million over 30 years, accruing 4,856 QALYs, and averting 61.4 premature deaths. MDMA-AT breaks even on cost at 3.8 years while delivering 887 QALYs. A third MDMA session generates additional medical savings and health benefits compared with a two-session regimen. Hypothetically assuming no savings in health care costs, MDMA-AT has an ICER of $2,384 per QALY gained. Conclusions MDMA-AT provided to patients with severe or extreme chronic PTSD is cost-saving from a payer’s perspective, while delivering substantial clinical benefit.

We systematically reviewed the literature to assess the effectiveness of school-based programs to prevent HIV and other sexually transmitted infections (STI) among adolescents in the USA. We searched six databases including PubMed for studies published through May 2017. Eligible studies included youth ages 10-19 years and assessed any school-based programs in the USA that reported changes in HIV/STI incidence or testing. We used Cochrane tool to assess the risk of bias and GRADE to determine the evidence quality for each outcome. Three RCTs and six non-RCTs, describing seven interventions, met study inclusion criteria. No study reported changes in HIV incidence or prevalence. One comprehensive intervention, assessed in a non-RCT and delivered to pre-teens, reduced STI incidence into adulthood (RR 0.36, 95% CI 0.23-0.56). A non-RCT examining chlamydia and gonorrhea incidence before and after a condom availability program found a significant effect at the city level among young men 3 years later (RR 0.43, 95% CI 0.23-0.80). The remaining four interventions found no effect. The effect on STI prevalence was also not significant (pooled RR 0.83 from two non-RCTs, RR 0.70 from one RCT). Only one non-RCT showed an increase in HIV testing (RR 3.19, 95% CI 1.24-8.24). The quality of evidence for all outcomes was very low. Studies, including the RCTs, were of low methodological quality and had mixed findings, thus offering no persuasive evidence for the effectiveness of school-based programs. The most effective intervention spanned 6 years, was a social development-based intervention with multiple components, rather than a sex education program, and started in first grade.

BackgroundChronic posttraumatic stress disorder (PTSD) is a disabling condition that generates considerable morbidity, mortality, and both medical and indirect social costs. Treatment options are limited. A novel therapy using 3,4-methylenedioxymethamphetamine (MDMA) has shown efficacy in six phase 2 trials. Its cost-effectiveness is unknown.Methods and findingsTo assess the cost-effectiveness of MDMA-assisted psychotherapy (MAP) from the health care payer's perspective, we constructed a decision-analytic Markov model to portray the costs and health benefits of treating patients with chronic, severe, or extreme, treatment-resistant PTSD with MAP. In six double-blind phase 2 trials, MAP consisted of a mean of 2.5 90-minute trauma-focused psychotherapy sessions before two 8-hour sessions with MDMA (mean dose of 125 mg), followed by a mean of 3.5 integration sessions for each active session. The control group received an inactive placebo or 25-40 mg. of MDMA, and otherwise followed the same regimen. Our model calculates net medical costs, mortality, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios. Efficacy was based on the pooled results of six randomized controlled phase 2 trials with 105 subjects; and a four-year follow-up of 19 subjects. Other inputs were based on published literature and on assumptions when data were unavailable. We modeled results over a 30-year analytic horizon and conducted extensive sensitivity analyses. Our model calculates expected medical costs, mortality, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio. Future costs and QALYs were discounted at 3% per year. For 1,000 individuals, MAP generates discounted net savings of $103.2 million over 30 years while accruing 5,553 discounted QALYs, compared to continued standard of care. MAP breaks even on cost at 3.1 years while delivering 918 QALYs. Making the conservative assumption that benefits cease after one year, MAP would accrue net costs of $7.6 million while generating 288 QALYS, or $26,427 per QALY gained.ConclusionMAP provided to patients with severe or extreme, chronic PTSD appears to be cost-saving while delivering substantial clinical benefit. Third-party payers are likely to save money within three years by covering this form of therapy.

Femoral shaft fractures are one of the most common injuries seen by surgeons in low- and middle-income countries (LMICs). Surgical repair in LMICs is often dismissed as not being cost-effective or unsafe, though little evidence exists to support this notion. Therefore, the goal of this study is to determine the cost of intramedullary nailing of femoral shaft fractures in Tanzania. We used micro-costing methods to estimate the fixed and variable costs of intramedullary nailing of femoral shaft fractures. Variable costs assessed included medical personnel costs, ward personnel costs, implants, medications, and single-use supplies. Fixed costs included costs for surgical instruments and administrative and ancillary staff. 46 adult femoral shaft fracture patients admitted to Muhimbili Orthopaedic Institute between June and September 2014 were enrolled and treated with intramedullary fixation. The total cost per patient was $530.87 (SD $129.99). The mean variable cost per patient was $419.87 (SD $129.99), the largest portion coming from ward personnel $144.47 (SD $123.30), followed by implant $134.10 (SD $15.00) medical personnel $106.86 (SD $28.18), and medications/supplies $30.05 (SD $12.28). The mean fixed cost per patient was $111.00, consisting of support staff, $103.50, and surgical instruments, $7.50. Our study provides empirical information on the variable and fixed costs of intramedullary nailing of femoral shaft fractures in LMICs. Importantly, the lack of surgical capacity was the primary driver of the largest cost for this procedure, preoperative ward personnel time. Our results provide the cost data for a formal cost-effectiveness analysis on this intervention.

Objectives Pneumonia is the largest infectious cause of death in children under 5 years globally, and limited resource settings bear an overwhelming proportion of this disease burden. Bubble continuous positive airway pressure (bCPAP), an accepted supportive therapy, is often thought of as cost-prohibitive in these settings. We hypothesise that bCPAP is a cost-effective intervention in a limited resource setting and this study aims to determine the cost-effectiveness of bCPAP, using Malawi as an example. Design Cost-effectiveness analysis. Setting District and central hospitals in Malawi. Participants Children aged 1 month–5 years with severe pneumonia, as defined by WHO criteria. Interventions Using a decision tree analysis, we compared standard of care (including low-flow oxygen and antibiotics) to standard of care plus bCPAP. Primary and secondary outcome measures For each treatment arm, we determined the costs, clinical outcomes and averted disability-adjusted life years (DALYs). We assigned input values from a review of the literature, including applicable clinical trials, and calculated an incremental cost-effectiveness ratio (ICER). Results In the base case analysis, the cost of bCPAP per patient was $15 per day and $41 per hospitalisation, with an incremental net cost of $64 per pneumonia episode. bCPAP averts 5.0 DALYs per child treated, with an ICER of $12.88 per DALY averted compared with standard of care. In one-way sensitivity analyses, the most influential uncertainties were case fatality rates (ICER range $9–32 per DALY averted). In a multi-way sensitivity analysis, the median ICER was $12.97 per DALY averted (90% CI, $12.77 to $12.99). Conclusion bCPAP is a cost-effective intervention for severe paediatric pneumonia in Malawi. These results may be used to inform policy decisions, including support for widespread use of bCPAP in similar settings.

Many countries use the cost-effectiveness thresholds recommended by the World Health Organization's Choosing Interventions that are Cost-Effective project (WHO-CHOICE) when evaluating health interventions. This project sets the threshold for cost-effectiveness as the cost of the intervention per disability-adjusted life-year (DALY) averted less than three times the country's annual gross domestic product (GDP) per capita. Highly cost-effective interventions are defined as meeting a threshold per DALY averted of once the annual GDP per capita. We argue that reliance on these thresholds reduces the value of cost-effectiveness analyses and makes such analyses too blunt to be useful for most decision-making in the field of public health. Use of these thresholds has little theoretical justification, skirts the difficult but necessary ranking of the relative values of locally-applicable interventions and omits any consideration of what is truly affordable. The WHO-CHOICE thresholds set such a low bar for cost-effectiveness that very few interventions with evidence of efficacy can be ruled out. The thresholds have little value in assessing the trade-offs that decision-makers must confront. We present alternative approaches for applying cost-effectiveness criteria to choices in the allocation of health-care resources.De nombreux pays utilisent les seuils de rentabilité recommandés par le projet WHO-CHOICE (Choosing Interventions that are Cost–Effective; en français: « choisir des interventions efficaces au meilleur coût ») de l'Organisation mondiale de la Santé lors de l'évaluation des interventions sanitaires. Ce projet définit le seuil de rentabilité comme étant égal au coût de l'intervention par espérance de vie corrigée de l'incapacité (EVCI) évitée moins trois fois le produit intérieur brut (PIB) annuel du pays par habitant. Les interventions très rentables sont définies comme celles satisfaisant un seuil par EVCI évitée égal à une fois le PIB annuel par habitant. Nous soutenons que le recours à ces seuils réduit la valeur des analyses de rentabilité et qu'il rend ces analyses trop grossières pour qu'elles soient utiles pour la prise de décision dans le domaine de la santé publique. L'utilisation de ces seuils est peu justifiée théoriquement, contourne le classement difficile mais nécessaire des valeurs relatives des interventions applicables localement et néglige l'examen de ce qui vraiment abordable. Les seuils de WHO-CHOICE fixent une limite de rentabilité si basse que très peu d'interventions présentant des preuves d'efficacité peuvent être exclues. Les seuils ont peu de valeur pour évaluer les compromis auxquels les décideurs doivent faire face. Nous présentons des approches alternatives pour l'application des critères de rentabilité aux choix liés à l'allocation des ressources de soins de santé.Numerosos países utilizan los umbrales de rentabilidad recomendados por el proyecto Elección de intervenciones rentables de la Organización Mundial de la Salud – (WHO-CHOICE) al evaluar las intervenciones de salud. Este proyecto establece el umbral de rentabilidad como el coste de la intervención por año de vida ajustado por discapacidad (AVAD) evitado, que es tres veces inferior al producto interno bruto anual del país (PIB) per cápita. Las intervenciones de rentabilidad elevada se definen como el cumplimiento de un umbral por AVAD evitado equivalente a una vez el PIB per cápita anual. Se arguye que la dependencia de estos umbrales reduce el valor de los análisis de rentabilidad y hace que dichos análisis sean demasiado contundentes para que resulten útiles en la mayoría de las decisiones en el campo de la salud pública. El uso de estos umbrales tiene una justificación teórica insuficiente, elude la clasificación difícil pero necesaria de los valores relativos de las intervenciones aplicables a nivel local y omite cualquier consideración de lo que es realmente asequible. Los umbrales de WHO-CHOICE establecen un límite de rentabilidad tan bajo que son muy pocas las intervenciones de eficacia probada que pueden descartarse. Los umbrales tienen poco valor a la hora de evaluar las ventajas y desventajas a las que los responsables de la toma de decisiones deben enfrentarse. Presentamos enfoques alternativos para la aplicación de los criterios de rentabilidad en las decisiones acerca de la asignación de los recursos de salud.تستخدم العديد من البلدان عتبات المردودية التي أوصى بها مشروع "اختيار التدخلات عالية المردود التابع لمنظمة الصحة العالمية" (WHO-CHOICE) عند تقدير التدخلات في مجال الصحة. ويحدد هذا المشروع عتبة المردودية على أنها تكلفة التدخل لكل سنة تم تفاديها من سنوات العمر المصححة باحتساب مدد العجز الأقل من ثلاث أضعاف الناتج الإجمالي المحلي السنوي للبلد لكل فرد. ويتم تعريف التدخلات عالية المردود على أنها تلبية العتبة لكل سنة تم تفاديها من سنوات العمر المصححة باحتساب مدد العجز لمرة واحدة من الناتج الإجمالي المحلي السنوي لكل فرد. ونرى أن الاعتماد على هذه العتبات يقلل من قيمة تحليلات المردودية ويجعل مثل هذه التحليلات عديمة الفائدة في معظم حالات اتخاذ القرار في مجال الصحة العمومية. ويستند استخدام هذه العتبات إلى مبرر نظري ضعيف ويتجنب الترتيب الصعب والضروري للقيم النسبية للتدخلات السارية على الصعيد المحلي ويغفل النظر عن النهج معقولة التكلفة بالفعل. وتحدد عتبات WHO-CHOICE عتبة دنيا للمردودية يمكن على أساسها استبعاد بضعة تدخلات ذات بيِّنات على الكفاءة. وتكون للعتبات قيمة قليلة في تقييم عمليات الموازنة التي يتعين على متخذي القرار مواجهتها. ونقدم نهجاً بديلة لتطبيق معايير المردودية على الاختيارات في تخصيص موارد الرعاية الصحية.许多国家在评估卫生干预措施时使用世界卫生组织WHO-CHOICE（选择具有成本效益的干预措施项目）推荐的成本效益阈值。该项目将成本效益阈值设定为避免单位残疾调整生命年（DALY）的干预措施的成本低于国家年度人均国内生产总值（GDP）三倍。将极具成本效益的干预措施定义为达到以单倍年度人均国内生产总值避免的单位DALY的成本的阈值。我们主张，对这些阈值的依赖减少了成本效益分析的价值，使这种分析太过生硬，以致于对大多数公共卫生领域的决策来说用处不大。使用这些阈值几乎没有理论依据，绕开了做起来很难但又不得不去做的对当地适用干预措施相对价值排名，忽略了对任何有关什么才真正实惠的考虑。WHO-CHOICE阈值为成本效益设定的门槛这样低，以至于为数不多具有效力证据的干预措施也会被排除在外。阈值在评估决策者必须面对的权衡上价值微乎其微。我们提出了医疗资源分配方面的选择上成本效益标准应用的替代方法。.Во многих странах используются пороговые значения эффективности затрат, рекомендованные рабочей программой ВОЗ «Выбор мероприятий, эффективных с точки зрения затрат» (WHO-CHOICE), при оценке проводимых мероприятий в области здравоохранения. Этот проект устанавливает пороговое значение эффективности затрат как стоимость мероприятия на количество предотвращенных лет жизни, утраченных в результате инвалидности (ДАЛИ), не превышающая три годовых валовых внутренних продукта (ВВП) страны на душу населения. При этом высокоэффективными мероприятиями считаются те, которые соответствуют пороговому значению на предотвращенное ДАЛИ в размере, не превышающем одного годового ВВП на душу населения. Мы утверждаем, что использование этих пороговых значений снижает стоимость анализа эффективности затрат и делает подобный анализ поверхностным для большинства случаев принятия решений в области общественного здравоохранения. Для использования этих пороговых значений не имеется достаточных теоретических обоснований, они упускают из виду трудоемкое, но необходимое ранжирование относительной стоимости применяемых локально мероприятий, а также не рассматривают доступность подобных мероприятий. Программой WHO-CHOICE устанавливается такая низкая планка для эффективности затрат, что лишь немногие мероприятия с признаками эффективности могут быть исключены. Эти пороговые значения не имеют большой ценности в процессе принятия компромиссных решений, с которыми приходится иметь дело отвественным лицам. Мы предлагаем альтернативные подходы для применения критериев эффективности затрат при выборе предпочтительных вариантов в процессе распределения ресурсов здравоохранения.

Background: Highly active antiretroviral therapy (HAART) provides dramatic health benefits for HIV-infected individuals in Africa, and widespread implementation of HAART is proceeding rapidly. Little is known about the cost and cost effectiveness of HAART programmes. Objective: To determine the incremental cost effectiveness of a home-based HAART programme in rural Uganda. Methods: A computer-based, deterministic cost-effectiveness model was used to assess a broad range of economic inputs and health outcomes. From the societal perspective, the cost effectiveness of HAART and cotrimoxazole prophylaxis was compared with cotrimoxazole alone, and with the period before either intervention. Data for 24 months were derived from a trial of home-based HAART in 1045 patients in the Tororo District in eastern Uganda. Costs and outcomes were projected out to 15 years. All costs are in year 2004 values. The main outcome measures were HAART programme costs, health benefits accruing to HAART recipients, averted HIV infections in adults and children and the resulting effects on medical care costs. The first-line HAART regimen consisted of standard doses of stavudine, lamivudine, and either nevirapine or, for patients with active tuberculosis, efavirenz. Second-line therapy consisted of tenofovir, didanosine and lopinavir/ritonavir. For children, first-line HAART consisted of zidovudine, lamivudine and nevirapine syrup; second-line therapy was stavudine, didanosine and lopinavir/ritonavir. Results: The HAART programme, standardized for 1000 patients, cost an incremental $US1.39 million in its first 2 years. Compared with cotrimoxazole prophylaxis alone, the programme reduced mortality by 87%, and averted 6861 incremental disability-adjusted life-years (DALYs). Benefits were accrued from reduced mortality in HIV-infected adults (67.5% of all benefits), prevention of death in HIV-negative children (20.7%), averted HIV infections in adults (9.1%) and children (1.0%), and improved health status (1.7%). The net programme cost, including the medical cost implications of these health benefits, was $US4.10 million. The net cost per DALY averted was $US597 compared with cotrimoxazole alone. Many HIV interventions have a cost-effectiveness ratio in the range of $US1-150 per DALY averted. Conclusions: This study suggests that a home-based HAART programme in rural Africa may be more cost effective than most previous estimates for facility-based HAART programmes, but remains less cost effective than many HIV prevention and care interventions, including cotrimoxazole prophylaxis.

Background: A rapid scaling up of HIV interventions in India is anticipated, but systematic information on how costs of HIV interventions change over time and programme scale is not available to inform planning. Methods: We studied the changes in unit costs of two major interventions, voluntary counseling and testing (VCT) and sex worker programmes in the south Indian state of Andhra Pradesh between 2002-2003 and 2005-2006 fiscal years. Economic costs (from the provider perspective) and output data from 17 publicly funded VCT centers and 14 sex worker programmes were collected using standardized methods. We calculated unit costs for each programme in each period and explored possible reasons for the changes seen. Results: In 2005-2006, the VCT centers served 66445 clients and the sex worker programmes served 32 550. The unit cost of providing VCT dropped over 3 years by half to Indian Rupees (INR) 147.5 (US$3.33) mainly because the number of clients doubled. There was no decrease in the average time spent counseling each client. The unit cost of providing services to sex workers increased 2.4 times over 3 years to INR 1401 (US$31.6) as a result of increases in male condom distribution, staff salaries and training, and treatment for sexually transmitted infections, all suggesting improved services. Conclusion: The unit cost of these two interventions changed dramatically over a 3-year period, but in opposite directions. The current unit cost for VCT in Andhra Pradesh is much lower than the estimated global average for low-income settings. These local longitudinal cost data are useful to inform the currently planned scaling up of HIV interventions in India.

OBJECTIVE. We undertook a decision analysis to evaluate the economic and health effects and incremental cost-effectiveness of using targeted tuberculin skin testing, compared with universal screening or no screening, before kindergarten.METHODS. We constructed a decision tree to determine the costs and clinical outcomes of using targeted testing compared with universal screening or no screening. Baseline estimates for input parameters were taken from the medical literature and from California health jurisdiction data. Sensitivity analyses were performed to determine plausible ranges of associated outcomes and costs. We surveyed California health jurisdictions to determine the prevalence of mandatory universal tuberculin skin testing.RESULTS. In our base-case scenario, the cost to prevent an additional case of tuberculosis by using targeted testing, compared with no screening, was $524897. The cost to prevent an additional case by using universal screening, compared with targeted testing, was $671398. The incremental cost of preventing a case through screening remained above $100000 unless the prevalence of tuberculin skin testing positivity increased to >10%. More than 51% of children entering kindergarten in California live where tuberculin skin testing is mandatory.CONCLUSIONS. The cost to prevent a case of tuberculosis by using either universal screening or targeted testing of kindergarteners is high. If targeted testing replaced universal tuberculin skin testing in California, then $1.27 million savings per year would be generated for more cost-effective strategies to prevent tuberculosis. Improving the positive predictive value of the risk factor tool or applying it to groups with higher prevalence of latent tuberculosis would make its use more cost-effective. Universal tuberculin skin testing should be discontinued, and targeted testing should be considered only when the prevalence of risk factor positivity and the prevalence of tuberculin skin testing positivity among risk factor–positive individuals are high enough to meet acceptable thresholds for cost-effectiveness.

Background: Daily prophylaxis with trimethoprim-sulfamethoxazole (cotrimoxazole) by persons with HIV reduces morbidity and mortality and is recommended by Joint United Nations Program on HIV/AIDS and World Health Organization (WHO), but there are limited published cost-effectiveness data for this intervention. We assessed the cost-effectiveness of cotrimoxazole prophylaxis for persons living with HIV in rural Uganda. Methods: We modeled the cost-effectiveness of daily cotrimoxazole prophylaxis based on clinical results and operational data from a prospective cohort study of home-based care delivery to adults and children with HIV in rural Uganda who were older than the age of 5 years. Main outcome measures were net program cost and disabilityadjusted life-years (DALYs) gained. We examined the provision of cotrimoxazole prophylaxis for (A) all HIV-infected individuals regardless of immunologic or clinical criteria; (B) those with WHO stage 2 or more advanced disease; (C) those with CD4 cell counts ,500 cells/mL; and (D) those meeting criteria B or C, the current WHO recommendation. We calculated the costs and effectiveness of these 4 screening algorithms compared with no cotrimoxazole prophylaxis and calculated incremental cost-effectiveness ratios. We performed univariate and multivariate sensitivity analyses. Results: Cotrimoxazole prophylaxis for all HIV-infected individuals (algorithm A) produced 7.3 life-years and 7.55 DALYs per 100 persons over 1 year compared with no prophylaxis. Using this screening algorithm, the intervention saved $2.50 per person-year. The program costs and the DALYs gained by algorithms A, B, and D were more favorable than those for algorithm C. Among algorithms A, B, and D, strategies using screening algorithms for WHO stage or CD4 cell counts were more costly and marginally less effective than providing cotrimoxazole prophylaxis to all HIV-infected individuals. Conclusions: Daily cotrimoxazole prophylaxis for HIV-infected individuals is highly cost-effective in rural Uganda. The use of screening algorithms to identify individuals with advanced HIV disease may result in higher program costs and less favorable costeffectiveness.

Background : Co-infection with malaria and other infectious diseases has been shown to increase viral load and accelerate HIV disease progression. A recent study in Kenya demonstrated that providing long-lasting insecticide-treated bednets (LLIN) and water filters (WF) to HIV-positive adults with CD4 >350 cells/mm 3 significantly reduced HIV progression. Design : We conducted a cost analysis to estimate the potential net financial savings gained by delaying HIV progression and increasing the time to antiretroviral therapy (ART) eligibility through delivering LLIN and WF to 10% of HIV-positive adults with CD4 >350 cells/mm 3 in Kenya. Results : Given a 3-year duration of intervention benefit, intervention unit cost of US$32 and patient-year ART cost of US$757 (2011 US$), over the lifetime of ART patients, in Kenya, we estimated the intervention could yield a return on investment (ROI) of 11 (95% uncertainty range [UR]: 5–23), based on a cost of about US$2 million and savings in ART costs of about US$26 million (95% UR: 8–50) (discounted at 3%). Our findings were subjected to a number of sensitivity analyses. Of note, deferral of time to ART eligibility could potentially result in 3,000 new HIV infections not averted by ART and thus decrease ART cost savings to US$14 million, decreasing the ROI to 6. Conclusions : Provision of LLIN and WF could be a cost-saving and practical method to defer time to ART eligibility in the context of highly resource-constrained environments experiencing donor fatigue for HIV/AIDS programs.

There is wide agreement that an effective response to the global HIV epidemic requires very substantial resources. This consensus has been partially translated into increasing contributions to combat the epidemic (UNAIDS 2004). The need to spend this money efficiently can hardly be overstated: the lives of millions depend upon how effectively available funds are allocated. Available studies on the cost and cost-effectiveness of HIV prevention programs in developing countries are very limited in number, as well as in the range of prevention strategies and geographic settings examined (Marseille, Hofmann, and Kahn 2002). “Prevent AIDS: Network for Cost-Effectiveness Analysis” (PANCEA), is a three-year, five-country study funded by the U.S. National Institutes of Health. It has the purpose of providing essential information and analysis for an improved allocation of HIV prevention funds in developing countries. The study includes five countries: India, Mexico, Russia, South Africa, and Uganda. This article reviews PANCEA's data collection methods. Our purpose is two-fold. First, we aim to explicate the methods and data sources used in PANCEA. Second, we want to give other health services researchers sufficient information to judge the potential suitability of adapting PANCEA's approach to their own efforts. Further details on the project and key documents (e.g., instruments) can be found in the online-only Appendix to this article available at http://www.blackwell-synergy.com, at the PANCEA link at http://hivinsite.ucsf.edu/InSite?page=pancea, and from the authors. The remainder of the paper addresses PANCEA's conceptual approach, data collection tools, data collection process, challenges and limitations, early findings, and applications for other health program assessments.

Each year about 2 million babies are born to HIV-1- infected women. Despite widespread knowledge of proven methods to prevent mother-to-child transmission (MTCT) of the virus most infants at risk of contracting the infection from their mothers receive no prophylactic intervention. This inaction leads to the infection and ultimate death of about 800 000 children per year. It has been known since 1994 that MTCT is largely preventable and interventions appropriate for use in the developing world have been available since 1999. Singledose intrapartum and neonatal nevirapine—the simplest and perhaps most effective of the short-course antiretroviral regimens studied—has been available free of charge from the manufacturer since 2000. Nevertheless few women have access to MTCT-prevention services. In the more than 3 years since its inception the donation programme has shipped only 189 000 courses of the drug a tiny fraction (

Gestational diabetes mellitus (GDM) is an increasing cause of morbidity in women and their offspring. Screening and intervention can reduce perinatal and most likely also long-term diabetes consequences. There have been many economic studies, but not recently systematically compared. We conducted a systematic search and abstraction of cost-effectiveness and cost-utility studies from 2002 to 2014. We standardized all findings to 2014 US dollars. We found that cost-effectiveness ratios varied widely. Most variation was found to be due to differences in geographic setting, diagnostic criteria and intervention approaches, and outcomes (e.g., inclusion or exclusion of long-term type 2 diabetes risk and associated costs). We concluded that incorporation of long-term benefits of GDM screening and treatment has huge impact on cost-effectiveness estimates. Based on the large methodological heterogeneity and varying results in the existing body of evidence, we find it unreasonable to outline any global recommendations. For future economic studies, we recommend inclusion of long-term outcomes and adaptation to local preferences, as well as examination of the impact of the diagnostic criteria recently proposed by the International Association of Diabetes in Pregnancy Study Groups (IADPSG).

Summary Data on the cost-effectiveness of HIV prevention in sub-Saharan Africa and on highly active antiretroviral therapy (HAART) indicate that prevention is at least 28 times more cost effective than HAART. We aim to show that funding HAART at the expense of prevention means greater loss of life. To maximise health benefits, the next major increments of HIV funding in sub-Saharan Africa should be devoted mainly to prevention and to some non-HAART treatment and care. Funds should be allocated to HAART primarily for demonstration projects that will help prepare for scaled-up HAART provision following broad population coverage by prevention programmes. UNAIDS and the London School of Hygiene and Tropical Medicine recently estimated that at least US$9·2 billion annually is required to mount an appropriate response to the HIV pandemic, including substantial funding for HAART. To date, US$1·96 billion has been committed to the newly-established UN Global Fund to Fight AIDS, Tuberculosis, and Malaria. It is a moral imperative that expanded programmes to control HIV be implemented without delay, and that the goal of US$9·2 billion or more in annual spending be attained as rapidly as possible. The findings and recommendations of this analysis pertain to the phasing in of additional HIV-related activities during the current period of improved but inadequate funding.

Each year more than 350,000 babies acquire HIV infection from their mother, mainly in Africa. As sadly constant as this fact is, the policy environment around crafting an effective response has changed rapidly and unpredictably. Sequential advances in antiretroviral therapy, preserving effectiveness with far more practical regimens, have repeatedly upped the ante for action, and have also transformed policy issues. This paper relates a modeling story-something of a saga in its meandering course-closely intertwined with evolving policy. Our models have achieved a modicum of success. They have framed several policy discussions and have at least once led directly to an important policy development, as we discuss below. What made that possible? We've identified four elements: solid modeling, which establishes credibility; connected and savvy collaborators, who permit us to reach key decisionmakers (both logistically and in the sense of gaining their serious interest); our policy orientation, which has kept the models practical; and quick adaptations of the model, allowing our participation in fast-moving policy developments. Our models portray the risk of mother-to-child HIV transmission during pregnancy, delivery, and breast-feeding. They also portray the reduction in risk associated with the use of antiretroviral therapy (typically a 40 to 60 percent reduction), and with use of formula feeding instead of breast-feeding. Finally, the models estimate the costs of HIV testing, intervention, and HIV disease in children-in order to estimate the net Costs per HIV infection averted and per Disability Adjusted Life Year (DALY) gained.

Objective This study estimated the health impact, cost and cost-effectiveness of an integrated prevention campaign (IPC) focused on diarrhoea, malaria and HIV in 70 countries ranked by per capita disability-adjusted life-year (DALY) burden for the three diseases. Methods We constructed a deterministic cost-effectiveness model portraying an IPC combining counselling and testing, cotrimoxazole prophylaxis, referral to treatment and condom distribution for HIV prevention; bed nets for malaria prevention; and provision of household water filters for diarrhoea prevention. We developed a mix of empirical and modelled cost and health impact estimates applied to all 70 countries. One-way, multiway and scenario sensitivity analyses were conducted to document the strength of our findings. We used a healthcare payer9s perspective, discounted costs and DALYs at 3% per year and denominated cost in 2012 US dollars. Primary and secondary outcomes The primary outcome was cost-effectiveness expressed as net cost per DALY averted. Other outcomes included cost of the IPC; net IPC costs adjusted for averted and additional medical costs and DALYs averted. Results Implementation of the IPC in the 10 most cost-effective countries at 15% population coverage would cost US$583 million over 3 years (adjusted costs of US$398 million), averting 8.0 million DALYs. Extending IPC programmes to all 70 of the identified high-burden countries at 15% coverage would cost an adjusted US$51.3 billion and avert 78.7 million DALYs. Incremental cost-effectiveness ranged from US$49 per DALY averted for the 10 countries with the most favourable cost-effectiveness to US$119, US$181, US$335, US$1692 and US$8340 per DALY averted as each successive group of 10 countries is added ordered by decreasing cost-effectiveness. Conclusions IPC appears cost-effective in many settings, and has the potential to substantially reduce the burden of disease in resource-poor countries. This study increases confidence that IPC can be an important new approach for enhancing global health.

Objectives To help stakeholders identify and prioritise countries with the best opportunities for implementation of an integrated prevention campaign (IPC) focused on diarrhoea, malaria and HIV prevention. Design Cross-sectional analysis of country-specific epidemiological data using an index tool developed for this purpose. Setting We calculated the total disability-adjusted life years (DALYs) attributed to diarrhoea, malaria and HIV for 214 World Bank economies. Criteria for inclusion were: low-income and middle-income countries, and total annual DALY burden in the top tertile (≥87 000 DALYs). 70 countries met inclusion criteria and were included in our opportunity analysis. Outcome measures We synthesised data on 10 indicators related to the potential reduction in burden and new coverage achievable by an IPC. We scored and ranked countries based on three summary opportunity metrics: DALYs per capita across the diseases, a composite score of tertile rankings of burden for each disease, and a score combining burden and intervention opportunity. Results We estimated the total annual global burden attributable to diarrhoea, malaria and HIV at 135 million DALYs. All of the countries with the highest opportunity for implementation of a diarrhoea, malaria and HIV IPC are in sub-Saharan Africa, regardless of opportunity metric used. Although the overall rank order changes, 16 countries rank among the top 23 highest opportunity countries for all three metrics. Conclusions Stakeholders can use this objective metric-based approach to prioritise countries for IPC scale-up. Priority countries are largely robust to the opportunity metric chosen.

Gestational diabetes mellitus (GDM) is associated with elevated risks of perinatal complications and type 2 diabetes mellitus, and screening and intervention can reduce these risks. We quantified the cost, health impact and cost-effectiveness of GDM screening and intervention in India and Israel, settings with contrasting epidemiologic and cost environments.We developed a decision-analysis tool (the GeDiForCE™) to assess cost-effectiveness. Using both local data and published estimates, we applied the model for a general medical facility in Chennai, India and for the largest HMO in Israel. We computed costs (discounted international dollars), averted disability-adjusted life years (DALYs) and net cost per DALY averted, compared with no GDM screening.The programme costs per 1000 pregnant women are $259,139 in India and $259,929 in Israel. Net costs, adjusted for averted disease, are $194,358 and $76,102, respectively. The cost per DALY averted is $1626 in India and $1830 in Israel. Sensitivity analysis findings range from $628 to $3681 per DALY averted in India and net savings of $72,420-8432 per DALY averted in Israel.GDM interventions are highly cost-effective in both Indian and Israeli settings, by World Health Organization standards. Noting large differences between these countries in GDM prevalence and costs, GDM intervention may be cost-effective in diverse settings.

Background We estimated the unit costs and cost-effectiveness of a government ART program in 45 sites in Zambia supported by the Centre for Infectious Disease Research Zambia (CIDRZ). Methods We estimated per person-year costs at the facility level, and support costs incurred above the facility level and used multiple regression to estimate variation in these costs. To estimate ART effectiveness, we compared mortality in this Zambian population to that of a cohort of rural Ugandan HIV patients receiving co-trimoxazole (CTX) prophylaxis. We used micro-costing techniques to estimate incremental unit costs, and calculated cost-effectiveness ratios with a computer model which projected results to 10 years. Results The program cost $69.7 million for 125,436 person-years of ART, or $556 per ART-year. Compared to CTX prophylaxis alone, the program averted 33.3 deaths or 244.5 disability adjusted life-years (DALYs) per 100 person-years of ART. In the base-case analysis, the net cost per DALY averted was $833 compared to CTX alone. More than two-thirds of the variation in average incremental total and on-site cost per patient-year of treatment is explained by eight determinants, including the complexity of the patient-case load, the degree of adherence among the patients, and institutional characteristics including, experience, scale, scope, setting and sector. Conclusions and Significance The 45 sites exhibited substantial variation in unit costs and cost-effectiveness and are in the mid-range of cost-effectiveness when compared to other ART programs studied in southern Africa. Early treatment initiation, large scale, and hospital setting, are associated with statistically significantly lower costs, while others (rural location, private sector) are associated with shifting cost from on- to off-site. This study shows that ART programs can be significantly less costly or more cost-effective when they exploit economies of scale and scope, and initiate patients at higher CD4 counts.

Gestational diabetes mellitus (GDM) is increasingly recognized as an opportunity for early prevention of diabetes and other diseases over the lifespan, and may be responsible for up to 30% of cases of type 2 diabetes. A newly developed mathematical model (the GDModel) provides provisional estimates of the cost and health impact of various GDM screening and management choices, and calculates averted disability-adjusted life-years (DALYs). The model was piloted in 5 different healthcare facilities in India and Israel. Universal screening of pregnant women followed by postpartum lifestyle management yielded net savings of US$78 per woman with GDM in India and US$1945 per woman in Israel. The estimated DALYs averted were 2.33 in India and 3.10 in Israel. With lower GDM prevalence, intervention efficacy, and type 2 diabetes incidence, the intervention had a net cost in India, with a cost per DALY averted of US$11.32. This was far below the WHO definition of "very cost-effective," set at annual GDP per capita. The intervention in Israel remained cost-saving. GDM screening and postpartum lifestyle management are either cost-saving or have a net cost but an attractive cost-effectiveness ratio. Some input values are currently being refined. Nevertheless, the current findings of cost-savings or favorable cost-effectiveness are robust to a wide range of plausible input values, including highly unfavorable values. The GDModel will be further developed into a user-friendly tool that can guide policy-makers on decisions regarding GDM screening strategies and guidelines.

The association between gestational diabetes mellitus (GDM), perinatal complications and long-term morbidity is gaining increased attention. However, the global burden of GDM and the existing responses are not fully understood. We aimed to assess country prevalence and to summarize practices related to GDM screening and management.Data on prevalence and country practices were obtained from a survey administered to diabetologists, obstetricians and others working on GDM in 173 countries.GDM prevalence estimates range from1% to 28%, with data derived from expert estimates, and single-site, multi-site and national prevalence assessments. Seventy-four percent of countries that completed the survey have national GDM guidelines or recommendations. Countries use a variety of screening approaches. In the countries where universal screening is recommended, the percentage of pregnant women screened ranges from 10% to90%.We found large variations in estimated GDM prevalence, but direct comparison between countries is difficult due to different diagnostic strategies and subpopulations. Many countries do not perform systematic screening for GDM, and practices often diverge from guidelines. Countries need to carefully assess the cost and health impact of scaling up GDM screening and management in order to identify the best policy option for their population.

textabstractBackground: Trials in Africa indicate that medical adult male circumcision (MAMC) reduces the risk of HIV by 60%. MAMC may avert 2 to 8 million HIV infections over 20 years in sub-Saharan Africa and cost less than treating those who would have been infected. This paper estimates the financial and human resources required to roll out MAMC and the net savings due to reduced infections. Methods: We developed a model which included costing, demography and HIV epidemiology. We used it to investigate 14 countries in sub-Saharan Africa where the prevalence of male circumcision was lower than 80% and HIV prevalence among adults was higher than 5%, in addition to Uganda and the Nyanza province in Kenya. We assumed that the roll-out would take 5 years and lead to an MC prevalence among adult males of 85%. We also assumed that surgery would be done as it was in the trials. We calculated public program cost, number of full-time circumcisers and net costs or savings when adjusting for averted HIV treatments. Costs were in USD, discounted to 2007. 95% percentile intervals (95% PI) were estimated by Monte Carlo simulations. Results: In the first 5 years the number of circumcisers needed was 2 282 (95% PI: 2 018 to 2 959), or 0.24 (95% PI: 0.21 to 0.31) per 10 000 adults. In years 6-10, the number of circumcisers needed fell to 513 (95% PI: 452 to 664). The estimated 5-year cost of rolling out MAMC in the public sector was $919 million (95% PI: 726 to 1 245).The cumulative net cost over the first 10 years was $672 million (95% PI: 437 to 1 021) and over 20 years there were net savings of $2.3 billion (95% PI: 1.4 to 3.4). Conclusion: A rapid roll-out of MAMC in sub-Saharan Africa requires substantial funding and a high number of circumcisers for the first five years. These investments are justified by MAMC's substantial health benefits and the savings accrued by averting future HIV infections. Lower ongoing costs and continued care savings suggest long-term sustainability.

Background Prevention of mother to child transmission (PMTCT) is an important part of the effort to control HIV. PMTCT services are mostly provided at public sector government hospitals in India. Systematic data on the cost and efficiency of providing PMTCT services in India are not available readily for further planning. Methods Cost and output data were collected at 16 sampled PMTCT centres in the south Indian state of Andhra Pradesh using standardized methods. The services provided were analysed, and the relation of unit cost of services with scale was assessed. Results In the 2005–2006 fiscal year, 125,073 pregnant women received PMTCT services at the 16 centres (range 2,939 to 20,896, median 5,679). The overall HIV positive rate among those tested was 1.67%. Of the total economic cost, the major components were personnel (47.3%) and recurrent goods (31.7%). For the 16 PMTCT centres, the average economic cost per post-HIV-test counselled pregnant woman was Indian Rupees (INR) 98.9 (US$ 2.23), ranging 2.7-fold from INR 71.4 (US$ 1.61) to INR 189.9 (US$ 4.29). The economic cost per mother-neonate pair who received nevirapine had a higher variation, ranging 41-fold for the 16 centres from INR 4,354 (US$ 98) to INR 179,175 (US$ 4,047), average INR 10,210 (US$ 231), with very high unit cost at some centres where HIV prevalence among pregnant women and the total volume of services were both low. Scale had a significant inverse relation with both of the unit costs, per post-HIV-test counselled pregnant woman and per mother-neonate pair who received nevirapine. In addition, HIV prevalence among pregnant women had a significant inverse relation with unit cost per mother-neonate pair who received nevirapine. Conclusion Although the variation between PMTCT centres for unit cost per post-HIV-test counselled pregnant woman was modest that per mother-neonate pair receiving nevirapine was over 40-fold. The extremely high unit cost for each mother-neonate pair receiving nevirapine at some centres suggests that the new approach of combining PMTCT services with voluntary counselling and testing services that has recently been started in India could potentially offer better efficiency.

© 2016 American Medical Association. All rights reserved. Importance Novel treatments for hepatitis C virus (HCV) infection are highly efficacious but costly. Thus, many insurers cover therapy only in advanced fibrosis stages. The added health benefits and costs of early treatment are unknown. Objective To assess the cost-effectiveness of (1) treating all patients with HCV vs only those with advanced fibrosis and (2) treating each stage of fibrosis. Design, Setting, and Participants This study used a decision-analytic model for the treatment of HCV genotype 1. The model used a lifetime horizon and societal perspective and was representative of all US patients with HCV genotype 1 who had not received previous treatment. Comparisons in the model included antiviral treatment of all fibrosis stages (METAVIR [Meta-analysis of Histological Data in Virial Hepatitis] stages F0 [no fibrosis] to F4 [cirrhosis]) vs treatment of stages F3 (numerous septa without cirrhosis) and F4 only and by specific fibrosis stage. Data were collected from March 1 to September 1, 2014, and analyzed from September 1, 2014, to June 30, 2015. Interventions Six HCV therapy options (particularly combined sofosbuvir and ledipasvir therapy) or no treatment. Main Outcomes and Measures Cost and health outcomeswere measured using total medical costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs), calculated as the difference in costs between strategies divided by the difference inQALYs. Results We simulated 1000 individuals, but present the Results normalized to a single HCV-infected person. In the base-case analysis, among patients receiving 8 or 12 weeks of sofosbuvir-ledipasvir treatment, treating all fibrosis stages compared with treating stages F3 and F4 adds 0.73 QALYs and $28 899, for an ICER of $39 475 per QALY gained. Treating at stage F2 (portal fibrosis with rare septa) costs $19 833 per QALY gained vs waiting until stage F3; treating at stage F1 (portal fibrosis without septa), $81 165 per QALY gained compared with waiting until stage F2; and treating at stage F0, $187 065 per QALY gained compared with waiting until stage F1. Results for other regimens show a similar pattern. At base-case drug prices, treating 50% of all eligible US patients with HCV genotype 1 would cost $53 billion. In sensitivity analyses, the ICER for treating all stages vs treating stages F3 and F4 was most sensitive to cohort age, drug costs, utility values in stages F1 and F2, and percentage of patients eligible for 8-week therapy. Except for patients aged 70 years, the ICER remains less than $100 000 per QALY gained. A 46%reduction in cost of sofosbuvir-ledipasvir therapy decreases the ICER for treating at all fibrosis stages by 48%. Conclusions and Relevance In this simulated model, treating HCV infection at early stages of fibrosis appeared to improve health outcomes and to be cost-effective but incurred substantial aggregate costs. The findings may have implications for health care coverage policies and clinical decision making.

Background Economic theory and limited empirical data suggest that costs per unit of HIV prevention program output (unit costs) will initially decrease as small programs expand. Unit costs may then reach a nadir and start to increase if expansion continues beyond the economically optimal size. Information on the relationship between scale and unit costs is critical to project the cost of global HIV prevention efforts and to allocate prevention resources efficiently. Methods The "Prevent AIDS: Network for Cost-Effectiveness Analysis" (PANCEA) project collected 2003 and 2004 cost and output data from 206 HIV prevention programs of six types in five countries. The association between scale and efficiency for each intervention type was examined for each country. Our team characterized the direction, shape, and strength of this association by fitting bivariate regression lines to scatter plots of output levels and unit costs. We chose the regression forms with the highest explanatory power (R2). Results Efficiency increased with scale, across all countries and interventions. This association varied within intervention and within country, in terms of the range in scale and efficiency, the best fitting regression form, and the slope of the regression. The fraction of variation in efficiency explained by scale ranged from 26% – 96%. Doubling in scale resulted in reductions in unit costs averaging 34.2% (ranging from 2.4% to 58.0%). Two regression trends, in India, suggested an inflection point beyond which unit costs increased. Conclusion Unit costs decrease with scale across a wide range of service types and volumes. These country and intervention-specific findings can inform projections of the global cost of scaling up HIV prevention efforts.

However, the cost of providing ART to individuals with CD4g350 in Sub-Saharan Africa has not been well estimated. This remains a major barrier to optimal global cost projections for accelerating the scale-up of ART. Our objective was to compute costs of ART delivery to high CD4+count individuals in a typical rural Ugandan health center-based HIV clinic, and use these data to construct scenarios of efficient ART scale-up.MethodsWithin a clinical study evaluating streamlined ART delivery to 197 individuals with CD4+ cell counts g350 cells/uL (EARLI Study: NCT01479634) in Mbarara, Uganda, we performed a micro-costing analysis of administrative records, ART prices, and time-and-motion analysis of staff work patterns. We computed observed per-person-per-year (ppy) costs, and constructed models estimating costs under several increasingly efficient ART scale-up scenarios using local salaries, lowest drug prices, optimized patient loads, and inclusion of viral load (VL) testing.FindingsAmong 197 individuals enrolled in the EARLI Study, median pre-ART CD4+ cell count was 569/uL (IQR 451-716). Observed ART delivery cost was $628 ppy at steady state. Models using local salaries and only core laboratory tests estimated costs of $529/$445 ppy (+/-VL testing, respectively). Models with lower salaries, lowest ART prices, and optimized healthcare worker schedules reduced costs by $100-200 ppy. Costs in a maximally efficient scale-up model were $320/$236 ppy (+/- VL testing). This included $39 for personnel, $106 for ART, $130/$46 for laboratory tests, and $46 for administrative/other costs. A key limitation of this study is its derivation and extrapolation of costs from one large rural treatment program of high CD4+ count individuals.ConclusionsIn a Ugandan HIV clinic, ART delivery costs--including VL testing--for individuals with CD4g350 were similar to estimates from high-efficiency programs. In higher efficiency scale-up models, costs were substantially lower. These favorable costs may be achieved because high CD4+ count patients are often asymptomatic, facilitating more efficient streamlined ART delivery. Our work provides a framework for calculating costs of efficient ART scale-up models using accessible data from specific programs and regions.

The objective of this study is to assess the costs cost-effectiveness and HIV epidemic impact of 3 antiretroviral therapy (ART) policy options. We constructed an epidemiologic model to predict the course of the HIV epidemic in the absence of expanded ART availability. Based on background studies of the willingness to pay for ART among patients with AIDS of the costs to the government of the alternative treatment interventions and of ARTs likely effects on HIV transmission we simulated the consequences of 3 possible alternative government ART policies. A program to reduce the negative consequences of the currently unstructured private-sector provision of ART is the most cost-effective of the 3 options at a 10% discount rate and least cost-effective at a 3% rate. The costs and cost-effectiveness of all options are highly sensitive to the effect of ART on condom use. The design of ART policy should capitalize on the potential of ART to decrease HIV transmission through institutional arrangements that reward effective prevention programs thereby raising the likelihood that treatment has beneficial rather than negative external effects.

Background Immigrants to the U.S. are required to undergo overseas screening for tuberculosis (TB), but the value of evaluation and treatment following entry to the U.S. is not well understood. We determined the cost-effectiveness of domestic follow-up of immigrants identified as tuberculosis suspects through overseas screening. Methods Using a stochastic simulation for tuberculosis reactivation, transmission, and follow-up for a hypothetical cohort of 1000 individuals, we calculated the incremental cost-effectiveness of follow-up and evaluation interventions. We utilized published literature, California Reports of Verified Cases of Tuberculosis (RVCTs), demographic estimates from the California Department of Finance, Medicare reimbursement, and Medi-Cal reimbursement rates. Our target population was legal immigrants to the United States, our time horizon is twenty years, and our perspective was that of all domestic health-care payers. We examined the intervention to offer latent tuberculosis therapy to infected individuals, to increase the yield of domestic evaluation, and to increase the starting and completion rates of LTBI therapy with INH (isoniazid). Our outcome measures were the number of cases averted, the number of deaths averted, the incremental dollar cost (year 2004), and the number of quality-adjusted life-years saved. Results Domestic follow-up of B-notification patients, including LTBI treatment for latently infected individuals, is highly cost-effective, and at times, cost-saving. B-notification follow-up in California would reduce the number of new tuberculosis cases by about 6–26 per year (out of a total of approximately 3000). Sensitivity analysis revealed that domestic follow-up remains cost-effective when the hepatitis rates due to INH therapy are over fifteen times our best estimates, when at least 0.4 percent of patients have active disease and when hospitalization of cases detected through domestic follow-up is no less likely than hospitalization of passively detected cases. Conclusion While the current immigration screening program is unlikely to result in a large change in case rates, domestic follow-up of B-notification patients, including LTBI treatment, is highly cost-effective. If as many as three percent of screened individuals have active TB, and early detection reduces the rate of hospitalization, net savings may be expected.

Safe water systems (SWSs) have been shown to reduce diarrhea and death. We examined the cost-effectiveness of SWS for HIV-affected households using health outcomes and costs from a randomized controlled trial in Tororo, Uganda. SWS was part of a home-based health care package that included rapid diarrhea diagnosis and treatment of 196 households with relatively good water and sanitation coverage. SWS use averted 37 diarrhea episodes and 310 diarrhea-days, representing 0.155 disability-adjusted life year (DALY) gained per 100 person-years, but did not alter mortality. Net program costs were 5.21 dollars/episode averted, 0.62 dollars/diarrhea-day averted, and 1,252 dollars/DALY gained. If mortality reduction had equaled another SWS trial in Kenya, the cost would have been 11 dollars/DALY gained. The high SWS cost per DALY gained was probably caused by a lack of mortality benefit in a trial designed to rapidly treat diarrhea. SWS is an effective intervention whose cost-effectiveness is sensitive to diarrhea-related mortality, diarrhea incidence, and effective clinical management.

The objective of this study was to determine the financial incentives that companies have to treat HIV-infected employees, in a health care services company in Kampala, Uganda.Cost-benefit analysis from the company's perspective of three interventions to treat HIV-infected employees.The costs and benefits of each intervention were compared with no intervention and with each other: cotrimoxazole prophylaxis (CTX) starting at WHO stage 2; highly active antiretroviral therapy (HAART) plus CTX starting at WHO stage 2; and a 'hybrid' strategy that begins with CTX at WHO stage 2 and later includes HAART. The 5-year health and economic outcomes were calculated using a Markov model. Inputs for disease progression rates and effects of HIV on company costs were derived from published and unpublished data and a survey administered to company officers.The analysis showed that the 'hybrid' intervention is the most cost-effective. For 100 skilled employees it would save the company 38,939 US dollars and 73 disability adjusted life-years (DALYs). For unskilled workers 'CTX' is the most cost effective and would save 16,417 US dollars and 60 DALYs. 'Hybrid' has an incremental cost-effectiveness ratio of 45 US dollars per DALY for unskilled workers whereas HAART is far less economical at an incremental cost per DALY of 4118 US dollars. For 'CTX', net savings are preserved across the full range of input values.A 'hybrid' intervention combining CTX prophylaxis followed by HAART would generate savings to a Ugandan company. Governments and other donors may find opportunities to share costs with the private sector as part of their phase-in strategy for antiretroviral therapy.

Demand for HIV voluntary counselling and testing (VCT) will increase as HIV prevention and treatment scale up in South Africa. Understanding the cost of delivering VCT will inform funding decisions.To determine the cost per client completing VCT (pretest counselling, testing and post-test counselling) in a non-research- based programme using rapid-test technology.One year of expenditure and output data were collected retrospectively as part of the PANCEA (Prevent AIDS: Network for Cost-Effectiveness Analysis) study. Market prices were determined for donated resources.An urban, church-based, non-profit organisation that offers rapid-test VCT services in KwaZulu-Natal, South Africa.Financial expenditure for the 2002/2003 fiscal year was 39,761 dollars (calculated using an average conversion rate for July 2003, which was 0.133). Using market prices for donated resources, the economic cost for the year was estimated at 67,248 dollars. Six hundred and sixty-two clients completed VCT, resulting in financial expenditure of 60.06 dollars per client and an economic cost of 101.58 dollars per client. Financial expenditures and economic costs per client decreased over the year by 66% because expenses remained stable as more clients were served.The cost of providing VCT services was higher than previously reported, but declined with expanding scale.

Background Control of sexually transmitted infections (STIs) is an important part of the effort to reduce the risk of HIV/AIDS. STI clinics in the government hospitals in India provide services predominantly to the poor. Data on the cost and efficiency of providing STI services in India are not available to help guide efficient use of public resources for these services. Methods Standardised methods were used to obtain detailed cost and output data for the 2003–2004 fiscal year from written records and interviews in 14 government STI clinics in the Indian state of Andhra Pradesh. The economic cost per patient receiving STI treatment was calculated, and the variations of total and unit costs across the STI clinics analysed. Multivariate regression technique was used to estimate incremental unit costs. The optimal number of STIs that could be handled by the clinics was estimated. Results 18807 STIs were diagnosed and treated at the 14 STI clinics in fiscal year 2003–2004 (range 323–2784, median 1199). The economic cost of treating each STI varied 5-fold from Indian Rupees (INR) 225.5 (US$ 4.91) to INR 1201.5 (US$ 26.15) between 13 clinics, with one other clinic having a very high cost of INR 2478.5 (US$ 53.94). The average cost per STI treated for all 14 clinics combined was INR 729.5 (US$ 15.88). Personnel salaries made up 76.2% of the total cost. The number of STIs treated per doctor full-time equivalent and cost-efficiency for each STI treated had a significant direct non-linear relation (p < 0.001, R2 = 0.81; power function). With a multiple regression model, apart from the fixed costs, the incremental cost for each STI detected and cost of treatment was INR 55.57 (US$ 1.21) and for each follow-up visit was INR 3.75 (US$ 0.08). Based on estimates of optimal STI cases that could be handled without compromising quality by each doctor full-time equivalent available, it was projected that at 8 of the 14 clinics substantially more STI cases could be handled, which could increase the total STI cases treated at the 14 clinics combined by 38% at an additional cost of only 3.5% for service provision. Conclusion There is un-utilised capacity in the public sector STI clinics in this Indian state. Efforts to facilitate utilisation of this capacity would be useful, as this would enable more poor patients with STIs to be served at minimal additional cost, and would also reduce the cost per STI treated leading to more efficient use of public resources.

Objective: To assess the potential cost-effectiveness of short-course antiviral regimens to prevent mother-to-child transmission (MCT) of HIV in sub-Saharan Africa. Design: Cost-effectiveness analysis. Methods: No intervention was compared with three regimens of twice daily zidovudine and lamivudine: regimen A, starting at 36 weeks of gestation and continuing to 1 week postpartum; regimen B, from intrapartum through 1 week postpartum; and regimen C, intrapartum only. Model inputs were estimated from published and unpublished data. Absolute percentage reductions in HIV transmission extrapolated from zidovudine monotherapy trials were estimated at 12.4, 8.6 and 4.3% for regimens A, B, and C, respectively. Outcome measures were net costs to the public sector health-care system, cost per infection averted, and cost per disability-adjusted life-year (DALY) gained. Multiple sensitivity analyses were conducted. Results: Based on the hypothetical efficacy estimates, regimen C was the most cost-effective. For a cohort of 100 women with 15% HIV prevalence, net costs to the public sector health-care systems were estimated at US$ 3617 for regimen A, US$ 1667 for regimen B, and US$ 351 for regimen C. Regimen C had a cost of US$ 1129 per HIV infection averted and a cost of US$ 60 per DALY. Regimens B and A cost US$ 2680 and 5134 per infection averted and US$ 143 and 274 per DALY, respectively. Cost-effectiveness declined rapidly at efficacy below 10% or HIV prevalence below 7%. Results were very sensitive to antiviral drug costs. For example, at 20% of current prices, the cost per DALY for regimen A fell to US$ 64, and to about US$ 42 for regimens B and C. Conclusion: Antiviral therapy may be cost-effective compared with other health interventions if HIV prevalence is high, if clinical trials confirm estimated efficacies, and if drug prices are reduced.

The cost-effectiveness of public health cataract programs in low-income countries has been well documented. Equity, another important dimension of program quality which has received less attention is analyzed here by comparisons of surgical coverage rates for major sub-groups within the intended beneficiary population of the Nepal blindness program (NBP). Substantial differences in surgical coverage were found between males and females and between different age groups of the same gender. Among the cataract blind, the surgical coverage of males was 70% higher than that of females. For both genders, the cataract blind over 55 received proportionately fewer services than younger people blind from cataract. Blind males aged 45–54 had a 500% higher rate of surgical coverage than blind males over 65. Blind females aged 35–44 had nearly a 600% higher rate of surgical coverage than blind females over 65. There was wide variation in overall surgical coverage between geographic zones, but little variation by terrain type, an indicator of the logistical difficulties in delivery of services. Members of the two highest caste groupings had somewhat lower surgical coverage than members of lower castes. Program managers should consider developing methods to increase services to women and to those over 65. Reaching these populations will become increasingly important as those most readily served receive surgery and members of the under-served groups form a growing portion of the remaining cataract backlog.

Using data from the Lumbini Zonal Eye Care Program in Nepal, the authors estimated marginal costs, capital costs, and average recurring costs for a public health cataract program with and without donor agency overhead expenditures. Each estimate is useful for guiding decisions under certain conditions. Marginal costs are appropriate for short-term planning. Average in-country recurring cost figures are needed to project budgets for longer term program costs or major program expansion. A portion of donor agency overhead costs should be included if expansion requires more donor agency contributions. Marginal costs are estimated at US $3.01 per case. In-country recurring costs are about $13.91. Capital costs excluding hospital construction are an additional $2.42. Seva's USA administrative expenditures in support of the cataract component of the program add about another $5.38. Total costs were about $21.71 per case.

Background Consistent with observational studies, a randomized controlled intervention trial of adult male circumcision (MC) conducted in the general population in Orange Farm (OF) (Gauteng Province, South Africa) demonstrated a protective effect against HIV acquisition of 60%. The objective of this study is to present the first cost-effectiveness analysis of the use of MC as an intervention to reduce the spread of HIV in sub-Saharan Africa. Methods and Findings Cost-effectiveness was modeled for 1,000 MCs done within a general adult male population. Intervention costs included performing MC and treatment of adverse events. HIV prevalence was estimated from published estimates and incidence among susceptible subjects calculated assuming a steady-state epidemic. Effectiveness was defined as the number of HIV infections averted (HIA), which was estimated by dynamically projecting over 20 years the reduction in HIV incidence observed in the OF trial, including secondary transmission to women. Net savings were calculated with adjustment for the averted lifetime duration cost of HIV treatment. Sensitivity analyses examined the effects of input uncertainty and program coverage. All results were discounted to the present at 3% per year. For Gauteng Province, assuming full coverage of the MC intervention, with a 2005 adult male prevalence of 25.6%, 1,000 circumcisions would avert an estimated 308 (80% CI 189–428) infections over 20 years. The cost is $181 (80% CI $117–$306) per HIA, and net savings are $2.4 million (80% CI $1.3 million to $3.6 million). Cost-effectiveness is sensitive to the costs of MC and of averted HIV treatment, the protective effect of MC, and HIV prevalence. With an HIV prevalence of 8.4%, the cost per HIA is $551 (80% CI $344–$1,071) and net savings are $753,000 (80% CI $0.3 million to $1.2 million). Cost-effectiveness improves by less than 10% when MC intervention coverage is 50% of full coverage. Conclusions In settings in sub-Saharan Africa with high or moderate HIV prevalence among the general population, adult MC is likely to be a cost-effective HIV prevention strategy, even when it has a low coverage. MC generates large net savings after adjustment for averted HIV medical costs., Based on data from a trial of adult male circumcision to reduce the spread of HIV, a modeling study shows this intervention to be a cost-effective strategy., Editors' Summary Background. Preventing the spread of HIV is an enormous challenge of great importance worldwide. In 2005, HIV/AIDS was responsible for around 3 million deaths, of which approximately one-third were in sub-Saharan Africa. HIV is spread from one person to another in three main ways: through unprotected sex; through contaminated blood or blood products (for example when shared needles are used); and from mother to child (during pregnancy, labor, and breastfeeding). Many strategies for preventing HIV focus on reducing risky behaviors. For example, condoms used correctly are effective at preventing HIV infection, and many countries now aim to promote condom use, together with other approaches that will reduce the risk of getting HIV. However, it is unlikely that strategies involving large-scale changes in behavior will ever be completely effective. Recently, much attention has focused on the possibility that circumcision might provide men with some protection against getting HIV. The results of a trial carried out in South Africa, the ANRS 1265 trial (published in PLoS Medicine in October 2005) seem to support this theory, and additional trials are being carried out in Kenya and Uganda. The results from these further trials will help determine whether, and to what extent, the effect of circumcision seen in the South African trial is true more generally. Why Was This Study Done? The investigators who had carried out the South African circumcision trial wanted to find out how the economic aspects of this prevention strategy would compare with other strategies for prevention of HIV. Specifically, they wanted to know how much male circumcision would cost overall, per HIV infection prevented, as compared with the cost of other strategies. They also wanted to understand whether circumcision would be “cost-saving.” In other words, would the cost of performing the operation (together with the cost of treating any adverse effects suffered by the men who were circumcised) be offset by the costs of treatment for HIV infections that the intervention prevented? Getting this information is crucial before health policy makers can decide what strategies for preventing HIV are most appropriate for their country. What Did the Researchers Do and Find? In this study, the researchers carried out a set of mathematical calculations, using the results from the ANRS 1265 trial, together with some other data and background assumptions. Their model was based on a hypothetical group of 1,000 men, all of whom would be circumcised. The researchers calculated that in such a hypothetical group, the cost of providing male circumcision, per HIV infection prevented, would be around $180. Overall, this procedure seemed to be cost-saving when the cost of HIV treatment was also factored in; around $2.4 million would be saved for the 1,000 men circumcised. What Do These Findings Mean? These results suggest that, assuming the results of the South African trial are generally true, male circumcision would reduce the cost of health care in South Africa, mainly through savings on the cost of HIV treatment. The overall cost of male circumcision, per HIV infection prevented, is reasonable as compared to the costs of other strategies for prevention of HIV. There would also be implications for HIV prevention programs in other African countries. However, these estimates are based on the data from one trial only. The World Health Organization does not currently recommend the promotion of male circumcision for prevention of HIV. Meanwhile, proven strategies for preventing HIV exist, and more information is available from the links below. Additional Information.

Background Female sex workers and their clients play a prominent role in the HIV epidemic in India. Systematic data on the outputs, cost and efficiency for HIV prevention programmes for female sex workers in India are not readily available to understand programme functioning and guide efficient use of resources. Methods Detailed output and cost data for the 2002–2003 fiscal year were obtained using standardised methods at 15 HIV prevention programmes for female sex worker in the state of Andhra Pradesh in southern India. The services provided and their relation to the total and unit economic costs were analysed using regression techniques. The trends for the number of sex workers provided services by the programmes since inception up to fiscal year 2004–2005 were examined. Results The 15 programmes provided services to 33941 sex workers in fiscal year 2002–2003 (range 803–6379, median 1970). Of the total number of contacts with sex workers, 41.6% were by peer educators and 58.4% by other programme staff. The number of sex worker contacts in a year by peer educators varied 74-fold across programmes as compared with a 2.7-fold variation in sex worker contacts by other programme staff. The annual economic cost of providing services to a sex worker varied 6-fold between programmes from Indian Rupees (INR) 221.8 (US$ 4.58) to INR 1369 (US$ 28.29) with a median of INR 660.9 (US$ 13.66) and mean of INR 517.8 (US$ 10.70). Personnel salaries made up 34.7% of the total cost, and recurrent goods made up 38.4% of which 82.1% was for condoms. The cost per sex worker provided services had a significant inverse relation with the number of sex workers provided services by a programme (p < 0.001, R2 = 0.75; power function). There was no correlation between the full time equivalents of programme staff and the number of sex workers provided services by the programmes, but there was a modest inverse correlation between the number of sex workers served and the average time spent with each sex worker in the year adjusted for the full-time equivalents of programme staff (p = 0.011, R2 = 0.40; exponential function). The average number of sex workers provided services annually by the first batch of 7 programmes started in early 1999 plateaued after the fourth fiscal year to 3500, whereas the 8 second-batch programmes started in late 2000 reached an average of 2000 sex workers in 2004–2005 with an increasing trend up to this fourth fiscal year. Conclusion The HIV prevention efforts in this Indian state would benefit from standardisation of the highly variable services provided by peer educators, who form an important part of the sex worker programmes. The cost per sex worker served decreases with increasing number of sex workers served annually, but this has to be weighed against an associated modest trend of decrease in time spent with each sex worker in some programmes.

Background Adult male circumcision (MC) services in Kenya are provided through both horizontal and vertical programs, and via facility-based, mobile and outreach service delivery. This study assesses the costs and composition of unit costs for each program approach and service delivery mode and assess the cost-effectiveness of each. Methods This study was conducted on the unit costs of adult MC delivery in 222 purposively-selected MC delivery sites in Nyanza Province, Kenya from November 2008 through April 2010 using program data from the AIDS, Population, and Health Integrated Assistance Project II (APHIA II) and from the Nyanza Reproductive Health Society (NRHS). The former program can be characterized as horizontal or integrated; the latter as ‘diagonal’; containing both horizontal and vertical elements. Expenditure and services data were collected from project financial and monitoring documents and via discussions with program officials. In addition, per-case, direct service delivery costs were calculated using time and motion observations of 246 adult MC procedures performed during May and June, 2010. We calculated the cost per HIV infections averted for each of the service delivery modalities. Results Unit cost per adult MC was $38.62 and $44.24 for APHIA II and NRHS respectively, ranging from $29.32 (APHIA II mobile) to $46.20 (NRHS outreach/mobile). Unit costs at base facilities was similar for the two approaches. Time and motion data revealed that the opportunity cost of the elapsed time between the arrival of the surgical team and the time the first MC procedure begins varies between $2.08 and $6.27 per case. The cost per HIV infection (HIA) averted ranged from $117.29 for mobile service via the horizontal APHIA-II program to $184.84 per HIA for the diagonal NRHS program. Conclusions This study provides evidence for the similar efficiency of a horizontal approach (APHIA II) and a combination of horizontal and vertical approaches (NRHS) to support scale-up of adult MC services in Nyanza. Differences in unit cost are modest, not consistently in the same direction, and largely explained by differences in compensation levels.
