Objective: To determine the cost-effectiveness of a worksite-based naturopathic (individualized lifestyle counseling and nutritional medicine) approach to primary prevention of cardiovascular disease (CVD)., Methods: Economic evaluation alongside a pragmatic, multi-worksite, randomized controlled trial comparing enhanced usual care (EUC; usual care plus biometric screening) to the addition of a naturopathic approach to CVD prevention (NC+EUC)., Results: After 1 year, NC+EUC resulted in a net decrease of 3.3 (confidence interval: 1.7 to 4.8) percentage points in 10-year CVD event risk (number needed to treat = 30). These risk reductions came with average net study-year savings of $1138 in societal costs and $1187 in employer costs. There was no change in quality-adjusted life years across the study year., Conclusions: A naturopathic approach to CVD primary prevention significantly reduced CVD risk over usual care plus biometric screening and reduced costs to society and employers in this multi-worksite-based study. Trial Registration clinicaltrials.gov Identifier: NCT00718796.

Aims: To assess the impact on healthcare resource utilization, costs, and quality of life over 15 years from 5 years of statin use in men without a history of myocardial infarction in the West of Scotland Coronary Prevention Study (WOSCOPS)., Methods: Six thousand five hundred and ninety-five participants aged 45-54 years were randomized to 5 years treatment with pravastatin (40 mg) or placebo. Linkage to routinely collected health records extended follow-up for secondary healthcare resource utilization to 15 years. The following new results are reported: cause-specific first and recurrent cardiovascular hospital admissions including myocardial infarction, heart failure, stroke, coronary revascularization and angiography; non-cardiovascular hospitalization; days in hospital; quality-adjusted life years (QALYs); costs of pravastatin treatment, treatment safety monitoring, and hospital admissions., Results: Five years treatment of 1000 patients with pravastatin (40 mg/day) saved the NHS £710 000 (P < 0.001), including the cost of pravastatin and lipid and safety monitoring, and gained 136 QALYs (P = 0.017) over the 15-year period. Benefits per 1000 subjects, attributable to prevention of cardiovascular events, included 163 fewer admissions and a saving of 1836 days in hospital, with fewer admissions for myocardial infarction, stroke, heart failure and coronary revascularization. There was no excess in non-cardiovascular admissions or costs (or in admissions associated with diabetes or its complications) and no evidence of heterogeneity of effect over sub-groups defined by baseline cardiovascular risk., Conclusion: Five years' primary prevention treatment of middle-aged men with a statin significantly reduces healthcare resource utilization, is cost saving, and increases QALYs. Treatment of even younger, lower risk individuals is likely to be cost-effective.

Combination pills containing aspirin, multiple blood pressure (BP) lowering drugs, and a statin have demonstrated safety, substantial risk factor reductions, and improved medication adherence in the prevention of cardiovascular disease (CVD). The individual medications in combination pills are already recommended for use together in secondary CVD prevention. Therefore, current information on their pharmacokinetics, impact on the risk factors, and tolerability should be sufficient to persuade regulators and clinicians to use fixed-dose combination pills in high-risk individuals, such as in secondary prevention. Long-term use of these medicines, in a polypill or otherwise, is expected to reduce CVD risk by at least 50-60% in such groups. This risk reduction needs confirmation in prospective randomized trials for populations for whom concomitant use of the medications is not currently recommended (e.g. primary prevention). Given their additive benefits, the combined estimated relative risk reduction (RRR) in CVD from both lifestyle modification and a combination pill is expected to be 70-80%. The first of several barriers to the widespread use of combination therapy in CVD prevention is physician reluctance to use combination pills. This reluctance may originate from the belief that lifestyle modification should take precedence, and that medications should be introduced one drug at a time, instead of regarding combination pills and lifestyle modification as complementary and additive. Second, widespread availability of combination pills is also impeded by the reluctance of large pharmaceutical companies to invest in development of novel co-formulations of generic (or 'mature') drugs. A business model based on 'mass approaches' to drug production, packaging, marketing, and distribution could make the combination pill available at an affordable price, while at the same time providing a viable profit for the manufacturers. A third barrier is regulatory approval for novel multidrug combination pills, as there are few precedents for the approval of combination products with four or more components for CVD. Acceptance of combination therapy in other settings suggests that with concerted efforts by academics, international health agencies, research funding bodies, governments, regulators, and pharmaceutical manufacturers, combination pills for prevention of CVD in those with disease or at high risk (e.g. those with multiple risk factors) can be made available worldwide at affordable prices. It is anticipated that widespread use of combination pills with lifestyle modifications can lead to substantial risk reductions (as much as an 80% estimated RRR) in CVD. Heath care systems need to deploy these strategies widely, effectively, and efficiently. If implemented, these strategies could avoid several millions of fatal and non-fatal CVD events every year worldwide.

Background: Although randomized trials have shown the beneficial effect on survival of an implantable cardioverter defibrillator (ICD) as primary prevention therapy in selected patients, data concerning the cost-effectiveness in routine clinical practice remain scarce. Accordingly, the purpose of this study was to assess the cost-effectiveness of primary prevention ICD implantation in the real world., Methods: Patients receiving primary prevention single-chamber or dual-chamber ICD implantation at the Leiden University Medical Center were included in the study. Using a Markov model, lifetime cost, life years (LYs), and gained quality-adjusted life years (QALYs) were estimated for device recipients and control patients. Data on mortality, complication rates, and device longevity were retrieved from our center and entered into the Markov model. To account for model assumptions, one-way deterministic and probabilistic sensitivity analyses were performed. Importantly, calculations for the estimated incremental cost-effectiveness rate (ICER) per QALY gained are based on several numbers of assumptions, and accordingly findings may have over- or underestimated the cost-effectiveness of ICD therapy., Results: Primary prevention ICD implantation adds an estimated mean of 2.07 LYs and 1.73 QALYs. Increased lifetime cost for single-chamber and dual-chamber ICD recipients were estimated at €60,788 and €64,216, respectively. This resulted for single-chamber ICD recipients, in an estimated ICER of €35,154 per QALY gained. In dual-chamber ICD recipients, an estimated ICER of €37,111 per QALY gained was calculated. According to the probabilistic sensitivity analysis, estimated cost per QALY gained are €35,837 (95% confidence interval [CI]: €28,368-€44,460) for single-chamber and €37,756 (95% CI: €29,055-€46,050) for dual-chamber ICDs., Conclusions: On the basis of data and detailed costs, derived from routine clinical practice, ICD therapy in selected patients with a reduced left ventricular ejection fraction appears to be cost-effective., (©2013, The Authors.

Objective: Evaluate the cost-effectiveness of primary vs secondary prophylaxis (PP vs SP) with pegfilgrastim to reduce the risk of febrile neutropenia (FN) in Non-Hodgkin's Lymphoma (NHL) patients receiving myelosuppressive chemotherapy from a US payer perspective., Methods: A Markov model was used to compare PP vs SP with pegfilgrastim in a cohort of patients receiving six cycles of cyclophosphamide, vincristine, doxorubicin, and prednisone (CHOP) or CHOP plus rituximab (CHOP-R) chemotherapy. Model inputs, including efficacy of pegfilgrastim in reducing risk of FN and costs, were estimated from publicly available sources and peer-reviewed publications. Incremental cost-effectiveness was evaluated in terms of net cost per life-year saved (LYS), per quality-adjusted life-year (QALY) gained, and per FN event avoided over a lifetime horizon. Deterministic and probabilistic analyses were performed to assess sensitivity and robustness of results., Results: Lifetime costs for PP were $5000 greater than for SP; however, PP was associated with fewer FN events and more LYs and QALYs gained vs SP. Incremental cost-effectiveness ratios (ICERs) for PP vs SP for CHOP were $13,400 per FN event avoided, $29,500 per QALY gained, and $25,800 per LYS. CHOP-R results were similar ($15,000 per FN event avoided, $33,000 per QALY gained, and $28,900 per LYS). Results were most sensitive to baseline FN risk, cost per FN episode, and odds ratio for reduced relative dose intensity due to prior FN event. PP was cost-effective vs SP in 85% of simulations at a $50,000 per QALY threshold., Limitations: In the absence of NHL-specific data, estimates for pegfilgrastim efficacy and relative risk reduction of FN were based on available data for neoadjuvant TAC in patients with breast cancer. Baseline risks of FN for CHOP and CHOP-R were assumed to be equivalent., Conclusions: PP with pegfilgrastim is cost-effective compared to SP with pegfilgrastim in NHL patients receiving CHOP or CHOP-R.

Background: Early detection and treatment of cardiovascular disease (CVD) risk factors produces significant clinical benefits, but no consensus exists on optimal screening algorithms. This study aimed to evaluate the comparative and cost-effectiveness of staged laboratory-based and non-laboratory-based total CVD risk assessment., Methods and Results: We used receiver operating characteristic curve and cost-effectiveness modeling methods to compare strategies with and without laboratory components and used single-stage and multistage algorithms, including approaches based on Framingham risk scores (laboratory-based assessments for all individuals). Analyses were conducted using data from 5998 adults in the Third National Health and Nutrition Examination Survey without history of CVD using 10-year CVD death as the main outcome. A microsimulation model projected lifetime costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios for 60 Framingham-based, non-laboratory-based, and staged screening approaches. Across strategies, the area under the receiver operating characteristic curve was 0.774 to 0.780 in men and 0.812 to 0.834 in women. There were no statistically significant differences in area under the receiver operating characteristic curve between multistage and Framingham-based approaches. In cost-effectiveness analyses, multistage strategies had incremental cost-effectiveness ratios of $52,000/QALY and $83,000/QALY for men and women, respectively. Single-stage/Framingham-based strategies were dominated (higher cost and lower QALYs) or had unattractive incremental cost-effectiveness ratios (>$300,000/QALY) compared with single-stage/non-laboratory-based and multistage approaches., Conclusions: Non-laboratory-based CVD risk assessment can be useful in primary CVD prevention as a substitute for laboratory-based assessments or as the initial component of a multistage approach. Cost-effective multistage screening strategies could avoid 25% to 75% of laboratory testing used in CVD risk screening with predictive power comparable with Framingham risks.

CT colonography has been shown to be an effective method to screen for colorectal cancer. However, at present, full endorsement and reimbursement for screening CT colonography, particularly by the US Preventive Services Task Force and CMS, respectively, are absent, so this screening option is infrequently used, and optical colonoscopy remains the de facto standard screening option. The authors summarize the past accomplishments that led to the current state of reimbursement and outline the remaining challenges and road to full acceptance and reimbursement of screening CT colonography nationally., (Copyright © 2013 American College of Radiology.

Poverty is a critical social determinant of health. A particular approach toward mitigating inequitable access to health services in Kenya has been through a community-based distribution program implemented by the Safe Water and AIDS Project (SWAP) that has achieved modest uptake of public health interventions. To explore reasons for modest uptake, we asked program participants about child health problems, daily tasks, household expenditures, and services needed by their communities. Respondents identified child health problems consistent with health data and reported daily tasks, expenses, and needed services that were more related to basic needs of life other than health. These findings highlight the challenges of implementing potentially self-sustaining preventive interventions at scale in poor populations in the developing world.

With economic growth in Asia, cancer has become increasingly prominent as a major health problem. However, discrepancies in infrastructure, economics, and development exist within and between Asian countries. We assess means of primary and secondary prevention for cervical, breast, colorectal, and hepatocellular cancer, and offer recommendations according to resource levels. Primary prevention by health education, lifestyle modification, and avoidance of risk factors should be made available at all resource levels. When resources allow, human papillomavirus and hepatitis B vaccinations should be given to reduce the risk of cervical and hepatocellular cancer, and genetic testing should be offered to detect increased susceptibility to colorectal and breast cancer. Secondary prevention by effective yet affordable screening for precancerous lesions or by early detection of cancer should be offered, followed by appropriate treatment., (Copyright © 2013 Elsevier Ltd.

Background: Recent data suggest that aspirin may be effective for reducing cancer mortality., Objective: To examine whether including a cancer mortality-reducing effect influences which men would benefit from aspirin for primary prevention., Design: We modified our existing Markov model that examines the effects of aspirin among middle-aged men with no previous history of cardiovascular disease or diabetes. For our base case scenario of 45-year-old men, we examined costs and life-years for men taking aspirin for 10 years compared with men who were not taking aspirin over those 10 years; after 10 years, we equalized treatment and followed the cohort until death. We compared our results depending on whether or not we included a 22 % relative reduction in cancer mortality, based on a recent meta-analysis. We discounted costs and benefits at 3 % and employed a third party payer perspective., Main Measure: Cost per quality-adjusted life year (QALY) gained., Key Results: When no effect on cancer mortality was included, aspirin had a cost per QALY gained of $22,492 at 5 % 10-year coronary heart disease (CHD) risk; at 2.5 % risk or below, no treatment was favored. When we included a reduction in cancer mortality, aspirin became cost-effective for men at 2.5 % risk as well (cost per QALY, $43,342). Results were somewhat sensitive to utility of taking aspirin daily; risk of death after myocardial infarction; and effects of aspirin on stroke, myocardial infarction, and sudden death. However, aspirin remained cost-saving or cost-effective (< $50,000 per QALY) in probabilistic analyses (59 % with no cancer effect included; 96 % with cancer effect) for men at 5 % risk., Conclusions: Including an effect of aspirin on cancer mortality influences the threshold for prescribing aspirin for primary prevention in men. If such an effect is real, many middle-aged men at low cardiovascular risk would become candidates for regular aspirin use.

Despite the benefits in reducing the risk of stroke, primary prevention is not well translated into practice. We sought to evaluate patient compliance with guidelines and the cost of primary stroke prevention in southwest China. We consecutively enrolled 305 patients with headaches and/or dizziness who were at high risk of stroke from our hospital. We retrospectively obtained their information, including the extent of their knowledge of stroke risk factors, adherence to guidelines, medications taken, and costs of primary prevention for stroke within the past year. Only 45.9% of patients had any knowledge of primary prevention, and only 17.0% had completely followed guidelines. Moreover, 79.0% of the patients were using medications, but only 39.3% took their medication as recommended. In patients who took medication, 89.6% were prescribed by physicians. The annual costs of primary prevention were estimated to be US$517.8 per capita, which included direct medical costs (US$435.4), direct non-medical costs (US$18.1), and indirect costs (US$64.3). Costs in the hypertension group were less than those reported by a similar international study. Although our population sample may not be representative of the population at high risk of stroke in China, it is appropriate for the evaluation of our primary prevention system. Primary prevention for stroke in southwest China is very challenging, with few medical resource investments. There is a current urgency to improve patient knowledge of primary prevention, which would bridge the gaps between guidelines and practice and increase medical resource investments., (Copyright © 2013 Elsevier Ltd.

Lower leg ulcers is the most common form of ulceration of the lower extremities. The prevalence of leg ulcer varies among studies from 0.1% to 0.6%. In the majority of studies, 1% of the population develop leg ulcer at least once in lifetime. The prevalence is higher in elderly people. There are several hypotheses used to explain the pathophysiological steps leading from the popliteal venous hypertension in value. Currently, the treatment of leg ulcer relies on due knowledge of ulcer pathophysiology and making an accurate diagnosis. Venous disease has a significant impact on quality of life and work productivity. In addition, costs associated with the prevention and treatment of lower leg ulcers are significant.

Aims: To determine the long-term costs of extending device longevity in four patient populations requiring a single-chamber implantable cardioverter-defibrillator (ICD) or requiring cardiac resynchronization therapy with defibrillation (CRT-D) device over a 15-year time window., Methods and Results: We considered patient populations with an accepted indication for a single-chamber ICD for prevention of sudden cardiac death in the context of preserved (Population A) or impaired (Population B) left ventricular function; or with indication for a CRT-D device in the context of heart failure in New York Heart Association class II (Population C) or III (Population D). Expected patient survival and a cost analysis, including the cost of complications, was undertaken from a hospital perspective. Extended device longevity of 5 vs. 9 years for ICDs (Populations A and B); 4 vs. 7 years for CRT-Ds (Populations C and D) were considered. Over a 15-year time horizon, total, yearly, and per diem savings, per patient, from extending ICD longevity to 9 years were €10 926.91, €728.46, and €1.99 for Population A, and €7661.32, €510.75, and €1.40 for Population B. Total, yearly, and per diem savings from extending CRT-D longevity to 7 years were €13 630.38, €908.69, and €2.49 for Population C, and €10 968.29, €731.22, and €2.00 for Population D. Avoidance of a generator replacement amounted up to 46.6-62.5% of the saving., Conclusion: Extending device longevity has an important effect on the long-term cost of device therapy, both for ICD and CRT-D. This has important implications for device choice.

Questions of social justice and health-care costs are some of the concerns of society. The cost caused by cardiovascular diseases can have an enormous impact, and it is important to know what patients think about illness costs when they are hospitalized. Two interviews were realized in a longitudinal study, in a sample of 106 patients submitted to expensive techniques in Cardiology (Portugal), to understand the patients' perception about the health costs and behavior changes based on awareness. We can conclude that cardiovascular diseases are a global phenomenon that generally affects all social groups. From those interviewed, 83% of the patients agree about getting information concerning the treatments and intervention costs during hospitalization because the information about costs can bring the necessary tools for improvement in patients and health resources; 70.8% of the patients say that this information could bring awareness to the patient's life, enhancing responsibility and personal autonomy.

Background: Febrile neutropenia is a serious toxicity of cancer chemotherapy that is usually treated in hospital. We assessed the cost-effectiveness of filgrastim and pegfilgrastim as primary prophylaxis against febrile neutropenia in diffuse large B-cell lymphoma (DLBCL) patients undergoing chemotherapy., Methods: We used a Markov model that followed patients through induction chemotherapy to compare the three prophylaxis strategies: 1) no primary prophylaxis against febrile neutropenia; 2) primary prophylaxis with 10 days of filgrastim therapy; and 3) primary prophylaxis with a single dose of pegfilgrastim. The target population was a hypothetical cohort of 64-year-old men and women with DLBCL. Data sources included published literature and current clinical practice. The analysis was conducted from a publicly funded health-care system perspective. The main outcome measures included costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs)., Results: In the base-case analysis, costs associated with no primary prophylaxis, primary prophylaxis with 10 days of filgrastim, and primary prophylaxis with pegfilgrastim were CaD $7314, CaD $13947, and CaD $16290, respectively. The QALYs associated with the three strategies were 0.2004, 0.2015, and 0.2024, respectively. The ICER for the filgrastim vs no primary prophylaxis strategy was CaD $5796000 per QALY. The ICER for the pegfilgrastim vs filgrastim primary prophylaxis strategy was CaD $2611000 per QALY. All one-way sensitivity analyses yielded ICERs greater than CaD $400000 per QALY. Cost-effectiveness acceptability curves show that 20.0% of iterations are cost-effective at a willingness-to-pay threshold of CaD $1595000 for the filgrastim strategy and CaD $561000 for the pegfilgrastim strategy., Conclusions: Primary prophylaxis against febrile neutropenia with either filgrastim or pegfilgrastim is not cost-effective in DLBCL patients.

Statins are widely used in the evidence-based lowering of cardiovascular disease (CVD) risk. The use of these drugs for secondary prevention of CVD is well founded, but their expanding use in primary prevention--in individuals without documented CVD--has raised some concerns. Firstly, evidence suggests that, in primary prevention, statins substantially decrease CVD morbidity, but only moderately reduce CVD mortality. Secondly, long-term statin use might cause adverse effects, such as incident diabetes mellitus. Thirdly, the cost-effectiveness of such a strategy is unclear, and has to be balanced against the risk of 'overmedicating' the general population. Data clearly support the use of statins for primary prevention in high-risk individuals, in whom the strategy is cost-effective and the benefits exceed the risks. Whether primary prevention is beneficial in individuals at low or moderate risk is not certain. Therefore, the prescription of statins for primary prevention should be individualized on the basis of clinical judgment, particularly for low-risk individuals. In appropriately selected individuals, statins should also be used for primary prevention of ischaemic stroke and transient ischaemic attack.

In regional Australia "communities of place," defined as bounded geographic locations with a local society, undertake community-wide primary prevention programs. In helping to prevent chronic illness, communities provide valuable resources to the health system. To understand the role of community-health sector partnerships for primary prevention and the community contextual factors that affect them, we studied eight partnerships. We used an embedded multiple case study design and collected data through interviews, nonparticipant observation, and document analysis. These data were analyzed using a typology of community-health sector partnerships and community interaction theory to frame the key community contextual factors that affected partnerships. The dominant factor affecting all partnerships was the presence of a collective commitment that communities brought to making the community a better place through developing health. We call this a communitarian approach. Additional research to investigate factors influencing a communitarian approach and the role it plays in partnerships is required.

In France, as in many countries, tackling social inequalities in health is a public health priority. However, primary prevention may sometimes contribute to increase such inequalities. This article aims to illustrate this point, considering the cases of smoking and obesity. The implicit hypotheses of prevention regarding its targets are discussed, as well as its stigmatization effects. On the one hand, prevention can increase the social differentiation of risky behaviors, as it is more effective among wealthier and more educated people. On the other hand, prevention policies intending to increase either the financial or the symbolic cost of risky behaviors may also increase social inequalities. Primary prevention needs more reflexivity regarding its potential unintended and deleterious side effects., (Copyright © 2013 Elsevier Masson SAS. All rights reserved.)

Prevention of disease is often difficult to put into practice. Among the obstacles: the success of prevention is invisible, lacks drama, often requires persistent behavior change, and may be long delayed; statistical lives have little emotional effect, and benefits often do not accrue to the payer; avoidable harm is accepted as normal, preventive advice may be inconsistent, and bias against errors of commission may deter action; prevention is expected to produce a net financial return, whereas treatment is expected only to be worth its cost; and commercial interests as well as personal, religious, or cultural beliefs may conflict with disease prevention. Six strategies can help overcome these obstacles: (1) Pay for preventive services. (2) Make prevention financially rewarding for individuals and families. (3) Involve employers to promote health in the workplace and provide incentives to employees to maintain healthy practices. (4) Reengineer products and systems to make prevention simpler, lower in cost, and less dependent on individual action. (5) Use policy to reinforce choices that favor prevention. (6) Use multiple media channels to educate, elicit health-promoting behavior, and strengthen healthy habits. Prevention of disease will succeed over time insofar as it can be embedded in a culture of health.

Hemodialysis central venous catheter (CVC) use is associated with the highest morbidity, mortality, and cost of all types of hemodialysis vascular access. CVC-related infection drives much of the cost associated with CVC use. The magnitude of the cost associated with CVC-related infection varies depending on the type and severity of that infection; however, estimates of the total direct and indirect costs associated with hospitalizations due to hemodialysis CVC-related infections range from 17,000 USD to 32,000 USD per episode. Thus, it is critically important, to not only have effective strategies to limit CVC-related infection but also evaluate whether these strategies are an efficient use of resources. Prophylactic strategies can be considered economically efficient only if the value of its implementation and the corresponding drop in infection rate offer greater value than standard care. The optimal CVC-related infection prophylaxis strategy should work to limit infection risk with minimal risk, inconvenience, and discomfort to the patient, and at minimal cost. The aim of this review was to examine the clinical and economic impact of some commonly described interventions used for CVC infection prophylaxis., (© 2013 Wiley Periodicals, Inc.)

Background: Cardiovascular disease is a major cause of mortality and morbidity and its prevalence is set to increase. While the benefits of medical and lifestyle interventions are established, the effectiveness of interventions which seek to improve the way preventive care is delivered in general practice is less so. The aim was to study and to compare the effectiveness of 2 intervention programmes for reducing cardiovascular risk factors within general practice., Methods: A randomised controlled trial was conducted in Belgium between 2007-2010 with 314 highly educated and mainly healthy professionals allocated to a medical (MP) or a medical + lifestyle (MLP) programme. The MP consisted of medical assessments (screening and follow-up) and the MLP added a tailored lifestyle change programme (web-based and individual coaching) to the MP. Primary outcomes were total cholesterol, blood pressure, and body mass index (BMI). The secondary outcomes were smoking status, fitness-score, and total cardiovascular risk., Results: The mean age was 41 years, 95 (32%) participants were female, 7 had a personal cardiovascular event in their medical history and 3 had diabetes. There were no significant differences found between MP and MLP in primary or secondary outcomes. In both study conditions decreases of cholesterol, systolic blood pressure, and diastolic blood pressure were found. Unfavourable increases were found for BMI (p < .05). A significant decrease of the overall cardiovascular risk was reported (p < .001)., Conclusions: Both interventions are effective in reducing cardiovascular risk. In our population the combined medical and lifestyle programme was not superior to the medical programme., Trial Registration: ISRCTN23940498.

Unlabelled: To test the hypothesis that care typology-being complex and highly unpredictable versus being clear-cut and highly predictable-guides healthcare payment preferences of physicians, policy makers, healthcare executives, and researchers. We collected survey data from 942 stakeholders across Canada, Europe, Oceania, and the United States. A total of 48 international societies invited their members to participate in our study., Study Design: Cross-sectional analysis of stakeholder survey data linked to four scenarios of care typology: primary prevention, trial-and-error care, standard care and network care., Principal Findings: We identified two "extremes": (1) dominant preferences of physicians, who embraced fee for service (FFS), even when this precludes the advantages of other payment systems associated with a minimal risk of harm (OR 1.85 for primary prevention; OR 1.89 for standard care, compared to non-physicians); and (2) the dominant preferences of healthcare executives and researchers, who supported quality bonus or adjustment (OR 1.92) and capitation (OR 2.05), respectively, even when these could cause harm., Conclusions: Based on exploratory findings, we can cautiously state that payment reform will prove to be difficult as long as physicians, healthcare executives, and researchers misalign payment systems with the nature of care. Replication studies are needed to (dis)confirm our findings within representative subsamples per area and stakeholder group., (Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.)

Purpose: The 2012 American Urological Association (AUA) Clinical Effectiveness Protocols for Imaging in the Management of Ureteral Calculous Disease recommends routine postoperative imaging after ureteroscopy. We evaluated the cost-effectiveness of routine postoperative imaging after ureteroscopy., Materials and Methods: We searched the literature to determine the risk of complications after routine ureteroscopy for stones, including the incidence of postoperative pain, stricture and silent obstruction. Sequelae of renal loss due to undiagnosed silent obstruction may include chronic kidney disease, end stage renal disease and cardiovascular disease. Imaging and procedure costs were obtained from Medicare reimbursement rates and the literature. The costs and prevalence of lifetime complications associated with silent loss of 1 kidney were obtained from the renal donor transplant literature. A decision tree was constructed to calculate the cost of a strategy of routinely imaging all patients after ureteroscopy vs selective imaging based on postoperative pain. We performed 1-way and 2-way sensitivity analyses., Results: The average cost per patient of a strategy of routine imaging after ureteroscopy in all patients was $5,326 vs $5,196 for a strategy of selective imaging based on postoperative pain. Assuming a 2% rate of silent obstruction, the cost per kidney saved would be $6,262., Conclusions: While routine postoperative imaging carries a $130 per patient incrementally higher cost over that of a strategy of selective imaging in patients with postoperative pain, preventing renal loss and its attendant morbidity justifies the additional modest cost., (Copyright © 2013 American Urological Association Education and Research, Inc.

Objectives: This study sought to assess the impact of baseline heart failure (HF) burden on survival with primary implantable cardioverter-defibrillator (ICD) among Medicare recipients., Background: Survival after primary ICD implantation may differ between trial and Medicare populations., Methods: Linking data from the CMS (Centers for Medicare and Medicaid Services) ICD registry and the Medicare files (2005 to 2009), we identified primary ICD recipients age ≥66 years with ejection fraction ≤35%. Number of previous HF hospitalizations (prev-HF-hosp) and length of hospitalization prior to implantation were used to define HF burden. Crude all-cause mortality was estimated. Adjusted hazard ratios (HR) were derived from Cox models., Results: Of 66,974 ICD recipients (73% men, 88% white, mean age 75 years), 11,876 died (average follow-up = 1.4 years), with 3-year mortality of 31%. Among patients with no prev-HF-hosp, 3-year mortality was 27% compared with 63% in those with ≥3 prev-HF-hosp (adjusted HR: 1.8). Among patients with same-day implantation, 3-year mortality was 25% compared with 53% in those with >1-week hospitalization days prior to implantation (adjusted HR: 1.9). Mortality at 3-year follow-up among the 31,685 ICD recipients with no prev-HF-hosp and same-day implantation (low HF burden) was similar to that in trials (22%)., Conclusions: Nearly one-third of Medicare ICD recipients died within 3 years, reflecting a population with more advanced age and disease than seen in trial populations for primary prevention ICD. Nearly one-half of Medicare recipients had a low HF burden and had a survival similar to trial ICD recipients. Future research is warranted to understand the effectiveness of primary ICD implantation among Medicare beneficiaries with heavy HF burdens., (Copyright © 2013 American College of Cardiology Foundation.

Background: Acute rheumatic fever and subsequent rheumatic heart disease remain significant in developing countries. We describe a cost-effective analysis of 7 strategies for the primary prevention of acute rheumatic fever and rheumatic heart disease in children presenting with pharyngitis in urban primary care clinics in South Africa., Methods and Results: We used a Markov model to assess the cost-effectiveness of treatment with intramuscular penicillin using each of the following strategies: (1) empirical (treat all); (2) positive throat culture (culture all); (3) clinical decision rule (CDR) score ≥2 (CDR 2+); (4) CDR score ≥3 (CDR 3+); (5) treating those with a CDR score ≥2 plus those with CDR score <2 and positive cultures (CDR 2+, culture CDR negatives); (6) treating those with a CDR score ≥3 plus those with CDR score <3 and positive cultures (CDR 3+, culture CDR negatives); and (7) treat none. The strategies ranked in order from lowest cost were treat all ($11.19 per child), CDR 2+ ($11.20); the CDR 3+ ($13.00); CDR 2+, culture CDR negatives ($16.42); CDR 3+, culture CDR negatives ($23.89); and culture all ($27.21). The CDR 2+ is the preferred strategy at less than $150/quality-adjusted life year compared with the treat all strategy. A strategy of culturing all children compared with the CDR 2+ strategy costs more than $125 000/quality-adjusted life year gained., Conclusions: Treating all children presenting with pharyngitis in urban primary care clinics in South Africa with intramuscular penicillin is the least costly. A strategy of using a clinical decision rule without culturing is overall the preferred strategy. A strategy of culturing all children may be prohibitively expensive.

An alarming proportion of incident human immunodeficiency virus (HIV) infections worldwide occur in youth. In the United States, 69% of all new infections among youth occurred in young men who have sex with men (YMSM). Recent studies show the promise of preexposure prophylaxis (PrEP) for preventing HIV infection, but research efforts suffer from disproportionately low representation of the youth who are most at risk. Youth-focused research is critical and should include behavioral, community, and biomedical interventions to create a comprehensive HIV prevention package. The many ethical, legal, and regulatory considerations in conducting HIV research among, and in providing care services to, youth must be addressed so that those at high risk and most likely to benefit can have unfettered access to safe and effective health-promoting interventions. YMSM and minority youth are at substantial HIV risk and urgently need effective HIV prevention tools for which the short and long-term benefits and risks have been carefully considered.

Objectives: The authors sought to evaluate the cost-effectiveness of statins for primary prevention of myocardial infarction (MI) and stroke in patients with chronic kidney disease (CKD)., Background: Patients with CKD have an elevated risk of MI and stroke. Although HMG Co-A reductase inhibitors (“statins”) may prevent cardiovascular events in patients with non–dialysis-requiring CKD, adverse drug effects and competing risks could materially influence net effects and clinical decision-making., Methods: We developed a decision-analytic model of CKD and cardiovascular disease (CVD) to determine the cost-effectiveness of low-cost generic statins for primary CVD prevention in men and women with hypertension and mild-to-moderate CKD. Outcomes included MI and stroke rates, discounted quality-adjusted life years (QALYs) and lifetime costs (2010 USD), and incremental cost-effectiveness ratios., Results: For 65-year-old men with moderate hypertension and mild-to-moderate CKD, statins reduced the combined rate of MI and stroke, yielded 0.10 QALYs, and increased costs by $1,800 ($18,000 per QALY gained). For patients with lower baseline cardiovascular risks, health and economic benefits were smaller; for 65-year-old women, statins yielded 0.06 QALYs and increased costs by $1,900 ($33,400 per QALY gained). Results were sensitive to rates of rhabdomyolysis and drug costs. Statins are less cost-effective when obtained at average retail prices, particularly in patients at lower CVD risk., Conclusions: Although statins reduce absolute CVD risk in patients with CKD, the increased risk of rhabdomyolysis, and competing risks associated with progressive CKD, partly offset these gains. Low-cost generic statins appear cost-effective for primary prevention of CVD in patients with mild-to-moderate CKD and hypertension.

Background: Despite international efforts to arrest increasing rates of overweight and obesity, many population strategies have neglected young adults as a target group. Young adults are at high risk for unhealthy weight gain which tends to persist throughout adulthood with associated chronic disease health risks., Methods/design: TXT2BFiT is a nine month two-arm parallel-group randomized controlled trial aimed at improving weight management and weight-related dietary and physical activity behaviors among young adults. Participants are recruited via general practice (primary medical care) clinics in Sydney, New South Wales, Australia. All participants receive a mailed resource outlining national physical activity and dietary guidelines and access to the study website. Additional resources accessible to the intervention arm via the study website include Smartphone mobile applications, printable handouts, an interactive healthy weight tracker chart, and a community blog. The study consists of two phases: (1) Intensive phase (weeks 1 to 12): the control arm receives four short message service (SMS) text messages; the intervention arm receives eight SMS messages/week tailored to their baseline stage-of-change, one Email/week, and personalized coaching calls during weeks 0, 2, 5, 8, and 11; and (2) Maintenance phase (weeks 14 to 36): the intervention arm receives one SMS message/month, one Email/month and booster coaching calls during months 5 and 8. A sample of N = 354 (177 per arm) is required to detect differences in primary outcomes: body weight (kg) and body mass index (kg/m2), and secondary outcomes: physical activity, sitting time, intake of specific foods, beverages and nutrients, stage-of-change, self-efficacy and participant well-being, at three and nine months. Program reach, costs, implementation and participant engagement will also be assessed., Discussion: This mobile phone based program addresses an important gap in obesity prevention efforts to date. The method of intervention delivery is via platforms that are highly accessible and appropriate for this population group. If effective, further translational research will be required to assess how this program might operate in the broader community., Trial Registration: Australian New Zealand Clinical Trials Registry ACTRN12612000924853.

Objective: To investigate the incentive for primary and secondary prevention associated with experience rating in a retrospective workers' compensation program., Methods: Panel data on 21,558 firms from 1998 to 2007 were used to estimate the relationship between the degree of experience rating and seven measures of workplace occupational health and safety outcomes. We focused on the impact of a policy change in 2004 in which the degree of experience rating was substantially increased for all firms., Results: The 2004 increase in experience rating was associated with a reduction in the total, lost-time, no-lost-time, benefit days, permanent impairment, musculoskeletal disorder, and acute trauma claim rates. These observed changes follow secular trends., Conclusion: The association of experience rating with some claim outcomes and not others in some time periods suggests that firms may focus on claims and cost management practices.

Sudden cardiac death (SCD) is a major cause of mortality in elderly individuals owing to a high prevalence of coronary heart disease, systolic dysfunction, and congestive heart failure (CHF). Although the incidence of SCD increases with age, the proportion of cardiac deaths that are sudden decreases owing to high numbers of other cardiac causes of death in elderly individuals. Implantable cardioverter-defibrillator (ICD) therapy has been demonstrated to improve survival and prevent SCD in selected patients with systolic dysfunction and CHF. However, ICD therapy in elderly patients might not be effective because of a greater rate of pulseless electrical activity underlying SCD and other competing nonarrhythmic causes of death in this population. Although under-represented in randomized trials of ICD use, elderly patients comprise a substantial proportion of the population that qualifies for and receives an ICD for primary prevention under current guidelines. Cardiac resynchronization therapy (CRT), which has been demonstrated to reduce mortality in selected populations with heart failure, is also more commonly used in this group of patients than in younger individuals. In this Review, we examine the causes of SCD in elderly individuals, and discuss the existing evidence for effectiveness of ICD therapy and CRT in this growing population.

Objective: To estimate the cost-effectiveness of enhancing adherence to blood pressure (BP)-lowering drug therapy in a large population without signs of preexisting cardiovascular (CV) disease., Methods: A cohort of 209,650 patients aged 40 to 79 years resident in the Italian Region of Lombardia and newly treated with BP-lowering drugs during 2000 to 2001 was followed from index prescription to 2007. During the follow-up, the 10,688 patients who experienced a hospitalization for a coronary or cerebrovascular event were identified (outcome). Adherence was measured by the proportion of days covered by the therapy with BP-lowering drugs. The cost-effectiveness of enhancing adherence was measured through the incremental cost-effectiveness ratio., Results: Enhancing adherence from 52% (baseline) to 60% and 80% led to a reduced rate for CV outcomes (from 85 to 83 and 77 events every 10,000 person-year, respectively) and increased the cost for drug therapy (from €1,325k to €1,507k and €1,934k every 10,000 person-year, respectively). The resulting incremental cost-effectiveness ratio decreased from €76k (95% confidence interval €74k-€77k) to €74k (95% confidence interval €72k-€75k) for each CV event avoided by enhancing adherence from baseline to 60% and 80%, respectively., Conclusions: Enhancing adherence to BP-lowering medications in the setting of primary CV prevention might offer important benefits in reducing the risk of CV outcome, but at a substantial cost., (Copyright © 2013 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

Aims: To describe aspirin use in primary and secondary prevention and to determine the incremental costs-effectiveness ratio (ICER) per life year gain (LYG) of aspirin use among subjects with, or at high risk of atherothrombotic disease., Design and Subjects: To project the cost-effectiveness of aspirin over 5 years of follow-up, a Markov state transition model was developed with yearly cycles and the following health states: "Alive" (post-CAD) and "Dead." The model compared current coverage observed among 2361 subjects using the prospective Australian subset of Reduction of Atherothrombosis for continued Health (REACH) registry, and hypothetical situation whereby all subjects assumed to be treated. Costs were calculated based on the Australian government reimbursed data for 2010., Main Outcome Measures: ICER per LYG for increased use of aspirin., Results: The use of aspirin in current group varied from 67% to 70%. The base-case analysis showed that increasing aspirin use among subjects with existing CAD in outpatient settings was cost saving, while increasing use of aspirin in primary prevention equated to an ICER of AUD 7126 per LYG., Conclusion: Among subjects with existing CAD aspirin use was shown to be a dominant choice of treatment. However, among patients without existing cardiovascular disease (primary prevention), increased uptake of aspirin was cost effective but with uncertain benefit, with two hemorrhagic bleeding events occurring for every life saved., (© 2011 Blackwell Publishing Ltd.)

Background: Well designed cardiovascular disease (CVD) prevention programmes appear to be generally applicable and effective in reducing exposure to risk factors and the incidence of disease. However, introducing them broadly into clinical practice would have a significant impact on the healthcare budget, and requires careful consideration., Aim: The purpose of this health economic analysis was to assess the potential cost-effectiveness of the model nurse-led, comprehensive CVD primary prevention programme which was prepared and introduced in the EUROACTION project, in high-risk patients in Poland., Methods: A Markov model was developed to assess the long-term costs of preventive intervention. The health states modelled were: event-free (all patients at the beginning of observation), stable angina first year, acute myocardial infarction, stable angina subsequent year, myocardial infarction subsequent year, CVD death, and other causes of death. Health benefits from the reduction in risk factors were estimated based on Framingham risk function assuming the probability of defined health states according to British registers. The time horizon of the analysis was ten years, and one Markov cycle length was one year. The analysis was prepared from the healthcare payer's perspective. A willingness to pay threshold of three gross domestic product (GDP) per capita / quality-adjusted life years (QALY) was used. Univariate sensitivity analysis was conducted. Results were presented as an incremental cost-effectiveness ratio (ICER) expressed as an incremental cost per QALY., Results: In Poland, EUROACTION intervention resulted mainly in reductions in the prevalence of smoking (by 14%) and high blood pressure (by 7%). Intervention on other risk factors, including blood lipids, was found to be less effective. Estimated ICERs were 19,524 PLN for men and 82,262 PLN for women. The programme was even more cost-effective in smokers i.e. estimated ICERs were 12,377 PLN in men and 53,471 PLN in women. The results were most sensitive to variations in health states utilities and cost value range as well as the duration of treatment effect., Conclusions: The model nurse-led, comprehensive CVD primary prevention programme developed in the EUROACTION project appears to be potentially highly cost-effective for high-risk male patients in Poland (below 1 GDP per capita per QALY). For women, the cost-effectiveness was less but still below the acceptable threshold (below three GDP per capita per QALY), although the sensitivity analysis showed that results were a subject of some uncertainty.
