From 2003 to 2014 the proportion of specialty prescription drugs (defined as those reimbursed at $600 or more per thirty-day fill) nearly quadrupled. Over this time period, fills for specialty drugs increased by 198 percent and spending for the drugs increased by 292 percent, as percentages of total drug fills and spending. Median out-of-pocket spending increased by 46 percent for specialty drugs and decreased by 57 percent for nonspecialty drugs during this time., (Project HOPE—The People-to-People Health Foundation, Inc.)

This paper examines the impact of coinsurance exemption for prescription medicines applied to elderly individuals in Spain after retirement. We use a rich administrative dataset that links pharmaceutical consumption and hospital discharge records for the full population aged 58 to 65 years in January 2004 covered by the public insurer in a Spanish region, and we follow them until December 2006. We use a difference-in-differences strategy and exploit the eligibility age for Social Security to control for the endogeneity of the retirement decision. Our results show that this uniform exemption increases the consumption of prescription medicines on average by 17.5%, total pharmaceutical expenditure by 25% and the costs borne by the insurer by 60.4%, without evidence of any offset effect in the form of lower short term probability of hospitalization. The impact is concentrated among consumers of medicines for acute and other non-chronic diseases whose previous coinsurance rate was 30% to 40%.

Background: Medication care is a complicated process in nursing homes. The aim of the study was to offer an overview of inappropriate medication prescription and administration practices in nursing homes in Alsace in order to propose improvement actions to remedy the weaknesses identified., Methods: This study was conducted prospectively in 10 nursing homes under contract with community pharmacies in Alsace. The practices of prescription were examined to determine the prevalence of potentially inappropriate medications, inappropriate and contraindicated medication associations. Crushing and opening practices were also assessed, daily treatment costs were calculated., Results: Two hundred and eighty-four residents were included (age: 87.1 ± 5.6 years). The average number of drugs per resident was 8.1 ± 4.0 (daily treatment cost: 4.19 ± 5.21 €). On average, 1.5 drugs ± 1.4 per prescription were considered as potentially inappropriate (daily treatment cost: 0.49 ± 0.76 €). The contraindication associations concerned 8 % of prescriptions and involved potentially inappropriate drugs in 60 % of cases. Inappropriate associations mainly concerned nervous system drugs. Thirty-three residents were taking more than 2 psychotropic drugs; 23 had more than one benzodiazepine. Regarding drug administration, practices differed from one nursing home to another. Crushing was performed in 8 nursing homes. It concerned 20 residents (7 %) and 69 drugs. In 50 %, the crushing decision was made by nurses without physician or pharmacist supervision. Fifty-seven percent of crushed drugs had a formulation which did not allow crushing (n=39 drugs). The analysis of those items led to the proposal of improvement actions., Conclusion: This study pointed out inappropriate medication practices. Tracking tools for inappropriate clinical practices could be operated by physicians, pharmacists and nursing teams through coordinated multidisciplinary approaches., (Copyright © 2016 Elsevier Masson SAS.

Background: Stevens-Johnson syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are life-threatening dermatologic conditions. Although, the incidence of SJS/TEN in Thailand is high, information on cost of care for SJS/TEN is limited. This study aims to estimate healthcare resource utilization and cost of SJS/TEN in Thailand, using hospital perspective., Methods: A retrospective study using an electronic health database from a university-affiliated hospital in Thailand was undertaken. Patients admitted with SJS/TEN from 2002 to 2007 were included. Direct medical cost was estimated by the cost-to-charge ratio. Cost was converted to 2013 value by consumer price index, and converted to $US using 31 Baht/ 1 $US. The healthcare resource utilization was also estimated., Results: A total of 157 patients were included with average age of 45.3±23.0 years. About 146 patients (93.0%) were diagnosed as SJS and the remaining (7.0%) were diagnosed as TEN. Most of the patients (83.4%) were treated with systemic corticosteroids. Overall, mortality rate was 8.3%, while the average length of stay (LOS) was 10.1±13.2 days. The average cost of managing SJS/TEN for all patients was $1,064±$2,558. The average cost for SJS patients was $1,019±$2,601 while that for TEN patients was $1,660±$1,887., Conclusions: Healthcare resource utilization and cost of care for SJS/TEN in Thailand were tremendous. The findings are important for policy makers to allocate healthcare resources and develop strategies to prevent SJS/TEN which could decrease length of stay and cost of care.

Objective: To examine self-reported financial strain in relation to pharmacy utilization adherence data., Data Sources/study Setting: Survey, administrative, and electronic medical data from Kaiser Permanente Northern California., Study Design: Retrospective cohort design (2006, n = 7,773)., Data Collection/extraction Methods: We compared survey self-reports of general and medication-specific financial strain to three adherence outcomes from pharmacy records, specifying adjusted generalized linear regression models., Principal Findings: Eight percent and 9 percent reported general and medication-specific financial strain. In adjusted models, general strain was significantly associated with primary nonadherence (RR = 1.37; 95 percent CI: 1.04-1.81) and refilling late (RR = 1.34; 95 percent CI: 1.07-1.66); and medication-specific strain was associated with primary nonadherence (RR = 1.42, 95 percent CI: 1.09-1.84)., Conclusions: Simple, minimally intrusive questions could be used to identify patients at risk of poor adherence due to financial barriers., (© Health Research and Educational Trust.)

Objectives: Specialty drugs often represent major medical advances for patients with few other effective options available, but high costs have attracted the attention of both payers and policy makers. We reviewed the evidence regarding the impact of cost sharing on utilization of specialty drugs indicated for rheumatoid arthritis (RA), multiple sclerosis (MS), and cancer, and on the use of nondrug medical services, health outcomes, and spending., Study Design: Systematic review of Medline-indexed studies identified via an OVID search for articles published in English from 1995 to 2014, using combinations of terms for cost sharing and specialty drugs, and/or our 3 conditions of interest. We identified additional studies from reference lists., Results: We identified 19 articles focusing on specialty drugs indicated for MS (n = 9), cancer (n = 8), and RA (n = 8). Studies examined prescription abandonment (n = 3), initiation or any utilization (n = 8), adherence (n = 9), persistence/discontinuation (n = 7), number of claims (n = 1), and drug spending (n = 1). Findings varied by disease, but generally indicated stronger effects for noninitiation or abandonment of a prescription at the pharmacy and somewhat smaller effects for refill behavior and drug spending once patients initiated therapy. Studies have not examined specialty tier cost sharing seen under Medicare Part D or health insurance exchanges, nor effects on medical utilization, spending, or health outcomes., Conclusions: Evidence to date generally indicates reductions in specialty drug utilization associated with higher cost sharing; effects have varied by type of disease and specialty drug use outcome. We draw upon our findings and the gaps in evidence to summarize future directions for research and policy.

Purpose: Evidence of whether the recent economic crisis has or has not had an effect on psychotropic drug consumption is very scarce. Our objective was to determine if there had in fact been an increase in psychotropic drug use as a result of the financial crisis., Methods: In our study a retrospective cohort (between January 1, 2005, and December 31, 2012) was made up of individuals from the general population in a region in the northeast of Catalonia, Spain. We specified a generalized linear mixed model along with combined 'selection on observables' as (propensity scoring) matching and 'selection on unobservables' as (random coefficient) the panel data model methods, and performed inferences using a Bayesian framework., Results: In the period following the economic crisis (post 2009), there was an increase in the consumption of psychotropic drugs which was significantly higher among those who had already been consuming psychotropic drugs prior to 2009 and those most likely to be unemployed. The increase was of greater significance when consumption was measured by the number of drugs being taken, rather than by the defined daily dose (DDD), with the greatest increase occurring in 2011; the very year in which Spain was most affected by the crisis., Conclusions: Once the financial crisis had ended, there was an increase in the severity, rather than the intensity, of mental health disorders in individuals who had already had disorders before the crisis. This increase occurred in those most likely to be unemployed, and the severity was accentuated in the toughest year of the economic crisis.

The purpose of this study was to evaluate the impact of the FilmArray Blood Culture Identification (BCID) Panel on the management of patients with blood cultures growing gram positive cocci and Candida. We retrospectively compared clinical and economic outcomes between patients during the BCID testing period and a matched historical control group before BCID testing was introduced. A total of 84 BCID patients were matched to 252 historical controls. BCID identification of coagulase negative staphylococci contaminants resulted in shorter post-culture length of stay (P < 0.008) and saved roughly $30,000 per 100 patients tested. The BCID led to shorter duration of empirical vancomycin for patients with contaminated blood cultures (P = 0.005) and methicillin-susceptible Staphylococcus aureus bacteremia (P < 0.001). Patients with vancomycin-resistant enterococcal bacteremia received active therapy earlier than historical controls (P = 0.047). The BCID, coupled with antimicrobial stewardship intervention, was a cost effective tool to improve patient care., (Published by Elsevier Inc.)

Background: Increasing immunosuppressant utilization and expenditure is a worldwide challenge as more people successfully live with transplanted organs. Our aims were to characterize utilization of mycophenolate, tacrolimus, cyclosporin, sirolimus, and everolimus in Australian transplant recipients from 2007 to 2013; to identify specific patterns of usage; and to compare Australian utilization with Norwegian, Danish, Swedish, and the Netherlands use., Material and Methods: Australian utilization and expenditure data were captured through national Pharmaceutical Benefits Scheme and Highly Specialized Drug administrative databases. Norwegian, Danish, Swedish, and the Netherlands utilization were retrieved from their healthcare databases. Utilization was compared as defined daily dose per 1000 population per day (DDD/1000 population/day). Data on kidney transplant recipients, the predominant patient group prescribed these medicines, were obtained from international transplant registries., Results: From 2007-2013 Australian utilization of mycophenolic acid, tacrolimus and everolimus increased 2.7-fold, 2.2-fold, and 2.3-fold, respectively. Use of cyclosporin and sirolimus decreased 20% and 30%, respectively. Australian utilization was significantly lower than European utilization (2013) but was increasing at a faster rate. Total Australian expenditure increased approximately AUD$30 million over the study period to almost AUD$100 million in 2013. Kidney transplantation rates increased across each country over this time, with Australia having the lowest rate., Conclusions: Immunosuppressant usage and subsequent expenditure are rising in Australia and Northern Europe. With increased numbers of people living with transplants, and the observed growth potential predicted from Northern European data, this class of medicines can be expected to continue consuming an increasing share of Australian pharmaceutical expenditure into the future.

Oncology biological products are some of the most expensive drugs on the market and are a growing financial burden on patients and health-care systems. By 2020, numerous major biological cancer drugs will lose their patent protection allowing follow-on competitors, known as biosimilars, to enter the market. Clinical and regulatory considerations for biosimilars have begun to harmonise in Europe and the USA to help to define and streamline the pathway for biosimilar market authorisation. Yet, substantial international variation still exists in the pricing and market uptake of approved biosimilar oncology drugs. Differences in national postmarket policies for biosimilars might explain these disparities in pricing and uptake. In this Policy Review, policy approaches to competition between biosimilars and originators used by seven European countries--Belgium, France, Germany, Italy, the Netherlands, Norway, and the UK--and the USA are discussed, chosen because these countries represent a variety of postmarket policies and build on conclusions from previous work. We discuss these policies within the context of interchangeability, physician prescribing, substitutability, pharmacist dispensing, hospital financing and tendering, and pricing., (Copyright © 2016 Elsevier Ltd.

Medicaid enrollees are about twice as likely as the general US population to smoke tobacco: 32 percent of people in the program identify themselves as smokers. This article provides the first data about the effectiveness of state Medicaid programs in promoting smoking cessation. Our analysis of Medicaid enrollees' use of cessation medications found that about 10 percent of current smokers received cessation medications in 2013. Every state Medicaid program covers cessation benefits, but the use of these medications varies widely, with the rate in Minnesota being thirty times higher than that in Texas. Most states could increase their efforts to help smokers quit, working with public health agencies, managed care plans, and others. In 2013 Medicaid spent $103 million on cessation medications-less than 0.25 percent of the estimated cost to Medicaid of smoking-related diseases. Additionally, states that have not expanded Medicaid eligibility in the wake of the Affordable Care Act have higher smoking prevalence and lower utilization rates of cessation medication, compared to expansion states. Given these factors, nonexpansion states will have a greater public health burden related to smoking. Medicaid and public health agencies should work together to make smoking cessation a priority for Medicaid beneficiaries., (Project HOPE—The People-to-People Health Foundation, Inc.)

The relationship between the number of withdrawn/restricted drugs and socioeconomic, health, and welfare indicators were investigated in a comprehensive review of drug regulation information in the United Nations (UN) countries. A total of of 362 drugs were withdrawn and 248 were restricted during 1950-2010, corresponding to rates of 12.02 ± 13.07 and 5.77 ± 8.69 (mean ± SD), respectively, among 94 UN countries. A socioeconomic, health, and welfare analysis was performed for 33 OECD countries for which data were available regarding withdrawn/restricted drugs. The gross domestic product (GDP) per capita, GDP per hour worked, health expenditure per GDP, and elderly population rate were positively correlated with the numbers of withdrawn and restricted drugs (P < 0.05), while the out-of-pocket health expenditure payment rate was negatively correlated. The number of restricted drugs was also correlated with the rate of drug-related deaths (P < 0.05). The World Bank data cross-validated the findings of 33 OECD countries. The lists of withdrawn/restricted drugs showed markedly poor international agreement between them (Fleiss's kappa = -0.114). Twenty-seven drugs that had been withdrawn internationally by manufacturers are still available in some countries. The wide variation in the numbers of drug withdrawals and restrictions among countries indicates the need to improve drug surveillance systems and regulatory communication networks.

Study Objectives: The clinical efficacy and cost-effectiveness of influenza antiviral use are controversial, with recent analyses suggesting potentially limited value. Thus, the objectives of this study were to describe influenza antiviral expenditures overall and by health care setting over a 10-year period (2003-2012) and to assess the correlation between outpatient influenza antiviral prescription use and influenza-like illness (ILI) outpatient visits., Design: Retrospective, cross-sectional study., Data Sources: IMS Health National Sales Perspectives and Xponent databases and Centers for Disease Control and Prevention ILINet national influenza surveillance system database., Patients: All prescriptions for oseltamivir, rimantadine, or zanamivir from community pharmacies, mail order pharmacies, clinics, nonfederal hospitals, and other health care settings (federal hospitals, military facilities, jails and prisons, universities, staff-model health maintenance organizations, veterinary hospitals and clinics, and long-term care facilities) between January 1, 2003, and December 31, 2012., Measurements and Main Results: Prescribing rates were calculated (prescriptions/1000 persons) for each year from 2003 to 2012 by using U.S. Census Bureau data. Influenza season was defined as July 1-June 30 of each calendar year. Linear regression assessed the correlation between influenza antiviral expenditures, prescription use, and ILI diagnoses. From 2003 to 2012, influenza antiviral drug expenditures accounted for $3.74 billion, with the majority from community pharmacies. After adjusting for inflation, no growth was observed for expenditures. A total of 32.8 million influenza antiviral prescriptions were dispensed from community pharmacies during the study period, and these prescriptions experienced 133.2% growth from 2003 to 2012. One third of expenditures and one quarter of dispensed prescriptions were in 2009. Influenza seasons were correlated with ILI and antiviral prescriptions. Annual community pharmacy expenditures were also associated with influenza antiviral prescriptions dispensed over the 10-year period., Conclusion: Influenza antivirals totaled $3.74 billion in the United States from 2003 to 2012, with the majority in 2009 and from community pharmacies. Influenza antivirals constituted a small proportion of total medication expenditures, but unforeseen pandemics resulted in unusually high use and expenditures. Influenza antiviral prescriptions dispensed from community pharmacies were associated with ILI and drug expenditures., (© 2015 Pharmacotherapy Publications, Inc.)

Sepsis and severe sepsis in particular remain a major health problem worldwide. Their cost to society extends well beyond lives lost, as the impact of survivorship is increasingly felt. A review of the medical literature was completed in MEDLINE using the search phrases "severe sepsis" and "septic shock" and the MeSH terms "epidemiology", "statistics", "mortality", "economics", and "quality of life". Results were limited to human trials that were published in English from 2002 to 2014. Articles were classified by dominant themes to address epidemiology and outcomes, including quality of life of both patient and family caregivers, as well as societal costs. The severity of sepsis is determined by the number of organ failures and the presence of shock. In most developed countries, severe sepsis and septic shock account for disproportionate mortality and resource utilization. Although mortality rates have decreased, overall mortality continues to increase and is projected to accelerate as people live longer with more chronic illness. Among those who do survive, impaired quality of life, increased dependence, and rehospitalization increase healthcare consumption and, along with increased mortality, all contribute to the humanistic burden of severe sepsis. A large part of the economic burden of severe sepsis occurs after discharge. Initial inpatient costs represent only 30 % of the total cost and are related to severity and length of stay, whereas lost productivity and other indirect medical costs following hospitalization account for the majority of the economic burden of sepsis. Timeliness of treatment as well as avoidance of intensive care unit (ICU)-acquired illness/morbidity lead to important differences in both cost and outcome of treatment for severe sepsis and represent areas where improvement in care is possible. The degree of sophistication of a health system from a national perspective results in significant differences in resource use and outcomes for patients with serious infections. Comprehensive understanding of the cost and humanistic burden of severe sepsis provides an initial practical framework for health policy development and resource use.

We used data on more than 1.5 million Medicaid enrollees to examine the impact of changes in prescription drug use on medical costs. For three distinct groups of enrollees, we estimated the effects of aggregate prescription drug use-and, more specifically, the use of medications to treat eight chronic noncommunicable diseases-on total nondrug, inpatient, outpatient, and other Medicaid spending. We found that a 1 percent increase in overall prescription drug use was associated with decreases in total nondrug Medicaid costs by 0.108 percent for blind or disabled adults, 0.167 percent for other adults, and 0.041 percent for children. Reductions in combined inpatient and outpatient spending from increased drug utilization in Medicaid were similar to an estimate for Medicare by the Congressional Budget Office. Moving forward, policy makers evaluating proposed changes that alter medication use among the nearly seventy million Medicaid recipients should consider the net effects on program spending to ensure that scarce federal and state health care dollars are allocated efficiently., (Project HOPE—The People-to-People Health Foundation, Inc.)

Objective: At our institution, our microbiologist, pharmacist, and infectious disease (ID) team meet to discuss ID patients, and this meeting is referred to as microbiology rounds. We hypothesized that our microbiology rounds reduce antibiotic costs. The study involved a review of 80 patients with an ID consultation order at each of the 3 hospitals: hospital A (HA) (only HA has microbiology rounds), hospital B (HB), and hospital C (HC). Of this population, we included patients with a positive blood culture. Thirty-six patients who met the above criteria were included in the study. The average antibiotic cost/patient/day at HA, HB, and HC were $66.0, $123, and $109, respectively. Also, we found that change in antibiotics was appropriate when compared to the final microbiology results in 90%, 44%, and 40% of the time at HA, HB, and HC, respectively. Herein, we found an association between conducting microbiology rounds and reduction of antibiotic cost., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Importance: Understanding factors that lead to nonadherence to glaucoma treatment is important to diminish glaucoma-related disability., Objectives: To determine whether the implementation of the Medicare Part D prescription drug benefit affected rates of cost-related nonadherence and cost-reduction strategies in Medicare beneficiaries with and without glaucoma and to evaluate associated risk factors for such nonadherence., Design, Setting, and Participants: Serial cross-sectional study using 2004 to 2009 Medicare Current Beneficiary Survey data linked with Medicare claims. Coding to extract data started in January 2014 and analyses were performed between September and November of 2014. Participants were all Medicare beneficiaries, including those with a glaucoma-related diagnosis in the year prior to the collection of the survey data, those with a nonglaucomatous ophthalmic diagnosis in the year prior to the collection of the survey data, and those without a recent eye care professional claim., Intervention: Effect of the implementation of the Medicare Part D drug benefit., Main Outcomes and Measures: The change in cost-related nonadherence and the change in cost-reduction strategies., Results: Between 2004 and 2009, the number of Medicare beneficiaries with glaucoma who reported taking smaller doses and skipping doses owing to cost dropped from 9.4% and 8.2% to 2.7% (P < .001) and 2.8%, respectively (P = .001). However, reports of failure to obtain prescriptions owing to cost did not improve in the same period (3.4% in 2004 and 2.1% in 2009; P = .12). After Part D, patients with glaucoma had a decrease in several cost-reduction strategies, namely price shopping (26.2%-15.2%; P < .001), purchasing outside the United States (6.9%-1.3%; P < .001), and spending less money to save for medications (8.0% to 3.5%; P < .001). Using a multivariate analysis, the main independent risk factors common to all cost-related nonadherence measures were female sex, younger age, lower income (<$30 000), self-reported visual disability, and a smaller Lawton index., Conclusions and Relevance: After the implementation of Part D, there was a decrease in the rate that beneficiaries with glaucoma reported engaging in cost-saving measures. Although there was a decline in the rate of several cost-related nonadherence behaviors, patients reporting failure to fill prescriptions owing to cost remained stable. This suggests that efforts to improve cost-related nonadherence should focus both on financial hardship and medical therapy prioritization, particularly in certain high-risk sociodemographic groups.

Introduction: Analysing drug consumption in large population groups lets us observe consumption trends and compare them between different settings., Objective: to analyse the time trends for consumption and costs of specific drugs used to treat dementia in the region of Madrid (Spain) and compare trends by sex and age cohort., Methods: Descriptive study of cholinesterase inhibitors (N06DA) and memantine (N06DX01) dispensed in Madrid between 2002 and 2012 and covered by the Spain's national health system. Consumption was calculated by analysing changes in DDD (defined daily doses) to find total and yearly increases. The cost was estimated based on DDD price. To compare consumption rates by age and sex, we calculated DDD per 100 inhabitants/day., Results: Between 2002 and 2012, consumption of drugs used to treat dementia increased sixfold. During this period, cholinesterase inhibitors accounted for 76.70% of the drugs consumed and memantine, 23.30%. The estimated cost rose by a by a factor of 5.7 over 11 years (or by a factor of 4 taking into account the use of generic drugs). In 2012, 2.42% of the patients aged 65 or over consumed cholinesterase inhibitors (women 2.82%, men 1.83%) and 0.90% consumed memantine (women 1.10%, men 0.61%). Consumption increased in age cohorts up to 86 to 90 (5.84% for cholinesterase inhibitors and 2.33% for memantine) and declined thereafter., Conclusions: Consumption of cholinesterase inhibitors and memantine gradually increased, but consumption in 2012 did not reach levels equivalent to dementia prevalence figures. Pharmaceutical expenditure restraint measures may temporarily slow the cost increase temporarily but if the same trend of consumption persists, costs will rise., (Copyright © 2013 Sociedad Española de Neurología.

Pharmaceutical expenditure has increased rapidly across many Organisation for Economic Cooperation and Development (OECD) countries over the past three decades. This growth is an increasing concern for governments and other third-party payers seeking to provide equitable and comprehensive healthcare within sustainable budgets. In order to create headroom for increasing utilisation, and to fund new high-cost therapies, there is an active push to 'disinvest' from low-value drugs. The aim of this article is to review how reimbursement policy decision makers have sought to partially or completely disinvest from drugs in a range of OECD countries (UK, France, Canada, Australia and New Zealand) where they are publicly funded or subsidised. We employed a systematic literature search strategy and the incorporation of grey literature known to the authorship team. We canvass key policy instruments from each country to outline key approaches to the identification of candidate drugs for disinvestment assessment (passive approaches vs. more active approaches); methods of disinvestment and value-based purchasing (de-listing, restricting treatment, price or reimbursement rate reductions, encouraging generic prescribing); lessons learnt from the various approaches; the potential role of coverage with evidence development; and the need for careful stakeholder management. Dedicated sections are provided with detailed coverage of policy approaches (with drug examples) from each country. Historically, countries have relied on 'passive disinvestment'; however, due to (1) the availability of new cost-effectiveness evidence, or (2) 'leakage' in drug utilisation, or (3) market failure in terms of price competition, there is an increasing focus towards 'active disinvestment'. Isolating low-value drugs that would create headroom for innovative new products to enter the market is also motivating disinvestment efforts by multiple parties, including industry. Historically, disinvestment has mainly taken the form of price reductions, especially when market failures are perceived to exist, and restricting treatment to subpopulations, particularly when a drug is no longer considered value for money. There is considerable experimentation internationally in mechanisms for disinvestment and the opportunity for countries to learn from each other. Ongoing evaluation of disinvestment strategies is essential, and ought to be reported in the peer-reviewed literature.

Background: The proportion of total healthcare expenditures spent on drugs has continued to grow in countries of all income categories. Policy-makers are under pressure to control pharmaceutical expenditures without adversely affecting quality of care. Financial incentives seeking to influence prescribers' behaviour include budgetary arrangements at primary care and hospital settings (pharmaceutical budget caps or targets), financial rewards for target behaviours or outcomes (pay for performance interventions) and reduced benefit margin for prescribers based on medicine sales and prescriptions (pharmaceutical reimbursement rate reduction policies). This is the first update of the original version of this review., Objectives: To determine the effects of pharmaceutical policies using financial incentives to influence prescribers' practices on drug use, healthcare utilisation, health outcomes and costs (expenditures)., Search Methods: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (searched 29/01/2015); MEDLINE, Ovid SP (searched 29/01/2015); EMBASE, Ovid SP (searched 29/01/2015); International Network for Rational Use of Drugs (INRUD) Bibliography (searched 29/01/2015); National Health Service (NHS) Economic Evaluation Database (searched 29/01/2015); EconLit - ProQuest (searched 02/02/2015); and Science Citation Index and Social Sciences Citation Index, Institute for Scientific Information (ISI) Web of Knowledge (citation search for included studies searched 10/02/2015). We screened the reference lists of relevant reports and contacted study authors and organisations to identify additional studies., Selection Criteria: We included policies that intend to affect prescribing by means of financial incentives for prescribers. Included in this category are pharmaceutical budget caps or targets, pay for performance and drug reimbursement rate reductions and other financial policies, if they were specifically targeted at prescribing or drug utilisation. Policies in this review were defined as laws, rules, regulations and financial and administrative orders made or implemented by payers such as national or local governments, non-government organisations, private or social insurers and insurance-like organisations. One of the following outcomes had to be reported: drug use, healthcare utilisation, health outcomes or costs. The study had to be a randomised or non-randomised trial, an interrupted time series (ITS) analysis, a repeated measures study or a controlled before-after (CBA) study., Data Collection and Analysis: At least two review authors independently assessed eligibility for inclusion of studies and risks of bias using Cochrane Effective Practice and Organisation of Care (EPOC) criteria and extracted data from the included studies. For CBA studies, we reported relative effects (e.g. adjusted relative change). The review team re-analysed all ITS results. When possible, the review team also re-analysed CBA data as ITS data., Main Results: Eighteen evaluations (six new studies) of pharmaceutical policies from six high-income countries met our inclusion criteria. Fourteen studies evaluated pharmaceutical budget policies in the UK (nine studies), two in Germany and Ireland and one each in Sweden and Taiwan. Three studies assessed pay for performance policies in the UK (two) and the Netherlands (one). One study from Taiwan assessed a reimbursement rate reduction policy. ITS analyses had some limitations. All CBA studies had serious limitations. No study from low-income or middle-income countries met the inclusion criteria.Pharmaceutical budgets may lead to a modest reduction in drug use (median relative change -2.8%; low-certainty evidence). We are uncertain of the effects of the policy on drug costs or healthcare utilisation, as the certainty of such evidence has been assessed as very low. Effects of this policy on health outcomes were not reported. Effects of pay for performance policies on drug use and health outcomes are uncertain, as the certainty of such evidence has been assessed as very low. Effects of this policy on drug costs and healthcare utilisation have not been measured. Effects of the reimbursement rate reduction policy on drug use and drug costs are uncertain, as the certainty of such evidence has been assessed as very low. No included study assessed the effects of this policy on healthcare utilisation or health outcomes. Administration costs of the policies were not reported in any of the included studies., Authors' Conclusions: Although financial incentives are considered an important element in strategies to change prescribing patterns, limited evidence of their effects can be found. Effects of policies, including pay for performance policies, in improving quality of care and health outcomes remain uncertain. Because pharmaceutical policies have uncertain effects, and because they might cause harm as well as benefit, proper evaluation of these policies is needed. Future studies should consider the impact of these policies on health outcomes, drug use and overall healthcare expenditures, as well as on drug expenditures.

The cost effectiveness of antimicrobial stewardship (AMS) programmes was reviewed in hospital settings of Organisation for Economic Co-operation and Development (OECD) countries, and limited to adult patient populations. In each of the 36 studies, the type of AMS strategy and the clinical and cost outcomes were evaluated. The main AMS strategy implemented was prospective audit with intervention and feedback (PAIF), followed by the use of rapid technology, including rapid polymerase chain reaction (PCR)-based methods and matrix-assisted laser desorption/ionisation time-of-flight (MALDI-TOF) technology, for the treatment of bloodstream infections. All but one of the 36 studies reported that AMS resulted in a reduction in pharmacy expenditure. Among 27 studies measuring changes to health outcomes, either no change was reported post-AMS, or the additional benefits achieved from these outcomes were not quantified. Only two studies performed a full economic evaluation: one on a PAIF-based AMS intervention; and the other on use of rapid technology for the selection of appropriate treatment for serious Staphylococcus aureus infections. Both studies found the interventions to be cost effective. AMS programmes achieved a reduction in pharmacy expenditure, but there was a lack of consistency in the reported cost outcomes making it difficult to compare between interventions. A failure to capture complete costs in terms of resource use makes it difficult to determine the true cost of these interventions. There is an urgent need for full economic evaluations that compare relative changes both in clinical and cost outcomes to enable identification of the most cost-effective AMS strategies in hospitals., (Copyright © 2015 Elsevier B.V. and the International Society of Chemotherapy.

Purpose: The US Food and Drug Administration (FDA) communicated the potential cardiovascular risk of thiazolidinediones (rosiglitazone and pioglitazone) in 2007 and required a Risk Evaluation and Mitigation Strategy (REMS) for rosiglitazone in 2010. It also communicated in 2010 the potential risk of bladder cancer with pioglitazone use. This study examined the effects of these multiple FDA actions on utilization and reimbursed costs of thiazolidinediones in state Medicaid programs., Methods: State Drug Utilization Data from the Centers for Medicare & Medicaid Services were assessed. An interrupted time series design and segmented linear regression models were used to examine changes in market shares according to both prescription volume and reimbursed costs for rosiglitazone and pioglitazone in the Northeast and Midwest regions of the United States after multiple FDA actions., Findings: Compared with expected rates, there were relative reductions of 65.84% (Northeast region) and 55.09% (Midwest region) in the use of rosiglitazone at 1 year after the 2007 FDA actions for thiazolidinediones and cardiac risk. At the same time, relative increases of 7.30% and 9.28% in the use of pioglitazone were observed in the Northeast and Midwest regions, respectively. Changes in both use and costs of rosiglitazone after the 2010 REMS program could not be estimated because of the already low rates (~1%) before REMS was implemented. One year after the 2010 FDA actions for pioglitazone and its possible association with bladder cancer, relative reductions in pioglitazone use of 21.41% (Northeast region) and 18.12% (Midwest region) were detected., Implications: The Northeast and Midwest regions reported similar patterns of changes after the FDA actions. Use and costs of rosiglitazone were substantially reduced after the 2007 FDA actions for cardiovascular risk, and this drug was rarely used after the 2010 REMS program. Conversely, use and costs of pioglitazone were substantially reduced after the 2010 FDA actions regarding the drug's possible risk of bladder cancer., Competing Interests: The authors have indicated that they have no conflicts of interest regarding the content of this article., (Copyright © 2015 Elsevier HS Journals, Inc.

Rationale: The United States is one of only two countries that permit direct-to-consumer advertising (DTCA) of prescription drugs, and many questions remain regarding its effects., Objectives: To quantify the association between asthma-related DTCA, pharmacy sales, and healthcare use., Methods: This was an ecological study from 2005 through 2009 using linked data from Nielsen (DTCA television ratings), the IMS Health National Prescription Audit (pharmacy sales), and the MarketScan Commercial Claims data (healthcare use) for 75 designated market areas in the United States. We used multilevel Poisson regression to model the relationship between DTCA and rates of prescriptions and use within and across designated market areas. Main outcome measures include (1) volume of total, new, and refilled prescriptions for advertised products based on pharmacy sales; (2) prescription claims for asthma medications; and asthma-related (3) emergency department use, (4) hospitalizations, and (5) outpatient encounters among the commercially insured., Measurements and Main Results: Four Food and Drug Administration-approved asthma medicines were advertised during the period examined: (1) fluticasone/salmeterol (Advair), (2) mometasone furoate (Asmanex), (3) montelukast (Singulair), and (4) budesonide/formoterol (Symbicort). After adjustment, each additional televised advertisement was associated with 2% (incident rate ratio, 1.02; 95% confidence interval, 1.01-1.03) higher pharmacy sales rate from 2005 through 2009, although this effect varied across the three consistently advertised therapies examined. Among the commercially insured, DTCA was positively and significantly associated with emergency room visits related to asthma (incident rate ratio, 1.02; 95% confidence interval, 1.01-1.04), but there was no relationship with hospitalizations or outpatient encounters., Conclusions: Among this population, DTCA was associated with higher prescription sales and asthma-related emergency department use.

Purpose: Recent guidelines expand indications for statins. However, research on practical economic feasibility and cost-effectiveness in low-risk people is lacking. We aimed to describe the incidence of cardiovascular events (CVE), their total direct costs and the hypothetical effects of wide provision of statins on those rates and expenditures., Methods: We conducted a population-based cohort study using administrative data among low risk individuals. Estimators of effects of statins were taken from Cholesterol Treatment trialist metaanalysis and from Heart Protection Study trial. Two statin prices were used for analyses: National Italian Health System (€ 0.36) and the International Drug Price Indicator (€ 0.021)., Results: Overall, 920,067 persons at low risk were identified and 14,849 CVE were registered (incidence rate 27.3 per 10,000 person-years). Direct costs for hospitalizations for CVE were 143 M €. Universal provision of statins would result in a significant decrease in CVE rates, from 27.3 to 17.5 per 10,000 person-years (PY) (95% confidence interval (CI): 15.8-19.4). Universal prescription of simvastatin 20 mg would cost 802 M €. Otherwise, provision of simvastatin at International Drug Price Indicator's prices would be both clinically effective and cost saving in men older than age 44 (observed expenditures 120 M €, expected 97.4 M €) but not in women (observed expenditures 22.7 M €, expected 36.5 M €)., Conclusions: Among a low-risk population, hypothetical universal provision of low-cost simvastatin to men over 44 years could be both clinically effective and a cost-saving strategy.

Introduction: On July 1, 2011, the Chinese government launched a national Action Plan for antibiotic stewardship targeting antibiotic misuse in public hospitals. The aim of this study was to evaluate the impacts of the Action Plan in terms of frequency and intensity of antibiotic utilization and patients costs in public general hospitals., Methods: Administrative pharmacy data from July 2010 to June 2014 were sampled from 65 public general hospitals and divided into three segments: (1) July 2010 to June 2011 as the preparation period; (2) July 2011 to June 2012 as the intervention period; and (3) July 2012 to June 2014 as the assessment period. The outcome measures included (1) antibiotic prescribing rates; (2) intensity of antibiotic consumption; (3) patients costs; and (4) duration of peri-operative antibiotic treatment in clean surgeries of thyroidectomy, breast, hernia, and orthopedic procedures. Longitudinal and cross-sectional analyses were conducted., Results: Longitudinal analyses showed significant trend changes in the frequency and intensity of antibiotic consumption, the patients' costs on antibiotics, and the duration of antibiotic treatment received by surgical patients undergoing the 4 clean procedures during the intervention period. Cross-sectional analyses showed that the antibiotic prescribing rates were reduced to 35.3% and 12.9% in inpatient and outpatient settings, that the intensity of antibiotic consumption was reduced to 35.9 DDD/100 bed-days, that patients' costs on antibiotics were reduced significantly, and that the duration of peri-operative antibiotic treatment received by surgical patients undergoing the 4 types of clean procedures decreased to less than 24 hour during the assessment period., Conclusion: The Action Plan, as a combination of managerial and professional strategies, was effective in reducing the frequency and intensity of antibiotic consumption, patients' costs on antibiotics, and the duration of peri-operative antibiotic treatment in the 4 clean surgeries.

This paper investigates whether patient-level factors, in particular cost considerations, affect the physicians' prescribing decisions. In the context of a natural experiment, we examine the effect of the first US commercial free-antibiotics program on retail antibiotic sales. We find an overall increase in antibiotic prescriptions under the program and substitutions to covered antibiotics from not-covered antibiotics. The shift away from not-covered antibiotics, particularly from those without covered equivalents, indicates a change in the physicians' prescribing decisions. We locate stronger program effects in low-income areas. Our findings, robust to a variety of specifications, are in contrast with previous literature., (Copyright © 2013 John Wiley & Sons, Ltd.)

Objective: To review international policies to control expenditure on pharmaceuticals by influencing the behaviour of patients and providers and regulating the pharmaceutical industry., Method: Systematic review of experimental and quasi-experimental studies. Published studies were identified with an electronic search strategy using MEDLINE and EMBASE from 1980 to May 2012. Studies were eligible if they assessed the effect of policies aimed at influencing the behaviour of patients and providers, and regulating the pharmaceutical industry. Outcome measures included pharmaceutical expenditure, prices or utilization; other resource use relating to pharmaceuticals; and health outcomes and patients' or providers' behaviour relating to pharmaceutical use. Quality assessment criteria for each study design were developed based on the standard criteria recommended by the Cochrane Effective Practice and Organisation of Care (EPOC) group. The review includes studies based on randomized controlled trials and rigorous quasi-experimental designs (interrupted time-series and controlled before-and-after studies). Studies were excluded if they were conducted within a single hospital or practice; related to pharmaceutical care services or disease management; had less than 6 months of follow-up period (or less than 12 months overall for interrupted time series); if data in controlled before-and-after studies were not collected contemporaneously or if no rationale was stated for the choice of control group; or if relevant and interpretable data were not presented., Results: A total of 255 studies met the inclusion criteria for this review. The majority of the studies relating to patients evaluated cost sharing interventions such as user charges (52 studies). User charges do reduce utilization of pharmaceuticals, and reduce public expenditure by shifting costs to patients. But they reduce the use of essential as well as non-essential drugs, and without adequate exemptions they affect vulnerable groups disproportionately. The majority of studies relating to doctors evaluated the effects of educational approaches (78 studies), reimbursement restrictions (48 studies) and incentive systems (22 studies). Evidence on these policies is of mixed quality. It appears possible to influence prescribing modestly, through various means, but it is essential that messages to prescribers are based on good evidence of effectiveness and cost-effectiveness. Twenty-nine studies related to industry regulation, and they were of mixed quality. Evidence from studies of reference pricing suggests that this may result in cost savings. These are, however, achieved not by companies reducing or restraining prices, or by reductions in the overall volume of prescriptions, but by some shifts in use and shifting costs to patients, with consequent adverse effects on the equity of access to medicines. Other price and profit controls remain almost completely lacking in evaluative evidence., Conclusions: It may be that the undesirable consequences of policies influencing patients, particularly user charges, can outweigh the benefits. To influence demand for pharmaceuticals, it is more appropriate to influence prescribing doctors and although interventions to improve prescribing practice have been developed, they often achieve relatively modest benefits and sometimes at high cost. Good evaluative evidence related to industry regulation is scarce despite its policy importance., (© The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.)

Objective: To assess the effectiveness of managed care plans that limited access to infusion biologics via a step therapy policy., Study Design: This was a retrospective cohort study using Symphony Health Solutions claims databases that included payer, prescription (Rx), diagnosis (Dx) and procedure (Px) information with unique anonymized patient identifiers., Methods: The percentage of patients with claims for infusion and subcutaneous (SQ) biologics were evaluated across three increasingly restrictive cohorts: (1) patients in step therapy plans versus all others in the database (population), (2) patients in step therapy plans versus patients that were members of plans that were roughly matched (matched) and (3) a subsample of patients that were members of step therapy plans that had sufficient data for a pre/post analysis (pre/post)., Results: The population analysis comparison showed 5.1% fewer patients (p < 0.0001) with claims for infusion biologics among step therapy plans than among the overall plans. The more controlled matched and pre/post analyses showed a greater percentage of patients with claims for intravenous products in the plans with step therapy policies versus plans without step therapy policies, differences of +7.0% (p < 0.0001) and +2.8% (p = 0.0522), respectively., Conclusions: Policies designed to limit utilization of infusion biologics showed equivocal results. In the near term, the intended effects of implementing step therapy policies may be limited by relatively small numbers of patients that are affected relative to the total number of users.

Purpose: To enable easier access to triptans, the drug of choice for moderate to severe migraine, some countries have made triptans available without prescription, that is, over the counter (OTC). Concern has been raised about this. The aim of this study was to describe the utilization pattern of triptans in Sweden before and after the OTC switch., Methods: Wholesaler and aggregated sales data from all Swedish pharmacies 1991 to 2011 and patient identity data on dispensed prescriptions 2007 and 2011 from the Swedish National Prescribed Drug Register were used to investigate volume and expenditure of triptans. The databases contain complete data for all drugs sold in Sweden or dispensed to all Swedish inhabitants (9.5 million in 2012)., Results: Volumes of triptans have increased to 7.0 million defined daily doses (DDD) on prescriptions and 0.7 million DDDs OTC in 2011. Prescriptions were dispensed to 10.0 and 10.1 per 1000 inhabitants in 2007 and 2011, respectively. Although half of those dispensed triptans in 2007 were not in 2011, the incidence remained stable at 2.8 patients per thousand person-years. In 2011, the 10% of the heaviest users accounted for 44% and 48% of dispensed triptans in women and men, respectively., Conclusions: Triptans OTC and the volumes dispensed on prescription have increased as has the DDD per patient purchasing triptans on prescription. However, the number of patient's dispensed triptans on prescription has remained stable. A concern is that almost half of prescribed triptans are purchased by 10% of the users., (Copyright © 2014 John Wiley & Sons, Ltd.)

Objectives: To explore criteria regulating treatment with reimbursed biologic disease-modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA) across Europe and to relate criteria to indicators of national socioeconomic welfare., Methods: A cross-sectional study among 46 European countries. One expert from each country completed a questionnaire on criteria regulating the start, maintenance/stop and switch of reimbursed bDMARDs. A composite score was developed to evaluate the level of restrictions in prescription of a first bDMARD (0=highly restricted, 5=most liberal). The level of restrictiveness was correlated with national socioeconomic welfare indicators., Results: In 10 countries (22%), no bDMARD was reimbursed. Among 36 countries with at least one biologic reimbursed, 23(64%) had no requirement for disease duration to initiate a biologic. Half of the countries required a failure of two synthetic DMARDs to qualify for therapy. 31 countries specified a minimum level of disease activity to be fulfilled and in 20 (56%) countries cut-off for disease activity score with 28-joint assessment was higher than 3.2. Four countries (11%) had the maximum composite score (most liberal) and 20 (56%) scored between 0 and 2 (more restrictive). Criteria for initiation of a bDMARD were negatively associated with countries' socioeconomic welfare (-0.34 to -0.64), and a moderate positive correlation was found between the composite score and welfare indicators (0.59-0.72). Only some countries had regulations for stopping (n=14(39%)) or switching (n=19(53%))., Conclusions: Clinical criteria regulating prescription of bDMARDs in RA differ significantly across Europe. Countries with lower socioeconomic welfare tend to have stricter eligibility criteria, pointing to inequities in access to treatment., (Published by the BMJ Publishing Group Limited.

Objective: To assess treatment patterns, health care resource utilization (HRU), and costs among previously stimulant-treated children and adolescents with attention-deficit hyperactivity disorder (ADHD) receiving atypical antipsychotic (AAP) prescriptions in Quebec., Methods: Health care claims data extracted from Quebec's provincial health plan database between March 2007 and February 2012 were analyzed. Children and adolescents (6 to 17 years) with ADHD who were taking a stimulant and either switched to, or augmented with, an AAP (with the first AAP defined as the index AAP) without a documented diagnosis for which AAPs are Health Canada-approved were included. Discontinuation, augmentation, and switching of the index AAP during the 12-month, follow-up period were estimated using Kaplan-Meier survival analysis. HRU and costs for the 6 months before (baseline period) and after initiation of the index AAP were compared., Results: A total of 453 children and adolescents with ADHD, mostly male (74.6%) and aged 6 to 12 years (73.7%), met the inclusion criteria. The 12-month discontinuation, augmentation, and switching rates were 45.5%, 68.2%, and 80.7%, respectively. Patients had, on average, more all-cause prescription fills (22.2, compared with 13.3) and incurred more all-cause pharmacy ($889, compared with $710), total medical ($1096, compared with $644), and total health care ($1985, compared with $1354) costs during the 6-month study period than during the 6-month baseline period (all P < 0.05). Similarly, ADHD-related total health care costs were higher during the study period ($1269, compared with $835; P < 0.05); all-cause and ADHD-related total health care costs increased by 46.6% and 52.0%, respectively., Conclusion: Use of an AAP among stimulant-treated children and adolescents with ADHD in Quebec was associated with high rates of therapy changes and increased HRU and costs.

Background: Information is limited regarding utilization patterns and costs for chronic kidney disease-mineral and bone disorder (CKD-MBD) medications in Medicare Part D-enrolled dialysis patients., Study Design: Retrospective cohort study., Setting & Participants: Annual cohorts of dialysis patients, 2007-2010., Predictors: Cohort year, low-income subsidy status, and dialysis provider., Outcomes: Utilization and costs of prescription phosphate binders, oral and intravenous vitamin D analogues, and cinacalcet., Measurements: Using logistic regression, we calculated adjusted odds of medication use for low-income subsidy versus non-low-income subsidy patients and for patients from various dialysis organizations, and we report per-member-per-month and average out-of-pocket costs., Results: Phosphate binders (∼83%) and intravenous vitamin D (77.5%-79.3%) were the most commonly used CKD-MBD medications in 2007 through 2010. The adjusted odds of prescription phosphate-binder, intravenous vitamin D, and cinacalcet use were significantly higher for low-income subsidy than for non-low-income subsidy patients. Total Part D versus CKD-MBD Part D medication costs increased 22% versus 36% from 2007 to 2010. For Part D-enrolled dialysis patients, CKD-MBD medications represented ∼50% of overall net Part D costs in 2010., Limitations: Inability to describe utilization and costs of calcium carbonate, an over-the-counter agent not covered under Medicare Part D; inability to reliably identify prescriptions filled through a non-Part D reimbursement or payment mechanism; findings may not apply to dialysis patients without Medicare Part D benefits or with Medicare Advantage plans, or to pediatric dialysis patients; could identify only prescription drugs dispensed in the outpatient setting; inability to adjust for MBD laboratory values., Conclusions: Part D net costs for CKD-MBD medications increased at a faster rate than costs for all Part D medications in dialysis patients despite relatively stable use within medication classes. In a bundled environment, there may be incentives to shift to generic phosphate binders and reduce cinacalcet use., (Copyright © 2014 National Kidney Foundation, Inc. All rights reserved.)

Background: The successful diffusion of new drugs is crucial for both pharmaceutical companies and patients-and of wider stakeholder concern, including for the funding of healthcare provision. Micro-level characteristics (the socio-demographic and professional characteristics of medical professionals), meso-level characteristics (the prescribing characteristics of doctors, the marketing efforts of pharmaceutical companies, interpersonal communication among doctors, drug attributes, and the characteristics of patients), and macro-level characteristics (government policies) all influence the diffusion of new drugs. This systematic literature review examines the micro- and meso-level characteristics of early prescribers of newly introduced drugs. Understanding the characteristics of early adopters may help to speed up the diffusion process, promote cost-efficient prescribing habits, forecast utilisation, and develop targeted intervention strategies., Methods: The PubMed and Scopus electronic databases were chosen for their extensive coverage of the pertinent literature and used to identify 205 potentially relevant studies by means of a four-layered search string. The 35 studies deemed eligible were then synthetized carefully and critically, to extract variables relevant to this review., Results: Early adoption of new drugs is not a personal trait, independent of drug type, but early adopters share both micro- and meso-level characteristics. At prescriber level, doctors' interest in particular therapeutic areas, participation in clinical trials, and volume of prescribing-either in total or within the therapeutic class of the new drug-increase the likelihood of early adoption. The marketing efforts of pharmaceutical companies and doctors' professional and social interactions leading to prescribing contagion are very powerful predictors of new drug uptake. At patient level, doctors with younger patients, patients with higher socioeconomic statuses and/or patients with poorer health statuses are more inclined to prescribe new drugs early. In contrast, the socio-demographic characteristics of prescribers and many practice-related factors play little role in the adoption process., Conclusions: The most powerful predictors of new drug uptake include the doctors' strong scientific commitment, high prescribing volume in total or in within the therapeutic class of the new drug, high exposure to marketing, and intense communication with colleagues.

Background: Hepatitis B virus (HBV) infection is a significant clinical and financial burden for chronic hepatitis B (CHB) patients. In Beijing, China, partial reimbursement on antiviral agents was first implemented for the treatment of CHB patients in July 1, 2011., Aims: In this study, we describe the medical cost and utilization rates of antiviral therapy for CHB patients to explore the impact of the new partial reimbursement policy on the medical care cost, the composition, and antivirals utilization., Methods: Clinical and claims data of a retrospective cohort of 92,776 outpatients and 2,774 inpatients with non-cirrhotic CHB were retrieved and analyzed from You'an Hospital, Beijing between February 14, 2008 and December 31, 2012. The propensity score matching was used to adjust factors associated with the annual total cost, including age, gender, medical insurance type and treatment indicator., Results: Compared to patients who paid out-of-pocket, medical cost, especially antiviral costs increased greater among patients with medical insurance after July 1, 2011, the start date of reimbursement policy. Outpatients with medical insurance had 16% more antiviral utilization; usage increased 3% among those who paid out-of-pocket after the new partial reimbursement policy was implemented., Conclusions: Direct medical costs and antiviral utilization rates of CHB patients with medical insurance were higher than those from paid out-of-pocket payments, even after adjusting for inflation and other factors. Thus, a new partial reimbursement program may positively optimize the cost and standardization of antiviral treatment.

Background: Schizophrenia and bipolar disorder (BD) are psychiatric diseases that are commonly managed with antipsychotics. Treatment pathways are highly variable and no universal treatment guidelines are available. The primary objective of the Italian Burden of Illness in Schizophrenia and BD (IBIS) study was to describe pharmaco-utilisation of antipsychotic treatments and characteristics of patients affected by schizophrenia or BD. A secondary objective was to describe costs of illness for patients with schizophrenia or BD., Methods: IBIS was a multicentre, real-world, retrospective, observational cohort study based on data obtained from administrative databases of 16 Local Health Units in Italy (~7.5 million individuals). Patients with schizophrenia or BD ≥18 years of age treated with antipsychotics between 1 January 2008 and 31 December 2009 were included in the primary analysis. Pharmaco-utilisation data were gathered over a follow-up period of 12 months., Results: Patients with schizophrenia and BD received a wide variety of antipsychotic medications. The proportion of patients on antipsychotic monotherapy was 68% in patients with schizophrenia and 70% in patients with BD. In patients with schizophrenia, ~1/3 of patients receiving antipsychotic monotherapy also received mood stabilisers and/or antidepressants (34.7%) compared with over half of those on antipsychotic polytherapy (52.2%). In patients with BD, use of mood stabilisers and/or antidepressants was even higher; 76.9% of patients receiving antipsychotic monotherapy also received mood stabilisers and/or antidepressants compared with 85.5% of patients on antipsychotic polytherapy. Switch therapy was more frequent in patients with BD than in patients with schizophrenia, whereas add-on therapy was more frequent in patients with schizophrenia than in patients with BD. The mean total disease-related cost per patient per annum was higher in patients with schizophrenia (€4,157) than in patients with BD (€3,301). The number and cost of hospitalisations was higher in patients with BD, whereas the number and cost of nursing home stays was higher in patients with schizophrenia., Conclusion: Use of administrative databases has permitted retrieval of comprehensive information about therapeutic pathways, diagnostic history and costs in patients affected by schizophrenia or BD. A need for personalised treatment pathways has been described., Trial Registration: clinicaltrials.gov: NCT01392482 ; first received June 29, 2011.

Restrictive reimbursement policies-including those based on non-formulary drug status and prior authorizations-can create situations in which patients' use of prescription medications is not fully captured in administrative claims data. This can create bias in drug safety studies that depend solely on these data. An analysis in two Canadian provinces found that primary administrative databases captured only 61 % of dispensations of drugs for which restrictive reimbursement policies were in place. A subsequent simulation study found that, in certain circumstances bias due to exposure misclassification resulting from restrictive reimbursement policies can be quite large in analyses comparing outcomes between drug exposure groups. Investigators need to be knowledgeable about the data they analyze and know whether restrictive reimbursement policies are in place that might affect the capture of drugs of interest. It is also critical to understand the mechanisms by which restrictive reimbursement might cause bias in claims-based drug safety studies, the direction and magnitude of the potential bias, and strategies that could be used to mitigate such bias.

Background: Cost-containment strategies are required to deal with rising drug expenditure, also in oncology. Drug wastage related to the preparation of chemotherapy drugs for patients is costly, but solutions exist for optimizing the use of unconsumed anticancer drugs., Objective: Our pharmacy department makes use of a computerized drug storage bank, which records stability data and the amounts of unconsumed drugs available, and is connected to prescription software via an interface. We aimed to evaluate the real cost savings generated by this system., Method: We assessed the cost savings achieved with this system, for 37 different anticancer drugs, over a 1-year period. French drug pricing and the amounts of drugs from the storage bank potentially re-used were assessed., Results: The re-use of unconsumed anticancer drugs generated substantial cost savings, for nine drugs in particular: azacitidine, bevacizumab, bortezomib, cetuximab, docetaxel, liposomal doxorubicin, rituximab, topotecan and trastuzumab. Overall cost savings accounted for about 5 % of total anticancer drug expenditure at our hospital (8.5 M)., Conclusion: In medical hematology-oncology, drug wastage reduction and a computerized physician order entry system could be applied in routine practice at centralized drug-processing units, with significant financial benefits.

Introduction: Reducing any wastage, including that of medications, is a paramount objective in promoting appropriate utilisation of finite resources. The objective was to systematically review the published literature, the possible causative factors associated with medication wastage and the effectiveness of any interventions to reduce wastage., Method: A systematic review of studies published in English was identified from the following databases: Cumulative Index to Nursing and Allied Health Literature, Embase, Medline, PubMed, Science Citation Index and The Cochrane Library. Data extraction and critical appraisal was undertaken independently by two researchers., Results and Discussion: Title, abstract and full paper screening reduced the 14,157 studies to 42. A general definition of medication wastage was reported in one paper only. 'Medication changed', 'patient death', 'resolution of patient's condition' and 'expired medications' were most commonly cited reasons for wastage. Only two studies were identified reporting wastage as a research outcome measure following intervention., Conclusion: The systematic review has identified a limited literature on medication wastage with a lack of consistency of terms. There is a paucity of robust research focusing on the impact of healthcare interventions on outcomes around medication wastage.

Our objective was to rigorously evaluate the impact of an antimicrobial stewardship audit-and-feedback intervention, via a stepped-wedge randomized trial. An effective intensive care unit (ICU) audit-and-feedback program was rolled out to 6 non-ICU services in a randomized sequence. The primary outcome was targeted antimicrobial utilization, using a negative binomial regression model to assess the impact of the intervention while accounting for secular and seasonal trends. The intervention was successfully transitioned, with high volumes of orders reviewed, suggestions made, and recommendations accepted. Among patients meeting stewardship review criteria, the intervention was associated with a large reduction in targeted antimicrobial utilization (-21%, P = .004); however, there was no significant change in targeted antibiotic use among all admitted patients (-1.2%, P = .9), and no reductions in overall costs and microbiologic outcomes. An ICU day 3 audit-and-feedback program can be successfully expanded hospital-wide, but broader benefits on non-ICU wards may require interventions earlier in the course of treatment., (© The Author 2014.

Background: The assessment of volatile agents' consumption can be performed by weighing vapourisers before and after use. This method is technically demanding and unavailable for retrospective analysis of anaesthesia records. Therefore, a method based on calculations from fresh gas flow and agent concentration is presented here., Methods: The presented calculation method herein enables a precise estimation of volatile agent consumption when average fresh gas flows and volatile agent concentrations are known. A pre-condition for these calculations is the knowledge of the vapour amount deriving from 1 ml fluid volatile agent. The necessary formulas for these calculations and an example for a sevoflurane anaesthesia are presented., Results: The amount of volatile agent vapour deriving from 1 ml of fluid agent are for halothane 229 ml, isoflurane 195 ml, sevoflurane 184 m, and desflurane 210 ml. The constant for sevoflurane is used in a fictitious clinical case to exemplify the calculation of its consumption in daily routine resulting in a total expenditure of 23.6 ml liquid agent., Conclusions: By application of the presented specific volatile agent constants and equations, it becomes easy to calculate volatile agent consumption if the fresh gas flows and the resulting inhaled concentration of the volatile agent are known. By this method, it is possible to extract data about volatile agent consumption both ways: (1) retrospectively from sufficiently detailed and accurate anaesthesia recordings, as well as (2) by application of this method in a prospective setting. Therefore, this method is a valuable contribution to perform pharmacoeconomical surveys., (© 2014 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.)

In Germany a list was drawn up that included 83 potentially inappropriate drugs. The PRISCUS list published in 2010 was intended to highlight certain problems in the pharmakotherapy of elderly patients and serve as a support for improved medicine safety. Almost a third of the insurance portfolio of the HALLESCHE Krankenversicherung aged over 75 years takes drugs that are on the PRISCUS list. Benzodiazepine and Z-drugs are taken most frequently. The costs per insurant with potentially inappropriate medication are on average higher than for policyholders who do not take drugs on the PRISCUS list. The costs per insurant are rising, with an increase in the number of PRISCUS agents being taken as well. However, there is still no scientific proof that potentially inappropriate drugs lead to adverse drug events.

Objectives: To describe sales and sales patterns of veterinary antimicrobial agents in 25 European Union (EU)/European Economic Area (EEA) countries for 2011., Methods: Data on the sales of veterinary antimicrobial agents from 25 EU member states and EEA countries for 2011 were collected at package level (name, formulation, strength, pack size, number of packages sold) according to a standardized protocol and template and presented in a harmonized manner. These data were calculated to express amounts sold, in metric tonnes, of active ingredient of each package. A population correction unit (PCU) was applied as a proxy for the animal biomass potentially treated with antimicrobial agents. The indicator used to express sales was milligrams of active substance per PCU., Results: Substantial variations in the sales patterns and in the magnitude of sales of veterinary antimicrobial agents, expressed as mg/PCU, between the countries were observed. The proportion of sales, in mg/PCU, of products applicable for treatment of groups or herds of animals (premixes, oral powders and oral solution) varied considerably between the countries., Conclusions: Some countries reported much lower sales of veterinary antimicrobial agents than others, when expressed as mg/PCU. Sales patterns varied between countries, particularly with respect to pharmaceutical forms. Further studies are needed to understand the factors that explain the observed differences., (© The Author 2014.

Two oral antiplatelet agents have been recently introduced for acute coronary syndromes indication providing alternatives for dual therapy with aspirin and clopidogrel. In fact, worldwide prasugrel has been on the market for four years, and ticagrelor for over two years. Despite declared benefits over clopidogrel, including hypothetical cost saving advantages, in real life, the clinical utilisation of both agents is small. Generic clopidogrel, and price differences are claimed as major obstacles to prevent broader prasugrel and ticagrelor use. However, these economic difficulties are barely supported by available evidence, and served mostly to protect questionable management spending, as an exuse to explain why in reality cardiologists are so sceptical about both novel agents, and to convince the sharehoders that their money is not wasted, misleading the owners with regard to future success. Importantly, brand Plavix® is used worldwide 5-10 times more often than new agents, despite heavy generic competition. The future of prasugrel outside Japan, where much lower reasonable dose will be used is not impressive due to lack of further outcome studies, negative results of the latest trials, and less than four years left before patent expiration. The fate of ticagrelor will depend on verification of deaths numbers in the ongoing United States Department of Justice PLATO investigation, and confirmation of the mortality benefit in the PEGASUS TIMI-54 trial.

In Italy, prescription drug costs represent approximately 17% of total public health expenditures. Older adults commonly use multiple drugs and, for this reason, this population is responsible for a large portion of drug-related costs. In 2012, public expenditure for pharmaceuticals in primary care exceeded 11 billion Euros (approximately 15.2 billion US $), and older adults aged 65 or older accounted for more than 60% of these costs. Recently, increased attention has been focused on studies aimed at monitoring drug use and evaluating the appropriateness of drug prescribing in older adults. In this article, we examined studies that assessed these issues in different settings at a national level. Specifically, results of surveys of prescription drug use in primary care (OsMED), hospital (GIFA, CRIME, and REPOSI) and long-term care (ULISSE and SHELTER) settings are reviewed. Overall, these studies showed that the quality of drug prescribing in older patients is far from optimal. This leads to an increased risk of negative health outcomes and increased health care costs. Data from these studies are valuable, not only to monitor drug use, but also to target interventions aimed at improving the quality of prescribing. Translating the findings of clinical research and monitoring programs will be challenging, but it will lead to quantifiable improvements in the quality of drug prescribing at a national level., (Copyright © 2014 AMDA – The Society for Post-Acute and Long-Term Care Medicine.
