Cost-effectiveness of implantable ventricular assist devices in older children with stable, inotrope-dependent dilated cardiomyopathy.

BACKGROUND: In a stable, inotrope-dependent pediatric patient with dilated cardiomyopathy, we evaluated the cost-effectiveness of continuous-flow VAD implantation compared to a watchful waiting approach using chronic inotropic therapy. METHODS: We used a state-transition model to estimate the costs and outcomes of 14-year-old (INTERMACS profile 3) patients receiving either VAD or watchful waiting. We measured benefits in terms of lifetime QALYs gained. Model inputs were taken from the literature. We calculated the ICER, or the cost per additional QALY gained, of VADs and performed multiple sensitivity analyses to test how our assumptions influenced the results. RESULTS: Compared to watchful waiting, VADs produce 0.97 more QALYs for an additional $156 639, leading to an ICER of $162 123 per QALY gained from a healthcare perspective. VADs have 17% chance of being cost-effective given a cost-effectiveness threshold of $100 000 per QALY gained. Sensitivity analyses suggest that VADs can be cost-effective if the costs of implantation decrease or if hospitalization costs or mortality among watchful waiting patients is higher. CONCLUSIONS: As a bridge to transplant, VADs provide a health benefit to children who develop stable, inotrope-dependent heart failure, but immediate implantation is not yet a cost-effective strategy compared to watchful waiting based on commonly used cost-effectiveness thresholds. Early VAD support can be cost-effective in sicker patients and if device implantation is cheaper. In complex conditions such as pediatric heart failure, cost-effectiveness should be just one of many factors that inform clinical decision-making.

Economic analysis of intermittent intravenous outpatient treatment with levosimendan in advanced heart failure in Spain.

INTRODUCTION AND OBJECTIVES: Advanced heart failure (HF) leads to high hospitalization and mortality rates. The LION-HEART study was a randomized, placebo-controlled clinical trial that evaluated the safety and efficacy of intravenous administration of intermittent doses of levosimendan in outpatients with advanced HF. The aim of the present study was to perform a cost analysis to determine whether the lower rate of hospitalizations for HF, observed in patients treated with levosimendan in the LION-HEART study, can generate savings for the Spanish national health system compared with the option of not treating patients with advanced HF. METHODS: An economic model was used that included IC hospitalization rates from the LION-HEART study, the costs of hospitalization due to HF and those of the acquisition and intravenous administration of levosimendan. The time horizon of the analysis was 12 months. Two analyses were carried out, one deterministic and the other probabilistic (second-order Monte Carlo simulation). RESULTS: In the deterministic analysis, the total saving for each patient treated with levosimendan would amount to-€698.48. In the probabilistic analysis, the saving per patient treated with levosimendan would be-€849.94 (95%CI, €133.12 to-€2,255.31). The probability of savings with levosimendan compared with the no treatment option would be 94.8%. CONCLUSIONS: Intermittent ambulatory treatment with levosimendan can generate savings for the Spanish national health system compared with the option of not treating patients with advanced HF.

Internet Marketing of Cardioprotective Dietary Supplements.

Objectives: Considering high prevalence of use of dietary supplements and their easy access on the internet, the aim of this research was to examine and assess the prevalence of the internet marketing of heart-protective supplements as the most popular supplements of today, and to investigate the quality and quantity of information that are available to consumers on the sale websites. Design: Three major search engines (Google, Yahoo, and Bing) and keywords "cardiovascular supportive supplements online buy" were used to identify websites that sell cardioprotective dietary supplements. Content of first 50 listed websites in each engine was evaluated for its compliance with regulatory acts while information about supplements' efficacy and safety was compared with the results of the latest scientific research. Results: Of a total of 150 listed websites, 89 selling supplements for the specific indication underwent further analysis. The most commonly registered cardioprotective dietary supplements on the internet were supplements based on omega-3 fatty acids (omega-3) (57 websites, 64.05%). Related to the websites selling omega-3 supplements, risk reduction claims were presented at 23 (40.35%), whereas structure or function claims were present at 50 (87.72%) analyzed websites, but followed with Food and Drug Administration disclaimer only on 68.00% of them. Information about adverse effects were rarely pointed out (1 website, 1.75%) unlike warnings, which were significantly more available to consumers (38, 66.67%). Conclusions: According to obtained results, most of the analyzed websites that sell omega-3 supplements did not contain all important medical information required by Dietary Supplement Health and Education Act. Since use of internet marketing is in expansion and since consumers have no access to relevant medical information about dietary supplements on the selling websites, there is a clear need for better quality control of websites and greater public awareness of these widely used products.

Levosimendan in patients with reduced left ventricular function undergoing isolated coronary or valve surgery.

OBJECTIVE: In the Levosimendan in Patients with Left Ventricular Systolic Dysfunction Undergoing Cardiac Surgery Requiring Cardiopulmonary Bypass (LEVO-CTS) trial, no differences in clinical outcomes were observed between levosimendan and placebo in a broad population of patients undergoing cardiac surgery. In previous studies, the benefits of levosimendan were most clearly evident in patients undergoing isolated coronary artery bypass grafting (CABG) surgery. In a prespecified analysis of LEVO-CTS, we compared treatment-related outcomes and costs across types of cardiac surgical procedures. METHODS: Overall, 563 (66.4%) patients underwent isolated CABG, 97 (11.4%) isolated valve, and 188 (22.2%) combined CABG/valve surgery. Outcomes included the co-primary 4-component composite (30-day mortality, 30-day renal replacement, 5-day myocardial infarction, or 5-day mechanical circulatory support), the 2-component composite (30-day mortality or 5-day mechanical circulatory support), 90-day mortality, low cardiac output syndrome (LCOS), and 30-day medical costs. RESULTS: The 4- and 2-component outcomes were not significantly different with levosimendan and placebo in patients undergoing CABG (15.2% vs 19.3% and 7.8% vs 10.4%), valve (49.0% vs 33.3% and 22.4% vs 2.1%), or combined procedures (39.6% vs 35.9% and 24.0% vs 19.6%). Ninety-day mortality was lower with levosimendan in isolated CABG (2.1% vs 7.9%; hazard ratio [HR], 0.26; 95% confidence interval [CI], 0.11-0.64), but not significantly different in valve (8.3% vs 2.0%; HR, 4.10; 95% CI, 0.46-36.72) or combined procedures (10.4% vs 7.6%; HR, 1.39; 95% CI, 0.53-3.64; interaction P = .011). LCOS (12.0% vs 22.1%; odds ratio, 0.48; 95% CI, 0.30-0.76; interaction P = .118) was significantly lower in levosimendan-treated patients undergoing isolated CABG. Excluding study drug costs, median and mean 30-day costs were $53,707 and $65,852 for levosimendan and $54,636 and $67,122 for placebo, with a 30-day mean difference (levosimendan - placebo) of -$1270 (bootstrap 95% CI, -$8722 to $6165). CONCLUSIONS: Levosimendan was associated with lower 90-day mortality and LCOS in patients undergoing isolated CABG, but not in those undergoing isolated valve or combined CABG/valve procedures.

[Economic assessment of dexrazoxane in prophylaxis of cardiotoxicity in children undergoing chemotherapy with anthracyclines]. / Avaliação econômica do uso de dexrazoxano na profilaxia de cardiotoxicidade em crianças em tratamento quimioterápico com antraciclinas.

Cancer in individuals 0 to 19 years of age is considered rare when compared to incidence in older age brackets, and is estimated at 2% to 3% of all malignant tumors recorded in Brazil. The use of anthracyclines is frequently associated with cardiotoxicity, and these drugs are part of approximately 60% of treatment protocols in pediatric oncology. Among the existing strategies for the prevention of cardiotoxicity, dexrazoxane obtained favorable results based on intermediate outcomes (biochemical markers and echocardiographic parameters). This study was based on a cost-effectiveness assessment comparing the use of dexrazoxane in different populations, besides an assessment of the budget impact from the technology's potential incorporation. The patient's lifetime was used as the timeline, and the analysis was performed from the perspective of the Brazilian Unified National Health System (SUS). A budget impact analysis was also performed for each technology. After a literature search, a Markov model was developed, capable of comparing the use of dexrazoxane in six profiles of patients at risk of developing cardiotoxicity. Use of the drug in children under 5 years of age proved to be the most cost-effective alternative (incremental cost effectiveness ratio - ICER of BRL 6,156.96), followed by use in all patients (ICER of BRL 58,968.70). If the price decreased to less than BRL 250.00 per vial, the alternative of using the drug in all children would become the most cost-effective. The budget impact at 5 years was BRL 30,622,404.81 for use only in children under 5 years of age. Using the technology in all the children could produce an incremental impact of BRL 94,352,898.77.

Continuous Cardiac Inotropes in Patients With End-Stage Heart Failure: An Evolving Experience.

Heart failure (HF) experts recommend initiation of continuous inotrope therapy, such as milrinone or dobutamine, for clinically decompensating patients with stage D HF. Although originally intended to serve solely as a bridge to more definitive surgical therapies, more and more patients are receiving inotrope therapy for purely palliative purposes. In these cases, questions arise regarding care at the end of life. What criteria determine ongoing clinical benefit? Should the inotrope be continued until death? Should inotrope dosing be increased within recommended guidelines to improve symptoms? What is the role of inotropes in hospice care? Here, we describe such a case as a springboard to contemplate the evolving role of inotrope therapies and how hospice and palliative providers may interface with this rapidly developing face of advanced HF care.

Cost-Effectiveness of Left Ventricular Assist Devices in Ambulatory Patients With Advanced Heart Failure.

OBJECTIVES: This study assessed the cost-effectiveness of left ventricular assist devices (LVADs) as destination therapy in ambulatory patients with advanced heart failure. BACKGROUND: LVADs improve survival and quality of life in inotrope-dependent heart failure, but data are limited as to their value in less severely ill patients. METHODS: We determined costs of care among Medicare beneficiaries before and after LVAD implantation from 2009 to 2010. We used these costs and efficacy data from published studies in a Markov model to project the incremental cost-effectiveness ratio (ICER) of destination LVAD therapy compared with that of medical management. We discounted costs and benefits at 3% annually and report costs as 2016 U.S. dollars. RESULTS: The mean cost of LVAD implantation was $175,420. The mean cost of readmission was lower before LVAD than after ($12,377 vs. $19,465, respectively; p < 0.001), while monthly outpatient costs were similar ($3,364 vs. $2,974, respectively; p = 0.54). In the lifetime simulation model, LVAD increased quality-adjusted life-years (QALYs) (4.41 vs. 2.67, respectively), readmissions (13.03 vs. 6.35, respectively), and costs ($726,200 vs. $361,800, respectively) compared with medical management, yielding an ICER of $209,400 per QALY gained and $597,400 per life-year gained. These results were sensitive to LVAD readmission rates and outpatient care costs; the ICER would be $86,900 if these parameters were 50% lower. CONCLUSIONS: LVADs in non-inotrope-dependent heart failure patients improved quality of life but substantially increased lifetime costs because of frequent readmissions and costly follow-up care. LVADs may provide good value if outpatient costs and adverse events can be reduced.

Levosimendan: new indications and evidence for reduction in perioperative mortality?

PURPOSE OF REVIEW: In the last years, the perioperative use of levosimendan in cardiac surgery patients is spreading. Moreover, newer indications have been suggested such as the treatment of sepsis-associated myocardial dysfunction. In the present review, we discuss the most recent evidences in these settings. RECENT FINDINGS: Levosimendan has been seemingly confirmed to reduce mortality in patients undergoing cardiac surgery. In particular, it appears to be the only inotropic drug to have a favorable effect on survival in any clinical setting. Moreover, levosimendan has been shown to exert a cardioprotective action and to reduce acute kidney injury, renal replacement therapy, and ICU stay in cardiac surgery patients. Finally, levosimendan has been suggested to reduce mortality in patients with severe sepsis and to improve renal outcomes in critically ill patients. SUMMARY: Although a strong rationale likely exists to use levosimendan in the setting of perioperative and critical care medicine, evidence mainly comes from small and often poor-quality randomized clinical trials, whose results acquire significance only when pooled in meta-analyses. Moreover, some aspects related to which subgroups of patients may derive the most benefits from receiving levosimendan, to the optimal timing of administration, and to the potential adverse effects need to be further clarified. Important insights will be hopefully provided soon by the several large multicenter investigations which are currently ongoing.

Real-world cost effectiveness of MitraClip combined with Medical Therapy Versus Medical therapy alone in patients with moderate or severe mitral regurgitation.

BACKGROUND: We evaluated the real-world cost-effectiveness of the MitraClip system (Abbott Vascular Inc., Menlo Park, CA) plus medical therapy for patients with moderate/severe mitral regurgitation, as compared with medical therapy (MT) alone. METHODS: Clinical records of patients with moderate to severe functional mitral regurgitation treated with MitraClip (N=232) or with MT (N=151) were collected and outcome analyzed with propensity score adjustment to reduce selection bias. Twelve-month outcomes were modeled over a lifetime horizon to conduct a cost-effectiveness analysis, in the payer's perspective. Costs and benefits were discounted at an annual rate of 3.5%. RESULTS: After propensity score adjustment, the average treatment effect was -9.5% probability of dying at 12months and, following lifetime modeling, 3.35±0.75 incremental life years and 3.01±0.57 incremental quality-adjusted life years. MitraClip contributed to a higher decrease in re-hospitalizations at 12months (difference=-0.54±0.08) and generated a more likely improvement in the New York Heart Association (NYHA) class at 12months versus NYHA at enrollment. Incremental costs, adapted to five possible scenarios, ranged from 14,493 to 29,795 € contributing to an incremental cost-effectiveness ratio ranging from 4796 to 7908 €. CONCLUSIONS: Compared to MT alone and given conventional threshold values, MitraClip can be considered a cost-effective procedure. The cost-effectiveness of MitraClip is in line or superior to the one of other non-pharmaceutical strategies for heart failure.

Cost-benefits of incorporating levosimendan into cardiac surgery practice: German base case.

OBJECTIVE: To evaluate the cost-benefit of using levosimendan compared with dobutamine, in the perioperative treatment of patients undergoing cardiac surgery who require inotropic support. METHODS: A two-part Markov model was designed to simulate health-state transitions of patients undergoing cardiac surgery, and estimate the short- and long-term health benefits of treatment. Hospital length of stay (LOS), mortality, medication, and adverse events were key clinical- and cost-inputs. Cost-benefits were evaluated in terms of costs and bed stays within the German healthcare system. Drug prices were calculated from the German Drug Directory (€/2014) and published literature, with a 3% annual discount rate applied. The base case analysis was for a 1-year time horizon. RESULTS: The use of levosimendan vs dobutamine was associated with cost savings of €4787 per patient from the German hospital perspective due to reduced adverse events and shorter hospital LOS, leading to increased bed capacity and hospital revenue. LIMITATIONS: A pharmacoeconomic calculation for the specific situation of the German healthcare system that is based on international clinical trial carries a substantial risk of disregarding potentially relevant but unknown confounding factors (i.e., ICU-staffing, co-medications, standard-ICU care vs fast-tracking, etc.) that may either attenuate or increase the outcome pharmacoeconomic effects of a drug; however, since these conditions would also apply for patients treated with comparators, their net effects may not necessarily influence the conclusions. CONCLUSIONS: The use of levosimendan in patients undergoing cardiac surgery who require inotropic support appears to be cost-saving. The results of the analysis provide a strong rationale to run local clinical studies with pharmacoeconomic end-points which would allow a much more precise computation of the benefits of levosimendan.

Potential economic consequences of a cardioprotective agent for patients with myocardial infarction: modelling study.

OBJECTIVE: To investigate the cost-effectiveness of a hypothetical cardioprotective agent used to reduce infarct size in patients undergoing percutaneous coronary intervention (PCI) after anterior ST-elevation myocardial infarction. DESIGN: A cost-utility analysis using a Markov model. SETTING: The National Health Service in the UK. PATIENTS: Patients undergoing PCI after anterior ST-elevation myocardial infarction. INTERVENTIONS: A cardioprotective agent given at the time of reperfusion compared to no cardioprotection. We assumed the cardioprotective agent (given at the time of reperfusion) would reduce the risk and severity of heart failure (HF) after PCI and the risk of mortality after PCI (with a relative risk ranging from 0.6 to 1). The costs of the cardioprotective agent were assumed to be in the range £1000-4000. MAIN OUTCOME MEASURES: The incremental costs per quality-adjusted life-year (QALY) gained, using 95% CIs from 1000 simulations. RESULTS: Incremental costs ranged from £933 to £3820 and incremental QALYs from 0.04 to 0.38. The incremental cost-effectiveness ratio (ICER) ranged from £3311 to £63 480 per QALY gained. The results were highly dependent on the costs of a cardioprotective agent, patient age, and the relative risk of HF after PCI. The ICER was below the willingness-to-pay threshold of £20 000 per QALY gained in 71% of the simulations. CONCLUSIONS: A cardioprotective agent that can reduce the risk of HF and mortality after PCI has a high chance of being cost-effective. This chance depends on the price of the agent, the age of the patient and the relative risk of HF after PCI.

Pharmaco-economics of levosimendan in cardiology: a European perspective.

INTRODUCTION: Heart failure places a significant economic burden on health care. Acute heart failure requires hospitalization and often frequent re-hospitalization in expensive wards where vasoactive rescue therapy is often added on top of standard medications. In these lean times, there is a growing need for cost-effective therapeutic options that supply superior support and in addition shorten the length of stay in hospital and reduce re-hospitalization rates. The inodilator levosimendan represents the latest addition to the vasoactive treatments of acute heart failure patients, and it appears to meet these expectations. Our aim was to answer the question whether the treatment efficacy of levosimendan - when selected as therapy for patients hospitalized for acute heart failure - brings savings to hospitals in various European countries representing different economies. METHODS AND RESULTS: We took a conservative approach and selected some a fortiori arguments to simplify the calculations. We selected seven European countries to represent different economies: Italy, Spain, Greece, Germany, Sweden, Finland and Israel. Data on the costs of medications and on the cost per day were collected and fed in a simple algorithm to detect savings. These saving varied from country to country, from a minimum of €0.50 in Germany to a maximum of €354.64 in Sweden. CONCLUSIONS: The use of levosimendan as a therapy for patients hospitalized for acute heart failure provides a net saving to hospitals driven by a reduction in the length of hospital stay. This finding is true in each of the countries considered in this study.

Incremental cost-effectiveness of dobutamine stress cardiac magnetic resonance imaging in patients at intermediate risk for coronary artery disease.

AIMS: The effectiveness of stress cardiac magnetic resonance (CMR) as a gatekeeper for coronary angiography (CA) has been established. Level five HTA studies according to the hierarchical model of diagnostic test evaluation are not available. METHODS: This cohort study included 1,158 consecutive patients (mean age 63 ± 11 years, 42 % women) presenting at our institution between January 1, 2003 and December 31, 2004 with suspected coronary artery disease (CAD) for an elective CA. The patients were assessed for eligibility and propensity score matching was applied to address selection bias regarding the patients' allocation to CMR or direct CA. Median patient follow-up was 7.9 years (95 % CI 7.8-8.0 years). The primary effect was calculated as relative survival difference. The cost unit calculation (per patient) at our institute was the source of costs. RESULTS: Survival was similar in CMR and CA (p = 0.139). Catheterizations ruling out CAD were significantly reduced by the CMR gate-keeper strategy. Patients with prior CMR had significantly lower costs at the initial hospital stay and at follow-up (CMR vs. CA, initial: 2,904 vs. 3,421, p = 0.018; follow-up: 2,045 vs. 3,318, p = 0.037). CMR was cost-effective in terms of a contribution of 12,466 per life year to cover a part of the CMR costs. CONCLUSION: Stress CMR prior to CA was saving 12,466 of hospital costs per life year. Lower costs at follow-up suggest sustained cost-effectiveness of the CMR-guided strategy.

Long-term use and cost-effectiveness of secondary prevention drugs for heart disease in Western Australian seniors (WAMACH): a study protocol.

INTRODUCTION: Secondary prevention drugs for cardiac disease have been demonstrated by clinical trials to be effective in reducing future cardiovascular and mortality events (WAMACH is the Western Australian Medication Adherence and Costs in Heart disease study). Hence, most countries have adopted health policies and guidelines for the use of these drugs, and included them in government subsidised drug lists to encourage their use. However, suboptimal prescribing and non-adherence to these drugs remains a universal problem. Our study will investigate trends in dispensing patterns of drugs for secondary prevention of cardiovascular events and will also identify factors influencing these patterns. It will also assess the clinical and economic consequences of non-adherence and the cost-effectiveness of using these drugs. METHODS AND ANALYSIS: This population-based cohort study will use longitudinal data on almost 40,000 people aged 65 years or older who were hospitalised in Western Australia between 2003 and 2008 for coronary heart disease, heart failure or atrial fibrillation. Linking of several State and Federal government administrative data sets will provide person-based information on drugs dispensed precardiac and postcardiac event, reasons for hospital admission, emergency department visits, mortality and medical visits. Dispensed drug trends will be described, drug adherence measured and their association with future all-cause/cardiovascular events will be estimated. The cost-effectiveness of these long-term therapies for cardiac disease and the impact of adherence will be evaluated.

Clinical effectiveness and cost-effectiveness of second- and third-generation left ventricular assist devices as either bridge to transplant or alternative to transplant for adults eligible for heart transplantation: systematic review and cost-effectiveness model.

BACKGROUND: Advanced heart failure (HF) is a debilitating condition for which heart transplant (HT) offers the best treatment option. However, the supply of donor hearts is diminishing and demand greatly exceeds supply. Ventricular assist devices (VADs) are surgically implanted pumps used as an alternative to transplant (ATT) or as a bridge to transplant (BTT) while a patient awaits a donor heart. Surgery and VADs are costly. For the NHS to allocate and deliver such services in a cost-effective way the relative costs and benefits of these alternative treatments need to be estimated. OBJECTIVES: To investigate for patients aged ≥ 16 years with advanced HF eligible for HT: (1) the clinical effectiveness and cost-effectiveness of second- and third-generation VADs used as BTT compared with medical management (MM); and (2) the clinical effectiveness and cost-effectiveness of second- and third-generation VADs used as an ATT in comparison with their use as BTT therapy. DATA SOURCES: Searches for clinical effectiveness studies covered years from 2003 to March 2012 and included the following data bases: MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, EMBASE, Cochrane Database of Systematic Reviews (CDSR), Database of Abstracts of Reviews of Effects (DARE), NHS Economic Evaluation Database (NHS EED), HTA databases [NHS Centre for Reviews and Dissemination (CRD)], Science Citation Index and Conference Proceedings (Web of Science), UK Clinical Research Network (UKCRN) Portfolio Database, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO and National Library of Medicine (NLM) Gateway, Cochrane Central Register of Controlled Trials (CENTRAL), Current Controlled Trials and ClinicalTrials.gov. Reference lists of relevant articles were checked, and VAD manufacturers' websites interrogated. For economic analyses we made use of individual patient data (IPD) held in the UK Blood and Transplant Database (BTDB). REVIEW METHODS: Systematic reviews of evidence on clinical effectiveness and cost-effectiveness of second- and third-generation US Food and Drug Administration (FDA) and/or Conformité Européenne (CE) approved VADs. Publications from the last 5 years with control groups, or case series with 50 or more patients were included. Outcomes included survival, functional capacity (e.g. change in New York Heart Association functional classification), quality of life (QoL) and adverse events. Data from the BTDB were obtained. A discrete-time, semi-Markov, multistate model was built. Deterministic and probabilistic methods with multiple sensitivity analyses varying survival, utilities and cost inputs to the model were used. Model outputs were incremental cost-effectiveness ratios (ICERs), cost/quality-adjusted life-years (QALYs) gained and cost/life-year gained (LYG). The discount rate was 3.5% and the time horizon varied over 3 years, 10 years and lifetime. RESULTS: Forty publications reported clinical effectiveness of VADs and one study reported cost-effectiveness. We found no high-quality comparative empirical studies of VADs as BTT compared with MM or as ATT compared with BTT. Approximately 15-25% of the patients receiving a device had died by 12 months. Studies reported the following wide ranges for adverse events: 4-27% bleeding requiring transfusion; 1.5-40% stroke; 3.3-48% infection; 1-14% device failure; 3-30% HF; 11-32% reoperation; and 3-53% renal failure. QoL and functional status were reported as improved in studies of two devices [HeartMate II (HMII; Thoratec Inc., Pleasanton, CA, USA) and HeartWare (HW; HeartWare Inc., Framingham, MA, USA)]. At 3 years, 10 years and lifetime, the ICERs for VADs as BTT compared with MM were £122,730, £68,088 and £55,173 respectively. These values were stable to changes in survival of the MM group. Both QoL and costs were reduced by VADs as ATT compared with VADs as BTT giving ICERs in south-west quadrant of the cost effectiveness plain (cost saving/QALY sacrificed) of £353,467, £31,685 and £20,637 over the 3 years, 10 years and lifetime horizons respectively. Probabilistic analyses yielded similar results for both research questions. LIMITATIONS: Conclusions about the clinical effectiveness were limited by the lack of randomised controlled trials (RCTs) comparing the effectiveness of different VADs for BTT or comparing BTT with any alternative treatment and by the overlapping populations in published studies. Although IPD from the BTDB was used to estimate the cost-effectiveness of VADs compared with MM for BTT, the lack of randomisation of populations limited the interpretation of this analysis. CONCLUSIONS: At 3 years, 10 years and lifetime the ICERs for VADs as BTT compared with MM are higher than generally applied willingness-to-pay thresholds in the UK, but at a lifetime time horizon they approximate threshold values used in end of life assessments. VADs as ATT have a reduced cost but cause reduced QALYs relative to BTT. Future research should direct attention towards two areas. First, how any future evaluations of second- or third-generation VADs might be conducted. For ethical reasons a RCT offering equal probability of HT for each group would not be feasible; future studies should fully assess costs, long-term patient survival, QoL, functional ability and adverse events, so that these may be incorporated into economic evaluation agreement on outcomes measures across future studies. Second, continuation of accurate data collection in the UK database to encompass QoL data and comparative assessment of performance with other international centres.

A price and use comparison of generic versus originator cardiovascular medicines: a hospital study in Chongqing, China.

BACKGROUND: Developed countries use generic competition to contain pharmaceutical expenditure. China, as a developing and transitional country, has not yet deemed an increase in the use of generic products as important; otherwise, much effort has been made to decrease the drug prices. This paper aims to explore dynamically the price and use comparison of generic and originator drugs in China, and estimate the potential savings of patients from switching originator drugs to generics. METHODS: A typical hospital in Chongqing, China, was selected to examine the price and use comparisons of 12 cardiovascular drugs from 2006 to 2011. RESULTS: The market share of the 12 generic medicines studied in this paper was 34.37% for volume and 31.33% for value in the second half of 2011. The price ratio of generic to originator drugs was between 0.34 and 0.98, and the volume price index of originators to generics was 1.63. The potential savings of patients from switching originator drugs to generics is 65%. CONCLUSION: The market share of the generics was lowering and the weighted mean price kept increasing in face of the strict price control. Under the background of hospitals both prescribing and dispensing medicines, China's comprehensive healthcare policy makers should take measures from supply and demand sides to promote the consumption of generic medicines.

The economic impact of Medicare Part D on congestive heart failure.

Medicare Part D has had important implications for patient outcomes and treatment costs among beneficiaries with congestive heart failure (CHF). This study finds that improved medication adherence associated with expansion of drug coverage under Part D led to nearly $2.6 billion in reductions in medical expenditures annually among beneficiaries diagnosed with CHF and without prior comprehensive drug coverage, of which over $2.3 billion was savings to Medicare. Further improvements in adherence could potentially save Medicare another $1.9 billion annually, generating upwards of $22.4 billion in federal savings over 10 years.
