Impact of apixaban vs low molecular weight heparin/vitamin k antagonist on hospital resource use in patients with venous thromboembolism.

BACKGROUND: The clinical and economic benefits associated with apixaban treatment have been established in clinical trials and published economic evaluations. The benefits associated with apixaban could extend to improving hospital efficiencies, potentially influencing hospital resource use, and bed days. The objective of this study is to estimate the impact of 6-month treatment with apixaban vs low molecular weight heparin/vitamin k antagonist (LMWH/VKA) on hospital resource use among patients with venous thromboembolism (VTE). METHODS: A model was developed to assess the impact of apixaban vs LMWH/VKA for treatment of VTE and prevention of recurrences on hospital resource use and costs. Resource use items included total hospitalizations, length of stay (LOS), and emergency department (ED) visits, estimated for all incident VTE patients in the UK over a 5-year time horizon. Rates of hospitalizations, ED visits, and LOS associated with recurrent VTE, major, and clinically relevant non-major bleeding were obtained from the AMPLIFY trial; costs were obtained from UK published sources. RESULTS: Over a 5-year time horizon, the model predicted that, compared to 6 months of LMWH/VKA, 6 months of apixaban led to 3,954 fewer hospitalizations (consisting of 2,341 fewer new admissions and 1,613 fewer re-admissions) and 32,214 fewer bed days, among 332,607 incident VTE patients. ED visits were reduced by 1,582. The reduction in hospital resource use led to a cost saving of ∼£4.5 million in a market of patients treated with apixaban as compared to a market treated with LMWH/VKA. Sensitivity analysis indicated these findings were robust over a wide range of inputs. CONCLUSIONS: 6-month treatment with apixaban for treatment of VTE and prevention of recurrences on hospital resource use led to a reduction in hospitalizations and LOS in comparison to LMWH/VKA. These findings can help the efforts in reducing the growing burden of preventable re-admissions to hospitals.

The costs of managing genital warts in the UK by devolved nation: England, Scotland, Wales and Northern Ireland.

Genital warts, 90% of which are caused by human papillomavirus types 6 and 11, are a significant problem in the UK. The cost of managing genital warts was previously estimated at £52.4 million for 2010. The objective of this study was to estimate the cost of genital warts management up to 2012 in the UK and by jurisdiction. Population statistics and the number of reported genital warts cases in genito-urinary medicine clinics were obtained and extrapolated to 2012. Cases of genital warts treated in primary care were estimated from The Health Improvement Network database. The number of visits and therapy required were estimated by genito-urinary medicine experts. Costs were obtained from the appropriate national tariffs. The model estimated there were 220,875 genital warts cases in the UK in 2012, costing £58.44 million (£265/patient). It estimated 157,793 cases in England costing £41.74 million; 7468 cases in Scotland costing £1.90 million; 7095 cases in Wales costing £1.87 million; and 3621 cases in Northern Ireland costing £948,000. The full National Health Service costs for the management of genital warts have never previously been estimated separately for each jurisdiction. Findings reveal a significant economic burden, which is important to quantify when understanding the value of quadrivalent human papilloma virus vaccination.

Stroke prevention in patients with atrial fibrillation in France: comparative cost-effectiveness of new oral anticoagulants (apixaban, dabigatran, and rivaroxaban), warfarin, and aspirin.

OBJECTIVES: To conduct an economic evaluation of the currently prescribed treatments for stroke prevention in patients with non-valvular atrial fibrillation (NVAF) including warfarin, aspirin, and novel oral anticoagulants (NOACs) from a French payer perspective. METHODS: A previously published Markov model was adapted in accordance to the new French guidelines of the Commission for Economic Evaluation and Public Health (CEESP), to adopt the recommended efficiency frontier approach. A cohort of patients with NVAF eligible for stroke preventive treatment was simulated over lifetime. Clinical events modeled included strokes, systemic embolism, intracranial hemorrhage, other major bleeds, clinically relevant non-major bleeds, and myocardial infarction. Efficacy and bleeding data for warfarin, apixaban, and aspirin were obtained from ARISTOTLE and AVERROES trials, whilst efficacy data for other NOACs were from published indirect comparisons. Acute medical costs were obtained from a dedicated analysis of the French national hospitalization database (PMSI). Long-term medical costs and utility data were derived from the literature. Univariate and probabilistic sensitivity analyses were performed to assess the robustness of the model projections. RESULTS: Warfarin and apixaban were the two optimal treatment choices, as the other five treatment strategies including aspirin, dabigatran 110 mg, dabigatran in sequential dosages, dabigatran 150 mg, and rivaroxaban were strictly dominated on the efficiency frontier. Further, apixaban was a cost-effective alternative vs warfarin with an incremental cost of €2314 and an incremental quality-adjusted life year (QALY) of 0.189, corresponding to an incremental cost-effectiveness ratio (ICER) of €12,227/QALY. CONCLUSIONS: Apixaban may be the most economically efficient alternative to warfarin in NVAF patients eligible for stroke prevention in France. All other strategies were dominated, yielding apixaban as a less costly yet more effective treatment alternative. As formally requested by the CEESP, these results need to be verified in a French clinical setting using stroke reduction and bleeding safety observed in real-life patient cohorts using these anticoagulants.

The cost of managing genital warts in the UK.

The national cost of managing genital warts (GWs) in the UK has not been fully estimated, yet is required to inform decisions on vaccination against human papillomavirus. This study estimated the 2010 UK costs based on secondary genitourinary (GU) medicine clinic data from the Health Protection Agency (HPA) and primary care data from the Health Improvement Network database. Extrapolating data to 2010 resulted in 173,077 GU medicine clinic and 16,782 primary care GW episodes. Using treatment patterns obtained from key opinion leaders and tariffs from National Health Service Payment by Results (NHS PbR), the national costs were estimated at £52.4 million: £276 per treated GW episode.
