Use of the incremental cost-effectiveness ratio for decision-making policies-what is the problem? A perspective paper.

INTRODUCTION: Drug reimbursement decisions that spark public controversy are potential signals that processes used to reach such decisions do not adequately reflect society's goals. Such controversial decisions appear to be a characteristic of Quality-Adjusted Life Year (QALY)-based Incremental Cost Effectiveness Ratio (ICER)-dominated decision-making systems. QALY-based ICER-heavy systems have several known weaknesses that lead to individual and societal preferences being either ignored or considered in an unsystematic and inconsistent manner. AREAS COVERED: We reprise some of the key inadequacies of QALY-based ICER analyses and suggest that there are other means including multicriteria decision analysis (MCDA) and cost-benefit analysis based on willingness to pay (WTP) measures by which to partially mitigate these weaknesses. EXPERT OPINION: For long, the inadequacies of QALY-based ICER-heavy decision-making systems have been rationalized with the answer: 'while the method is a second best, it is the best we currently have.' In light of the equally well-developed and widely utilized alternatives available, this resistance to improve assessment processes should not be accepted by policy makers. Health technology assessment bodies should consider and, with appropriate modifications, adopt these alternatives as they have the potential to result in more comprehensive, systematic, and accountable decision-making.

Evaluating discrete choice experiment willingness to pay [DCE-WTP] analysis and relative social willingness to pay [RS-WTP] analysis in a health technology assessment of a treatment for an ultra-rare childhood disease [CLN2].

BACKGROUND: Conventional cost-effectiveness analysis [CEA] using cost per QALY thresholds may counteract other incentives introduced to foster development of treatments for rare and ultra-rare diseases. Therefore, alternative economic evaluation methods were explored, namely Discrete Choice Experiment Willingness to Pay (DCE-WTP) and Relative Social Willingness to Pay (RS-WTP), to value interventions for an ultra-rare childhood disease, Neuronal Ceroid Lipofuscinosis type 2 (CLN2). RESEARCH DESIGN AND METHODS: Treatment for CLN2 was valued from a citizen's ('social') perspective using DCE-WTP and RS-WTP in a survey of 4,009 United Kingdom [UK] adults. Three attributes (initial quality of life, treatment effect, and life expectancy) were used in both analyses. For DCE-WTP, a cost attribute (marginal income tax increase) was also included. Optimal econometric models were identified. RESULTS: DCE-WTP indicated that UK adults are willing to pay incremental increases through taxation for improvements in CLN2 attributes. RS-WTP identified a willingness to allocate >40% of a pre-assigned healthcare budget to prevent child mortality and approximately 15% for improved health status. CONCLUSIONS: Both techniques illustrate substantive social WTP for CLN2 interventions, despite the small number of children benefitting. This highlights a gap between UK citizens' willingness to spend on rare disease interventions and current funding policies.

New oral anti-coagulants versus vitamin K antagonists in high thromboembolic risk patients.

BACKGROUND: Oral anticoagulant therapy (VKA) is nowadays the mainstay of treatment in primary and secondary stroke prevention in patients with atrial fibrillation. Given the limited risk-benefit ratio of vitamin K antagonists, pharmacological research has been directed towards the development of products that could overcome these limits, new oral anticoagulants were recently introduced: dabigatran, rivaroxaban, apixaban, and edoxaban. AIM: Scope of the present study was to examine patterns of use, effectiveness, safety and mean annual cost per patient of anticoagulant treatment for non-valvular AF in real clinical practice. METHODS: A retrospective observational cohort study, by using administrative databases (drugs, hospitalizations, clinical visits, lab tests, population registry), was conducted in the Local Health Unit (LHU) of Treviso, Italy, from January 1, 2012 to December 31, 2016. RESULTS: 5597 subjects were selected, 2171 of which satisfied all inclusion criteria. In particular 1355 patients were treated with VKA, 577 patients were treated with NOAC, and 239 patients were treated initially with VKA and subsequently switched to NOAC (switch group). NOAC treatment showed to be superior to VKA and this superiority was statistically significant on both end-points: patients in the NOAC group reported less cardiovascular events (9,9%) and less bleeding episodes (5,5%) versus VKA patients (14,6% and 11,4%; p<,0001 and p = 0,0049, respectively). The mean cost per patient per year was respectively € 1323,9 for patients treated with NOAC versus € 1003,3 for patients treated with VKA. Cost difference appears to be largely driven by drug cost (€ 767,9 for NOAC versus € 17,7 for VKA patients) and by specialist visits and laboratory tests (€ 318,4 for NOAC versus € 733,4 for VKA patients). CONCLUSION: In this retrospective real-world study treatment with NOAC showed to be associated with significant reductions of CV events and bleeding events compared to VKA use, albeit at a higher NHS' direct cost per patient/year, mainly due to higher drug therapy cost.
