Abstract

This thesis develops the implementation of the capability approach within health economic evaluations. Until now, the focus of applying the capability approach within health economics has centred on its theoretical merits, as well as the development of capability questionnaires. The aim of this research is to establish methods for applying the capability approach in an evaluation framework. Specifically, this is done by (i.) investigating how a measure of capability well-being, the ICECAP-O, can be incorporated into a health economic model and (ii.) establishing the objective of capability evaluations to aid the decision-making process in allocating scarce resources for health. The relationship between capability and condition-specific health status for osteoarthritis patients is studied through statistical mapping. Methods from the capability literature are drawn upon to construct a methodology for generating capability outcomes that can be used to aid decision-making. This methodology is then tested on an existing economic model, the Birmingham Rheumatoid Arthritis Model (BRAM). Key findings from this thesis are that (i.) it is feasible to predict capability from a condition-specific health instrument and (ii.) establishing “sufficient capability” as the objective for capability evaluations. Further research is required to see what difference a capability based evaluation would make in practice.
