The Capability Approach initiated by Nobel Prize winning economist, Amartya Sen has inspired the development of a number of outcome measures of patient benefit for use in health economic evaluations. Capability measures are becoming increasingly recognised as useful measures in health economics and some measures are now considered by NICE to inform treatment decisions. In this talk, Paul Mitchell will give an overview of the current capability measures available and provide some suggestions on how to use these measures in economic evaluation, with particular emphasis given to the ICECAP capability measures. He will also discuss some preliminary findings from his ongoing research involving a think aloud study, which aims to explore face validity, feasibility of completion and acceptability of the EQ-5D-5L, ICECAP-A and ICECAPO measures in renal patients and to determine which ICECAP measure is more appropriate for this patient group. Finally, he will highlight further developments in the use of capability measures in health economics and future directions for research.
