Abstract
A key task in evaluating the cost-effectiveness of
medical interventions is to place a value on the health
improvements achieved by patients. Generic instruments are
available to convert a qualitative description of health state into a
utility measure, and this meeting addresses several statistical
issues in the estimation of such utilities.
Keith Abrams' talk is concerned with trials where patients in the
trial have their health state recorded and one of these generic
measures is used to convert to a utility. Problems arise when only
a subset of patients have health state recorded, or when some
attributes of health state are missing for some patients.
Samer Kharroubi looks at the original data from which the utility
function converting health state to utility is derived, and presents a
general technique for estimating this function. A Bayesian model
is used to reflect the belief in smoothness and monotonicity of the
function.
Ben van Hout extends that analysis by considering how to
estimate utility functions for different countries or cultures. It is
recognised that different countries might value health differently, but
estimates from a substantial dataset on one country might provide
prior information, and allow a smaller sample size, when
considering a new country.
