John Brazier is Professor of Health Economics at the Health Economics and Decision Science section of the School of Health and Related Research at the University of Sheffield. He has more than 20 years’ experience of conducting economic evaluations of health care interventions for policy makers. He has also undertaken numerous economic evaluations alongside clinical trials and decision analytic models. He has a particular interest in the measurement and valuation of health for economic evaluation where he has published widely. He is perhaps best known for his work in developing a preference-based measure of health for the SF-36, but more recently has extended these methods to a number of specific condition including measures in asthma, cancer, overactive bladder, dementia and epilepsy. More recently he has been developing ways to incorporate equity concerns such as burden of disease into the weights applied to QALYs for Value Based Pricing. He is Director of an Economic Evaluation Policy Research Unit (EEPRU) that is funded by the Department of Health in England. He was a member of the National Institute for Clinical Excellence (NICE) Technology Appraisal Committee from 2000-2004 and is a member of the Working Group on revising Methods of Economic Evaluation for Technology Appraisal in 2012.
