Over the past decade interest in the economic evaluation of health care interventions has risen.1 Reviews of published studies have, however, shown gaps in the quality of work.2 3 4 5 As far back as 1974 Williams listed the essential elements of economic evaluations,6 and more recently Drummond and colleagues set out the methodological areas generally agreed among economists.7 Guidelines for economic evaluations have been promulgated and reviewed by many bodies,8 9 10 11 12 13 14 but few medical journals have explicit guidelines for peer review of economic evaluations or consistently use economist reviewers for economic papers even though they are a major publication outlet for economic evaluations.15 16 17 In January 1995 the BMJ set up a working party on economic evaluation to improve the quality of submitted and published economic articles.
