Does the dissemination of comparative data on physician fees affect consumer use of services?

The purpose of this study is to empirically examine the effect of disseminating physician-fee information on consumer behavior. Using an experimental design, the effect of access to physician-fee information on rates of doctor-office visits, expenditures for ambulatory care, and costs per visit are examined. The study includes two research samples: a random sample of 658 state government employees and a random sample of 717 Medicare Part B enrollees. Respondents in each sample were randomly assigned to experimental and control groups, with members of the experimental groups receiving a directory listing the fees charged by local physicians for common procedures. Longitudinal archival and survey data are used in the analysis. Findings reveal that the dissemination of fee data does not yield significant reductions in utilization or expenditures. Policy and research implications are discussed.
