Objectives: To test the hypothesis that it may be possible to reduce the number of tests and laboratory expenditure by periodic peer comparison paper feedback to physicians on statistic data of the number of tests which they prescribed. Methods: A prospective controlled trial was conducted at the outpatient clinics of Changhua Christian Hospital. Physicians from two different departments were selected as intervention group and control group to avoid contamination between groups. Among all the departments in this hospital, patients in the Department of Internal Medicine and the Department of Family Medicine have the most similar disease patterns. Five sex-, age-, and years of practice-matched physicians from each of the two departments were selected. Physicians from the Department of Family Medicine received monthly feedback from January through April in 1999 on their own statistic data of the number of tests per prescription of the preceding month. Physicians from the Department of Internal Medicine received no intervention. Prescriptions of these 10 physicians from January through April in 1998 were used as baseline data. Results: Number of prescriptions during the intervention period was 11,730 for feedback group and 7,263 for control group. During the study period, mean number of tests per prescription decreased in the feedback group (P＜0.0l) and increased in the control group (P＜0.0l)Laboratory expenditure decreased in the feedback group (P＜0.00l), but had no significant change in the control group (P=0.11), Conclusions: Periodic peer comparison paper feedback to physicians on statistic data of the number of tests they prescribed can effectively reduce the number of tests and laboratory expenditure.(Taiwan J Public Health. 2002;21(2):107-114)
