Understanding the clinical appropriateness of a procedures use may be critical in explaining geographic variations in its use. Little is known, however, about whether data on appropriateness can be obtained from a medical record. A national panel of physicians formulated a list of 300 mutually exclusive, detailed clinical indications for performing coronary angiography. Using this list, we compared the reasons physicians perform coronary angiography as revealed in medical records with those given in interviews with the physicians who actually did the procedure. Thirty-five of 47 eligible billing entities 74 from two Los Angeles Professional Standards Review Organization areas participated. These physicians practiced in 14 hospitals and accounted for 81 of all angiographies performed on Medicare patients in the two areas. Sixty- six records approximately two per physician were reviewed physician interviews were conducted by two trained data collectors who were blinded to each others results.
