Similarities of a general medicine clinic in a teaching hospital to internal medicine practice. Clinic compared with private practice.

The authors undertook this study to determine whether a general medicine clinic in a teaching hospital provided an experience similar in content to that in the office of a general internist. Data on all patient visits to the university clinic during 1979 were collected. Analyses of 4856 visits revealed significant differences (p less than 0.001) in duration of visit, admission rate, and referral rates between the clinic and internists studied by the National Ambulatory Medical Care Survey (NAMCS). However, the 12 most common problems seen in the clinic were among the 15 most common problems seen by NAMCS physicians despite some differences in the prevalence of certain diagnoses. Knowing the relative prevalence of specific diagnoses in this setting helps teach cost--benefit principles of ordering diagnostic studies designed to detect uncommon problems. This study supports the value of a teaching hospital ambulatory care experience as preparation for the practice of general internal medicine.
