Patients of internists in hospital outpatient departments and in private practice.

To test the contention that patients in outpatient departments and private practices differ, variables were assessed that might affect both the process and the outcome of medical care. Two groups of 60 patients consulting nine Montreal internists who worked in both private practice and in an outpatient department of a university teaching hospital were surveyed. The internists served as their own controls. The two groups of patients were compared for 57 demographic, socioeconomic, access, utilization, attitudinal and current medical status variables. Financial factors were minimized by the existence of universal health insurance. The outpatient group was found to be older, less fluent in English, less likely to be employed, less educated, less wealthy, more dependent on public transportation, more disabled, more likely to use ambulatory services, more anxious about health, and more sceptical about physicians, yet more dependent on them than the private practice group. The outpatient group tended to have more active, significant medical conditions and to receive more prescriptions for medication than the private practice group, in contrast to the national patterns in the practice of internal medicine in the United States. Medical educators, researchers, administrators and providers of health care who have assumed that these two groups of patients are comparable must re-evaluate their practices.
