Abstract
Initiation of a hospital-based faculty group practice to replace part of a general medical clinic was evaluated in a quasi-experimental design. Practice setting (where patients received their primary care) was the independent variable. The group practice, unlike the traditional clinic, emphasized primary care by providing 24-hour, seven day/week access by telephone; continuity between inpatient and ambulatory care (all patients admitted as private patients of group practice attending physicians) and coordination of care. Resource use, including visits to the primary care site, the emergency room and specialty clinics, and tests ordered at each site were tracked for one year by chart review. Multivariate analysis showed that, contrary to expectations, group practice patients had no fewer emergency room or specialty clinic visits, although they did make more visits to the practice. With respect to tests, practice patients had almost two more tests ordered in the primary care site than clinic patients, although there was no concomitant reduction in tests ordered at other sites. The authors conclude that ambulatory care resource use is an insufficient measure of the effect of a change in practice setting.
