While prior studies have explored staffing infrastructure for primary care practices in general, little is known about the range of academic primary care practice models and supports available for academic general internists. To characterize the range of practice arrangements and expectations for attending academic physicians in general internal medicine (GIM) practices at the top 22 medical schools across the USA. Cross-sectional survey administered electronically between October 30, 2022, and December 28, 2022. Clinical leaders in GIM at the top 22 primary care medical schools, as identified by the 2023 US News and World Report Rankings. Clinical load, productivity expectations, cross-coverage, and team-based care models. Twenty-two leaders responded, representing 68% (15/22) of medical schools surveyed. The practices were mostly in urban locations (18/22, 82%) and 86% (19/22) included residents. Practices ranged from 7 to 200 PCPs and from 3 to 112 clinical FTEs. A full-time (1.0 FTE) clinical role for academic attending GIM physicians entailed a median of 9 (IQR 8, 10) weekly half-day clinic sessions, with a median panel size expectation of 1600 (IQR 1450, 1850) patients and a median yearly RVU expectation of 5200 (IQR 4161, 5891) yearly RVUs generated. Staff support was most commonly present for prescription refills and patient portal message checks. It was less commonly available for time sensitive form completion. Occasional clinical coverage for other physicians was an expectation at all practices. In this study, we characterize the organization of and supports available in academic GIM practices affiliated with the top primary care medical schools. Our findings provide comparative information for leaders of academic GIM practices seeking to enhance primary care delivery for their faculty and trainees. They also highlight areas where standardization may be beneficial across academic GIM.
