Internal Medicine Acting Internship Trends in Rotation Structure and Student Responsibilities: Results from a 2023...

The acting internship (AI) in internal medicine plays a key role in the transition from medical school to residency. While there have been recent changes in medical education including a pass/fail USMLE Step 1 and increasing use of competency-based assessment, there has not been a large survey of the state of the AI in many years.

To assess the current landscape of the internal medicine AI and identify areas in need of standardization.

This was a voluntary online survey of medical schools in the United States (U.S.).

Course directors of the AI rotation at U.S. medical schools.

Number of AI rotations required for graduation, length of AI rotation, types of services allowed for AI, clinical responsibilities of students, curricular components.

Response rate was 50.7% (71/140 LCME accredited schools). All responding institutions require at least one AI for graduation, with nearly all schools integrating students into resident teaching teams, and almost half also allowing AI students to work on hospitalist services. Students carry 3-4 patients per day on average with a maximum of 5-6 in most institutions. Students are responsible for most aspects of patient care including notes, orders, interprofessional communication, and transitions of care. Night call or night float responsibilities are infrequently required. The structured curriculum published by AAIM is used by only 41% of schools.

The internal medicine AI continues to be a staple in the medical school experience, but there is variation in the structure, curriculum, and expectations on the rotation. Opportunities exist to improve standardization of the AI experience and expectations to better prepare medical students for the transition from medical school to residency.
