A major difficulty within internal medicine is achieving the optimal balance between inpatient and outpatient primary care duties. In recent years, research has proposed variations of the “4+1” model to improve efficiency. In a military treatment facility, resident internal medicine providers spend 4 weeks on inpatient service followed by one week of outpatient primary care clinic. This allows for regular, spaced repetition for the resident’s outpatient primary care experience. We instituted this model for our PGY2 and PGY3 classes this past academic year and explored the impact it made on resident primary care experiences. In a single class of internal medicine residents at a single institution, introduction of the “4+1” ambulatory primary care training model was associated with statistically significant positive changes in perceived primary care ambulatory experiences. Additionally, this schedule maximizes longitudinal patient care and minimizing outpatient primary care duties while on core rotations. With this data, we are planning on expanding this scheduling model to all training years.
