Impact of Ambulatory Blocks on Pulmonary Critical Care Fellow Outpatient Training Experience

The Accreditation Council for Graduate Medical Education requires Pulmonary and Critical Care Medicine (PCCM) fellows spend a minimum of 7% of their time in the outpatient setting over 3 years of training. In a multi-institutional survey, only 47% of PCCM fellows rated their ambulatory training as adequate. Internal medicine residencies previously adopted the "x + y" scheduling model, which separates inpatient ("x") and outpatient ("y") rotations to provide focused ambulatory experiences, to address similar concerns.

To observe the effects of dedicated ambulatory blocks at a single academic PCCM fellowship on fellow exposure to outpatient pulmonary medicine, and on fellow and faculty perceptions of education.

In the 2021-2022 academic year, PCCM fellows of all class years in a single academic fellowship program in the northeast United States rotated through four 2-week ambulatory blocks that included longitudinal clinics, themed subspecialty clinics, and a dedicated educational half-day for small group learning. Before the intervention, fellow ambulatory clinics were scheduled longitudinally one-half day per week during inpatient and research blocks. Both fellows and faculty were surveyed before and after the intervention; fellows were also interviewed via focus groups at the conclusion of the intervention. The degree of subspecialty clinic exposure was compared before and after intervention.

There was an increase in the quantity and variety of pulmonary subspecialty clinics per fellow when compared with preintervention years (P < 0.01). After intervention, we observed increased fellow satisfaction with ambulatory education, perceived preparedness for independent practice, and satisfaction with subspecialty clinic exposure (P < 0.05). Faculty satisfaction with fellow ambulatory pulmonary education also increased (P < 0.05). Thematic analysis from focus groups highlighted focused topical learning, exposure to the breadth of pulmonary medicine, career development, interaction with engaged faculty experts, and enhanced interprofessional competence.

The ambulatory block structure provides a potential model to expand PCCM fellow outpatient pulmonary training through increased exposure to ambulatory pulmonology and dedicated ambulatory teaching. Important features of the ambulatory block structure include separation of outpatient clinics from competing responsibilities, expansion of fellow pulmonary exposure, opportunities for deliberate practice, and faculty engagement in fellow education.
