Multiple models of clinical exposure to primary care exist within undergraduate medical education (UME) and graduate medical education (GME). In this narrative review, we explore the evidence behind these different models of exposure, their alignment with positive promoters of primary care careers, and the pros and cons of each. Without positive exposure to primary care during training, sustaining the future primary care work force becomes increasingly challenging. Here, we explore multiple models of clinical exposure in UME, including longitudinal integrated clerkships, primary care tracks, and primary care clerkships. Within GME, we will review the impact of primary care tracks, Area Health Education Centers, block scheduling models, and continuity clinic scheduling models. The goal of this narrative review is to allow educators to think broadly and intentionally about the array of models to develop positive primary care experiences and perceptions in training, ultimately sustaining the primary care workforce.
