Objectives: Clinical reasoning skills are required for safe care, yet they are not consistently taught to advanced practice providers (APPs). In hospital medicine, where APPs work semi-independently, gaps in clinical reasoning can increase the likelihood of error. To address this, we developed a module that uses diagnostic root cause analysis (RCA) to teach clinical reasoning skills to hospital medicine APP fellows.
Methods: The curriculum was delivered from July 2021 to March 2025. Fellows selected real-world diagnostic errors encountered during clinical rotations, created cognitive fishbone diagrams, and presented their analysis in small-group.
Results: Twenty-seven fellows completed the module and pre-post assessment surveys. Statistically significant improvements were observed across all six domains of knowledge and confidence related to identifying error contributors, analyzing cases, and setting goals. Free-text responses highlighted the module's emotional safety, peer learning value, and normalization of diagnostic reflection. Two learners published their projects as academic posters, and one graduate now co-facilitates the sessions.
Conclusions: This module offers a scalable, time-efficient approach to clinical reasoning education that is adaptable across learner levels and specialties. Its peer-led design fosters psychological safety, reflective practice, and creates a natural pathway for APPs to engage in microscholarship - addressing a critical gap in both education and academic inclusion.
