Abstract
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.
