Learning Through Listening: A Scoping Review of Podcast Use in Medical Education

Purpose To improve understanding of podcast use in medical education by examining current research on descriptive attributes and educational outcomes, highlighting implications of the current evidence base for educational practices, and identifying research gaps to guide future investigation. Method The authors conducted a scoping review, searching PubMed and Embase databases in June-July 2020 for English-language studies of audio-only medical education podcast use in undergraduate, graduate, and continuing medical education. The authors excluded studies without original data or with nonphysician data that could not be separated from physician data. From included studies, the authors extracted data regarding descriptive outcomes (e.g., podcast use, content areas, structure) and educational outcomes (classified using Kirkpatrick's 4 levels of evaluation). Results Of 491 unique articles, 62 met inclusion criteria. Descriptive outcomes were reported in 44 studies. Analysis of these studies revealed podcast use has increased over time, podcasts are a top resource for resident education, and podcasts are being incorporated into formal medical curricula. Educational outcomes were reported in 38 studies. The 29 studies that assessed learner reaction and attitudes to podcasts (Kirkpatrick level 1) showed learners value podcasts for their portability, efficiency, and combined educational and entertainment value. The 10 studies that assessed knowledge retention (Kirkpatrick level 2) showed podcasts to be noninferior to traditional teaching methods. The 11 studies that assessed behavior change (Kirkpatrick level 3) showed improved documentation skills in medical students and self-reported practice change in residents and practicing physicians after listening to podcasts. None of the studies reported system change or patient outcomes (Kirkpatrick level 4). Conclusions Future research should focus on the optimal structure of podcasts for learning, higher-level outcomes of podcasts, and the implementation of podcasts into formal curricula. Podcasts may prove to be essential tools for disseminating and implementing the most current, evidence-based practices.
