How podcasts teach: A comprehensive analysis of the didactic methods of the top hundred medical podcasts.

Medical podcasts have grown in popularity, but little is known about their didactic methods. This study sought to systemically describe the pedagogical approach employed by the 100 most popular medical podcasts in the United States. This study also aimed to assess factors related to quality control and conflicts of interest in podcasting. The authors averaged the rank positions for Apple podcasts in the Medicine category in the United States from 06/01/18 to 09/30/20 to generate a list of the 100 highest-ranked medical podcasts. They developed and validated a categorization system of didactic methods based on Bloom's taxonomy and collected data on didactic methods, as well as podcast affiliation, target audience, format, advertising, continuing medical education (CME) offerings, and presence of a reference list or review process. Of the 100 most popular medical podcasts, 91 are educational.

Compared with podcasts intended for other audiences, PIPEs engage higher levels of Bloom's taxonomy ( Medical podcasts employ a variety of didactic methods, including those ranked highly on Bloom's taxonomy. Unlike traditional medical education, PIPEs are commonly produced by individuals or companies and targeted to all levels of medical learners.
