Accuracy and Quality of Educational Videos for Elbow Physical Examination: A Search from the Earliest Year until October 2018.

BACKGROUND

Medical students and residents rely increasingly on web-based education. Online videos provide unique opportunities to share knowledge. The objective of this study was to investigate the accuracy and quality of instructional videos on the physical examination of the elbow and identify factors influencing educational usefulness.

METHODS

On October 7, 2018, a search on YouTube, VuMedi, Orthobullets, and G9MD was performed. Videos were rated for accuracy and quality by two independent authors using a modified version of a validated scoring system for the nervous and cardiopulmonary system. Inter-rater reliability was analysed.

RESULTS

The 126 included videos were uploaded between June 2007 and February 2018. Twenty-three videos were indicated as useful for educational purposes. Accuracy, quality and overall scores were significantly higher for videos from specialized platforms (VuMedi, Orthobullets, G6MD) compared to YouTube. Video accuracy and quality varied widely and were not correlated. Number of days online, views, and likes showed no or weak correlation with accuracy and quality. For the overall score, our assessment tool showed excellent inter-rater reliability.

CONCLUSION

There is considerable variation in accuracy and quality of currently available online videos on the physical examination of the elbow. We identified 23 educationally useful videos and provided an assessment method for the quality of educational videos. In educational settings, this method may help students to assess video reliability and aid educators in the development of high-quality instructional online content.
