Health Literacy Assessment of NHLBI COPD Education Playlist on YouTube.

The National Heart, Lung, and Blood Institute (NHLBI) Learn About Chronic Obstructive Pulmonary Disease (COPD) YouTube playlist educates the public on diagnosing, treating, and managing COPD. Despite its potential benefits, it is unknown if users with inadequate health literacy will likely understand and apply the information described in these videos. Assess the Learn About COPD playlist's readability, actionability, and understandability. Central tendency statistics were computed to describe the meta-data of 28 videos available as of April 2023. Assessments included the Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT-AV), Accessible Health IT for Limited-Literacy Populations Checklist (LLPC), and the Modified Centers for Disease Control and Prevention (CDC)-Clear Communication Index (CCI) for audiovisual materials. Playlist videos received an average of over 2,000 views (Mdn = 2,220, IQR = 496–8336), with very few "likes" (Mdn = 13, IQR = 1–48 "likes"). PEMAT-understandability (Mdn = 81.81%, IQR = 80–97.72%) and LLPC (Mdn = 87.50%, IQR = 75–93.75%) scores were high (above 80%). However, the modified CDC-CCI median score was 57.14% (IQR = 42.86–75%), and the median PEMAT-actionability score was 50% (IQR = 0–66.67%). The playlist earned passing understandability, acceptability, and usability scores but scored poorly on actionability and communication clarity. Findings could inform enhancements to NHLBI's Learn About COPD YouTube playlist. [ABSTRACT FROM AUTHOR]
