Evaluating the educational quality of seasonal influenza videos on YouTube

American College of Chest Physicians

TORONTO (October 23, 2017)--According to Pew Research center, in 2013, about six out of ten Americans searched for health information online in the past year. With patients regularly turning to the internet for health advice, a group of researchers aimed to evaluate the educational quality of seasonal influenza videos on the user-generated, video-sharing platform, YouTube.

Researchers conducted akeyword search of "seasonal influenza" from January 28 to February 5, 2017. The top most viewed videos that appeared in the search results were included and analyzed for video characteristics, source, and content. The source of videos was then classified as health-care provider, alternative-medicine provider, patient and/or patients' parents, company, media, or professional society. Utilizing the latest CDC guidelines, a scoring system was created to evaluate the quality (-10 to +40). Negative points were provided for misleading information. Ten blinded reviewers scored each video independently.

Three hundred videos were analyzed, with a median of 341 views, 1 likes, 0 dislikes, and 0 comments. More video presenters were male (39.3%) and the predominant race depicted was Caucasian (73.6%). The most common type of video source was professional societies (38.3%) and least represented was alternative medicine provider (1.3%). Among the six video sources, the mean scores showed a statistically significant difference from each other (p<0.001). There was a higher mean score for health-care provider (4.50) when compared with other video sources (mean scores ranging from 0.47 to 4.17).

"This study confirmed that most YouTube videos on seasonal influenza are provided by professional societies and health-care providers, with over half of the videos attempting to educate patients," says Dr. Lakshmi Kallur, lead researcher and resident physician in the Department of Internal Medicine at East Tennessee State University's Quillen College of Medicine, "these videos, although containing accurate information, did not fulfill our criteria as far as educating patients thoroughly."

Further results from this study will be shared at CHEST Annual Meeting 2017 in Toronto on Wednesday, November 1, 1:30 PM-2:30 PM at the Metro Toronto Convention Centre. The study abstract can be viewed on the journal CHEST® website.
