Evaluation of YouTube Video Content About Developmental Dysplasia of the Hip

Objective The purpose of this study is to investigate the quality and reliability of YouTube videos regarding developmental dysplasia of the hip (DDH). Background YouTube is one of the most popular websites used as a source of information, but the variety in authorship and lack of a peer-review process are problems. Methods The search string "developmental dysplasia of the hip" was inputted to the YouTube search engine, and the first 52 videos returned as a response were assessed. The Video Power Index (VPI) (like ratio*view ratio/100) was used to assess the popularity of the videos. Global Quality Score (GQS) and DDH scores (DDHS) were used to evaluate the quality and educational quality of the videos, and the Journal of the American Medical Association Score (JAMAS) was used to evaluate the accuracy of the source of information. Results According to our research, the mean duration time of the videos was 526 seconds (SD: 813), and the average view count of the videos was 34,644. The mean time since upload was 1,907 days (SD: 1,137). On average, the videos received 10.9 comments, 210.3 likes, and 6.8 dislikes. The mean like ratio and VPI were 92.9 (SD: 19.57) and 25.8 (SD: 53.43), respectively. The mean JAMAS, GQS, and DDHS of all videos evaluated were 1.37 (SD: 0.7), 2.46 (SD: 1.09), and 4.63 (SD: 5.00), respectively. The DDHS and GQS were positively correlated (p: 0.001; r: 65.8%). The GQS and the DDHS were higher in the academic group than in the commercial group (p: 0.01 and p: 0.037, respectively). Conclusions The videos regarding DDH on YouTube generally had poor quality. As a result, to maintain an optimal parent-physician or patient-physician relationship, we suggest that international health societies make their own educational videos for parents, patients, and fellow physicians. Level of evidence Level 3.
