YOUTUBE VIDEOS QUALITY AS EDUCATIONAL SOURCES OF INFORMATION ABOUT EXERCISES AFTER BREAST CANCER SURGERY: Observational Study
ABSTRACT
Background:
Breast cancer (BC) is the most common cancer in women. The prolonged immobilization recommended after surgery morbidity causes in breast cancer survivors. Patients search for detailed information in internet, especially in social networks, about recommended treatments.
Objective:
The aim of this study was to assess the availability, characteristics and accuracy of online health information in Youtube related with BC exercises after surgery, that is accessible for any patient.
Methods:
A systematic search was carried out on uploaded videos in Youtube. Videos´ popularity was evaluated using the Video Power Index (VPI). The informational quality and accuracy of the source of information were measured using the Discern Scale and the Global Quality Score (GQS). Interobserver agreement and individual correlations of each video data were statistically analyzed.
Results:
The first 150 videos were selected and analyzed. The means were 53,963 (Standard deviation -SD- 67,376) for Views, 9:42 minutes (SD 9:15) for Video Length, 2,158 (SD 922) for Days Online, 27.14 (SD 30.24) for Views Ratio, 245 (SD 320.5) for Likes, 13.4 (SD 14.2) for Dislikes and 93.48 (SD 5.42) for VPI. DISCERN scored a mean of 50.97 (SD 19.19; median 53.0 -minimum 25.5; maximum 68.0-); HONcode scored a mean of 78.30 (SD 11.02; median 82.0 -minimum 56.0; maximum 93.5-) and GQS scored a mean of 3.49 (SD 0.74; median 3.5 -minimum 1.5; maximum 5.0-).
Conclusions:
The quality of YouTube videos containing recommended exercises for women after BC surgery, according to Discern and GQS scores, is high. Videos produced by Academic Institutions have the highest educational quality but the lowest levels of popularity. Videos remarkably rewarded by users with their interactions are those produced by Health Institutions and Non-Governmental Organization (NGOs).
