RELIABILITY AND QUALITY OF VIDEOS ON CONGENITAL HEART DISEASE ON YOUTUBE BRAZIL

Abstract

Introduction: Congenital heart disease (CHD) is a frequent structural anomaly in the child population, with a significant impact on public health. YouTube, as a widely used platform, offers accessible health content, but the reliability and quality of the information available is often questioned. Objective: To analyze the reliability and quality of videos on congenital heart disease on YouTube Brazil, using validated instruments. Methods: This is a cross-sectional study based on the analysis of 61 informative videos on CHD, published between August and October 2024. The search was performed on YouTube using the term "congenital heart disease", applying filters for standardization and excluding videos without thematic relevance. The evaluation was performed by two independent examiners using the modified DISCERN checklist and the Global Quality Score (GQS) scale. The data were analyzed by descriptive statistics, and inter-rater reliability was evaluated by the intraclass correlation coefficient (ICC). Results: The median view of the analyzed videos was 16,960, while the median duration was 8 minutes. Most of the videos (88.5%) were produced by health professionals, with a predominance of the class or lecture format (54.1%). The reliability of the information, assessed by the DISCERN checklist, had a median of 2.29, indicating moderate quality. Analysis by GQS revealed that 58.2% of videos were rated as good quality, while only 12.3% reached a level of excellence. Conclusion: The videos about CHD on YouTube Brazil have satisfactory overall quality, but with limitations in terms of scientific reliability. It is necessary to encourage the production of more robust, evidence-based content to improve health education and combat misinformation on digital platforms.
