Evaluation of Trending YouTube Videos on Heel Prick Test Refusal, Mandatory Newborn Screening, and the “Heel Prick Test Myth”

Aims: This study aims to systematically evaluate the informational quality of the most highly viewed YouTube videos addressing sensitive public health issues with significant societal impact, including heel prick test refusal, mandatory newborn screening programs, and the “heel prick test myth.” Materials and Methods: In this study, videos obtained through YouTube searches using the keywords “heel prick test refusal,” “mandatory newborn screening,” and “heel prick test myth” were analyzed. The reliability of video content was assessed using the modified DISCERN instrument, while overall information quality was evaluated using the Global Quality Scale (GQS). Based on the scores derived from these scales, videos were classified into three categories: good/excellent, moderate, and poor quality. Results: Among the evaluated videos, 51.8% were classified as good/excellent quality, 28.9% as moderate quality, and 19.3% as poor quality. Videos in the good/excellent quality group had significantly higher median DISCERN scores compared with those in the moderate and poor quality groups. No significant correlation was observed between video popularity and GQS or DISCERN scores. However, a strong and statistically significant positive correlation was found between mean GQS and DISCERN scores. In addition, total likes were significantly and positively correlated with both total comments and total views. Conclusion: Many YouTube videos on heel prick test refusal, mandatory newborn screening, and the “heel prick test myth” lack sufficient quality and evidence-based content, while high-quality videos are limited. This highlights the need to strengthen the reliability of digital health information and the visibility of expert-produced content.
