Evaluating the accuracy and reliability of overactive bladder-related YouTube videos: A digital health quality analysis using DISCERN and GQS tools.

BACKGROUND

Overactive bladder (OAB) is a prevalent condition, and patients increasingly turn to online platforms such as YouTube for information, raising concerns about accuracy and reliability.

PURPOSE: This study aimed to evaluate the quality and reliability of YouTube videos related to overactive bladder (OAB) using two validated instruments: the DISCERN tool and the Global Quality Scale (GQS).

METHODS

A systematic and structured YouTube search strategy, adapted from systematic review methodology but tailored for digital platforms, was conducted using the keyword overactive bladder. The first 100 videos retrieved were screened, and 60 met the inclusion criteria: English language, duration of at least 60 s, and relevant educational content. Exclusion criteria included non-English language, duplicates, advertisements, and purely promotional material. Two independent urologists evaluated each video using the DISCERN tool (range: 16-80) and GQS (range: 1-5). Additional data collected included video length, view count, uploader type, and thematic content. Descriptive statistics and correlation analyses were performed.

RESULTS

The median video duration was 5.6 min (IQR: 3.4-8.2), with a median view count of 34,200 (IQR: 12,500-89,000). The mean DISCERN and GQS scores were 45.2 ± 10.1 and 2.9 ± 0.8, respectively, indicating moderate overall quality. Videos uploaded by healthcare professionals or institutions had significantly higher DISCERN and GQS scores compared to those uploaded by individuals or commercial entities (p < 0.001). Only 28% of videos addressed neurogenic causes of OAB, and 41% did not mention behavioral therapy. A weak but statistically significant positive correlation was observed between GQS score and view count (ρ = 0.34, p = 0.01).

CONCLUSIONS

YouTube contains a wide array of OAB-related videos, but their quality and reliability vary considerably. While some content is accurate and informative, significant gaps remain, particularly regarding neurogenic etiologies and behavioral management. Healthcare professionals should guide patients toward trustworthy resources and consider producing evidence-based content to improve digital health literacy.
