Quality and Reliability of Publicly Accessible Information on Laser Treatments for Urinary Incontinence: What Is Available to Our Patients?

Abstract

Study objective: To determine the quality and reliability of the top 20 internet search results for laser treatment of stress urinary incontinence (SUI).

Design: Review of 20 websites.

Setting: N/A.

Patients: None.

Interventions: An internet search with the most popular search engine, Google, was undertaken to identify the top 20 websites for laser treatment of SUI. The DISCERN instrument, Journal of the American Medical Association (JAMA) benchmarks, and Health on the Net Foundation Code of Conduct certification, which are standardized, validated tools for the analysis of website quality, credibility, and transparency, were used independently by 7 healthcare workers. The readability of the information was assessed by a single reviewer using the Flesch-Kincaid Grade Level and Automated Readability Index. The intraclass correlation coefficient was calculated to document the reliability among website assessors.

Measurements and main results: Of the 20 websites reviewed, 15 were created by private clinics, 2 by online newspaper or newsletter sites, and 3 by laser medical device manufacturers. None of the websites met all of the JAMA criteria: 1 had attained authorship, 1 had clear attribution, none had adequate disclosure, and 2 achieved currency. None of the websites took part in the Health on the Net Foundation Code of Conduct certification program. The mean DISCERN score (to determine the quality of websites) was 40 (out of 80), with the lowest average scores within the DISCERN tool primarily associated with clarity around sources of information, website bias, posting dates, risks of treatment, and shared treatment decision-making. The intraclass correlation coefficient was calculated for the DISCERN tool (0.72; 95% confidence interval, 0.48-0.87) and JAMA benchmarks (0.85; 95% confidence interval, 0.73-0.93). The mean Flesch-Kincaid Grade Level was 13.2 (±3.1) and the Automated Readability Index scores ranged from 7.6 to 22.8 (mean 13.5 ± 3.5).

Conclusion: There is a lack of good quality, reliable, and unbiased information available to patients on laser treatment of SUI on the most commonly searched websites. Information is presented at a reading level that is above that of the average reader, which may indicate that patients will have trouble comprehending the information.
