An evaluation of the readability, quality, and accuracy of online health information regarding the treatment of hypospadias.

BACKGROUND

Hypospadias is one of the most common genital anomalies. Treatment of hypospadias requires surgical repair, usually in childhood. Patients are increasingly using the internet to learn more about their health or that of their children, which can often empower patients to make well-informed healthcare decisions.

OBJECTIVE

The objective of this study was to evaluate not only the readability but also the quality and accuracy of available online health information for the treatment of hypospadias.

STUDY DESIGN

Search terms for hypospadias treatment were queried on major search engines. Each website was classified into one of four categories: institutional, commercial, charitable organization, or personal website. Content on each website discussing treatment options was analyzed for readability using three readability formulas. A validated tool, the DISCERN instrument, was used to measure the quality of online health information regarding hypospadias treatment. Accuracy was independently assessed by two pediatric urologists on a 1-5 scale, in which 1 and 5 correspond to 0% and 100% of the information in the text being accurate, respectively.

RESULTS

A total of 150 search engine results were acquired, of which 46 were analyzed for readability, quality, and accuracy. The mean readability scores across all websites were 14.89 (Gunning-Fog), 11.01 Simple Measure of Goddledygook (SMOG), and 8.44 (Dale-Chall), which correspond to an 11th- to 12th-grade reading level. Most websites (65.2%) were considered of 'good' quality. Readability and quality scores were not statistically different between website categories. Institutional and charitable websites had the highest mean accuracy scores (3.91 and 3.50, respectively), with institutional websites proving to have significantly more accurate information regarding hypospadias treatment than commercial websites (3.91 and 3.42, respectively; P = 0.001).

DISCUSSION

Pediatric urologists should know what information about hypospadias and its treatment exists on the Internet and understand if it is accurate and of good quality and, more importantly, if the material is written at a reading level comprehensible by the majority of parents. Limitations included analysis of only English-written websites regarding hypospadias treatment specifically, using search engines alone rather than other online resources, not evaluating online videos or illustrations, and not using more than two pediatric urologists for determining content accuracy.

CONCLUSION

This study demonstrates that online health materials regarding hypospadias and its treatment are written at a level far greater than the reading level of most adults. Most websites were considered of adequate quality, and websites from institutions or references had significantly more accurate information than those from commercial websites.
