Kyphosis-Related Information On The Internet Is the Quality, Content and Readability Sufficient for the Patients?

A quality-control Internet-based study using recognized quality scoring systems.

The aim of the study is to evaluate the quality, content and readability of online information on kyphosis.

The 3 most frequently used search engines were identified and a search for "Kyphosis" was made in each. The 2 reviewers categorized their Web-sites by type, and the quality of each was assessed using well-known scoring systems, including the DISCERN score, JAMA benchmark, GQS, and the kyphosis specific content score. The Flesch-Kincaid grade level (FKGL) was used to assess the readability. The quality of the information was also evaluated according to the presence and absence of the HONcode.

Sixty unique Web sites were identified and analyzed. The distribution of the categories was 33 (55%) medical, 22 (36.7%) academic, 2 (3.3%) non-physician, 2 (3.3%) commercial and 1 (1.7%) physician. There wasn't statistically significant difference between the sources in terms of DISCERN, JAMA, GQS and KSC scores (P > 0.05). However, a review of the FKGL scores revealed that the academic-based websites' FKGL score was significantly higher than the medical-based websites (P: 0.007). Also there wasn't statistically significant difference among the DISCERN, JAMA, GQS, KSC, FKRS and FKGL scores of the web-sites according to the HON code's presence (P > 0.05).

Information about kyphosis on the Internet is of limited quality and low information value. The readability of the online information in our results showed a significantly higher reading level than the sixth grade level recommended by the AMA and NIH.
