Credibility, Accuracy, and Comprehensiveness of Internet-Based Information About Low Back Pain: A Systematic Review

Abstract

Background Low back pain (LBP) affects millions of people worldwide, and misconceptions about effective treatment options for this condition are very common. Websites sponsored by organizations recognized as trustworthy by the public, such as government agencies, hospitals, universities, professional associations, health care organizations and consumer organizations are an important source of health information for many people. However, the content of these websites regarding treatment recommendations for LBP has not been fully evaluated. Objective This study aimed to determine the credibility, accuracy, and comprehensiveness of treatment recommendations for LBP in noncommercial, freely accessible websites. Methods We conducted a systematic review of websites from government agencies, hospitals, universities, professional associations, health care organizations and consumer organizations. We conducted searches on Google. Treatment recommendations were coded based on the 2016 National Institute for Health and Care Excellence (NICE) guidelines and the 2017 American College of Physicians guideline on LBP. Primary outcomes were credibility of the website (4-item Journal of the American Medical Association benchmark), accuracy (proportion of website treatment recommendations that were appropriate), and comprehensiveness of website treatment recommendations (proportion of guideline treatment recommendations that were appropriately covered by a website). Results We included 79 websites from 6 English-speaking countries. In terms of credibility, 31% (25/79) of the websites clearly disclosed that they had been updated after the publication of the NICE guidelines. Only 43.28% (487/1125) website treatment recommendations were judged as accurate. Comprehensiveness of treatment recommendations correctly covered by websites was very low across all types of LBP. For acute LBP, an average of 28% (4/14) guideline recommendations were correctly covered by websites. Websites for radicular LBP were the least comprehensive, correctly covering an average of 16% (2.3/14) recommendations. Conclusions Noncommercial freely accessible websites demonstrated low credibility standards, provided mostly inaccurate information, and lacked comprehensiveness across all types of LBP.

YouTube as a Source of eHealth: Is It Beneficial for Lumbar Disc Herniation Exercises?

“…Ferreira et al reported that 43.3% of recommenda-tions about low back pain presented on websites were accurate. 18 Costa et al evaluated websites presenting information about low back pain on three different dates (2010, 2015, and 2018) and reported that poor quality websites increased during this period. 19 In 2018, 86% of websites were of poor quality.…”

“…There are several studies evaluating the quality of information on LDH and low back pain presented on websites. [17][18][19] Additionally, YouTube videos related to various diseases were evaluated in different studies, but there is no published research that investigates YouTube videos on LDH exer-cises. 12,20 Therefore, our purpose in this study was to analyze YouTube videos related to LDH exercises with specific aims to determine the quality of the information in the videos and to define which sources provided high quality health-related information.…”

Musculoskeletal healthcare: Have we over‐egged the pudding?

“…A study of Australian consumer information on knee arthroscopy for symptomatic osteoarthritis found that only 6 of 93 documents cited research and only 8 of 93 advised against the procedure . A study of information on low back pain on 79 “trustworthy” (eg government, university, hospital) websites from six countries found that less than the half the treatment recommendations were accurate . There is also predisposition with regard to health care to believe that more is better and that new is better …”
