Readability of Online Patient Education Materials for Total Joint Arthroplasty: A Systematic Review

Abstract

BackgroundAs the demand for total joint arthroplasty continues to grow, patients increasingly turn to internet sources for accessible orthopaedic health information. We sought to evaluate the readability of online hip and knee arthroplasty patient education materials (PEMs). MethodsOur systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-P guidelines (PROSPERO registration of the study protocol: CRD42022358872, September 19th, 2022). PubMed, EBSCOhost, Medline, and Google Scholar electronic databases were utilized to identify all studies evaluating online PEMs related to total joint arthroplasty between January 1, 2000, and August 1, 2022. The quality of studies was assessed with the Joanna Briggs Institute scale. ResultsOur initial search yielded 360 publications which were then screened for appropriate studies aligned with our review’s purpose. A total of eleven cross-sectional studies were included. The total sample size across the studies consisted of 662 PEMs. Five studies evaluated professional or academic orthopaedic websites, six evaluated PEMs through web engines, and three evaluated apps or commercial websites. Most included studies found PEMs to be well above the recommended 6th-grade reading level. ConclusionArthroplasty PEMs produced by orthopaaedic websites, web searches, and apps have readability scores well above the recommended levels. Given the importance of health literacy on patient outcomes and satisfaction, work needs to be done to improve the readability of these materials.
