ABSTRACT
OBJECTIVES: This study aims to conduct a systematic literature review (SLR) to summarise associations between health literacy and inflammatory arthritis (IA) outcomes, to inform management.
METHODS: Inclusion criteria were adults with IA; studies assessing health literacy or interventions targeting health literacy; observational and qualitative studies, randomised controlled trials. Searches were performed using MeSH headings for health literacy and IA. Data were extracted on demographics, health literacy assessment and relevant outcomes, grouped into themes using vote-counting.
RESULTS: Of 3087 identified articles, 29 were included. The total number of participants across all studies was 16,402, comprising mostly females, with a mean age of 46 to 70 years. Ethnicity was reported in 13 studies; most participants were Caucasian. The most frequently reported IA was rheumatoid arthritis. Health literacy measures included: Test of Functional Health Literacy in Adults (n = 13); Single Item Literacy Screener (n = 10); Rapid Estimate of Adult Literacy in Medicine (n = 6); Health Literacy Questionnaire (n = 2). Six main associations were identified with low health literacy: higher disease activity; more disability; more mental health symptoms (including depression and anxiety); higher healthcare use; lower medication adherence; lower use of internet, telehealth and technology.
CONCLUSIONS: In people with IA, low health literacy is generally associated with worse outcomes including higher disease activity, mental health symptoms and disability, higher healthcare use, lower medication adherence, and lower use of technology. This is the first SLR to synthesise associations between health literacy and outcomes in IA. Our findings should inform policy and resource allocation and improve the quality of care for patients with IA and low health literacy.
