These tools have been shown to improve self-management and adherence to medical advice. However, for DHT to be fully effective, patients with chronic conditions must be digitally literate. The eHealth Literacy Scale (eHEALS), an 8\u2011item tool with scores ranging from 8 to 40, was developed to assess individuals\u2019 perceived ability to find, evaluate, and apply digital health information. Assessing patients\u2019 digital health literacy (DHL) and understanding the factors influencing it are essential for improving the accessibility and usability of health resources.<\/jats:p>\n <\/jats:sec>\n \n \n Objective<\/jats:bold>\n <\/jats:title>\n This study aimed to assess DHL in patients with diabetes mellitus (DM), hypertension, and rheumatoid arthritis (RA) through a systematic review and meta\u2011analysis using eHEALS. We sought to determine average DHL scores, examine demographic and socioeconomic factors influencing DHL, and explore its impact on disease management to inform future strategies for enhancing DHL and improving chronic disease outcomes.<\/jats:p>\n <\/jats:sec>\n \n \n Methods<\/jats:bold>\n <\/jats:title>\n Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we conducted a systematic review across 7 databases (PubMed, SCOPUS, Embase, ERIC, CINAHL, Library Literature and Information Science Index, and Google Scholar) from inception to August 14, 2022, with an updated search in October 2024. Eligible studies included adults (\u226518 years) with DM, hypertension, or RA who reported DHL data using eHEALS (8-40) and were original research published in English. Exclusion criteria included studies involving participants younger than 18 years, reviews, meta\u2011analyses, studies not addressing the target diseases, or non\u2011English publications. Study quality was evaluated using the Newcastle\u2011Ottawa Scale (NOS).<\/jats:p>\n <\/jats:sec>\n \n \n Results<\/jats:bold>\n <\/jats:title>\n Eight studies involving 2527 participants were included. The pooled mean eHEALS score was 27.03 (95% CI 25.08-28.98), indicating high overall DHL. Stratified by disease, scores were higher for DM (27.79) and hypertension (28.48) but lower for RA (24.74). Quality assessment indicated a high standard of included studies. Factors influencing DHL included age, education, employment, and perception of the internet as a health resource. Due to the limited number of studies, meta\u2011regression analysis could not be performed.<\/jats:p>\n <\/jats:sec>\n \n \n Conclusions<\/jats:bold>\n <\/jats:title>\n DHL is critical for individuals with chronic conditions, empowering them to make informed decisions and manage their health effectively. However, the scarcity of studies limits comprehensive analysis of DHL determinants. While the internet offers abundant health information, unequal DHL and health skills remain barriers. More inclusive research is needed to fully understand DHL\u2019s impact on health outcomes and mitigate disparities, ensuring equitable access to digital health resources and improving disease management.<\/jats:p>\n
