Digital Health Literacy Enhancement Strategies Across Diverse Groups: A Scoping Review

Abstract Background The COVID-19 pandemic has accelerated the use of digital health technologies. Digital health literacy (DHL) is essential for effectively understanding and applying electronic health information. However, unequal access and use of these technologies require interventions to improve DHL for fair healthcare access. Objectives This scoping review aimed to identify strategies to enhance DHL in patients and the general population. Methods The review used the Joanna Briggs Institute Scoping Review Methodology and PRISMA-ScR guidelines. Eligibility criteria included a wide population, interventions aimed at improving DHL, with no restrictions on outcomes. The search strategy included electronic databases (MEDLINE, PsycINFO, Web of Science), and AI-based software, AS Review, was used for screening. Results The review found 5149 articles, 44 met the eligibility criteria. Studies focused on different demographic groups and health conditions. Most interventions were in North America and Europe. The study designs varied. Interventions via mobile apps, online platforms, and in-person sessions aimed at various conditions yielded positive results, including increases in DHL, self-management skills, and health-related behaviors. These interventions involved either independent interventions that focused on DHL or integrated interventions that were part of another intervention that aimed at a health outcome and had an element of DHL enhancement. Conclusions The review highlights the importance of DHL in informed decision-making and navigating digital health environments. While many interventions had positive outcomes, methodological limitations challenge the findings, emphasizing the need for more rigorous study designs. Future research should address sustainability, scalability, and the impact of DHL on health disparities, considering cultural sensitivity when developing interventions. Key messages • Scoping review identifies strategies to enhance Digital Health Literacy (DHL), crucial for effective use of health technology. • Despite positive outcomes, methodological limitations exist. Future research should focus on sustainability and scalability.
