Contributions of Health Literacy for Patient Safety in Primary Care: A Scoping Review

Introduction: This study provides unprecedented scientific evidence for the expansion of health literacy as a tool capable of increasing patient safety through effective communication between health care professionals and their patients, especially in primary health care. Objective: To map the evidence available regarding the impact of health literacy on care safety for adult patients in primary health care. Materials and methods: This is a scoping review in line with the Joanna Briggs Institute method, which covers care, techniques, protocols, or health literacy methods used to improve primary health care. The Medline (PubMed), Web of Science, Scientific Electronic Library Online (SciELO), Virtual Health Library, Scopus, Cinahl, and Google Scholar databases were used for the gray literature search. Original studies available in full and published until January 2023, in all languages covering the topic, were included. Two reviewers screened them by title and abstract, and three reviewers read the full texts and extracted data from the selected articles presented in flowcharts, tables, and descriptive narratives. Results: A total of 3749 studies were found, of which 23 were selected. From these, the following categories emerged: ‘The impact of health literacy on the engagement and health outcomes of primary health care users;’ ‘Interventions that contribute to health literacy in primary health care;’ and ‘Evaluation of users’ and professionals’ perspectives on health literacy.’ Conclusions: Health literacy interventions focused on primary care should be encouraged within health care services to promote care, prevent illnesses, and inspire the population’s transformation process, with a direct impact on patient safety.
