Nursing Interventions in Primary Health Care to Promote Therapeutic Adherence in Systemic Arterial Hypertension: A Scoping Review

Systemic arterial hypertension (SAH) is a highly prevalent chronic noncommunicable disease and a major risk factor for cardiovascular, cerebrovascular, and renal complications worldwide. Despite the availability of effective pharmacological and non-pharmacological treatments, low therapeutic adherence remains a persistent challenge, particularly within Primary Health Care (PHC) settings. Nurses play a central role in the longitudinal care of individuals with SAH, implementing interventions that may positively influence adherence to treatment. This scoping review aims to map the available scientific evidence on nursing interventions conducted in Primary Health Care that promote therapeutic adherence among adults with systemic arterial hypertension. The review will be conducted according to the methodological framework proposed by the Joanna Briggs Institute (JBI) and reported following the PRISMA-ScR guidelines. The Population–Concept–Context (PCC) strategy will guide the research question, focusing on adults with SAH, nursing interventions aimed at therapeutic adherence, and the PHC context. Searches will be performed in MEDLINE (PubMed), Embase, LILACS, Scopus, Web of Science, Cochrane Library, and SciELO, in addition to grey literature sources, with no restrictions on study design, language, or publication period. Study selection and data extraction will be carried out independently by two reviewers, with disagreements resolved by a third reviewer. Data will be synthesized descriptively and organized using the PAGER framework to identify patterns, advances, gaps, implications for practice, and recommendations for future research. The findings are expected to provide a comprehensive overview of nursing strategies that support therapeutic adherence in SAH, contributing to improved clinical practice, health service organization, and public health outcomes within Primary Health Care.
