Interdisciplinarity in Primary Health Care: Strategies for Strengthening Community Health

Objective: The study aimed to analyze the role of interdisciplinarity in Primary Health Care (PHC), identifying strategies that promote the integration of different professionals and their contribution to strengthening community health. Theoretical Framework: The research was based on references from the literature on interdisciplinarity, multiprofessionalism, and interprofessionalism, highlighting the importance of the Family Health Strategy (FHS), the Expanded Family Health and Basic Care Centers (NASF-AB), and participatory management practices as central axes for the consolidation of comprehensive care. Method: This is an integrative literature review conducted in the BVS, PubMed, and SciELO databases, with articles published between 2015 and 2025 in Portuguese, English, and Spanish. Initially, 263 works were identified, of which 31 met the inclusion criteria according to the PRISMA-ScR protocol. Results and Discussion: The findings indicated that systematic meetings, integrated protocols, matrix support, continuing education, and integrative practices are key strategies for interprofessional cooperation. Despite barriers—such as the shortage of human resources and the persistence of hierarchical models—facilitators stand out for their positive impact on health indicators, therapeutic adherence, and user satisfaction. Implications of the Research: The study provides insights for managers, professionals, and public policymakers, outlining paths for the consolidation of interdisciplinarity as a structuring strategy of Primary Health Care. Originality/Value: The research contributes by systematizing current evidence on interdisciplinary practice, reinforcing its value for equity, comprehensiveness, and efficiency of the Unified Health System.
