Promotion of mental health in primary health Care: Interdisciplinary care and the re-signification of care practices

The promotion of mental health in Primary Health Care (PHC) is configured as a strategic axis for the consolidation of comprehensive, territorialized, and user-centered care models, especially in view of the increase in psychological distress and the complexity of psychosocial demands. The objective of this study was to analyze, based on the scientific literature, to analyze the interdisciplinary strategies used in the promotion of mental health in PHC and their contribution to the re-signification of care practices. This is an integrative literature review, conducted in the PubMed/MEDLINE database, with a time frame of the last five years, including articles in Portuguese, English, and Spanish. The selection followed systematized steps, resulting in the final inclusion of four studies. The results showed that interdisciplinary work strengthens the comprehensiveness of care, expands access, and qualifies mental health practices through strategies such as matrix support, the Singular Therapeutic Project, collective activities, expanded welcoming, and articulation with the Psychosocial Care Network. It was also observed that such practices contribute to reducing the fragmentation of care, confronting the biomedical model, and expanding the clinic in the territory. It is concluded that interdisciplinarity constitutes a central element for the promotion of mental health in PHC, favoring the re-signification of care practices and the consolidation of more humanized, resolutive, and SUS-principle-aligned care models.
