Abstract
OBJECTIVES: to understand the macro and micropolitical interactions of care management in Primary Health Care regarding the use of nursing protocols. METHODS: qualitative research, anchored in Constructivist Grounded Theory. Thirty healthcare professionals participated in in-depth interviews conducted between 2023 and 2024. Data were analyzed and coded in two stages: initial and focused, resulting in categories and their theoretical relationships. RESULTS: the main category, "Understanding nursing protocols in macro and micropolitical interactions in Primary Health Care", emerges from six subcategories that addressed institutional partnerships, strengthening nursing, weaknesses and strengths of Primary Care, evidence-based protocols, review, training, and use of the Practical Approach to Care Kit. FINAL CONSIDERATIONS: nursing protocols transcend macro and micropolitical dimensions, expanding clinical practice and promoting care management, with impacts on strengthening primary care and nursing.
