ABSTRACT:
Global health emergencies, climate change and persistent social inequalities have intensified the need for integrated and intersectoral health surveillance systems. In Brazil, the National Health Surveillance Policy (PNVS) establishes guidelines for territorialized, comprehensive and coordinated surveillance actions; however, its implementation remains challenged by institutional fragmentation, limited intersectorality and insufficient integration with Primary Health Care (PHC). This study aims to analyze the implementation of the PNVS through a One Health perspective, exploring the potential of the Cooperative Intelligence Platform for Primary Health Care (PICAPS) as a strategic digital tool to strengthen intersectoral coordination and evidence-based decision-making in health surveillance. A mixed-methods case study was conducted, combining an integrative literature review on One Health, health surveillance and cooperative intelligence with qualitative data from semi-structured questionnaires applied to health surveillance and PHC managers and professionals. Quantitative analysis of secondary data from national health information systems (DATASUS) complemented the study. Data were analyzed considering the Social Determinants of Health and the Sustainable Development Goals framework. The analysis focuses on how PICAPS’ organizational and technological elements contribute to integrating human, animal and environmental health information, fostering cooperation among institutional actors and supporting territorial intelligence. As a product, the study proposes a monitoring instrument based on cooperative intelligence to support surveillance planning, emergency response and policy implementation. Expected results include identifying strengths and gaps in PNVS implementation, demonstrating the contribution of cooperative digital platforms to intersectoral governance and enhancing integration between health surveillance and PHC. The findings aim to support more equitable, integrated and sustainable surveillance systems, contributing to the operationalization of One Health principles within national public health policies.
