Access to specialized outpatiecare: an analysis of regulation in Brazilian settings

To analyze how different subnational governments, based on common national guidelines, have developed their own models for regulating access to specialized care, with varying degrees of innovation, institutionalization, and integration of telehealth. A descriptive and exploratory study with a qualitative approach that comparatively analyzes the implementation of regulations governing access to specialized care. Data were collected through document analysis, literature review, and, in some cases, interviews with key stakeholders, consolidated into detailed descriptions of each scenario to form the research corpus. Analysis was conducted using the Consolidated Framework for Implementation Research (CFIR). Experiences were selected from the municipalities of Curitiba (PR), Belo Horizonte (MG), Porto Alegre (RS), and São Paulo (SP), as well as the states of Ceará, Santa Catarina, Rio Grande do Sul, and the Federal District. The eight Brazilian experiences with outpatient regulation are characterized by diversity in organizational models, degrees of institutionalization of teleconsultation, and integration across levels of care. The adoption of technologies, access regulation protocols, and computerized systems varied across locations, influenced by structural, regulatory, and contextual factors. When integrated, teleconsultation improved the quality of referrals and increased problem-solving capacity in primary care, but its implementation remains uneven across the country. The implementation of access regulation to specialized care in the Unified Health System varied according to institutional, organizational, and technological capacities. Weaknesses were identified in the integration of health information systems in the organization and delivery of specialized care, with structural inequalities; in governance, with low standardization of protocols; limited integration between Primary Health Care and specialized care; and professional resistance to change. Regions with better outcomes integrated teleconsultation into outpatient regulation; clinical and access protocols adopted health information systems integrated with analytical intelligence resources and institutionalized regulatory guidelines. The CFIR highlighted the influence of contexts, actors, and processes, reinforcing the importance of national guidelines for improving local organizations.
