Team-Effectiveness Barriers and Solutions to Depression Screening within a Pediatric Hospital Network: A Qualitative Study.

Access to healthcare services is a core pillar for consolidating Brazil’s Unified Health System (SUS) and for ensuring the constitutional right to health [,]. Despite major institutional and regulatory advances, persistent regional and social inequalities still constrain the effective realization of this right, particularly in peripheral and hard-to-reach territories []. In the Brazilian Amazon, long distances, population dispersion, seasonal mobility constraints, and uneven health infrastructure produce a distinctive set of challenges, in which territorial vulnerability converges with enduring socioeconomic disparities [,]. Evidence accumulated over recent decades indicates that healthcare access in the Amazon is shaped not only by the nominal presence of services and professionals, but also by a network of interrelated determinants, including income, educational attainment, mobility conditions, occupational profile, and community belonging []. These factors influence patterns of service use and, consequently, the timeliness and continuity of care [,]. In rural and riverside settings, geographic distance and transportation costs are frequently compounded by infrastructural deficiencies and the precarious condition of transit routes, resulting in access that is both unequal and intermittent []. Beyond geography and material conditions, access in the Amazon is also marked by historical and social processes that structure opportunities and constraints in everyday life. Quilombola communities, for instance, have faced long-standing patterns of territorial exclusion and limited public investment, which may translate into barriers to timely care, reduced service availability, and greater dependence on irregular transportation routes [,]. In this context, “community belonging” is not merely a demographic attribute; it often reflects lived experiences of discrimination, institutional invisibility, and unequal distribution of resources that can shape care-seeking trajectories and interactions with health services [,].
