OBJECTIVES: To characterize the real-world operation of the adrenal insufficiency clinical protocol (PCDT-IA) in Brazil's Unified Health System (SUS) - utilization, medication adherence, equity, and clinical outcomes -to inform the ongoing protocol update by the National Committee for Health Technology Incorporation (CONITEC).
METHODS: Observational study (descriptive, longitudinal, and ecological) using DATASUS public administrative microdata and CMED/PMVG price lists (2024-2025). We included individuals with a medication authorization (APAC) for fludrocortisone and a primary ICD-10 code of E27.1-E27.4. Adherence was measured by the Proportion of Days Covered (PDC). Demographics, self-reported race/skin color, hospitalizations (SIH-SUS), and deaths (SIM) were analyzed; inter-state variation and racial equity were benchmarked against the 2022 national Census.
RESULTS: In 2024, the PCDT-IA covered 1,345 unique patients (54.7% women; median age 53 years; 68.7% White, 25.8% Mixed-race, 3.7% Black), with 9,414 authorizations and an estimated minimum cost of ~US$0.37 million (R$1.94 million; median US$278/patient [R$1,441]) (converted at US$1 = R$5.18; June 2026). Median PDC was 0.725, and only 42.3% achieved PDC ≥80%. Adherence varied nearly 90-fold across neighboring states (Rio Grande do Sul: 0.9% vs. Paraná: 83% with PDC ≥80%). Black patients were markedly underrepresented (3.7% vs. 10.2% expected; gap ≈87 patients) and, once enrolled, faced higher discontinuation risk (adjusted HR 1.68; 95% CI 1.15-2.45). In-hospital lethality was 4.5% (9/201); of 68 deaths coded to E27.x, ~59 (87%) occurred outside hospital.
CONCLUSIONS: A single national protocol effectively functions as multiple local programs. Suboptimal adherence, racial inequity in access, and substantial out-of-hospital mortality - despite the protocol absorbing only 0.5% of analyzed pharmaceutical spending - signal managerial attention disproportionate to clinical severity. The update should embed equity indicators, minimum operational standards, and active surveillance.
