Introduction: In Brazil, hospitalizations of the elderly population remain predominantly driven by Non-Communicable Chronic Diseases , particularly cardiovascular, respiratory illnesses, and neoplasms. These conditions account for the largest percentages of admissions and concentrate a significant portion of the healthcare system's costs. Objective: This study aimed to analyze the main causes of hospital admissions and the associated costs between 2019 and 2023, based on records from the SUS Hospital Information System (SIH/SUS). Methods: This was an ecological and descriptive study, grounded in the analysis of secondary data. All national records of hospitalizations for individuals aged 60 years or older were considered, encompassing sociodemographic, clinical, healthcare utilization, and economic variables. Results: The findings indicated that diseases of the circulatory system accounted for approximately 38% of elderly hospitalizations, followed by respiratory diseases (22%) and neoplasms (18%). The average cost per hospitalization was approximately R$ 3,500.00, totaling 45% of the hospital expenditures during the period. Regarding the average length of stay, the elderly hospitalized due to respiratory illnesses remained for about 10 days, while those admitted for neoplasms exceeded 12 days. It was also observed that heart failure exhibited a rehospitalization rate close to 25%, reflecting the fragility of the hospital-to-home care transition. Conclusion: It is concluded that the study achieved its objective by analyzing the main causes of hospital admissions and the associated costs between 2019 and 2023, based on SIH/SUS records. The results reinforce that reducing these admissions and their costs depends on integrated and preventive public policies aimed at strengthening primary care, expanding rehabilitation, and ensuring continuous follow-up of older adults, thereby promoting active and healthy aging in Brazil.
