Hospitalizations in older adults from the Zona da Mata of Minas Gerais, Brazil: data from the Unified Health System, 2016–2018
Main Article Content
Abstract
Introduction: The growing older population increases proportionately the demand for hospital care due to the increase in health problems. Objective: To estimate the prevalence and incidence of hospitalizations, and to investigate associated factors in older adults from the Zona da Mata of Minas Gerais, Brazil, between 2016-2018. Secondly, to provide a more comprehensive epidemiological overview of hospitalizations, the following were estimated: monthly hospitalization rate; hospital mortality rate; frequency of hospitalizations according to diagnosis, hospitalizations for conditions sensitive to primary care and in-hospital death; and hospital costs. Methods: This is an ecological and descriptive-analytic study. Data were obtained from the Brazilian Hospital Information System (SIH/SUS). Results: The prevalence of hospitalizations was 35.1% (31.2% in women and 39.7% in men). The monthly rate of hospitalizations was higher in older men when compared with older women (Rate-Ratio=1.35 [95% CI=1.27-1.43]) and adult men between 40–59 years (Rate-Ratio=2.42 [95% CI=2.26-2.58]). The cumulative incidence of hospitalization was 144/1,000 older persons (125/1,000 women and 169/1,000 men). Factors significantly associated with hospitalizations were: male sex (PR=1.52 [95% CI=1.11-2.08]); hospitalization in surgical bed (PR=1.93 [95% CI=1.05-3.56]); absence of death (PR=1.94 [95% CI=1.03-3.65]); and hospital stay ≥15 days (PR=0.71 [95% CI=0.54-0.95]). The cost of hospitalizations was R$ 220,8 million (mean of R$ 201,700/day). Conclusion: The findings strengthen the need for preventive healthcare for the older population living in the Zona da Mata of Minas Gerais and alert managers to the substantial socioeconomic impact of hospitalizations.
