Decrease in alcohol use disorder hospitalizations in Brazil: what does it mean?

Abstract

Abstract Objective To analyze the trend of hospitalizations for alcohol use disorder (AUD) in Brazil, by region, and establish its relationship with mental health care facilities. Methods Data were collected through the Brazilian Unified Health System’s (SIH/SUS) Hospital Information System (Sistema de Informação Hospitalar) and the National Register of Health Establishments of Brazil (Cadastro Nacional de Estabelecimentos de Saúde [CNES]). We used linear regression models to estimate the effect of SUS psychiatric beds and Center for Psychosocial Care (Centro de Atenção Psicossocial [CAPS]) numbers on AUD hospitalizations. Results From 2015 to 2020, 298,735 hospitalizations for AUD were recorded. Most of the patients admitted for AUD were male (88.8%). Individuals aged 60 years and older accounted for 11.7% of our cohort. The highest concentration of hospitalizations occurred in the South region (40.1%). The rate of hospitalizations per hospital bed remained relatively constant. The number of CAPS has a negative effect on SUS psychiatric beds in Brazil (average effect -22.31 [95% confidence interval {95%CI} -26.92, -17.70]). Psychiatric beds have a positive effect on AUD hospitalizations in the country (average effect 1.82 [95%CI 0.91, 2.74]). Conclusion Prioritization guidelines for other forms of care are associated with a decrease in hospitalizations for AUD, so we highlight the importance of adequate training of health care professionals for proper referral of these patients to hospital admission when necessary.
