Early and Frequent Psychiatric Readmissions in a Brazilian Cohort of Hospitalized Patients Between 2001 and 2013.

OBJECTIVE: To characterize the profile of patients who were readmitted for mental and behavioral disorders, in the Brazilian Unified Health System, from 2001 to 2014, and the factors associated with early and frequent readmission. METHOD: A retrospective, non-concurrent cohort study of patients admitted with a primary diagnosis of mental or behavioral disorders, from 2001 to 2014. This study selected demographic variables and clinical variables, as well as variables related to the characteristics of the hospitals. Poisson Regression methods with a robust variance estimator were used to estimate the incidence rate ratio (IRR) for each of the outcomes. RESULTS: Early readmission occurred for 6.8% of the patients and frequent readmission for 8.3%. Characteristics such as being male, younger, with a diagnosis of a bipolar disorder, and admitted to a specialized hospital show a higher IRR for early readmission. The occurrence of early readmission was the most heavily associated characteristic with an increased rate of early readmission, and the magnitude of this increase depends on the patient's age. CONCLUSION: Early and frequent readmissions are linked to patients' demographics, clinical information and health system's organization. Early readmission should be a priority in treatment planning to prevent frequent readmissions due to its strong association.

Factors associated with risk of death by suicide after psychiatric hospitalization by the Unified Health System in Brazil (2002-2015).

OBJECTIVE: To investigate overall and sex-related characteristics associated with the risk of death by suicide within 365 days of discharge in patients admitted to psychiatric hospitals in the Brazilian Unified Health System (SUS). METHOD: A non-concurrent prospective cohort of adult patients admitted to psychiatric hospitals in the SUS, from 2002 to 2015. Patients were stratified according to sociodemographic and clinical variables. Adjusted hazard ratios (aHRs) of suicide within 365 days of discharge were estimated using Cox proportional hazard regression models. RESULTS: This sample comprised 1,228,784 adult patients admitted to psychiatric hospitals. Of these, 3201 died by suicide within 365 days of discharge. The risk of suicide was positively associated with male sex, age between 18 and 29 years, living in the South region, and living in rural or intermediate municipalities. The highest risk of suicide was among patients with depressive disorders (aHR, 3.87; 95%CI, 3.41-4.38) follow by opioid-related disorders (aHR, 2.71; 95%CI, 2.00-3.67), particularly among female patients. CONCLUSION: Patients with a psychiatric hospital admission should have access to mental health care services immediately after discharge and in the long term. Findings of this study may support suicide prevention policies and have implications for clinical decisions related to patient discharge and follow-up.
