Profiles, correlates, and risk of death among patients with mental disorders hospitalized for psychiatric reasons

Abstract

This study identified profiles of hospitalized patients with mental disorders (MD) based on their 3-year hospitalization patterns and clinical characteristics and compared sociodemographic profiles and other service use correlates as well as risk of death within 12 months after hospitalization. Quebec (Canada) medical administrative databases were used to investigate a 5-year cohort of 4,400 patients hospitalized for psychiatric reasons. Latent class analysis, chi-square tests and survival analysis were produced. Three profiles of hospitalized patients were identified based on hospitalization patterns and other patient characteristics. Profile 3 patients had multiple hospitalizations and early readmissions, worst health and social conditions, and used the most outpatient services. Profiles 2 and 1 patients had only one hospitalization, of brief duration in the case of Profile 2 patients, who had mainly common MD and made least use of psychiatric care. All Profile 1 patients were hospitalized for serious MD but received least continuity of physician care and fewest biopsychosocial interventions. Risk of death was higher for Profiles 3 and 2 versus Profile 1 patients. Interventions like early follow-up care after hospitalization for Profile 3, collaborative care between general practitioners and psychiatrists for Profile 2, and continuous biopsychosocial care for Profile 1 could be greatly improved.
