Mortality in the era of deinstitutionalization

Area of Science:

• Psychiatry
• Public Health
• Epidemiology

Background:

• Inpatient psychiatric treatment is a critical intervention for individuals with severe mental illness.
• Understanding long-term mortality risks in this population is essential for improving patient care and public health strategies.
• Previous research indicates varied mortality patterns among psychiatric patient groups.

Purpose of the Study:

• To investigate the 3.5-year mortality rate among 1,033 psychiatric patients post-inpatient treatment.
• To identify specific causes of death and demographic factors associated with heightened mortality risk.
• To compare cancer mortality between alcoholic and non-alcoholic psychiatric patients.

Main Methods:

• Utilized standardized mortality ratios (SMRs) to assess mortality risk in a cohort of 1,033 psychiatric patients.
• Analyzed mortality data over a 3.5-year period following a 1-year inpatient treatment phase.
• Compared observed death rates against expected rates for various causes of death and demographic subgroups.

Main Results:

• Elevated mortality was observed for accidents, suicides, and pneumonia.
• Cancer mortality was significantly higher among alcoholic patients compared to non-alcoholic patients.
• Young male schizophrenic patients and female alcoholics exhibited particularly young ages at death.
• Male patients with affective disorders showed the highest mortality risk associated with diagnosis.

Conclusions:

• Psychiatric patients, particularly those with specific diagnoses and substance use disorders, face elevated mortality risks.
• Targeted interventions addressing suicide prevention, accident risk, pneumonia, and cancer in alcoholic patients are crucial.
• Further research is needed to understand the underlying mechanisms and develop effective preventative strategies for these high-risk groups.
