Mortality rate in patients in a long-term psychiatric care facility in Johannesburg.

BACKGROUND

Limited research exists on mortality rates and contributing factors among individuals with severe mental illness (SMI) in long-term psychiatric care, especially in low- and middle-income countries (LMICs).

AIM

To analyse mortality rates and associated factors at Solomon Stix Morewa Memorial Hospital (SSMMH), a long-term psychiatric care facility in Johannesburg, South Africa.

SETTING

SSMMH, a private facility in Selby Park, Johannesburg, has been contracted by the Gauteng Department of Health since March 2017 to provide inpatient care for SMI patients.

METHODS

A retrospective analysis was conducted on records of 406 SMI patients admitted to SSMMH from March 2017 to February 2022. Mortality rates were calculated, and associated factors were analysed using descriptive statistics and logistic regression.

RESULTS

Of the 406 participants, 34 (8%) died over five years, yielding a standardised mortality ratio (SMR) of 1.28 (95% CI: 0.85-1.71). Mortality was highest in the 60-69 years age group (SMR 2.7), with most deaths occurring in 2020-2021, likely due to COVID-19. Cardiovascular conditions were the leading cause of death (53%). Age at admission (OR: 2.35, 95% CI: 1.55-3.58) and transfer site (OR: 0.58, 95% CI: 0.42-0.81) were significant predictors of mortality.

CONCLUSION

Individuals with SMI face elevated mortality rates, with age, diagnosis, and comorbidities as key factors.

CONTRIBUTION

This study provides insights into the comprehensive management of people with SMI to reduce mortality. Further research is needed to guide psychosocial and palliative care approaches.
