Retrospective review: Factors impacting length of stay in Bipolar Disorder at a tertiary hospital

Abstract

Background: Bipolar disorder (BD) is a chronic, disabling mental illness that may require recurrent hospitalisation. The length of hospital stay (LOS) for BD patients is variable, and literature suggests that this is because of clinical and socio-demographic factors.

Aim: To determine the average LOS for patients admitted for BD at a hospital and its relation to clinical and socio-demographic factors.

Setting: A public tertiary hospital in South Africa.

Methods: Clinical and socio-demographic data were obtained from a retrospective record review of patient admissions at a hospital over 1 year. Length of hospital stay, defined as the duration between admission and discharge date, and other variables were retrieved.

Results: A total of 215 patients were admitted during the study period. The mean LOS was 30 days. The mean age of the patients was 35.9 years (standard deviation [s.d.] = 12.4, range 18–72 years). There were similar numbers of males and females admitted. Significantly more patients were not married (p < 0.001), unemployed (p < 0.001), and had a history of substance use (p < 0.001). Employed patients were 2.5 times more likely to have a short stay than those unemployed (p = 0.03). There was a statistically significant association between the number of comorbidities and LOS.

Conclusion: The study findings align with the literature’s results. The median length of stay was 25 days and was impacted by socio-demographic but not clinical factors.

Contribution: The study provided insight into the impact of variable factors in LOS for BD patients.
