- Abstract
<bold>Objective: </bold>Many patients with severe recurrent mental illness are approaching late life; however, little is known about psychiatric re-hospitalization in this population. Our objective was to identify predictors of psychiatric re-hospitalization.<bold>Methods: </bold>This was a retrospective cohort study of all 226 geriatric patients (age ≥65 years) admitted to a tertiary care Canadian inpatient psychiatric unit between 2003 and 2008. The main outcome was psychiatric re-hospitalization in 5-year follow-up post-discharge (e.g. 2008-2013 if a patient had been first admitted in 2008). Multivariate Cox regression analyses were used to identify potential predictors of re-hospitalization.<bold>Results: </bold>Over 5-year follow-up, 32.3% (73/226) required psychiatric re-hospitalization. Prior lifetime history of psychiatric admission, currently living in a supervised setting and bipolar disorder diagnosis all independently predicted a lower time to psychiatric re-hospitalization (HRs > 2.0, p < 0.05).<bold>Conclusions: </bold>The rate of psychiatric re-hospitalization is high in older adults admitted for severe mental illness. Clinicians should be aware of the especially high rates of re-hospitalization in geriatric psychiatric inpatients with bipolar disorder, previous psychiatric admissions, or those living in a supervised setting. Future research could investigate approaches to prevent psychiatric re-hospitalization in these vulnerable sub-populations.
