Risk factors for falling in a psychogeriatric unit

Objective To identify risk factors associated with falls in a psychogeriatric inpatient population. Design Retrospective cohort study. Setting A psychogeriatric inpatient unit in a Brown University affiliated psychiatric hospital. Participants A total of 1834 men and women who represented all admissions to the psychogeriatric inpatient unit between January 1992 and December 1995. Results Over the study period a total of 175 falls were recorded, giving a fall rate of 9.5%. Using a logistic regression model, six variables were found to be independently associated with an increased risk of falling: female gender, electroconvulsive therapy (ECT), mood stabilizers, cardiac arrhythmias, Parkinson's syndrome and dementias. Falls and ECT were associated with longer hospital stay, when adjusted for confounders including ECT. Conclusions These findings support previous results and identify ECT as a possible risk factor for falling in a hospital setting. Copyright (C) 2001 John Wiley & Sons, Ltd.
