Abstract
Although recurrent falls during hospitalization lead to discharge to nursing homes, their association with medications has not been comprehensively assessed. We aimed to assess risk factors for recurrent falls focusing on medications during hospitalization in an acute-care setting. This retrospective descriptive study was conducted in Tokyo Women’s Medical University, Medical Center East. Patients who experienced a fall during hospitalization were included and the incidence of recurrent falls was assessed during hospitalization. Multivariate logistic regression analysis was performed to assess the relationship between recurrent falls and medications and to calculate odds ratio and 95% confidence interval. Sensitivity analysis was performed on data stratified by sex or age. This study included 124 patients with an incidence of 20 (16%) recurrent falls. Multivariate logistic regression analysis revealed that selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, and noradrenergic and specific serotonergic antidepressants were associated with recurrent falls (odds ratio = 5.98, 95% confidence interval: 1.38–25.9, p = 0.02). Additionally, selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, and noradrenergic and specific serotonergic antidepressants were significant risk factors for recurrent falls in women and those aged > 80 years. Selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, and noradrenergic and specific serotonergic antidepressants were associated with an increased risk of recurrent falls during hospitalization in an acute-care setting. Clinicians should pay attention to patients receiving selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, and noradrenergic and specific serotonergic antidepressants, especially women and aged > 80 years old.
