The Association in Elderly Hospitalized Patients, between Psychotropic Drugs and Hip Fractures Resulting from Falls

Background/Study Context: Psychotropic drug treatment has been associated with increased risk for falls and hip fractures in elderly patients. The authors examined the association between drug treatment and hip fractures resulting from falls in elderly hospitalized patients, focusing on the medications anticholinergic properties.Methods: This retrospective case-control study was conducted in an acute geriatric ward in a general medical center. Medical records, including demographic, clinical, biochemical, and pharmacological variables, of elderly patients with hip fractures from falls (N = 185), admitted during a 2-year period, were reviewed and compared with a control group (N = 187) of patients matched for age and gender and without hip fractures.Results: The usage rates of antipsychotics, antidepressants, mood stabilizers, and various nonpsychiatric medications were similar in the two groups, except for hypnotics-anxiolytics (higher rates in hip-fracture patients). The Cumulative Illness Rating Scale for Geriatrics (CIRS-G) and diastolic blood pressure constituted very modest predictors of falls (R² =.038, p =.004). There were no significant differences in the anticholinergic burden values, clinical dementia ratings, and comorbidity burden between the two groups.Conclusion: The rate of psychotropic drug use in general and their anticholinergic burden are similar in acutely admitted elderly patients with or without hip fractures. However, higher usage rate of anxiolytics found in the patients with hip fractures may indicate that this is a risk factor for hip fractures related to falls in elderly patients living in the community.
