Although psychotropic drug use has been associated with increased risk of falls in long-term care settings, this association may be confounded by the high prevalence of dementia and depression and other fall risk factors.
This question was addressed in a prospective cohort study of recurrent falls among 282 ambulatory residents of 12 Tennessee nursing homes during 1991-1992.
Eligible subjects were =65 years of age, ambulatory, able to provide study data, and expected to remain in the nursing home for =3 months.
Baseline data collected for each cohort member included symptoms of dementia (cognitive impairment and behavior problems) and depression, medication use, and other potential fall risk factors.
Falls were ascertained from facility incident reports and nursing home charts.
After controlling for symptoms of dementia and depression and other fall risk factors, the incidence density ratio for recurrent falls in baseline regular psychotropic drug users (n=178) compared with nonusers (n=104) was 1.97 (95% Cl 1.28-3.05).
The attributable risk of recurrent falls for regular psychotropic drug users was 36%, which suggests optimal management of psychopharmacotherapy is an essential component of fall prevention programs for ambulatory nursing home residents.
