While central nervous system (CNS) active medications such as psychotropics and narcotic analgesics have been implicated in contributing to falls in older adults, the combined effect of multiple CNS-active medications has not been investigated.
The purpose of this study was to examine the influence, in community-dwelling elderly, of (1) taking multiple CNS-active medications on fall liability and (2) individual classes of CNS-active medications (using discrete drug classification) on the risk of falls after controlling for important confounders - age, mobility, cognition and depression.
305 community-dwelling male veterans (age : 70-104) were screened at study entry for mobility, cognition and depression.
CNS-active medications were categorized as benzodiazepines, other sedative-hypnotics, neuroleptics, tricyclic antidepressants, and opioid analgesics.
Subjects were prospectively followed for 6 months to monitor falls ; at the end of this time period, subjects were classified as fallers (at least one fall) or nonfallers.
The relationship between CNS-active drug use and falls was examined using multivariable analyses.
The risk of falls was significantly greater in CNS-active medication users as compared with nonusers.
Adjusted odds ratio for one CNS-active drug was 1.54 (95% confidence interval 1.07-2.22) and for two or more agents 2.37 (95% confidence interval 1.14-4.94). (...)
