Fall incident is one of geriatric syndromes that cause an increasing public health burden worldwide. The risk factors for falls incidents on geriatric patients have been identified included medication use. Benzodiazepine is a sedative hypnotic that found to be associated with an increase fall incidents. The aim of the study was to evaluate the influence of sedative hypnotics on the risk of fall incidents on geriatric patients. This was an observational study using cohort design involving 188 eligible geriatric patients comprising 94 patients who take sedative hypnotics and 94 patients who not. All pasients then underwent a test for functional mobility and fall risk using timed “up & go” test (TUG). The subjects who take ≤ 20 seconds to complete the TUG was considered to have low risk for fall incidents, whereas those who take >20 seconds was considered to have high risk for fall incidents. The results showed that the use of sedative hypnotics, sex, and number of drugs taken were associated with fall incidents on geriatric patients. Geriatric patients who use sedative hypnotics were 2.41 times higher at risk of fall incidents than those who not use sedative hypnotics (95%CI;1.12-5.17; p=0.023). Geriatric patients who take alprazolam were 2.78 times higher at risk of fall incidents compared to those who not take (95% CI: 1.49-5.19; p=0.028). Furthermore, female geriatric patients were 3.29 times higher at risk of fall incidents compared to male geriatic patients (95%CI: 1.58-6.88; p=0.001) and the use of ≥ 4 kinds of drugs were 2.76 times higher at risk of fall incidents compared to the use of <4 kinds of drugs (95%CI:1.21-6.29; p=0.015). In conclusion, sedative hypnotics is found to be a risk factor for fall incidents on geriatric patients.
