Hypnotic drug use and rehabilitation outcomes in post-acute geriatric hip fracture patients: A retrospective study

Introduction : The use of hypnotic drugs is common in the elderly and is associated with negative health outcomes. Our aim was to evaluate the prevalence of hypnotic drug usage amongst hip fracture patients undergoing a rehabilitation program and investigate any potential associations between hypnotic drug use and rehabilitation outcomes in a post-acute care setting. Methods : A retrospective analysis of 440 geriatric hip fracture patients was conducted from 1/1/2019-12/2021 in a geriatric rehabilitation center. The main outcome measures were the Functional Independence Measure (FIM), the motor FIM effectiveness and length of stay (LOS). Results : Two hundred and twenty-eight (51.7%) patients out of the entire cohort (440)), were prescribed hypnotic drugs. These patients exhibited a significantly lower rate of diabetes (p=0.025), a higher rate of depression (p=0.003), and lower albumin levels (p=0.023) upon admission to rehabilitation in comparison to untreated patients. No significant differences were observed between the two patient groups in functional rehabilitation outcomes or LOS. Moreover, no correlation was established between the hypnotic drug burden during rehabilitation and the outcome measures. Furthermore, no significant differences were found between patients treated with hypnotic drugs on admission and those who were prescribed these drugs during rehabilitation. The type of hypnotic drug did not affect these results. Conclusion : The use of hypnotic drugs by elderly individuals undergoing a rehabilitation program after a hip fracture is unlikely to have an adverse impact on their short-term rehabilitation outcomes. Consequently, there may not be an immediate necessity to discontinue these drugs upon admission. Nevertheless, the use of hypnotic drugs should be approached with caution and minimized whenever possible due to an increased fall risk and other adverse effects.
