Study Finds Medication Burden Affects Rehabilitation in Seniors
A recent study from Japan has revealed that older adults leaving the hospital with multiple medications may struggle more to regain their independence during rehabilitation. This research, published in BMC Geriatrics, focused on the impact of polypharmacy—defined as taking six or more medications regularly—on patients aged 65 and older.
The study observed 1,903 patients in a rehabilitation facility from April 2017 to March 2024. The participants were diagnosed with conditions affecting their health, such as cerebrovascular disease, motor disorders, or disuse syndrome, which results from inactivity.
Notably, 62.1% of the patients were on six or more medications at the time they left the hospital, with over 76% of them being 80 years or older. Common medications among these patients included drugs for anxiety, insomnia, constipation, and various mental health conditions.
The research indicated a significant link between polypharmacy and lower scores on the functional independence measure (FIM), a tool that evaluates how well individuals can carry out daily activities. This trend was particularly evident in those suffering from cerebrovascular disease and disuse syndrome. However, patients with motor disorders did not show the same correlation.
The findings suggested that the negative effects of multiple medications were even stronger in those over 80 and those recovering from strokes or general weakness.
In light of these results, researchers recommend that healthcare providers review and possibly reduce unnecessary medications in older patients to improve their recovery outcomes. Dr. Marc Siegel, a senior medical analyst, emphasized that while each medication may serve a purpose, the body’s ability to handle these drugs often decreases with age.
He cautioned that even common medications can have heightened effects on older adults, such as greater sedation or confusion. Additionally, the risks of drug interactions can increase, making careful monitoring by physicians essential.
Although the study provides valuable insights, it’s important to note it has limitations. The observational nature means it cannot definitively conclude that medications caused specific outcomes. Future research is needed to identify which medications most affect recovery and the best strategies for managing prescriptions in older adults.
