Many older adults depend on medications to manage their health, but some drugs can cause serious side effects, especially those that impact brain function. These include antipsychotics and benzodiazepines, commonly prescribed to treat anxiety, sleep issues, or behavioral symptoms. While they can be beneficial in certain situations, these drugs may also lead to confusion, fall risks, or even hospitalization.
A recent study conducted by UCLA researchers found that these medications are often initially prescribed in hospital settings rather than during routine doctor visits. The study’s findings, published in JAMA Network Open, focused on adults aged 66 and older, many of whom already experienced some degree of cognitive decline. Cognitive impairment covers a spectrum from mild memory issues to more severe conditions like dementia, making these individuals particularly vulnerable to brain-related medication side effects.
Researchers examined data spanning over a decade, from 2008 to 2021, combining information from a national health study with Medicare records to trace when and where patients first received prescriptions for certain brain-impacting drugs. These medications included antipsychotics, benzodiazepines, sleep aids, and anticholinergics.
The data revealed a striking pattern: a significant portion of these drugs were first prescribed in acute care environments such as emergency rooms, hospitals, or post-acute care settings like nursing homes. Interestingly, these prescriptions were more common than what might be expected based on how frequently patients visited these settings. This trend was especially pronounced among patients with dementia. For instance, nearly half of all antipsychotic prescriptions for dementia patients originated in hospital or similar settings, despite these patients only having a smaller percentage of total healthcare visits there.
This pattern suggests that initial medication starts often occur during hospital stays, potentially leading to long-term use even after patients leave these environments. Alarmingly, many patients continued taking these drugs for over a year, raising concerns about prolonged exposure and heightened risks in the aging population.
The study also highlighted that individuals with more serious cognitive problems were disproportionately prescribed these medications. Approximately 20% of dementia patients received new prescriptions in hospitals or similar facilities, prompting questions about whether these drugs are always necessary or if safer alternatives could be considered.
The researchers emphasize that these findings present a critical opportunity for change. Targeted efforts to reduce unnecessary or risky prescriptions should focus on hospital and nursing home settings—key points where these medications are often initially prescribed. Intervening at these stages could meaningfully decrease long-term, potentially harmful use.
However, the study has some limitations. For example, it assumes the last healthcare setting visited is where the prescription was initiated, which may not always be accurate. Despite this, the large sample size and consistent findings lend credibility to the results.
Ultimately, the research underscores how the location of prescribing can profoundly influence a patient’s health trajectory. In particular, hospitals and similar settings appear to be significant starting points for medications that affect the brain, especially among older adults with cognitive impairment. By focusing on these environments, healthcare professionals may reduce unnecessary medication use and improve safety for vulnerable populations. While further research is needed, this study offers a clear path forward for enhancing medical practices and patient care.
