Summary
This study investigates the awareness, experience, and healthcare provider warnings regarding prescription and over-the-counter medications that can impair driving (PDI) among older adults. Motivated by the increasing prevalence of polypharmacy and chronic medical conditions in the aging population, alongside the heightened risk of motor vehicle collisions (MVCs) associated with medication side effects, the research aims to determine if older drivers understand the risks their medications pose to driving safety. The study specifically examines whether demographic factors, medical history, or medication usage correlate with driver awareness and whether such awareness influences driving behaviors. The researchers conducted a telephone survey of 630 community-dwelling drivers aged 55 and older in Alabama. Participants provided detailed information on their demographics, medical conditions, current medication use, and driving habits. Medications were categorized as PDI if they had side effects such as drowsiness, dizziness, or vision impairment. The primary outcome was a composite measure of "any awareness, experience, or warning" (AEW) from healthcare providers. Statistical analyses, including logistic regression, were used to assess associations between AEW and various factors, including age, education, number of medical conditions, and driving exposure. The results revealed that awareness of PDI medications was low, with only 38.9% of respondents reporting any AEW. Awareness decreased significantly with age, particularly among those 75 and older, and was lower among individuals with less educational attainment. Crucially, there was no significant association between AEW and the number of medical conditions or the number of PDI medications taken; high-risk individuals taking multiple impairing drugs were not more likely to be aware of the risks than those taking fewer. Furthermore, while respondents with AEW were more likely to attribute driving avoidance to health issues, their overall driving exposure and general avoidance behaviors did not differ significantly from those without AEW. The study concludes that older adults, especially the oldest and least educated, are poorly informed about the driving risks associated with their medications, despite often being at the highest risk due to polypharmacy. The findings suggest that current healthcare communications are insufficient, as increased awareness does not necessarily lead to reduced driving exposure. The authors recommend that clinicians and pharmacists place greater emphasis on educating patients about PDI medications, particularly targeting high-risk groups. Enhanced patient education and improved clinician-patient communication are identified as critical steps to mitigate the risk of medication-related driving impairments in the growing older adult population.
Key finding
Only 38.9% of 630 older Alabama drivers reported any awareness, personal experience, or healthcare-provider warning about potentially driver-impairing medications, with the lowest awareness (~77% reporting no-AEW) among drivers aged 75+ despite their greater use of prescription PDI drugs.
