#67 Notable Clinical Interest
Emerging findings or policy developments worth monitoring closely.
Clinicians treating older adults with HIV need to counsel patients about cannabis use as a modifiable risk factor for falls, which carry serious consequences including fractures and loss of independence in this vulnerable population. This finding is particularly relevant since cannabis use may be increasingly common among aging HIV patients seeking symptom management, making it essential to discuss fall prevention strategies as part of comprehensive geriatric care. Understanding this association allows providers to make individualized recommendations about cannabis consumption patterns and timing relative to activities requiring balance and coordination.
This observational study from the HAILO cohort examined the association between cannabis use and fall risk in aging adults with HIV, a population vulnerable to both medication-related complications and age-related balance disorders. The researchers found that cannabis use was associated with an increased risk of subsequent falls in this cohort, likely through effects on balance, cognition, and motor coordination that may be magnified by concurrent antiretroviral medications and age-related physiologic changes. For clinicians managing older HIV-positive patients, this finding suggests that cannabis use should be assessed as a modifiable fall risk factor alongside traditional contributors such as polypharmacy, neuropathy, and deconditioning. The association is particularly relevant given increasing state-level legalization and potential patient self-medication practices in this aging population. Clinicians should counsel older HIV-positive patients considering or using cannabis about fall risk, document use in the medical record, and incorporate this information into comprehensive fall prevention strategies including home safety assessment and physical therapy when appropriate.
“This observational data from HAILO raises a legitimate concern about fall risk in our aging HIV population who use cannabis, but we need to be cautious about attribution since observational studies can’t establish causation and confounding variables like polypharmacy or disease severity are difficult to fully control for. That said, the signal is important enough that I’m counseling my older patients with HIV about potential balance and coordination effects when they’re considering cannabis, particularly those already at higher fall risk.”
💊 While this observational study from the HAILO cohort identifies an association between cannabis use and increased fall risk in aging adults with HIV, clinicians should recognize that the cross-sectional design limits causal inference and that multiple confounders—including polypharmacy, antiretroviral regimens, cognitive impairment, and unmeasured lifestyle factors—may explain or modify this relationship. The mechanisms linking cannabis to falls in this vulnerable population remain unclear; cannabinoid effects on balance, reaction time, and orthostatic tolerance could be particularly concerning when combined with HIV-related neuropathy, medication side effects, and age-related frailty. Additionally, the varying potency, route of administration, and frequency of cannabis use among study participants introduces heterogeneity that may not be fully captured in the analysis. In clinical practice, providers caring for older adults with HIV should conduct careful fall-risk assessments and explicitly discuss cannabis use during medication
