A Multidisciplinary Healthy Aging Program in Comprehensive HIV Care: Multidomain Screening, Clinical Interventions, and Cardiometabolic Risk Management

Background: People living with HIV (PLWH) are increasingly reaching older ages due to the success of antiretroviral therapy. However, aging with HIV is associated with increased risk of multimorbidity, neurocognitive impairment, frailty, psychosocial stress, and functional decline. Multidomain geriatric screening framed within an Age-Friendly 4Ms Framework (Mentation, Medication, Mobility, What Matters Most) and consideration of multi-complexity may help identify aging-related vulnerabilities and guide multidisciplinary care with greater impact on patient outcomes. However, real-world implementation of such programs within HIV clinical settings remains limited. Methods: We conducted a retrospective analysis of adults aged ≥50 years enrolled in a multidisciplinary Healthy Aging Program within a large, integrated HIV care system. Multidomain screening assessments included cognitive evaluation (Montreal Cognitive Assessment), mental health screening (PHQ-2, GAD-2), functional assessment (Katz ADL, Lawton IADL), frailty screening (Edmonton Frail Scale), and intrinsic capacity domains using the WHO Integrated Care for Older People (ICOPE) framework. Screening results, referrals, clinical interventions, and cardiometabolic risk management measures were extracted from clinical program databases and electronic medical records. Results: A total of 317 adults aged ≥50 years completed multidomain screening. Participants had well-controlled HIV infection, with viral suppression in 96.2% and a median CD4 count of 660 cells/mm3. Despite this, aging-related vulnerabilities were common. Overall, 78.4% of participants had at least one abnormal screening domain. Cognitive impairment was identified in nearly half of individuals screened, including mild impairment in 39.8% and moderate impairment in 8.7%. Functional limitations were identified in 10.1% of participants, while anxiety symptoms were present in 9.5%. Sensory impairments were common, including vision impairment in 36.5% of participants. Polypharmacy was prevalent, with 33.2% of participants prescribed five or more chronic medications. Screening frequently generated multidisciplinary referrals, including behavioral health services (42.3%), social work support (42.9%), and pharmacist-led cardiometabolic risk review (56.8%). Age-stratified analyses demonstrated similar prevalence of screening abnormalities across age groups, including individuals aged 50–59 years. Modest improvements in cardiometabolic preventive care were observed during follow-up. Statin utilization increased from 65.6% at baseline to 70.0% at 12 months, and LDL cholesterol declined modestly during the observation period. Conclusions: Multidomain screening integrated into routine HIV care identified a high prevalence of aging-related vulnerabilities among PLWH aged ≥50 years despite excellent virologic control. These findings suggest that aging-related risk in HIV is not adequately captured by chronological age alone and support early, universal implementation of multidomain screening within HIV care models.
