Abstract Background People living with HIV (PWH) experience geriatric syndromes commonly found in much older populations and may benefit from geriatrician consultation. We aim to describe a referral-based model at the University of Colorado. Methods The Positive Aging Consultations, model, sought connect high-risk PWH ≥ 50 years old care. High-risk patients (experiencing syndromes, polypharmacy, multimorbidity, or advance care planning needs) were referred for consultation UCHealth Seniors...
