OBJECTIVES Patients living with HIV (PLWH) are predisposed to atherosclerotic cardiovascular disease (ASCVD), resulting in concomitant antiretroviral and statin use. A statin prescribing gap for PLWH has been reported, but appropriateness of statin selection and dosing (ASD) has not been described. METHODS This is a comparative, retrospective study reviewing ASD in PLWH vs. uninfected patients at two outpatient clinics within an academic medical centre. Adults > 21 years old indicated for statin therapy were included. The primary outcome was percentage of PLWH prescribed an appropriately dosed statin, accounting for clinical- and patient-related variables, compared with uninfected patients. The secondary outcome was to identify patient characteristics associated with inappropriately dosed statins. RESULTS After propensity score matching, 879 PLWH and 879 uninfected patients were included for analysis. Fewer PLWH (27.8%, n = 244) were prescribed an ASD compared with uninfected patients (40.5%, n = 356, P
