HIV-infected patients with substance use experience suboptimal health outcomes, possibly because of variations in care. OBJECTIVES: To assess the association between substance use and the quality of HIV care (QOC) received. RESEARCH DESIGN: Retrospective cohort study. SUBJECTS: HIV-infected patients enrolled in the Veterans Aging Cohort Study. MEASURES: We collected self-report substance use data and abstracted 9 HIV quality indicators (QIs) from medical records. Independent variables were unhealthy alcohol use (AUDIT-C score ≥4) and illicit drug use (self-report of stimulants, opioids, or injection drug use in past year). Main outcome was the percentage of QIs received, if eligible. We estimated associations between substance use and QOC using multivariable linear regression. RESULTS: The majority of the 3410 patients were male (97.4%) and black (67.0%) with a mean age of 49.1 years (SD = 8.8). Overall, 25.8% reported unhealthy alcohol use, 22% illicit drug use, and participants received 81.5% (SD = 18.9) of QIs. The mean percentage of QIs received was lower for those with unhealthy alcohol use versus not (59.3% vs. 70.0%, P < 0.001) and those using illicit drugs vs. not (57.8% vs. 70.7%, P < 0.001). In multivariable models, unhealthy alcohol use (adjusted β-2.74; 95% confidence interval:-4.23 to-1.25) and illicit drug use (adjusted β-3.51; 95% CI:-4.99 to-2.02) remained inversely associated with the percentage of QIs received. CONCLUSIONS: Although the overall QOC for these HIV-infected Veteran patients was high, gaps persist for those with unhealthy alcohol and illicit drug use. Interventions that address substance use in HIV-infected patients may improve the QOC received.

Objective: To determine the association between HIV infection and other risk factors for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Design: Longitudinal, national Veterans Aging Cohort Study including 43 618 HIV-infected and 86 492 uninfected veterans. Methods: AECOPD was defined as an inpatient or outpatient COPD ICD-9 diagnosis accompanied by steroid and/or antibiotic prescription within 5 days. We calculated incidence rate ratios (IRR) and 95% confidence intervals (CI) for first AECOPD over 2 years and used Poisson regression models to adjust for risk factors. Results: Over 234 099 person-years of follow-up, 1428 HIV-infected and 2104 uninfected patients had at least one AECOPD. HIV-infected patients had an increased rate of AECOPD compared with uninfected (18.8 vs. 13.3 per 1000 person-years, P < 0.001). In adjusted models, AECOPD risk was greater in HIV-infected individuals overall (IRR 1.54; 95% CI 1.44-1.65), particularly in those with more severe immune suppression when stratified by CD4 cell count (cells/ml) compared with uninfected (HIV-infected CD4+ < 200: IRR 2.30, 95% CI 2.10-2.53, HIV-infected CD4+ ≥ 200-349: IRR 1.32, 95% CI 1.15-1.51, HIV-infected CD4+≥350: IRR 0.99, 95% CI 0.88-1.10). HIV infection also modified the association between current smoking and alcohol-related diagnoses with risk for AECOPD such that interaction terms for HIV and current smoking or HIV and alcohol-related diagnoses were each significantly associated with AECOPD. Conclusion: HIV infection, especially with lower CD4+ cell count, is an independent risk factor for AECOPD. Enhanced susceptibility to harm from current smoking or unhealthy alcohol use in HIV-infected patients may also contribute to the greater rate of AECOPD.
