Patient-centered primary care and receipt of evidence-based alcohol-related care in the national Veterans Health Administration

Abstract

BackgroundHealth care systems are increasingly integrating screening and care for unhealthy alcohol use into primary care settings. However, gaps remain in receipt of evidence-based care after the detection of unhealthy alcohol use. Patient-centered primary care may be an important determinant of alcohol-related care receipt, but its role is underexamined. MethodsWe examined associations between previously developed, clinic-level measures of patient-centered care (indicative of medical home model implementation) and receipt of alcohol-related care in a national cohort of VA patients who screened positive for unhealthy alcohol use (defined by AUDIT-C alcohol screen of ≥5; n = 568,909) for whom brief intervention is recommended. We also assessed alcohol-related care in a subsample of these patients with a past-year alcohol use disorder (AUD) diagnosis (n = 144,511) for whom specialty addictions care and medications are recommended. The study used modified Poisson models to assess associations between measures of patient-centered care and individual-level receipt of recommended alcohol-related care. We presented prevalence ratios (PR) and marginal probabilities to illustrate relative and absolute differences, respectively, in outcomes associated with clinic-level measures. ResultsCompared to patients in the lowest-ranked clinics, patients were more likely to receive brief intervention in clinics with the highest rankings of self-management support (PR: 1.06; 95% CI: 1.10, 1.11), communication (PR: 1.08; 95% CI: 1.04, 1.12), access (PR: 1.11; 95% CI: 1.06, 1.17), and care coordination (PR: 1.09; 95% CI: 1.03, 1.15). The study also observed a greater likelihood of receiving AUD medications among those receiving care at clinics with higher ratings of comprehensiveness (PR: 1.35; 95% CI: 1.10, 1.66) and shared decision-making (PR: 1.35; 95% CI: 1.12, 1.61); higher clinic-level access ratings were associated with specialty addictions care (PR: 1.15; 95% CI: 1.00, 1.32). Patients in the clinics with the highest summary patient-centered care ratings, compared to the lowest, had higher likelihoods of receiving brief intervention (PR: 1.07; 95% CI: 1.03, 1.12) and medications (PR: 1.16; 95% CI: 1.00, 1.35). The study did not identify any other statistically significant findings. ConclusionsThis observational study found that dimensions of patient-centered care were associated with increased receipt of recommended alcohol-related care. Future studies should investigate strategies to improve patients' experience of alcohol-related care.
