Health Care Utilization After Paraprofessional-administered Substance Use Screening, Brief Intervention, and Referral to Treatment: A Multi-level Cost-offset Analysis.
Ontology highlight
ABSTRACT: BACKGROUND:Authorities recommend universal substance use screening, brief intervention, and referral to treatment (SBIRT) for all (ie, universal) adult primary care patients. OBJECTIVE:The objective of this study was to examine long-term (24-mo) changes in health care utilization and costs associated with receipt of universal substance use SBIRT implemented by paraprofessionals in primary care settings. RESEARCH DESIGN:This study used a difference-in-differences design and Medicaid administrative data to assess changes in health care use among Medicaid beneficiaries receiving SBIRT. The difference-in-differences estimates were used in a Monte Carlo simulation to estimate potential cost-offsets associated with SBIRT. SUBJECTS:The treatment patients were Medicaid beneficiaries who completed a 4-question substance use screen as part of an SBIRT demonstration program between 2006 and 2011. Comparison Medicaid patients were randomly selected from matched clinics in Wisconsin. MEASURES:The study includes 4 health care utilization measures: outpatient days; inpatient length of stay; inpatient admissions; and emergency department admissions. Each outcome was assigned a unit cost based on mean Wisconsin Medicaid fee-for-service reimbursement amounts. RESULTS:We found an annual increase of 1.68 outpatient days (P=0.027) and a nonsignificant annual decrease in inpatient days of 0.67 days (P=0.087) associated with SBIRT. The estimates indicate that the cost of a universal SBIRT program could be offset by reductions in inpatient utilization with an annual net cost savings of $782 per patient. CONCLUSIONS:Paraprofessional-delivered universal SBIRT is likely to yield health care cost savings and is a cost-effective mechanism for integrating behavioral health services in primary care settings.
