Purpose:

Veterans presenting for treatment of substance use disorders (SUDs) often have multiple and serious comorbid medical conditions that affect functional health status and health care costs. Prior studies show higher rates of medical follow-up when onsite primary health care was provided to patients with SUDs within an addictions clinic (onsite care). However, no data are available on differences between onsite versus referral models of primary care delivery in terms of clinical outcomes and total health care costs.


Study summary:

Background: Veterans presenting for treatment of substance use disorders (SUDs) often have multiple and serious comorbid medical conditions that affect functional health status and health care costs. Prior studies show higher rates of medical follow-up when onsite primary health care was provided to patients with SUDs within an addictions clinic (onsite care). However, no data are available on differences between onsite versus referral models of primary care delivery in terms of clinical outcomes and total health care costs. Objectives: The objectives of this study are to compare patients with SUDs who receive onsite primary care in a VA outpatient addictions clinic to those referred for primary care to the general internal medicine clinic on: 1) medical outcomes and quality of life; 2) SUD treatment outcomes; and 3) overall health care costs. This information will assist in identifying practice guidelines for providing preventive services and treatment for acute and chronic medical conditions to individuals in SUD treatment. Methods: This study is a randomized clinical trial with two treatment conditions: 1) onsite primary care in the Addictions Treatment Center (ATC; experimental); or 2) referral primary care in the General Internal Medicine Clinic (GIMC; control). Subjects are assessed at baseline and at 3, 6, and 12-month time points. The sample includes 720 veterans, newly presenting or returning to SUD treatment, who exhibited a chronic medical condition at screening, did not have a primary care provider; and did not present with a serious medical condition requiring ongoing care in three or more organ systems. Medical status outcome measures include scores on the SF-36, and total emergency room visits and medical or surgical inpatient admissions. Substance abuse outcomes are measured by treatment retention, changes in Addiction Severity Index (ASI) scores, and self-reported alcohol use. Lastly, overall VA health care costs per subject per the 12-month period following randomization are compared across groups. The main analysis involves intent-to-treat analysis of group (onsite vs. referral) by time (3, 6, 12-month) using random effects regression models. Status: Complete. All subjects completed study interventions as of 3/31/2004. Currently data analysis is ongoing.
