HIV provider endorsement of primary care buprenorphine treatment: a vignette study.

BACKGROUND AND OBJECTIVES: Opioid dependence is common among HIV-infected persons in the United States. Factors associated with HIV care providers recommending buprenorphine for opioid dependence are poorly defined. Using vignettes, we sought to identify HIV provider characteristics associated with endorsing buprenorphine treatment in primary care.
METHODS: We used a cross-sectional survey of HIV providers, including 497 physicians, nurse practitioners, and physician assistants attending HIV educational conferences in 2006. Anonymous questionnaires distributed to conference attendees contained one of two vignettes depicting opioid-dependent patients. Respondents recommended type of substance abuse treatment for the vignette patient. Using logistic regression, we tested patient and provider factors associated with HIV provider endorsement of buprenorphine in primary care.
RESULTS: Sixteen percent of providers endorsed buprenorphine treatment in primary care for vignette patients. Family physicians and general internists (AOR=2.8, CI=1.1-7.1), African American providers (AOR=3.0, CI=1.3-6.8), and those with previous buprenorphine prescribing experience (AOR=4.6, CI=1.2-17.9) were more likely to endorse buprenorphine treatment in primary care.
CONCLUSIONS: HIV providers infrequently endorsed buprenorphine treatment in primary care for vignette patients. Generalist and African American providers and those with previous buprenorphine prescribing experience are more likely to endorse buprenorphine treatment in primary care. Targeting generalist and minority providers may be one strategy to promote effective integration of HIV care and opioid addiction treatment.
