Background. Rapid HIV testing could increase routine HIV testing. Most previous studies of rapid testing were conducted in acute care settings, and few described the primary care providers’ perspective. Objective – To identify characteristics of general internal medicine physicians with access to rapid HIV testing, and to determine whether such access is associated with differences in HIV-testing practices or perceived HIV-testing barriers. Design – Web-based cross-sectional survey conducted in 2009. Participants - 406 physician members of the Society of General Internal Medicine who supervise residents or provide care in outpatient settings. Main measures. Surveys assessed provider and practice characteristics, HIV-testing types, HIV-testing behavior, and potential barriers to HIV testing. Results. Among respondents, 15% had access to rapid HIV testing. In multivariable analysis, physicians were more likely to report access to rapid testing if they were non-white (OR 0.45, 95% CI 0.22, 0.91), had more years since completing training (OR 1.06, 95% CI 1.02, 1.10), practiced in the Northeastern US (OR 2.35; 95% CI 1.28, 4.32), or if their practice included a higher percentage of uninsured patients (OR 1.03; 95% CI 1.01, 1.04). Internists with access to rapid testing reported fewer barriers to HIV testing. More respondents with rapid than standard testing reported at least 25% of their patients received HIV testing (51% versus 35%, p =.02). However, access to rapid HIV testing was not significantly associated with the estimated proportion of patients receiving HIV testing within the previous 30 days (7.24% vs. 4.58%, p=.06). Conclusion. Relatively few internists have access to rapid HIV testing in outpatient settings, with greater availability of rapid testing in community-based clinics and in the Northeastern U.S. Future research may determine whether access to rapid testing in primary care settings will impact routinizing HIV testing.
