HIV Testing in Community Health Center Dental Clinics

This is a cluster randomized trial among dental clinics (n=4) to evaluate whether rapid HIV testing (RHT) during dental visits improves HIV testing rates compared to referral for laboratory HIV testing. Clinics will be randomized to either RHT or referral for HIV testing for a nine-month period - HIV testing will be offered to n~6700 patients by ~ 15 dental providers (dentists and dental hygienists). Outcomes will be assessed using electronic health record reports (EHR), which will include the completion rates of HIV testing among dental patients (84 days after dental visit) and the frequency at which dental providers offer HIV testing (Upon completion of the 9-month testing period).

The objectives of this study are to:

* Compare the effectiveness of on-site rapid HIV testing versus referral to a CHC lab in increasing HIV test completion within 84 days of a dental clinic visit, using EHR data. * Assess the sustainability of the HIV testing protocol by evaluating changes in dental clinic HIV testing rates over time.
