HIV rapid testing may enhance the effectiveness of a mobile HIV/sexually transmitted disease (STD) screening clinic in at-risk populations who normally do not seek care. Our goal was to determine the usability and post-test counseling rates of rapid HIV testing services for clients tested on a mobile clinic. HIV Oraquick rapid HIV-1 testing (OraSure Technologies, Inc., Bethlehem, PA) (blood) was offered to clients seeking HIV/STI counseling and testing services from the street at predetermined locations in areas of high STD morbidity, drug use, and commercial sex work. Rapid test results were available on the same day at the van within 10 minutes. Disease intervention specialists (DIS) attempted to locate and counsel positive clients who did not stay for results. By comparison, when offered at the same time, 64.5% of clients preferred Oraquick to traditional serologic testing. The post-test counseling rate for clients tested for Oraquick was 89% for infected and 93% for uninfected. By comparison, 11% of infected clients and 40% of uninfected clients tested for traditional test were post-test counseled. Clients who tested for the traditional enzyme immunoassay (EIA) test were told to return to the van in 14 days for results and post-test counseling. In the adjusted model, we also found statistically significant differences comparing clients who choose Oraquick to traditional serologic tests. These data suggest that rapid HIV testing services may enhance the effectiveness of mobile STD/HIV clinics.

Prevalence of HIV infection and AIDS cases is higher among inmates of correctional facilities than among the general population, especially for female inmates. This creates a strong need for effective HIV prevention with this population. Maryland's Prevention Case Management (PCM) program provides individual or group counseling to inmates nearing release to promote changes in risk behavior. Pretest and posttest surveys assess changes in perceived risk, condom attitudes, condom use self-efficacy, self-efficacy to reduce injection drug risk and other substance use risk, and behavioral intentions during participation in the program. Client contact logs, kept by counselors, document the number and duration of sessions, and the specific modules, completed by participants. Over a 4-year period, PCM records identified 2,610 participants in the program. Pre-intervention and postintervention data were available for 745 participants, with client contact log records available for 529 (71%) of these individuals. Significant, positive changes were found in self-reported condom attitudes, self-efficacy for condom use, self-efficacy for injection drug use risk, self-efficacy for other substance use risk, and intentions to practice safer sex post-release. Inmate populations are a crucial audience for HIV/AIDS testing, treatment, and prevention efforts. The Maryland PCM program has documented positive changes in participants' attitudes, self-efficacy, and intentions related to HIV risk, over a 4-year period.
