Background:
Chicago Department of Public Health (CDPH) STI Specialty Clinics offer confidential and anonymous HIV testing to all persons presenting for care. Objectives:
To describe changes in HIV antibody testing performed at CDPH STI clinics between 2007 and 2008. Methods:
HIV testing data from 2007-2008 were analyzed from the implementation of routine HIV rapid testing in the municipal STI Specialty Clinics. Results:
In 2007, 15,847 HIV antibody tests were performed. The majority (90%; 14,267/15,847) were conventional antibody tests; 10% (1,580/15,847) were rapid antibody tests. In 2007, 2.1% of persons tested by HIV rapid antibody test received a positive HIV diagnosis, and <1% were positive by conventional method. In 2008, 17,773 HIV antibody tests were performed. Of 17,773 tests, 16,506 (93%) were rapid antibody tests and 1,267 (7%) were conventional antibody tests. Approximately 1% of persons tested were positive by HIV rapid test (161/16,506), while 0.1% (2/1,267) were positive by conventional antibody testing method. Between 2007 and 2008, the number of HIV tests performed increased by 12%. HIV rapid testing increased by 945% (from 1,580 tests in 2007 to 16,506 tests in 2008) while conventional testing decreased by 91% (14,267 tests in 2007 versus 1,267 tests in 2008). All (100%) persons who tested HIV positive by rapid antibody test received their preliminary positive test result as compared to 75% (100/133) of HIV positive persons who received their confirmatory test results in 2007. Conclusions:
CDPH successfully integrated HIV rapid testing throughout the Chicago municipal STI clinics, thereby instituting the provision of same-day test results and eliminating the HIV test result disclosure visit. Implications for Programs, Policy, and/or Research:
STI clinics can integrate HIV point-of-care testing into their normal clinic screening practices without compromising the number of individuals receiving testing or the number of HIV positives identified.
