 AB    OBJECTIVE: Study methods of assessing HIV trends in sexually transmitted
       disease (STD) clinics where blinded seroprevalence has been among the
       highest in the United States. DESIGN: Cross-sectional and retrospective
       cohort. METHODS: Reviewed computerized records of the four Miami STD
       clinics for 1987-1992. RESULTS: A total of 53,403 persons had 70,793
       tests. When testing began, 13% were HIV-positive. By 1992, 35% of all
       tests were performed on previously HIV-negative persons. This caused a
       faster decline in overall seroprevalence (to 7%) compared with
       seroprevalence among persons tested for the first time (to 9%). The
       percentage of tests performed for previously HIV-negative persons varied
       among age, race and sex subgroups, causing confounding if overall
       seroprevalence was used to compare groups. Seroconversion occurred in
       514 patients. Black women were most likely to be positive on retesting
       (4.3%). Incidence rates did not change much over time, remaining at 2.5%
       per year. CONCLUSIONS: When using a routine HIV-testing data to analyze
       trends, separate analyses should be undertaken for patients who were (or
       were not) previously tested. In these patients, the prevalence decreased
       slightly but incidence remained high, particularly among black women.
