[BDSP. Notice produite par INIST-CNRS vR0xx740. Diffusion soumise à autorisation]. Objectives. This study examined the reliability of the first positive HIV test date reported in the U.S. HIV/AIDS Reporting System (HARS). This date is essential to determine case counts for resource allocation for HIV treatment and prevention efforts. Methods. The dates of first positive HIV tests reported by individuals with HIV in an interview survey conducted in 16 states (n=16,394, interviewed 1995-2002) were compared with the dates of HIV diagnosis reported to HARS. The percentage of agreement for the year of diagnosis and the weighed kappa (k) with 95% confidence intervals (CIs) was calculated. Results. Self-reported year of diagnosis agreed with the year of diagnosis in HARS for 56% of date pairs (k=0.69 ; 95% Cl 0.68,0.70) ; 30% reported an earlier diagnosis year. Agreement differed by sex, age, race, exposure, and reason or place of testing (p<. lower agreement was found when the self-reported diagnostic test anonymous cl compared with confidential tests also for cases first reported aids hiv not as well participants interviewed three years or more after their hars diagnosis date those within one year than of in almost all groups however earlier recorded hars. conclusion. many diagnoses may have occurred additional studies need to determine mechanisms adequately capture dates>
