Unique Identifier : AIDSLINE ICA10/94370230 AB OBJECTIVE: To evaluate the reliability of the assignment of AIDS cases to HIV transmission categories (e.g., intravenous drug users, homosexual and bisexual men) in national surveillances. METHODS: Reproducibility of transmission categories was assessed by means of kappa (K) statistics in 728 Italian AIDS cases (637 males and 91 females) for whom this type of information derived from two independent sources: the Italian AIDS Registry, RAIDS, the national compulsory notification scheme, and the Italian Cooperative Group on AIDS and Tumours, GICAT. RESULTS: A good degree of reproducibility (K > 0.80) emerged for intravenous drug users and recipients of blood and blood products in both sexes and for homosexual and bisexual men. Conversely, the concordance was poor for heterosexual and other/undetermined transmission categories, especially among males (K = 0.40 and K = 0.21, respectively). DISCUSSION AND CONCLUSIONS: These results suggest that the reliability of the classification of some transmission categories is unsatisfactory and that the present definition of at risk heterosexual partners in Italy may lead to a gross underestimation of the proportion of AIDS cases acquired heterosexually. Furthermore, as the magnitude of AIDS epidemic increases, national statistics may need to abandon the report of transmission category for each case and concentrate on the monitoring of AIDS diagnoses and HIV-related deaths.
