 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.
