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.
