Abstract
Aims. To assess whether the use of multiple cause-of-death data could improve reporting of AIDS mortality in Italy.
Method. Population-based, record-linkage study, on 3,975,431 deaths recorded in the National Registry of Causes of Death (RCoD) and 4,530 deaths recorded in the National AIDS Registry (RAIDS), during 2006-2012.
Results. The record-linkage identified 3,646 AIDS-related deaths present in both registries, 884 deaths in the RAIDS without mention of HIV/AIDS in the RCoD, and 3,796 deaths in the RCoD with mention of HIV/AIDS that were not present in the RAIDS. In the latter, in-depth analysis of multiple cause-of-death allowed the identification of 1,484 deaths that were AIDS-related. On these results, we estimated 6,014 deceased people with AIDS. Of them, 14.7% (884) were not present in the RCoD and 24.7% (1,484) derived from the RCoD only.
Conclusions. The integration of different nationwide registries allowed a more comprehensive
estimate of the impact of AIDS-associated mortality in Italy.
