[Evaluation of the use of the International Classification of Diseases for the codification of AIDS].

The International Classification of Diseases (ICD) provides codes for all conditions and permits international comparisons of morbidity and mortality. Because it has to be used all over the world its codes are not always perfectly appropriate. There are revisions from time to time to bring up-to-date the classification. This has happened with AIDS, included in the chapter of infectious diseases in the last revision, ICD-10. The use of ICD-10 AIDS codes is here appraised. All surveillance report forms of one specialized hospital in infectious diseases, notified in 1994, have been codified, but it was found that many diagnoses could not be codified in accordance with a single ICD-10 AIDS code.
