BACKGROUND: Haemovigilance may be an important tool to improve the safety of blood transfusion practice. Its properly implementation relies on the quality of the data generated by public health services. Transfusion-associated AIDS may be considered an exclusive transfusion reaction which, in Brazil, is systematically informed. Therefore, its surveillance has been elected as a subject of study.

METHODS: The field of study encompasses 56 AIDS patients who received blood transfusion. These transfusions and their report took place in the city of Sao Paulo since 1986. All the infected patients were residents in Sao Paulo. After analyzing the viability of the investigation, whenever possible, the cases were investigated. Those confirmed transfusions were then traced. Serological tests anti-HIV results were observed in further donations. In failing that, respective donors were summoned for a retest.

RESULTS: An inconsistency and shortage of data were noticed throughout the study. Consequently, 34 (61%) of the notified cases occurred to be impossible to be investigated. In addition to this, in 7 (12%) of the cases there was a disruption of the investigation due to a failure in locating the medical records at the hospitals. Concerning transfusions, they were confirmed in 8 (53%) of the remaining. It was possible to trace 15 (83%) of units as well as obtain serological retest results of 7 (47%) of donors. No transfusion-associated AIDS case was confirmed.

CONCLUSIONS: Among other aspects, it was concluded that there is a lack of accuracy of the information available nowadays - important for an effective achievement of Haemovigilance.
