Adverse reactions to blood donations: the READ project.
BACKGROUND
In 2006 in Italy 2,404,267 donations of blood components were made by 1,539,454 donors; approximately 55% of the donations were collected directly by Transfusion Structures (TS), while about 45% were collected in Donation Centres managed by Associations and Federations of Donors. The aim of the READ (Rilevamento Eventi Avversi alla Donazione) project is to create a network of TS to test a standardised system for monitoring adverse events (AE) related to blood donations.


METHODS
Shared, standardised data collection forms, compatible with the forms produced by the ISBT-EHN, were prepared. Two types of form were used: (i) a form to collect data on single events (READ 1), to be used at the individual collection sites; (ii) a form for processing the data collected by each TS (READ 2).


RESULTS
Between February and August 2008 six TS collected data related to the donation of 89,332 units of blood. Overall, 523 AE were recorded. The AE occurred in 0.59% of the donations. The mean duration of the symptoms was 17 minutes. Fifteen percent of the symptoms were related to the venipuncture (mainly haematomas) and 77% to vasovagal AE. The AE were defined severe (grade C) in 47 cases. The donations in which AE were recorded were completed in 81% of the cases; 59% of the AE did not require treatment. Three donors were monitored briefly (for less than 4 hours) in hospital.


CONCLUSIONS
The use of standardised forms enabled the collection of data that could be analysed. Some problems related to the performance of the haemovigilance programme did, however, emerge: (i) organisational problems, (ii) limited sensitivity, (iii) inadequate training, and (iv) poorly defined responsibilities. These problems must be resolved at various levels: local, regional and national.
