[Haemovigilance donors: methods and results]

There is no official definition of haemovigilance donors. However, it concerns the observation and management of Serious Adverse Events observed in blood donors (SAEDs), Post Donation Informations (PDI), and donor epidemiologic survey. The French Decree of 1 February 2006 imposes the declaration of the SAEDs. In 2006, 196 SAEDs were notified for 2599978 donations (7.5/100,000 donations). The incidence of the SAEDs was of 7/100,000 whole blood donations and 10.7/100,000 aphaeresis donations. Donors that are more susceptible to present a SAED are: women, women under 30, repeat donor and aphaeresis donor. For 2/3 of donors having presented a SAED, a medical consultation was prescribed and 1/3 was hospitalized. Vasovagal reaction is the most frequent category. Seven thousand three hundred and sixty one PDI were notified in 2005. The risks of infection represented the principal cause (mainly ENT). Concerning donor epidemiologic survey, the viral residual risk clearly decreased since 1992 and for the period of 2003-2005 it 1/2600000 for HIV, 1/6500000 for HCV and 1/1000000 for HBV. The first national data already give useful information. This information will permit a better care of blood donors and of blood component recipients as well.
