Blood donor notification rate in a blood bank in Veracruz, Mexico

Published:February 03, 2023DOI:


      Blood banks are primarily responsible for providing safe blood, but they also indirectly act to prevent the spread of infectious diseases by notifying blood donors of positive screening results. The notification process differs between countries and notifications rates are generally low. This study sought to analyze the notification rate of healthy and infection-positive donors who donated blood at CETS-Veracruz. A total of 41790 donors were analyzed, 1585 (3.79%) were positive for one or more of the screened infection markers. Only 4163 (9.96% of the total) were notified about their serology results. Of the positive donors, 157 were contacted by phone call; of them, 91 (57%) returned to the blood bank for their results. The average notification rate for positive donors was only 17.48%. The highest notification rate was for anti-HBc (26.63%), while the lowest was for HBsAg (4.17%). Age significantly influenced the return of donors: Those aged 18–24 and 25–39 years were 4.71 and 1.64 times less likely, respectively, to return for their results compared to the rate for all ages. The advice received in the pre-donation stage about the risks of transfusion-transmitted infections and the relevance of returning for results did not appear to impact donors, since the rate of notification was lower than those reported internationally. These data indicate that CETS-Veracruz should improve donor data registration and communication mechanisms to increase the notification rate, and that donor notification studies should be carried out in other Mexican blood banks to analyze the return rate at the national level.
