Background : Blood availability is an issue of concern in countries of sub‐Saharan Africa where both the demand and discard rates of blood are high. Although some degree of attention is paid when transfusion reactions occur in recipients, no information is available on donor reactions in this setting. Objectives : This study was carried out in order to obtain some data on adverse reactions (ARs) to blood donations. It would make it possible to monitor and improve the safety of the donation procedure, which constitutes a strategy towards increasing donor supply by encouraging first‐time donors to return in the absence of any negative outcomes of donation. Methods : A hospital blood bank‐based descriptive and prospective study was carried out to document ARs among 1034 blood donors from September 2010 to January 2011. A pre‐structured data collection tool was used to record the signs and symptoms observed. Results : The ARs occurred at a rate of 2·8%. The most frequent reaction was hypotension which constituted 26·62% of all ARs. Haematomas represented 18·42% while weakness and dizziness were each noted in 13·16% of donors. There was no severe vasovagal reaction. Associated factors to vasovagal reactions were first‐time donor status ( P = 0·004), female sex ( P = 0·01) and low body weight ( P = 0·02). Conclusion : Our results suggest that blood donation is a relatively safe procedure in our context. The frequency is higher than studies from developed countries. The association of AR with first‐time blood donation needs to be verified in a larger study. However, it could suggest another benefit of regular blood donation.
