Deferral patterns of voluntary blood donors at the National Blood Transfusion Service, North East zonal centre, Maiduguri

Résumé

Appropriate donor selection in an important step in ensuring safe supply of blood and blood products. In this study deferral patterns of voluntary non-renumerated blood donors were determined at the NorthEastern Zonal Centre of the National Blood Transfusion service. The study was conducted between April 2007 and April 2009, and it involved the administration of a structured questionnaire. A total of 4032 voluntary blood donors were recruited, seven hundred and thirteen (17.7%) were temporarily deferred. The commonest reasons for deferral were low haemoglobin, self-deferral, high blood pressure, low weight and high risk behaviour. Other reasons are use of certain medications, low blood pressure and failed venopuncture. Gender analysis showed that more females were deferred for low haemoglobin and more males were self-deferred. Following donor recall, 146 of the 173 donors temporarily deferred came back to donate. These consisted of 113 deferral due to low haemoglobin, 30 self-deferred and 3 induced in risky behaviour. Effective education or counseling, the old tradition of giving haematinics and good dietary advice to those with low haemaglobin values, improved the safety and availability of blood and blood products. Donors who are self-deferred and those involved in high risk bahviour should never be persuaded to donate blood. There is also the need for a review of operational guidelines with regards the uniform acceptable cut-off point of 12.5g/dl haemoglobin value for males and females

Keywords: Donor deferral, donor health questionnaire, donor recall.

Résumé
La sélection approprie des donneurs de sang est une étape importante pour assurer l’approvisionnement en sang sécurisée et des produits sanguins. Cette étude de la fréquence de volontaire de don de sang rémunérés étaient déterminés dans la zone centrale du Nord-Est du Service National de transfusion sanguine. Cette étude était conduite entre Avril 2007 et Avril 2009, par l’aide d’un questionnaire structure. Au total 4032 donneurs de sang volontaire étaient recrutés, sept cent treize (17.7%) étaient temporairement déferrés Les raisons communs pour être déferrés incluent le taux hémoglobine faible, pression artérielle élevée, poids bas, et les risqué élevés de comportements. Autres raisons sont l’usage de certain médicaments, hypotension et échec de la venopuncture. L’analyse du gendre démontrait que les femelles étaient plus déferrées a cause du taux d’hémoglobine faible et la plupart des hommes étaient déferré volontairement. Suivant la revu des donneurs, 146 de 173 donneurs déferrés temporairement revenaient pour le don de sang. Ceux-ci consistaient de 113 cas du a l’hémoglobine faible, 30 déférés volontaires et 3 induit pour des comportements a risque. Une éducation effective ou conseille, la veille tradition de donner des hematiniques et un bon régime alimentaire a ceux ayant un taux d’hémoglobine faible, amélioraient la sécurité et la disponibilité du sang et de ses composantes. Les donneurs qui étaient déferrés et ceux ayant des comportements a risqué ne doivent pas être persuadé à faire d don de sang. Il
est nécessaire de revoir les guides opérationnelles en vue uniformisé la valeur acceptable du taux d’hémoglobine de 12.5g/dl pour les males and femelles.
