Whole Blood Donor Deferral Causes in a Tertiary Care Teaching Hospital Blood Bank from South India

Abstract

Introduction: Suspension of eligibility of an individual to donate blood or blood components due to various causes is called deferral.This is intended to take care that removal of blood does not harm the donor and that the potential risk to the recipient due to disease conditions in donor must be kept to minimum.This cross sectional study was designed to delineate the causes for deferrals amongst whole blood donors.Methodology: This was a 1year descriptional study done in a tertiary care teaching hospital Blood Bank in South India.The various causes for deferral of the donor from donation were collected from the donor deferral register which was recorded using the regular questionnaire based interview in the registration card followed by thorough medical history elicitation and examination.The statistical analysis was performed using SPSS version 10.Results: Amongst 30711 donors who attended the blood bank for donation, deferral rate was 9.74%.Out of which there were 2487(83.11%)temporary and 505(16.89%)permanent deferrals.The most common cause for deferral was anemia in females whereas among males it was alcohol consumption in the past 12hours. Conclusion:The deferral rate in this study is comparable to the deferral rates in other centers.The data will be very essential and helpful in testing the applicability of donor selection criteria locally in different geographical settings.
