Analysis of the reasons for deferral of prospective blood donors in a Tertiary Care Hospital in North India

Abstract

Background: Blood donor deferral is a painful and sad experience for the donor, organizer as well as screening doctors. The rate and reasons of deferral differ from region to region and center to center. The shortage of safe blood donors is frequent, and it is important to understand the causes of deferral in voluntary donors. The aim of this study was to analyze the incidence of donor deferral, causes of deferral, and apply relevant findings to modify the recruitment strategy to decrease the temporary deferral rate. This strategy could increase the pool of voluntary donors without compromising on the quality of the blood and safety of the recipient. Materials and Methods: Data from voluntary blood donation camps held in the blood bank and outdoor camps from August 2014 to August 2015 were analyzed retrospectively. Based on the history and physical examination findings; all blood donors coming for the donation were classified into fit for donation or deferred donor. Results: A total of 24,062 subjects registered for donation during the study period (August 2014 to August 2015) out of which 4125 were deferred prior to donation. The incidence of deferral was 17.1%. Most common reasons for deferral were anemia (2107 out of 4125) accounting for 51% of deferred donors, abnormal blood pressure 6.8% (281/4125), and history of medication 18% (743/4125). Majority of them were temporary deferrals 86.1% (3822/4443). Permanent deferral accounted for 13.9% (621/4443). Most of these deferred donors were aged between 18 and 30 years old. Most common reason for deferral in males and females both was anemia with an incidence of 32.7% (900/2750) and 87.7% (1207/1375) in males and females, respectively. Discussion and Conclusion: Insight into the reasons of donor deferral is very important to avoid the permanent loss of the donor as blood donation program is the life force behind any blood bank or hospital. Deferral study also indicates the health status of the general population. Since most of the deferrals are temporary deferrals, and we should give a clear message for the reason for deferral, so that they return for donation in the future.
