Abstract
Background:Blood transfusion is a life-sustaining procedure in several medical and surgicalconditions. Blood safety is a major issue world-wide in transfusion medicine.Donor selection criteriaare essential in blood donation assessment, prioritizing both recipient and donor safety.Temporarycauses for deferral should be counseled while permanent causes deferred for a life time. It is importanttoanalyzethe varied reasons of deferrals in order to lessen the deferrals in the future.
OBJECTIVES: 1.Toanalyzeand categorize the reasons for donor deferral among blood donors (temporary / permanent) 2.To implement possible recommendations for reducing preventable donordeferrals among blood donors
Methods:Retrospective analysis was done in blood center, tertiary care hospital from April 2023 toMarch 2025. Sample size is calculated by universal sampling. Data was collected from the blooddonor’sstandard questionnaire forms and rejection register. Criteria for donor rejection was followedwith Drug and Cosmetics act 1940, last amended March 2020. Rate of rejection= Number of deferral/Total number of donors x 100. Statistical analysis wasdone bydescriptive analysis.
Results:A total of 4937 blood donors were registered during the study period in which 4590(92.96%)were males and 357(7.23%) were females. A total of 217(4.39%) donors were deferred due to variousreasons. Among these, 206(94.93%) were temporary and 11(5.07%) werepermanent deferrals. Themain reason for temporary deferral is recent alcohol intake 42(20.39%), high blood pressure25(12.14%) and low hemoglobin 24(11.65%); while for permanent deferral was cardiac disease3(27.27%),hypothyroidism 3(27.27%), and uncontrolled diabetes 3(27.27%). The donor deferral ratein our study is 4.3%.
Conclusion:Blood donor deferrals lead to loss of precious blood/blood components available fortransfusion in emergency situation. To avoid such problems, we should be aware about its reasonsand frequency. To improve donor eligibility and retention, targeted strategies including enhanced education and community engagement with pre donation awareness programs are essential to
strengthen blood transfusion services.
