BACKGROUND: In current medical and surgical practice blood transfusion is a vital and life-saving procedure, for which we require an adequate safe supply of blood from healthy donors. Blood donors are generally perceived to be healthy, but some donors may be unfit or unsuitable for donating blood. So, it is the responsibility of the blood transfusion team to identify those unsuitable donors and defer them as appropriate either temporarily or permanently. However making an unnecessary donor deferral, especially temporary deferment may lead to loss of potential blood donors, whom later may be reluctant to return for donating blood in future.

AIM: To assess the incidence and the factors related to blood donor deferrals at a tertiary care hospital in South India.

METHODOLOGY: A retrospective study was carried out in the blood bank of Vinayaka Missions Hospital, Salem during the period January 2012 to December 2013, by using the blood bank registers. A total of 5641 were registered during that period. Each and every donor were evaluated on the basis of a medical history, physical examination, haemoglobin estimation, weight, age, blood pressure, pulse rate, temperature and screening for all infectious diseases. Details of all those who were deferred were recorded in the deferral register along with the reason for deferral.

RESULTS: Of the total population of 5614 only 94 subjects were deferred from donating the blood, which shows the incidence of deferral population to be 1.6%. Deferrals among the study subjects were classified as temporary and permanent deferrals. Among the 94 subjects who were deferred from donating blood, 76 were graded as temporary deferrals and 18 were permanent deferrals. Anemia is the most common cause for temporary deferrals and HBV positive subjects were the commonest cause for permanent deferrals.

CONCLUSION: The knowledge of the deferral incidence and its causes in a particular region would help in estimating the eligible and the prospective donor potential for which the regional blood centres would play a vital role. Hence, common “Donor Deferral Registers” may be valuable at the local and the regional levels.
