Evaluation of blood donor deferral causes: a tertiary-care center-based study

Abstract

According to the figures of World Health Organization (WHO), over 81 million units of blood are collected annually worldwide, but only 39% are collected in developing countries, which have 82% of the world's population. [2] A blood bank plays an important role in ensuring the supply of safe blood as and when required. Although it is important to ensure that there is an adequate supply of blood, it is also essential that the blood collection process does not harm either the donor or the recipient. This is achieved by having donor deferral criteria [3] and stringent screening of collected blood for possible transfusion transmissible infections (TTIs). [4] Deferrals are divided into permanent and temporary. Few studies conducted in India in the past have provided different common reasons for deferral of whole blood donors, highlighting differing demographic profile in different parts of the country. [5,6] The aim of our study was to know the profile of the blood donors and causes of the permanent and temporary deferral and their frequency. This prospective study was conducted in the blood bank of C.U.

Retrospective analysis of blood donor deferral pattern at a tertiary Care Centre

“…The donor deferral population was categorized into temporary and permanent deferrals. Among the deferrals, temporary causes (76.19%) were more common as compared to permanent causes (23.81%).The most common cause of temporary deferral in both males and females was anemia (46.5%) in our study which was similar with other previous studies [15,16] . This supports the fact that the prevalence of clinical and subclinical anemia is very high in developing countries like India.…”

Prevalence of anemia in blood donors: a retrospective study in rural tertiary care centre (Chamba, Himachal Pradesh, India)

“…of male deferrals were much higher (72%) than female donors (21.73%). 11,12 It was observed in our study that prevalence of anemia is 2.3% in total blood donors (Table 3). Similar findings were shown by Bahadur et al and Kumari et al, who reported 1.8 % and 1.7% anemia, respectively in their studies.…”

Causes of deferrals during blood donation on healthy people of Gurugram: A crossectional study

“…Previous studies, as well as the present study, reveal that the most common cause of deferral is due to low hemoglobin concentration or anemia followed by low BP, animal bite, typhoid, menstrual cycle, body tattoo, underweight, antibiotic, thin vein, fast bleeding, and chikungunya. Anemia occurs due to improper dietary source and intake of junk food and snacks that lead to decreased nutrition level [10][11][12] were due to low hemoglobin concentration or anemia 13 . Anemia can be cured by taking proper treatment with regular checkups and awareness of dietary sources.…”
