Abstract
Blood safety is a major issue all over the world in transfusion medicine. For this, donor selection is necessary in addition to the screenings of blood bags for infectious diseases. Deferrals lead to loss of precious blood/ components available for transfusion. For preventing this, we should be having knowledge of causes of deferral and their frequency. In this study, causes of donor deferral were evaluated retrospectively from January 2007 to December 2011 in the blood bank of Jawaharlal Nehru Medical College (JNMC), Aligarh Muslim University (AMU), ALIGARH (India). Analysis of the deferrals showed that temporary deferral was more common than permanent deferral. Most common cause in permanent deferral was HBsAg positivity. Causes among temporary deferral were anemia (Hb<12.5 gm%), malaria in last 3 months, jaundice, alcohol intake in last 3days, weight <45 kg, age <18 yrs, patients on antibiotic, previous donation in last 3 month, typhoid in last 1 year, dog bite etc.
Highlights
In current medical and surgical practice, a blood transfusion can be a vital, life-saving procedure
Rabeya et al [11] found a very low deferral rate in their study (5.6%) which could be due to different donor selection criteria
The present study showed that donor deferral rates were very much similar in different populations, the reasons for deferral differ, reflecting difference in socioeconomic status and environment
Summary
In current medical and surgical practice, a blood transfusion can be a vital, life-saving procedure It requires an adequate supply of safe blood from a healthy donor. While it is important to ensure that there is an adequate supply of blood, it is 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]. The aim of our study is to know the profile of the blood donors and causes of the permanent and temporary deferral and their frequency This retrospective study was conducted in the blood bank of JNMC, AMU, Aligarh (India) from January 2007 to December 2011
