A Retrospective Analysis of Apheresis Donor Deferral and Adverse Reactions at a Tertiary Care Centre in India

Abstract

Introduction: With increasing demand of platelet component each day, blood bank plays a pivotal role in ensuring supply of safe blood as and when required. Plateletpheresis procedure is a relatively simple, safe and important adjunct to blood bank inventory. However, recruitment of healthy blood donors is a challenge that the health industry is facing today. Aim: To determine the reasons and rates of apheresis donor deferral along with investigation of adverse reactions encountered during the procedure. Materials and Methods: Records of single donor apheresis were retrospectively analysed from 1st January 2010 to 31st December 2014. The study was carried out at Blood Bank, Safdarjung Hospital, New Delhi, India. The donor details that were studied included – age, sex, type of donation (voluntary/ replacement/ repeat), reason for donor deferral and type of adverse reaction, if encountered during the procedure. Results: Among the 478 donors screened for plateletpheresis procedure during a study period of 5 years, 134 (28.03%) were deferred. Temporary deferrals accounted for majority (93.28%) of the deferrals. Low platelet count (50.75%) was the main reason of donor deferral followed by low haemoglobin (20.89%). Amongst the 344 selected donors, 15 (4.36%) had some type of adverse reaction associated with the procedure. Conclusion: We suggest that the selection criteria for plateletpheresis donors should be revised to deal with shortage of apheresis donors. The criteria regarding minimum preprocedure platelet count (above1.5 lac/μl) and haemoglobin (above 12.5 g/dl) need to be lowered so as to suit the Indian scenario. The lower adverse reaction rates, 14/344 (4.06%) associated with this procedure encourages safety of donors and is important in recruitment of new donors.
