Pre-donation deferral of blood donors in South Indian set-up: An analysis

Abstract

Background:It is well known that quite a large number of apparently healthy donors are not able to donate blood successfully because of varied reasons.Aim:We want to analyze the rate and various reasons for deferrals.Materials and Methods:A retrospective analysis of records of the donors, for 3 years, from January 2005 to December 2007 was done, in order to find out the rate and causes of deferral in four categories of age groups, both in male and female, in our Transfusion Medicine Centre, Bangalore, India.Result:There were 16,706 donors, of which 976 donors were deferred (5.84%) for various reasons. Of the 16,706 donors registered for donation, females constituted only 11.27%. And deferral rate was about five times more for female (19.85%) compared to male (4.06%). The three most common reasons for deferral in female were low hemoglobin levels, low body weight, and hypotension. The deferral rate was higher in the age group of 18-25 years and most common cause was low hemoglobin level. In male, the three most common reasons for deferral were hypertension, under weight, and low hemoglobin levels. The deferral rate varied from 4 to 15% as reported in the literature. The most common cause of deferral in our study and in several studies available in the literature is the same.

Analysis of Pre-Donation Deferral Causes in Blood Donors at a Rural Medical Institute of Rohilkhand Region, India

“…Males outnumbered females almost twenty times. Preponderance of male blood donors has also been reported by several other authors [5][6][7][8][9][10][11][12][13][14][15]. Alfouzan [16] in his study reported high blood donation attitude score and significantly higher blood donation knowledge in males than females, which could be the probable reason of male preponderance in our study.…”

“…Most of the donors deferred in this study were in the age group 18-30 years (55.5%). Almost similar age related demographic profile was described in the studies under taken by other authors [5][6][7][8][9][10][11].…”

“…Higher rates of deferral were reported by Agnihotri [7] (11.6%) from Western India and Arun et al [8] (11.6%) from Tirupati. Much lower rates of deferral were reported by Kumar et al [9] (2.50%) from Jagdalpur and Patil et al [10] (3.95%) from Solapur. Most of the donors deferred in this study were in the age group 18-30 years (55.5%).…”

Evaluation of blood donor deferral causes in a tertiary hospital, South India

“…Several studies have reported a similar deferral rate (5.20%) by Unnikrishnan et al [3], (6%) by Sundar et al [4], and (5.6%) by Rabeya et al [5]. Some studies have even had a higher deferral rate of (16.4%) Chaudhary et al [6], (35.6%) Charles et al [7].…”

“…The deferred 858 cases were categorized into temporary constituting (58.04%) with 95% CI: 54.66%-61.37% and permanent (41.96%) with 95% CI: 38.63%-45.34% in (Table 3, 4,5). Among the 498 temporarily deferral cases, anemia was the number one cause of deferral constituting (15.66%), followed by medications (11.65%), fever (9.44%) as shown in (Table3).…”
