Background: A  screening  procedure  is  mandatory  before  blood  donation  to  ensure safety  of  blood  donors  and  recipients. This  process  can  lead  to  deferral  of  blood  donors due  to  temporary  or  permanent  reasons  and  eventually  shortage  of  blood  unit  or  donor pool. By  analysing  the  donor  deferral  pattern  and  motivating  them, donor  pool  may  be recruited  in  future  for  further  blood  donation.

Objective : To  study  the  deferral  rate  and  different  causes  of  donor  deferral  in  a  newly established  blood  bank  of  a  tertiary  set  up  in  South  Delhi.

Methods: It  is  a  retrospective  study  conducted  at  Hamdard  Institute  of Medical  Sciences  and  Research (HIMSR)  over  a  period  of  7 years (2012-2018)  since  the inception  of  its  new  blood  bank  in  2012. All  the  donors  were  screened  in  accordance with  the  National  guidelines. Data  was  analysed  with  respect  to  their  age,  sex,  type  of donors, type  of  deferral  and  reasons  for  deferral.

Results: A  total  of  7806  donors  were  registered (7503 Males, 303 Females)  during  the study  period, out  of  which  988 (12.6%) donors  were  deferred. Amongst  deferred  donors, males (81.6%)  outnumbered  the  females (18.31%). Overall  deferral  percentage  was  12.6% which  was  more  common  in  females (59.7%)  as  compared  to  males (10.7%). Most  common cause  of  deferral  in  our  study  was  Anaemia (43.2%)  followed  by  Alcoholism (13%)  and Hypertension (10%).

Conclusions: Studying the pattern of blood donor deferrals and its causes will help in identifying the donor population which could be targeted to increase the donor pool by participation in voluntary blood donations.
