Abstract
Introduction: -Accessibility of a safe and adequate blood transfusion is a challenge worldwide
and even more critical in sub Saharan Africa. 44 % of maternal deaths due to blood loss during
child birth, 20% of maternal and 15 % of child death as a result of anemia in Africa region could
be managed with a well-timed safe blood transfusion. Though the world health organization
(WHO) recommends that blood donation by 2%-3% of the country’s population is needed to
meet a nation’s most basic requirement for blood, in Ethiopia less than 0.5 % of the population
donates blood and nationally there are only 10,000 regular blood donors.
Objective:-The aim of this study was to evaluate the return rate and return determinants among
first time voluntary blood donors in Ethiopian national blood bank service (ENBBS).
Methods:-To determine first time voluntary blood donors return rate secondary data reviewing
was done. To investigate return determinants facility based unmatched case control study design
was implemented. The cases were first time voluntary blood donors returned for donation within
two years since their index donation whereas controls were those who didn’t return. Pretested
questionnaire was used to guide a telephonic interview to collect data from 438 samples that
were selected randomly from the Ethiopian national blood bank service (ENBBS) donor record
server. Filled data was pre coded and entered in Epidata version 3.1 and was exported to STATA
version 14 for cleaning and analysis. Descriptive summary measures were used to describe levels
of exposure in cases and controls and to assess the presence of association and their significance
level a bivariate and multivariate logistic regression analysis were used.
Result:-Reviewing 24,684 first time voluntary blood donor’s record the return rate was found to
be 37.7% per two years. First time voluntary blood donor return was found more likely to be
determined by altruism as a motivational factor for an index donation (AOR=1.96, 95% CI: 1.02-
3.64) , positive perceived donation capability (AOR=7.3, 95% CI: 2.9 -15.04), Being aware of
previously donated blood volume (AOR=4.8, 95% CI: 2.18 - 8.98).
Conclusion:-Return rate of first time voluntary blood donors in ENBBS was low and return for
subsequent donation was found more likely to be determined by donor's altruistic behavior,
positive perceived capability and awareness on blood donation process. Therefore working on
VII
donor’s awareness on the donation process and promoting encouraging message on building up
altruistic motivation could enhance the return of first time voluntary blood donors.
