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.
