ABSTRACT
BACKGROUND:
To convert first-time blood donors into regular volunteer donors is a challenge to transfusion services.OBJECTIVES:
This study aims to estimate the return rate of first time donors of the Ribeirão Preto Blood Center and of other blood centers in its coverage region.METHODS:
The histories of 115,553 volunteer donors between 1996 and 2005 were analyzed. Statistical analysis was based on a parametric long-term survival model that allows an estimation of the proportion of donors who never return for further donations.RESULTS:
Only 40 percent of individuals return within one year after the first donation and 53 percent return within two years. It is estimated that 30 percent never return to donate. Higher return rates were observed among Black donors. No significant difference was found in non-return rates regarding gender, blood type, Rh blood group and blood collection unit.CONCLUSIONS:
The low percentage of first-time donors who return for further blood donation reinforces the need for marketing actions and strategies aimed at increasing the return rates.
