Subjective donor deferral as a tool for increased blood transfusion safety: A cross-sectional observational study.

Objectives: This study aims at evaluating whether subjective donor deferral (SDD) has the potential for increasing blood transfusion safety.

Background: Appropriate donor selection via clinical and serologic screening is necessary to prevent transfusion-transmissible infections (TTIs). One additional strategy adopted by some Brazilian blood transfusion centers (BTCs) is the rejection of a donation by the pre-donation interviewer based on subjective factors.
