Replacement donors pose a higher risk for transfusion-transmissible diseases. However, targeting repeat replacement donors for blood donation offers an acceptable risk profile, enhancing the donor pool.

Area of Science:

  • Transfusion Medicine
  • Blood Donor Selection
  • Public Health

Background:

  • Replacement donors exhibit higher rates of transfusion-transmissible disease markers compared to volunteer donors.
  • Efforts are underway to identify safer subgroups within the replacement donor pool for routine donations.

Purpose of the Study:

  • To evaluate the safety and efficacy of a replacement donation program.
  • To identify a safer subgroup of replacement donors for routine blood donations.

Main Methods:

  • Retrospective review and cohort study design.
  • Separation of replacement-donor and new-donor effects.
  • Quantification of risks associated with transfusion-transmissible diseases, donor retention, and donation frequency.

Main Results:

  • Replacement donors showed 3.1 times the risk of transfusion-transmissible diseases compared to repeat volunteer donors.
  • Donor retention rates (0.72) and returning donation frequency (0.81) were lower for replacement donors.
  • Targeting repeat replacement donors yielded risk profiles comparable to general volunteer donors.

Conclusions:

  • The negative impact of replacement donors is comparable to that of new volunteer donors.
  • A replacement donation program focused on repeat replacement donors presents an acceptable risk profile.
  • Such programs can serve as a valuable supplement to existing volunteer blood collection efforts.
