Area of Science:

  • Transfusion Medicine
  • Geriatric Medicine
  • Public Health

Background:

  • Many countries impose upper age limits for blood donation.
  • The safety of whole blood donation in elderly populations requires evaluation.

Purpose of the Study:

  • To assess the safety of whole blood donation in elderly Canadian allogeneic donors.
  • To analyze reaction rates in relation to age and donation frequency.

Main Methods:

  • Retrospective analysis of reaction rates in allogeneic whole blood donors at Canadian Blood Services.
  • Data stratified by age, donation frequency, and age-specific donation frequency.

Main Results:

  • The highest rate of mild reactions was observed in donors under 20 years old.
  • Moderate and severe reaction rates decreased with increasing age and donation frequency.
  • Age-adjusted rates for mild, moderate, and severe reactions were low in donors aged 60-71 years, especially with higher donation frequencies.

Conclusions:

  • Whole blood donation is safe for regular donors aged 66-71 years.
  • Current upper age limits for blood donation may not be necessary based on safety data.
