Recruiting lapsed blood donors, even those who haven't donated in over five years, can increase blood supply safely. These repeat donors show lower viral infection rates compared to first-time donors.

Area of Science:

  • Blood Transfusion Medicine
  • Public Health
  • Epidemiology

Background:

  • Ensuring blood supply safety is critical, necessitating effective donor recruitment and retention strategies.
  • Previous research indicates lower viral prevalence in repeat donors versus first-time donors.
  • The impact of extended donation lapses on viral marker prevalence remains understudied.

Purpose of the Study:

  • To investigate the relationship between donation history, lapsed interval length, and viral marker prevalence (HCV, HIV, HBsAg).
  • To determine if repeat donors with long donation lapses maintain lower viral prevalence rates compared to first-time donors.
  • To explore demographic factors influencing donor return behavior.

Main Methods:

  • Analysis of 6.4 million allogeneic donations from five US blood centers (1991-1998).

Related Experiment Videos

  • Classification of donations by donor history (first-time vs. repeat) and lapsed interval length.
  • Comparison of viral marker prevalence (HCV, HIV, HBsAg) across donation categories and demographic groups.

    • Main Results:

    • Repeat donors with donation lapses exceeding five years exhibited significantly lower viral infection rates than first-time donors.
    • Viral marker prevalence increased with lapsed interval length for HCV and HBsAg, but not HIV.
    • Younger, less educated, and nonwhite donors were less likely to return for donations.

    Conclusions:

    • Targeting lapsed donors, particularly those with extended intervals, presents a viable strategy to safely expand the blood supply.
    • Understanding donor demographics is crucial for developing effective recruitment and retention programs for blood donation.
    • Lapsed donors can contribute to blood safety and supply without compromising screening protocols.
