Insights

Implementing malaria nucleic acid testing (NAT) could ease blood donation deferrals for diverse communities. Clear communication is vital, as participants expressed concern about potential positive malaria NAT results.

Area of Science:

  • Public health
  • Blood donation policy
  • Infectious disease screening

Background:

  • Blood collection agencies (BCAs) aim to increase donor diversity.
  • Current malaria deferral criteria create barriers for some communities, particularly African, Caribbean, and Black (ACB) communities.
  • Implementing malaria nucleic acid testing (NAT) could allow for easing deferral criteria.

Purpose of the Study:

  • To explore public views on potential changes to malaria deferral criteria in blood donation.
  • To understand donor perspectives on screening processes and potential malaria NAT implementation.

Main Methods:

  • A mixed-methods, community-based study was conducted in Canada.
  • Qualitative component involved semi-structured interviews with 26 participants.
  • Topics included donation experiences, knowledge of deferral criteria, and responses to potential positive malaria NAT results.

Main Results:

  • Participants viewed blood safety as a shared responsibility.
  • Most participants were comfortable with screening questions.
  • A positive malaria NAT result could elicit concern, fear, and uncertainty.

Conclusions:

  • Clear and effective communication is essential if BCAs implement malaria NAT and ease deferral criteria.
  • Focus communication efforts on impacted communities.
  • Collaboration with community partners is recommended for effective communication.
