Summary
A new pre-donation interview questionnaire significantly improved the identification of blood donors at risk for viral transmission. This enhanced screening process led to a higher exclusion rate, particularly for behaviors linked to sexual activity and partners.
Area of Science:
- Transfusion Medicine
- Epidemiology
- Public Health
Context:
- Clinical selection of blood donors is crucial for preventing viral transmission via transfusion.
- Previous screening methods may not adequately identify all at-risk individuals.
- The study was conducted in five blood banks in the French Ile-de-France region.
Purpose:
- To evaluate the effectiveness of a newly developed questionnaire for pre-donation medical interviews.
- To assess the questionnaire's ability to identify risk behaviors in blood donors and their partners.
- To compare exclusion rates and reasons with a previous study.
Summary:
- A new questionnaire focusing on risk behaviors was implemented and evaluated in 1,527 blood donation volunteers.
- The study observed a significant increase in donor exclusions due to risk behaviors (3.7% vs. 1.5%) and medical reasons (12.2% vs. 8.4%) compared to a 1993 study.
- Exclusions related to sexual risk behaviors, including male homosexuality and partner's behavior, rose substantially from 12% to 35%.
Impact:
- The new questionnaire demonstrated value in enhancing the clinical selection of blood donors.
- The findings highlight the importance of targeted screening for risk behaviors to improve blood safety.
- The study provides evidence for refining donor selection protocols to minimize transfusion-transmitted infections.
