Insights
French blood centers screened donors for AIDS risk factors since 1984. Direct questioning proved difficult for whole blood donors but effective for cytapheresis and plasmapheresis, relying on self-exclusion due to lack of markers.
Area of Science:
- Transfusion Medicine
- Infectious Disease Prevention
- Public Health Policy
Background:
- The study addresses the critical need for safety measures in blood donation to prevent the transmission of Acquired Immunodeficiency Syndrome (AIDS).
- It examines the period starting January 1984, a crucial time in understanding and combating HIV transmission.
- French Blood Centers were surveyed to understand their screening protocols.
Purpose of the Study:
- To determine the specific measures implemented by French Blood Centers to prevent AIDS transmission via blood donations since January 1984.
- To evaluate the effectiveness and challenges of different donor screening methods in the absence of a biological marker for HIV.
Main Methods:
- Analysis of responses from 49% of French Blood Centers, representing 75% of national blood collection.
- Review of screening procedures, focusing on information provided to donors and direct questioning regarding risk factors.
- Comparison of screening methods for whole blood donors versus cytapheresis and plasmapheresis donors.
Main Results:
- In the absence of a biological marker, screening relied primarily on informing unpaid blood donors to encourage spontaneous self-exclusion.
- Direct questioning of donors about risk factors presented significant challenges for whole blood donations.
- This direct questioning method was more successfully implemented during cytapheresis and plasmapheresis due to enhanced interaction between donors and medical staff.
Conclusions:
- The primary strategy employed by French Blood Centers to mitigate AIDS transmission through blood was donor education and self-exclusion.
- Direct risk factor questioning, while problematic for whole blood donation, showed promise in apheresis procedures.
- Further development of screening strategies was necessitated by the lack of early diagnostic markers for HIV.
Abstract:
Following an inquiry to determine what measures has been taken since january 1984 in French Blood Centers to avoid transmission of AIDS by blood, answers from 49 % of the centers, representing 75 % of the blood collection in France were analyzed. Due to the absence of a biological marker, only information given to blood donors, unpaid in France, permitting spontaneous autoexclusion had been used to screen donors in blood center. Direct questioning of donor for risk factors before taking blood raised numerous problems in donors of whole blood, but could be satisfactorily implemented in cytapheresis and plasmapheresis donors mainly because of closer human contact between volunteers and the medical staff.
