    Summary

    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.
