Questionnaire Data for Risk Assessment Presented by: Richard Forshee FDA/CBER/OBE
Donor Questionnaire Issues At least 2 purposes of DHQ –Protect the health of the donor –Identify risk factors to protect the health of recipients Understanding how donors respond to the questionnaire –Complexity of questions varies –Some questions involve personal and sensitive subjects Use of DHQ in risk assessment
Use in Risk Assessment Does the questionnaire accurately identify donors with selected risk factors? –Travel to malarial areas Are low-risk donors being deferred because of answers to the questionnaire? –Travel to malarial areas
Hypothetical Example Later in this workshop we will be considering a hypothetical outbreak of a viral hemorrhagic fever caused by an RNA virus in 3 Midwest US states We have constructed an extremely simplified risk assessment to predict the cases of transfusion transmitted hemorrhagic fever Imagine two different DHQ methods of assessing the risk that a donor is infected with the hemorrhagic fever
