Epidemiologists carrying out retrospective evaluation of occupational
exposure to solvents often use experts to assist in drawing up and
interpreting structured questionnaires. However the epidemiologist cannot
pass complete responsibility to the expert for deciding on the relative
importance of the different exposure variables. Expert assessment of
exposure to organic solvents was carried out in a population-based
case-control study. The process of expert evaluation was examined and the
different steps in the process identified. This paper describes work in
progress on the formalization of the rules that experts use to identify and
quantify exposure.
