A computerized procedure used to assess exposure information for an epidemiologic survey of health outcomes in acrylonitrile (107131) exposed workers was discussed. The technique was developed to systematically organize and document narrative information on job histories and exposures obtained for approximately 27,000 workers exposed to acrylonitrile in eight factories producing or using acrylonitrile from the 1950s through 1983. The procedure utilized a computerized data management system with job exposure profiles (JEPs) and department exposure profiles (DEPs) which stored exposure and other job related information that might be needed to develop quantitative exposure estimates for each and department. The DEPs contained information that was common to all jobs within each department such as process description and production rates. The JEPs contained information specific to each job such as frequency of exposure and frequency of peak exposure. An interactive data entry and access system linking the DEP and JEP fields was also developed so that any item inputted into a DEP would be included in the associated JEPs. Several quality control and internal logic and range checks and edit reports were incorporated into the system. A users manual was developed which described in a step by step fashion the use of the JEP system. The authors note that the advantage of having a computerized system such as this is that it organizes and documents in an efficient way the large amounts of data collected in industry based epidemiological surveys.
