A state trauma registry as a tool for occupational injury surveillance.
The goal of occupational surveillance is to identify and determine the magnitude of work-related disease and injury and workplace hazards for the purposes of focusing prevention programs and tracking their effectiveness. There are a number of databases that collect information on pieces of the puzzle of workplace exposure and adverse health outcomes. Other than that for the fatalities, none of these datasets specifically describes the most severe occupational injuries or their attendant disability. The goal of this study was to evaluate the usefulness of the Illinois Trauma Registry (ITR) in the surveillance of occupational injuries. The entire dataset of the ITR was obtained from the Illinois Department of Public Health for the years 1993 and 1994. The occupational injuries were extracted and frequency distributions were determined for all demographic and health variables. Background population, employment, and death-rate data were obtained for the purpose of rate calculation and for comparison of raw data. Mean costs for acute occupational injuries were calculated. There were 5844 occupational cases, comprising 6.7% of the total group. The majority of injuries had occurred in males (86%), in urban settings (81%), and were of the "blunt" injury type. External cause (coded according to the International Classification of Diseases, 9th Revision, External Injury) categories for work-related injuries were "Cut/Struck," 39%; "Falls," 36%; "Transportation," 12%; "Environmental," 6%; "Violence," 3%; and the remainder, 5%. By definition, all cases were admitted to the hospital, with 62% classified as "minor," 28% "moderate," and the remaining 11% "severe" to "life threatening." Surgery was performed in 54%, and admission to a monitored bed or the intensive care unit occurred in 15%. Although 93% were discharged home, only 54% ambulated independently. Seven percent were not independent with regard to self-feeding status. The mean hospital charge was $10,802 (standard deviation, $31,438). A pyramidal model of the place of ITR cases in the universe of occupational injuries is presented. The ITR contains a unique set of variables that broaden our understanding of serious work-related injuries. It is recommended that these variables--"occupation," "type of industry," and "nature of injury"--be added to the ITR so that it may be linked with other databases to check its validity and completeness and to enhance its value in occupational surveillance.
