Objective: To describe the spectrum of work-related injury evaluated in a rural ED population.
Methods: An ED-based injury surveillance system (EDBISS) was used to collect injury data for all ED patients seen over a 1-year period. A patient was classified as injured if his or her record contained an ED log injury code, an ICD-9 N-code between 800 and 995 in any diagnostic field, an E-code, or an entry in the trauma registry. An injury was considered work-related if the patient reported that the injury had occurred while at work.
Results: Work-related injuries accounted for 1,539/12,321 (12.5%) of all injuries. The mean age of patients injured on the job was 33.8 years (range, 16-77 years), compared with a mean age of 27.7 years for all the injured patients. Males accounted for 1,026/1,537 (67%) of the work-related injury visits, compared with 57% of all the injury visits. The most common mechanisms of work-related injuries were: overexertion (313; 20%); cut or pierced by sharp implements (248; 16%); falls (250; 16%); struck by object (202; 13%); and transportation-related injuries (71; 5%). Sprains and strains were the most common type of injury sustained (415; 27%), followed by wounds to upper limbs (283; 18%), contusions (182; 12%), and fractures (151; 10%). Of the 1,539 patients presenting with occupational injuries, 178 (12%) presented to the ED via ambulance. Most (1,401; 91%) were treated and released from the ED, with the remainder (136; 9%) hospitalized. The mechanisms of injury that most commonly resulted in hospitalization included struck by an object (28; 21%), transportation (26; 19%), falls (27; 20%), crushing mechanism (13; 10%), and machinery (20; 15%). Of those requiring hospitalization, 132/136 (97)% were male, and the average length of stay was 4.4 days. Four of the hospitalized persons died of their work-related injuries. Known medical charges incurred by patients injured at work were as high as $62,622. The average charge for those treated and released was $273; the average charge for those who required hospitalization was $10,910.
Conclusions: Occupational injuries contribute significantly to the overall incidence of injuries seen in this ED and are responsible for significant medical charges each year.
