Implications for the use of E codes of the International Classification of Diseases and narrative data in identifying tractor-related deaths in agriculture, United States, 1980-1986.
Scand J Work, Environ & Health 1992 Jun; 18(Suppl 2):49-50
This study examined the E-coding of the International Classification of Diseases, ninth revision (ICD-9), for accidental deaths in an attempt to determine the usefulness of this code. The National Traumatic Occupational Fatalities (NTOF) surveillance system data were reviewed for deaths in the agriculture, forestry and fishing industry which involved a tractor using a key word search. Tractors were recorded in death certificates as being involved in 1349 (25%) occupational injury fatalities in the agricultural, forestry and fishing industries from the years 1980 to 1986 in the US. An average of 193 tractor related deaths occurred each of these years. The victims were farmers in 89% of the cases and males in 99%. There were 1349 events, of which 84% were coded to the ICD-9 rubric E919.0, agriculture machinery related accidents. Motor vehicle traffic categories accounted for another 10%. The others were coded to other E-code rubrics, including struck by falling object and motor vehicle nontraffic. Of the 1349 total deaths, 48% were attributed to tractor rollovers, and 13% to run over incidents, with a power takeoff shaft or drive being mentioned in 2%. The authors conclude that the availability of automated narrative data in the NTOF surveillance system provides the opportunity for key word and manual searches to identify problems more specifically than the number coded data allow. The use of such narratives provides enough detail to allow researchers to begin to assess possibilities for prevention.
