HOSPITAL COSTS ASSOCIATED WITH AGRICULTURAL MACHINERY INJURIES IN ONTARIO

To assist those responsible for agricultural safety, we: (1) piloted a n approach to costing hospitalized farm injuries; and, (2) described a mbulance and inpatient costs associated with these injuries in Ontario . Hospital discharge records (hospital separations) for farm machinery injuries in Ontario (n = 1,610) were identified by ICD9-CM E-codes fo r 1985-1993. Ambulance costs were estimated by the Ontario Ministry of Health. For each case, the hospital costs were calculated by multiply ing the case-specific resource intensity weight by the average inpatie nt cost per weighted case. The costs (1993 Canadian dollars) ranged fr om $768 to $62,643 and totaled $6.9 million over the study period. Mal es accounted for 89.8% of the total costs. Tractor injuries accounted for a large proportion of costs (34.3%). The median costs per case var ied by type of machinery, ranging from $2,043 for ploughs/disks to $3, 366 for augers. Entanglement injuries were responsible for the largest proportion of costs (40.7%), while tractor rollovers accounted for th e highest median cost ($3,065), Although these figures represent a fra ction of the total costs associated with farm injuries, the results pr ovide one basis from which to justify and target preventive initiative s. This approach to costing may also be widely, applicable to other he alth issues. (C) 1997 Wiley-Liss, Inc.
