title: Cost effectiveness of a dealer's intervention in retrofitting rollover protective structures.
abstract: OBJECTIVE
  To evaluate the cost effectiveness of a 4.5 year education campaign that promoted farmers' adoption of rollover protective structures (ROPS) to prevent tractor overturn injuries.
  
  
  METHODS
  Randomized controlled trial, decision analysis, and cost effectiveness analysis.
  
  
  METHODS
  One treatment county and one control county in the State of Kentucky.
  
  
  METHODS
  A campaign by a local tractor and equipment dealership to encourage farmers to purchase and install ROPS and seatbelt retrofit kits for older tractors.
  
  
  METHODS
  Number of injuries averted and cost per injury averted.
  
  
  RESULTS
  The dealership's 4.5 year intervention was shown to potentially reduce both fatal (0.26) and non-fatal (1.50) injuries by 2.6% in its county over the intervention period using a 20 year analytic horizon. When extrapolated statewide, 6.7 lives would be saved and 39 non-fatal injuries would be averted over the combined 24.5 year combined intervention period and analytic horizon. The intervention for this period was cost effective with a "savings" of 35,713 dollars per injury (fatal plus non-fatal) averted at a 4% discount rate.
  
  
  CONCLUSIONS
  Tractor manufacturer promotions can influence their dealerships to promote ROPS retrofits by their customers. A manufacturer backed dealer ROPS retrofit campaign was cost effective in reducing overturn related injuries.
