Background: Distal radius fractures are the most common fracture of childhood, occurring in approximately 1 per 100 children annually. Given the high incidence of these fractures, we explored feasibility of a bundled payment model. We determined the total treatment costs for each child and identified components of fracture management that contributed to variations in cost.
Methods:We retrospectively reviewed all hospital and physician costs related to the treatment of closed distal radius fractures at a large academic children's hospital. We included all children age 2-15 years treated by an orthopaedic surgeon for an isolated closed distal radius fracture between 2013 and 2015. We compared total treatment costs by fracture management approach. We then estimated the contribution of each component of fracture management to total treatment costs using linear regression.
Results:We identified 5,640 children meeting the inclusion criteria, of which 4,602 (81.6%) received closed treatment without manipulation, 922 (16.3%) underwent closed reduction in the clinic, emergency department, or radiology procedure suite, and 116 (2.1%) underwent treatment in the operating room. The median cost for closed treatment without manipulation was $1,390 (IQR 1,029-1,801), compared to $4,263 (IQR 3,832) for closed reduction and $9,389 (IQR 8,119) for closed reduction and percutaneous pinning (p<0.001). In multivariable regression analysis, fracture management approach and use of the operating room environment were the largest cost drivers (p<0.001, R 2 =0.88).
