Objectives:
We hypothesized that negligible surgical material cost variation exists between traumatolgists for treatment of bimalleolar ankle and bicondylar tibial plateau fractures.
Design:
Retrospective medical record review.
Setting:
Academic level 1 Trauma Center; 2-year period.
Patients/Participants:
Current Procedure Terminology codes for open treatment of bimalleolar ankle and bicondylar tibial plateau fractures identified patients. Patients who had operative treatment of other injuries under the same anesthetic session were excluded. Only definitive treatment procedures were analyzed.
Intervention:
We analyzed the intraoperative material costs of these procedures and compared them between surgeons. This analysis was done with a newly developed proprietary program designed for inventory and cost analysis.
Main Outcome Measurements:
Mean and median total case material costs were compared using one-way analysis of variance. Individual items that significantly increased costs were identified.
Results:
We identified 88 bimalleolar ankle and 46 bicondylar tibial plateau fractures treated by 6 surgeons. The mean intraoperative material cost per bimalleolar ankle fracture was $1099. The least expensive surgeon's mean case cost was $613, which was significantly less than the most expensive surgeon's $2243 (P = 0.009). The median cost range was $598-$784. The top quartile of cases resulted in 57% of overall material cost for ankle fractures. The mean intraoperative material cost per bicondylar tibial plateau fracture was $3219 (range $1839-$4088, P = 0.064). The range of median costs ($1826-$3989) was significantly wider than for ankle fractures. Bone void fillers, locking plates, adjunctive external fixators, mini-fragment locking plates, cannulated screws, single-use taps, guidewires, and drill bits all substantially increased costs.
Conclusion:
This study demonstrated variation in intraoperative material cost between 6 traumatologists resulting from practice variations despite similar specialty training. The cost differences resulting from practice variation reveal potential savings through increased standardization of surgical care for similar injuries. We identified high-cost items, which could lead to cost savings if used only when they will have clinical benefit.
