Operative Time and Cost Vary by Surgeon: An Analysis of Supracondylar Humerus Fractures in Children.

Operative time is a critical driver of cost in orthopedics and an important target for improving value in health care. This study used an archetypal pediatric orthopedic procedure to identify surgeon-dependent variability in operative time. The authors reviewed patients 12 years or younger treated with closed reduction and percutaneous pinning for extension-type supracondylar humerus fractures. Variability in operative time across surgeons was assessed. Surgeon experience at the time of the procedure and case volume (quarterly) were evaluated to explain variations in operative time. A total of 1472 patients were reviewed (57% Gartland type II and 43% type III fractures). Procedures were performed by 12 fellowship-trained pediatric orthopedists with 2 weeks to 32.8 years of experience. For individual surgeons, the mean operative time ranged from 20.4 to 33.7 minutes for type II fractures and from 31.0 to 46.8 minutes for type III fractures. There was significant variation across surgeons in mean operative time and cost (P<.001). Analysis showed no significant effect of surgeon experience or quarterly case volume. Surgeons' mean operative time for type II fractures was strongly positively correlated with their mean operative time for type III fractures (r2 =0.74). Mean operative time and cost for supracondylar humerus fracture closed reduction and percutaneous pinning vary significantly between surgeons, but this variation is not explained by experience or volume. Surgeons who required more time for type II fractures were also slower for type III fractures. Because of the high per minute cost of the operating room, surgeon variability significantly impacts cost. Identification and modification of sources of variation in surgeon behavior will allow for reduction in the cost of surgical care. [Orthopedics. 2019; 42(3):e317-e321.].
