The Effect of Surgeon and Hospital Volume on Morbidity and Mortality After Femoral Shaft Fractures.

OBJECTIVES

The aim of this study was to characterize the case volume dependence of both facilities and surgeons on morbidity and mortality after femoral shaft fracture (FSF) fixation.

METHODS

Adults who had an open or closed FSF between 2011 and 2015 were identified in the New York Statewide Planning and Research Cooperative System database. Claims were identified by International Classification of Disease-9, Clinical Modification diagnostic codes for a closed or open FSF and International Classification of Disease-9, Clinical Modification procedure codes for FSF fixation. Readmission, in-hospital mortality, and other adverse events were compared across surgeon and facility volumes using multivariable Cox proportional hazards regression, controlling for patient demographic and clinical factors. Surgeon and facility volumes were compared between the lowest and highest 20% to represent low-volume and high-volume surgeons/facilities.

RESULTS

Of 4,613 FSF patients identified, 2,824 patients were treated at a high or low-volume facility or by a high or low-volume surgeon. Most of the examined complications including readmission and in-hospital mortality showed no statistically significant differences. Low-volume facilities had a higher 1-month rate of pneumonia. Low-volume surgeons had a lower 3-month rate of pulmonary embolism.

CONCLUSION

There is minimal difference in outcomes in relation to facility or surgeon case volume for FSF fixation. As a staple of orthopaedic trauma care, FSF fixation is a procedure that may not require specialized orthopaedic traumatologists at high-volume facilities.
