Readmission, reoperations, in-hospital mortality, and other adverse events were compared across surgeon and facility volumes.

Low-volume (LV) facilities had higher rates of readmission [hazard ratio (HR) 1.07, 95% confidence interval (CI), 1.05\u20131.17], pneumonia (HR 1.36, 95% CI, 1.22\u20131.51), wound complications (HR 1.24, 95% CI, 1.03\u20131.49), and mortality (HR 1.15, 95% CI, 1.04\u20131.27) but lower rates of acute renal failure (HR 0.90, 95% CI, 0.83\u20130.98), deep vein thrombosis (HR 0.66, 95% CI, 0.55\u20130.78), and acute respiratory failure (HR 0.77, 95% CI, 0.62\u20130.95) than high-volume (HV) facilities. Patients treated by LV surgeons had lower rates of readmission (HR 0.92, 95% CI, 0.87\u20130.97) and deep vein thrombosis (HR 0.78, 95% CI, 0.66\u20130.94) but higher rates of acute renal failure (HR 1.13, 95% CI, 1.04\u20131.22) than those treated by HV surgeons.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions:<\/jats:title>\n            <jats:p>There are increased rates of mortality, readmission, and certain complications when peritrochanteric femur fractures are surgically managed at LV hospitals compared with those managed at HV hospitals. Thus, the benefit of a high-volume surgical facility is apparent in mortality and readmissions but not all complications. There was no significant decrease in complications if fixation was performed by HV surgeons relative to LV surgeons.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Level of Evidence:<\/jats:title>\n            <jats:p>Therapeutic Level III.
