Objective: This study evaluates the relationship between hospital and surgeon volumes of peritrochanteric hip fracture fixation and complication rates.Methods: Adults (60 years of age or older) who underwent surgical fixation for closed peritrochanteric fractures from 2009 to 2015 were identified using International Classification of Diseases 9 and 10 Clinical Modification and Procedural codes in the New York Statewide Planning and Research Cooperative System database. Readmission, reoperations, in-hospital mortality, and other adverse events were compared across surgeon and facility volumes. Statistical significance was set at P , 0.05.Results: A total of 29,656 patients were included in the study. Lowvolume (LV) facilities had higher rates of readmission [hazard ratio (HR) 1.07, 95% confidence interval (CI), 1.05-1.17], pneumonia (HR 1.36, 95% CI, 1.22-1.51), wound complications (HR 1.24, 95% CI, 1.03-1.49), and mortality (HR 1.15, 95% CI, 1.04-1.27) but lower rates of acute renal failure (HR 0.90, 95% CI, 0.83-0.98), deep vein thrombosis (HR 0.66, 95% CI, 0.55-0.78), and acute respiratory failure (HR 0.77, 95% CI, 0.62-0.95) than high-volume (HV) facilities. Patients treated by LV surgeons had lower rates of readmission (HR 0.92, 95% CI, 0.87-0.97) and deep vein thrombosis (HR 0.78, 95% CI, 0.66-0.94) but higher rates of acute renal failure (HR 1.13, 95% CI, 1.04-1.22) than those treated by HV surgeons.Conclusions: 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.

Background: Despite strong evidence supporting the efficacy of surgical release for carpal tunnel syndrome (CTS), previous studies have suggested that surgery is not performed equally amongst races and sex. The purpose of this study was to investigate potential socioeconomic disparities in the surgical treatment for CTS. Methods: Adult patients (≥18) were identified in the New York Statewide Planning and Research Cooperative System database from 2011 to 2018 by diagnosis code for CTS. All carpal tunnel surgery procedures in the outpatient setting were identified using Current Procedural Terminology codes. Using a unique identifier for each patient, the diagnosis data were linked to procedure data. A multivariable logistic regression was performed to assess the impact of patient factors on the likelihood of receiving surgery. Results: In total, 92,921 patients with CTS were included in the analysis and 30,043 (32.3%) went on to have surgery. Older age and workers compensation insurance had increased the odds of surgery. Feminine gender had lower odds of surgery. Asian, African American, and other races had decreased odds of surgery relative to the White race. Patients of Hispanic ethnicity had decreased odds of surgery compared with non-Hispanic ethnicity. Patients with Medicare, Medicaid, or self-pay insurance were all less likely to undergo surgery relative to private insurance. Higher social deprivation was also associated with decreased odds of surgery. Conclusions: Surgical treatment of CTS is unequally distributed amongst gender, race, and socioeconomic status. Additional research is necessary to identify the cause of these disparities to improve equity in patient care.
