Health Care Disparities in Hysterectomy for Gynecologic Cancers: Data From the 2012 National Inpatient Sample

To examine hysterectomies in the United States performed for gynecologic malignancies and identify factors associated with the use of minimally invasive techniques. This is a cross-sectional analysis of the 2012 National Inpatient Sample, the largest national all-payer database of hospital discharges. International Classification of Diseases, 9th Revision, Clinical Modification codes for any type of hysterectomy performed for gynecologic malignancy were used to abstract pertinent observations. Weighted multivariable logistic regression models were used to examine the associations between demographic and clinical factors and mode of hysterectomy by cancer diagnosis. In 2012, there were an estimated 46,450 hysterectomies for gynecologic malignancy in the United States. Of these, 28,285 (61%) were performed for uterine, 4,275 (9%) for cervical, 12,370 (27%) for ovarian cancer, and 1,520 (3%) for other gynecologic malignancies. Minimally invasive hysterectomy was used in 50% of uterine, 43% of cervical, and 8.5% of ovarian cancer cases. Black women had decreased odds of undergoing minimally invasive hysterectomy for uterine (adjusted odds ratio [OR] 0.50, 95% confidence interval [CI] 0.40-0.0.63, P
