Abstract Background Continuous-flow left ventricular assist device (LVAD) implantation is a payor sensitive procedure influenced by preoperative comorbidities and social factors. Whether expansion in insurance coverage will further influence device utilization is unknown. This study sought to assess the effects of Medicaid expansion on vulnerable populations (namely racial–ethnic minorities and those with low-income status) undergoing continuous-flow LVAD implantation after the enactment of the ...

Abstract Background Obesity disproportionately affects vulnerable populations. Bariatric surgery is an effective long-term treatment for obesity-related complications; however, bariatric surgical rates are lower among racial minorities and low-income and publicly insured patients. The Affordable Care Act’s Medicaid expansion improved access to health insurance, but its impact on bariatric surgical disparities has not been evaluated. We sought to determine the impact of the Affordable Care Act’s ...

Abstract Background The Affordable Care Act Medicaid expansion demonstrated inconsistent effects on cancer surgery utilization rates among racial and ethnic minorities and low-income Americans. This quasi-experimental study examines whether Medicaid expansion differentially increased the utilization of surgical cancer care for low-income groups and racial minorities in states that expanded their Medicaid programs. Methods A cohort of more than 81,000 patients 18 to 64 years of age who underwent ...

Purpose:Surgery continues to be the dominant therapy for the management of retroperitoneal soft-tissue sarcoma (RPS). Many groups advocate performing these resections at high-volume hospitals (HVHs), given their complexity. We therefore sought to explore whether RPS surgery has indeed begun to regionalize to HVHs in the same manner as pancreatic cancer (PC) surgery during the last decade.Methods:We identified 70,763 patients who underwent surgical resection for RPS or PC using the National Cance...

Background Adequate lymphadenectomy (AL) of 15+ lymph nodes comprises an important component of gastric cancer surgical therapy. Despite endorsement by the National Comprehensive Cancer Network and the Committee on Cancer, initial adoption of this paradigm has been relatively slow. The current analysis sought to perform an adjusted time-trend evaluation of the factors associated with AL and its dissemination.

ABSTRACT Background While pre-Affordable Care Act expansions in Medicaid eligibility led to increased utilization of elective inpatient procedures, the impact of the Affordable Care Act on such preference-sensitive procedures (also known as discretionary procedures) versus time-sensitive non-discretionary procedures remains unknown. As such, we performed a hospital-level quasi-experimental evaluation to measure the differential effects of the Affordable Care Act's Medicaid expansion on utilizati...
