Abstract Introduction The impact of safety net (SN) hospitals relative to racial and healthcare disparities remains largely unknown. Methods Using the Nationwide Inpatient Sample, adults undergoing coronary artery bypass grafting, colectomy, or total hip arthroplasty were identified. Multivariable regression analysis was performed to determine association between SN burden and outcomes. Within each SN burden tier, the association between race/ethnic group and outcomes was defined. Results Overal...

Introduction The relationship and trends of geography and travel distance to access surgical cancer care has been poorly characterized. The objective of the study was to define the geographic distribution of access to hospital-based operative cancer care across the USA.

Abstract Background Previous studies have largely examined social determinants of health relative to individual surgery quality metrics. We sought to characterize possible differences in “textbook outcome,” a composite measure of quality, relative to social vulnerability index. Methods The Medicare Standard Analytical Files from 2013 to 2017 were used to identify beneficiaries who underwent hepatopancreatic surgery. Individuals were stratified into 3 groups dependent on their social vulnerabilit...

BACKGROUND: There has been a dramatic increase in worldwide health care spending over the last several decades. Operative procedures and perioperative care in the USA represent some of the most expensive episodes per patient. In view of both the rising cost of health care in general and the rising cost of surgical care specifically, policymakers and stakeholders have sought to identify ways to increase the value-improving quality of care while controlling (or diminishing) costs. In this context,...

Nearly 60 million people live in a rural area across the United States. Since 2005, 162 rural hospitals have closed, and the rate of rural hospital closures seems to be accelerating. Major drivers of rural hospital closures are poor financial health, aging facilities, and low occupancy rates. Rural hospitals are particularly vulnerable to policy and market changes, and even small changes can have a disproportionate effect on rural hospital financial viability. Surgery can be safely performed in ...

While better outcomes at high-volume surgical centers have driven the regionalization of complex surgical care, access to high-volume centers often requires travel over longer distances. We sought to evaluate the travel patterns among patients undergoing esophagectomy to assess willingness of patients to travel for surgical care. The California Office of Statewide Health Planning database was used to identify patients who underwent esophagectomy between 2005 and 2016. Total distance traveled, as...

Abstract Purpose We examined differences in critical care structures and processes between hospitals with Acute Care Surgery (ACS) versus general surgeon on call (GSOC) models for emergency general surgery (EGS) care. Methods 2811 EGS-capable hospitals were surveyed to examine structures and processes including critical care domains and ACS implementation. Differences between ACS and GSOC hospitals were compared using appropriate tests of association and logistic regression models. Results 272/1...

Abstract Background While variation in outcomes has driven centralization of complex cancer surgery, variation in cost and value remains unexplored. We evaluated outcomes relative to cost among hospitals performing esophageal and pancreatic resection for cancer. Methods Using 100% Medicare claims data, we identified fee-for-service Medicare patients undergoing elective esophagectomy and pancreatectomy for cancer from 2014 to 2016. Risk- and reliability-adjusted, price-standardized payments for t...
