Abstract Background Mental illness and depression can be associated with increased risk of suicidal ideation (SI). We sought to determine the association between mental illness and SI among cancer surgical patients. Methods Medicare beneficiaries who underwent resection of lung, esophageal, pancreatic, colon, or rectal cancer were analyzed. Patients were categorized as no mental illness, anxiety and/or depression disorders or bipolar/schizophrenic disorders. Results Among 211,092 Medicare benefi...

INTRODUCTION While the impact of demographic factors on postoperative outcomes has been examined, little is known about the intersection between social vulnerability and residential diversity on postoperative outcomes following cancer surgery. METHODS Individuals who underwent a lung or colon resection for cancer were identified in the 2016-2017 Medicare database. Data were merged with the Centers for Disease Control and Prevention social vulnerability index and a residential diversity index was...

BACKGROUND The association of different social vulnerability subthemes (ie, socioeconomic status, household composition and disability, minority status and language, and housing and transportation) with surgical outcomes remains poorly defined. The current study aimed to identify distinct profiles of social vulnerability among Medicare beneficiaries and define the association of these profiles with postoperative outcomes. METHODS The Medicare 100% Standard Analytic Files were used to identify pa...

INTRODUCTION Residential racial desegregation has demonstrated improved economic and education outcomes. The degree of racial community segregation relative to surgical outcomes has not been examined. PATIENTS AND METHODS Patients undergoing pancreatic resection between 2013 and 2017 were identified from Medicare Standard Analytic Files. A diversity index for each county was calculated from the American Community Survey. Multivariable mixed-effects logistic regression with a random effect for ho...

Purpose null Digit null replantation null can improve dexterity, functionality, patient satisfaction, and pain following amputation, but rates continue to fall nationally. This study aimed to describe the effects of travel time and distance as barriers to high-volume hospitals, identify geospatial inefficiencies in the presentation of patients to replantation care, and provide an optimal allocation model in which cases are redistributed to select centers to reduce geospatial redundancies and opt...

Abstract null null Background null The objective of the current study was to assess the impact of case mix index at the hospital level on postoperative outcomes among Medicare beneficiaries who underwent hepatopancreatic surgery. null null null Methods null Medicare beneficiaries who underwent hepatopancreatic surgery between 2013 and 2017 were identified and analyzed. The primary independent variable, Case Mix Index, is a freely available metric; the primary outcome was textbook outcome defined...

BACKGROUND Better outcomes at high-volume surgical centers have driven regionalization of complex surgical care. In turn, access to high-volume centers often requires travel over longer distances. We sought to characterize travel patterns among patients who underwent a hepatectomy. METHODS The California Office of Statewide Health Planning database was used to identify patients who underwent hepatectomy between 2005 and 2016. Total distance traveled and whether a patient bypassed the nearest hos...
