Although the use of robotic-assisted surgery continues to expand, cost-effectiveness this platform remains unclear. The present study aimed compare hospitalization costs and clinical outcomes between laparoscopic approaches for major abdominal operations.All adults receiving minimally invasive gastrectomy, cholecystectomy, colectomy (right, left, transverse, sigmoid), ventral hernia repair, hysterectomy, abdominoperineal resection were identified in 2012 2019 National Inpatient Sample....
Background Although postoperative cardiac arrest is a well-studied complication of surgery, few guidelines exist regarding timing surgery in preoperative (pCA). We examined the association between delayed operation and outcomes following large cohort pCA. Methods Adults with diagnosis pCA undergoing were identified 2016-2020 National Inpatient Sample. Those requiring within 24 hours fo excluded. Patients who underwent procedure after 5 days cardiopulmonary resuscitation classified as Delayed...
While considered standard of care for obesity management, bariatric surgery is uncommon in patients with co-morbid inflammatory bowel disease (IBD).
Prior work has linked body mass index (BMI) with postoperative outcomes of ventral hernia repair (VHR), though recent data characterizing this association are limited. This study used a contemporary national cohort to investigate the between BMI and VHR outcomes.Adults ≥ 18 years undergoing isolated, elective, primary were identified using 2016-2020 American College Surgeons National Surgical Quality Improvement Program database. Patients stratified by BMI. Restricted cubic splines utilized...
To assess the impact of congenital heart disease (CHD) on resource utilisation and clinical outcomes in patients undergoing major elective non-cardiac operations.Due to advances cardiac management recent years, more with CHD are living into adulthood requiring operations.The 2010-2018 Nationwide Readmissions Database was used identify all adults operations (pneumonectomy, hepatectomy, hip replacement, pancreatectomy, abdominal aortic aneurysm repair, colectomy, gastrectomy oesophagectomy)....
With limited national studies available, we characterized the association of frailty with outcomes surgical resection for colonic volvulus.Adults sigmoid or cecal volvulus undergoing non-elective colectomy were identified in 2010-2019 Nationwide Readmissions Database. Frailty was using Johns Hopkins indicator which utilizes administrative codes. Multivariable models developed to examine in-hospital mortality, perioperative complications, stoma use, length stay, hospitalization costs,...
With a large body of literature demonstrating positive volume-outcome relationships for most major operations, minimum volume requirements have been suggested concentration cases to high-volume centers (HVCs). However, data are limited regarding disparities in access these hospitals pancreatectomy patients.The 2005-2018 National Inpatient Sample (NIS) was queried all elective adult hospitalizations pancreatectomy. Hospitals performing more than 20 annual were classified as HVCs....
The optimal timing of noncardiac surgery (NCS) following transcatheter aortic valve replacement (TAVR) for stenosis has not been elucidated by current national guidelines. aim this study was to evaluate the effect time interval between TAVR and NCS (Δt) on perioperative risk major adverse events (MAEs). All adult admissions isolated were identified in 2016 2020 Nationwide Readmissions Database. Patients who received subsequent admission included analysis grouped Δt as follows: ≤30, 31 60, 61...
Background Current guidelines recommend 24-hour telemetry monitoring for isolated sternal fractures (ISFs) with electrocardiogram (ECG) abnormalities or troponin elevation. However, a single-center study suggested ISF patients minor ECG (sinus tachycardia/bradycardia, nonspecific arrhythmia/ST-changes, and bundle branch block) may not require monitoring. This sought to corroborate this, hypothesizing would develop blunt cardiac injury (BCI). Materials & Methods A retrospective was...
Robotic approaches have been increasingly utilized for cardiothoracic operations, though concerns regarding costs remain. We evaluated short-term outcomes and of robotic-assisted conventional mitral valve repair (MV-repair), hypothesizing that cost differences would be mitigated at high-volume programs.
While the impact of socioeconomic status (SES) on surgical outcomes has been examined in limited series, it remains a significant determinant healthcare at national level. Therefore, current study aims to determine SES disparities three time-points: hospital accessibility, in-hospital outcomes, and post-discharge consequences. The Nationwide Readmissions Database 2010–2018 was used isolate major elective operations. assigned using previously coded median income quartiles as defined by...
While safety-net hospitals (SNH) play a critical role in the care of underserved communities, they have been associated with inferior postoperative outcomes. This study evaluated association hospital status clinical and financial outcomes following esophagectomy.All adults (≥18 years) undergoing elective esophagectomy for benign malignant gastroesophageal disease were identified 2010-2019 Nationwide Readmissions Database. Centers highest quartile proportion uninsured/Medicaid patients...
ObjectivesExpedited discharge after coronary artery bypass grafting (CABG) has been postulated as a possible solution for reducing hospitalization costs. This study aimed to evaluate the impact of expedited postoperative on readmissions and costs in patients undergoing isolated CABG.DesignAdults (≥18 years) who underwent CABG were identified using 2016-to-2019 Nationwide Readmission Database. Patients classified or routine, with being discharged before day 4. Those experienced perioperative...
Conversion to open is a potentially serious intraoperative event associated with minimally invasive pulmonary lobectomy. However, the impact of institutional expertise on conversion has not been studied large scale. We used nationally representative database evaluate association between hospital lobectomy caseload and rates open.All adults who underwent were identified from 2017 2019 Nationwide Readmissions Database. Annual caseloads independently tabulated. Restricted cubic splines...
With recent studies demonstrating the efficacy of minimally invasive approaches following infected necrotizing pancreatitis, latest guideline recommendations support their use. However, large-scale are lacking, and national landscape these guidelines remains poorly characterized. The present study examined trends in intervention strategies association approach on clinical outcomes resource use a nationally representative cohort.The 2016-2019 National Inpatient Sample was queried for adult...
Background Despite the known advantages of minimally invasive surgery (MIS) for diverticular disease, impact conversions to open (CtO) colectomy remains understudied. The present study used a nationally representative database characterize risk factors and outcomes associated with CtO in patients disease. Methods All elective adult hospitalizations entailing diverticulitis were identified 2017–2019 Nationwide Readmissions Database. Annual institutional caseloads MIS independently tabulated....
Care fragmentation (CF), or readmission at a nonindex hospital, has been linked to inferior clinical and financial outcomes for patients. However, its impact on patients with acute myocardial infarction (AMI) is unclear. This study investigated the prevalence of CF AMI. All US adult (≥18 years) hospitalizations AMI from January 2010 November 2019 were identified using Nationwide Readmissions Database. Patients stratified by an index center. Multivariable models developed evaluate factors...
Background Expedited discharge following esophagectomy is controversial due to concerns for higher readmissions and financial burden. The present study aimed evaluate the association of expedited with hospitalization costs unplanned malignant lesions. Methods Adults undergoing elective cancer were identified in 2014–2019 Nationwide Readmissions Database. Patients discharged by postoperative day 7 considered others as Routine . who did not survive or had major perioperative complications...
Abstract Background The adoption of RAC remains limited due to high costs. There is a paucity data regarding the impact institutional robotic experience on costs in patients undergoing for colorectal cancer. Methods All adult cancer were identified using 2016-2020 Nationwide Readmissions Database. A multivariable regression model major adverse events (MAE) was developed with inclusion surgery volume as restricted cubic splines. corresponding inflection point spline used stratify hospitals...
