Importance  The Model for End-Stage Liver Disease (MELD) score is predictive of trauma outcomes.

Objective  To determine whether a decrease in MELD score is associated with improved mortality in critically ill trauma patients.

Design, Setting, and Participants  We performed a retrospective registry study of critically ...

Invited Commentary 
Matthew J. Martin, MD

To say that we are “operating in the dark” when it comes to venous thromboembolism (VTE) screening and prophylaxis in children is an understatement. In this issue of JAMA Surgery, Connelly and colleagues1 have published a technically well-done statistical analysis of the National Trauma Data Bank ...

Invited Commentary 
Todd E. Rasmussen, MD

In characterizing the effect of a 2009 mandate to reduce medical evacuation times in Afghanistan, in this issue of JAMA Surgery, Kotwal and colleages1 demonstrate the effectiveness of combining advanced trauma care capability with informed policy. Unlike any report before it, this study demonstrates that one ...

Timothy A. Pritts, MD, PhD

Care of the critically ill patient with cirrhosis of the liver is a significant challenge for all surgeons and intensivists. The occurrence of a traumatic injury in a patient with otherwise compensated liver disease may lead to acute-on-chronic liver failure with a high risk of death, even after ...

To the Editor Despite the statistics systematically summarized by Hempel and collegues1 in a recent issue of JAMA Surgery, never events (ie, serious, preventable surgical events) have enormously emotional aspects that touch everyone involved. Out of an unlimited number of possible surgical complications, never events carry ...

Importance  Physical examination misses up to one-third of ventral hernia recurrences seen on radiologic imaging. However, tests such as computed tomographic (CT) imaging are subject to interpretation and require validation of interobserver reliability.

Objective  To determine the interobserver reliability of CT scans for detecting a ventral ...

Importance  Aortic clamping technique has been implicated in stroke risk at the time of on-pump coronary artery bypass grafting (CABG) procedures. We hypothesized that partial aortic clamping (PAC) use in performing proximal coronary anastomosis does not increase risk of stroke.

Objective  To determine whether postoperative stroke ...

Invited Commentary: Partial vs Single Aortic Clamping; Michael D. Crittenden, MD
Invited Commentary 
Melissa Anne Mallory, MD; Stanley W. Ashley, MD

Ventral hernias (VHs) are common in the United States, with more than 350 000 repairs performed annually.1 Nevertheless, consensus regarding the optimal technique for VH repair is lacking and recurrence rates remain high (approaching 50% in some series), suggesting we are not quite ready to close the book ...

Invited Commentary 
Michael D. Crittenden, MD

Once cardiopulmonary bypass became a clinical reality, the application of a noncrushing clamp across the ascending aorta allowed pioneering surgeons to correct congenital and acquired heart disease under direct vision. Favaloro et al1 described using partial aortic clamping (PAC) for proximal anastomoses for coronary operations at the ...

To the Editor We read the Viewpoint by Schecter1 with interest. The training of surgical educators is paramount in addressing the wide global disparities in surgical care provision, and we commend the efforts of the Alliance for Global Clinical Training in developing academic surgical services at the ...

Importance  Under bundled payment programs, hospitals receive a single payment for all services provided surrounding an episode of care. Because health care providers, such as hospitals and physicians, accept more financial risk under these programs, they will need a better understanding of episode costs to identify areas ...

Importance  It has been well recognized that metabolic surgery has short-term benefits for mildly obese patients with type 2 diabetes mellitus (T2DM), but how long these effects can be sustained is uncertain.

Objective  To compare the 5-year efficacy between gastrointestinal metabolic surgery and medical treatment on ...

Invited Commentary 
Kenric M. Murayama, MD

Proponents of a movement away from the traditional fee-for-service model of reimbursement for health care argue that it results in unnecessary use of services and interventions by rewarding volume and not value, increasing the cost of care. In 1984, Medicare instituted the diagnostic-related group model in an effort ...

Invited Commentary 
Robin P. Blackstone, MD

Metabolic and bariatric surgery (MBS) is shown to be more effective in the treatment of type 2 diabetes mellitus and obesity than medical weight loss in the retrospective study comparing surgical and medical cohorts with body mass index (BMI; calculated as weight in kilograms divided by height in ...

To the Editor Mohanty and colleagues have published an excellent description of the updated American College of Surgeons (ACS) Risk Calculator, which now includes the outcome of “risk of discharge to postacute care.”1 In contrast to previous work,2 the updated ACS Risk Calculator provides estimates of ...

In Reply In our study, we examined the risk of discharge to postacute care for several operations. We subsequently built the outcome into the American College of Surgeons National Surgical Quality Improvement Program Surgical Risk Calculator (http://riskcalculator.facs.org/) for all operations captured by the National Surgical Quality ...
