Background: Witnessing death can be difficult and emotionally draining for health care workers and presents a risk factor for burnout. The practice of a ritual pause at patient death to recognize the patient as a person, reflect, and acknowledge the health care team is an emerging intervention that has not been well studied in trauma.

Objective: This study aims to explore the effect of a team pause on trauma team member attitudes after emergency department patient death.

Background: Hypothermia is an uncommon, potentially life-threatening condition. We hypothesized (1) advanced rewarming techniques were more frequent with increased hypothermia severity, (2) active rewarming is increasingly performed with smaller intravascular catheters and decreased cardiopulmonary bypass, and (3) mortality was associated with age, hypothermia severity, and type.

Methods: Trauma patients with temperatures <35°C at 4 ACS-verified trauma centers in Wisconsin and Minnesota from 2006 to 2016 were reviewed.

Introduction: We hypothesized that trauma providers are reticent to consider palliative measures in acute trauma care.

Methods: An electronic survey based on four patient scenarios with identical vital signs and serious blunt injuries, but differing ages and frailty scores was sent to WTA and EAST members.

Results: 509 (24%) providers completed the survey.

Objective measures including the DeMeester score, lower esophageal sphincter (LES) pressure, acid exposure time, and body mass index (BMI) are used to determine gastroesophageal reflux disease (GERD) severity and eligibility for various antireflux surgical procedures. The GERD Health-Related Quality of Life (GERD-HRQL) survey is widely used to evaluate patients' subjective severity of symptoms and GERD-related quality of life. The purpose of this project was to identify whether or not the subjective measure (GERD-HRQL) correlated with objective measures (DeMeester score, LES, acid exposure time, and BMI) of GERD severity.

Objective: A chief resident service (CRS) provides a unique environment to assess competence throughout all aspects of patient care. The American College of Surgeons National Surgical Quality Improvement Program and Quality in Training Initiative databases are utilized to assess patient outcomes by individual residents with institutional and national comparisons. We hypothesized that residents on the CRS would have equivalent patient care outcomes to peers not on CRS and to chief residents nationally.

Background: Multi-detector computed tomography imaging is now the reference standard for identifying solid organ injuries, with a high sensitivity and specificity. However, delayed splenic hemorrhage (DSH), defined as no identified injury to the spleen on the index scan but delayed bleeding from a splenic injury, has been reported. We hypothesized that the occurrence of DSH would be minimized by utilization of modern imaging techniques.

Background: Some weight regain is expected after bariatric surgery; however, this concept is not well defined. A favorable weight loss response has commonly been defined as 50% excess weight loss (EWL). The medical literature uses %total weight loss (%TWL), which has recently been adopted in some surgical literature.
