Article Synopsis
  • Researchers developed and validated a clinical risk index score called NECROSIS to help identify necrotizing soft tissue infections (NSTIs) in emergency patients with severe skin issues.
  • *The study involved analyzing data from 362 adult patients across 16 sites in the US, finding that 82% were diagnosed with NSTIs, with key predictors including low blood pressure, specific skin color changes, and elevated white blood cell counts.
  • *The NECROSIS score showed good predictive validity, suggesting it could be a valuable tool for clinicians, though further validation studies are needed.*

Background: There are no current consensus guidelines that address screening patients who may have occult major venous injury in the setting of penetrating thigh trauma. Yet, such injuries confer significant morbidity and mortality to trauma patients if left untreated.

Methods: This paper examines the cases of three patients who presented to our single level I trauma center after sustaining penetrating thigh trauma with negative CT arteriography, all of whom were eventually diagnosed with occult major venous injury.

Background: High-quality CT can exclude hollow viscus injury (HVI) in patients with abdominal seatbelt sign (SBS) but performs poorly at identifying HVI. Delay in diagnosis of HVI has significant consequences necessitating timely identification.

Study Design: This multicenter, prospective observational study conducted at 9 trauma centers between August 2020 and October 2021 included adult trauma patients with abdominal SBS who underwent abdominal CT before surgery.

Background: Contemporary nationwide outcomes of gallstone pancreatitis (GSP) managed by cholecystectomy at the index hospitalization are limited. This study aims to define the rate of 30-day morbidity and mortality and identify associated perioperative risk factors in patients undergoing cholecystectomy for GSP.

Methods: Patients from the ACS-NSQIP database with GSP without pancreatic necrosis, who underwent cholecystectomy during the index hospitalization from 2017 to 2019 were selected.

Importance: Abdominal seat belt sign (SBS) has historically entailed admission and observation because of the diagnostic limitations of computed tomography (CT) imaging and high rates of hollow viscus injury (HVI). Recent single-institution, observational studies have questioned the utility of this practice.

Objective: To evaluate whether a negative CT scan can safely predict the absence of HVI in the setting of an abdominal SBS.

Introduction: Necrotizing soft tissue infections (NSTIs) carry high morbidity and mortality. While early aggressive surgical debridement is well-accepted treatment for NSTIs, the optimum duration of adjunct antibiotic therapy is unclear. An increasing focus on safety and evidence-based antimicrobial stewardship suggests a value in addressing this knowledge gap.

Introduction: We sought to determine the impact of the indication for shunt placement on shunt-related outcomes after major arterial injuries. We hypothesized that a shunt placed for damage control indications would be associated with an increase in shunt-related complications including shunt dislodgement, thrombosis, or distal ischemia.

Patients & Methods: A prospective, multicenter study (eleven level one US trauma centers) of all adult trauma patients undergoing temporary intravascular shunts (TIVS) after arterial injury was undertaken (January 2017-May 2019).

Objective: Several reports have found helicopter emergency medical services (HEMS) to be associated with a lower risk of mortality compared with ground emergency medical services (GEMS); however, most studies did not control for transport time or stratify interfacility versus scene. We hypothesize that the HEMS transport rate has decreased nationally and that the risk of mortality for HEMS is similar to GEMS when adjusting for transport time and stratifying by scene or interfacility.

Methods: The Trauma Quality Improvement Program (2010-2016) was queried for adult patients transported by HEMS or GEMS.

Background: Trauma is the leading cause of nonobstetric death during pregnancy and is associated with an increased risk of maternal and fetal mortality. In an effort to improve the delivery of care to pregnant trauma patients, we developed an institutional multidisciplinary quality initiative designed to improve response times of nontrauma specialists and ensure immediate availability of resources. We hypothesized that implementation of a perinatal emergency response team (PERT) would improve time to patient and fetal evaluation and monitoring by the obstetrics (OB) team and improve both maternal and fetal outcomes.
