Background: Over 1 million healthcare providers have participated in the Advanced Trauma Life Support course. No studies have evaluated factors that predict course performance. This study aims to identify these predictors., Methods: All participants taking the course at 2 centers over a 4-year period were identified. Demographics, background, and performance data were extracted. Participants who failed were compared with those who did not. Stepwise logistic regression analysis was used to identify independent risk factors for failure., Results: Seven hundred forty-four healthcare providers participated in the course; 89.5% passed and 10.5% failed. Failure rates were lowest (.0%) among Trauma/Surgical Critical Care (SCC) providers and highest among pediatric providers (28.6%). Stepwise logistic regression identified age greater than 55, English as a second language, pretest score less than 75, and non-Trauma/SCC and non-Emergency Medicine background as predictors of failure., Conclusions: A failure rate of 10.5% was demonstrated among the course participants. Age greater than 55, English as second language, pretest score less than 75, and non-Trauma/SCC and non-Emergency Medicine backgrounds were associated with failure. These subgroups may benefit from performance improvement measures., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Background: Thoracic aortic emergencies account for 10% of thoracic-related admissions in the United States and remain associated with high morbidity and mortality rates. Open repair has declined owing to the emergence of thoracic endovascular aortic repair (TEVAR), but data on emergency TEVAR use for acute aortic pathology remain limited. We therefore reviewed our experience., Methods: We retrospectively evaluated emergency descending thoracic aortic endovascular interventions performed at a single academic level 1 trauma center between January 2005 and August 2013 including all cases of traumatic aortic injury, ruptured descending thoracic aneurysm, penetrating atherosclerotic ulcer, aortoenteric fistula, and acute complicated type B dissection. Demographics, clinical data, and outcomes were extracted. Stepwise logistic regression was used to identify independent risk factors for death., Results: During the study period, 51 patients underwent TEVAR; 22 cases (43.1%) were performed emergently (11 patients [50.0%] traumatic aortic injury; 4 [18.2%] ruptured descending thoracic aneurysm; 4 [18.2%] complicated type B dissection; 2 [9.1%] penetrating aortic ulcer; and 1 [4.5%] aortoenteric fistula). Overall, 72.7% (n = 16) were male with a mean age of 54.8 ± 15.9 years. Nineteen patients (86.4%) required only a single TEVAR procedure, whereas 2 (9.1%) required additional endovascular therapy, and 1 (4.5%) open thoracotomy. Four traumatic aortic injury patients required exploratory laparotomy for concomitant intra-abdominal injuries. During a mean hospital length of stay of 18.9 days (range, 1 to 76 days), 3 patients (13.6%) developed major complications. In-hospital mortality was 27.2%, consisting of 6 deaths from traumatic brain injury (1); exsanguination in the operating room before repair could be achieved (2); bowel ischemia (1) and multisystem organ failure (1); and family withdrawal of care (1). A stepwise logistic regression model identified 24-hour packed red blood cell requirements ≥4 units, admission mean arterial pressure <60 mm Hg, and 24-hour fresh frozen plasma to packed red blood cell (pRBC) ratio <1:1.5 as independent risk factors for death in this cohort. During a mean follow-up of 369 days (range, 35 to 957 days), no subsequent major complications or deaths occurred. All patients underwent serial computed tomographic angiography surveillance, and no device-related problems were identified during intermediate follow-up., Conclusions: Thoracic aortic emergencies remain challenging. Our experience in a moderate-volume center supports the utilization of TEVAR in the acute setting. Twenty-four-hour pRBC requirements ≥4 units, admission mean arterial pressure <60 mm Hg, and 24 hour fresh frozen plasma to pRBC ratio <1:1.5 were independently associated with death., (Copyright © 2014 Elsevier Inc.

Background: The purpose of this study was to evaluate the impact of the transition to acute care surgery (ACS) on trauma volumes and outcomes., Methods: All admissions from 2 1-year periods from June 2008 to May 2010 (1 year before ACS and 1 year after ACS) to the LAC+USC Medical Center were prospectively collected. In anticipation of this change, trauma patient demographics, clinical data, and outcomes (trauma volume and preventable and potentially preventable deaths and complications) were prospectively collected., Results: Before ACS, there were 5,378 trauma admissions. After ACS, there were 5,726 (66.5%) trauma and 2,886 (33.5%) nontrauma admissions. There were no demographic or clinical differences between trauma patients in the 2 groups. There was no significant difference in overall mortality (3.8% before ACS vs 3.3% after ACS, P = .292). Similarly, there were no differences in the rates of preventable and potentially preventable deaths or complications observed (1.2% vs 1.0%, P = .374) during the study period., Conclusions: Despite a 60% increase in total patient volume and a 233% increase in operative volume over the study period, the addition of emergency surgery to a trauma service did not compromise trauma patient outcomes., (Copyright © 2013 Elsevier Inc.

Background: postoperative adhesions are a significant health problem with major implications on quality of life and health care expenses. The purpose of this review was to investigate the efficacy of preventative techniques and adhesion barriers and identify those patients who are most likely to benefit from these strategies., Methods: the National Library of Medicine, Medline, Embase, and Cochrane databases were used to identify articles related to postoperative adhesions., Results: ileal pouch-anal anastomosis, open colectomy, and open gynecologic procedures are associated with the highest risk of adhesive small-bowel obstruction (class I evidence). Based on expert opinion (class III evidence) intraoperative preventative principles, such as meticulous hemostasis, avoiding excessive tissue dissection and ischemia, and reducing remaining surgical material have been published. Laparoscopic techniques, with the exception of appendicitis, result in fewer adhesions than open techniques (class I evidence). Available bioabsorbable barriers, such as hyaluronic acid/carboxymethylcellulose and icodextrin 4% solution, have been shown to reduce adhesions (class I evidence)., Conclusions: postoperative adhesions are a significant health problem with major implications on quality of life and health care. General intraoperative preventative techniques, laparoscopic techniques, and the use of bioabsorbable mechanical barriers in the appropriate cases reduce the incidence and severity of peritoneal adhesions., (2011 Elsevier Inc.
