Abstract
BACKGROUND While the use of the failure-to-rescue (FTR) metric, or death after complication, has expanded beyond elective surgery to emergency general surgery (EGS), little is known about the trajectories patients take from index complication to death. METHODS We conducted a retrospective cohort study of EGS operations using the National Surgical Quality Improvement Project (NSQIP) dataset, 2011-2017. 16 major complications were categorized as infectious, respiratory, thrombotic, cardiac, renal, neurologic, or technical. We tabulated common combinations of complications. We then use logistic regression analyses to test the hypotheses that (1) increase in the number and frequency of complications would yield higher FTR rates and (2) secondary complications that span a greater number of organ systems or mechanisms carry a greater associated FTR risk. RESULTS Of 329 183 EGS patients, 69 832 (21.2%) experienced at least 1 complication. Of the 11 195 patients who died following complication (16.0%), 8205 (63.4%) suffered more than 1 complication. Multivariable regression analyses revealed an association between the number of complications and mortality risk (odds ratio [OR] 2.37 for 2 complications vs 1, P < .001). There was a similar increase in mortality with increased complication accrual rate (OR 3.29 for 0.2-0.4 complications/day vs <0.2, P < .001). Increasing the number of types of complication were similarly associated with mortality risk. DISCUSSION While past FTR analyses have focused primarily on index complication, a broader consideration of ensuing trajectory may enable identification of high-risk cohorts. Efforts to reduce mortality in EGS should focus on attention to those who suffer a complication to prevent a cascade of downstream complications culminating in death.

Abstract
Interhospital transfer (IHT) is associated with mortality in medical and mixed intensive care units (ICUs), but few studies have examined this relationship in a surgical ICU (SICU) setting. We hypothesized that IHT is associated with increased mortality in SICU patients relative to ICU patients admitted within the hospital. We reviewed SICU and transfer center databases from a tertiary academic center over a 2-year period. Inclusion criteria included age 18 years or older and SICU admission 24 hours or greater. Demographic data, admission service, and Acute Physiology and Chronic Health Evaluation (APACHE) II scores were captured. The primary end point was ICU mortality. Univariate logistic regression was used to test the association between variables and mortality. Factors found to be associated with mortality at P < 0.1 were entered into a multivariable model. Of 4542 admissions, 416 arrived by IHT. Compared with the non-IHT group, the IHT group was older (age 58.3 years [interquartile range, 47.8 to 70.6] vs 57.8 years [interquartile range, 44.1 to 68.8] years, P = 0.036), sicker (APACHE II score 16.5 [interquartile range, 12 to 23] vs 14 [interquartile range, 10 to 20], P < 0.001), and more likely to be white (82% [n = 341] vs 69% [n = 2865], P < 0.001). Mortality rates in IHT patients were highest on the emergency surgery (18%), transplant surgery (16%), and gastrointestinal surgery (8%) services. After adjusting for age and APACHE II score, IHT remained a risk factor for ICU mortality (odds ratio, 1.60; 95% confidence interval, 1.04 to 2.45; P = 0.032) in SICU patients. Interhospital transfer is an independent risk factor for mortality in the SICU population; this risk is unevenly distributed through service lines. Further efforts to determine the cause of this association are warranted.

Abstract
Background There is no evidence supporting intubation for a Glasgow Coma Scale (GCS) of 8. We investigated the effect of intubation in trauma patients with a GCS 6–8, with the hypothesis that intubation would increase mortality and length of stay. Methods We studied adult patients with GCS 6–8 from the 2016 National Trauma Data Bank. Intubated and non-intubated patients were compared using inverse probability weighted regression adjustment (IPWRA) to control for injury severity and patient characteristics. Outcomes were mortality, intensive care unit length of stay (ICU LOS), and total LOS. Stratified analysis was performed to investigate the effect in patients with and without head injuries. Results Among 6676 patients with a GCS between 6 and 84,078 were intubated within 1 h of arrival to the emergency department. The overall mortality rate was 15.1%. IPWRA revealed an increase in mortality associated with intubation (OR 1.05, 95% CI 1.03, 1.06). The results were similar in patients with head injuries (OR 1.04, 95% CI 1.02, 1.06) and without (OR 1.06, 95% CI 1.03, 1.10). Among the 5,742 patients admitted to the ICU, intubation was associated with a 14% increase in ICU LOS (95% CI 8–20%; 5.5 vs. 4.8 days; p < 0.001). The overall length of stay was 27% longer (95% CI 19.8–34.3%) among intubated patients (mean 7.7 vs 6.0 days; p < 0.001). Conclusion Among patients with GCS of 6 to 8, intubation on arrival was associated with an increase in mortality and with longer ICU and overall length of stay. The use of a strict threshold GCS to mandate intubation should be revisited.

Cardiac complications and failure to rescue after injury in a mature state trauma system: Towards identifying opportunities for improvement. Injury 2020; 51:1216-1223. [PMID: 32122623 DOI: 10.1016/j.injury.2020.02.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Revised: 02/01/2020] [Accepted: 02/04/2020] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Cardiac complications (CC) after injury are rare but contribute disproportionately to mortality. Variability in rates of CC and failure to rescue (FTR) after CC (FTR-C) within trauma systems may suggest opportunities for improvement, but we have not yet demonstrated the ability to identify high and low performers. We examined center-level rates of CC and FTR-C in a mature trauma system with the hypothesis that high-performing centers for each of these outcomes could be identified. METHODS Using a statewide trauma registry from 2007-2015, we developed multivariable logistic regression models on CC and FTR-C including patient demographics, physiology, comorbidity, and injury data. Predicted probabilities of each outcome were summed to generate expected event rates, which were compared to observed event rates to generate centerlevel observed-to-expected (O:E) ratios. We measured internal consistency between CC and FTR-C for centers using Cronbach's alpha. RESULTS Cardiac complications occurred in 5,079/278,042 (1.8%; center-level range: 0.9-3.8%) of included patients (median age 55 (IQR 34-76), 84% Caucasian, 60% male, 92% blunt, median ISS 9 (IQR5-16)). Death after CC occurred in 982/5,097 patients for an FTR-C rate of 19.3% (center-level range: 7.8-30.4%). 10/27 centers were high-performers (95% confidence interval for O:E ratio <1) for CC and 2/27 centers were high-performers for FTR-C, but internal consistency between these metrics was poor (alpha = 0.31). CONCLUSION Rates of CC and FTR-C vary significantly between hospitals in mature trauma systems but high-performing centers can be identified. Inconsistent performance between metrics suggests unknown institutional factors underlie performance for CC and FTR.

Abstract
BACKGROUND Although obesity is considered an epidemic in the United States, there is mixed evidence regarding the impact of obesity on outcomes after traumatic injury and major surgery. We hypothesized that obese patients undergoing trauma laparotomy would be at increased risk of failure to rescue (FTR), defined as death after a complication. METHODS We analyzed trauma registry data for adult patients who underwent abdominal exploration for trauma at all 30 level I and II Pennsylvania trauma centers, 2011-2014. We used competing risks regression to identify significant risk factors for complications. We used multivariable logistic regression to identify significant risk factors for FTR. RESULTS Of 95,806 admitted patients, 15,253 (15.9%) were categorized as obese. Overall, 3228 (3.4%) underwent laparotomy, including 2681 (83.1%) nonobese and 547 (17.0%) obese patients. Among obese patients, 47.2% had at least one complication and 28.7% had two or more complications, compared with 33.5% and 18.7% of nonobese patients, respectively. The most common complication was pneumonia (15.0% of obese and 10.5% of nonobese patients; P = 0.003), followed by sepsis (8.8% versus 4.2%; P < 0.001) and deep vein thrombosis (8.4% versus 5.9%; P < 0.001). Obesity was independently associated with complications (hazard ratio, 1.4; 95% confidence interval, 1.2-1.6). In multivariable analysis, obesity was not associated with FTR (odds ratio, 1.3; 95% confidence interval, 0.9-2.0). CONCLUSIONS Obesity is a risk factor for complications after traumatic injury but not for FTR. The increased risk of complications may reflect processes of care that are not attuned to the needs of this population, offering opportunities for improvement in care.

Abstract
BACKGROUND Mortality in emergency general surgery (EGS) is often attributed to patient condition, which may obscure opportunities for improvement in care. Identifying failure to rescue (FTR), or death after complication, may reveal these opportunities. FTR has been problematic in trauma secondary to low precedence rates (proportion of deaths preceded by complication). We sought to evaluate this in EGS, hypothesizing that precedence is lower in EGS than in similar elective operations. METHODS National Inpatient Sample data from January 2014 through September 2015 were used. 150,027 adult operative EGS complete cases were defined by emergent admission, one of seven International Classification of Diseases, ninth revision (ICD-9) procedure group codes for common EGS operations, and timing to operation (<48 h); these represent 750,135 patients under the National Inpatient Sample sampling design. Deaths were precedented if one of eight prespecified complications was identified. Chi-squared tests were used to compare precedence rates between selected emergent and elective operations. RESULTS There was a 2.5% mortality rate in this cohort of operative EGS patients, with an 84.1% (95% CI: 82.7%-85.4%) precedence rate. Among the seven listed procedure groups, those with clinically reasonable elective analogs were cholecystectomy, colon resection, and laparotomy. Emergent versus elective precedence rates were 90.2% versus 82.0% (P = 0.004) for colon resection, 81.3% versus 86.8% (P = 0.26) for cholecystectomy, and 68.8% versus 92.7% (P < 0.001) for laparotomy. CONCLUSIONS Precedence rates in EGS were higher than expected and were similar to previously published rates in nonemergent surgery, suggesting that FTR is likely to be reliable using standard methodology. Management of complications after emergency operation may represent significant opportunities to prevent mortality.

The search for a simple injury score to reliably discriminate the risk of in-hospital mortality in South Africa. Surgery 2020; 167:836-842.

Abstract
BACKGROUND The Injury Severity Score and Trauma and Injury Severity Score are used commonly to quantify the severity of injury, but they require comprehensive data collection that is impractical in many low- and middle-income countries . We sought to develop an injury score that is more feasible to implement in low- and middle-income countries with discrimination similar to the Injury Severity Score and the Trauma and Injury Severity Score. METHODS Clinical data from KwaZulu-Natal, South Africa were used to compare the discrimination of the Injury Severity Score and the Trauma and Injury Severity Score with that of the 5, simple injury scores that rely primarily on physiologic data: Revised Trauma Score for Triage, "Mechanism, Glasgow Coma Scale, Age, Pressure" Score, Kampala Trauma Score, modified Kampala Trauma Score, and "Reversed Shock Index Multiplied by Glasgow Coma Scale" Score. RESULTS Data for 3,991 patients were analyzed. The Trauma and Injury Severity Score, the Injury Severity Score, and Kampala Trauma Score had similar discrimination (area under the receiver operating curve 0.85, 0.84, and 0.84, respectively). The simple injury scores demonstrated worse discrimination among patients presenting more than 6 hours postinjury, although Kampala Trauma Score maintained the best discrimination of the simple injury scores. CONCLUSION In this patient population, Kampala Trauma Score demonstrated discrimination similar to the Injury Severity Score and the Trauma and Injury Severity Score and may be useful to quantify the severity of injury when calculation of the Injury Severity Score or the Trauma and Injury Severity Score is not feasible. Delay in presentation can degrade the discrimination of simple injury scores that rely primarily on physiologic data.

Plasma Mitochondrial DNA Levels Are Associated With ARDS in Trauma and Sepsis Patients. Chest 2020; 157:67-76.

Abstract
BACKGROUND Critically ill patients who develop ARDS have substantial associated morbidity and mortality. Circulating mitochondrial DNA (mtDNA) released during critical illness causes endothelial dysfunction and lung injury in experimental models. This study hypothesized that elevated plasma mtDNA is associated with ARDS in critically ill patients with trauma and sepsis. METHODS Plasma mtDNA concentrations were measured at ED presentation and approximately 48 h later in separate prospective cohorts of critically ill patients with trauma and sepsis. ARDS was classified according to the Berlin definition. The association of mtDNA with ARDS was tested by using multivariable logistic regression, adjusted for covariates previously shown to contribute to ARDS risk in each population. RESULTS ARDS developed in 41 of 224 (18%) trauma patients and in 45 of 120 (38%) patients with sepsis. Forty-eight-hour mtDNA levels were significantly associated with ARDS (trauma: OR, 1.58/log copies/μL; 95% CI, 1.14-2.19 [P = .006]; sepsis: OR, 1.52/log copies/μL; 95% CI, 1.12-2.06 [P = .007]). Plasma mtDNA on presentation was not significantly associated with ARDS in either cohort. In patients with sepsis, 48-h mtDNA was more strongly associated with ARDS among those with a nonpulmonary infectious source (OR, 2.20/log copies/μL; 95% CI, 1.36-3.55 [P = .001], n = 69) than those with a pulmonary source (OR, 1.04/log copies/μL; 95% CI, 0.68-1.59 [P = .84], n = 51; P = .014 for interaction). CONCLUSIONS Plasma mtDNA levels were associated with incident ARDS in two critical illness populations. Given supportive preclinical data, our findings suggest a potential link between circulating mtDNA and lung injury and merit further investigation as a potentially targetable mediator of ARDS.

Abstract
BACKGROUND Evidence of a "weekend effect" is limited in emergency general surgery (EGS). We hypothesized that there are increased rates of complications, death, and failure-to-rescue (FTR) in patients undergoing weekend EGS operations. METHODS National Inpatient Sample (NIS) data, January 2014-September 2015 were used. Operative EGS patients were identified by ICD-9 procedure code and timing to operation. Complications were defined by ICD-9 code. We performed survey-weighted multivariable regression analyses. RESULTS Of 438,110 EGS patients, 103,450 underwent weekend operation. There was no association between weekend operation and FTR (OR 1.17; 95%CI 0.95-1.45) or complications (OR 1.04; 95%CI 0.97-1.13). There was a weekend effect on mortality (OR 1.22; 95%CI 1.02-1.46) and an interactive effect between weekend operation and teaching status on complications (teaching OR 1.22; 95%CI 1.15-1.29; interaction OR 1.13; 95%CI 1.03-1.25). CONCLUSIONS There is evidence for a "weekend effect" on mortality, but not complications or FTR, in this cohort.

Abstract
BACKGROUND Teamwork is a critical element of trauma resuscitation. Assessment tools such as T-NOTECHS (Trauma NOn-TECHnical Skills) exist, but correlation with patient outcomes is unclear. Using emergency department thoracotomy (EDT), we sought to describe T-NOTECHS scores during resuscitations. We hypothesized that patients undergoing EDT whose resuscitations had better scores would be more likely to have return of spontaneous circulation (ROSC). METHODS Continuously recording video was used to review all captured EDTs over a 24-mo period. We used a modification of the validated T-NOTECHS instrument to measure five domains on a 3-point scale (1 = best, 2 = average, 3 = worst). A total T-NOTECHS score was calculated by one of three reviewers. The primary outcome was ROSC. ROSC was defined as an organized rhythm no longer requiring internal cardiac compressions. Associations between variables and ROSC were examined using univariate regression. RESULTS Sixty-one EDTs were captured. Nineteen patients had ROSC (31%) and 42 (69%) did not. The median T-NOTECHS score for all resuscitations was 8 [IQR 6-10]. As demographic and injury data (age, gender, mechanism, signs of life) were not associated with ROSC in univariate analysis, they were not considered for inclusion in a multivariable regression model. The association between overall T-NOTECHS score and ROSC did not reach statistical significance, but examination of the individual components of the T-NOTECHS score demonstrated that, compared to resuscitations that had "average" (2) or "worst" (3) scores on "Assessment and Decision Making," resuscitations with a "best" score were 5 times more likely to lead to ROSC. CONCLUSIONS Although the association between overall T-NOTECHS scores and ROSC did not reach statistical significance, better scores in the domain of assessment and decision making are associated with improved rates of ROSC in patients arriving in cardiac arrest who undergo EDT. LEVEL OF EVIDENCE Level IV Therapeutic/Care Management.

Abstract
INTRODUCTION Trauma video review (TVR) for quality improvement and education in the United States has been described for nearly three decades. The most recent information on this practice indicated a declining prevalence. We hypothesized that TVR utilization has increased since most recent estimates. METHODS We conducted a survey of TVR practices at level I and level II US trauma centers. We distributed an electronic survey covering past, current, and future TVR utilization to the Eastern Association for the Surgery of Trauma membership. RESULTS 45.0% of US level I and level II trauma centers completed surveys. 71/249 centers (28.5%) had active TVR programs. The use of TVR did not differ between level I and level II centers (28.8% vs. 27.8%, p = 0.87). Respondents using TVR were overwhelmingly positive about its perception (median score 8, [IQR 6-9]; 10 = 'best') at their institutions. CONCLUSIONS TVR use at Level I centers has increased over the past decade. Increased TVR utilization may form the basis for multicenter studies comparing processes of care during trauma resuscitation.

Abstract
BACKGROUND Severe traumatic brain injury (TBI) patients are at high risk for early aspiration and pneumonia. How pneumonia impacts neurological recovery after TBI is not well characterized. We hypothesized that, independent of the cerebral injury, pneumonia after TBI delays and worsens neurological recovery and cognitive outcomes. METHODS Fifteen CD1 male mice were randomized to sham craniotomy or severe TBI (controlled cortical impact [CCI] - velocity 6 m/s, depth 1.0 mm) ± intratracheal lipopolysaccharide (LPS-2 mg/kg in 0.1 mL saline) as a pneumonia bioeffector. Neurological functional recovery by Garcia Neurologic Testing (GNT) and body weight loss were recorded daily for 14 days. On Days 6-14, animals underwent Morris Water Maze learning and memory testing with cued trials (platform visible), spatial learning trials (platform invisible, spatial cues present), and probe (memory) trials (platform removed, spatial clues present). Intergroup differences were assessed by the Kruskal-Wallis test with Bonferroni correction (p < 0.05). RESULTS Weight loss was greatest in the CCI + LPS group (maximum 24% on Day 3 vs. 8% [Sham], 7% [CCI], both on Day 1). GNT was lowest in CCI + LPS during the first week. Morris Water Maze testing demonstrated greater spatial learning impairment in the CCI + LPS group vs. Sham or CCI counterparts. Cued learning and long-term memory were worse in CCI + LPS and CCI as compared to Sham. CONCLUSION A pneumonia bioeffector insult after TBI worsens weight loss and mortality in a rodent model. Not only is spatial learning impaired, but animals are more debilitated and have worse neurologic performance. Understanding the adverse effects of pneumonia on TBI recovery is the first step d patients.

Trauma Surg Acute Care Open 2019; 4:e000316. [PMID: 31467983 PMCID: PMC6699718 DOI: 10.1136/tsaco-2019-000316] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2019] [Revised: 05/18/2019] [Accepted: 07/02/2019] [Indexed: 11/15/2022] Open
Abstract
Background Firearm injury is a major public health burden in the USA. Absent a single, reliable data source, researchers have attempted to describe firearm injury epidemiology using trauma registry data. To understand the implications of this approach, we compared trends in firearm assault incidence and case-fatality in Philadelphia over 10 years from two sources: the Pennsylvania Trauma Outcomes Study (PTOS), Pennsylvania’s state-mandated trauma registry, and the Philadelphia Police Department database (PPD) of firearm assaults. Methods We included PTOS firearm assault patients treated in Philadelphia County and PPD database firearm assault victims from 2005 to 2014. We calculated counts of fatal and non-fatal incidents using PTOS and PPD data. We used generalized linear models adjusted for seasonality to estimate temporal trends in firearm assault rates and case-fatality for both data sources and compared patient demographics and injury characteristics between the two. Results A total of 6988 PTOS and 14 172 PPD subjects met the inclusion criteria. In both data sets, firearm assault rates decreased significantly during the study period (PTOS: 5.19 vs. 3.43 per 10 000 person-years, change/year: −0.21, 95% CI −0.26 to –0.16; PPD: 10.97 vs. 6.70 per 10 000 person-years, change/year: −0.53, 95% CI −0.62 to –0.44). PTOS mean case-fatality rate was 26.5% and decreased significantly (change/year: −0.41, 95% CI −0.78% to 0.04%). PPD mean case-fatality rate was 18.9% with no significant change over time (p=0.41). Discussion Relative to PPD data, PTOS data underestimated firearm assault incidence and overestimated mortality. Trends in case-fatality rates were disparate across the two data sources. A true understanding of firearm injury in the USA requires comprehensive data collection on the incidence, nature, and severity of these injuries. As trauma registry data are by definition incomplete, combining data sources is essential. Local law enforcement data are an important potential source for studying city-level firearm injury. Level of evidence Level III, epidemiological.

Plasma receptor interacting protein kinase-3 levels are associated with acute respiratory distress syndrome in sepsis and trauma: a cohort study. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2019; 23:235. [PMID: 31253195 PMCID: PMC6599265 DOI: 10.1186/s13054-019-2482-x] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/20/2018] [Accepted: 05/19/2019] [Indexed: 02/06/2023]
Abstract
Background Necroptosis, a form of programmed cell death mediated by receptor interacting serine/threonine-protein kinase-3 (RIPK3), is implicated in murine models of acute respiratory distress syndrome (ARDS). We hypothesized that plasma RIPK3 concentrations in sepsis and trauma would be associated with ARDS development and that plasma RIPK3 would reflect changes in lung tissue RIPK3 in a murine model of systemic inflammation. Methods We utilized prospective cohort studies of critically ill sepsis (n = 120) and trauma (n = 180) patients and measured plasma RIPK3 at presentation and 48 h. Patients were followed for 6 days for ARDS by the Berlin definition. We used multivariable logistic regression to determine the association of plasma RIPK3 with ARDS in each cohort, adjusting for confounders. In mice, we determined whether plasma and lung tissue RIPK3 levels rise concomitantly 4 h after injection with lipopolysaccharide and ZVAD-FMK, an apoptosis inhibitor. Results The change in plasma RIPK3 from presentation to 48 h (ΔRIPK3) was associated with ARDS in sepsis (OR 1.30, 95% CI 1.03–1.63, per ½ standard deviation) and trauma (OR 1.79, 95% CI 1.33–2.40). This association was not evident for presentation RIPK3 levels. Secondary analyses showed similar findings for the association of ΔRIPK3 with acute kidney injury and 30-day mortality. Mice injected with lipopolysaccharide and ZVAD-FMK had significantly higher plasma (p < 0.001) and lung (p = 0.005) RIPK3 than control mice. Conclusions The change in plasma RIPK3 from presentation to 48 h in both sepsis and trauma patients is independently associated with ARDS, and plasma RIPK3 may reflect RIPK3 activity in lung tissue.

Abstract
BACKGROUND Training in Acute Care Surgery (ACS) is an integral component of general surgery residency and serves as a critical base experience for the added educational qualifications of fellowship. How this training varies between programs is not well characterized. We sought to describe the variation in clinical exposure between residencies in a sample of residents applying to an ACS fellowship. We hypothesized that applicants have significant variations in clinical exposure as well as unique and specific expectations for educational experiences. MATERIALS AND METHODS We offered an anonymous 82-question survey focused on residency clinical exposure and self-perceived confidence in key areas of ACS training, as well as fellowship training and career expectations to all applicants interviewed at a single trauma, critical care, and emergency surgery fellowship program. Responses were assessed via absolute numbers and confidence via a 5-point Likert scale; data are reported using descriptive statistics and linear regression models. RESULTS Forty-two interviewing applicants completed the survey, for a 96% response rate. Applicants reported heterogeneous levels of comfort across most ACS domains. There was good correlation between experience and comfort in most procedural areas. During fellowship training, respondents placed highest priority on operative experience, with 43% rating this as their highest priority, followed by penetrating trauma experience (33%). CONCLUSIONS We found significant variations in both experience and comfort within key ACS domains among fellowship applicants. Despite training variability, there was good correlation between experience and self-reported comfort. Collaboration between residency and fellowship governing bodies may help address areas of limited exposure before entry into clinical practice.

Abstract
In April 2017, the American Association for the Surgery of Trauma (AAST) asked the AAST Patient Assessment Committee to undertake a gap analysis for published clinical practice guidelines in emergency general surgery (EGS). Committee members performed literature searches to catalogue published guidelines for common EGS diseases and also to identify gaps in the literature where guidelines could be created. For five of the most common EGS conditions, acute appendicitis, acute cholecystitis, acute diverticulitis, acute pancreatitis, and small bowel obstruction, we found multiple well-referenced guidelines published by leading professional organizations. We have summarized guideline recommendations for each of these disease states stratified by the AAST EGS anatomic severity score based on these published consensus guidelines. These summaries could be used to help inform evidence-based clinical decision-making, but are intended to be flexible and updatable in real time as further research emerges. Comprehensive guidelines were available for all of the diseases queried and identified gaps most commonly represented areas lacking a solid evidence base. These are therefore areas where further research is needed.

Abstract
BACKGROUND Resuscitative endovascular balloon occlusion of the aorta (REBOA) has emerged as a bridge to definitive hemostasis in select patients with noncompressible torso hemorrhage. The number of patients who might benefit from this procedure, however, remains incompletely defined. We hypothesized that we could quantify the number of patients presenting to our center over a 2-year period who may have benefited from REBOA. METHODS All patients presenting to our trauma center from 2014 to 2015 were included. Potential REBOA patients were identified based on anatomic injuries. We used ICD-9 codes to identify REBOA-amenable injury patterns and physiology. We excluded patients with injuries contraindicating REBOA. We then used chart review by two REBOA-experienced independent reviewers to assess each potential REBOA candidate, evaluate the accuracy of our algorithm, and to identify a cohort of confirmed REBOA candidates. RESULTS Four thousand eight hundred eighteen patients were included of which 666 had injuries potentially amenable to REBOA. Three hundred thirty-five patients were hemodynamically unstable, and 309 patients had contraindications to REBOA. Sixty-four patients had both injury patterns and physiology amenable to REBOA with no contraindications, and these patients were identified as potential REBOA candidates. Of these, detailed independent two physician chart review identified 29 patients (45%) as confirmed REBOA candidates (interrater reliability kappa = 0.94, P < 0.001). CONCLUSIONS Our database query identified patients with indications for REBOA but overestimated the number of REBOA candidates. To accurately quantify the REBOA candidate population at a given center, an algorithm to identify potential patients should be combined with chart review. STUDY TYPE Therapeutic study, level V.

Abstract
INTRODUCTION Emergency department thoracotomy (EDT) must be rapid and well-executed. Currently there are no defined benchmarks for EDT procedural milestones. We hypothesized that trauma video review (TVR) can be used to define the 'normative EDT' and generate procedural benchmarks. As a secondary aim, we hypothesized that data collected by TVR would have less missingness and bias than data collected by review of the Electronic Medical Record (EMR). METHODS We used continuously recording video to review all EDTs performed at our centre during the study period. Using skin incision as start time, we defined four procedural milestones for EDT: 1. Decompression of the right chest (tube thoracostomy, finger thoracostomy, or clamshell thoracotomy with transverse sternotomy performed in conjunction with left anterolateral thoracotomy) 2. Retractor deployment 3. Pericardiotomy 4. Aortic Cross-clamp. EDTs with any milestone time ≥ 75th percentile of time or during which a milestone was omitted were identified as outliers. We compared rates of missingness in data collected by TVR and EMR using McNemar's test. RESULTS 44 EDTs were included from the study period. Patients had a median age of 30 [IQR 25-44] and were predominantly African-American (95%) males (93%) with penetrating trauma (95%). From skin incision, median times in minutes to milestones were as follows: right chest decompression: 2.11 [IQR 0.68-2.83], retractor deployment 1.35 [IQR 0.96-1.85], pericardiotomy 2.35 [IQR 1.85-3.75], aortic cross-clamp 3.71 [IQR 2.83-5.77]. In total, 28/44 (64%) of EDTs were either high outliers for one or more benchmarks or had milestones that were omitted. For all milestones, rates of missingness for TVR data were lower than EMR data (p < 0.001). CONCLUSIONS Video review can be used to define normative times for the procedural milestones of EDT. Steps exceeding the 75th percentile of time were common, with over half of EDTs having at least one milestone as an outlier. Data quality is higher using TVR compared to EMR collection. Future work should seek to determine if minimizing procedural technical outliers improves patient outcomes.

Abstract
OBJECTIVES We determined the impact of including race, ethnicity, and poverty in risk adjustment models for emergency care-sensitive conditions mortality that could be used for hospital pay-for-performance initiatives. We hypothesized that adjusting for race, ethnicity, and poverty would bolster rankings for hospitals that cared for a disproportionate share of nonwhite, Hispanic, or poor patients. METHODS We performed a cross-sectional analysis of patients admitted from the emergency department to 157 hospitals in Pennsylvania with trauma, sepsis, stroke, cardiac arrest, and ST-elevation myocardial infarction. We used multivariable logistic regression models to predict in-hospital mortality. We determined the predictive accuracy of adding patient race and ethnicity (dichotomized as non-Hispanic white vs. all other Hispanic or nonwhite patients) and poverty (uninsured, on Medicaid, or lowest income quartile zip code vs. all others) to other patient-level covariates. We then ranked each hospital on observed-to-expected mortality, with and without race, ethnicity, and poverty in the model, and examined characteristics of hospitals with large changes between models. RESULTS The overall mortality rate among 170,750 inpatients was 6.9%. Mortality was significantly higher for nonwhite and Hispanic patients (adjusted odds ratio [aOR] = 1.27, 95% confidence interval [CI] = 1.19-1.36) and poor patients (aOR = 1.21, 95% CI = 1.12-1.31). Adding race, ethnicity, and poverty to the risk adjustment model resulted in a small increase in C-statistic (0.8260 to 0.8265, p = 0.002). No hospitals moved into or out of the highest-performing decile when adjustment for race, ethnicity, and poverty was added, but the three hospitals that moved out of the lowest-performing decile, relative to other hospitals, had significantly more nonwhite and Hispanic patients (68% vs. 11%, p < 0.001) and poor patients (56% vs. 10%, p < 0.001). CONCLUSIONS Sociodemographic risk adjustment of emergency care-sensitive mortality improves apparent performance of some hospitals treating a large number of nonwhite, Hispanic, or poor patients. This may help these hospitals avoid financial penalties in pay-for-performance programs.
