An assessment of nationwide trends in emergency department (ED) resuscitative endovascular balloon occlusion of the aorta (REBOA) use - A trauma quality improvement program registry analysis.

BACKGROUND: Use of resuscitative endovascular balloon occlusion of the aorta (REBOA) for temporary hemorrhage control in severe non-compressible torso trauma remains controversial, with limited data on patient selection and outcomes. This study aims to analyze the nationwide trends of its use in the emergency department (EDs). METHODS: A retrospective analysis of the American College of Surgeons Trauma Quality Improvement Program (ACS-TQIP) from 2017 to 2022 was performed, focusing on REBOA placements in EDs. RESULTS: The analysis included 3398 REBOA procedures. Majority patients were male (76 â€‹%) with a median age of 40 years (27-58) and injury severity score of 20 (20-41). The most common mechanism was collision (64 â€‹%), with emergency surgeries most frequently performed for pelvic trauma (14 â€‹%). Level 1 trauma centers performed 82 â€‹% of these procedures, with consistent low annual utilization (<200 facilities). Survival rates were 85 â€‹% at 1-h post-placement, decreasing significantly to 42 â€‹% by discharge. CONCLUSIONS: REBOA usage in remains limited but steady, primarily occurring at level 1 trauma center EDs. While short-term survival rates are favorable, they drop significantly by the time of discharge.

Managing career transitions in the profession of acute care surgery.

Career shifts are a naturally occurring part of the trauma and acute care surgeon's profession. These transitions may occur at various timepoints throughout a surgeon's career and each has their own specific challenges. Finding a good fit for your first job is critical for ensuring success as an early career surgeon. Equally, understanding how to navigate promotions or a change in job location mid-career can be fraught with uncertainty. As one progresses in their career, knowing when to take on a leadership position is oftentimes difficult as it may mean a change in priorities. Finally, navigating your path towards a fulfilling retirement is a complex discussion that is different for each surgeon. The American Association for the Surgery of Trauma (AAST) convened an expert panel of acute care surgeons in a virtual grand rounds session in August 2023 to address the aforementioned career transitions and highlight strategies for successfully navigating each shift. This was a collaboration between the AAST Associate Member Council (consisting of surgical resident, fellow and junior faculty members), the AAST Military Liaison Committee and the AAST Healthcare Economics Committee. Led by two moderators, the panel consisted of early, mid-career and senior surgeons, and recommendations are summarized below and in figure 1.

A novel preoperative score to predict severe acute cholecystitis.

BACKGROUND: In a large multicenter trial, The Parkland Grading Scale (PGS) for acute cholecystitis outperformed other grading scales and has a positive correlation with complications but is limited in its inability to preoperatively predict high-grade cholecystitis. We sought to identify preoperative variables predictive of high-grade cholecystitis (PGS 4 or 5). METHODS: In a six-month period, patients undergoing cholecystectomy at a single institution with prospectively graded PGS were analyzed. Stepwise logistic regression models were constructed to predict high-grade cholecystitis. The relative weight of the variables was used to derive a novel score, the Severe Acute Cholecystitis Score (SACS). This score was compared with the Emergency Surgery Acuity Score(ESS), American Association for the Surgery of Trauma (AAST) preoperative score and Tokyo Guidelines (TG) for their ability to predict high-grade cholecystitis. Severe Acute Cholecystitis Score was then validated using the database from the AAST multicenter validation of the grading scale for acute cholecystitis. RESULTS: Of the 575 patients that underwent cholecystectomy, 172 (29.9%) were classified as high-grade. The stepwise logistic regression modeling identified seven independent predictors of high-grade cholecystitis. From these variables, the SACS was derived. Scores ranged from 0 to 9 points with a C statistic of 0.76, outperforming the ESS ( C statistic of 0.60), AAST (0.53), and TG (0.70) ( p < 0.001). Using a cutoff of 4 or more on the SACS correctly identifies 76.2% of cases with a specificity of 91.3% and a sensitivity of 40.7%. In the multicenter database, there were 464 patients with a prospectively collected PGS. The C statistic for SACS was 0.74. Using the same cutoff of 4, SACS correctly identifies 71.6% of cases with a specificity of 83.8% and a sensitivity of 52.2%. CONCLUSION: The Severe Acute Cholecystitis Score can preoperatively predict high-grade cholecystitis and may be useful for counseling patients and assisting in surgical decision making. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level III.

Futility in acute care surgery: first do no harm.

The consequences of the delivery of futile or potentially ineffective medical care and interventions are devastating on the healthcare system, our patients and their families, and healthcare providers. In emergency situations in particular, determining if escalating invasive interventions will benefit a frail and/or severely critically ill patient can be exceedingly difficult. In this review, our objective is to define the problem of potentially ineffective care within the specialty of acute care surgery and describe strategies for improving the care of our patients in these difficult situations.

Using Trauma Video Review to Assess EMS Handoff and Trauma Team Non-Technical Skills.

OBJECTIVE: Handoffs by emergency medical services (EMS) personnel suffer from poor structure, inattention, and interruptions. The relationship between the quality of EMS communication and the non-technical performance of trauma teams remains unknown. METHODS: We analyzed 3 months of trauma resuscitation videos (highest acuity activations or patients with an Injury Severity Score [ISS] of ≥15). Handoffs were scored using the mechanism-injury-signs-treatment (MIST) framework for completeness (0-20), efficiency (category jumps), interruptions, and timeliness. Trauma team non-technical performance was scored using the Trauma Non-Technical Skills (T-NOTECHS) scale (5-15). RESULTS: We analyzed 99 videos. Handoffs lasted a median of 62 seconds [IQR: 43-74], scored 11 [10-13] for completeness, and had 2 [1-3] interruptions. Most interruptions were verbal (85.2%) and caused by the trauma team (64.9%). Most handoffs (92%) were efficient with 2 or fewer jumps. Patient transfer during handoff occurred in 53.5% of the videos; EMS providers giving handoff helped transfer in 69.8% of the Primary surveys began during handoff in 42.4% of the videos. Resuscitation teams who scored in the top-quartile on the T-NOTECHS (>11) had higher MIST scores than teams in lower quartiles (13 [11.25-14.75] vs. 11 [10-13]; p < .01). There were no significant differences in ISS, efficiency, timeliness, or interruptions between top- and lower-quartile groups. CONCLUSIONS: There is a relationship between EMS MIST completeness and high performance of non-technical skill by trauma teams. Trauma video review (TVR) can help identify modifiable behaviors to improve EMS handoff and resuscitation efforts and therefore trauma team performance.

How Do Hospital-Specific Data Dictionaries Impact Competency Level With Data Collection: A National Survey.

BACKGROUND: Trauma registry staff are tasked with high-quality data collection to support program requirements. Hospital-specific data dictionaries are increasingly used to ensure accurate data collection, yet it is unknown how such a resource impacts a trauma registry team's competency with data collection. OBJECTIVE: This study sought to explore whether having a hospital-specific data dictionary affected trauma service team members' self-reported competency level with abstracting required and nonrequired data elements. METHODS: This study used an anonymous, cross-sectional survey distributed (July 2020 to September 2020) by the Society of Trauma Nurses, the American College of Surgeons, and the Trauma System News outlets to trauma registrars, trauma nurse coordinators, clinical quality specialists, program managers, program directors, and trauma research personnel. A 26-question survey was designed using a visual sliding scale from 0 to 100 to measure self-reported competence and associated variables. RESULTS: A total of 881 respondents completed the survey from at least 495 centers. Six hundred ninety-six (79.0%) respondents were from Level I or Level II programs. Several factors were associated with team members feeling highly competent in collecting data for various reporting requirements, including the level of trauma center verification, tenure working in trauma services, and the presence of a hospital-specific data dictionary. CONCLUSION: Trauma centers should consider establishing a hospital-specific data dictionary as they are associated with higher registry staff competence working with trauma registry data.

Trauma Registry Data Collection Practices and the Impact of Hospital Data Dictionaries: A National Survey.

BACKGROUND: Trauma programs are required to collect a uniform set of trauma variables and submit data to regional, state, and or national registries. Programs may also collect unique data elements to support hospital-specific initiatives. OBJECTIVE: This study explored what additional data elements are being collected by U.S. trauma programs and the impact of having a hospital-specific data dictionary. METHODS: An anonymous, cross-sectional survey exploring what additional data are being collected, and the impact of having a hospital-specific data dictionary, was distributed by the Society of Trauma Nurses, Trauma System News, and the American College of Surgeons. The survey was open from July 2020 to September, 2020. RESULTS: There were 693 respondents from approximately 368 Level I/II trauma programs. The estimated trauma center response rate was 59.4% (n = 368/620). Level I programs had a higher response rate than Level II programs (66.9% and 53.4%, respectively).In our sample, 85.5% of responding centers collect additional data. The most common additional data collected at Level I/II programs concerned quality improvement initiatives (70.3% and 66.1%, respectively). Other commonly collected data pertained to deaths (60.6%) and complications (50.3%).Only 43% of responding centers (n = 161/368) have a hospital-specific data dictionary. Hospitals that collect additional data were more likely to have such a resource compared with those that do not (n = 147/315, 46.7% vs. n = 14/53, 26.4%, p = .01). CONCLUSION: Most trauma programs collect data outside required fields. Fewer than half define these data in a data dictionary. Centers should consider establishing a data dictionary to define data collected.

Provider Perception of Time During Trauma Resuscitation: A Prospective Quantitative Trauma Video Review Analysis.

INTRODUCTION: Delays in transition to the next phase of care result in increased mortality. Prehospital literature suggests emergency medical service technicians underestimate transport times by as much as 20%. What remains unknown is clinician perception of time during the trauma resuscitation. We sought to determine if clinicians have an altered perception of time. We hypothesized that clinicians underestimate time, resulting in delay of care. METHODS: Clinicians at a large level 1 trauma center completed a post-trauma activation survey on the perceived elapsed time to complete three specific resuscitation endpoints. The primary study endpoint was the time to the next phase of care, defined as leaving the trauma bay to go to the operating room, interventional radiology, computerized tomography or time of death. The data from the surveys were linked and compared with recorded videos of the resuscitations. The difference in perceived versus actual time, along with confounding variables, was used to assess the impact of perception of time on the time to the next phase of care using a stepwise multivariate linear model. RESULTS: There were 284 complete surveys and videos, culminating in 543 time points. The median perceived versus actual time (minutes [interquartile range]) to the next phase of care was 20 [10-25] versus 26 [19-40] (P < 0.001). Overall, clinicians underestimated time by 28%, such that if the resuscitation lasted 20 min, the clinician's perception was that 14.4 min elapsed. Differences in the perceived versus actual time in the procedure group impacted time to the next phase of care (P = 0.01). CONCLUSIONS: Clinicians have significant gaps in the perception of time during trauma resuscitations. This misperception occurs during procedures and correlates with an increase in the length of time to the next phase of care.

Parkland Trauma Index of Mortality: Real-Time Predictive Model for Trauma Patients.

OBJECTIVE: Vital signs and laboratory values are used to guide decisions to use damage control techniques in lieu of early definitive fracture fixation. Previous models attempted to predict mortality risk but have limited utility. There is a need for a dynamic model that captures evolving physiologic changes during a trauma patient's hospital course. METHODS: The Parkland Trauma Index of Mortality (PTIM) is a machine learning algorithm that uses electronic medical record data to predict mortality within 48 hours during the first 3 days of hospitalization. It updates every hour, recalculating as physiology changes. The model was developed using 1935 trauma patient encounters from 2009 to 2014 and validated on 516 patient encounters from 2015 to 2016. Model performance was evaluated statistically. Data were collected retrospectively on its performance after 1 year of clinical use. RESULTS: In the validation data set, PTIM accurately predicted 52 of the sixty-three 12-hour time intervals within 48 hours of mortality, for sensitivity of 82.5% [95% confidence interval (CI), 73.1%-91.9%]. The specificity was 93.6% (95% CI, 92.5%-94.8%), and the positive predictive value (PPV) was 32.5% (95% CI, 25.2%-39.7%). PTIM predicted survival for 1608 time intervals and was incorrect only 11 times, yielding a negative predictive value of 99.3% (95% CI, 98.9%-99.7%). The area under the curve of the receiver operating characteristic curve was 0.94.During the first year of clinical use, when used in 776 patients, the last PTIM score accurately predicted 20 of the twenty-three 12-hour time intervals within 48 hours of mortality, for sensitivity of 86.9% (95% CI, 73%-100%). The specificity was 94.7% (95% CI, 93%-96%), and the positive predictive value was 33.3% (95% CI, 21.4%-45%). The model predicted survival for 716 time intervals and was incorrect 3 times, yielding a negative predictive value of 99.6% (95% CI, 99.1%-100%). The area under the curve of the receiver operating characteristic curve was 0.97. CONCLUSIONS: By adapting with the patient's physiologic response to trauma and relying on electronic medical record data alone, the PTIM overcomes many of the limitations of previous models. It may help inform decision-making for trauma patients early in their hospitalization. LEVEL OF EVIDENCE: Prognostic Level I.

Does Gender Matter: A Multi-Institutional Analysis of Viscoelastic Profiles for 1565 Trauma Patients With Severe Hemorrhage.

BACKGROUND: Viscoelastic tests including thromboelastography (TEG) and rotational thromboelastometry (ROTEM) are being used in patients with severe hemorrhage at trauma centers to guide resuscitation. Several recent studies demonstrated hypercoagulability in female trauma patients that was associated with a survival advantage. The objective of our study was to elucidate the effects of gender differences in TEG/ROTEM values on survival in trauma patients with severe hemorrhage. METHODS: A retrospective review of consecutive adult patients receiving massive transfusion protocol (MTP) at 7 Level I trauma centers was performed from 2013 to 2018. Data were stratified by gender and then further examined by TEG or ROTEM parameters. Results were analyzed using univariate and multi-variate analyses. RESULTS: A total of 1565 patients were included with 70.9% male gender (n = 1110/1565). Female trauma patients were older than male patients (43.5 ± .9 vs 41.1 ± .6 years, P = .01). On TEG, females had longer reaction times (6.1 ± .9 min vs 4.8 ± .2 min, P = .03), increased alpha angle (68.6 ± .8 vs 65.7 ± .4, P < .001), and higher maximum amplitude (59.8 ± .8 vs 56.3 ± .4, P < .001). On ROTEM, females had significantly longer clot time (99.2 ± 13.7 vs 75.1 ± 2.6 sec, P = .09) and clot formation time (153.6 ± 10.6 sec vs 106.9 ± 3.8 sec, P < .001). When comparing by gender, no difference for in-hospital mortality was found for patients in the TEG or ROTEM group (P > .05). Multivariate analysis showed no survival difference for female patients (OR 1.11, 95% CI .83-1.50, P = .48). CONCLUSIONS: Although a difference between male and females was found on TEG/ROTEM for certain clotting parameters, no difference in mortality was observed. Prospective multi-institutional studies are needed.

Defining adverse events during trauma resuscitation: a modified RAND Delphi study.

BACKGROUND: The majority of preventable adverse event (AEs) in trauma care occur during the initial phase of resuscitation, often within the trauma bay. However, there is significant heterogeneity in reporting these AEs that limits performance comparisons between hospitals and trauma systems. The objective of this study was to create a taxonomy of AEs that occur during trauma resuscitation and a corresponding classification system to assign a degree of harm. METHODS: This study used a modified RAND Delphi methodology to establish a taxonomy of AEs in trauma and a degree of harm classification system. A systematic review informed the preliminary list of AEs. An interdisciplinary panel of 22 trauma experts rated these AEs through two rounds of online surveys and a final consensus meeting. Consensus was defined as 80% for each AE and the final checklist. RESULTS: The Delphi panel consisted of 22 multidisciplinary trauma experts. A list of 57 evidence-informed AEs was revised and expanded during the modified Delphi process into a finalized list of 67 AEs. Each AE was classified based on degree of harm on a scale from I (no harm) to V (death). DISCUSSION: This study developed a taxonomy of 67 AEs that occur during the initial phases of a trauma resuscitation with a corresponding degree of harm classification. This taxonomy serves to support a standardized evaluation of trauma care between centers and regions. LEVEL OF EVIDENCE: Level 5.

Guidelines for the performance of minimally invasive splenectomy.

BACKGROUND: Minimally invasive splenectomy (MIS) is increasingly favored for the treatment of benign and malignant diseases of the spleen over open access approaches. While many studies cite the superiority of MIS in terms of decreased morbidity and length of stay over a traditional open approach, the comparative effectiveness of specific technical and peri-operative approaches to MIS is unclear. OBJECTIVE: To develop evidence-based guidelines that support clinicians, patients, and others in decisions on the peri-operative performance of MIS. METHODS: A guidelines committee panel of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) including methodologists used the Grading of Recommendations Assessment, Development and Evaluation approach to grade the certainty of evidence and formulate recommendations. RESULTS: Informed by a systematic review of the evidence, the panel agreed on eight recommendations for the peri-operative performance of MIS for adults and children in elective situations addressing six key questions. CONCLUSIONS: Conditional recommendations were made in favor of lateral positioning for non-hematologic disease, intra-operative platelet administration for patients with idiopathic thrombocytopenic purpura instead of preoperative administration, and the use of mechanical devices to control the splenic hilum. Further, a conditional recommendation was made against routine intra-operative drain placement.

Pitfalls in Study Interpretation.

Background: The goal of a randomized or observational study is to develop an unbiased and reliable answer to a therapeutic question. However, there are multiple pitfalls in the reporting and interpretation of data that can compromise our ability to evaluate the pragmatism and the effectiveness of the intervention being studied. Researchers must be conscious of these biases when designing their studies, just as readers must be aware of these potential pitfalls when interpreting results. Results: The purpose of this review is to highlight some of the more common sources of bias in clinical research, including internal and external validity, type 1 and type 2 error, reporting of secondary outcomes, the use of subgroup analyses, and multiple comparisons. This article also discusses potential solutions to these issues, including using the fragility index to understand the robustness of study conclusions, and generating an E value to determine the degree of unmeasured confounding in a study. Conclusions: With an understanding of these pitfalls, readers can critically review scientific literature and ascertain the validity of the conclusions.

Safety of Erector Spinae Plane Blocks in Patients With Chest Wall Trauma on Venous Thromboembolism Prophylaxis.

BACKGROUND: Current guidelines for severe rib fractures recommend neuraxial blockade in addition to multimodal pain therapies. While the guidelines for venous thromboembolism prevention recommend chemoprophylaxis, these medications must be held for neuraxial blockade placement. Erector spinae plane block (ESPB) is a newly described block for thoracic pain control. Advantages include its quick learning curve and potential for less bleeding complications. We describe the use of ESPB for rib fractures in patients on chemoprophylaxis. We hypothesize that ESPB can be performed in this patient population without holding chemoprophylaxis. MATERIALS AND METHODS: This was a retrospective observational cohort study of a level 1 trauma center from 9/2016 to 12/2018. All patients with trauma with rib fractures undergoing neuraxial blockade or ESPB were included. Demographics, chemoprophylaxis and anticoagulation regimens, outcomes, and complications were collected. RESULTS: Nine hundred sixty-four patients with rib fracture(s) were admitted. Of these, 73 had a pain management consult. Thirteen had epidural catheters and 25 had ESPBs placed. There was no difference in demographics, injury patterns, bleeding complications, or venous thromboembolism rates among the groups. Patients with ESPB were less likely to have a dose of chemoprophylaxis held because of placement of a catheter (25% versus 100%, P < 0.00001). Three patients with ESPB were on oral anticoagulation on admission, and two were able to continue their regimen during placement. CONCLUSIONS: ESPB can be safely placed in patients on chemoprophylaxis. It should be considered over traditional blocks in patients with blunt chest wall trauma because of its technical ease and ability to be performed with chemoprophylaxis.

Fast track pathway provides safe, value based care on busy acute care surgery service.

BACKGROUND: Fast track (FT) pathways have been adopted across a multitude of elective surgeries but have been slow to be adopted into the acute care surgery realm. We hypothesized that an FT pathway for acute cholecystitis patients would decrease patient length of stay and resource utilization. METHODS: All patients at two hospitals, one with an FT pathway and one with a traditional pathway, who underwent an urgent laparoscopic cholecystectomy for acute cholecystitis between May 1, 2019, and October 31, 2019, were queried using CPT codes. Exclusion criteria were conversion to open or partial cholecystectomy. Retrospective chart review was used to gather demographics, operative, hospital course, and outcomes. Time to operating room, hospital length of stay, and resource utilization were the primary outcomes. RESULTS: There was a total of 479 urgent laparoscopic cholecystectomies performed, 430 (89.8%) were performed under the FT pathway. The median (interquartile range [IQR]) time to the operating room was not different: 14.1 hours (IQR, 8.3-29.0 hours) for FT and 18.5 hours (IQR, 11.9-25.9 hours) for traditional (p = 0.316). However, the median length of stay was shorter by 15.9 hours in the FT cohort (22.6 hours; IQR, 14.2-40.4 hours vs. 38.5 hours; IQR, 28.3-56.3 hours; p < 0.001). Under the FT pathway, 33.0% of patients were admitted to the hospital and 75.6% were discharged from the postanesthesia care unit, compared with 91.8% and 12.2% on the traditional pathway (both p < 0.001). There were 59.6% of the FT patients that received a phone call follow up, as opposed to 100% of the traditional patients having clinic follow up (p < 0.001). The emergency department bounce back rate, readmission rates, and complication rates were similar (p > 0.2 for all). On multivariate analysis, having a FT pathway was an independent predictor of discharge within 24 hours of surgical consultation (odds ratio, 7.65; 95% confidence interval< 2.90-20.15; p < 0.001). CONCLUSION: Use of a FT program for patients with acute cholecystitis has a significant positive impact on resource utilization without compromise of clinical outcomes. LEVEL OF EVIDENCE: Therapeutic/care management, level IV.

Initial clinical experience with the Quantra QStat System in adult trauma patients.

BACKGROUND: Whole blood viscoelastic testing (VET) devices are routinely used in a variety of clinical settings to assess hemostasis. The Quantra QStat System is a cartridge-based point of care VET device that measures changes in clot stiffness during coagulation and fibrinolysis using ultrasound detection of resonance. The objective of this study was to assess the ability of the Quantra QStat System to detect coagulopathies in trauma patients. METHODS: A multicenter observational study was conducted on adult subjects at two level 1 trauma centers. For each subject, whole blood samples were drawn upon arrival to the emergency department and again, in some cases, after administration of blood products and/or antifibrinolytics. Samples were analyzed on the Quantra in parallel to ROTEM delta. The QStat cartridge provides measures of Clot Time (CT), Clot Stiffness (CS), Fibrinogen and Platelet Contributions to clot stiffness (FCS and PCS), and Clot Stability to Lysis (CSL). Data analyses included linear regression of Quantra and ROTEM parameters and an assessment of the concordance of the two devices for the assessment of hyperfibrinolysis. RESULTS: A total of 56 patients were analyzed. 42% of samples had a low QStat CS value suggestive of an hypocoagulable state. The low stiffness values could be attributed to either low PCS, FCS or combination. Additionally, 13% of samples showed evidence of hyperfibrinolysis based on the QStat CSL parameter. Samples analyzed with ROTEM assays showed a lower prevalence of low CS and hyperfibrinolysis based on EXTEM and FIBTEM results. The correlation of CS, FCS and CT versus equivalent ROTEM parameters was strong with r-values of 0.83, 0.79 and 0.79, respectively. DISCUSSION: This first clinical experience with the Quantra in trauma patients showed that the QStat Cartridge was strongly correlated with ROTEM parameters and that it could detect coagulopathies associated with critical bleeding. LEVEL OF EVIDENCE: Diagnostic test, Level II.
