Few studies have investigated risk factors for recurrence of blunt traumatic abdominal wall hernias (TAWH).Twenty trauma centers identified repaired TAWH from January 2012 to December 2018. Logistic regression was used to investigate risk factors for recurrence.TAWH were repaired in 175 patients with 21 (12.0%) known recurrences. No difference was found in location, defect size, or median time to repair between the recurrence and non-recurrence groups. Mesh use was not protective of recurrence. Female sex, injury severity score (ISS), emergency laparotomy (EL), and bowel resection were associated with hernia recurrence. Bowel resection remained significant in a multivariable model.Female sex, ISS, EL, and bowel resection were identified as risk factors for hernia recurrence. Mesh use and time to repair were not associated with recurrence. Surgeons should be mindful of these risk factors but could attempt acute repair in the setting of appropriate physiologic parameters.

Introduction Surgery residents have high burnout rates and mistreatment occurs during training. We hypothesized that residents who reported mistreatment would be more likely to experience burnout. Methods A multi-institutional observational study asked residents to complete the Maslach Burnout Inventory and to rate how often they experienced mistreatment. Scores in the high-risk range for emotional exhaustion or depersonalization were classified as burnout. Associations between mistreatment behaviors, program, sex, post graduate year(PGY), and clinical status were measured by Spearman's correlation, linear regression, and logistic regression. Results We invited 398 residents to participate; 180 responded(45%). 52%(n = 93) were female, there was an even distribution among PGY, and seven programs were represented. Almost half of the cohort (48%) reported high risk for burnout and 68% reported experiencing mistreatment. Mistreatment by senior physician team members were correlated with EE(rho = 0.184,p = 0.016) and DP(rho = 0.181,p = 0.016). Conclusion While overall burnout was not significantly associated with mistreatment behaviors, both burnout and mistreatment were commonly reported.

BACKGROUND Blunt traumatic abdominal wall hernias (TAWH) occur in approximately 15,000 patients per year. Limited data are available to guide the timing of surgical intervention or the feasibility of nonoperative management. METHODS A retrospective study of patients presenting with blunt TAWH from January 2012 through December 2018 was conducted. Patient demographic, surgical, and outcomes data were collected from 20 institutions through the Western Trauma Association Multicenter Trials Committee. RESULTS Two hundred and eighty-one patients with TAWH were identified. One hundred and seventy-six (62.6%) patients underwent operative hernia repair, and 105 (37.4%) patients underwent nonoperative management. Of those undergoing surgical intervention, 157 (89.3%) were repaired during the index hospitalization, and 19 (10.7%) underwent delayed repair. Bowel injury was identified in 95 (33.8%) patients with the majority occurring with rectus and flank hernias (82.1%) as compared with lumbar hernias (15.8%). Overall hernia recurrence rate was 12.0% (n = 21). Nonoperative patients had a higher Injury Severity Score (24.4 vs. 19.4, p = 0.010), head Abbreviated Injury Scale score (1.1 vs. 0.6, p = 0.006), and mortality rate (11.4% vs. 4.0%, p = 0.031). Patients who underwent late repair had lower rates of primary fascial repair (46.4% vs. 77.1%, p = 0.012) and higher rates of mesh use (78.9% vs. 32.5%, p < 0.001). Recurrence rate was not statistically different between the late and early repair groups (15.8% vs. 11.5%, p = 0.869). CONCLUSION This report is the largest series and first multicenter study to investigate TAWHs. Bowel injury was identified in over 30% of TAWH cases indicating a significant need for immediate laparotomy. In other cases, operative management may be deferred in specific patients with other life-threatening injuries, or in stable patients with concern for bowel injury. Hernia recurrence was not different between the late and early repair groups. LEVEL OF EVIDENCE Therapeutic/care management, Level IV.

Background Deranged physiology in trauma complicates the clinical identification of sepsis, resulting in overscreening for bacteremia. No clinical signs or biomarkers accurately diagnose sepsis in this population. Our objective was to evaluate the accuracy of the current criteria used to prompt screening for bacteremia in trauma patients and determine independent predictors of bacteremia. Materials and Methods Adult trauma patients admitted to our level I academic trauma center who had blood cultures (BCs) drawn were identified. Those with positive BCs were compared to those with negative or false positive BCs. False positive was defined as a BC deemed contaminated and not treated at the discretion of the attending physician. Results Over a 2-year period, 366 trauma patients had BCs drawn. After excluding surveillance cultures (those drawn to demonstrate bacteremia clearance), 492 unique BC sets were evaluated; 104 (21.1%) BC sets were positive; 30 (28.8%) of these were falsely positive, resulting in a true-positive rate of 15% in the screened population. Univariate analysis suggested temperature and heart rate were associated with positive BC, while multivariable analysis found only the presence of a central line and lactic acid to be predictive. Procalcitonin (PCT) was poorly predictive, with a positive predictive value of 18% and a negative predictive value of 91%. Conclusion Current tools for identifying bacteremia in trauma patients result in overscreening. PCT may have a limited role as a negative predictor for bacteremia. Given that false-positive BCs have negative patient and economic consequences, future study should focus on development of alternative screening modalities.

Objective After COVID-19 rendered in-person meetings for national societies impossible in the spring of 2020, the leadership of the Association of Program Directors in Surgery (APDS) innovated via a virtual format in order to hold its national meeting. Design APDS leadership pre-emptively considered factors that would be important to attendees including cost, value, time, professional commitments, education, sharing of relevant and current information, and networking. Setting The meeting was conducted using a variety of virtual formats including a web portal for entry, pre-ecorded poster and oral presentations on the APDS website, interactive panels via a web conferencing platform, and livestreaming. Participants There were 298 registrants for the national meeting of the APDS, and 59 participants in the New Program Directors Workshop. The registrants and participants comprised medical students, residents, associate program directors, program directors, and others involved in surgical education nationally. Results There was no significant difference detected for high levels of participant satisfaction between 2019 and 2020 for the following items: overall program rating, topics and content meeting stated objectives, relevant content to educational needs, educational format conducive to learning, and agreement that the program will improve competence, performance, communication skills, patient outcomes, or processes of care/healthcare system performance. Conclusions A virtual format for a national society meeting can provide education, engagement, and community, and the lessons learned by the APDS in the process can be used by other societies for utilization and further improvement.

Surgical residents have been shown to experience high rates of burnout. Whether this is influenced predominately by intrinsic characteristics, external factors, or is multifactorial has not been well studied. The aim of this study was to explore the relationship between these elements and burnout. We hypothesized that residents with higher emotional intelligence scores, greater resilience and mindfulness, and better work environments would experience lower rates of burnout.General surgery residents at 7 sites in the US were invited to complete an electronic survey in 2019 that included the 2-item Maslach Burnout Inventory, Brief Emotional Intelligence Scale, Revised Cognitive and Affective Mindfulness Scale, 2-Item Connor-Davidson Resilience Scale, Utrecht Work Engagement Scale, and Job Resources scale of the Job Demands-Resources Questionnaire. Individual constructs were assessed for association with burnout, using multivariable logistic regression models. Residents' scores were evaluated in aggregate, in groups according to demographic characteristics, and by site.Of 284 residents, 164 completed the survey (response rate 58%). A total of 71% of respondents were at high risk for burnout, with sites ranging from 57% to 85% (p = 0.49). Burnout rates demonstrated no significant difference across gender, PGY level, and respondent age. On bivariate model, no demographic variables were found to be associated with burnout, but the internal characteristics of emotional intelligence, resilience and mindfulness, and the external characteristics of work engagement and job resources were each found to be protective against burnout (p0.001 for all). However, multivariable models examining internal and external characteristics found that no internal characteristics were associated with burnout, while job resources (coeff. -1.0, p-value0.001) and work engagement (coeff. -0.76, p-value 0.032) were significantly protective factors. Rates of engagement overall were high, particularly with respect to work "dedication."A majority of residents at multiple institutions were at high risk for burnout during the study period. Improved work engagement and job resources were found to be more strongly associated with decreased burnout rates when compared to internal characteristics. Although surgical residents appear to already be highly engaged in their work, programs should continue to explore ways to increase job resources, and further research should be aimed at elucidating the mediating effect of internal characteristics on these external factors.

Non-designated preliminary (NDP) general surgery residents face the daunting challenge of obtaining a categorical residency position while undertaking the rigors of a general surgery residency. This additional application cycle represents a stressful time for these trainees and limited data exists to help guide applicants and program directors regarding the factors predictive of application success. While previous studies have focused solely on applicant related factors, no study to date has evaluated the effect of the residency program structure, institutional resources, or administrative support on these outcomes.A multicenter retrospective review of 10 general surgery residency programs over a 5-year period from 2014 to 2019 was performed. Applicant related information was compiled from NDP general surgery residents and the results of their attempted second application into a categorical position. Applicant factors including age, gender, standardized test scores (USMLE/ABSITE), and professional training were examined. Program and administrative structure including residency class size, number of NDP PGY-2 positions, number of assistant program directors and program director (PD) background were also examined. Primary success was defined as a NDP resident successfully obtaining a categorical position within general surgery or a surgical subspecialty. Secondary success was obtaining a categorical residency position in any field of medical practice other than surgery or a surgical subspecialty in the United States.A total of 260 NDP trainees were evaluated with an average age of 29.1. Almost seventy percent of applicants were male, 40% graduated from a non-U.S. medical school and 24.2% required a visa to work in the United States. Thirty 4 percent of NDPs successfully obtained a categorical surgery position and an additional 35% obtained a categorical residency position in a nonsurgical field for an overall match success rate of 68.9%. Factors associated with primary success included ABSITE score (p 0.001), US medical school graduation (p = 0.02), visa status (p = 0.03), presence of preliminary PGY-2 positions (p = 0.02), and PD professional development time (p = 0.004). Overall success was associated USMLE Step 1 scores (p = 0.02), number of approved chiefs (p = 0.03), presence of dedicated faculty researchers (p = 0.001), and PD professional development time (p 0.001).Applicant, program-related, and administrative factors all have a significant impact on the success of NDP general surgery residents in obtaining a categorical surgical position. Trainees should consider all of these factors when applying to NDP residencies and in approaching their second application cycle to maximize their likelihood of a successful match.

The ACS NSQIP Surgical Risk Calculator is designed to estimate the chance of an unfavorable outcome after surgery. Our goal was to evaluate the accuracy of the calculator in our emergency general surgery population. Surgical outcomes were compared to predicted risk. The risk was calculated with surgeon adjustment scores (SASs) of 1 (no adjustment), 2 (risk somewhat higher), and 3 (risk significantly higher than estimate). Two hundred and twenty-seven patients met the inclusion criteria. An SAS of 1 or 2 accurately predicted risk of mortality (5.7% and 8.5% predicted versus 7.9% actual), whereas a risk adjustment of 3 indicated significant overestimation of mortality rate (14.8% predicted). There was good overall prediction performance for most variables with no clear preference for SAS 1, 2, or 3. Poor correlation was seen with SSI, urinary tract infection, and length of stay variables. The ACS NSQIP Surgical Risk Calculator yields valid predictions in the emergency general surgery population, and the data support its use to inform conversations about outcome expectations.

A recent EAST publication emphasized the importance of handoffs to ensure safe and effective care for trauma patients. In this work, we evaluated our existing handoffs from the operating room (OR) to the trauma intensive care unit (TICU) and implemented a formal process at our level 1 trauma center. Pre and post-intervention surveys were offered to the stakeholders. Responses were recorded in a Likert scaled format and results were compared using Student’s t-test with statistical significance was set to .05. 57 surveys were completed (30 pre, 27 post) and 139 handoffs occurred. There was significant improvement in “overall satisfaction” and “understanding of information expected.” Standardizing an OR to intensive care unit handoff clarifies expectations and improves care team satisfaction. While future studies are needed to evaluate the impact of structured handoffs on patient outcomes, provider satisfaction likely serves as an indicator for culture shift towards safer transitions of care for injured patients.

To establish expert consensus regarding the domains and topics for senior surgery residents (PGY-4) to make critical decisions and assume senior-level responsibilities, and to develop the formative American College of Surgeons Senior Resident Readiness Assessment (ACS SRRA) Program.The American College of Surgeons (ACS) education leadership team conducted a focus group with surgical experts to identify the content for an assessment tool to evaluate senior residents' readiness for their increased levels of responsibility. After the focus group, national experts were recruited to develop consensus on the topics through three rounds of surveys using Delphi methodology. The Delphi participants rated topics using Likert-type scales and their comments were incorporated into subsequent rounds. Consensus was defined as ≥ 80% agreement with internal-consistency reliability (Cronbach's alpha) ≥ 0.8. In a stepwise fashion, topics that did not achieve consensus for inclusion were removed from subsequent survey rounds.The surveys were administered via an online questionnaire.Twelve program directors and assistant program directors made up the focus group. The 39 Delphi participants represented seven different surgical subspecialties and were from diverse practice settings. The median length of experience in general surgery resident education was 20 years (IQR 14.3-30.0) with 64% of the experts being either current or past general surgery residency program directors.The response rate was 100% and Cronbach's alpha was ≥ 0.9 for each round. The Delphi participants contributed a large number of comments. Of the 201 topics that were evaluated initially, 120 topics in 25 core clinical areas were included to create the final domains of ACS SRRA.National consensus on the domain of the ACS SRRA has been achieved via the modified Delphi method among expert surgeon educators. ACS SRRA will identify clinical topics and areas in which each senior resident needs improvement and provide data to residents and residency programs to develop individualized learning plans. This would help in preparing the senior residents to assume their responsibilities and support their readiness for future fellowship training or surgical practice.

Integration of advanced practitioners (APs) into academic medical centers can improve processes of care and decrease physician workload but may adversely impact general surgery residency training. The aim of the present study was to characterize general surgery resident perceptions of APs and their impact on resident training. We conducted an institutional review board–approved survey covering five topic areas: knowledge of AP training, interaction with APs, scope-of-practice of APs, role of APs in the health-care team, and impact of APs on physician training. The survey was administered to general surgery residents at six large academic medical centers. One hundred eighteen general surgery residents completed the survey. The majority (43.6%) of respondents were junior residents. All respondents had interactions with APs with 90.7 per cent having worked directly with an AP in the last month. Residents reported minimal formal educational involvement by APs with 6.8 per cent reporting participation in didactics and 22.2 per cent teaching operative techniques. Almost half (44.1%) of the respondents reported that APs played an important role in their education, and 42.4 per cent of respondents disagreed or strongly disagreed that the role of the AP is well defined in their hospital. Today's general surgery residents work closely with APs who seem to positively impact resident education. Although residents perceive significant benefit with integration of APs, well-defined roles are lacking.

Objective Speed mentoring has recently been used by several medical organizations as a strategy to establish mentoring relationships, which are felt to be critically important in the development of the surgeon. This study assesses a surgical speed-mentoring program at the 2015 American College of Surgeons (ACS) Clinical Congress. Design A steering committee designed the speed-mentoring program to match 60 ACS Resident and Associate Society mentees with a mix of junior and senior leadership of ACS. Each mentee met with 5 mentors for 10 minutes each during the 1 hour session. After participation in the activity, surveys were provided to assess the event. The survey included forced-choice questions using Likert-scales as well as open-ended questions. Mentor and mentee responses were compared using Medcalc software using comparison of means and comparison of proportion, with p Setting The study was undertaken at the 2015 ACS Clinical Congress. Participants A total of 60 mentors and 49 mentees participated in the inaugural ACS Speed-Mentoring activity. The postactivity survey was completed by 54 mentors (90%) and 39 mentees (79.5%). Results There was a high level of satisfaction with the activity, with 100% of mentors and mentees stating that they would recommend the activity to a colleague. There was overall high satisfaction with the organization of the session by both the mentors and the mentees although the mentors were more likely to feel that they needed more time for each interaction. More mentees (93%) than mentors (68.5%) felt they were likely to develop a mentoring relationship with one of their matches outside of the organized session. Conclusions We demonstrated that a speed-mentoring event at a national surgical meeting offers an effective platform for mentoring and is mutually beneficial to both mentors and mentees. Data collected here will be used to modify and improve the design of future speed-mentoring sessions.

Surgeon educators express concern about trainees' sense of patient ownership. We aimed to compare resident and faculty perceptions on residents' sense of personal responsibility for patient outcomes and to correlate patient ownership with resident and residency characteristics.An anonymous electronic questionnaire surveyed 373 residents and 390 faculty at seven academic surgery residencies across the United States. We modified an established psychological ownership scale to measure patient ownership among surgical trainees.Respondents included 123 residents and 136 faculty (response rate 33% and 35%, respectively). Overall, 78.0% of faculty agreed that residents took personal responsibility for patient outcomes, but only 26.4% thought residents felt a similar or higher degree of patient ownership compared with themselves. Faculty underestimated the proportion of residents that routinely checked on their patients when off-duty (36.8 versus 92.6%, P 0.001). Higher means on the patient ownership scale correlated with female sex (5.9 versus. 5.5 for males, P = 0.009), advanced post graduate year level (5.3, 5.5, 5.7, 5.8, 6.1, for post graduate year 1-5, respectively, P = 0.02), and the sense that patient outcomes affected the resident respondent's mood (5.8 versus 4.8 for those whose mood was not affected, P 0.001). In addition, trainees who perceived better resident camaraderie (P = 0.004), faculty mentorship (P 0.001), and that their program provided appropriate autonomy (P = 0.03) felt greater responsibility for patient outcomes.Most faculty agree that residents assume personal responsibility for patient outcomes, but many still underestimate residents' sense of patient ownership. Certain modifiable aspects of residency culture including camaraderie, mentorship, and autonomy are associated with patient ownership among trainees.

Blunt thoracic trauma comprises approximately 8% of all traumatic admissions in the United States. While chest wall injuries comprise much of this burden, mediastinal injuries, including cardiac and great vessel injuries, are being recognized more frequently given the diagnostic capabilities of modern CT imaging. In penetrating trauma, close proximity of structures in the mediastinal space, comes with a higher incidence of injury to multiple structures. Further, cardiac injury is estimated to comprise 10% of the mortality of gunshot wound victims, while more than 90% of great vessel injury is associated with penetrating injury, representing a significant burden of disease. Management and care of these injuries requires consideration of multiple details and exposure techniques. This article will address diagnosis, management and repair of esophageal, thoracic duct, cardiac, and great vessel injuries. This review contains 4 figures, 2 tables, and 49 references. Keywords: Mediastinal structures, esophageal injury, esophageal repair, thoracic duct injury, thoracic duct ligation, blunt cardiac injury, penetrating cardiac injury, blunt aortic injury, great vessel injury, endovascular stenting

Background The technique for attaining photographic evidence of the critical view of safety (CVS) in laparoscopic cholecystectomy (LC) has previously been defined; however, the consistency, accuracy, and feasibility of CVS in practice is unknown. The aim of this study was to use an already established image sharing and grading system to determine the feasibility of timely feedback after sharing intraoperative images of the CVS and to evaluate if and how cholecystitis affects the ability to attain a CVS. Study Design We studied 193 laparoscopic cholecystectomies performed by 14 surgeons between August 2017 and January 2019. Anterior and posterior intraoperative CVS images were shared using a standard multimedia messaging system (MMS). Images were graded remotely by members of the group using an established scoring system, and their times to response and scores were recorded. Response data were analyzed for the ability to attain timely and consistent CVS scores. Results There were 74 urgent laparoscopic cholecystectomies for acute cholecystitis and 119 nonurgent cholecystectomies performed during the study period. Scoring of shared images occurred in less than 5 minutes, and peer review (mean 3 responses) showed agreement that was not significantly different. In patients with acute cholecystitis, a small but significant difference was observed between anterior and posterior image scoring agreement. Conclusions An established image sharing and grading system for CVS can be used for real-time intraoperative feedback without increasing operative time or compromising private health information. The CVS is almost always attainable; however, decreases in CVS quality and grading agreement are observed in patients with acute cholecystitis.

Emergency general surgery (EGS) services are designed to increase the availability of timely, high-quality care to patients with urgent surgical problems. One of the most commonly performed operations on such services is cholecystectomy. Improved outcomes have recently been described in early cholecystectomy for cholecystitis. We hypothesized that, as our EGS service matured, time from imaging to operating room (OR) for cholecystectomy would decrease. At an academic referral center, we identified patients undergoing inpatient cholecystectomy for acute cholecystitis during three time periods: before the formation of an EGS service from 2005 to 2007, during the first years of the service from 2008 to 2010, and five years after its development from 2013 to 2014. Charts were reviewed for patient demographics, operative events, and findings. The time of radiologic diagnosis and operation start time were recorded, and time between diagnosis and operation was calculated. A total of 217 patients who met the study criteria were identified, 88 in 2005 to 2007, 84 in 2008 to 2010, and 45 in 2013 to 2014. Time from radiologic diagnosis to OR decreased over the study period, from a median of 48.4 hours in 2005 to 2007 to 32.4 hours in 2008 to 2010 during the early years of the EGS service. Time to OR further decreased to a median of 16.6 hours during 2013 to 2014. The formation and maturation of an EGS service was associated with decreased time to OR after radiologic diagnosis of acute cholecystitis at this institution. This decrease in preoperative time may lead to lower costs and improved outcomes.

Traffic-related injury is a major and increasing cause of global mortality, especially in low- and middle-income countries (LMICs). However, trauma systems, personnel, resources, and infrastructure are frequently insufficient to meet the needs of the population in this at-risk population in LMICs. In addition, these resources are not uniformly distributed, coordinated, nor well described within most countries. Trauma care resources have not previously been characterized in the Northern Region of Ghana. We performed uniform site evaluations and interviews at 92 hospitals in Northern Ghana. Trauma systems, material resources, and human resources were quantified. Equipment was characterized as available in the Emergency Department (ED), in the hospital only, or unavailable. Hospitals were categorized as primary, district, or referral. Forty-two primary hospitals, 48 district hospitals, 3 regional hospitals, and 1 teaching hospital were surveyed. Over 95 % of hospitals reported having no training or systems for the care of injured patients. Substantial clinical equipment deficits were found at most primary hospitals. In over 90 % of these hospitals, the majority of circulation and monitoring, airway and breathing, and diagnostic imagining resources were not available. Equipment was also frequently unavailable at district and regional hospitals. When available, these resources were infrequently present in the ED. Although resources may be unavoidably constrained, there are substantial opportunities to improve the systematic management of trauma care and improve the education of the medical providers regarding care of injured patients in the region studied.

Importance The human patient simulators that are currently used in multidisciplinary operating room team training scenarios cannot simulate surgical tasks because they lack a realistic surgical anatomy. Thus, they eliminate the surgeon’s primary task in the operating room. The surgical trainee is presented with a significant barrier when he or she attempts to suspend disbelief and engage in the scenario. Objective To develop and test a simulation-based operating room team training strategy that challenges the communication abilities and teamwork competencies of surgeons while they are engaged in realistic operative maneuvers. Design, Setting, and Participants This pre-post educational intervention pilot study compared the gains in teamwork skills for midlevel surgical residents at Wake Forest Baptist Medical Center after they participated in a standardized multidisciplinary team training scenario with 3 possible levels of surgical realism: (1) SimMan (Laerdal) (control group, no surgical anatomy); (2) “synthetic anatomy for surgical tasks” mannequin (medium-fidelity anatomy), and (3) a patient simulated by a deceased donor (high-fidelity anatomy). Interventions Participation in the simulation scenario and the subsequent debriefing. Main Outcomes and Measures Teamwork competency was assessed using several instruments with extensive validity evidence, including the Nontechnical Skills assessment, the Trauma Management Skills scoring system, the Crisis Resource Management checklist, and a self-efficacy survey instrument. Participant satisfaction was assessed with a Likert-scale questionnaire. Results Scenario participants included midlevel surgical residents, anesthesia providers, scrub nurses, and circulating nurses. Statistical models showed that surgical residents exposed to medium-fidelity simulation (synthetic anatomy for surgical tasks) team training scenarios demonstrated greater gains in teamwork skills compared with control groups (SimMan) (Nontechnical Skills video score: 95% CI, 1.06-16.41; Trauma Management Skills video score: 95% CI, 0.61-2.90) and equivalent gains in teamwork skills compared with high-fidelity simulations (deceased donor) (Nontechnical Skills video score: 95% CI, −8.51 to 6.71; Trauma Management Skills video score: 95% CI, −1.70 to 0.49). Conclusions and Relevance Including a surgical task in operating room team training significantly enhanced the acquisition of teamwork skills among midlevel surgical residents. Incorporating relatively inexpensive, medium-fidelity synthetic anatomy in human patient simulators was as effective as using high-fidelity anatomies from deceased donors for promoting teamwork skills in this learning group.

Pancreatic or peripancreatic tissue necrosis confers substantial morbidity and mortality. New modalities have created a wide variation in approaches and timing of interventions for necrotizing pancreatitis. As acute care surgery evolves, its practitioners are increasingly being called upon to manage these complex patients.A systematic review of the MEDLINE database using PubMed was performed. English language articles regarding pancreatic necrosis from 1980 to 2014 were included. Letters to the editor, case reports, book chapters, and review articles were excluded. Topics of investigation included operative timing, the use of adjuvant therapy and the type of operative repair. Grading of Recommendations, Assessment, Development and Evaluations methodology was applied to question development, outcome prioritization, evidence quality assessments, and recommendation creation.Eighty-eight studies were included and underwent full review. Increasing the time to surgical intervention had an improved outcome in each of the periods evaluated (72 hours, 12-14 days, 30 days) with a significant improvement in outcomes if surgery was delayed 30 days. The use of percutaneous and endoscopic procedures was shown to postpone surgery and potentially be definitive. The use of minimally invasive surgery for debridement and drainage has been shown to be safe and associated with reduced morbidity and mortality.Acute Care Surgeons are uniquely trained to care for those with pancreatic necrosis due their training in critical care and complex surgery with ongoing shock. In adult patients with pancreatic necrosis, we recommend that pancreatic necrosectomy be delayed until at least day 12. During the first 30 days of symptoms with infected necrotic collections, we conditionally recommend surgical debridement only if the patients fail to improve after radiologic or endoscopic drainage. Finally, even with documented infected necrosis, we recommend that patients undergo a step-up approach to surgical intervention as the preferred surgical approach.Systematic review/guideline, level III.

Emergency general surgery (EGS) services are designed to increase the availability of timely, high-quality care to patients with urgent surgical problems. One of the most commonly performed operations on such services is cholecystectomy. Improved outcomes have recently been described in early cholecystectomy for cholecystitis. We hypothesized that, as our EGS service matured, time from imaging to operating room (OR) for cholecystectomy would decrease. At an academic referral center, we identified patients undergoing inpatient cholecystectomy for acute cholecystitis during three time periods: before the formation of an EGS service from 2005 to 2007, during the first years of the service from 2008 to 2010, and five years after its development from 2013 to 2014. Charts were reviewed for patient demographics, operative events, and findings. The time of radiologic diagnosis and operation start time were recorded, and time between diagnosis and operation was calculated. A total of 217 patients who met the study criteria were identified, 88 in 2005 to 2007, 84 in 2008 to 2010, and 45 in 2013 to 2014. Time from radiologic diagnosis to OR decreased over the study period, from a median of 48.4 hours in 2005 to 2007 to 32.4 hours in 2008 to 2010 during the early years of the EGS service. Time to OR further decreased to a median of 16.6 hours during 2013 to 2014. The formation and maturation of an EGS service was associated with decreased time to OR after radiologic diagnosis of acute cholecystitis at this institution. This decrease in preoperative time may lead to lower costs and improved outcomes.

Many states do not require a license to operate a moped, defined as a motor vehicle with less than 50-cc engine displacement. These vehicles may therefore serve as a mode of transportation for those who are driving without a license and who may have a history of prior high-risk behavior. We hypothesized that those involved in moped collisions were more likely to have previous convictions for driving while intoxicated (DWI) and other non-DWI offenses than those on conventional motorcycles. At a Level I trauma center, we queried the trauma registry from January 2005 to October 2010 for admissions after motorcycle or moped collisions. Classification of mechanism of injury was verified through chart review. Corrections databases from our state were then reviewed for previous convictions for DWI and other offenses. One thousand seventy-three patients over the study period were involved in motorcycle or moped collisions; 94 were from another state. Of the patients identified from our state, 249 had moped collisions and 730 had motorcycle collisions. Forty-nine per cent (121) of moped drivers had a history of DWI versus only 8 per cent (56) of motorcycle drivers ( P ≤ 0.05). Sixty-four per cent (161) of moped drivers were previously convicted of a crime versus 20 per cent (146) of those on motorcycles ( P ≤ 0.05). Moped drivers were significantly more likely to have a prior conviction of DWI as well as prior convictions of other crimes, establishing a pattern of disregard for the law. The use of these vehicles without a license likely presents a risk to public safety. Legislation to require licensing before moped operation should be considered.

Background Nonoperative management (NOM) of blunt splenic injury is well accepted. Substantial failure rates in higher injury grades remain common, with one large study reporting rates of 19.6%, 33.3%, and 75% for grades III, IV, and V, respectively. Retrospective data show angiography and embolization can increase salvage rates in these severe injuries. We developed a protocol requiring referral of all blunt splenic injuries, grades III to V, without indication for immediate operation for angiography and embolization. We hypothesized that angiography and embolization of high-grade blunt splenic injury would reduce NOM failure rates in this population. Study Design This was a prospective study at our Level I trauma center as part of a performance-improvement project. Demographics, injury characteristics, and outcomes were compared with historic controls. The protocol required all stable patients with grade III to V splenic injuries be referred for angiography and embolization. In historic controls, referral was based on surgeon preference. Results From January 1, 2010 to December 31, 2012, there were 168 patients with grades III to V spleen injuries admitted; NOM was undertaken in 113 (67%) patients. The protocol was followed in 97 patients, with a failure rate of 5%. Failure rate in the 16 protocol deviations was 25% (p = 0.02). Historic controls from January 1, 2007 to December 31, 2009 were compared with the protocol group. One hundred and fifty-three patients with grade III to V injuries were admitted during this period, 80 (52%) patients underwent attempted NOM. Failure rate was significantly higher than for the protocol group (15%, p = 0.04). Conclusions Use of a protocol requiring angiography and embolization for all high-grade spleen injuries slated for NOM leads to a significantly decreased failure rate. We recommend angiography and embolization as an adjunct to NOM for all grade III to V splenic injuries.

Aging worsens outcome in traumatic brain injury (TBI), but available studies may not provide accurate outcomes predictions due to confounding associated injuries. Our goal was to develop a predictive tool using variables available at admission to predict outcomes related to severity of brain injury in aging patients.Characteristics and outcomes of blunt trauma patients, aged 50 or older, with isolated TBI, in the National Trauma Data Bank (NTDB), were evaluated. Equations predicting survival and independence at discharge (IDC) were developed and validated using patients from our trauma registry, comparing predicted with actual outcomes.Logistic regression for survival and IDC was performed in 57,588 patients using age, sex, Glasgow Coma Scale score (GCS), and Revised Trauma Score (RTS). All variables were independent predictors of outcome. Two models were developed using these data. The first included age, sex, and GCS. The second substituted RTS for GCS. C statistics from the models for survival and IDC were 0.90 and 0.82 in the GCS model. In the RTS model, C statistics were 0.80 and 0.67. The use of GCS provided better discrimination and was chosen for further examination. Using a predictive equation derived from the logistic regression model, outcome probabilities were calculated for 894 similar patients from our trauma registry (January 2012 to March 2016). The survival and IDC models both showed excellent discrimination (p0.0001). Survival and IDC generally decreased by decade: age 50 to 59 (80% IDC, 6.5% mortality), 60 to 69 (82% IDC, 7.0% mortality), 70 to 79 (76% IDC, 8.9% mortality), and 80 to 89 (67% IDC, 13.4% mortality).These models can assist in predicting the probability of survival and IDC for aging patients with TBI. This provides important data for loved ones of these patients when addressing goals of care.

BACKGROUND Emergency physicians (EPs) often care for patients with acute small bowel obstruction. While some patients require exploratory laparotomy, others are managed successfully with supportive care. We aimed to determine features that predict the need for operative management in emergency department (ED) patients with small bowel obstruction (SBO). METHODS We performed a retrospective chart review of 370 consecutive patients admitted to a large urban academic teaching hospital with a diagnosis of SBO over a two-year period. We evaluated demographic characters (prior SBO, prior abdominal surgery, active malignancy) and clinical findings (leukocytosis and lactic acid) to determine features associated with the need for urgent operative intervention. RESULTS Patients with a prior SBO were less likely to undergo operative intervention [20.3% (42/207)] compared to those without a prior SBO [35.2% (57/162)]. Abnormal bloodwork was not associated with need for operative intervention. 68% of patients with CT scan findings of both an SBO and a hernia, however, were operatively managed. CONCLUSIONS Patients with a history of SBO were less likely to require operative intervention at any point during their hospitalization. Abnormal bloodwork was not associated with operative intervention. The CT finding of a hernia, however, predicted the need for operative intervention, while other findings (ascites, duodenal thickening) did not. Further research would be helpful to construct a prediction rule, which could help community EPs determine which patients may benefit from expedited transfer for operative management, and which patients could be safely managed conservatively as an initial treatment strategy.

BACKGROUND: : The early resuscitation occurs in the emergency department (ED) where intensive care unit protocols do not always extend and monitoring capabilities vary. Our hypothesis is that increased ED length of stay (LOS) leads to increased hospital mortality in patients not undergoing immediate surgical intervention. METHODS: : We examined all trauma activation admissions from January 2002 to July 2009 admitted to the Trauma Service (n = 3,973). Exclusion criteria were as follows: patients taken to the operating room within the first 2 hours of ED arrival, nonsurvivable brain injury, and ED deaths. Patients spending >5 hours in the ED were not included in the analysis because of significantly lower acuity and mortality. RESULTS: : Patients spent a mean of 3.2 hours ± 1 hour in the ED during their initial evaluation. Hospital mortality increases for each additional hour a patient spends in the ED, with 8.3% of the patients staying in the ED between 4 hours and 5 hours ultimately dying (p = 0.028). ED LOS measured in minutes is an independent predictor of mortality (odds ratio, 1.003; 95% confidence interval, 1.010-1.006; p = 0.014) when accounting for Injury Severity Score, Revised Trauma Score, and age. Linear regression showed that a longer ED LOS was associated with anatomic injury pattern rather than physiologic derangement. CONCLUSION: : In this patient population, a longer ED LOS is associated with an increased hospital mortality even when controlling for physiologic, demographic, and anatomic factors. This highlights the importance of rapid progression of patients through the initial evaluation process to facilitate placement in a location that allows implementation of early goal directed trauma resuscitation.

Importance Prior studies demonstrate a high prevalence of burnout and depression among surgeons. Limited data exist regarding how these conditions are perceived by the surgical community. Objectives To measure prevalence of burnout and depression among general surgery trainees and to characterize how residents and attendings perceive these conditions. Design, Setting, and Participants This cross-sectional study used unique, anonymous surveys for residents and attendings that were administered via a web-based platform from November 1, 2016, through March 31, 2017. All residents and attendings in the 6 general surgery training programs in North Carolina were invited to participate. Main Outcomes and Measures The prevalence of burnout and depression among residents was assessed using validated tools. Burnout was defined by high emotional exhaustion or depersonalization on the Maslach Burnout Inventory. Depression was defined by a score of 10 or greater on the Patient Health Questionnaire–9. Linear and logistic regression models were used to assess predictive factors for burnout and depression. Residents’ and attendings’ perceptions of these conditions were analyzed for significant similarities and differences. Results In this study, a total of 92 residents and 55 attendings responded. Fifty-eight of 77 residents with complete responses (75%) met criteria for burnout, and 30 of 76 (39%) met criteria for depression. Of those with burnout, 28 of 58 (48%) were at elevated risk of depression ( P = .03). Nine of 77 residents (12%) had suicidal ideation in the past 2 weeks. Most residents (40 of 76 [53%]) correctly estimated that more than 50% of residents had burnout, whereas only 13 of 56 attendings (23%) correctly estimated this prevalence ( P P = .002). Sixty-six of 73 residents (90%) and 40 of 51 attendings (78%) identified the same top 3 barriers to seeking care for burnout: inability to take time off to seek treatment, avoidance or denial of the problem, and negative stigma toward those seeking care. Conclusions and Relevance The prevalence of burnout and depression was high among general surgery residents in this study. Attendings and residents underestimated the prevalence of these conditions but acknowledged common barriers to seeking care. Discrepancies in actual and perceived levels of burnout and depression may hinder wellness interventions. Increasing understanding of these perceptions offers an opportunity to develop practical solutions.

Background: The administration of etomidate for rapid sequence induction (RSI) has been linked to subsequent adrenocortical insufficiency in nontrauma patients. However, etomidate-related adrenocortical insufficiency has not been well studied in the trauma population. Purpose: We performed a prospective, randomized, controlled study to assess the effect of one dose of etomidate for RSI on adrenal function and its clinical significance during and after resuscitation in trauma patients. Methods: Adult trauma patients admitted to our Level I trauma center requiring RSI were randomized to receive etomidate 0.3 mg/kg and succinylcholine 1 mg/kg (E group) or fentanyl 100 μg, midazolam 5 mg, and succinylcholine 1 mg/kg (FM group) for induction. A baseline serum cortisol level was drawn before RSI. Four to six hours after RSI, a postintubation serum cortisol level was drawn. An ACTH stimulation test was performed. Results: Thirty patients were enrolled: 18 E group patients and 12 FM group patients. No statistical difference was detected between the two groups with respect to age, injury severity score, and baseline serum cortisol. Mean serum cortisol levels were significantly lower in E group patients than in FM group patients 4 to 6 hours after intubation (18.2 vs. 27.8 μg/dL, p < 0.05). Change in serum cortisol between baseline and postintubation levels was different (-12.8 μg/dL ± 9.6 /μg/dL vs. 1.1 μg/dL ± 7.6 μg/dL, p < 0.01). Patients in the E group had an average increase in cortisol after ACTH administration of 4.2 /μg/dL ± 4.9 μg/dL vs. 11.2 μg/dL ± 6.1 μg/dL in the FM group, p < 0.001. Patients in the E group required longer ICU lengths of stay (mean, 6.3 days vs. 1.5 days, p < 0.05), more ventilator days (mean, 28 days vs. 17 days, p < 0.01), and longer hospital lengths of stay (mean, 11.6 days vs. 6.4 days, p < 0.01). Conclusions: The use of etomidate for RSI in trauma patients led to chemical evidence of adrenocortical insufficiency and may have contributed to increased hospital and ICU lengths of stay and increased ventilator days. Further studies should be considered to evaluate the safety profile of this drug in trauma patients.

Many states do not require a license to operate a moped, defined as a motor vehicle with less than 50-cc engine displacement. These vehicles may therefore serve as a mode of transportation for those who are driving without a license and who may have a history of prior high-risk behavior. We hypothesized that those involved in moped collisions were more likely to have previous convictions for driving while intoxicated (DWI) and other non-DWI offenses than those on conventional motorcycles. At a Level I trauma center, we queried the trauma registry from January 2005 to October 2010 for admissions after motorcycle or moped collisions. Classification of mechanism of injury was verified through chart review. Corrections databases from our state were then reviewed for previous convictions for DWI and other offenses. One thousand seventy-three patients over the study period were involved in motorcycle or moped collisions; 94 were from another state. Of the patients identified from our state, 249 had moped collisions and 730 had motorcycle collisions. Forty-nine per cent (121) of moped drivers had a history of DWI versus only 8 per cent (56) of motorcycle drivers (P ≤ 0.05). Sixty-four per cent (161) of moped drivers were previously convicted of a crime versus 20 per cent (146) of those on motorcycles (P ≤ 0.05). Moped drivers were significantly more likely to have a prior conviction of DWI as well as prior convictions of other crimes, establishing a pattern of disregard for the law. The use of these vehicles without a license likely presents a risk to public safety. Legislation to require licensing before moped operation should be considered.

In some populations, intensive care unit (ICU) mobility has been shown to be safe and beneficial. We gathered data on 50 nonintubated surgical patients in a 10-bed surgical ICU (SICU) who met physiologic inclusion criteria beginning in May 2008 (A group). In January 2009, we began mandatory entry of computerized mobility orders as part of a standardized ICU order set. We also created a mobility protocol for nurses in this ICU. We then collected data on 50 patients in this postintervention cohort (B group). Both groups had similar baseline characteristics. A group patients had some form of mobility orders entered in 29 patients (58%) versus 47 patients (82%) in the B group, P0.05. In the A group, 11 patients (22%) were mobilized; in the B group, 40 patients (80%) were mobilized, P0.05. In our SICU patient population, mandatory entry of computerized mobility orders as part of a standard SICU order set and establishment of an ICU mobility nursing protocol was associated with an increase in number of mobility orders entered as well as an increase in SICU patient activity. Further studies should focus on measurement of the effect of mobility interventions on patient outcomes.
