ABSTRACT
Acute care surgery (ACS) encompasses five major pillars - trauma, surgical critical care, emergency general surgery, elective general surgery and surgical rescue. The specialty continues to evolve and due to high-acuity, high-volume and around-the-clock care, the workload can be significant leading to workforce challenges such as rightsizing of staff, work-life imbalance, surgeon burnout and more. To address these challenges and ensure a stable workforce, ACS as a specialty must be deliberate and thoughtful about how it manages workload and workforce going forward. In this article, we address the importance, benefits and challenges of defining full-time equivalence for ACS as a method to establish a stable ACS workforce for the future.
ABSTRACT
BACKGROUND: Patients with gallstone pancreatitis (GP) or choledocholithiasis (CDL) may have common bile duct (CBD) stones that persist until cholangiography. The aim of this study is to evaluate pre-cholangiogram factors that predict persistent CBD stones. METHODS: Multiple logistic regression analyses were performed to identify demographic, laboratory, and radiologic predictors of persistent CBD stones and non-therapeutic cholangiography among adults with GP or CDL. RESULTS: In 152 patients from 2010 to 2015, preoperative diagnosis, presence of a CBD stone on US, and age ≥ 60 years were associated with persistent CBD stones. Two risk factors alone had a PPV of 88% and the absence of all risk factors had a NPV of 94%. Age < 60 years and the absence of a CBD stone on US were most predictive of non-therapeutic cholangiography. CONCLUSION: Age, LFTs, and US help predict persistent CBD stones in patients initially presenting with GP or CDL and help minimize non-therapeutic preoperative cholangiography.

BACKGROUND: Failure to provide adequate nutrition in the intensive care unit (ICU) may be particularly harmful for patients with prolonged critical illness. We hypothesized that early nutrition inadequacy is more influential for those requiring a longer ICU stay versus those requiring a shorter stay. METHODS: We enrolled 280 adult patients with prolonged surgical ICU stay who were receiving enteral nutrition for >72 hours. Subjects were divided into 2 groups: shortICU (<14 days) and longICU (≥14 days). Nutrition deficits at ICU days 3 and 7 were calculated. To investigate whether early nutrient deficit was associated with ICU length of stay (LOS), hospital LOS, 28-day ventilator-free days, and discharge disposition (home/rehabilitation vs death/nursing home), we performed linear and logistic regression analyses controlling for age, sex, body mass index, and APACHE II (Acute Physiology and Chronic Health Evaluation). RESULTS: While the shortICU (n = 163) and longICU (n = 117) groups were similar in age, APACHE II, Injury Severity Score, energy/protein prescription, and enteral nutrition initiation within 48 hours, the longICU group was more commonly male (76% vs 61%, P = .007) and had higher body mass index (27.4 vs 25.6, P = .007). Significant interactions occurred: in the longICU group but not the shortICU group, protein deficits were associated with longer ICU stay and fewer 28-day ventilator-free days. CONCLUSIONS: Early protein deficits accumulating at ICU days 3 and 7 are associated with worse clinical outcomes among patients requiring longer ICU stays. Additional studies are required to confirm these findings.

PURPOSE: To explore whether psoas cross sectional area (CSA) and density (Hounsfield Units, HU) are associated with nutritional adequacy and clinical outcomes in surgical intensive care unit patients. MATERIALS AND METHODS: Subjects with at least one CT scan within 72h of ICU admission were included. Demographic, nutritional, radiographic, and outcomes data were collected. Psoas muscle CSA and HU were assessed at the L4-L5 intervertebral disk level. Change (Δ) in CSA and HU overall and per day were calculated. RESULTS: 140 patients were included. There was no significant correlation between baseline CSA and HU and clinical outcomes. Patients with at least two CT scans (n=65), had a median decrease in CSA of -15% [IQR: -20%, -8%] and decrease in HU of -2% [IQR: -30%, +24%]. Patients with the greatest daily %HU decline received significantly fewer calories/kg and proteins/kg and accumulated greater protein deficits at day 7 and overall. Patients with daily %HU increase had the shortest ICU and hospital LOS and more ventilator-free days in univariate and multivariable analyses. CONCLUSIONS: In this exploratory study, early nutritional deficits were correlated with muscle quality deterioration. Inpatient gain in psoas density, compared to maintenance or loss, is associated with shorter hospital stay.

BACKGROUND: Modern trauma systems differ worldwide, possibly leading to disparities in outcomes. We aim to compare characteristics and outcomes of blunt polytrauma patients admitted to two Level 1 Trauma Centers in the US (USTC) and the Netherlands (NTC). METHODS: For this retrospective study the records of 1367 adult blunt trauma patients with an Injury Severity Score (ISS) ≥ 16 admitted between July 1, 2011 and December 31, 2013 (640 from NTC, 727 from USTC) were analysed. RESULTS: The USTC group had a higher Charlson Comorbidity Index (mean [standard deviation] 1.15 [2.2] vs. 1.73 [2.8], p<0.0001) and Injury Severity Score (median [interquartile range, IQR] 25 [17-29] vs. 21 [17-26], p<0.0001). The in-hospital mortality was similar in both centers (11% in USTC vs. 10% NTC), also after correction for baseline differences in patient population in a multivariable analysis (adjusted odds ratio 0.95, 95% confidence interval 0.61-1.48, p=0.83). USTC patients had a longer Intensive Care Unit stay (median [IQR] 4 [2-11] vs. 2 [2-7] days, p=0.006) but had a shorter hospital stay (median [IQR] 6 [3-13] vs. 8 [4-16] days, p<0.0001). USTC patients were discharged more often to a rehabilitation center (47% vs 10%) and less often to home (46% vs. 66%, p<0.0001), and had a higher readmission rate (8% vs. 4%, p=0.01). CONCLUSION: Although several outcome parameters differ in two urban area trauma centers in the USA and the Netherlands, the quality of care for trauma patients, measured as survival, is equal. Other outcomes varied between both trauma centers, suggesting that differences in local policies and processes do influence the care system, but not so much the quality of care as reflected by survival.

BACKGROUND: The neutrophil/lymphocyte ratio (NLR) has been associated as a predictor for increased mortality in critically ill patients. We sought to determine the relationship between NLR and outcomes in adult trauma patients with severe hemorrhage requiring the initiation of massive transfusion protocol (MTP). We hypothesized that the NLR would be a prognostic indicator of mortality in this population. METHODS: This was a multi-institutional retrospective cohort study of adult trauma patients (≥18 years) with severe hemorrhage who received MTP between November 2014 and November 2015. Differentiated blood cell counts obtained at days 3 and 10 were used to obtain NLR. Receiver operating characteristic (ROC) curve analysis assessed the predictive capacity of NLR on mortality. To identify the effect of NLR on survival, Kaplan-Meier (KM) survival analysis and Cox regression models were used. RESULTS: A total of 285 patients with severe hemorrhage managed with MTP were analyzed from six participating institutions. Most (80%) were men, 57.2% suffered blunt trauma. Median (IQR) age, Injury Severity Score, and Glasgow Coma Scale were 35 (25-47), 25 (16-36), and 9 (3-15), respectively. Using ROC curve analysis, optimal NLR cutoff values of 8.81 at day 3 and 13.68 at day 10 were calculated by maximizing the Youden index. KM curves at day 3 (p = 0.05) and day 10 (p = 0.02) revealed an NLR greater than or equal to these cutoff values as a marker for increased in-hospital mortality. Cox regression models failed to demonstrate an NLR over 8.81 as predictive of in-hospital mortality at day 3 (p = 0.056) but was predictive for mortality if NLR was greater than 13.68 at day 10 (p = 0.036). CONCLUSIONS: NLR is strongly associated with early mortality in patients with severe hemorrhage managed with MTP. Further research is needed to focus on factors that can ameliorate NLR in this patient population. LEVEL OF EVIDENCE: Prognostic study, level III.

BACKGROUND: New onset atrial fibrillation (AF) in critically ill surgical patients is associated with significant morbidity and increased mortality. N-terminal pro-B type natriuretic peptide (NT-proBNP) is released by cardiomyocytes in response to stress and may predict AF development after surgery. We hypothesized that elevated NT-proBNP level at surgical intensive care unit (ICU) admission predicts AF development in a general surgical and trauma population. METHODS: From July to October 2015, NT-proBNP concentrations were measured at ICU admission. Abnormal NT-proBNP concentrations were defined by age-adjusted cut-offs. We examined the relationship between the development of AF and demographics, clinical variables, and NT-proBNP level using univariate analysis and a multivariable logistic regression model. RESULTS: Three hundred eighty-seven subjects were included in the cohort, none of whom were in AF at ICU admission. The median age was 63 years (52-73 years), and 40.3% were women. The risk of developing AF was higher for abnormal versus normal NT-proBNP (22% vs. 4%; p < 0.0001). Using optimal derived cutoffs (regardless of age), the risk of developing AF was 2% for NT-proBNP less than 600 ng/L, 15% for NT-proBNP of 600 ng/L to 1,999 ng/L, and 27% for NT-proBNP of 2,000 ng/L or greater. Multiple logistic regression analysis identified three independent predictors for new-onset AF: age, older than 70 years (odds ratio [OR], 3.7, 95% confidence interval [CI], 1.5-9.3), history of AF (OR, 25.3; 95% CI, 9.6-67.0), and NT-proBNP of 600 or greater (OR, 4.3; 95% CI, 1.3-14.2). When none or only one predictor was present, AF incidence was less than 1%. When all three predictors were present, AF incidence was 66%. For subjects 70 years or older but no history of AF, AF incidence was 12.8% when NT-proBNP was 600 or greater compared with 0% when NT-proBNP was less than 600. For subjects younger than 70 years with a history of AF, AF incidence was 44.4% when NT-proBNP was 600 or higher compared to 0% when NT-proBNP was less than 600. CONCLUSION: Elevated NT-proBNP at ICU admission in general surgical and trauma patients is predictive of AF development in the first 3 ICU days. Addition of NT-proBNP measurement to known risk factors can improve predictive power and identify patients who might potentially benefit from evidence-based prophylactic treatment for AF.

BACKGROUND: An intraoperative adverse event (iAE) is often directly attributable to the surgeon's technical error and/or suboptimal intraoperative judgment. We aimed to examine the psychological impact of iAEs on surgeons as well as the surgeons' attitude about iAE reporting. STUDY DESIGN: We conducted a web-based cross-sectional survey of all surgeons at 3 major teaching hospitals of the same university. The 29-item questionnaire was developed using a systematic closed and open approach focused on assessing the surgeons' personal account of iAE incidence, emotional response to iAEs, available support systems, and perspective about the barriers to iAE reporting. RESULTS: The response rate was 44.8% (n = 126). Mean age of respondents was 49 years, 77% were male, and 83% performed >150 procedures/year. During the last year, 32% recalled 1 iAE, 39% recalled 2 to 5 iAEs, and 9% recalled >6 iAEs. The emotional toll of iAEs was significant, with 84% of respondents reporting a combination of anxiety (66%), guilt (60%), sadness (52%), shame/embarrassment (42%), and anger (29%). Colleagues constituted the most helpful support system (42%) rather than friends or family; a few surgeons needed psychological therapy/counseling. As for reporting, 26% preferred not to see their individual iAE rates, and 38% wanted it reported in comparison with their aggregate colleagues' rate. The most common barriers to reporting iAEs were fear of litigation (50%), lack of a standardized reporting system (49%), and absence of a clear iAE definition (48%). CONCLUSIONS: Intraoperative AEs occur often, have a significant negative impact on surgeons' well-being, and barriers to transparency are fear of litigation and absence of a well-defined reporting system. Efforts should be made to support surgeons and standardize reporting when iAEs occur.

INTRODUCTION: Hypophosphatemia has been associated with refeeding malnourished patients, but its clinical significance is unclear. We investigated the incidence of refeeding hypophosphatemia (RH) in the surgical intensive care unit (SICU) and its association with early enteral nutrition (EN) administration and clinical outcomes. METHODS: We performed a retrospective review of a 2-year database of patients receiving EN in the SICU. RH was defined as a post-EN phosphorus (PHOS) level decrement of >0.5 mg/dL to a nadir <2.0 mg/dL within 8 days from EN initiation. We investigated the risk factors for RH and examined its association with clinical outcomes using multivariable regression analyses. RESULTS: In total, 213 patients comprised our analytic cohort. Eighty-three of 213 (39%) individuals experienced RH and 43 of 130 (33%) of the remaining patients experienced non-RH hypophosphatemia (nadir PHOS level <2.0 mg/dL). Overall, there was a total 59% incidence of hypophosphatemia of any cause (N = 126). Nutrition parameters did not differ between groups; most patients were initiated on EN within 48 hours of SICU admission, and timing of EN initiation was not a significant predictor for the development of RH. The median hospital length of stay (LOS) was 21 and 24 days for those with and without RH, respectively ( P = .79); RH remained a nonsignificant predictor for hospital LOS in the multivariable analysis. CONCLUSIONS: RH is common in the SICU but is not related to timing or amount of EN. Hypophosphatemia is also common in the critically ill, but regardless of etiology, it was not found to be a predictor of worse clinical outcomes.

PURPOSE: The goal of this study was to investigate barriers to timely antibiotic administration in septic surgical intensive care unit (SICU) patients and examine the impact of a multidisciplinary bundle on the time from prescription to antibiotic administration. METHODS: This was a pre- and postintervention study that consisted of 3 phases: (1) preintervention phase, retrospective evaluation of data, (2) intervention implementation, and (3) a postintervention phase. A nurse survey was conducted to identify barriers to rapid antibiotic administration during phase 1. Based on this survey, multidisciplinary interventions included adding antibiotics to the automatic dispensing cabinet, educating monthly staff, and providing an antibiotic dosing table to all prescribers, which is attached to the computer workstations. Our multidisciplinary team consisted of the ICU medical directors, nurse managers, nurses, a critical care fellow, and ICU pharmacists. RESULTS: The percentage of antibiotics that were received within 60 minutes was 26.3% in the pregroup versus 84.0% in the postgroup ( P < .001). The mean total prescriber to patient time was 110 minutes in the pregroup versus 58.4 minutes in the postgroup ( P < .001). CONCLUSION: We achieved a higher rate of timely antibiotic administration among septic SICU patients by implementing process changes based on barriers identified by the nurses.

BACKGROUND: Based on the current literature, it is unclear whether advanced age itself leads to higher mortality in critically ill patients or whether it is due to the greater number of comorbidities in the elderly patients. We hypothesized that increasing age would increase the odds of short-term and long-term mortality after adjusting for baseline comorbidities in intensive care unit (ICU) patients. METHODS: We performed a retrospective cohort study of 57 160 adults admitted to any ICU over 5 years at 2 academic tertiary care centers. Patients were divided into age-groups, 18 to 39, 40 to 59, 60 to 79, and ≥80. The primary outcomes were 30-day and 365-day mortality. Results were analyzed with multivariate logistic regression adjusting for demographics and the Elixhauser-van Walraven Comorbidity Index. RESULTS: The adjusted 30-day mortality odds ratios (ORs) were 1.39 (95% confidence interval [CI]: 1.21-1.60), 2.00 (95% CI: 1.75-2.28), and 3.33 (95% CI: 2.90-3.82) for age-groups 40 to 59, 60 to 79, and ≥80, respectively, using the age-group 18 to 39 as the reference. The adjusted 365-day mortality ORs were 1.46 (95% CI: 1.32-1.61), 2.10 (95% CI: 1.91-2.31), and 2.96 (95% CI: 2.67-3.27). CONCLUSION: In critically ill patients, increasing age is associated with higher odds of short-term and long-term death after correcting for existing comorbidities.

This is a recommended management algorithm from the Western Trauma Association addressing the management of adult patients with rib fractures. Because there is a paucity of published prospective randomized clinical trials that have generated Class I data, these recommendations are based primarily on published observational studies and expert opinion of Western Trauma Association members. The algorithm and accompanying comments represent a safe and sensible approach that can be followed at most trauma centers. We recognize that there will be patient, personnel, institutional, and situational factors that may warrant or require deviation from the recommended algorithm. We encourage institutions to use this as a guideline to develop their own local protocols.

BACKGROUND: As it addresses both technical and nontechnical skills, simulation-based training is playing an increasingly important role in surgery. In addition to the focus on skill acquisition, it is also important to ensure that surgeons are able to perform a variety of tasks in unique and challenging situations. These situations include responding to mass casualties, dealing with disease outbreaks, and preparing for wartime missions. Simulation-based training can be a valuable training modality in these situations, as it allows opportunities to practice and prepare for high-risk and often low-frequency events. METHODS: During the 8th Annual Meeting of the Consortium of the American College of Surgeons-Accredited Education Institutes in March 2015, a multidisciplinary panel was assembled to discuss how simulation can be used to prepare the surgical community for such high-risk events. CONCLUSION: An overview of how simulation has been used to address needs in each of these situations is presented.

This paper presents a simulation of Virtual Airway Skill Trainer (VAST) tasks. The simulated tasks are a part of two main airway management techniques; Endotracheal Intubation (ETI) and Cricothyroidotomy (CCT). ETI is a simple nonsurgical airway management technique, while CCT is the extreme surgical alternative to secure the airway of a patient. We developed identification of Mallampati class, finding the optimal angle for positioning pharyngeal/mouth axes tasks for ETI and identification of anatomical landmarks and incision tasks for CCT. Both ETI and CCT simulators were used to get physicians' feedback at Society for Education in Anesthesiology and Association for Surgical Education spring meetings. In this preliminary validation study, total 38 participants for ETI and 48 for CCT performed each simulation task and completed pre and post questionnaires. In this work, we present the details of the simulation for the tasks and also the analysis of the collected data from the validation study.

BACKGROUND: There currently exists no preoperative risk stratification system for emergency surgery (ES). We sought to develop an Emergency Surgery Acuity Score (ESAS) that helps predict perioperative mortality in ES patients. METHODS: Using the 2011 American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) database (derivation cohort), we identified all surgical procedures that were classified as "emergent." A three-step methodology was then performed. First, multiple logistic regression models were created to identify independent predictors (e.g., patient demographics, comorbidities, and preoperative laboratory variables) of 30-day mortality in ES. Second, based on the relative impact of each identified predictor (i.e., odds ratio), using weighted averages, a novel score was derived. Third, using the 2012 ACS-NSQIP database (validation cohort), the score was validated by calculating its C statistic and evaluating its ability to predict 30-day mortality. RESULTS: From 280,801 NSQIP cases, 18,439 ES cases were analyzed, of which 1,598 (8.7%) resulted in death at 30 days. The multiple logistic regression analyses identified 22 independent predictors of mortality. Based on the relative impact of these predictors, ESAS was derived with a total score range of 0 to 29. ESAS had a C statistic of 0.86; the probability of death at 30 days gradually increased from 0% to 36% then 100% at scores of 0, 11, and 22, respectively. In the validation phase, 19,552 patients were included, the mortality rate was 7.2%, and the ESAS C statistic stayed at 0.86. CONCLUSION: We have therefore developed and validated a novel score, ESAS, that accurately predicts mortality in ES patients. Such a score could prove useful for (1) preoperative patient counseling, (2) identification of patients needing close postoperative monitoring, and (3) risk adjustment in any efforts at benchmarking the quality of ES.

BACKGROUND: Isolated nonoperative mild head injuries (INOMHI) occur with increasing frequency in an aging population. These patients often have multiple social, discharge, and rehabilitation issues, which far exceed the acute component of their care. This study was aimed to compare the outcomes of patients with INOMHI admitted to three services: trauma surgery, neurosurgery, and neurology. METHODS: Retrospective case series (January 1, 2009 to August 31, 2013) at an academic Level I trauma center. According to an institutional protocol, INOMHI patients with Glasgow Coma Scale (GCS) of 13 to 15 were admitted on a weekly rotational basis to trauma surgery, neurosurgery, and neurology. The three populations were compared, and the primary outcomes were survival rate to discharge, neurological status at hospital discharge as measured by the Glasgow Outcome Score (GOS), and discharge disposition. RESULTS: Four hundred eighty-eight INOMHI patients were admitted (trauma surgery, 172; neurosurgery, 131; neurology, 185). The mean age of the study population was 65.3 years, and 58.8% of patients were male. Seventy-seven percent of patients has a GCS score of 15. Age, sex, mechanism of injury, Charlson Comorbidity Index, Injury Severity Score, Abbreviated Injury Scale in head and neck, and GCS were similar among the three groups. Patients who were admitted to trauma surgery, neurosurgery and neurology services had similar proportions of survivors (98.8% vs 95.7% vs 94.7%), and discharge disposition (home, 57.0% vs 61.6% vs 55.7%). The proportion of patients with GOS of 4 or 5 on discharge was slightly higher among patients admitted to trauma (97.7% vs 93.0% vs 92.4%). In a logistic regression model adjusting for Charlson Comorbidity Index CCI and Abbreviated Injury Scale head and neck scores, patients who were admitted to neurology or neurosurgery had significantly lower odds being discharged with GOS 4 or 5. While the trauma group had the lowest proportion of repeats of brain computed tomography (61.6%), the neurosurgery group had the highest proportion of intensive care unit admission (29.8%), and the neurology group had the longest emergency department stay (7.5 hours), there were no significant differences in duration of hospital stay, in-hospital complications, and readmission within 30 days. CONCLUSIONS: Although there were differences in use of health care resources, and the proportion of patients with GOS of 4 or 5 on discharge was slightly higher among patients admitted to trauma, most clinical outcomes were similar in INOMHI patients admitted to trauma surgery, neurosurgery, or neurology in our institution. A rotational policy of admitting INOMHI patients is feasible among services with expertise in and commitment to the care of these patients. LEVEL OF EVIDENCE: Therapeutic/care management study, level IV.

BACKGROUND: The Hartford Consensus established a framework for minimizing deaths due to mass shootings, specifically eliminating preventable deaths due to limb exsanguination. Two major principles defined within this framework are (1) redefining the first responder role and (2) the ubiquitous availability of proper training in application of hemorrhage control techniques, including tourniquets. We hypothesized that this hemorrhage control posture could be fully translated into an elementary school. METHODS: Following institutional review board approval, all teachers at a prekindergarten through 8th grade elementary school underwent short, intensive instruction on their role as a first responder, as well as indications and proper technique for hemorrhage control and tourniquet application for limb exsanguination. All teachers self-reported their confidence in their role as a first responder as well as tourniquet application indications and technique before and after instruction. Following instruction, teachers were evaluated on proper tourniquet application technique on a simulated limb to assess competence. RESULTS: 26 elementary school teachers and 2 administrative staff underwent training. All reported low confidence in their role as a first responder and in tourniquet application indication and technique before training. Following training, all teachers reported high confidence. Testing demonstrated all teachers were competent in the tourniquet application technique. Following training, each classroom was equipped with a purpose-made commercial tourniquet, and a dedicated hemorrhage control bag was placed in the school's central administrative office. CONCLUSIONS: All teachers were successfully trained to act as first responders and in correct hemorrhage control techniques, which was verified by testing. This is the first elementary school to universally adopt a hemorrhage control posture to eliminate preventable deaths from limb exsanguination advocated by the Hartford Consensus.
