RESUMEN
PURPOSE: Tourniquets are a mainstay of life-saving hemorrhage control. The US military has documented the safety and effectiveness of tourniquet use in combat settings. In civilian settings, events such as the Boston Marathon bombing and mass shootings show that tourniquets are necessary and life-saving entities that must be used correctly and whenever indicated. Much less research has been done on tourniquet use in civilian settings compared to military settings. The purpose of this study is to describe the prehospital use of tourniquets in a regional EMS system served by a single trauma center. METHODS: All documented cases of prehospital tourniquet use from 2015 to 2020 were identified via a search of EMS, emergency department, and inpatient records, and reviewed by the lead investigator. The primary outcomes were duration of tourniquet placement, success of hemorrhage control, and complications; secondary outcomes included time of day (by EMS arrival time), transport interval, extremity involved, who placed/removed the tourniquet, and mechanism of injury. RESULTS: Of 182 patients with 185 tourniquets applied, duration of application was available for 52, with a median (IQR) of 43 (56) minutes. Hemorrhage control was achieved in all but two cases (96%). Three cases (5.8%) required more than one tourniquet. Complications included five cases of temporary paresthesia, one case of ecchymosis, two cases of fasciotomy, and two cases of compression nerve injury. The serious complication rate was 7.7% (4/52). Time of day was daytime (08:01-16:00) = 15 (31.9%), evening (16:01-00:00) = 27 (57.4%), and night (00:01- 08:00) = 5 (10.6%). The median transport interval was 22 (IQR 5] minutes. The limbs most often injured were the left and right upper extremities (15 each). EMS clinicians and police officers were most often the tourniquet placers. Common mechanisms of injury included gunshot wounds, motorcycle accidents, and glass injuries. CONCLUSION: Tourniquets used in the prehospital setting have a high rate of hemorrhage control and a low rate of complications.

INTRODUCTION: Alcohol use remains a significant contributing factor in traumatic injuries in the United States, resulting in substantial patient morbidity and societal cost. Because of this, the American College of Surgeons Verification, Review, and Consultation Program requires the screening of 80% of trauma admissions. Multiple studies suggest that patients who use alcohol are subject to stigma by health care providers and may ultimately face legal and financial ramifications of a positive alcohol screening test. There is also evidence that sociodemographic factors may dictate drug and alcohol screening patterns among patients. Because this screening target is often not uniformly achieved among all patients presenting with injury, we sought to investigate whether there are any discrepancies in screening across sociodemographic groups. METHODS: We investigated the Trauma Quality Program Participant User File for all trauma cases admitted during 2017 and compared the rates of the serum alcohol screening test across different demographic factors, including race and ethnicity. We then performed an adjusted multivariable logistic regression to determine the odds ratio (OR) for receiving a test based on these demographic factors adjusted for hospital and clinical factors. RESULTS: There were 729,174 traumas included in the study. Of this group, 345,315 (47.4%) were screened with a serum alcohol test. Screening rates varied by injury mechanism and were highest among motorcycle crashes (66.0% of patients screened) and lowest among falls (32.8% of patients screened). Overall, Asian and Pacific Islander (52.5% screened), Black (57.7% screened), and other race (58.4% screened) had higher rates of alcohol screening than White patients (43.7% screened, P < 0.001). Similarly, Hispanic patients were screened at higher rates than non-Hispanic patients (56.4% screening versus 46.2% screening, P < 0.001). These differences persisted across nearly all injury categories. In multivariable logistic regression, Asian and Pacific Islanders were associated with the highest odds of being screened (OR 1.34, P < 0.001) followed by other race (OR 1.25, P < 0.001) in comparison to White patients. CONCLUSIONS: There are consistent and significant differences in alcohol screening rates across race and ethnicity, despite accounting for injury mechanism and comorbidities.

BACKGROUND: We aimed to examine the clinical value of serial MRSA surveillance cultures to rule out a MRSA diagnosis on subsequent cultures during a patient's surgical intensive care unit (SICU) admission. MATERIAL AND METHODS: We performed a retrospective cohort study to evaluate patients who received a MRSA surveillance culture at admission to the SICU (n = 6,915) and collected and assessed all patient cultures for MRSA positivity during their admission. The primary objective was to evaluate the transition from a MRSA negative surveillance on admission to MRSA positive on any subsequent culture during a patient's SICU stay. Percent of MRSA positive cultures by type following MRSA negative surveillance cultures was further analyzed. MEASUREMENTS AND MAIN RESULTS: 6,303 patients received MRSA nasal surveillance cultures at admission with 21,597 clinical cultures and 7,269 MRSA surveillance cultures. Of the 6,163 patients with an initial negative, 53 patients (0.87%) transitioned to MRSA positive. Of the 139 patients with an initial positive, 30 (21.6%) had subsequent MRSA positive cultures. Individuals who had an initial MRSA surveillance positive status on admission predicted MRSA positivity rates for cultures in qualitative lower respiratory cultures (64.3% versus. 3.1%), superficial wound (60.0% versus 1.6%), deep wound (39.0% versus 0.8%), tissue culture (26.3% versus 0.6%), and body fluid (20.8% versus 0.7%) cultures when compared to MRSA negative patients on admission. CONCLUSION: Following MRSA negative nasal surveillance cultures patients showed low likelihood of MRSA infection suggesting empiric anti-MRSA treatment is unnecessary for specific patient populations. SICU patient's MRSA status at admission should guide empiric anti-MRSA therapy.

INTRODUCTION: Anticoagulation (AC) is associated with worse outcomes after trauma in some but not all studies. To further investigate the effect of AC on outcomes in patients with splenic injury, we analyzed the Trauma Quality Programs Participant Use File (PUF) METHODS: The 2017 PUF was used to identify adult (18+ y) with all mechanisms and grades of splenic injury. Demographics, comorbidities, hospital course and outcomes were compared between AC and non-AC patients. RESULTS: A total of 18,749 patients were included, 622 were on AC. The AC patients were older but had comparable gender composition to non-AC patients. Injury Severity Score (18.2 versus 22.5) and rates of serious (AIS ≥ 3) injury were all lower in the AC group (P = 0.001). AC patients received fewer units of RBC (5.7 versus 8.0 units, P < 0.001) and FFP (3.9 versus 5.4 units, P < 0.001) in the first 24 h but underwent angiography at similar rates (23.6 versus 24.5%, P = 0.8). Among those who underwent angiography, patients were more likely to undergo embolization if they were on AC (89.7 versus 73.9%, P = 0.04). Rates of splenic surgery were comparable (19.3 versus 21.5%, P = 0.2) between AC versus non-AC patients. Median LOS was longer in AC patients (6.3 versus 5.6 d, P = 0.002). AC patients had a higher mortality (13.3 versus 7.0%, P = 0.001). In a multivariable binary logistic regression, AC was an independent risk factor for mortality with OR 1.4 (95% CI: 1.1-1.9) CONCLUSIONS: Anticoagulation is associated with increased mortality in patients with splenic injury.

BACKGROUND: Patients on warfarin with traumatic intracranial hemorrhage often have the warfarin effects pharmacologically reversed. We compared outcomes among patients who received 4-factor prothrombin complex concentrate (PCC), fresh frozen plasma (FFP), or no reversal to assess the real-world impact of PCC on elderly patients with traumatic intracranial hemorrhage (ICH). MATERIALS AND METHODS: This was a retrospective analysis of 150 patients on preinjury warfarin. Data were manually abstracted from the electronic medical record of an academic level 1 trauma center for patients admitted between January 2013 and December 2018. Outcomes were ICH progression on follow-up computed tomography scan, mortality, need for surgical intervention, and trends in the use of reversal agents. RESULTS: Of 150 patients eligible for analysis, 41 received FFP, 60 PCC, and 49 were not reversed. On multivariable analysis, patients not reversed [OR 0.25 95% CI (0.31-0.85)] and women [OR 0.38 95% CI (0.17-0.88)] were less likely to experience progression of their initial bleed on follow-up computed tomography while subdural hemorrhage increased the risk [OR 3.69 95% CI (1.27-10.73)]. There was no difference between groups in terms of mortality or need for surgery. Over time use of reversal with PCC increased while use of FFP and not reversing warfarin declined (P < 0.001). CONCLUSIONS: Male gender and using a reversal agent were associated with progression of ICH. Choice of reversal did not impact the need for surgery, hospital length of stay, or mortality. Some ICH patients may not require warfarin reversal and may bias studies, especially retrospective studies of warfarin reversal.

OBJECTIVE: Patients may call urgent care centers (UCCs) with urgent surgical conditions but may not be properly referred to a higher level of care. This study aims to characterize how UCCs manage Medicaid and privately insured patients who present with an emergent condition. METHODS: Using a standardized script, we called 1245 randomly selected UCCs in 50 states on 2 occasions. Investigators posed as either a Medicaid or a privately-insured patient with symptoms of an incarcerated inguinal hernia. Rates of direct emergency department (ED) referral were compared between insurance types. RESULTS: A total of 1223 (98.2%) UCCs accepted private insurance and 981 (78.8%) accepted Medicaid. At the 971 (78.0%) UCCs that accepted both insurance types, direct-to-ED referral rates for private and Medicaid patients were 27.9% and 33.8%, respectively. Medicaid patients were significantly more likely than private patients to be referred to the ED [odds ratio (OR) 1.32, 95% confidence interval (CI) 1.09-1.60]. Private patients who were triaged by a clinician compared to nonclinician staff were over 6 times more likely to be referred to the ED (OR 6.46, 95% CI 4.63-9.01). Medicaid patients were nearly 9 times more likely to have an ED referral when triaged by a clinician (OR 8.72, 95% CI 6.19-12.29). CONCLUSIONS: Only one-third of UCCs across the United States referred an apparent emergent surgical case to the ED, potentially delaying care. Medicaid patients were more likely to be referred directly to the ED versus privately insured patients. All patients triaged by clinicians were significantly more likely to be referred to the ED; however, the disparity between private and Medicaid patients remained.

OBJECTIVE: This study aimed to answer 2 questions: first, to what degree does hospital operative volume affect mortality for adult patients undergoing 1 of 10 common emergency general surgery (EGS) operations? Second, at what hospital operative volume threshold will nearly all patients undergoing an emergency operation realize the average mortality risk? BACKGROUND: Nontrauma surgical emergencies are an underappreciated public health crisis in the United States; redefining where such emergencies are managed may improve outcomes. The field of trauma surgery established regionalized systems of care in part because studies demonstrated a clear relationship between hospital volume and survival for traumatic emergencies. Such a relationship has not been well-studied for nontrauma surgical emergencies. METHODS: Retrospective cohort study of all acute care hospitals in California performing nontrauma surgical emergencies. We employed a novel use of an ecological analysis with beta regression to investigate the relationship between hospital operative volume and mortality. RESULTS: A total of 425 acute care hospitals in California performed 165,123 EGS operations. Risk-adjusted mortality significantly decreased as volume increased for all 10 EGS operations (P < 0.001 for each); the relative magnitude of this inverse relationship differed substantially by procedure. Hospital operative volume thresholds were defined and varied by operation: from 75 cases over 2 years for cholecystectomy to 7 cases for umbilical hernia repair. CONCLUSIONS: Survival rates for nontrauma surgical emergencies were improved when operations were performed at higher-volume hospitals. The use of ecological analysis is widely applicable to the field of surgical outcomes research.
RESUMEN
OBJECTIVE: To identify the association between insurance status and the probability of emergency department admission versus transfer for patients with major injuries (Injury Severity Score >15) and other complex trauma likely to require higher-level trauma center (TC) care across the spectrum of TC care. BACKGROUND: Trauma systems were developed to facilitate direct transport and transfer of patients with major/complex traumatic injuries to designated TCs. Emerging literature suggests that uninsured patients are more likely to be transferred. METHODS: Nationally weighted Nationwide Emergency Department Sample (2010-2014) and longitudinal California State Inpatient Databases/State Emergency Department Databases (2009-2011) data identified adult (18-64 yr), pediatric (≤17 yr), and older adult (≥65 yr) trauma patients. Risk-adjusted multilevel (mixed-effects) logistic regression determined differences in the relative odds of direct admission versus transfer and outcome measures based on initial level of TC presentation. RESULTS: In all 3 age groups, insured patients were more likely to be admitted [eg, nontrauma center (NTC) private vs uninsured odds ratio (95% confidence interval): adult 1.54 (1.40-1.70), pediatric 1.95(1.45-2.61)]. The trend persisted within levels III and II TCs (eg, level II private vs uninsured adult 1.83 (1.30-2.57)] and among other forms of trauma likely to require transfer. At the state level, among transferred NTC patients, 28.5% (adult), 34.1% (pediatric), and 39.5% (older adult) of patients with major injuries were not transferred to level I/II TCs. An additional 44.3% (adult), 50.9% (pediatric), and 57.6% (older adult) of all NTC patients were never transferred. Directly admitted patients experienced higher morbidity [adult: 19.6% vs 8.2%, odds ratio (95% confidence interval):2.74 (2.17-3.46)] and mortality [3.3% vs 1.8%, 1.85 (1.13-3.04)]. CONCLUSIONS: Insured patients with significant injuries initially evaluated at NTCs and level III/II TCs were less likely to be transferred. Such a finding appears to result in less optimal trauma care for better-insured patients and questions the success of transfer-guideline implementation.

ABSTRACT: Acute pancreatitis and management of its complications is a common consult for the acute care surgeon. With the ongoing development of both operative and endoscopic treatment modalities, management recommendations continue to evolve. We describe the current diagnostic and treatment guidelines for acute pancreatitis through the lens of acute care surgery. Topics, including optimal nutrition, timing of cholecystectomy in gallstone pancreatitis, and the management of peripancreatic fluid collections, are discussed. Although the management severe acute pancreatitis can include advanced interventional modalities including endoscopic, percutaneous, and surgical debridement, the initial management of acute pancreatitis includes fluid resuscitation, early enteral nutrition, and close monitoring with consideration of cross-sectional imaging and antibiotics in the setting of suspected superimposed infection. Several scoring systems including the Revised Atlanta Criteria, the Bedside Index for Severity in Acute Pancreatitis score, and the American Association for the Surgery of Trauma grade have been devised to classify and predict the development of the severe acute pancreatitis. In biliary pancreatitis, cholecystectomy prior to discharge is recommended in mild disease and within 8 weeks of necrotizing pancreatitis, while early peripancreatic fluid collections should be managed without intervention. Underlying infection or ongoing symptoms warrant delayed intervention with technique selection dependent on local expertise, anatomic location of the fluid collection, and the specific clinical scenario. Landmark trials have shifted therapy from maximally invasive necrosectomy to more minimally invasive step-up approaches. The acute care surgeon should maintain a skill set that includes these minimally invasive techniques to successfully manage these patients. Overall, the management of acute pancreatitis for the acute care surgeon requires a strong understanding of both the clinical decisions and the options for intervention should this be necessary.

BACKGROUND: Emergency general surgery (EGS) involves care of a patient's often previously unknown disease in the setting of an unplanned interaction with the healthcare system. This leads to challenges collecting and interpreting patient reported outcome measures (PROMs). METHODS: We performed a qualitative and mixed methods study using semi-structured interviews during the index hospitalization and at 6-12 months to capture peri-operative patient experiences. We compared interview findings to clinical characteristics. RESULTS: Among 30 patients, two-thirds reported feeling no choice but to pursue emergency surgery with many reporting exclusion from decision-making. Females reported these themes more commonly. Patients with minor complications less frequently reported trust in their team and discussed communication issues and delays in care (all p â< â0.05). Patients with major complications more frequently reported confidence in their team and gratefulness, but also communication limitations (all p â< â0.05). Patients not admitted to the ICU more frequently discussed good communication and expeditious treatment. CONCLUSIONS: PROMs developed for EGS patients should consider patient outcomes and reflections that they felt excluded from decision-making. Severity of complications may also differentially impact PROMs.

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.

BACKGROUND: Andexanet Alfa (AA) is the only FDA approved reversal agent for apixaban and rivaroxaban (DOAC). There are no studies comparing its efficacy with 4-Factor Prothrombin Complex Concentrate (PCC). This study aimed to compare PCC to AA for DOAC reversal, hypothesizing non-inferiority of PCC. METHODS: We performed a retrospective, non-inferiority multicenter study of adult patients admitted from July 1, 2018 to December 31, 2019 who had taken a DOAC within 12 hours of injury, were transfused red blood cells (RBCs) or had traumatic brain injury, and received AA or PCC. Primary outcome was PRBC unit transfusion. Secondary outcome with ICU length of stay. MICE imputation was used to account for missing data and zero-inflated poisson regression was used to account for an excess of zero units of RBC transfused. 2 Units difference in RBC transfusion was selected as non-inferior. RESULTS: Results: From 263 patients at 10 centers, 77 (29%) received PCC and 186 (71%) AA. Patients had similar transfusion rates across reversal treatment groups (23.7% AA vs 19.5% PCC) with median transfusion in both groups of 0 RBC. According to the Poisson component, PCC increases the amount of RBC transfusion by 1.02 times (95% CI: 0.79-1.33) compared to AA after adjusting for other covariates. The averaged amount of RBC transfusion (non-zero group) is 6.13. Multiplying this number by the estimated rate ratio, PCC is estimated to have an increase RBC transfusion by 0.123 (95% CI: 0.53-2.02) units compared to AA. CONCLUSION: PCC appears non-inferior to AA for reversal of DOACs for RBC transfusion in traumatically injured patients. Additional prospective, randomized trials are necessary to compare PCC and AA for the treatment of hemorrhage in injured patients on DOACs. LEVEL OF EVIDENCE: Therapeutic/Care Management, Level III.
RESUMEN
BACKGROUND: In patients with severe traumatic brain injury (TBI), clinicians must balance preventing venous thromboembolism (VTE) with the risk of intracranial hemorrhagic expansion (ICHE). We hypothesized that low molecular weight heparin (LMWH) would not increase risk of ICHE or VTE as compared to unfractionated heparin (UH) in patients with severe TBI. METHODS: Patients ≥ 18 years of age with isolated severe TBI (AIS ≥ 3), admitted to 24 level I and II trauma centers between January 1, 2014 to December 31, 2020 and who received subcutaneous UH and LMWH injections for chemical venous thromboembolism prophylaxis (VTEP) were included. Primary outcomes were VTE and ICHE after VTEP initiation. Secondary outcomes were mortality and neurosurgical interventions. Entropy balancing (EBAL) weighted competing risk or logistic regression models were estimated for all outcomes with chemical VTEP agent as the predictor of interest. RESULTS: 984 patients received chemical VTEP, 482 UH and 502 LMWH. Patients on LMWH more often had pre-existing conditions such as liver disease (UH vs LMWH 1.7 % vs. 4.4 %, p = 0.01), and coagulopathy (UH vs LMWH 0.4 % vs. 4.2 %, p < 0.001). There were no differences in VTE or ICHE after VTEP initiation. There were no differences in neurosurgical interventions performed. There were a total of 29 VTE events (3 %) in the cohort who received VTEP. A Cox proportional hazards model with a random effect for facility demonstrated no statistically significant differences in time to VTE across the two agents (p = 0.44). The LMWH group had a 43 % lower risk of overall ICHE compared to the UH group (HR = 0.57: 95 % CI = 0.32-1.03, p = 0.062), however was not statistically significant. CONCLUSION: In this multi-center analysis, patients who received LMWH had a decreased risk of ICHE, with no differences in VTE, ICHE after VTEP initiation and neurosurgical interventions compared to those who received UH. There were no safety concerns when using LMWH compared to UH. LEVEL OF EVIDENCE: Level III, Therapeutic Care Management.

BACKGROUND: Data from the National Health Expenditure Accounts have shown a steady increase in healthcare cost paralleled by availability of laboratory tests. Resource utilization is a top priority for reducing health care costs. We hypothesized that routine post-operative laboratory utilization unnecessarily increases costs and healthcare system burden in acute appendicitis (AA) management. METHODS: A retrospective cohort of patients with uncomplicated AA 2016-2020 were identified. Clinical variables, demographics, lab usage, interventions, and costs were collected. RESULTS: A total of 3711 patients with uncomplicated AA were identified. Total costs of labs ($289,505, 99.56%) and repletions ($1287.63, 0.44%) were $290,792.63. Increased LOS was associated with lab utilization in multivariable modeling, increasing costs by $837,602 or 472.12 per patient. CONCLUSIONS: In our patient population, post-operative labs resulted in increased costs without discernible impact on clinical course. Routine post-operative laboratory testing should be re-evaluated in patients with minimal comorbidities as this likely increases cost without adding value.

Objective: To identify the rates and possible predictors of alcohol withdrawal syndrome (AWS) among adult trauma patients. Methods: This is a retrospective review of all adult patients (18 years or older) included in the 2017 and 2018 American College of Surgeons Trauma Quality Program Participant User File (PUF). The main outcomes were rates and predictors of AWS. Results: 1 677 351 adult patients were included in the analysis. AWS was reported in 11 056 (0.7%). The rate increased to 0.9% in patients admitted for more than 2 days and 1.1% in those admitted for more than 3 days. Patients with AWS were more likely to be male (82.7% vs. 60.7%, p<0.001), have a history of alcohol use disorder (AUD) (70.3% vs. 5.6%, p<0.001) and have a positive blood alcohol concentration (BAC) on admission (68.2% vs. 28.6%, p<0.001). In a multivariable logistic regression, history of AUD (OR 12.9, 95% CI 12.1 to 13.7), cirrhosis (OR 2.1, 95% CI 1.9 to 2.3), positive toxicology screen for barbiturates (OR 2.1, 95% CI 1.6 to 2.7), tricyclic antidepressants (OR 2.2, 95% CI 1.5 to 3.1) or alcohol (OR 2.5, 95% CI 2.4 to 2.7), and Abbreviated Injury Scale head score of ≥3 (OR 1.7, 95% CI 1.6 to 1.8) were the strongest predictors for AWS. Conversely, only 2.7% of patients with a positive BAC on admission, 7.6% with a history of AUD and 4.9% with cirrhosis developed AWS. Conclusion: AWS after trauma was an uncommon occurrence in the patients in the PUF, even in higher-risk patient populations. Level of evidence: IV: retrospective study with more than one negative criterion.
RESUMEN
BACKGROUND: Patients with right upper quadrant pain are often imaged using multiple modalities with no established gold standard. A single imaging study should provide adequate information for diagnosis. METHODS: A multicenter study of patients with acute cholecystitis was queried for patients who underwent multiple imaging studies on admission. Parameters were compared across studies including wall thickness (WT), common bile duct diameter (CBDD), pericholecystic fluid and signs of inflammation. Cutoff for abnormal values were 3 mm for WT and 6 mm for CBDD. Parameters were compared using chi-square tests and Intra-class correlation coefficients (ICC). RESULTS: Of 861 patients with acute cholecystitis, 759 had ultrasounds, 353 had CT and 74 had MRIs. There was excellent agreement for wall thickness (ICC = 0.733) and bile duct diameter (ICC = 0.848) between imaging studies. Differences between wall thickness and bile duct diameters were small with nearly all <1 mm. Large differences (>2 mm) were rare (<5%) for WT and CBDD. CONCLUSIONS: Imaging studies in acute cholecystitis generate equivalent results for typically measured parameters.

Background: This study aims to quantitatively assess use of the NSQIP surgical risk calculator (NSRC) in contemporary surgical practice and to identify barriers to use and potential interventions that might increase use. Materials and methods: We performed a cross-sectional study of surgeons at seven institutions. The primary outcomes were self-reported application of the calculator in general clinical practice and specific clinical scenarios as well as reported barriers to use. Results: In our sample of 99 surgeons (49.7% response rate), 73.7% reported use of the NSRC in the past month. Approximately half (51.9%) of respondents reported infrequent NSRC use (<20% of preoperative discussions), while 14.3% used it in ≥40% of preoperative assessments. Reported use was higher in nonelective cases (30.2% vs 11.1%) and in patients who were ≥65 years old (37.1% vs 13.0%), functionally dependent (41.2% vs 6.6%), or with surrogate consent (39.9% vs 20.4%). NSRC use was not associated with training status or years in practice. Respondents identified a lack of influence on the decision to pursue surgery as well as concerns regarding the calculator's accuracy as barriers to use. Surgeons suggested improving integration to workflow and better education as strategies to increase NSRC use. Conclusions: Many surgeons reported use of the NSRC, but few used it frequently. Surgeons reported more frequent use in nonelective cases and frail patients, suggesting the calculator is of greater utility for high-risk patients. Surgeons raised concerns about perceived accuracy and suggested additional education as well as integration of the calculator into the electronic health record.
RESUMEN
INTRODUCTION: The American Association for the Surgery of Trauma Colon Organ Injury Scale (OIS) was updated in 2020 to include a separate OIS for penetrating colon injuries and included imaging criteria. In this multicenter study, we describe the contemporary management and outcomes of penetrating colon injuries and hypothesize that the 2020 OIS system correlates with operative management, complications, and outcomes. METHODS: This was a retrospective study of patients presenting to 12 Level 1 trauma centers between 2016 and 2020 with penetrating colon injuries and Abbreviated Injury Scale score of <3 in other body regions. We assessed the association of the new OIS with surgical management and clinical outcomes and the association of OIS imaging criteria with operative criteria. Bivariate analysis was done with χ 2 , analysis of variance, and Kruskal-Wallis, where appropriate. Multivariable models were constructed in a stepwise selection fashion. RESULTS: We identified 573 patients with penetrating colon injuries. Patients were young and predominantly male; 79% suffered a gunshot injury, 11% had a grade V destructive injury, 19% required ≥6 U of transfusion, 24% had an Injury Severity Score of >15, and 42% had moderate-to-large contamination. Higher OIS was independently associated with a lower likelihood of primary repair, higher likelihood of resection with anastomosis and/or diversion, need for damage-control laparotomy, and higher incidence of abscess, wound infection, extra-abdominal infections, acute kidney injury, and lung injury. Damage control was independently associated with diversion and intra-abdominal and extra-abdominal infections. Preoperative imaging in 152 (27%) cases had a low correlation with operative findings ( κ coefficient, 0.13). CONCLUSION: This is the largest study to date of penetrating colon injuries and the first multicenter validation of the new OIS specific to these injuries. While imaging criteria alone lacked strong predictive value, operative American Association for the Surgery of Trauma OIS colon grade strongly predicted type of interventions and outcomes, supporting use of this grading scale for research and clinical practice. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

BACKGROUND: Nonoperative management of acute appendicitis is increasingly common. However, small studies have demonstrated high rates of appendiceal cancer in interval appendectomy specimens. Therefore, we sought to identify national trends in appendiceal cancer incidence and histology. STUDY DESIGN: The National Cancer Database was queried for patients 18 years or older, diagnosed with a right-sided colon cancer (including appendiceal) from 2004 to 2017 who had undergone surgery. Outcomes included trends in appendiceal cancer compared with right-sided colon cancers and trends in appendiceal cancer histology. Logistic regression was used to assess trends over time while adjusting for patient age, insurance, income, area of residence, and comorbidity. Predicted probabilities of the outcomes were derived from the logistic regression models. RESULTS: Of 387,867 patients with right-sided colon cancer, 19,570 had appendiceal cancer and of those 5,628 had a carcinoid tumor. Odds of appendiceal cancer, relative to other right-sided colon cancers, increased from 2004 to 2017 (odds ratio [OR] 2.56, 95% CI 2.35-2.79). The increase occurred in all age groups; however, it was more markedly increased in patients 40-49 years old (2004: 10%, 95% CI 9-12 to 2017: 18%, 95% CI 16-20; pairwise comparisons p < 0.001). Odds of appendiceal carcinoid, relative to other appendiceal histologies, increased from 2004 to 2017 (OR 1.70, 95% CI 1.40-2.07) with the greatest increase in probability of a carcinoid in patients younger than 40 years old (2004: 24%, 95% CI 15-34 to 2017: 45%, 95% CI 37-53; pairwise comparisons p < 0.001). CONCLUSION: Appendiceal cancer has increased over time, and the increase appears to be driven by a rise in carcinoids, most prevalent in patients 49 years of age or younger. When nonoperative management of acute appendicitis is undertaken, close follow-up may be appropriate given these findings.
