RESUMO
OBJECTIVES: Literature is emerging regarding the role of center volume as an independent variable contributing to improved outcomes. A higher volume of index procedures may be associated with decreased morbidity and mortality. This association has not been examined for the subgroup of infants with congenital diaphragmatic hernia (CDH) receiving extracorporeal life support (ECLS). Our study aims to examine the risk-adjusted association between center volume and outcomes in CDH-ECLS neonates, hypothesizing that higher center volume confers a survival advantage. DESIGN: Multicenter, retrospective comparative study using the Extracorporeal Life Support Organization database. SETTING: One hundred twenty international pediatric centers. PATIENTS: Neonates with CDH managed with ECLS from 2000 to 2019. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The cohort included 4,985 neonates with a mortality rate of 50.6%. For the 120 centers studied, mean center volume was 42.4 ± 34.6 CDH ECLS cases over the 20-year study period. In an adjusted model, higher ECLS volume was associated with lower odds of mortality: odds ratio (OR) 0.995 (95% CI, 0.992-0.999; p = 0.014). For an increase in one sd in volume, that is, 1.75 cases annually, the OR for mortality was lower by 16.7%. Volume was examined as a categorical exposure variable where low-volume centers (fewer than 2 cases/yr) were associated with 54% higher odds of mortality (OR, 1.54; 95% CI, 1.03-2.29) compared with high-volume centers. On-ECLS complications (mechanical, neurologic, cardiac, hematologic metabolic, and renal) were not associated with volume. The likelihood of infectious complications was higher for low- (OR, 1.90; 95% CI, 1.06-3.40) and medium-volume (OR, 1.87; 95% CI, 1.03-3.39) compared with high-volume centers. CONCLUSIONS: In this study, a survival advantage directly proportional to center volume was observed for CDH patients managed with ECLS. There was no significant difference in most complication rates. Future studies should aim to identify factors contributing to the higher mortality and morbidity observed at low-volume centers.

BACKGROUND: Teaching hospitals are often regarded as excellent institutions with significant resources and prominent academic faculty. However, the involvement of trainees may contribute to higher rates of complications. Conflicting reports exist regarding outcomes between teaching and nonteaching hospitals, and the difference among trauma centers is unknown. We hypothesized that university teaching trauma centers (UTTCs) and nonteaching trauma centers (NTTCs) would have a similar risk of complications and mortality. METHODS: We queried the Trauma Quality Improvement Program (2010-2016) for adults treated at UTTCs or NTTCs. A multivariable logistic regression analysis was performed to evaluate the risk of mortality and in-hospital complications, such as respiratory complications (RCs), venous thromboembolisms (VTEs), and infectious complications (ICs). RESULTS: From 895,896 patients, 765,802 (85%) were treated at UTTCs and 130,094 (15%) at NTTCs. After adjusting for covariates, UTTCs were associated with an increased risk of RCs (odds ratio (OR) 1.33, confidence interval (CI) 1.28-1.37, P < 0.001), VTEs (OR 1.17, CI 1.12-1.23, P < 0.001), and ICs (OR 1.56, CI 1.49-1.64, P < 0.001). However, UTTCs were associated with decreased mortality (OR 0.96, CI 0.93-0.99, P = 0.008) compared with NTTCs. CONCLUSIONS: Our study demonstrates increased associated risks of RCs, VTEs, and ICs, yet a decreased associated risk of in-hospital mortality for UTTCs when compared with NTTCs. Future studies are needed to identify the underlying causative factors behind these differences.

BACKGROUND: Neonates receiving extracorporeal life support (ECLS) for congenital diaphragmatic hernia (CDH) require prolonged support compared with neonates with other forms of respiratory failure. Hemolysis is a complication that can be seen during ECLS and can lead to renal failure and potentially to worse outcomes. The purpose of this study was to identify risk factors for the development of hemolysis in CDH patients treated with ECLS. METHODS: The Extracorporeal Life Support Organization database was used to identify infants with CDH (2000-2015). The primary outcome was hemolysis (plasma-free hemoglobin >50 mg/dL). Potentially associated variables were identified in the data set. Descriptive statistics and a series of nested multivariable logistic regression models were used to identify associations between hemolysis and demographic, pre-ECLS, and on-ECLS factors. RESULTS: There were 4576 infants with a mortality of 52.5%. The overall mean rate of hemolysis was 10.5% during the study period. In earlier years (2000-2005), the hemolysis rates were 6.3% and 52.7% for roller versus centrifugal pumps, whereas in later years (2010-2015), they were 2.9% and 26.5%, respectively. The fully adjusted model demonstrated that the use of centrifugal pumps was a strong predictor of hemolysis (odds ratio: 6.67, 95% confidence interval: 5.14-8.67). In addition, other risk factors for hemolysis included low 5-min Apgar score, on-ECLS complications (renal, metabolic, and cardiovascular), and duration of ECLS. CONCLUSIONS: In our cohort of CDH patients receiving ECLS over 15 y, the use of centrifugal pumps increased over time, along with the rate of hemolysis. Patient- and treatment-level risk factors were identified contributing to the development of hemolysis.

OBJECTIVE: Study incidence and mortality for blunt trauma patients developing acute respiratory distress syndrome (ARDS) across race and insurance. DESIGN: The National Trauma Data Bank (2007-2015) was queried for blunt trauma patients age >16. Covariates (age >65, injury severity score [ISS] >25, traumatic brain injury, lung injury, pneumonia, severe sepsis, hypotension on admission, and blood transfusion) were included in a multivariable logistic regression analysis. SETTING: Despite progress in the treatment for ARDS, it remains a significant concern. Racial differences in response to trauma and ARDS have been inconsistently demonstrated. Since these prior studies, ARDS has been redefined by the Berlin Criteria, advances in care have been made, and health-care accessibility has changed. PATIENTS: Adult blunt trauma patients with ISS > 15 and length of stay ≥ 3 days to examine patients at high risk of ARDS. MEASUREMENTS AND MAIN RESULTS: There were 28 727 patients with ARDS. Most were white (76.2%), followed by blacks (11.5%), Hispanics (11.3%), and Asians (1.8%). Overall mortality was 20.5%. Compared to whites, blacks (odds ratio [OR]: 1.15, confidence interval [CI]: 1.10-1.20, P < .001) had higher risk of ARDS, being Hispanic was protective (OR: 0.80, CI: 0.76-0.83, P < .001). Asians with ARDS were at greater risk of death (OR: 1.31, CI: 1.07-1.61, P < .05) while being black was not associated with risk of death. Patients with private insurance had less diagnosed ARDS and those with ARDS had lower mortality than other insurances (OR: 0.86, CI: 0.79-0.92, P < .001). CONCLUSIONS: Data from the National Trauma Data Bank (2007-2015) demonstrates racial and insurance disparities in the development of ARDS in blunt trauma patients. When compared to whites, blacks are at higher risk of developing ARDS while being Hispanic is protective. Likewise, Asians are at greatest risk of death and blacks have no difference in mortality when compared to whites. Patients with private insurance have lower risk of incidence and mortality.

OBJECTIVES: The Centers for Disease Control disclosed over 600,000 cases of child abuse or neglect in 2016. Single-institution studies have shown that nonaccidental trauma (NAT) has higher complication rates than accidental trauma (AT). Nonaccidental trauma is disproportionately represented in infants. We hypothesized that NAT would increase the risk of mortality in infants. This study aims to provide a contemporary descriptive analysis for infant trauma patients and determine the association between NAT and mortality. METHODS: Infants (<1 year of age) within the Pediatric Trauma Quality Improvement Program database (2014-2016) were identified. Descriptive statistics (χ2 and t test) were used to compare NAT infants to AT infants. A multivariable logistic regression was used to determine the risk of mortality associated with select variables including NAT. RESULTS: From 14,965 infant traumas, most presented to a level I pediatric trauma center (53.5%) with a median injury severity score of 9. The most common mechanism was falls (48.6%), followed by NAT (14.5%). Overall mortality was 2.1%. Although most NAT infants were white (60.2%), black infants were overrepresented (23.6% vs 18.3%; P < 0.0001) compared with AT infants. The incidence of mortality was higher in NAT infants (41.6% vs 13.9%; P < 0.0001), and they were more likely to have traumatic brain injury (TBI) (63.1% vs 50.6%; P < 0.001). Nonaccidental trauma [odds ratio (OR), 2.48; P < 0.001], hypotension within 24 hours (OR, 8.93; P < 0.001), injury severity score (OR, 1.12; P < 0.001), and severe abbreviated injury scale-head (OR 1.62, P = 0.014) had the highest association with mortality. CONCLUSIONS: This study confirms the incidence of TBI and NAT in infants. Although providers should be vigilant for NAT, suspicion of NAT should prompt close surveillance, as there is a 2-fold increased risk of mortality independent of injury or TBI.

BACKGROUND: Pediatric patients admitted for trauma may have unique risk factors of unplanned readmission and require condition-specific models to maximize accuracy of prediction. We used a multicenter data set on trauma admissions to study risk factors and predict unplanned 7-day readmissions with comparison to the 30-day metric. METHODS: Data from 28 hospitals in the United States consisting of 82,532 patients (95,158 encounters) were retrieved, and 75% of the data were used for building a random intercept, mixed-effects regression model, whereas the remaining were used for evaluating model performance. The variables included were demographics, payer, current and past health care utilization, trauma-related and other diagnoses, medications, and surgical procedures. RESULTS: Certain conditions such as poisoning and medical/surgical complications during treatment of traumatic injuries are associated with increased odds of unplanned readmission. Conversely, trauma-related conditions, such as trauma to the thorax, knee, lower leg, hip/thigh, elbow/forearm, and shoulder/upper arm, are associated with reduced odds of readmission. Additional predictors include the current and past health care utilization and the number of medications. The corresponding 7-day model achieved an area under the receiver operator characteristic curve of 0.737 (0.716, 0.757) on an independent test set and shared similar risk factors with the 30-day version. CONCLUSIONS: Patients with trauma-related conditions have risk of readmission modified by the type of trauma. As a result, additional quality of care measures may be required for patients with trauma-related conditions that elevate their risk of readmission.

PURPOSE: Intraoperative chest tubes (IOCTs) can be placed during esophageal atresia/tracheoesophageal fistula (EA/TEF) repair to control pneumothoraces and detect esophageal leaks, potentially preventing the need for postoperative chest tubes (POCTs). However, data are lacking regarding IOCTs' effect. We hypothesized that IOCT placement would not reduce the risk of POCT placement and would increase hospital length of stay (LOS). METHODS: This was a single-center case-control study of type C EA/TEF patients repaired at a tertiary referral center between 2006 and 2017. Postoperative complications of patients who received IOCTs (n = 83) were compared to that of patients who did not receive IOCTs (n = 26). Patients were compared via propensity score matching. Additionally, sensitivity analyses excluding low birth weight (LBW) patients and patients undergoing delayed esophageal anastomosis were also performed. RESULTS: There was no significant difference in rates of pneumothoraces or esophageal leaks between the IOCT and no-IOCT groups, nor were either of these complications detected earlier in the IOCT group. Rates of POCT placement and mortality also did not differ between groups. IOCT patients were associated with increased hospital LOS (28 vs 15.5 days, p < 0.001) and esophageal strictures (30% vs 8%, p = 0.04) requiring a return to the operating room (RTOR). CONCLUSION: IOCTs did not improve outcomes in EA/TEF repair. IOCTs seem associated with increased LOS and ROTR for esophageal stricture, suggesting that IOCTs may not be beneficial after EA/TEF repair.

BACKGROUND: Utilization of ICP monitors for pediatric patients is low and varies between centers. We hypothesized that in more severely injured patients (GCS 3-4), there would be a decreased mortality associated with invasive monitoring devices. METHODS: The pediatric Trauma Quality Improvement Program (TQIP) was queried for patients aged ≤ 16 years meeting criteria for invasive monitors. Our primary outcome was mortality. Patients with ICP monitoring were compared to those without. A logistic regression was used to examine the risk of mortality. RESULTS: Of 3,808 patients, 685 (18.0%) underwent ICP monitoring. ICP monitors were associated with increased risk of mortality (OR 1.82, CI 1.36-2.44, p < 0.001). A secondary analysis including type of invasive ICP monitor and dividing GCS into 3 categories revealed both intraventricular drain (OR 1.89, CI 1.3-2.7, p = 0.001) and intraparenchymal pressure monitor (OR 1.86, CI 1.32-2.6, p < 0.001) to be independently associated with an increased likelihood of mortality regardless of GCS, while intraparenchymal oxygen monitoring was not (OR 0.47, CI 0.11-2.05, p = 0.316). The strongest effect was seen in those patients with a GCS of 5-6. CONCLUSION: ICP monitors are an independent risk factor for mortality, particularly with intraventricular drains and intraparenchymal monitors in patients with a GCS 5-6.

BACKGROUND/PURPOSE: Perioperative blood transfusion is common after pancreaticoduodenectomy (PD) and may predispose patients to infectious complications. The purpose of this study is to examine the association between perioperative blood transfusion and the development of post-surgical infection after PD. METHODS: Patients who underwent PD from 2014 to 2015 were identified in the NSQIP pancreas-specific database. Logistic regression analysis was used to compute adjusted odds ratios (aOR) to identify an independent association between perioperative red blood cell transfusion (within 72 h of surgery) and the development of post-operative infection after 72 h. RESULTS: A total of 6869 patients underwent PD during this time period. Of these, 1372 (20.0%) patients received a perioperative blood transfusion. Patients receiving transfusion had a higher rate of post-operative infection (34.7% vs 26.5%, p < 0.001). After adjusting for significant covariates, perioperative transfusion was independently associated the subsequent development of any post-operative infection (aOR 1.41 [1.23-1.62], p < 0.001), including pneumonia (aOR 2.01 [1.48-2.74], p < 0.001), sepsis (aOR 1.62 [1.29-2.04], p < 0.001), and septic shock (aOR 1.92 [1.38-2.68], p < 0.001). CONCLUSION: There is a strong independent association between perioperative blood transfusion and the development of subsequent post-operative infection following PD.

PURPOSE OF REVIEW: Necrotizing enterocolitis (NEC) is a devastating disease that predominately affects premature neonates. The pathogenesis of NEC is multifactorial and poorly understood. Risk factors include low birth weight, formula-feeding, hypoxic/ischemic insults, and microbial dysbiosis. This review focuses on our current understanding of the diagnosis, management, and pathogenesis of NEC. RECENT FINDINGS: Recent findings identify specific mucosal cell types as potential therapeutic targets in NEC. Despite a broadly accepted view that bacterial colonization plays a key role in NEC, characteristics of bacterial populations associated with this disease remain elusive. The use of probiotics such as lactobacilli and bifidobacteria has been studied in numerous trials, but there is a lack of consensus regarding specific strains and dosing. Although growth factors found in breast milk such as epidermal growth factor and heparin-binding epidermal growth factor may be useful in disease prevention, developing new therapeutic interventions in NEC critically depends on better understanding of its pathogenesis. SUMMARY: NEC is a leading cause of morbidity and mortality in premature neonates. Recent data confirm that growth factors and certain bacteria may offer protection against NEC. Further studies are needed to better understand the complex pathogenesis of NEC.

PURPOSE: With the exception of neonatal respiratory failure, most centers are now using centrifugal over roller-type pumps for the delivery of extracorporeal membrane oxygenation (ECMO). Evidence supporting the use of centrifugal pumps specifically in infants with congenital diaphragmatic hernia (CDH) remains lacking. We hypothesized that the use of centrifugal pumps in infants with CDH would not affect mortality or rates of severe neurologic injury (SNI). METHODS: Infants with CDH were identified within the ELSO registry (2000-2016). Patients were then divided into those undergoing ECMO with rollertype pumps or centrifugal pumps. Patients were matched based on propensity score (PS) for the ECMO pump type based on pre-ECMO covariates. This was done for all infants and separately for each ECMO mode, venovenous (VV) and venoarterial (VA) ECMO. RESULTS: We identified 4,367 infants who were treated with either roller or centrifugal pumps from 2000-2016. There was no difference in mortality or SNI between the two pump types in any of the groups (all infants, VA-ECMO infants, VV-ECMO infants). However, there was at least a six-fold increase in the odds of hemolysis for centrifugal pumps in all groups: all infants (odds ratio [OR] 6.99, p<0.001), VA-ECMO infants (OR 8.11, p<0.001 and VV-ECMO infants (OR 9.66, p<0.001). CONCLUSION: For neonates with CDH requiring ECMO, there is no survival advantage or difference in severe neurologic injury between those receiving roller or centrifugal pump ECMO. However, there is a significant increase in red blood cell hemolysis associated with centrifugal ECMO support.

Cloacal exstrophy is the most severe congenital anomaly of the exstrophy-epispadias complex and is characterized by gastrointestinal, genitourinary, neurospinal, and musculoskeletal malformations. Individualized surgical reconstruction by a multidisciplinary team is required for these complex patients. Not infrequently, patients need staged surgical procedures throughout childhood and adolescence. Following significant improvements in medical care and surgical reconstructive techniques, nearly all patients with cloacal exstrophy now survive, leading to an increased emphasis on quality of life. Increased attention is given to gender identity and the implications of reconstructive decisions. Long-term sequelae of cloacal exstrophy, including functional continence and sexual dysfunction, are recognized, and many patients require ongoing complex care into adulthood.
RESUMO
BACKGROUND: Open fractures have been associated with a higher risk of infection if antibiotics are not administered within 1 h of presentation in adult trauma patients. Time to antibiotic administration for open fractures is frequently used as a quality metric for trauma centers, but there have been no large studies evaluating this topic for pediatric patients. METHODS: The 2019 Trauma Quality Improvement Program dataset was queried for patients ≤ 16 years old with isolated open femur or tibia fractures undergoing operative intervention after blunt trauma. Patients transferred from another hospital were excluded. Pediatric patients receiving early antibiotics (EA) within 1 h were compared to patients receiving delayed antibiotics (DA) greater than or equal to 1 h from arrival. Multivariate logistic regression was used to evaluate risk of surgical site infection (SSI). RESULTS: There were 150 patients with open lower extremity fractures: 98 (64.9%) EA vs 52 (34.4%) DA. There was no difference in the rate of SSI between the 2 groups (EA: 1.0% vs DA: 1.9%, P = 0.65). There remained similar associated risk of infection after adjusting for lower extremity abbreviated injury scale >3, blood transfusion requirement, and vital signs on arrival (OR 0.62, 95% CI 0.04-10.24, P = 0.74). CONCLUSIONS: Most pediatric trauma patients with open lower extremity fracture received antibiotics within 1 h of presentation. However, SSI was rare and the risk of SSI was not associated with antibiotic administration within 1 h. Therefore, timing of antibiotic administration for pediatric open lower extremity fractures should be re-evaluated as a quality metric.Level of Evidence: Level III.
RESUMO
Background: Despite the high prevalence of post-operative fever, a variety of approaches are taken as to the components of a fever evaluation, when it should be undertaken, and when empiric antibiotic agents should be started. Hypothesis: There is a lack of consensus surrounding many common components of a post-operative fever evaluation. Patients and Methods: The Surgical Infection Society membership was surveyed to determine practices surrounding evaluation of post-operative fever. Eight scenarios were posed in febrile (38.5°C), post-operative general surgery or trauma patients, with 19 possible components of work-up (physical examination, complete blood count [CBC], fungal biomarkers, lactate and procalcitonin [PCT] concentrations, cultures, imaging) and management (antibiotic agents). Each scenario was then re-considered for intensive care unit (ICU) patients (intubated/unstable hemodynamics). Agreement on a parameter (<1/4 or >3/4 of respondents) achieved consensus, positive or negative. Parameters between had equipoise; α was set at 0.05. Results: Among the examined scenarios, only CBC and physical examination received positive consensus across most scenarios. Blood/urine cultures, imaging, lactate, inflammatory biomarkers, and the empiric administration of antibiotic agents did not reach consensus; support was variable depending on the clinical scenario, illness severity, and the individual preferences of the answering clinician. The qualitative portion of the survey identified "fever threshold and duration," "clinical suspicion," and "physiologic manifestation" as the most important factors for deciding about the initiation of a fever evaluation and the potential empiric administration of antibiotic agents. Conclusions: There is consensus only for physical and examination routine laboratory work when initiating the evaluation of febrile post-operative patients. However, there are multiple components of a fever evaluation that individual respondents would select depending on the clinical scenario and severity of illness. Parameters demonstrating equipoise are potential candidates for formal guidance or pragmatic prospective trials.

BACKGROUND: The abdominal seat belt sign (SBS) is associated with an increased risk of hollow viscus injury (HVI). Older age is associated with worse outcomes in trauma patients. Thus, older trauma patients ≥65 years of age (OTPs) may be at an increased risk of HVI with abdominal SBS. Therefore, we hypothesized an increased incidence of HVI and mortality for OTPs vs younger trauma patients (YTPs) with abdominal SBS. STUDY DESIGN: This post hoc analysis of a multi-institutional, prospective, observational study (8/2020-10/2021) included patients >18 years old with an abdominal SBS who underwent abdominal computed tomography (CT) imaging. Older trauma patients were compared to YTPs (18-64 years old) with bivariate analyses. RESULTS: Of the 754 patients included in this study from nine level-1 trauma centers, there were 110 (14.6%) OTPs and 644 (85.4%) YTPs. Older trauma patients were older (mean 75.3 vs 35.8 years old, P < .01) and had a higher mean Injury Severity Score (10.8 vs 9.0, P = .02). However, YTPs had an increased abdominal abbreviated-injury scale score (2.01 vs 1.63, P = .02). On CT imaging, OTPs less commonly had intraabdominal free fluid (21.7% vs 11.9%, P = .02) despite a similar rate of abdominal soft tissue contusion (P > .05). Older trauma patients also had a statistically similar rate of HVI vs YTPs (5.5% vs 9.8%, P = .15). Despite this, OTPs had increased mortality (5.5% vs 1.1%, P < .01) and length of stay (LOS) (5.9 vs 4.9 days P < .01). CONCLUSION: Despite a similar rate of HVI, OTPs with an abdominal SBS had an increased rate of mortality and LOS. This suggests the need for heightened vigilance when caring for OTPs with abdominal SBS.
RESUMO
Background: Many techniques for closure of surgical incisions are available to the surgeon, but there is minimal guidance regarding which technique(s) should be utilized at the conclusion of surgery and under what circumstances. Hypothesis: Management of incisions at the conclusion of surgery lacks consensus and varies among individual surgeons. Methods: The Surgical Infection Society membership was surveyed on the management of incisions at the conclusion of surgery. Several case scenarios were provided to test the influences of operation type, intra-operative contamination, and hemodynamic stability on incision management (e.g., close fascia or skin, use of incision/wound vacuum-assisted closure [VAC] device). Responses by two-thirds of participants were required to achieve consensus. Data analysis by χ2 test and logistic regression, a = 0.05. Response heterogeneity was quantified by the Shannon index (SI). Results: Among 78 respondents, consensus was achieved for elective splenectomy (91% close skin/dry dressing). Open appendectomy and left colectomy/end-colostomy had the greatest heterogeneity (SI, 1.68 and 1.63, respectively). During trauma laparotomy, the majority used damage control for hemodynamic instability (53%-67%) but not for hemodynamically stable patients (0%-1.3%; p < 0.001). Additional consensus was achieved for close skin/dry dressing for hemodynamically stable trauma splenectomy patients (87%) and fascia open/wound VAC for hemodynamically unstable colon resection/anastomosis (67%). Fecal diversion for rectal injury and colon resection/anastomosis (both when hemodynamically stable) had high heterogeneity (SI, 1.56 and 1.48, respectively). In penetrating trauma, sentiment was for more use of wet-to-dry dressings and incision/wound VAC with increased contamination in hemodynamically stable patients. Conclusions: Damage control was favored in hemodynamically unstable trauma patients, with use of wet-to-dry dressings and incision/wound VAC with spillage after penetrating trauma. However, most scenarios did not achieve consensus. High variability of practices regarding incision management at the conclusion of surgery was confirmed. Prospective studies and evidence-based guidance are needed to guide decision making at end-operation.

Background: There is little guidance regarding empiric therapy for superficial surgical site infections (SSIs). Management of incisions with signs of SSI lacks consensus and management is variable among individual surgeons. Methods: The Surgical Infection Society was surveyed regarding management of SSIs. Cases were provided with varying wound descriptions, initial wound class (WC), post-operative day, and presence of a prosthesis. Responses were in multiple-choice format; statistics: χ2; α = 0.05. Results: Seventy-eight members responded. For appearance scenarios, respondents believed that both mild erythema (55%) and clear drainage (64%) could be observed, whereas substantial (>3 cm) erythema or purulence should be treated with complete (22% and 50%) or partial (55% and 40%) opening of the incision. Degree of erythema did not influence administration of antibiotic agents, but purulence was more likely than clear drainage to be treated with antibiotics (38% vs. 6%; p < 0.001). There were no differences based on WC, except that clean cases were more likely than higher WC scenarios to be treated with gram-positive coverage alone (WC 1 [26%] vs. 2 [10%] vs. 3 [13%] vs. 4 [4%]; p < 0.001). Post-operative day (POD) three appeared to be an inflection point for more aggressive treatment of suspected incisional SSI, with fewer (POD 0 [86%] vs. POD day 3 [54%]; p < 0.001) reporting observation. Respondents were more likely to obtain imaging, start broad-spectrum antibiotic agents, and return to the operating room for purulence in the presence of a mesh. Conclusions: Presented with escalating possibility of SSI, respondents reported lower rates of observation, increased use of antibiotic agents, and increased surgical drainage. Many scenarios lack consensus regarding appropriate therapy. The complete elimination of SSIs is unlikely to be accomplished soon, and this study provides a framework for understanding how surgeons approach SSIs, and potential areas for further research or pragmatic guidance.

BACKGROUND: High-quality CT can exclude hollow viscus injury (HVI) in patients with abdominal seatbelt sign (SBS) but performs poorly at identifying HVI. Delay in diagnosis of HVI has significant consequences necessitating timely identification. STUDY DESIGN: This multicenter, prospective observational study conducted at 9 trauma centers between August 2020 and October 2021 included adult trauma patients with abdominal SBS who underwent abdominal CT before surgery. HVI was determined intraoperatively and physiologic, examination, laboratory, and imaging findings were collected. Least absolute shrinkage and selection operator- and probit regression-selected predictor variables and coefficients were used to assign integer points for the HVI score. Validation was performed by comparing the area under receiver operating curves (AUROC). RESULTS: Analysis included 473 in the development set and 203 in the validation set. The HVI score includes initial systolic blood pressure <110 mmHg, abdominal tenderness, guarding, and select abdominal CT findings. The derivation set has an AUROC of 0.96, and the validation set has an AUROC of 0.91. The HVI score ranges from 0 to 17 with score 0 to 5 having an HVI risk of 0.03% to 5.36%, 6 to 9 having a risk of 10.65% to 44.1%, and 10 to 17 having a risk of 58.59% to 99.72%. CONCLUSIONS: This multicenter study developed and validated a novel HVI score incorporating readily available physiologic, examination, and CT findings to risk stratify patients with an abdominal SBS. The HVI score can be used to guide decisions regarding management of a patient with an abdominal SBS and suspected HVI.

ABSTRACT: Background: Smoking may offer pathophysiologic adaptations that increase survivability in certain patients with cardiovascular disease. We sought to identify if smoking increases survivability in trauma patients, hypothesizing that critically ill trauma patients who smoke have a decreased risk of mortality compared with non-smokers. Methods: The Trauma Quality Improvement Program (2010-2016) database was queried for trauma patients with intensive care unit admissions. A multivariable logistic regression model was performed. Results: From the 630,278 critically ill trauma patients identified, 116,068 (18.4%) were current cigarette smokers. Critically ill trauma smokers, compared with non-smokers, had a higher rate of pneumonia (7.8% vs. 6.9%, P< 0.001) and lower mortality rate (4.0% vs. 8.0%, P< 0.001). After controlling for covariates, smokers had a decreased associated risk of mortality compared with non-smokers (OR = 0.55, CI = 0.51-0.60, P< 0.001), and no difference in the risk of major complications (OR = 0.98, CI = 0.931.03, P = 0.44). The same analysis was performed using age as a continuous variable with associated decreased risk of mortality (OR 0.57 (CI 0.53-0.62), P< 0.001). Conclusion: Critically ill trauma smokers had a decreased associated mortality risk compared with non-smokers possibly due to biologic adaptations such as increased oxygen delivery developed from smoking. Future basic science and translational studies are needed to pursue potential novel therapeutic benefits without the deleterious long-term side effects of smoking.

Background: The principles of antimicrobial stewardship promote the appropriate prescribing of agents with respect to efficacy, safety, duration, and cost. Antibiotic resistance often results from inappropriate use (e.g., indication, selection, duration). We evaluated practice variability in duration of antimicrobials in surgical infection treatment (Rx) or prophylaxis (Px). Hypothesis: There is lack of consensus regarding the duration of antibiotic Px and Rx for many common indications. Methods: A survey was distributed to the Surgical Infection Society (SIS) regarding the use of antimicrobial agents for a variety of scenarios. Standard descriptive statistics were used to compare survey responses. Heterogeneity among question responses were compared using the Shannon Index, expressed as natural units (nats). Results: Sixty-three SIS members responded, most of whom (67%) have held a leadership position within the SIS or contributed as an annual meeting moderator or discussant; 76% have been in practice for more than five years. Regarding peri-operative Px, more than 80% agreed that a single dose is adequate for most indications, with the exceptions of gangrenous cholecystitis (40% single dose, 38% pre-operative +24 hours) and inguinal hernia repair requiring a bowel resection (70% single dose). There was more variability regarding the use of antibiotic Px for various bedside procedures with respondents split between none needed (range, 27%-66%) versus a single dose (range, 31%-67%). Opinions regarding the duration of antimicrobial Rx for hospitalized patients who have undergone a source control operation or procedure varied widely based on indication. Only two of 20 indications achieved more than 60% consensus despite available class 1 evidence: seven days for ventilator-associated pneumonia (77%), and four plus one days for perforated appendicitis (62%). Conclusions: Except for peri-operative antibiotic Px, there is little consensus regarding antibiotic duration among surgical infection experts, despite class 1 evidence and several available guidelines. This highlights the need for further high-level research and better dissemination of guidelines.
