RESUMO
BACKGROUND: Despite the frequent occurrence of interhospital transfers in emergency general surgery (EGS), rates of transfer of complications are undescribed. Improved understanding of hospital transfer patterns has a multitude of implications, including quality measurement. The objective of this study was to describe individual hospital transfer rates of mortal encounters. MATERIALS AND METHODS: A retrospective review was undertaken from 2013 to 2015 of the Maryland Health Services Cost Review Commission database. Two groups of EGS encounters were identified: encounters with death following transfer and encounters with death without transfer. The percentage of mortal encounters transferred was defined as the percentage of EGS hospital encounters with mortality initially presenting to a hospital transferred to another hospital before death at the receiving hospital. RESULTS: Overall, 370,242 total EGS encounters were included, with 17,003 (4.6%) of the total EGS encounters with mortality. Encounters with death without transfer encompassed 15,604 (91.8%) of mortal EGS encounters and encounters with death following transfer 1399 (8.2%). EGS disease categories of esophageal varices or perforation, necrotizing fasciitis, enterocutaneous fistula, and pancreatitis had over 10% of these total mortal encounters with death following transfer. For individual hospitals, percentage of mortal encounters transferred ranged from 0.8% to 35.2%. The percentage of mortal encounters transferred was inversely correlated with annual EGS hospital volume for all state hospitals (P < 0.001, r = -0.57). CONCLUSIONS: Broad variability in individual hospital practices exists for mortality transferred to other institutions. Application of this knowledge of percentage of mortal encounters transferred includes consideration in hospital quality metrics.

INTRODUCTION: The use of veno-venous extracorporeal membrane oxygenation (VV ECMO) has increased over the past decade. The purpose of this study was to evaluate outcomes in adult trauma patients requiring VV ECMO. METHODS: Data were collected on adult trauma patients admitted between January 1, 2015, and November 1, 2016. Demographics, injury-specific data, ECMO data, and survival to discharge were recorded. Medians [interquartile range (IQR)] were reported. A p value ≤0.05 was considered statistically significant. RESULTS: Eighteen patients required VV ECMO during the study period. Median age was 28.5 years (IQR 24-43). Median injury severity score (ISS) was 27 (IQR 21-41); median PaO2/FiO2 (P/F) prior to ECMO cannulation was 61 (IQR 50-70). Median time from injury to cannulation was 3 (IQR 0-6) days. Median duration of ECMO was 266 (IQR 177-379) hours. Survival to discharge was 78%. Survivors had a significantly higher ISS (p = 0.03), longer intensive care unit length of stay (ICU LOS) (p < 0.0004), hospital LOS (p < 0.000004), and time on the ventilator (p < 0.0003). Median time of injury to cannulation was significantly longer in patients who survived to discharge (p = 0.01). There was no difference in P/F ratio prior to cannulation (p = ns). CONCLUSION: We have demonstrated improved outcome of patients requiring VV ECMO following injury compared to historical data. Although shorter time from injury to cannulation for VV ECMO was associated with death, select patients who meet criteria for VV ECMO early following injury should be referred/transferred to a tertiary care facility that specializes in trauma and ECMO care.

The purpose of this study was to evaluate survival to hospital discharge for patients on venovenous extracorporeal membrane oxygenation (VV ECMO) when stratified by age. We performed a retrospective study at single, academic, tertiary care center intensive care unit for VV ECMO. All patients, older than 17 years of age, on VV ECMO admitted to a specialized intensive care unit for the management of VV ECMO between August 2014 and May 2018 were included in the study. Trauma and bridge-to-lung transplant patients were excluded for this analysis. Demographics, pre-ECMO and ECMO data were collected. Primary outcome was survival to hospital discharge when stratified by age. Secondary outcomes included time on VV ECMO and hospital length of stay (HLOS). One hundred eighty-two patients were included. Median P/F ratio at time of cannulation was 69 [56-85], and respiratory ECMO survival prediction (RESP) score was 3 [1-5]. Median time on ECMO was 319 [180-567] hours. Overall survival to hospital discharge was 75.8%. Lowess and cubic spline curves demonstrated an inflection point associated with increased mortality at age >45 years. Kaplan-Meier analysis demonstrated significantly greater survival in patients <45 years of age (p = 0.0001). Survival to hospital discharge for those Assuntos

RESUMO
Hospitalizations for peptic ulcer disease (PUD) have decreased since the advent of specific medical therapy in the 1980s. The authors' clinical experience at a tertiary center, however, has been that procedures to treat PUD complications have not declined. This study tested the hypothesis that despite decreases in PUD hospitalizations, the volume of procedures for PUD complications has remained consistent. The study population included all inpatient encounters in the state of Maryland from 2009 to 2014 with a primary ICD-9 diagnosis code for PUD. Data on annual patient volume, demographics, anatomic location, procedures, complications, and outcomes were collected, and PUD prevalence rates were calculated. The study population consisted of the state's entire population, not a sample; statistical analysis was not applied. Hospitalizations for PUD declined from 2,502 in 2009 to 2,101 in 2014, whereas the percentage of hospitalizations with procedures increased from 27.1 to 31.5 per cent. Endoscopy was performed in 19.8 per cent of hospitalizations, operation in 9.4 per cent, and angiography in 1.3 per cent. Of 13,974 inpatient encounters, 30 per cent had at least one inhospital complication. Overall inpatient mortality was 2.2 per cent. PUD hospitalizations are declining in Maryland, mirroring national trends. A subset of patients continue to need urgent procedures for PUD complications, including nearly 10 per cent needing operation. Inpatient mortality among patients admitted for PUD was 2.2 per cent, congruent with other studies. Despite the efficacy of modern medical therapy, these data underscore the importance of teaching surgical residents the cognitive and operative skills necessary to manage PUD complications.

Interhospital transfer of emergency general surgery (EGS) patients is a common occurrence. Modern individual hospital practices for interhospital transfers have unknown variability. A retrospective review of the Maryland Health Services Cost Review Commission database was undertaken from 2013 to 2015. EGS encounters were divided into three groups: encounters not transferred, encounters transferred from a hospital, and encounters transferred to a hospital. In total, 380,405 EGS encounters were identified, including 12,153 (3.2%) encounters transferred to a hospital, 10,163 (2.7%) encounters transferred from a hospital, and 358,089 (94.1%) encounters not transferred. For individual hospitals, percentage of encounters transferred to a hospital ranged from 0 to 30.05 per cent, encounters transferred from a hospital from 0.02 to 14.62 per cent, and encounters not transferred from 69.25 to 99.95 per cent of total encounters at individual hospitals. Percentage of encounters transferred from individual hospitals was inversely correlated with annual EGS hospital volume (P < 0.001, r = -0.59), whereas percentage of encounters transferred to individual hospitals was directly correlated with annual EGS hospital volume (P < 0.001, r = 0.51). Individual hospital practices for interhospital transfer of EGS patients have substantial variability. This is the first study to describe individual hospital interhospital transfer practices for EGS.

The use of veno-venous extracorporeal membrane oxygenation (VV ECMO) in adults with respiratory failure has steadily increased during the past decade. Recent literature has demonstrated variable outcomes with the use of extended ECMO. The purpose of this study is to evaluate survival to hospital discharge in patients with extended ECMO runs compared with patients with short ECMO runs at a tertiary care ECMO referral center. We retrospectively reviewed all patients on VV ECMO for respiratory failure between August 2014 and February 2017. Bridge to lung transplant, post-lung transplant, and post-cardiac surgery patients were excluded. Patients were stratified by duration of ECMO: extended ECMO, defined as >504 hours; short ECMO as ≤504 hours. Demographics, pre-ECMO data, ECMO-specific data, and outcomes were analyzed. One hundred and thirty-nine patients with respiratory failure were treated with VV ECMO. Overall survival to discharge was 76%. Thirty-one (22%) patients had extended ECMO runs with an 87% survival to discharge. When compared with patients with short ECMO runs, there was no difference in median age, body mass index (BMI), body surface area (BSA), partial pressure of oxygen (PaO2)/ fraction of inspired oxygen (FiO2) (P/F), and survival to discharge. However, time from intubation to cannulation for ECMO was significantly longer in patients with extended ECMO runs. (p = 0.008). Our data demonstrate that patients with extended ECMO runs have equivalent outcomes to those with short ECMO runs. Although the decision to continue ECMO support in this patient population is multifactorial, we suggest that time on ECMO should not be the sole factor in this challenging decision.

Necrotizing soft tissue infection of the perineum, or Fournier's gangrene (FG), is a morbid and mortal diagnosis. Despite the severity of FG, the optimal definitive wound closure strategy is unknown, as are long-term wound outcomes. A retrospective review was performed over a 3-year period at a single trauma center. Patients were managed according to our institutional approach focusing on primary wound closure and secondary intention healing in residual wounds. Overall 168 patients were included. Complete primary wound closure was accomplished in 39.9 per cent of patients. Patients undergoing primary wound closure were primarily male (89.6 vs 64.4%, P < 0.001), had lower mean sequential organ failure assessment (SOFA) scores (1.70 ± 2.30 vs 2.98 ± 3.36, P = 0.004), more often had perineum-limited FG (67.2 vs 42.6%, P = 0.003), and required fewer debridements (2.40 vs 2.79, P = 0.02). On logistic regression, predictors of primary closure included gender (odds ratio 4.643, 95% confidence interval 1.885-11.437, P = 0.001) and SOFA score (odds ratio 0.834, 95% confidence interval 0.727-0.957, P = 0.01). Wound healing rates increased over time, to an 82.1 per cent wound healing rate without further intervention at greater than six months of follow-up. Wounds healed with secondary intention ranged from 70 to 9520 cm3 and primary closure ranged from 126 to 6912 cm3, whereas wounds requiring skin grafts ranged from 405 to 16,170 cm3. Complete primary wound closure is often achievable in FG patients. Using this standardized approach to FG wound management, even large wounds and wounds undergoing secondary intention healing will often close with long-term wound care and do not require flap creation or early skin grafting.

INTRODUCTION: The formation of Acute Care Surgery services leads to decreased time to treatment and improved outcomes for emergency general surgery (EGS) patients. However, minimal work has focused on the ideal care delivery system and team structure. We hypothesize that the implementation of a dedicated EGS team (separate from trauma and surgical critical care), with EGS-specific protocols and dedicated operating room (OR) time, will increase productivity and improve mortality. METHODS: This is a retrospective review of financial and EGS registry data from fiscal year (FY) 12 to FY15. Data are from an academic, university-based EGS team composed of two acute care surgery attending surgeons, advanced practitioners (APs), residents, and a fellow. In FY12, processes were implemented to standardize paging of consults, patient sign-out with attending surgeons' and APs' participation, clinical/billing protocols, OR availability, and quality improvement. Outcomes included relative value units (RVUs), surgical case volume, charges/payments, and number of patient encounters. The secondary outcome was mortality. The χ test was used to compare mortality, and p < 0.05 was considered significant. RESULTS: Total patient encounters increased from 6,723 in FY 12 to 9,238 in FY 15 (+37%). Relative value units increased from 18,422 in FY 12 to 25,314 in FY 15 (+37%). Charges increased by 76% and payments increased by 60% from FY 12 to FY 15. Charges per encounter increased from $461 in FY 12 to $591 in FY 15 (+28%) Additionally, both inpatient and surgical case loads increased. Mortality remained stable throughout the study period (FY 12, 4.5%; FY 13, 5.2%; FY 14, 5.3%; FY 15, 3.2%: p = 0.177). CONCLUSIONS: Implementation of dedicated OR time, defined EGS team structure, practice protocols, and active attending surgeons'/APs' participation was temporally related to increased case volume, patients seen, and revenue, while mortality remained unchanged. Further study is necessary to establish the translatability of these data to other systems. LEVEL OF EVIDENCE: Economic/decision, level III.

INTRODUCTION: Acute mesenteric ischemia is a surgical emergency that entails complex, multi-modal management, but its epidemiology and outcomes remain poorly defined. The aim of this study was to perform a population analysis of the contemporary incidence and outcomes of mesenteric ischemia. METHODS: This was a retrospective analysis of acute mesenteric ischemia in the state of Maryland during 2009-2013 using a comprehensive statewide hospital admission database. Demographics, illness severity, comorbidities, and outcomes were studied. The primary outcome was inpatient mortality. Survivors and non-survivors were compared using univariate analyses, and multivariable logistic regression analysis was performed to evaluate risk factors for mortality. RESULTS: During the 5-year study period, there were 3,157,499 adult hospital admissions in Maryland. A total of 2,255 patients (0.07%) had acute mesenteric ischemia, yielding an annual admission rate of 10/100,000. Increasing age, hypercoagulability, cardiac dysrhythmia, renal insufficiency, increasing illness severity, and tertiary hospital admission were associated with development of mesenteric ischemia. Inpatient mortality was high (24%). After multivariate analysis, independent risk factors for death were age >65 years, critical illness severity, mechanical ventilation, tertiary hospital admission, hypercoagulability, renal insufficiency, and dysrhythmia. CONCLUSION: Acute mesenteric ischemia occurs in approximately 1/1,000 admissions in Maryland. Patients with mesenteric ischemia have significant illness severity, substantial rates of organ dysfunction, and high mortality. Patients with chronic comorbidities and acute organ dysfunction are at increased risk of death, and recognition of these risk factors may enable prevention or earlier control of mesenteric ischemia in high-risk patients.
RESUMO
BACKGROUND: The short-term natural history of blunt cerebrovascular injuries (BCVIs) has been previously described in the literature, but the purpose of this study was to analyze long-term serial follow-up and lesion progression of BCVI. METHODS: This is a single institution's retrospective review of a prospectively collected database over four years (2009-2013). All patients with a diagnosis of BCVI by computed tomographic (CT) scan were identified, and injuries were graded based on modified Denver scale. Management followed institutional algorithm: initial whole-body contrast-enhanced CT scan, followed by CT angiography at 24 to 72 hours, 5 to 7 days, 4 to 6 weeks, and 3 months after injury. All follow-up imaging, medication management, and clinical outcomes through 6 months following injury were recorded. RESULTS: There were 379 patients with 509 injuries identified. Three hundred eighty-one injuries were diagnosed as BCVI on first CT (Grade 1 injuries, 126; Grade 2 injuries, 116; Grade 3 injuries, 69; and Grade 4 injuries, 70); 100 "indeterminate" on whole-body CT; 28 injuries were found in patients reimaged only for lesions detected in other vessels. Sixty percent were male, mean (SD) age was 46.5 (19.9) years, 65% were white, and 62% were victims of a motor vehicle crash. Most frequently, Grade 1 injuries were resolved at all subsequent time points. Up to 30% of Grade 2 injuries worsened, but nearly 50% improved or resolved. Forty-six percent of injuries originally not detected were subsequently diagnosed as Grade 3 injuries. Greater than 70% of all imaged Grade 3 and Grade 4 injuries remained unchanged at all subsequent time points. CONCLUSIONS: This study revealed that there are many changes in grade throughout the six-month time period, especially the lesions that start out undetectable or indeterminate, which become various grade injuries. Low-grade injuries (Grades 1 and 2) are likely to remain stable and eventually resolve. Higher-grade injuries (Grades 3 and 4) persist, many up to six months. Inpatient treatment with antiplatelet or anticoagulation did not affect BCVI progression. LEVEL OF EVIDENCE: Prognostic study, level III; therapeutic study, level IV.

INTRODUCTION: Our whole-body computed tomography protocol (WBCT), used to image patients with polytrauma, consists of a noncontrast head computed tomography (CT) followed by a multidetector computed tomography (40- or 64- slice) that includes an intravenous, contrast-enhanced scan from the face through the pelvis. WBCT is used to screen for blunt cerebrovascular injury (BCVI) during initial CT imaging of the patient with polytrauma and allows for early initiation of therapy with the goal of avoiding stroke. WBCT has not been directly compared with CT angiography (CTA) of the neck as a screening tool for BCVI. We hypothesize that WBCT is a valid modality to diagnose BCVI compared with neck CTA, thus screening patients with polytrauma for BCVI and limiting the need for subsequent CTA. METHODS: A retrospective review of the trauma registry was conducted for all patients diagnosed with BCVI from June 2009 to June 2013 at our institution. All injuries, identified and graded on initial WBCT, were compared with neck CTA imaging performed within the first 72 hours. Sensitivity was calculated for WBCT by the use of CTA as the reference standard. Proportions of agreement also were calculated between the grades of injury for both imaging modalities. RESULTS: A total of 319 injured vessels were identified in 227 patients. On initial WBCT 80 (25%) of the injuries were grade I, 75 (24%) grade II, 45 (14%) grade III, 41 (13%) grade IV, and 58 (18%) were classified as indeterminate: 27 vertebral and 31 carotid lesions. Twenty (6%) of the 319 injuries were not detected on WBCT but identified on subsequent CTA (9 grade I, 7 grade II, 4 grade III); 6 vertebral and 14 carotid. For each vessel type and for all vessels combined, WBCT demonstrated sensitivity rates of over 90% to detect BCVI among the population of patients with at least one vessel injured. There was concordant grading of injuries between WBCT and initial diagnostic CTA in 154 (48% of all injuries). Lower grade injures were more discordant than higher grades (55% vs 13%, respectively; P < .001). Grading was upgraded 8% of the time and downgraded 25%. CONCLUSION: WBCT holds promise as a rapid screening test for BCVI in the patient with polytrauma to identify injuries in the early stage of the trauma evaluation, thus allowing more rapid initiation of treatment. In addition, in those patients with high risk for BCVI but whose WBCT results are negative for BCVI, neck CTA should be considered to more confidently exclude low-grade injuries.
