RESUMEN
OBJECTIVES: To describe the technique and results of a new sagittal plane computed tomography (CT)-based angular measure for predicting stability after posterior wall acetabular fractures (PWF). DESIGN: Retrospective review. SETTING: Academic Level II trauma center. PATIENT SELECTION CRITERIA: Fifty-eight consecutive patients with PWF (AO/OTA class 62A.1), 98% were high-energy injuries. INTERVENTION: A new sagittal CT measure of PWF based on the angle subtending the joint center, cranial and caudal fracture exits. OUTCOME MEASURES AND COMPARISONS: Hip incongruity or dislocation demonstrated using gold standard test, examination under anesthesia (EUA), or instability on static images. Prediction of hip instability using a sagittal CT angular measure based on cranial and caudal fracture exits was compared with previous axial CT measures suggestive of increased risk for instability including posterior wall size >50%, and those with cranial exit within 5.0 mm of the acetabular dome. RESULTS: There were 32 operative and 26 nonoperatively treated fractures. Thirty fractures were determined to be unstable, and 28 were stable after EUA. Measurements of >70 degrees using the sagittal CT angular measure predicted instability in 28 of 28 patients, and ≤70 degrees predicted stability in 30 of 30 patients (sensitivity 100% and specificity 100%). Prevalence of EUA confirmed instability for subgroups with PWF based on prior axial CT measures were as follows: ≥50% wall involvement (11/16; sensitivity 67% and specificity 60%; 95% CI, 45%-89%/45%-75%), fracture within 5.0 mm of dome (5/18; sensitivity 86% and specificity 73%; 95% CI, 71%-100%/59%-87%), fracture within 5.0 mm of dome and ≥50% involvement (1/9; sensitivity 89% and specificity 56%; 95% CI, 69%-100%/24%-88%). CONCLUSIONS: In a sample of 58 mostly high energy posterior wall fractures all having had an EUA, a new sagittal angular CT measurement of ≤70 degrees predicted hip stability and >70 degrees predicted instability with 100% sensitivity and specificity. LEVEL OF EVIDENCE: Diagnostic Level III. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVE: This study aimed to determine whether lower extremity fracture fixation technique and timing (≤24 vs. >24 hours) impact neurologic outcomes in TBI patients. METHODS: A prospective observational study was conducted across 30 trauma centers. Inclusion criteria were age 18 years and older, head Abbreviated Injury Scale (AIS) score of >2, and a diaphyseal femur or tibia fracture requiring external fixation (Ex-Fix), intramedullary nailing (IMN), or open reduction and internal fixation (ORIF). The analysis was conducted using analysis of variamce, Kruskal-Wallis, and multivariable regression models. Neurologic outcomes were measured by discharge Ranchos Los Amigos Revised Scale (RLAS-R). RESULTS: Of the 520 patients enrolled, 358 underwent Ex-Fix, IMN, or ORIF as definitive management. Head AIS was similar among cohorts. The Ex-Fix group experienced more severe lower extremity injuries (AIS score, 4-5) compared with the IMN group (16% vs. 3%, p = 0.01) but not the ORIF group (16% vs. 6%, p = 0.1). Time to operative intervention varied between the cohorts with the longest time to intervention for the IMN group (median hours: Ex-Fix, 15 [8-24] vs. ORIF, 26 [12-85] vs. IMN, 31 [12-70]; p < 0.001). The discharge RLAS-R score distribution was similar across the groups. After adjusting for confounders, neither method nor timing of lower extremity fixation influenced the discharge RLAS-R. Instead, increasing age and head AIS score were associated with a lower discharge RLAS-R score (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.002-1.03 and OR, 2.37; 95% CI, 1.75-3.22), and a higher Glasgow Coma Scale motor score on admission (OR, 0.84; 95% CI, 0.73-0.97) was associated with higher RLAS-R score at discharge. CONCLUSION: Neurologic outcomes in TBI are impacted by severity of the head injury and not the fracture fixation technique or timing. Therefore, the strategy of definitive fixation of lower extremity fractures should be dictated by patient physiology and the anatomy of the injured extremity and not by the concern for worsening neurologic outcomes in TBI patients. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

BACKGROUND: Neighborhood location and its built environment are important social determinants of health that impact health outcomes. Older adults (OAs) represent the fastest growing population in the United States with many requiring emergency general surgery procedures (EGSPs). The aim of this study was to evaluate whether neighborhood location, represented by zip code, influences mortality and disposition in OAs undergoing EGSPs in Maryland. METHODS: A retrospective review was undertaken of hospital encounters in the Maryland Health Services Cost Review Commission from 2014 to 2018 of OAs undergoing EGSPs. Older adults residing in the 50 most affluent (MANs) and 50 least affluent (LANs) neighborhoods based on zip codes were compared. Data collected included demographics, all patient-refined (APR)-severity of illness (SOI), APR-risk of mortality (ROM), Charlson Comorbidity Index, complications, mortality, and discharge to a higher level of care. RESULTS: Of the 8661 OAs analyzed, 2362 (27.3%) resided in MANs and 6299 (72.7%) in LANs. Older adults in LANs were more likely to undergo EGSPs, had higher APR-SOI and APR-ROM, and experienced more complications, discharge to higher level of care, and mortality. Living in LANs was independently associated with discharge to higher level of care (OR 1.56, 95% CI: 1.38-1.77, P < .001) and increased mortality (OR 1.35, 95% CI: 1.07-1.71, P = .01). DISCUSSION: Mortality and quality of life in OAs undergoing EGSPs are dependent on environmental factors likely determined by neighborhood location. These factors need to be defined and incorporated in predictive models of outcomes. Public health opportunities to improve outcomes for those who are socially disadvantaged are necessary.

BACKGROUND: Surgical rescue (SR) is the recovery of patients with surgical complications. Patients transferred (TP) for surgical diagnoses to higher-level care or inpatients (IP) admitted to nonsurgical services may develop intra-abdominal infection (IAI) and require emergency surgery (ES). The aims were to characterize the SR population by the site of ES consultation, open abdomen (OA), and risk of mortality. STUDY DESIGN: This was an international, multi-institutional prospective observational study of patients requiring ES for IAI. Laparotomy before the transfer was an exclusion criterion. Patients were divided into groups: clinic/ED (C/ED), IP, or TP. Data collected included demographics, the severity of illness (SOI), procedures, OA, and number of laparotomies. The primary outcome was mortality. Multivariable logistic regression models were constructed. RESULTS: There were 752 study patients (C/ED 63.8% vs TP 23.4% and IP 12.8%), with a mean age of 59 years and 43.6% women. IP had worse SOI scores (Charlson Comorbidity Index, American Society of Anesthesiologists Physical Status Classification System, and Sequential Organ Failure Assessment). The most common procedures were small and large bowel (77.3%). IP and TP had similar rates of OA (IP 52.1% and TP 52.3 %) vs C/ED (37.7%, p < 0.001), and IP had more relaparotomies (3 or 4). The unadjusted mortality rate was highest in IP (n = 24, 25.0%) vs TP (n = 29, 16.5%) and C/ED (n = 68, 14.2%, p = 0.03). Adjusting for age and SOI, only SOI had an impact on the risk of mortality (area under the curve 86%). CONCLUSIONS: IP had the highest unadjusted mortality after ES for IAI and was followed by the TP; SOI drove the risk of mortality. SR must be extended to IP for timely recognition of the IAI.

PURPOSE: Previous studies have shown older adults receive relatively less protection from seat belts against fatal injuries, however it is unknown how seat belt protection against severe and torso injury changes with age. We estimated age-based variability in seat belt protection against fatal injuries, injuries with maximum abbreviated injury scale greater than two (MAIS 3+), and torso injuries. METHODS: We leveraged the Crash Outcome Data Evaluation System to analyze binary indicators of fatal, MAIS 3+, and torso injuries. Using a matched cohort design and conditional Poisson regression, we estimated age-based relative risks (RR) of the outcomes associated with seat belt use. RESULTS: Our results suggested that seat belts were highly protective against fatal injuries for all ages. For ages 16-30, seat belt use was associated with 66% lower risk of MAIS3+ injury (RR 0.34, 95% CI 0.30, 0.38) for occupants of the same vehicle, whereas for ages 75 and older, seat belt use was associated with 38% lower risk of MAIS3+ injury (RR 0.62; 95% CI 0.45, 0.86) for occupants in the same vehicle. The association between restraint use and torso injury also attenuated with age. CONCLUSIONS: In multi-occupant crashes, seat belts were highly protective against fatal and MAIS3+ injury, however seat belt protection against MAIS3+ and torso injury attenuated with age.

OBJECTIVE: Seat belt usage has increased substantially since the 1960s, yet driver use continues to affect passenger usage. Recent observational restraint use findings for Maryland will examine the relationship between driver and passenger usage, including adults and children in the rear seat. METHODS: Analyses were based on observational front and rear seat studies administered in parallel from 2016 to 2019. A statistically rigorous front seat project yielded weighted results among drivers and outboard passengers. A study of adults and children in the rear seat was based on a convenience sample of vehicles. Restraint usage results were presented as frequencies and proportions among occupants with known belt use, along with the 95% confidence interval for overall rates. RESULTS: Overall restraint usage rates averaged 90.9% in the front seat study and 81.1% in the rear seat sample. In vehicles with two front seat occupants and a belted driver, the proportion of belted passengers averaged 93.0% over four years. However, among unbelted drivers, only 41.6% of passengers were belted on average. In the rear seat study, an average of 82.7% were belted in vehicles driven by a restrained driver, differing for children (92.0%) versus adults (70.4%). Analysis of vehicles with an unbelted driver revealed an average of 45.0% of belted rear seat occupants, with a considerable difference for children (65.0%) compared with adults (21.0%). CONCLUSIONS: Observational seat belt studies in Maryland in recent years have shown that, despite overall rates above 80%, passenger use in both the front and rear seats is associated with driver restraint use.

BACKGROUND: Older adults (OAs; ≥ 65 years) comprise a growing population in the United States and are anticipated to require an increasing number of emergency general surgery procedures (EGSPs). The aims of this study were to identify the frequency of EGSPs and compare cost of care in OAs managed at teaching hospitals (THs) vs nonteaching hospitals (NTHs). METHODS: A retrospective review of data from the Maryland Health Services Cost Review Commission database from 2009 to 2018 for OAs undergoing EGSPs was undertaken. Data collected included demographics, all patient-refined (APR)-severity of illness (SOI), APR-risk of mortality (ROM), Charlson Comorbidity Index (CCI), EGSPs (partial colectomy (PC), small bowel resection, cholecystectomy, operative management of peptic ulcers, lysis of adhesions, appendectomy, and laparotomy, categorized hospital charges, length of stay (LOS), and mortality. RESULTS: Of the 55,401 OAs undergoing EGSPs in this study, 28,575 (51.6%) were treated at THs and 26,826 (48.4%) at NTHs. OAs at THs presented with greater APR-ROM (major 25.6% vs 24.9%, extreme 22.6% vs 22.0%, P=.01), and CCI (3.1±3 vs 2.7±2.8, P<.001) compared to NTHs. Lysis of adhesions, cholecystectomy, and PC comprised the overall most common EGSPs. Older adults at THs incurred comparatively higher median hospital charges for every EGSP due to increased room charges and LOS. Mortality was higher at THs (6.13% vs 5.33%, P<.001). CONCLUSION: While acuity of illness appears similar, cost of undergoing EGSPs for OAs is higher in THs vs NTHs due to increased LOS. Future work is warranted to determine and mitigate factors that increase LOS at THs.

BACKGROUND: The American Association for the Surgery of Trauma (AAST) has developed a grading system for emergency general surgery (EGS) conditions. We sought to validate the AAST EGS grades for patients undergoing urgent/emergent colorectal resection. METHODS: Patients enrolled in the "Eastern Association for the Surgery of Trauma Multicenter Colorectal Resection in EGS-to anastomose or not to anastomose" study undergoing urgent/emergent surgery for obstruction, ischemia, or diverticulitis were included. Baseline demographics, comorbidity severity as defined by Charlson comorbidity index (CCI), procedure type, and AAST grade were prospectively collected. Outcomes included length of stay (LOS) in-hospital mortality, and surgical complications (superficial/deep/organ-space surgical site infection, anastomotic leak, stoma complication, fascial dehiscence, and need for further intervention). Multivariable logistic regression models were used to describe outcomes and risk factors for surgical complication or mortality. RESULTS: There were 367 patients, with a mean (± SD) age of 62 ± 15 years. 39% were women. The median interquartile range (IQR) CCI was 4 (2-6). Overall, the pathologies encompassed the following AAST EGS grades: I (17, 5%), II (54, 15%), III (115, 31%), IV (95, 26%), and V (86, 23%). Management included laparoscopic (24, 7%), open (319, 87%), and laparoscopy converted to laparotomy (24, 6%). Higher AAST grade was associated with laparotomy (P = .01). The median LOS was 13 days (8-22). At least 1 surgical complication occurred in 33% of patients and the mortality rate was 14%. Development of at least 1 surgical complication, need for unplanned intervention, mortality, and increased LOS were associated with increasing AAST severity grade. On multivariable analysis, factors predictive of in-hospital mortality included AAST organ grade, CCI, and preoperative vasopressor use (odds ratio (OR) 1.9, 1.6, 3.1, respectively). The American Association for the Surgery of Trauma emergency general surgery grade was also associated with the development of at least 1 surgical complication (OR 2.5), while CCI, preoperative vasopressor use, respiratory failure, and pneumoperitoneum were not. CONCLUSION: The American Association for the Surgery of Trauma emergency general surgery grading systems display construct validity for mortality and surgical complications after urgent/emergent colorectal resection. These results support incorporation of AAST EGS grades for quality benchmarking and surgical outcomes research.

BACKGROUND: Stroke risk factors after blunt cerebrovascular injury (BCVI) are ill-defined. We hypothesized that factors associated with stroke for BCVI would include medical therapy (i.e., Aspirin), radiographic features, and protocolization of care. METHODS: An Eastern Association for the Surgery of Trauma-sponsored, 16-center, prospective, observational trial was undertaken. Stroke risk factors were analyzed individually for vertebral artery (VA) and internal carotid artery (ICA) BCVI. Blunt cerebrovascular injuries were graded on the standard 1 to 5 scale. Data were from the initial hospitalization only. RESULTS: Seven hundred seventy-seven BCVIs were included. Stroke rate was 8.9% for all BCVIs, with an 11.7% rate of stroke for ICA BCVI and a 6.7% rate for VA BCVI. Use of a management protocol (p = 0.01), management by the trauma service (p = 0.04), antiplatelet therapy over the hospital stay (p < 0.001), and Aspirin therapy specifically over the hospital stay (p < 0.001) were more common in ICA BCVI without stroke compared with those with stroke. Antiplatelet therapy over the hospital stay (p < 0.001) and Aspirin therapy over the hospital stay (p < 0.001) were more common in VA BCVI without stroke than with stroke. Percentage luminal stenosis was higher in both ICA BCVI (p = 0.002) and VA BCVI (p < 0.001) with stroke. Decrease in percentage luminal stenosis (p < 0.001), resolution of intraluminal thrombus (p = 0.003), and new intraluminal thrombus (p = 0.001) were more common in ICA BCVI with stroke than without, while resolution of intraluminal thrombus (p = 0.03) and new intraluminal thrombus (p = 0.01) were more common in VA BCVI with stroke than without. CONCLUSION: Protocol-driven management by the trauma service, antiplatelet therapy (specifically Aspirin), and lower percentage luminal stenosis were associated with lower stroke rates, while resolution and development of intraluminal thrombus were associated with higher stroke rates. Further research will be needed to incorporate these risk factors into lesion specific BCVI management. LEVEL OF EVIDENCE: Prognostic and Epidemiologic, Level IV.

BACKGROUND: Older adults (OAs) ≥ 65 years of age, representing the fastest growing segment in the United States, are anticipated to require a greater percentage of emergency general surgery procedures (EGSPs) with an associated increase in health care costs. The aims of this study were to identify the frequency of EGSP and charges incurred by OA compared to their younger counterparts in the state of Maryland. METHODS: A retrospective review of the Maryland Health Services Cost Review Commission from 2009 to 2018 was undertaken. Patients undergoing urgent or emergent ESGP were divided into 2 groups (18-64 years and ≥65 years). Data collected included demographics, APR-severity of illness (SOI), APR-risk of mortality (ROM), the EGSP (partial colectomy [PC], small bowel resection [SBR], cholecystectomy, operative management of peptic ulcer disease, lysis of adhesions, appendectomy, and laparotomy), length of stay (LOS), and hospital charges. P-values (P < .05) were significant. RESULTS: Of the 181,283 patients included in the study, 55,401 (38.1%) were ≥65 years of age. Older adults presented with greater APR-SOI (major 37.7% vs 21.3%, extreme 5.2% vs 9.3%), greater APR-ROM (major 25.3% vs 8.7%, extreme 22.3% vs 5.3%), underwent PC (24.5% vs 10.9%) and SBR (12.8% vs 7.0%) more frequently, and incurred significantly higher median hospital charges for every EGSP, consistently between 2009 and 2018 due to increased LOS and complications when compared to those ≤65 years of age. CONCLUSION: These findings stress the need for validated frailty indices and quality improvement initiatives focused on the care of OAs in emergency general surgery to maximize outcomes and optimize cost.

OBJECTIVE: Emergency general surgery (EGS) patients presenting with sepsis remain a challenge. The Surviving Sepsis Campaign recommends a 30 mL/kg fluid bolus in these patients, but recent studies suggest an association between large volume crystalloid resuscitation and increased mortality. The optimal amount of pre-operative fluid resuscitation prior to source control in patients with intra-abdominal sepsis is unknown. This study aims to determine if increasing volume of resuscitation prior to surgical source control is associated with worsening outcomes. METHODS: We conducted an 8-year retrospective chart review of EGS patients undergoing surgery for abdominal sepsis within 24 h of admission. Patients in hemorrhagic shock and those with outside hospital index surgeries were excluded. We grouped patients by increasing pre-operative resuscitation volume in 10 ml/kg intervals up to > 70 ml/kg and later grouped them into < 30 ml/kg or ≥ 30 ml/kg. A relative risk regression model compared amounts of fluid administration. Mortality was the primary outcome measure. Secondary outcomes were time to operation, ventilator days, and length of stay (LOS). Groups were compared by quick Sequential Organ Failure Assessment (qSOFA) and SOFA scoring systems. RESULTS: Of the 301 patients included, the mean age was 55, 51% were male, 257 (85%) survived to discharge. With increasing fluid per kg (< 10 to < 70 ml/kg), there was an increasing mortality per decile, 8.8% versus 31.6% (p = 0.004). Patients who received < 30 mL/kg had lower mortality (11.3 vs 21%) than those who received > 30 ml/kg (p = 0.02). These groups had median qSOFA scores (1.0 vs. 1.0, p = 0.06). There were no differences in time to operation (6.1 vs 4.9 h p = 0.11), ventilator days (1 vs 3, p = 0.08), or hospital LOS (8 vs 9 days, p = 0.57). Relative risk regression correcting for age and physiologic factors showed no significant differences in mortality between the fluid groups. CONCLUSIONS: Greater pre-operative resuscitation volumes were initially associated with significantly higher mortality, despite similar organ failure scores. However, fluid volumes were not associated with mortality following adjustment for other physiologic factors in a regression model. The amount of pre-operative volume resuscitation was not associated with differences in time to operation, ventilator days, ICU or hospital LOS.

BACKGROUND: Critical care ultrasound (CCUS) is essential in modern practice, with CCUS including cardiac and noncardiac ultrasound. The most effective CCUS training is unknown, with a diverse skill set and knowledge needed for competence. The objective of this project was to evaluate the effect of a surgical intensivist-led training program on CCUS competence in critical care fellows. METHODS: This was a single institution retrospective review from 2016 to 2018 at the R Adams Cowley Shock Trauma Center. Our yearlong surgical intensivist (SI)-led CCUS training program for critical care fellows includes a daylong CCUS training class, CCUS lectures, a CCUS rotation, and bedside CCUS instruction during rotations. Fellows take a knowledge test and skills test before (pretest) and after (posttest) this program. Critical care ultrasound skill was graded on a scale from 1-5, with 4 (minimal help) or 5 (no help) considered competent. Emergency medicine, surgery, and medicine-trained critical care fellows were included. RESULTS: Forty-two critical care fellows were included. Mean posttest scores increased significantly for 21/22 (96%) of skills tested and for 14/30 (47%) of knowledge questions compared to pretest scores. The mean composite skill score increased from 3.25 to 4.82 from pretest to posttest (P < .001). The mean composite knowledge score increased from 60% to 80% from pretest to posttest (P < .001). CONCLUSION: SI-led training improves CCUS competence and knowledge despite the breadth of CCUS.

OBJECTIVE: Evidence comparing stoma creation (STM) versus anastomosis after urgent or emergent colorectal resection is limited. This study examined outcomes after colorectal resection in emergency general surgery patients. METHODS: This was an Eastern Association for the Surgery of Trauma-sponsored prospective observational multicenter study of patients undergoing urgent/emergent colorectal resection. Twenty-one centers enrolled patients for 11 months. Preoperative, intraoperative, and postoperative variables were recorded. χ, Mann-Whitney U test, and multivariable logistic regression models were used to describe outcomes and risk factors for surgical complication/mortality. RESULTS: A total of 439 patients were enrolled (ANST, 184; STM, 255). The median (interquartile range) age was 62 (53-71) years, and the median Charlson Comorbidity Index (CCI) was 4 (1-6). The most common indication for surgery was diverticulitis (28%). Stoma group was older (64 vs. 58 years, p < 0.001), had a higher CCI, and were more likely to be immunosuppressed. Preoperatively, STM patients were more likely to be intubated (57 vs. 15, p < 0.001), on vasopressors (61 vs. 13, p < 0.001), have pneumoperitoneum (131 vs. 41, p < 0.001) or fecal contamination (114 vs. 33, p < 0.001), and had a higher incidence of elevated lactate (149 vs. 67, p < 0.001). Overall mortality was 13%, which was higher in STM patients (18% vs. 8%, p = 0.02). Surgical complications were more common in STM patients (35% vs. 25%, p = 0.02). On multivariable analysis, management with an open abdomen, intraoperative blood transfusion, and larger hospital size were associated with development of a surgical complication, while CCI, preoperative vasopressor use, steroid use, open abdomen, and intraoperative blood transfusion were independently associated with mortality. CONCLUSION: This study highlights a tendency to perform fecal diversion in patients who are acutely ill at presentation. There is a higher morbidity and mortality rate in STM patients. Independent predictors of mortality include CCI, preoperative vasopressor use, steroid use, open abdomen, and intraoperative blood transfusion. Following adjustment by clinical factors, method of colon management was not associated with surgical complications or mortality. LEVEL OF EVIDENCE: Therapeutic study, level IV.

BACKGROUND: Many states have legalized casino gambling, and casinos create increased vehicle traffic, but the strength of the association between casino construction and vehicle crashes is unknown. METHODS: Retrospective analyses of motor vehicle crashes (MVCs) occurring within Anne Arundel County, Maryland (2010-2014) were conducted. The ratio of crashes within one mile of the casino's location after it was opened were compared to the ratio occurring in the same area before it was opened to determine how the incidence of MVCs near the casino changed with time. Logistic regression was used to determine how crash characteristics may have influenced the incidence of MVCs near the casino after it opened. RESULTS: 101,860 persons were involved in 43,328 MVCs in Anne Arundel County during the study period; 29,476 (68.0 %) had an at-fault driver ≥21 years of age and complete data. MVCs proximal to the casino occurred most commonly during the day (N = 421, 76.6 %) and involved drivers <40 years of age (N = 366, 66.6 %) and male (N = 316, 57.4 %). After adjustment for impairment and day of the week, there was a significant association with crashes close to the casino after it opened (ORAdjusted = 1.23, 95 % CI: 1.04-1.46, p = 0.02). Crashes occurring close to the casino, after it opened, involved drivers <40 years of age (OR = 1.74, 95 % CI:1.45-2.08) and occurred on weekends (OR = 1.39, 95 %CI:1.15-1.67). CONCLUSIONS: In this single-site study the opening of a casino was associated with an increase in crashes nearby. The generalizability of this finding should be confirmed with analysis of MVC data near other gambling venues.

INTRODUCTION: Methylprednisolone has been used for acute respiratory distress syndrome with variable results. Veno-venous extracorporeal membrane oxygenation use in acute respiratory distress syndrome has increased. Occasionally, both are used. We hypothesized that methylprednisolone could improve lung compliance and ease weaning from extracorporeal membrane oxygenation in acute respiratory distress syndrome patients. METHODS: We retrospectively reviewed all patients in our veno-venous extracorporeal membrane oxygenation unit treated with methylprednisolone over a 20 month period. Methylprednisolone was initiated for inability to wean off veno-venous extracorporeal membrane oxygenation. Dynamic compliance (Cdyn) was calculated at cannulation, methylprednisolone initiation, and decannulation. Demographics, extracorporeal membrane oxygenation-specific data, and ventilator data were collected. Wilcoxon rank-sum test was used to test for differences in dynamic compliance. RESULTS: A total of 12 veno-venous extracorporeal membrane oxygenation patients received methylprednisolone. Mean age was 50 (±15) years. Seven had influenza. Methylprednisolone was started on median Day 16 (interquartile range: 11-22) of veno-venous extracorporeal membrane oxygenation. In total, 10 patients had veno-venous extracorporeal membrane oxygenation decannulation on median Day 12 (7-22) after methylprednisolone initiation. Two patients died before decannulation. The 10 decannulated patients had initial median dynamic compliance (mL × cm H2O-1) of 12 (7-23), then 16 (10-24) at methylprednisolone initiation, and then 44 (34-60) at decannulation. Dynamic compliance was higher at decannulation than methylprednisolone initiation (p = 0.002), and unchanged from cannulation to methylprednisolone initiation for all patients (p = 0.97). A total of 10 patients had significant infections. None had significant gastrointestinal bleed or wound healing issues. CONCLUSION: Methylprednisolone may be associated with improved compliance in acute respiratory distress syndrome allowing for decannulation from veno-venous extracorporeal membrane oxygenation. High rates of infection are associated with methylprednisolone use in veno-venous extracorporeal membrane oxygenation. Further studies are required to identify appropriate patient selection for methylprednisolone use in patients on veno-venous extracorporeal membrane oxygenation.

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.

In the past 30 years, opioid prescription rates have quadrupled and hospital admissions for overdose are rising. Previous studies have focused on alcohol use and trauma recidivism, however rarely evaluating recidivism and opioid use. We hypothesized there is an association between opioid use and trauma recidivism. This is a retrospective review of patients with multiple admissions for traumatic injury. Demographics, opioid toxicology screen (TS) results, and injury characteristics were collected. Statistical analysis was performed with chi-squared and Poisson regression models. One thousand six hundred forty-nine patients (age ≥18 years) had multiple trauma admissions. Seven hundred nine patients had TS data for both admissions. Thirty-one per cent (218) were TS positive on the 1st admission compared with 34 per cent (244) on their 2nd admission. Fifty-five per cent of patients who were TS positive on the 1st admission were positive on their 2nd admission, whereas 25 per cent who were TS negative on the 1st admission were subsequently positive on their 2nd admission (P < 0.0001). Patients who were TS positive on the subsequent admission were less severely injured than TS negative patients (Injury Severity Score > 15, 26.3% vs 22.3%, P = 0.04). The only significant risk factor for being TS positive on the 2nd admission was being TS positive on the 1st admission (relative risk = 2.18, P < 0.001). A previous history of opioid use is the strongest predictor of recurrent use in recidivists.

Present literature seems to support the nonoperative management of penetrating renal trauma although data remain limited. We conducted a nine-year retrospective review of nonoperative versus operative management and mechanism of injury [stab wound (SW) versus gunshot wound (GSW)] among patients admitted with penetrating renal trauma. Of 203 patients, the median age was 24 years, with the majority being male and having GSW injuries. More than half (52.2%) were treated nonoperatively (69.9% of SW and 40% of GSW injured patients). When compared with all operative patients combined, nonoperative patients had a lower median Injury Severity Score (17 vs 26, P < 0.001), lower transfusion requirement (27.4% vs 77.3%, P < 0.001), shorter median hospital stay (4.7 vs 12.6 days, P < 0.001), and lower mortality (1.9% vs 13.4%, P = 0.002). Gunshot wound patients had a higher median Injury Severity Score (26 vs 14, P < 0.001), higher median American Association for the Surgery of Trauma-Organ Injury Score (3 vs 2, P = 0.001), greater need for transfusion (69.2% vs 29.3%, P < 0.001), longer median hospital length of stay (12.1 vs 3.9 days, P < 0.001), and greater mortality (12.5% vs 0%, P < 0.001) than SW patients. Nonoperative management of penetrating renal injury is safe in selected patients. In addition, renal GSW injuries are associated with a greater morbidity and mortality.

BACKGROUND: Fatality rates following penetrating traumatic brain injury (pTBI) are extremely high and survivors are often left with significant disability. Infection following pTBI is associated with worse morbidity. The modern rates of central nervous system infections (INF) in civilian survivors are unknown. This study sought to determine the rate of and risk factors for INF following pTBI and to determine the impact of antibiotic prophylaxis. METHODS: Seventeen institutions submitted adult patients with pTBI and survival of more than 72 hours from 2006 to 2016. Patients were stratified by the presence or absence of infection and the use or omission of prophylactic antibiotics. Study was powered at 85% to detect a difference in infection rate of 5%. Primary endpoint was the impact of prophylactic antibiotics on INF. Mantel-Haenszel χ and Wilcoxon's rank-sum tests were used to compare categorical and nonparametric variables. Significance greater than p = 0.2 was included in a logistic regression adjusted for center. RESULTS: Seven hundred sixty-three patients with pTBI were identified over 11 years. 7% (n = 51) of patients developed an INF. Sixty-six percent of INF patients received prophylactic antibiotics. Sixty-two percent of all patients received one dose or greater of prophylactic antibiotics and 50% of patients received extended antibiotics. Degree of dural penetration did not appear to impact the incidence of INF (p = 0.8) nor did trajectory through the oropharynx (p = 0.18). Controlling for other variables, there was no statistically significant difference in INF with the use of prophylactic antibiotics (p = 0.5). Infection was higher in patients with intracerebral pressure monitors (4% vs. 12%; p = <0.001) and in patients with surgical intervention (10% vs. 3%; p < 0.001). CONCLUSION: There is no reduction in INF with prophylactic antibiotics in pTBI. Surgical intervention and invasive intracerebral pressure monitoring appear to be risk factors for INF regardless of prophylactic use. LEVEL OF EVIDENCE: Therapeutic, level IV.

BACKGROUND: Clinical frailty scores usually involve questionnaires or physical testing. Many trauma patients are not able to participate in these. Radiographic measurement of frailty may be a viable alternative. Individual radiographic markers of frailty have been investigated, such as sarcopenia or osteopenia. The ideal radiographic variable (or variables) to measure frailty in trauma is unknown. STUDY DESIGN: A retrospective review was performed of restrained drivers ages 40 and greater at a single institution from 2010-2015. Multiple markers of radiographic frailty were measured including: sarcopenia, osteopenia, vascular calcifications, sarcopenic obesity, emphysema, renal volume, cervical spine degeneration, and cerebral atrophy. Frailty was defined as the worst quartile for each radiographic variable, and these values were summed to create a composite marker of frailty. The primary outcome was discharge disposition. We hypothesized that a composite frailty score would be associated with discharge disposition while individual markers would not be associated with discharge disposition. RESULTS: Overall 489 patients were included in this study. Cerebral atrophy (p = 0.05), renal volume (p = 0.004), sarcopenia (p = 0.05), vascular calcifications (p = 0.02) and sarcopenic obesity (p = 0.01) were associated with discharge disposition. Pearson's correlation coefficients between radiographic frailty markers were all less than 0.4. Youden's Index was 0.26 (p < 0.001) at a composite score of 3. In multivariable analysis, the composite score of 3 or greater was associated with poor discharge disposition (OR 2.39, 95% CI 1.10-5.18, p = 0.03). CONCLUSIONS: Individual radiographic frailty markers are inadequate markers of frailty, as they may miss patients who are frail. This study also suggests that a composite radiographic frailty score may better predict patient outcome than individual radiographic markers of frailty.
