Differences in Characteristics and Outcome of Patients with Penetrating Injuries in the USA and the Netherlands: A Multi-institutional Comparison
Introduction: The incidence and nature of penetrating injuries differ between countries. The aim of this study was to analyze characteristics and clinical outcomes of patients with penetrating injuries treated at urban Level-1 trauma centers in the USA (USTC) and the Netherlands (NLTC). Methods: In this retrospective cohort study, 1331 adult patients (470 from five NLTC and 861 from three USTC) with truncal penetrating injuries admitted between July 2011 and December 2014 were included. In-hospital mortality was the primary outcome. Outcome comparisons were adjusted for differences in population characteristics in multivariable analyses. Results: In USTC, gunshot wound injuries (36.1 vs. 17.4%, p < 0.001) and assaults were more frequent (91.2 vs. 77.7%, p < 0.001). ISS was higher in USTC, but the Revised Trauma Score (RTS) was comparable. In-hospital mortality was similar (5.0 vs. 3.6% in NLTC, p = 0.25). The adjusted odds ratio for mortality in USTC compared to NLTC was 0.95 (95% confidence interval 0.35–2.54). Hospital stay length of stay was shorter in USTC (difference 0.17 days, 95% CI −0.29 to −0.05, p = 0.005), ICU admission rate was comparable (OR 0.96, 95% CI 0.71–1.31, p = 0.80), and ICU length of stay was longer in USTC (difference of 0.39 days, 95% CI 0.18–0.60, p < 0.0001). More USTC patients were discharged to home (86.9 vs. 80.6%, p < 0.001). Readmission rates were similar (5.6 vs. 3.8%, p = 0.17). Conclusion: Despite the higher incidence of penetrating trauma, particularly firearm-related injuries, and higher hospital volumes in the USTC compared to the NLTC, the in-hospital mortality was similar. In this study, outcome of care was not significantly influenced by differences in incidence of firearm-related injuries
Treating acute colonic diverticulitis with extraluminal pericolic air: An Acute Care Surgery in the Netherlands (ACCSENT) multicenter retrospective cohort study
Background: Owing to improved quality of computed tomography, a new category of complicated acute diverticulitis, including patients with pericolic air but without abscess formation, can be defined (Hinchey 1a). Recent studies question whether this new category of acute diverticulitis could be treated as uncomplicated cases. The aim of our study is to report on the clinical course of acute diverticulitis Hinchey 1a in current clinical practice. Methods: For this multicenter retrospective cohort study, patients presenting at the emergency department with Hinchey 1a acute diverticulitis as demonstrated by computed tomography scan, were identified. The primary outcome measure was successful conservative treatment with observation alone, antibiotics, and/or hospital admission. Readmissions, percutaneous drainage of abscesses, and emergency operations were considered as failure. Results: Between October 2016 and October 2018, 1,199 patients were clinically suspected for acute diverticulitis, of whom 101 (8.4%) were radiologically diagnosed to have type 1a acute diverticulitis (average age 57 (±13) years, 45% female) and started with conservative treatment. This was successful in 86 (85%) patients. One of the 15 unsuccessfully treated patients (1%) received percutaneous drainage of an abdominal abscess. Surgery was required in 9 cases (9%) after a median time of 6 days (range, 3 to 69 days). Although a difference in the volume of extraluminal air on computed tomography scan was found, this was not shown to be a risk factor for the clinical course. Conclusion: Patients with type 1a acute diverticulitis can be treated successfully by conservative therapy in the majority of cases (85%). More research is required to define predictive factors for successful conservative management
Goal-directed diuresis: A case - control study of continuous furosemide infusion in critically ill trauma patients
Background: Excessive crystalloid administration is common and associated with negative outcomes in critically ill trauma patients. Continuous furosemide infusion (CFI) to remove excessive fluid has not been previously described in this population. We hypothesized that a goal-directed CFI is more effective for fluid removal than intermittent bolus injection (IBI) diuresis without excess incidence of hypokalemia or renal failure. Materials and Methods: CFI cases were prospectively enrolled between November 2011 and August 2012, and matched to historic IBI controls by age, gender, Injury Severity Score (ISS), and net fluid balance (NFB) at diuresis initiation. Paired and unpaired analyses were performed to compare groups. The primary endpoints were net fluid balance, potassium and creatinine levels. Secondary endpoints included intensive care unit (ICU) and hospital length of stay (LOS), ventilator-free days (VFD), and mortality. Results: 55 patients were included, with 19 cases and 36 matched controls. Mean age was 54 years, mean ISS was 32.7, and mean initial NFB was +7.7 L. After one day of diuresis with CFI vs. IBI, net 24 h fluid balance was negative (−0.55 L vs. +0.43 L, P = 0.026) only for the CFI group, and there was no difference in potassium and creatinine levels. Cumulative furosemide dose (59.4mg vs. 25.4mg, P < 0.001) and urine output (4.2 L vs. 2.8 L, P < 0.001) were also significantly increased with CFI vs. IBI. There were no statistically significant differences in ICU LOS, hospital LOS, VFD, or mortality. Conclusions: Compared to IBI, goal-directed diuresis by CFI is more successful in achieving net negative fluid balance in patients with fluid overload with no detrimental side effects on renal function or patient outcome
Effects of a New Hospital-Wide Surgical Consultation Protocol in Patients with Clostridium difficile Colitis
Background:
Fulminant
Clostridium difficile
colitis (fCDC) occurs in 2%–8% of patients with CDC and carries a high death rate. Prompt operation may reduce death. Our aim was to determine whether a standardized hospital-wide protocol for surgical referral in CDC would result in earlier surgical consultation, earlier identification of patients who could benefit from surgical therapy, and reduced deaths from fCDC.
Methods:
A multidisciplinary team developed consensus criteria for surgical consultation. Compliance was evaluated by prospective review of all inpatient CDC cases. Outcomes of the prospective cohort (POST) were compared to an historic control group (PRE).
Results:
From November 1, 2010 to October 31, 2012, we identified 1,106 inpatients with CDC; 339 patients matched the consultation criteria, of whom 213 received a surgical consultation, resulting in an overall compliance rate of 62.8%. All those with fCDC received a surgical consultation, with a median time to surgical referral of three hours. Of 46 patients with fCDC, 11 (23.9%) died, compared with 34.8% in the historical control group (p = 0.15). The death rate was 14.7% in the POST group, when excluding patients with limitations of care and those transferred to our institution in a fulminant state. There was a shorter interval between admission and surgical intervention for those who required operation in the POST group—three (1–11) days versus 1.5 (0–3) days, respectively, in the PRE and POST groups (p = 0.018), and a shorter adjusted median hospital length of stay (adjusted difference 9.0, 95% CI 2.2–12.3, p = 0.007)
Conclusions:
A hospital-wide protocol with established criteria for surgical consultation resulted in faster intervention and a shorter adjusted median hospital length of stay. The overall death rate for fCDC patients without limitations of life-sustaining treatment who presented to our emergency department or in whom fCDC developed while they were admitted to our hospital was 14.7%
Real-time heart rate entropy predicts the need for lifesaving interventions in trauma activation patients
Heart rate complexity (HRC), commonly described as a "new vital sign," has shown promise in predicting injury severity, but its use in clinical practice has been precluded by the absence of real-time data. This study was conducted to evaluate the utility of real-time, automated, instantaneous, hand-held heart rate entropy analysis in predicting the need for lifesaving interventions (LSIs). We hypothesized that real-time HRC would predict LSIs.
Prospective enrollment of patients who met criteria for trauma team activation was conducted at a Level I trauma center (September 2011 to February 2012). A novel, hand-held, portable device was used to measure HRC (by sample entropy) and time-domain heart rate variability continuously in real time for 2 hours after the moment of presentation. Electric impedance cardiography was used to determine cardiac output. Patients who received an LSI were compared with patients without any intervention (non-LSI). Multivariable analysis was performed to control for differences between the groups.
Of 82 patients enrolled, 21 (26%) received 67 LSIs within 24 hours of hospital arrival. Initial systolic blood pressure was similar in both groups. LSI patients had a lower Glasgow Coma Scale (GCS) score (9.2 [5.1] vs. 14.9 [0.2], p < 0.0001). The mean (SD) HRC value on presentation was 0.8 (0.6) in the LSI group compared with 1.5 (0.6) in the non-LSI group (p < 0.0001). With the use of logistic regression, initial HRC was the only significant predictor of LSI. A cutoff value for HRC of 1.1 yields sensitivity, specificity, negative predictive value, and positive predictive value of 86%, 74%, 94%, and 53%, respectively, with an accuracy of 77% for predicting an LSI.
Decreased HRC on hospital arrival is an independent predictor of the need for LSI in trauma activation patients. Real-time HRC may be a useful adjunct to standard vital signs monitoring and predicts LSIs.

Antibiotic Regimen after a Total Abdominal Colectomy with Ileostomy for Fulminant Clostridium difficile
Interrupted versus continuous fascial closure in patients undergoing emergent laparotomy: A randomized controlled trial
BACKGROUNDThe optimal method of fascial closure, interrupted fascial closure (IFC) versus continuous fascial closure (CFC) has never been studied exclusively in the setting of emergency surgery. We hypothesized that IFC decreases postoperative incisional hernia development following emergent laparotomies.METHODSBetween August 2008 and September 2015, patients undergoing emergent laparotomies were consented and randomly assigned to either IFC or CFC. Patients were followed up postoperatively for at least 3 months and assessed for incisional hernia, dehiscence, or wound infection. We excluded those with trauma, elective surgery, mesh in place, primary ventral hernia, previous abdominal surgery within 30 days, or those not expected to survive for more than 48 hours. Our primary endpoint was the incidence of postoperative incisional hernias.RESULTSOne hundred thirty-six patients were randomly assigned to IFC (n = 67) or CFC (n = 69). Baseline characteristics were similar between the groups. No difference was noted in the length of the abdominal incision, or the peak inspiratory pressure after the closure. The median time needed for closure was significantly longer in the IFC group (22 minutes vs. 13 minutes, p < 0.001). Thirty-seven (55.2%) IFC and 41 (59.4%) CFC patients completed their follow-up visits. There was no statistically significant difference in baseline and intraoperative characteristics between those who completed follow-ups and those who did not. The median time from the day of surgery to the day of the last follow-up was similar between IFC and CFC (233 days vs. 216 days, p = 0.67), as were the rates of incisional hernia (13.5% versus 22.0%, p = 0.25), dehiscence (2.7% vs. 2.4%, p = 1.0), and surgical site infection (16.2% vs. 12.2%, p = 0.75).CONCLUSIONThere was no statistically detectable difference in postoperative hernia development between those undergoing IFC versus CFC after emergent laparotomies. However, this may be due to the relatively low sample size.LEVEL OF EVIDENCETherapeutic/Care Management Study, level III
