Observational Study
Emergency Department Central Line-associated Bloodstream Infections (CLABSI) Incidence in the Era of Prevention Practices.
The incidence of central line-associated bloodstream infections (CLABSI) attributed to central venous catheters (CVCs) inserted in the emergency department (ED) is not widely reported. The goal was to report the incidence of ED CLABSI. Secondary goals included determining the effect of a CVC bundle introduced by the hospital infection prevention department to decrease CLABSI during the surveillance period. ⋯ The CLABSI rates in this academic medical center ED were in the range of those reported by the ICU. The effect of ED CLABSI prevention practices requires further research dedicated to surveying ED CLABSI rates.

Multicenter Study
Accuracy of White Blood Cell Count and C-reactive Protein Levels Related to Duration of Symptoms in Patients Suspected of Acute Appendicitis.
Low levels of white blood cell (WBC) count and C-reactive protein (CRP) have been suggested to sufficiently rule out acute appendicitis. The diagnostic value of these tests is likely to depend on the duration of complaints. The aim of this study was to evaluate the accuracy of these inflammatory markers in relation to duration of symptoms in patients suspected of acute appendicitis. ⋯ No WBC count or CRP level can safely and sufficiently confirm or exclude the suspected diagnosis of acute appendicitis in patients who present with abdominal pain of 5 days or less in duration.

Review Meta Analysis
Ketamine-Propofol Versus Propofol Alone for Procedural Sedation in the Emergency Department: A Systematic Review and Meta-analysis.
Propofol is an agent commonly used for procedural sedation and analgesia (PSA) in the emergency department (ED), but it can cause respiratory depression and hypotension. The combination of ketamine-propofol (K-P) is an alternative that theoretically provides a reduction in adverse events compared to propofol. The primary objective of this review was to determine if K-P has a lower frequency of adverse respiratory events in patients undergoing PSA in the ED than propofol alone. Secondary objectives were to compare the proportion of overall adverse events, sedation time, procedure time, and recovery time between K-P and propofol. ⋯ The premise of combining ketamine with propofol is based on the many synergies that theoretically exist between these two agents. In this study, K-P had a lower frequency of adverse respiratory events in patients undergoing PSA in the ED compared to propofol alone.

Multicenter Study Observational Study
Comparison of Clinician Suspicion Versus a Clinical Prediction Rule in Identifying Children at Risk for Intra-abdominal Injuries After Blunt Torso Trauma.
Emergency department (ED) identification and radiographic evaluation of children with intra-abdominal injuries who need acute intervention can be challenging. To date, it is unclear if a clinical prediction rule is superior to unstructured clinician judgment in identifying these children. The objective of this study was to compare the test characteristics of clinician suspicion with a derived clinical prediction rule to identify children at risk of intra-abdominal injuries undergoing acute intervention following blunt torso trauma. ⋯ The derived clinical prediction rule had a significantly higher sensitivity, but lower specificity, than clinician suspicion for identifying children with intra-abdominal injuries undergoing acute intervention. The higher specificity of clinician suspicion, however, did not translate into clinical practice, as clinicians frequently obtained abdominal CT scans in patients they considered very low risk. If validated, this prediction rule can assist in clinical decision-making around abdominal CT use in children with blunt torso trauma.

Randomized Controlled Trial
Just-in-Time to Save Lives: A Pilot Study of Layperson Tourniquet Application.
The objective was to determine whether just-in-time (JiT) instructions increase successful tourniquet application by laypersons. ⋯ Just-in-time instructions increase laypeople's successful application of C-A-T. This pilot study provides evidence that JiT instructions may assist the lay public in providing effective point-of-injury hemorrhage control.
