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.

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 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.

The objective was to estimate how data errors in electronic health records (EHRs) can affect the accuracy of common emergency department (ED) operational performance metrics. ⋯ Infrequent and small-magnitude data errors in EHR time stamps can compromise a clinical organization's ability to determine accurately if it is meeting performance goals. By understanding the types and frequencies of data errors in an organization's EHR, organizational leaders can use data management best practices to better measure true performance and enhance operational decision-making.

The objective was to determine the frequency of postreduction, hospital-level interventions among children with successful reduction of ileocolic intussusception and identify factors that predict the need for such interventions. ⋯ Clinical decompensation is rare and recurrence is relatively low after an uncomplicated reduction of ileocolic intussusception. However, one in five children required hospital-level interventions after reduction. Children with the intussusception tip at (or proximal to) the hepatic flexure, and those with symptoms for longer than 24 hours, are more likely to require subsequent interventions. Although outpatient management appears safe after a period of observation, caregivers should be counseled about the risk of ongoing symptoms and recurrence.
