Multicenter Study Observational Study
Economic Analysis of Diagnostic Imaging in Pediatric Patients With Suspected Appendicitis.
The use of computed tomography (CT) and ultrasound (US) in patients with acute abdominal pain has substantial variation across pediatric emergency departments (EDs). This study compares the cost of diagnosing and treating suspected appendicitis across a multicenter network of children's hospitals. ⋯ Our results provide support for US as the primary imaging modality for appendicitis. Sites that preferentially utilized US had lower costs per case than sites that primarily used CT. Imaging rates across sites varied due to practice patterns and resulted in a significant cost consequence without higher rates for negative appendectomies or missed appendicitis cases.

Data suggest that clinicians, when evaluating pediatric patients with blunt head trauma, may be overordering head computed tomography (CT). Prior decision instruments (DIs) aimed at aiding clinicians in safely forgoing CTs may be paradoxically increasing CT utilization. This study evaluated a novel DI that aims for high sensitivity while also improving specificity over prior instruments. ⋯ The Pediatric NEXUS Head CT DI reliably identifies blunt trauma patients who require head CT imaging and could significantly reduce the use of CT imaging.

Acute kidney injury (AKI) is a significant risk factor for morbidity and mortality in children. Little is known about community-acquired AKI (CA-AKI) in the pediatric emergency department (PED). Early recognition of AKI allows for nephroprotective measures. The goal of this investigation was to determine the incidence of CA-AKI and the frequency of clinician identified CA-AKI to better inform future nephroprotective interventions. ⋯ CA-AKI remains an underrecognized entity in the PED. Better tools for early recognition of AKI in the busy PED environment are needed.

The risk of radiation exposure from computed tomography (CT) imaging in children is well recognized. Patient history and physical examination findings, including costal margin tenderness (CMT), influence a physician's decision to image a child with blunt torso trauma. The objective of this study was to determine the importance of CMT for identifying children with intraabdominal injuries (IAI) found on CT and IAI undergoing acute intervention. ⋯ The risk of IAI associated with isolated CMT is minimal. For children with blunt abdominal trauma and isolated CMT, abdominal CT scan is of low yield.

Among emergency physicians, there is wide variation in admitting practices for patients who suffered a mild traumatic brain injury (TBI) with an intracranial hemorrhage (ICH). The purpose of this study was to evaluate the effects of implementing a protocol in the emergency department (ED) observation unit for patients with mild TBI and ICH. ⋯ While there was no difference in EDOU LOS, implementing a low-risk mild TBI and ICH protocol in the EDOU may decrease the rate of inpatient admissions from the EDOU. A protocol-driven observation unit may help physicians by standardizing eligibility criteria and by providing guidance on management. As the propensity score method limits our ability to create a straightforward predictive model, a future larger study should validate the results.
