Cervical spine injuries (CSIs) after blunt trauma in children are rare, but cause substantial morbidity and mortality. Emergency medical services (EMS) and emergency department (ED) providers routinely use spinal precautions and cervical spine imaging, respectively, during the management of children experiencing blunt trauma. These practices lack evidence, and there is concern that they may be harmful. A pediatric CSI risk assessment tool is needed to inform EMS and ED provider decision making. Creating this tool requires prospective data collection from EMS and ED providers at the time of patient evaluation. The purpose of this article is to describe the methods used to prospectively capture paired EMS and ED provider observations of children cared for after blunt trauma. Given the rarity of prospective observational research with EMS, the novel use of Research Electronic Data Capture (REDCap) in this study, and the potential to inform future studies, we are publishing our methodology in advance of outcome data related to the risk assessment tool. ⋯ Our method of data collection demonstrates the ability to prospectively capture paired observations from EMS and ED personnel for children undergoing evaluation after blunt trauma. While this methodology will be used to implement and evaluate a CSI tool in future studies, it may also be adapted to studies requiring prospective data collection from EMS and ED personnel.

Multicenter Study
Association of Hospital Resources and Imaging Choice for Appendicitis in Pediatric Emergency Departments.
Abdominal pain and concern for appendicitis are common chief complaints in patients presenting to the pediatric emergency department (PED). Although many professional organizations recommend decreasing use of computed tomography (CT) and choosing ultrasound as first-line imaging for pediatric appendicitis, significant variability persists in imaging utilization. This study investigated practice variation across children's hospitals in the diagnostic imaging evaluation of appendicitis and determined hospital-level characteristics associated with the likelihood of ultrasound as the first imaging modality. ⋯ Across children's hospitals, significant practice variation exists regarding diagnostic imaging in the evaluation of patients with appendicitis. Variation in hospital-level resources may impact the diagnostic evaluation of patients with appendicitis. Availability of 24-hour in-house ultrasound significantly increases the likelihood of ultrasound as first imaging and decreases CT scans. Hospitals aiming to increase the use of ultrasound should consider adding 24-hour in-house coverage.

Loss to follow-up of enrolled patients (a.k.a. attrition) is a major threat to study validity and power. Minimizing attrition can be challenging even under ideal research conditions, including the presence of adequate funding, experienced study personnel, and a refined research infrastructure. ⋯ The seven areas of approach to minimize attrition in this study focused on patient selection, baseline contact data collection, patient incentives, patient tracking, central phone banks, local enrollment site assistance, and continuous performance monitoring. Appropriate study design, including consideration of these methods to reduce attrition, will be time well spent and may improve study validity.

Opioid overdose mortality has tripled in the United States since 2000 and opioids are responsible for more than half of all drug overdose deaths, which reached an all-time high in 2014. Opioid overdoses resulting in death, however, represent only a small fraction of all opioid overdose events and efforts to improve surveillance of this public health problem should include tracking nonfatal overdose events. International Classification of Disease (ICD) diagnosis codes, increasingly used for the surveillance of nonfatal drug overdose events, have not been rigorously assessed for validity in capturing overdose events. The present study aimed to validate the use of ICD, 9th revision, Clinical Modification (ICD-9-CM) codes in identifying opioid overdose events in the emergency department (ED) by examining multiple performance measures, including sensitivity and specificity. ⋯ Tracking opioid overdose ED visits by diagnostic coding is fairly specific but insensitive, and coding was not influenced by administration of naloxone or the specific opioids involved. The reason for the high rate of missed cases is uncertain, although these results suggest that a more clearly defined case definition for overdose may be necessary to ensure effective opioid overdose surveillance. Changes in coding practices under ICD-10 might help to address these deficiencies.

In 2006, the American College of Surgeons' Committee on Trauma and the Centers for Disease Control and Prevention released field triage guidelines with special consideration for older adults. Additional considerations for direct transport to a Level I or II trauma center (TC) were added in 2011, reflecting perceived undertriage to TCs for older adults. We examined whether age-based disparities in TC care for severe head injury decreased following introduction of the 2011 revisions. ⋯ Although patterns of increased TC treatment for all groups with severe head trauma indicate improvements, age-based disparities persisted.
