SummaryBackground: Overuse of cranial computed tomography scans in children with blunt head trauma unnecessarily exposes them to radiation. The Pediatric Emergency Care Applied Research Network (PECARN) blunt head trauma prediction rules identify children who do not require a computed tomography scan. Electronic health record (EHR) based clinical decision support (CDS) may effectively implement these rules but must only be provided for appropriate patients in order to minimize excessive alerts.Objective: To develop, implement and evaluate site-specific groupings of chief complaints (CC) that accurately identify children with head trauma, in order to activate data collection in an EHR.Methods: As part of a 13 site clinical trial comparing cranial computed tomography use before and after implementation of CDS, four PECARN sites centrally developed and locally implemented CC groupings to trigger a clinical trial alert (CTA) to facilitate the completion of an emergency department head trauma data collection template. We tested and chose CC groupings to attain high sensitivity while maintaining at least moderate specificity.Results: Due to variability in CCs available, identical groupings across sites were not possible. We noted substantial variability in the sensitivity and specificity of seemingly similar CC groupings between sites. The implemented CC groupings had sensitivities greater than 90% with specificities between 75–89%. During the trial, formal testing and provider feedback led to tailoring of the CC groupings at some sites.Conclusion: CC groupings can be successfully developed and implemented across multiple sites to accurately identify patients who should have a CTA triggered to facilitate EHR data collection. However, CC groupings will necessarily vary in order to attain high sensitivity and moderate-to-high specificity. In future trials, the balance between sensitivity and specificity should be considered based on the nature of the clinical condition, including prevalence and morbidity, in addition to the goals of the intervention being considered.Citation: Deakyne SJ, Bajaj L, Hoffmann J, Alessandrini E, Ballard DW, Norris R, Tzimenatos L, Swietlik M, Tham E, Grundmeier RW, Kuppermann N, Dayan PS.

OBJECTIVE: To verify the prevalence of acute hyperglycemia in children with head trauma stratified by the Glasgow coma scale (GCS). METHOD: A prospective cross-sectional study carried out with information from medical records of pediatric patients presenting with head injury in the emergency room of a referral emergency hospital during a one year period. We considered the cut-off value of 150 mg/dL to define hyperglycemia. RESULTS: A total of 340 children were included and 60 (17.6%) had admission hyperglycemia. Hyperglycemia was present in 9% of mild head trauma cases; 30.4% of those with moderate head trauma and 49% of severe head trauma. We observed that among children with higher blood glucose levels, 85% had abnormal findings on cranial computed tomography scans. CONCLUSION: Hyperglycemia was more prevalent in patients with severe head trauma (GCS <8), regardless if they had or not multiple traumas and in children with abnormal findings on head computed tomography scans.

The literature reports delayed intracranial hemorrhage (ICH) after blunt trauma in patients taking preinjury anticoagulant and antiplatelet (AC/AP) medications. We sought to evaluate the incidence of delayed ICH at our institution and hypothesize that patients taking AC/AP medications who are found to have a negative first computed tomography (CT) scan will not require a second CT scan. A total of 303 patients were retrospectively reviewed. Age, gender, mechanism of injury, international normalized ratio (INR), initial and secondary cranial CT findings, and outcomes were recorded. One hundred sixty-eight (55.4%) were found to be taking AP/AC medications. Ninety-six (57%) were male and 72 (43%) female. Aspirin use was 42.8 per cent (72 of 168), clopidogrel next (39 of 168 [23.0%]), and warfarin least (18 of 168 [10.7%]). One hundred sixty-six (98.8%) presented with significant findings on the first CT scan. Fourteen (87.5%) of the 16 patients with an INR 2.0 or higher presented with an ICH on the first CT. Ninety percent of patients with an INR 1.5 or higher presented with positive findings on the first CT scan. One hundred per cent of patients with an INR 3.0 or higher presented with an ICH on the first CT scan. The incidence of a delayed ICH was two of 168 (1.19%). Of those two patients with a delayed ICH, 100 per cent were taking warfarin and had an INR greater than 2.0. The incidence of delayed ICH was 1.19 per cent. The protocol requiring a second CT scan for all patients on AC/AP medications after a negative first CT scan should be questioned. For patients with blunt head trauma taking warfarin or a warfarin–aspirin combination, a repeat cranial CT scan after a negative initial CT is acceptable. For patients taking clopidogrel, a period of observation may be warranted.

OBJECTIVE: To identify which pediatric patients with mild head trauma are candidates for skull radiographs or cranial computed tomography (CCT) scans. METHOD: Patients with mild head trauma aged from 0 to 19 years presenting to the Emergency Department of a trauma centre from Salvador City, Brazil, between May 2007 and May 2008. RESULTS: A total of 1888 mild head trauma patients were admitted; mean age was 7.4 (±5.5) years. A total of 1956 skull radiographs and 734 CCT scans were performed. About 44.4% patients with Glasgow coma score (GCS) 13 and 55.4% with GCS 14 had abnormal CCT scans. In patients with multiple traumas, 16% had abnormal findings on CCT scans. CONCLUSION: We strongly recommend routine CCT studies to patients with GCS of 13 and 14 or to multiple trauma victims, independently of score. Routine screening skull radiographs were not useful in the evaluation of mild head trauma patients in this study.
