This study compared the clinical performance of the Canadian CT Head Rule (CCHR) and the New Orleans Criteria (NOC) for detecting any traumatic intracranial lesion on computed tomography (CT) in patients with a Glasgow Coma Scale (GCS) score of 15. Also assessed were ability to detect patients with "clinically important" brain injury and patients requiring neurosurgical intervention. Additionally, the performance of the CCHR was assessed in a larger cohort of those presenting with GCS of 13 to 15. ⋯ In a U.S. sample of mildly head-injured patients, the CCHR and the NOC had equivalently high sensitivities for detecting any traumatic intracranial lesion on CT, clinically important brain injury, and neurosurgical intervention, but the CCHR was more specific. A larger cohort will be needed to validate these findings.

Lack of adequate risk adjustment methodologies has hindered the progress of emergency medicine health services research. The authors hypothesized that a consensus-derived, diagnosis-based severity classification system (SCS) would be significantly associated with actual measures of emergency department (ED) resource use and could ultimately be used to examine severity-adjusted outcomes across patient populations. ⋯ The SCS demonstrates validity in its strong association with actual ED resource use. The use of readily available ICD-9 diagnosis codes makes the SCS useful as a risk adjustment tool for health services research.

Patient acuity triage systems can play an important role in supporting patient safety and emergency department (ED) operations. In 2003, the boards of the American College of Emergency Physicians (ACEP) and the Emergency Nurses Association (ENA) approved a joint statement calling for hospitals to adopt a reliable, valid, five-level triage scale such as the Emergency Severity Index (ESI). Still, there appears to be considerable variation in use of triage acuity systems in the United States, with many hospitals using three- and four-level systems that have not been validated. The purpose of this effort was to measure the use of various triage acuity systems in U.S. hospitals. ⋯ Among our sample of more than 3,000 hospitals, the ESI was the most commonly used triage system, and more patients were triaged using the ESI than any other triage acuity system. Still, there is an opportunity to further promote the adoption of validated, reliable triage systems.

Multicenter Study
Is a standardized questionnaire useful for tubal rupture screening in patients with ectopic pregnancy?
Physical examination, ultrasonography, and laboratory tests fail to reliably establish the preoperative diagnosis of tubal rupture in patients with ectopic pregnancy (EP), leading to a high rate of diagnostic laparoscopy. The aim of this study was to construct and to evaluate a clinical prediction rule for tubal rupture screening based on a self-assessment questionnaire, among patients with EP. ⋯ These results suggest that a standardized questionnaire may contribute to ruling out tubal rupture in patients with EP.
