The Canadian CT Head Rule for patients with minor head injury
Regional variation in out-of-hospital cardiac arrest incidence and outcome.
In this study involving 10 geographic regions in North America, there were significant and important regional differences in out-of-hospital cardiac arrest incidence and outcome.
Clinical prediction rules. A review and suggested modifications of methodological standards.
Although clinical prediction rules comply with some methodological criteria, for other criteria, better compliance is needed.
Excluding Pulmonary Embolism at the Bedside without Diagnostic Imaging: Management of Patients with Suspected Pulmonary Embolism Presenting to the Emergency Department by Using a Simple Clinical…
A diagnostic algorithm based on a simple model and a non-enzyme-linked immunosorbent d-dimer assay was used in patients presenting to emergency departments with suspected pulmonary embolism to demonstrate the safety of excluding the diagnosis of pulmonary emblism in an emergency department using diagnostic algorithms based on pretest probability and d-Dimer assay results.

The LACE index can be used to quantify risk of death or unplanned readmission within 30 days after discharge from hospital and could be used with both primary and administrative data.
Users' guides to the medical literature: XXII: how to use articles about clinical decision rules. Evidence-Based Medicine Working Group.
Level 1 CDRs have the potential to inform clinical judgment, to change clinical behavior, and to reduce unnecessary costs, while maintaining quality of care and patient satisfaction.
Methodologic standards for the development of clinical decision rules in emergency medicine.
The Canadian C-spine rule versus the NEXUS low-risk criteria in patients with trauma.
For alert patients with trauma who are in stable condition, the CCR is superior to the NLC with respect to sensitivity and specificity for cervical-spine injury, and its use would result in reduced rates of radiography.
CATCH: a clinical decision rule for the use of computed tomography in children with minor head injury
A decision rule based on recursive partitioning that identifies children at two levels of risk for CT of the head and has the potential to standardize and improve the use of CT for children with minor head injury is developed.
Comparison of the Canadian CT Head Rule and the New Orleans Criteria in patients with minor head injury.
For patients with minor head injury and GCS score of 15, the Canadian CT Head Rule and the NOC have equivalent high sensitivities for need for neurosurgical intervention and clinically important brain injury, but the CCHR has higher specificity for important clinical outcomes than does the N OC, and its use may result in reduced imaging rates.
