The Canadian CT Head Rule for patients with minor head injury
TLDR
The Canadian CT Head Rule is developed, a highly sensitive clinical decision rule for use of CT that has the potential to significantly standardise and improve the emergency management of patients with minor head injury. Expand
Regional variation in out-of-hospital cardiac arrest incidence and outcome.
TLDR
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. Expand
Clinical prediction rules. A review and suggested modifications of methodological standards.
TLDR
Although clinical prediction rules comply with some methodological criteria, for other criteria, better compliance is needed. Expand
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
TLDR
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. Expand
Derivation and validation of an index to predict early death or unplanned readmission after discharge from hospital to the community
TLDR
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. Expand
Users' guides to the medical literature: XXII: how to use articles about clinical decision rules. Evidence-Based Medicine Working Group.
TLDR
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. Expand
Methodologic standards for the development of clinical decision rules in emergency medicine.
TLDR
The 6 major stages in the development and testing of a new clinical decision rule are considered and a number of standards within each stage are discussed. Expand
CATCH: a clinical decision rule for the use of computed tomography in children with minor head injury
TLDR
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. Expand
Comparison of the Canadian CT Head Rule and the New Orleans Criteria in patients with minor head injury.
TLDR
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. Expand
The Canadian C-spine rule versus the NEXUS low-risk criteria in patients with trauma.
TLDR
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. Expand
