PURPOSE: The aim of this study was to estimate the amount of CT studies performed in the emergency department of a tertiary hospital that are not indicated by Canadian CT Head Rule (CCHR) guidelines and to analyze factors that contribute to unnecessary examinations. METHODS: A total of 955 brain CT examinations performed for minor head injuries were randomly retrospectively selected. Medical records were assessed for the following parameters: demographics, cause of head trauma, and referring physician's seniority and specialty...

BACKGROUND AND OBJECTIVE: To compare two scales for assessment of patients with mild head injury. The Canadian CT Head Rule (CCHR) and New Orleans Criteria (NOC) according to their diagnostic accuracy in patients attending an emergency department, and to determine the most important predictive values. METHOD: Cross-sectional study in a first-level Hospital in the period of January 2011 to January 2013. Patients with mild head injury criteria were included. All the patients underwent a computed tomography (CT) of the head as part of internal protocol and the CCHR and NOC criteria were recorded for each patient...

BACKGROUND AND PURPOSE: A large degree of variation in clinical practice exists among clinicians evaluating and treating individuals with minor head injuries. Noncontrast head computerized tomography (CT) scans are commonly used to assess for intracranial damage in patients presenting with head injury. This practice is not supported by the evidence and poses harm to patients by increasing exposure to ionizing radiation. This form of radiation exposure increases the risk of developing cancers over the course of the individual's life, and further strains the limited resources of the healthcare system...

In an electronic health record (EHR) chart review of adult ED trauma patients receiving a head CT from 2008-2013 within 14 community EDs, Sharp et al. estimate that approximately 1/3 of computed tomography (CT) scans in head injury are likely avoidable based on the Canadian CT Head Rule (CCHR).(1) The analysis includes 27,240 adult trauma patients receiving head CTs and uses in-depth chart review of 100 random encounters with 2 independent abstractors (with high inter-rater reliability) to adjust the estimated number of avoidable CTs-the top Choosing Wisely initiative for emergency medicine...

BACKGROUND: Patients admitted to emergency departments with traumatic brain injury (TBI) are commonly being treated with oral anticoagulants. In contrast to patients without anticoagulant medication, no guidelines, scores or recommendations exist for the management of mild traumatic brain injury in these patients. We therefore tested whether age as one of the high risk factors of the Canadian head CT rule is applicable to a patient population on oral anticoagulants. METHODS: This cross-sectional analysis included all patients with mild TBI and concomitant oral anticoagulant therapy admitted to the Emergency Department, Inselspital Bern, Switzerland, from November 2009 to October 2014 (n = 200)...

We compared Canadian computed tomography (CT) head rule (CCHR) and New Orleans Criteria (NOC) in predicting important CT findings in patients with mild traumatic brain injury (TBI). We included 142 consecutive patients with mild TBI [Glasgow coma scale (GCS) 13-15] who showed at least one of the risk factors stated in the CCHR or the NOC. We introduced two scores: a Canadian from the CCHR and a New Orleans from the NOC. A patient's score represented a sum of the number of positive items. We examined the relationship between scores or items and the presence of important CT findings...

OBJECTIVES: Minor head trauma accounts for a significant proportion of pediatric emergency department (ED) visits. In children younger than 24 months, scalp hematomas are thought to be associated with the presence of intracranial injury (ICI). We investigated which scalp hematoma characteristics were associated with increased odds of ICI in children less than 17 years who presented to the ED following minor head injury and whether an underlying linear skull fracture may explain this relationship...

INTRODUCTION: High performing clinical decision rules (CDRs) have been derived to predict which head-injured child requires a computed tomography (CT) of the brain. We set out to evaluate the performance of these rules in the Singapore population. MATERIALS AND METHODS: This is a prospective observational cohort study of children aged less than 16 who presented to the emergency department (ED) from April 2014 to June 2014 with a history of head injury. Predictor variables used in the Canadian Assessment of Tomography for Childhood Head Injury (CATCH), Children's Head Injury Algorithm for the Prediction of Important Clinical Events (CHALICE) and Pediatric Emergency Care Applied Research Network (PECARN) CDRs were collected...

BACKGROUND: Overuse of computed tomography (CT) for minor head injury continues despite developed and rigorously validated clinical decision rules like the Canadian CT Head Rule (CCHR). Adherence to this sensitive and specific rule could decrease the number of CT scans performed in minor head injury by 35%. But in practice, the CCHR has failed to reduce testing, despite its accurate performance. OBJECTIVES: The objective was to identify nonclinical, human factors that promote or inhibit the appropriate use of CT in patients presenting to the emergency department (ED) with minor head injury...

BACKGROUND: Economic evaluations provide a unique opportunity to identify the optimal strategies for the diagnosis and management of traumatic brain injury (TBI), for which uncertainty is common and the economic burden is substantial. OBJECTIVE: The objective of this study was to systematically review and examine the quality of contemporary economic evaluations in the diagnosis and management of TBI. METHODS: Two reviewers independently searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, NHS Economic Evaluation Database, Health Technology Assessment Database, EconLit, and the Tufts CEA Registry for comparative economic evaluations published from 2000 onward (last updated on August 30, 2013)...

BACKGROUND: A study was conducted to (1) determine the testing threshold for head computed tomography (CT) in minor head injury in the emergency department using decision analysis with and without costs included in the analysis, (2) to determine which variables have significant impact on the testing threshold, and (3) to compare this calculated testing threshold to the pretest risk estimate previously reported when the Canadian CT Head Rule (CCHR) was applied. It was hypothesized that the CCHR might not identify all patients above the testing threshold...

BACKGROUND: Clinical decision rules (CDRs) can be an effective tool for knowledge translation in emergency medicine, but their implementation is often a challenge. This study examined whether the Theory of Planned Behaviour (TPB) could help explain the inconsistent results between the successful Canadian C-Spine Rule (CCR) implementation study and unsuccessful Canadian CT Head Rule (CCHR) implementation study. Both rules are aimed at improving the accuracy and efficiency of emergency department radiography use in clinical contexts that exhibit enormous inefficiency at the present time...

The Canadian CT Head Rule attempts to standardize the practice of obtaining head computed tomography (CT) scans in patients with minor head injury. Previous research indicates 10 to 35 per cent of CT scans performed do not meet these guidelines. The purpose of this study was to review our use of CT scans in the evaluation of mild traumatic brain injury and to identify 1) unnecessary head CT scans (UHCT); 2) variables associated with UHCT; and 3) associated costs. Using a trauma registry, inclusion criteria were age older than 18 years, Glasgow Coma Scale of 15, and at least one head CT scan...
