This study was designed to validate the "San Francisco Syncope Rule". This set of rules was derived by Quinn et. al. to help guide the treatment of patients evaluated in the Emergency Department who had an episode of syncope (passed out) or near syncope (almost passed out). A rule that considers patients with an abnormal ECG, a complaint of shortness of breath, hematocrit less than 30%, systolic blood pressure less than 90 mm Hg, or a history of congestive heart failure was sh...
The aim of this study is to assess the effectiveness and usefulness of a simple one word mnemonic in the memory retention of the different components of the Canadian CT Head Rule (CCHR) in senior medical students and interns. The CCHR, a clinical decision rule used by emergency physicians to determine the need of head CT in the context of minor traumatic brain injury (mTBI). A rapid recall of the rule in the clinical setting would be expected to improve its utilization and over...
Early rule-in or rule-out of myocardial infarction (MI) is essential in patients presenting to the Emergency Department with chest pain. Recently, the European Society of Cardiology has suggested an accelerated 0h/1h algorithm to rule-in or rule-out MI as a valid alternative to the standard 0h/3h approach. So far, the 0h/1h algorithm has only been validated for certain high-sensitive Troponin assays. Moreover, it is unknown if MI can be ruled-out by measuring hs-cTn already at ...
The main objective of this study is to verify whether a new clinical decision rule identifying patients diagnosed with unprovoked blood clots who have a low risk of recurrence can safely stop oral anticoagulant therapy after 5-7 months of treatment.
To date, the Pediatric Emergency Care Applied Research Network (PECARN) rule for identifying children who are at very low risk of clinically-important traumatic brain injuries after minor head trauma has not been validated prospectively in an independent population. Our goal was to evaluate the diagnostic performance of the PECARN clinical decision rule in a French pediatric population in multiple clinical settings.
Management of NSTEMI in emergency departements represent 10% of the global activity. Since the the last European Society of Cardiology recommendation the use of an 1 hour rule-in and rule-out protocol is recommended combined with high-sensitivity troponin. But studies show 3% of the patients are false negative using this protocol. This study aims at analysing the feasibility of this protocol in an Emergency Departement and the security of this protocol if combined with a pre-tr...
This is prospective cohort study, in pregnant women who present with signs and symptoms of possible deep vein thrombosis. All patients will have the same method of assessment of their DVT symptoms (the LEFt clinical decision rule will be applied and D-dimer test will be done) to determine if a compression ultrasound is required. All patients will be followed for a period of 3 months.
This study will evaluate the ability of Coronary Computed Tomography Angiography (CCTA), used as a first-line diagnostic tool in women with stable chest pain and low risk for Coronary Artery Disease (CAD), to reduce the number of women requiring more than one diagnostic test to rule in or rule out CAD. Half of the participants will undergo CCTA as the first test to investigate stable chest pain, while the other half will undergo any test ordered by their family physician.
Acute coronary syndrome (ACS) is a major health problem and its diagnosis remains a challenge for the emergency physician. The management of a suspected ACS is well codified, based on troponin assays, renewed if necessary. Conversely, the criteria leading to initiate a diagnostic procedure in chest pain to the Emergency department are unclear. The fear is, firstly, to miss a potentially life treating diagnosis and, secondly, exposing many patients to unnecessary examinations. ...
What combination of ≤ 6 clinical variables will give the highest specificity for indicating significant shoulder injuries (fractures or dislocations) with a set sensitivity of ≥ 97%? Although shoulder trauma is a common injury, there is no clinical decision rule to determine the necessity for radiography for these traumas. With this trial the investigators aim to develop such a rule to reduce the amount of radiographs without missing any significant injuries. The pr...
The purpose of this study is to validate a clinical decision rule for the management of minor head trauma in infants aged less than two years, constructed with the intention of minimizing the rate of computed tomography scans ordering.
Evaluate the reproducibility and validate a posteriori a new rule of clinical decision on a multi-center population of children with a post-chemotherapy febrile neutropenia
The study is a prospective multi-centre observational study to evaluate a portable magnetocardiograph device for the rule-out of acute coronary syndrome (ACS) in patients who present to the emergency department with chest pain and other symptoms consistent with ACS.
Background: Despite their potential health and social benefits, adoption and use of improved cookstoves has been low throughout much of the world. Explanations for low adoption rates of these technologies include prices that are not affordable for the target populations, limited opportunities for households to learn about cookstoves through peers, and perceptions that these technologies are not appropriate for local cooking needs. The P3 project employs a novel experimen...
A prospective multi-centre observational study to validate the diagnostic accuracy of a transportable magnetocardiograph device for acute coronary syndrome (ACS), focusing on rule-out capability, in patients who present to the emergency department with chest pain symptoms consistent with ACS.
The purpose of this study is to determine whether patients who meet the criteria of the clinical prediction rule for spinal manipulation may respond more favorably to repeated exercises according to a direction of preference (what makes the symptoms decrease). The investigators do not know which of these two commonly-used treatments (manipulation or specific exercise) is better to treat low back pain.
Every year > 50.000 people in Denmark are hospitalized with a suspected acute myocardial infarction (AMI). The majority has other explanations of their chest discomfort and most are discharged again without any initiation of treatment. Still, the suspicion dictates acute ambulance deployment, hospital admission to a highly specialized cardiac unit, cardiac surveillance and cardiac troponin blood sampling. The novel biomarker copeptin, a byproduct of vasopressin production, is r...
Registry of an interventional Study-proved Strategy (BIC-8) using Copeptin and Troponin for the Early Rule-Out of Acute Myocardial Infarction (AMI) in Patients with Suspected Acute Coronary Syndrome (ACS) and a low-to intermediate risk profile.
This study evaluates whether the implementation of a prediction rule for postoperative nausea and vomiting changes physician behaviour, improves patient outcome and improves cost-effectiveness of treatment of postoperative nausea and vomiting.
Falls are the leading cause of traumatic death in the elderly with head injury causing half of these deaths. Each year, one in three adults over the age of 65 (seniors) fall, and half of these seniors seek treatment at a hospital emergency department (ED). There is a major evidence gap in the study of brain injury diagnosis in seniors, which is problematic for emergency physicians since the number of fall-associated head injuries is rising. ED diagnostic tools for risk stratifi...
Validation of modified HEART score as a rule-out criterion for MACE at 6 weeks: a 2 centre prospective observational cohort with a direct comparison to TIMI, GRACE and high sensitive troponin T at limits of detection Detailed description: The HEART score, as defined previously by Backus et al1, is a risk score specifically developed for acute chest pain/ suspected acute coronary syndrome. The conventional scoring system for the troponin component of HEART is as follows:...
Each year, Canadian emergency department physicians treat 600,000 patients with head injury. Many of these are adults with "minor head injury", i.e. loss of consciousness or amnesia and a Glasgow Coma Scale (GCS) score of 13-15. Only 6.2% of these "minor" patients have some acute injury on computed tomography (CT scan) and only 0.5% have an epidural hematoma requiring surgery. Among Canadian teaching hospital emergency departments, we have shown a fourfold variation in use of C...
