Many trauma patients undergo advanced diagnostic imaging before being transferred to a regional trauma centre, but this step can delay definitive care. This study compared the length-of-stay at the primary hospital between patients who underwent CT scans and those who did not.

This was a medical record review of all consecutive trauma cases transferred to a regional trauma centre servicing 2.2 million people during a 2-year period. Two trained abstractors, blind to each other's results, collected data independently.

Of 249 cases, 79 (31%) underwent a CT scan before being transferred. There was no significant difference in the Injury Severity Score between the 2 groups (p = 0.16), yet the CT group remained at the primary hospital approximately 90 minutes longer before transfer (p < 0.001).

A significant proportion of trauma patients transferred to a regional trauma centre undergo CT scanning at the primary hospital. These patients experience an increased length-of-stay of 90 minutes, on average, before transfer. This appears to be a common practice that does not appear to contribute to definitive trauma management.

Inducing mild hypothermia in survivors of cardiac arrest has been demonstrated to improve outcomes. Despite this, other studies have found that few resuscitation physicians have used hypothermia in clinical practice. The objective of this study was to characterize the use of induced hypothermia by Canadian emergency physicians.

An internet-based survey was distributed to all members of the Canadian Association of Emergency Physicians (CAEP). Participants were asked about their experience with, methods for and barriers to inducing hypothermia.

Of the 1328 CAEP members surveyed, 247 (18.6%) responded, with the majority working in academic centres (60.3%). Ninety-five out of 202 respondents (47.0%, 95% confidence interval [CI] 40.8%–53.2%) indicated that they had induced hypothermia in clinical practice and 86 of 212 (40.6%, 95% CI 34.0%–47.2%) worked in a department that had a policy or protocol for the use of induced hypothermia. The presence of a departmental policy or protocol was strongly associated with the use of induced hypothermia (unadjusted odds ratio 10.5, 95% CI 5.3–20.8). Barriers against induced hypothermia cited by respondents included a lack of institutional policies and protocols (38.9%), and of resources (29.4%). Lack of support from consultants was relatively uncommon (8.7%) in Canadian practice.

Only one-half of Canadian emergency physicians report that they have used therapeutic hypothermia in practice. Emergency departments should develop policies or protocols for inducing hypothermia in cardiac arrest survivors to optimize patient outcomes.

Cerebrospinal fluid (CSF) shunt malfunction is one of the most common life-threatening neurosurgical conditions. In the emergency department (ED), imaging techniques to identify shunt malfunction include the shunt series (SS) and CT scanning of the head. We sought to determine the test characteristics of the SS and CT scan for identifying children with shunt malfunction.

We retrospectively reviewed the medical records of children with a CSF shunt who presented to our tertiary care pediatric emergency department and received an SS during a 2-year period from Jan. 1, 2001, to Dec. 31, 2002. A pediatric neuroradiologist reviewed all SS and CT scans. We defined shunt malfunction as present if the child underwent operative shunt revision.

We identified 437 ED visits by 280 children. Forty-seven SS were read as abnormal. A CT scan was performed in 386 (88.3%) cases and 80 were abnormal. Shunt malfunction was identified in 131 (30.0%) children. Sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio and negative likelihood ratio of the SS for identifying cases of shunt malfunction were 30.0%, 95.8%, 72.3%, 75.1%, 7.1 and 0.7, respectively; for the CT scan, they were 61.0%, 82.7%, 64.5%, 80.5%, 3.5 and 0.5, respectively.

Neuroimaging has a low sensitivity for identifying shunt malfunction. Neurosurgical consultation should be sought if shunt malfunction is clinically suspected, despite normal imaging.

For a variety of reasons, many emergency department (ED) visits are classified as less- or nonurgent (Canadian Triage and Acuity Scale [CTAS] level IV and V). A recent survey in a tertiary care ED identified some of these reasons. The purpose of our study was to determine if these same reasons applied to patients presenting with problems triaged at a similar level at a low-volume rural ED.

A 9-question survey tool was administered to 141 CTAS level IV and V patients who attended the South Huron Hospital ED, in Exeter, Ontario, over a 2-week period in December 2006.

Of the 141 eligible patients, 137 (97.2%) completed the study. One hundred and twenty-two patients (89.1%) reported having a family physician (FP) and 53 (38.7%) had already seen an FP before presenting to the ED. Just over one-half of all patients (51.1%) had their problem for more than 48 hours, and 42 (30.7%) stated that they were referred to the ED for care. Fifty-three (38.7%) of the respondents felt they needed treatment as soon as possible. Many patients reported coming to the ED because: 1) their FP office was closed (21.9%); 2) they could not get a timely appointment (16.8%); or 3) the walk-in clinic was closed (24.8%). Only 6 patients (4.4%) specifically stated that they came to the ED because they had no FP. One-third of patients attended the ED because they believed it offered specialized services.

In this rural setting, most less- or nonurgent ED patients had an FP yet they went to the ED because they did not have access to primary care, because they perceived their problem to be urgent or because they were referred for or sought specific services.

We sought to determine the frequency with which fellows in accredited Canadian pediatric emergency medicine (PEM) fellowships perform specific procedures, the level of confidence fellows have in their abilities and whether there are differences in self-perceived success between first- and second-year fellows.

A national survey was developed that focused on 24 PEM procedural skills. The survey asked respondents how many times they had performed these procedures within the past 12 months and within the past 3 years. Respondents were then asked to rate their confidence in successfully performing each of the 24 procedures.

Of the 46 surveys sent to PEM fellows, 32 (70%) were returned. Most respondents were in their second year of training and the vast majority had previous training in pediatrics. In order of frequency, the most common procedures performed were closed reduction of fractures, peripheral intravenous insertion, complex laceration repair and endotracheal intubation. Of the surveyed skills, oropharyngeal/nasopharyngeal airway insertion was deemed the most successful (100% success rate for second-year fellows v. 92.5% success rate for first-year fellows, p = 0.01). Similarly, second-year fellows had a higher self-perceived success rate for intraosseous line insertion than did first-year fellows (95.0% v. 80.0% for second- and first-year fellows, respectively, p < 0.001).

In surveying PEM trainees across Canada, we have described the frequency and self-perceived success rate for 24 important procedures. This information may be helpful for program directors in evaluating future directions and opportunities for training of their PEM trainees.

The Paediatric Canadian Triage and Acuity Scale (PaedCTAS) stipulates that febrile patients who are 3 to 36 months old should be triaged to the PaedCTAS 3 “urgent” category. To optimize resource use, we implemented a protocol enabling these children to be down-triaged to the PaedCTAS 4 “less urgent” category if there was no sign of toxicity. Our objective was to evaluate the safety of this triage protocol modification.

This retrospective cohort study evaluated all patients triaged in an urban tertiary pediatric hospital during a 6-month period between November 22, 2005, and May 22, 2006. Data were retrieved from the emergency department (ED) database and rates of hospitalization and intensive care unit (ICU) admission were compared for 4 groups: all patients triaged as urgent (level 3), all febrile patients from 3 to 36 months old triaged as urgent (level 3), all patients triaged as less urgent (level 4) and all febrile patients aged 3 to 36 months old who were down-triaged to less urgent (level 4).

There were 36 285 total ED visits during the study period, including 3477 febrile children who were 3 to 36 months old. Nurses down-triaged 1869 febrile children (54%) to the level-4 (less urgent) category and left 1322 (38%) in the level-3 (urgent) category. Hospitalization rate for down-triaged febrile patients was similar to that seen for all PaedCTAS 4 patients (2.4% v. 2.8%, 95% confidence interval for difference –0.3% to 1.1%). Down-triaged patients had significantly lower admission rates than those remaining in the level-3 (urgent) category (absolute risk reduction 10.7% standard deviation 1.9%, p < 0.001). No down-triaged patient died or required ICU admission.

Febrile children aged 6 to 36 months who have no signs of toxicity can safely be down-triaged, based on triage nurse clinical judgement, to the less urgent PaedCTAS 4 category. This modification would affect the triage level of approximately 5% of all pediatric ED visits.

Optimal management of severe sepsis in the ED has evolved rapidly. The purpose of these guidelines is to review key management principles for Canadian emergency physicians, utilizing an evidence-based grading system.

Key areas in the management of septic patents were determined by members of the CAEP Critical Care Interest Group (C4). Members of C4 were assigned a question to be answered after literature review, based on the Oxford grading system. After completion, each section underwent a secondary review by another member of C4. A tertiary review was conducted by additional external experts, and modifications were determined by consensus. Grading was based on peer-reviewed publications only, and where evidence was insufficient to address an important topic, a “practice point” was provided based on group opinion.

The project was initiated in 2005 and completed in December 2007. Key areas which were reviewed include the definition of sepsis, the use of invasive procedures, fluid resuscitation, vasopressor/inotrope use, the importance of culture acquisition in the ED, antimicrobial therapy and source control. Other areas reviewed included the use of corticosteroids, activated protein C, transfusions and mechanical ventilation.

Early sepsis management in the ED is paramount for optimal patient outcomes. The CAEP Critical Care Interest Group Sepsis Position Statement provides a framework to improve the ED care of this patient population.

A major role of admission interviews is to assess a candidate's suitability for a residency program. Structured interviews have greater reliability and validity than do unstructured ones. The development of content for a structured interview is typically based on the dimensions of performance that are perceived as important to succeed in a particular line of work. A formal job analysis is normally conducted to determine these dimensions. The dimensions essential to succeed as an emergency medicine (EM) resident have not yet been studied. We aimed to analyze the work of EM residents to determine these essential dimensions.

The “critical incident technique” was used to generate scenarios of poor and excellent resident performance. Two reviewers independently read each scenario and labelled the performance dimensions that were reflected in each. All labels assigned to a particular scenario were pooled and reviewed again until a consensus was reached.

Five faculty members (25% of our total faculty) comprised the subject experts. Fifty-one incidents were generated and 50 different labels were applied. Eleven dimensions of performance applied to at least 5 incidents. “Professionalism” was the most valued performance dimension, represented in 56% of the incidents, followed by “self-confidence” (22%), “experience” (20%) and “knowledge” (20%).

“Professionalism,” “self-confidence,” “experience” and “knowledge” were identified as the performance dimensions essential to succeed as an EM resident based on our formal job analysis using the critical incident technique. Performing a formal job analysis may assist training program directors with developing admission interviews.

Acute myocardial infarction (AMI) remains a major cause of death and β-blockers are known to reduce long-term mortality in post-AMI patients. We sought to determine whether patients receiving β-blockers acutely (within 72 h) following AMI had a lower mortality rate at 6 weeks than patients receiving placebo.

We conducted a systematic review of randomized controlled clinical trials that assessed 6-week mortality and compared β-blockers with placebo in patients randomized within the first 72 hours following AMI. We searched these databases: MEDLINE (1966–2006), EMBASE (1980–2007), Cochrane Central Register of Controlled Trials, Health Star (1966–2007), Cochrane Database for Systematic Reviews, ACP Journal Club (1991–2007), Database of Abstracts of Reviews of Effect (< 1st quarter 2007) and Conference Papers Index (1984–2007). Two blinded reviewers extracted the data and rated study quality using the Jadad score and the adequacy of allocation concealment score, which was adopted by the Cochrane group. We calculated pooled odds ratios (ORs) using a random effect model and performed sensitivity analyses to explore the stability of the overall treatment effect.

We included 18 studies (13 were rated high-quality) with 74 643 enrolled participants and had 5095 deaths. Compared with placebo, adding β-blockers to other interventions within 72 hours after AMI did not result in a statistically significant reduction in 6-week mortality (OR 0.95, 95% confidence interval [CI] 0.90–1.01). When restricted to high quality studies, the OR for 6-week mortality reduction was 0.96 (95% CI 0.91–1.02). We found similar results including studies that enrolled patients within 24 hours after AMI. However, a subgroup analysis that excluded high-risk patients with Killip class III and above showed that β-blockers resulted in a significant reduction in short-term mortality (OR 0.93, 95% CI 0.88–0.99).

Acute intervention with β-blockers does not result in a statistically significant short-term survival benefit following AMI but may be beneficial for low-risk (Killip class I) patients.

We sought to determine if a novel competency-based daily encounter card (DEC) that was designed to minimize leniency bias and maximize independent competency assessments could address the limitations of existing feedback mechanisms when applied to an emergency medicine rotation.

Learners in 2 tertiary academic emergency departments (EDs) presented a DEC to their teachers after each shift. DECs included dichotomous categorical rating scales (i.e., “needs attention” or “area of strength”) for each of the 7 CanMEDS roles or competencies and an overall global rating scale. Teachers were instructed to choose which of the 7 competencies they wished to evaluate on each shift. Results were analyzed using both staff and resident as the units of analysis.

Fifty-four learners submitted a total of 801 DECs that were then completed by 43 different teachers over 28 months. Teachers' patterns of selecting CanMEDS competencies to assess did not differ between the 2 sites. Teachers selected an average of 3 roles per DEC (range 0–7). Only 1.3% were rated as “needs further attention.” The frequency with which each competency was selected ranged from 25% (Health Advocate) to 85% (Medical Expert).

Teachers chose to direct feedback toward a breadth of competencies. They provided feedback on all 7 CanMEDS roles in the ED, yet demonstrated a marked leniency bias.
