Underutilization of acetylsalicylic acid for acute coronary syndromes in the emergency department
Authors: Dufresne François , Blouin Danielle , Xue Xiaoqing , Afilalo Marc
Published: July 2016

Objective:

Acetylsalicylic acid (ASA) is a simple and cost-effective treatment for acute coronary syndromes (ACS). Our objectives were to determine the frequency of ASA administration in the emergency department (ED) for patients with acute myocardial infarction or unstable angina, and to identify patient characteristics associated with its administration.

Methods:

This is a retrospective chart review of patients discharged with a final diagnosis of ACS. Data on age, gender, mode of presentation, presence of chest pain at triage, administration of ASA or not in the ED, dosage and form of ASA received, timing of administration, presence of contraindications to ASA and use of regular ASA prior to ED presentation were recorded.

Results:

Six hundred and one charts were analyzed. Five hundred and fifty patients (91.5%) received ASA. Only 444 (73.9%) of these 550 patients were administered the ASA appropriately, according to the American Heart Association / American College of Cardiology (AHA/ACC) guidelines. Univariate analysis showed that chart notes “Transport by ambulance,” “Allergy to ASA” and “Gastrointestinal bleed” were associated with a lower probability of the patient being administered ASA. If a patient was noted as taking ASA regularly, it increased the chance of this patient being administered ASA in the ED.

Conclusion:

Although the study ED performed well, administering ASA to 91.5% of patients with ACS, only 73.9% of the patients who received ASA were administered the ASA appropriately, as recommended in the AHA/ACC guidelines. Educational strategies and system changes are necessary to increase the proportion of eligible ACS patients who receive appropriate ASA therapy.
Does the Canadian Emergency Department Triage and Acuity Scale identify non-urgent patients who can be triaged away from the emergency department?
Authors: Vertesi Les
Published: July 2016

Introduction:

Non-urgent visits comprise a significant proportion of visits to most emergency departments (EDs). Given the severe overcrowding issues faced by many EDs, the use of theCanadian Emergency Department Triage and Acuity Scale(CTAS) to identify patients who could be managed elsewhere seems to be an obvious way to reduce the pressure on the ED and “solve” the overcrowding problem.

Objective:

To quantify the resource implications, in terms of stretcher use and waiting times, related to non-urgent patient visits and to estimate the potential impact on ED flow of redirecting these patients to alternate primary care settings.

Methods:

Retrospective database audit in an urban referral hospital ED. For this study, patients triaged as either CTAS Levels IV or V were considered “non-urgent.”

Results:

Non-urgent patients comprised 30% of ED visits, but less than 5% of all those needing stretchers, along with their associated nursing resources. The longer waits consisted almost entirely of waits for available stretchers and would therefore have remained essentially unaffected. In spite of being labelled “non-urgent” by CTAS criteria, 7.3% of all patients requiring admission came from this group.

Conclusions:

Non-urgent patients consume a small fraction of the ED stretchers and acute-care resources; therefore, strategies aimed at diverting non-urgent patients are unlikely to improve access for more urgent patients. Using the CTAS to identify patients for diversion away from the ED is measurably unsafe and will lead to inappropriate refusal of care for many patients requiring hospital treatment.
Consultation outcomes in the emergency department: exploring rates and complexity
Authors: Woods Robert A. , Lee Renee , Ospina Maria B. , Blitz Sandra , Lari Harris , Bullard Michael J. , Rowe Brian H.
Published: July 2016

Objective:

Consultation is a common and important aspect of emergency department (ED) care. We prospectively examined the consultation rates, the admission rates of consulted patients, the emergency physician (EP) disposition prediction of consulted patients and the difficult consultations rates in 2 tertiary care hospitals.

Methods:

Attending EPs recorded consultations during 5 randomly selected shifts over an 8-week period using standardized forms. Subsequent computer outcome data were extracted for each patient encounter, as well as demographic data from the ED during days in which there was a study shift.

Results:

During 105 clinical shifts, 1930 patients were managed by 21 EPs (median 17 patients per shift; interquartile range 14–23). Overall, at least 1 consultation was requested in 38% of patients. More than one-half of the patients (54.3%) who received a consultation were admitted to the hospital. Consultation proportions were similar between males and females (51% v. 49%,p= 0.03). Consultations occurred more frequently for patients who were older, had higher acuity presentations, arrived during daytime hours or arrived by ambulance. The proportion of agreement between the EP's and consultant's opinion on the need for admission was 89% (κ = 0.77, 95% confidence interval 0.72–0.83). Overall, 92% of patents received 1 consultation. Six percent of the consultations were perceived as “difficult” by the EPs (defined as the EP's subjective impression of difficulties with consultation times, accessibility and availability of consultants, and the interaction with consultants or disposition issues).

Conclusion:

Consultation is a common process in the ED. It often results in admission and is predictable based on simple patient factors. Because of perceived difficulty with consultations, strategies to improve the EP consultation process in the ED seem warranted.
Withdrawal from gamma-hydroxybutyrate, 1,4-butanediol and gamma-butyrolactone: a case report and systematic review
Authors: Wojtowicz Jeremy M. , Yarema Mark C. , Wax Paul M.
Published: July 2016

1,4-Butanediol (1,4-BD) is an industrial solvent that is metabolized to gamma-hydroxybutyrate (GHB), a gamma-aminobutyric acid agonist and central nervous system depressant. GHB and its analogues are popular drugs of abuse. Withdrawal from these agents is characterized by autonomic instability and altered mental status. We report a case of withdrawal from 1,4-BD lasting 6 days and complicated by new onset of seizures and rhabdomyolysis. In addition, we conducted a systematic review of the English literature pertaining to withdrawal from GHB, 1,4-BD and gamma-butyrolactone (GBL). Data collected from source articles included last use prior to symptom onset, clinical features on presentation, duration of symptoms and outcome. Twenty-seven studies with 57 episodes of withdrawal were included. Thirty-six cases (63%) involved GHB, 3 cases (5%) involved 1,4-BD and 18 (32%) involved GBL. The most common patient symptoms were tremor (67%), hallucinations (63%), tachycardia (63%) and insomnia (58%). Seizures and rhabdomyolysis each occurred in 7% of cases, but only 1 death occurred. Emergency physicians must consider withdrawal from these agents when patients present with clinical features suggestive of a sedative-hypnotic withdrawal syndrome.
Is computerized tomography of trauma patients associated with a transfer delay to a regional trauma centre?
Authors: Onzuka Justin , Worster Andrew , McCreadie Bill
Published: July 2016

Objective:

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.

Methods:

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.

Results:

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).

Conclusion:

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.
Do β-blockers reduce short-term mortality following acute myocardial infarction? A systematic review and meta-analysis
Authors: Al-Reesi Abdullah , Al-Zadjali Nabil , Perry Jeff , Fergusson Dean , Al-Shamsi Mohammed , Al-Thagafi Majid , Stiell Ian
Published: July 2016

Objective:

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.

Methods:

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.

Results:

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).

Conclusion:

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.
Experiences of substance-using suicidal males who present frequently to the emergency department
Authors: Spence Julia M. , Bergmans Yvonne , Strike Carol , Links Paul S. , Ball Jeffrey S. , Rhodes Anne E. , Watson William J. , Eynan Rahel , Rufo Claire
Published: July 2016

Objective:

This qualitative study investigated the repeated use of the emergency department (ED) by men with a history of suicidal behaviour and substance abuse to understand the needs and barriers to care for this high-risk group. Identification of common themes from interviews with patients and health care workers can serve as a basis for improved ED-based interventions.

Methods:

Using semistructured interviews, patients, ED staff and family physicians were asked about needs of the aformentioned group. Twenty-five patients were interviewed and completed questionnaires regarding their substance use, aggression, parasuicidal behaviour, alexithymia and childhood trauma. In addition, 27 staff members were interviewed. Interviews were tape-recorded, transcribed and qualitatively analyzed using an iterative coding process.

Results:

Of the 25 patients, 23 (96%) had a mood or anxiety disorder and 18 (75%) had borderline personality disorder. One-half of the patients scored high and another quarter scored moderate on alexithymia testing. The ED was viewed as a last resort despite seeking help. Frustration was felt by both patients and staff regarding difficult communication, especially during an acute crisis.

Conclusion:

The ED plays an important role in the provision of care for men with recurrent suicidal behaviour and substance abuse. Some of the diagnoses and problems faced by these patients are beyond the purview of the ED; however, staff can identify mutual goals for crisis interventions, allow for frequent communication and seek to de-escalate situations through the validation of the stress patients are experiencing.
Assessing competence in emergency medicine trainees: an overview of effective methodologies
Authors: Sherbino Jonathan , Bandiera Glen , Frank Jason R.
Published: July 2016

How do we define competence in emergency medicine (EM), and how do we know when a resident has achieved it? In recent years, the idea of physician competence has become widely recognized as being multidimensional. This has resulted in an emphasis on competency-based education and assessment. We describe an up-to-date model to assess competence in EM. An overview of appropriate EM assessment tools is provided, along with their significant strengths and limitations. Sample behaviours representative of core competencies commonly assessed in EM training are matched to appropriate assessment tools. This review may serve as an introductory resource for EM clinicians, teachers and educators involved in EM trainee assessment.
Traumatic occurrence of chest wall tamponade secondary to subcutaneous emphysema
Authors: Perraut Michael , Gilday Daniel , Reed Gordon
Published: July 2016

Subcutaneous emphysema is a physical finding that itself is usually perceived as benign yet rarely may, in and of itself, be life-threatening. We present an unusual case of a 67-year-old woman who developed delayed severe subcutaneous emphysema and tension pneumothorax from a rib fracture subsequent to a fall. We review the pathophysiology, manifestations and management options of this disorder. In patients whose clinical condition allows it, chest tube placement prior to intubation should be considered. Furthermore, positive end-expiratory pressure should be minimized. We present a case that illustrates how subcutaneous emphysema itself can be a potential cause of respiratory failure and tamponade physiology. In our case, a patient with traumatic subcutaneous emphysema developed respiratory failure and clinical deterioration after the introduction of positive pressure ventilation. In such rare scenarios, care should be taken to consider the absolute need for positive pressure ventilation without surgical decompression.
Stable fracture of the pubic rami: a rare cause of life-threatening bleeding from the inferior epigastric artery managed with transcatheter embolization
Authors: Loffroy Romaric , Yeguiayan Jean-Michel , Guiu Boris , Cercueil Jean-Pierre , Krausé Denis
Published: July 2016

Extraperitoneal bleeding from the inferior epigastric artery (IEA) and its branches is a rare complication of blunt pelvic trauma; however, it can result in life-threatening hemorrhage, even in cases of minimally displaced fractures of the pelvic ring. We report the case of a patient who had post-traumatic pelvic hematoma and cardiovascular collapse caused by avulsion of the right pubic branch of the IEA related to undisplaced fractures of the pubic rami. CT scanning followed by angiography showed leakage of contrast from the IEA. Transcatheter arterial embolization was performed to successfully control the hemorrhage. There have been very few previous reports of IEA injury related to stable fractures of the pubic rami successfully treated by transcatheter arterial embolization.
An interventional study to improve the quality of analgesia in the emergency department
Authors: Yanuka Michael , Soffer Dror , Halpern Pinchas
Published: July 2016

Objective:

We sought to document the adequacy of acute pain management in a high-volume urban emergency department and the impact of a structured intervention.

Methods:

We conducted a prospective, single-blind, pre- and postintervention study on patients who suffered minor-to-moderate trauma. The intervention consisted of structured training sessions on emergency department (ED) analgesia practice and the implementation of a voluntary analgesic protocol.

Results:

Preintervention data showed that only 340 of 1000 patients (34%) received analgesia. Postintervention data showed that 693 of 700 patients (99%) received analgesia, an absolute increase of 65% (95% CI 61%–68%), and that delay to analgesia administration fell from 69 (standard deviation [SD] 54) minutes to 35 (SD 43) minutes. Analgesics led to similar reductions in visual analog pain scale ratings during the pre- and postintervention phases (4.5 cm, SD 2.0 cm, and 4.3 cm, SD 3.0 cm, respectively).

Conclusion:

Our multifaceted ED pain management intervention was highly effective in improving quality of analgesia, timeliness of care and patient satisfaction. This protocol or similar ones have the potential to substantially improve pain management in diverse ED settings.
Acute myocardial infarction in patients with syncope
Authors: McDermott Daniel , Quinn James V. , Murphy Charles E.
Published: July 2016

Objective:

We sought to determine the incidence of acute myocardial infarction (AMI) in emergency department (ED) patients with syncope, the characteristics of these AMIs and how helpful the initial electrocardiogram (ECG) was in identifying these cases.

Methods:

In a prospective cohort of consecutive patients with syncope, the initial ECG was found to be abnormal using a prespecified definition (any nonsinus rhythm or any new or age-indeterminate abnormalities). Patients were then followed up to identify an AMI diagnosed within 30 days of presentation.

Results:

There were 1474 consecutive patient visits for syncope or near-syncope over a 45-month period spanning from Jul. 1, 2000, to Feb. 28, 2002, and Jul. 15, 2002, to Aug. 31, 2004, of which 46 (3.1%) were diagnosed with AMI. The majority of the AMI patients (42) had no ST segment elevation. The initial ECG was abnormal in 37 out of 46 cases. The diagnostic performance of the initial ECG was sensitivity 80% (95% confidence interval [CI] 67%–89%), specificity 64% (95% CI 61%–67%), negative predictive value 99% (95% CI 98%–100%), positive predictive value 7% (95% CI 6%–8%), positive likelihood ratio 2.2 (95% CI 1.6–2.5) and negative likelihood ratio 0.3 (95% CI 0.2–0.5).

Conclusion:

The incidence of AMI in patients presenting with syncope is low. A normal ECG has a high negative predictive value, although its sensitivity is limited.
Penetrating spinal cord injuries with retained canal fragments
Authors: Williams David T. , Chang Danny L. , DeClerck Matthieu P.
Published: July 2016

Case 1: A previously healthy 15-year-old boy was brought by paramedics to the emergency department (ED) after suffering multiple penetrating gunshot wounds (GSWs) to the lower extremities and a single entry to the left suprascapular region. Vital signs were within normal limits upon presentation.

Case 2: A previously healthy 19-year-old man was brought by paramedics to the ED after suffering multiple stab wounds to the back. The patient was hypoxic and in severe respiratory distress upon arrival. A left thoracostomy tube was placed. Clinically the patient improved and vital signs returned to normal.
Acute postpartum pulmonary edema in a 23-year-old woman 5 days after cesarean delivery
Authors: Dunne Caitlin , Meriano Antonio
Published: July 2016

The presentation of acute dyspnea after pregnancy is rare, but should bring a number of important conditions to the mind of the attending physician. Pulmonary embolism, amniotic fluid embolism, pneumonia, aspiration and pulmonary edema are some of the potentially devastating causes that must be considered. The percentage of pregnancies that are complicated by acute pulmonary edema has been estimated to be 0.08%. The most common contributing factors include the administration of tocolytic agents, underlying cardiac disease, iatrogenic fluid overload and preeclampsia. No matter what the underlying pathology, prompt administration of appropriate resuscitation is always the first priority. Only after the patient has been stabilized can attention be turned to diagnosis and specific treatment. This case examines one such presentation and reviews some of the diagnostic possibilities.
Chemical, biological, radiological and nuclear preparedness training for emergency medical services providers
Authors: Kollek Daniel , Welsford Michelle , Wanger Karen
Published: July 2016

Objective:

We assessed the self-reported theoretical and practical preparedness training of Canadian emergency medical services (EMS) providers in chemical, biological, radiological and nuclear (CBRN) events.

Methods:

We designed an online survey to address the theoretical and practical CBRN training level of prehospital providers. Emergency medical services staff in British Columbia and Ontario were invited to participate.

Results:

Of the 1028 respondents, 75% were male, and the largest demographic groups were front-line personnel with more than 15 years of experience. Only 63% of respondents indicated they had received either theoretical or practical training to work in a contaminated environment, leaving 37% who indicated they had received neither type of training. Of those that had received any training, 61% indicated they had received “hands-on” or practical training and 82% indicated they had received some training in identification of a possibly contaminated scene. Only 42% had received training for symptoms of nerve agents, 37% had received training for symptoms of blister agents and 46% had received training for symptoms of asphyxiants. Thirty-two percent had received training for the treatment of patients exposed to nerve agents, and 30% had received training for the treatment of patients exposed to blister agents. Only 31% of all respondents had received training for detecting radiation.

Conclusion:

CBRN events involve unique hazards and require specific education and training for EMS providers. A large proportion of Canadian EMS providers report not having received the training to identify and work in contaminated environments.
Effectiveness of a novel training program for emergency medicine residents in ultrasound-guided insertion of central venous catheters
Authors: Woo Michael Y. , Frank Jason , Lee A. Curtis , Thompson Calvin , Cardinal Pierre , Yeung Marianne , Beecker Jennifer
Published: July 2016

Objective:

Insertion of central venous catheters (CVCs) is an essential competency for emergency physicians. Ultrasound-guided (USG) insertion of CVCs has been shown to be safer than the traditional landmark technique. There is no clear consensus on effective methods for training physicians in USG insertion of CVCs. We developed and evaluated a novel educational training program in the USG technique for insertion of CVCs.

Methods:

Sixteen emergency medicine residents volunteered for a pre- and postprogram evaluation study, which was approved by our research ethics board. After their previous experience was determined, each participant was videotaped inserting a USG CVC in the right internal jugular vein on models. Participants then reviewed a Web-based instructional module and had a practical session. Participants were again videotaped inserting a USG CVC. The primary outcome was the change in score before and after the training program, using an expert-validated performance evaluation tool used to review the videotaped performances in a blinded fashion. Participants also completed a questionnaire to measure their satisfaction with the training program and any change in their perceived competence.

Results:

Participants ranged from residency year 1 to 5. Thirteen of 16 (81%) had never attempted USG insertion of a CVC. Participants reported that the models were realistic. Performance scores (12/19 to 13.2/19) and global ratings assessments (3.5/7 to 5.5/7) improved significantly (p < 0.01; the effect size, Cohen d = 1.12 before and 1.28 after) after the instruction. There was good interrater reliability between evaluators of the videotaped performances regarding performance scores (r = 0.68) and global rating scores (r = 0.75). All participants felt their confidence and technical skills were improved (p < 0.01) and all felt satisfied with the training program.

Conclusion:

This brief innovative multimethod training program was effective in enhancing emergency medicine resident competence in USG insertion of CVCs.
Diagnostic accuracy and clinical utility of emergency department targeted ultrasonography in the evaluation of first-trimester pelvic pain and bleeding: a systematic review
Authors: McRae Andrew , Edmonds Marcia , Murray Heather
Published: July 2016

Objective:

Emergency department targeted ultrasonography (EDTU) offers the possibility of rapid exclusion of ectopic pregnancy in patients with first-trimester pelvic pain or bleeding. We sought to systematically review the evidence describing the diagnostic accuracy and clinical utility of EDTU in the first trimester of pregnancy, and to generate a pooled estimate of the sensitivity and specificity of EDTU for the detection of intrauterine pregnancy (IUP).

Methods:

The literature search, abstract review and study selection were performed using predefined criteria. We abstracted the sensitivity and specificity of EDTU for IUP from included studies, and evaluated and summarized the evidence assessing the effect of EDTU use on time to diagnosis, time to treatment of ectopic pregnancy, emergency department (ED) length of stay and health care costs.

Results:

The specificity of EDTU for IUP in most studies exceeds 98%. The sensitivity in most studies exceeds 90%. Pooled estimates were not calculated because of statistical heterogeneity between studies. Published evidence indicates that EDTU use reduces the frequency of missed ectopic pregnancies, decreases time to surgery for ectopic pregnancy, shortens the length of stay for patients with normal pregnancies and may be more cost-effective than diagnostic strategies requiring formal ultrasonography.

Conclusion:

EDTU is highly specific for the identification of IUP. Patients who have an IUP identified with EDTU may be safely discharged from the ED with outpatient follow-up. The specificity of EDTU for IUP, along with the potential improvements in patient care that EDTU affords, justifies its adoption as routine ED care in evaluating first-trimester pain or bleeding.
The impact on patient flow after the integration of nurse practitioners and physician assistants in 6 Ontario emergency departments
Authors: Ducharme James , Alder Robert J. , Pelletier Cindy , Murray Don , Tepper Joshua
Published: July 2016

Objective:

We sought to assess the impact of the integration of the new roles of primary health care nurse practitioners (NPs) and physician assistants (PAs) on patient flow, wait times and proportions of patients who left without being seen in 6 Ontario emergency departments (EDs).

Methods:

We performed a retrospective review of health records data on patient arrival time, time of initial assessment by a physician, time of discharge from the ED and discharge status.

Results:

Whether a PA or NP was directly involved in the care of patients or indirectly involved by being on duty, the wait times, lengths of stay and proportion of patients who left without being seen were significantly reduced. When a PA or NP were directly involved in patients' care, patients were 1.6 (95% confidence interval [CI] 1.3–2.1,p< 0.05) and 2.1 (95% CI 1.6–2.8,p< 0.05) times more likely to be seen within the wait time benchmarks, respectively. Lengths of stay were 30.3% (95% CI 21.6%–39.0%,p< 0.01) and 48.8% (95% CI 35.0%–62.7%,p< 0.01) lower when PAs and NPs, respectively, were involved. When PAs and NPs were not on duty, the proportion of patients who left without being seen were 44% (95% CI 31%–63%,p< 0.01) and 71% (95% CI 53%–96%,p< 0.05), respectively.

Conclusion:

The addition of PAs or NPs to the ED team can improve patient flow in medium-sized community hospital EDs. Given the ongoing shortage of physicians, use of alternative health care providers should be considered. These results require validation, as their generalizability to other locations or types of EDs is not known.
Prehospital triage and direct transport of patients with ST-elevation myocardial infarction to primary percutaneous coronary intervention centres: a systematic review and meta-analysis
Authors: Brooks Steven C. , Allan Katherine S. , Welsford Michelle , Verbeek P. Richard , Arntz Hans-Richard , Morrison Laurie J.
Published: July 2016

Objective:

Percutaneous coronary intervention (PCI) appears to be superior to in-hospital fibrinolysis for most patients with ST-elevation myocardial infarction (STEMI). However, few hospitals have PCI capability. The optimal prehospital strategy for facilitating rapid coronary reperfusion in STEMI patients is unclear. We sought to determine whether direct transport of adult STEMI patients by emergency medical services to primary PCI centres improves 30-day all-cause mortality when compared with a strategy of transportation to the closest hospital.

Methods:

We systematically searched MEDLINE, EMBASE, Cochrane “CENTRAL” database (1980-July 2007) and several other electronic databases. Two authors independently assessed citations for relevance. Two authors independently abstracted data from included studies. We included studies that, 1) transported patients directly to a PCI-capable centre for primary PCI, 2) had a control group that was transported to the closest hospital and 3) reported outcomes of treatment time intervals, all-cause mortality, reinfarction rate, stroke rate or the frequency of cardiogenic shock. We used a random effects model to provide pooled estimates of relative risk (RR) when data allowed.

Results:

We identified 2264 citations with the search. Five studies, including 980 STEMI patients, met inclusion criteria, and were clinically heterogeneous and of variable quality. Most studies were European (3/5) and involved physician out-of-hospital care providers. There was a trend toward increased survival with direct transport to primary PCI but this was not statistically significant (RR 0.51, 95% confidence interval [CI] 0.24–1.10). One study reported nonsignificant reductions in reinfarction (RR 0.43, 95% CI 0.11–1.60) and stroke (RR 0.33, 95% CI 0.01–8.06) with direct transport for primary PCI.

Conclusion:

There is insufficient evidence to support the effectiveness of direct transport of patients with STEMI for primary PCI when compared with transportation to the closest hospital.
“I never hear what happens, even if they die”: a survey of emergency physicians about outcome feedback
Authors: Lavoie Curtis F. , Plint Amy C. , Clifford Tammy J. , Gaboury Isabelle
Published: July 2016

Objective:

Emergency physicians (EPs) rarely find out what happens to patients after the patients leave their care, a process we call “outcome feedback.” Some suggest this hinders the practice of emergency medicine (EM); however, evidence is lacking. We sought to evaluate EPs' perception of the current and potential role of outcome feedback in EM.

Methods:

We surveyed practising French- and English-speaking EPs from emergency departments within 100 km of Ottawa, Ont., in the provinces of Ontario and Quebec. The main outcomes included the prevalence, role and effect of outcome feedback.

Results:

Of the 297 physicians surveyed, 231 (77.8%) responded. The sample contained good representation of language groups, practice settings, sexes and age groups. All participants indicated that knowing outcomes is “essential” (62.6%) or “beneficial” (37.4%) to gaining experience in EM. Participants reported currently receiving passive outcome feedback in 10.0% of all cases, and seeking out (active) outcome feedback in 7.5% of all cases. The great majority of participants (97.3%) stated that they would like to receive more outcome feedback and believed that this would improve diagnostic accuracy (97.3%), clinical efficiency (85.5%), treatment outcomes (95.6%) and job satisfaction (95.1%). When asked to indicate “any possible negative effects that might arise from increased outcome feedback,” 62.1% indicated none. However, 17.9% hypothesized negative emotional effects and 11.5% suggested increased time requirements.

Conclusion:

The overwhelming majority of EPs receive very little outcome feedback. Most would like more outcome feedback and believe it would improve the practice of EM.
Simulation-based training in critical resuscitation procedures improves residents' competence
Authors: Langhan Trevor S. , Rigby Ian J. , Walker Ian W. , Howes Daniel , Donnon Tyrone , Lord Jason A.
Published: July 2016

Objective:

Residents must become proficient in a variety of procedures. The practice of learning procedural skills on patients has come under ethical scrutiny, giving rise to the concept of simulation-based medical education. Resident training in a simulated environment allows skill acquisition without compromising patient safety. We assessed the impact of a simulation-based procedural skills training course on residents' competence in the performance of critical resuscitation procedures.

Methods:

We solicited self-assessments of the knowledge and clinical skills required to perform resuscitation procedures from a cross-sectional multidisciplinary sample of 28 resident study participants. Participants were then exposed to an intensive 8-hour simulation-based training program, and asked to repeat the self-assessment questionnaires on completion of the course, and again 3 months later. We assessed the validity of the self-assessment questionnaire by evaluating participants' skills acquisition through an Objective Structured Clinical Examination station.

Results:

We found statistically significant improvements in participants' ratings of both knowledge and clinical skills during the 3 self-assessment periods (p< 0.001). The participants' year of postgraduate training influenced their self-assessment of knowledge (F2,25= 4.91,p< 0.01) and clinical skills (F2,25= 10.89,p< 0.001). At the 3-month follow-up, junior-level residents showed consistent improvement from their baseline scores, but had regressed from their posttraining measures. Senior-level residents continued to show further increases in their assessments of both clinical skills and knowledge beyond the simulation-based training course.

Conclusion:

Significant improvement in self-assessed theoretical knowledge and procedural skill competence for residents can be achieved through participation in a simulation-based resuscitation course. Gains in perceived competence appear to be stable over time, with senior learners gaining further confidence at the 3-month follow-up. Our findings support the benefits of simulation-based training for residents.
Does outcome feedback make you a better emergency physician? A systematic review and research framework proposal
Authors: Lavoie Curtis F. , Schachter Howard , Stewart Aviva T. , McGowan Jessie
Published: July 2016

Objective:

The organization of emergency medical care limits the ability of emergency physicians to know the outcomes of most of their patients after the patients leave the emergency department. This lack of outcome feedback may hinder the practice of emergency medicine (EM) by preventing “calibration” of the decision tools of practitioners. We sought to determine what is currently known about outcome feedback in EM, including its incidence, impact and modifiers.

Data source:

We searched the following databases: PreMED-LINE, MEDLINE, EMBASE, CINAHL, CENTRAL, PsycINFO, DARE, Health Technology Assessment Database and AMED. We performed manual searches on abstract databases, reference lists, various health information and research websites, and nonindexed journals.

Study selection:

Selection entailed a 2-step screening process to exclude articles not pertaining to outcome feedback in EM.

Data extraction:

Our search yielded 1128 bibliographic records, from which screening identified 7 relevant reports: 5 surveys, 1 system level evaluation and 1 intervention trial.

Data synthesis:

All studies were found to have “inadequate” or “unable to assess” reporting and study quality. Systems for outcome feedback to EM residents have been increasingly available since 1984, though they are perceived to be inadequate. Commonly used mechanisms for outcome feedback include automatic routing of discharge summaries, case conferences for admitted patients and telephone calls to patients or families for discharged patients. With respect to attending emergency physicians, no conclusions or clinical recommendations can be made given the level of available evidence.

Conclusion:

The potential importance of outcome feedback remains, at this time, underevaluated. We propose a research framework, and hypothesize that increasing outcome feedback would increase emergency physician diagnostic accuracy, therapeutic outcomes, clinical efficiency and job satisfaction. Future research in this area should include surveys and focus groups, as well as simulated or real-world intervention trials.
Understanding hospital and emergency department congestion: an examination of inpatient admission trends and bed resources
Authors: Wong Hannah J. , Morra Dante , Caesar Michael , Carter Michael W. , Abrams Howard
Published: July 2016

Objective:

Patients in the emergency department (ED) who have been admitted to hospital (inpatient “boarders”) are associated with ED overcrowding. They are also a symptom of a hospital-wide imbalance between demand and supply of resources. We analyzed the trends of inpatient admissions, ED boarding volumes, lengths of stay and bed resources of 3 major admitting services at our teaching institution.

Methods:

We used hospital databases from Jan. 1, 2004, to Dec. 31, 2007, to analyze ED visits that resulted in admission to hospital.

Results:

During the study period, 21 986 ED patients were admitted to hospital. The percentage of cancer-related admissions to the oncology admitting service decreased from 48% in 2004 to 24% in 2007, and admissions to general internal medicine (GIM) increased nearly 2-fold, from 28% in 2004 to 54% in 2007. In addition, GIM admitted about 10% more myocardial infarction and heart failure patients than did cardiology. General internal medicine constituted the majority of ED boarders and had a median boarding length of stay of approximately 15 hours. Inpatient beds on oncology and cardiology services remained static.

Conclusion:

Without bed capacity to admit more patients, our specialty services relied on GIM to serve as a safety net. At the same time, GIM was cited as a main source of ED congestion as their patients occupied more ED beds for longer periods than any other admitting service. The data presented in this study has helped effect positive change within our institution. Other hospitals running at or near capacity and faced with similar ED congestion may apply the methods we used in this study to analyze the cause and nature of their situation.
The effectiveness of training with an emergency department simulator on medical student performance in a simulated disaster
Authors: Franc-Law Jeffrey Michael , Ingrassia Pier Luigi , Ragazzoni Luca , Corte Francesco Della
Published: July 2016

Objective:

Training in practical aspects of disaster medicine is often impossible, and simulation may offer an educational opportunity superior to traditional didactic methods. We sought to determine whether exposure to an electronic simulation tool would improve the ability of medical students to manage a simulated disaster.

Methods:

We stratified 22 students by year of education and randomly assigned 50% from each category to form the intervention group, with the remaining 50% forming the control group. Both groups received the same didactic training sessions. The intervention group received additional disaster medicine training on a patient simulator (disastermed.ca), and the control group spent equal time on the simulator in a nondisaster setting. We compared markers of patient flow during a simulated disaster, including mean differences in time and number of patients to reach triage, bed assignment, patient assessment and disposition. In addition, we compared triage accuracy and scores on a structured command-and-control instrument. We collected data on the students' evaluations of the course for secondary purposes.

Results:

Participants in the intervention group triaged their patients more quickly than participants in the control group (mean difference 43 s, 99.5% confidence interval [CI] 12 to 75 s). The score of performance indicators on a standardized scale was also significantly higher in the intervention group (18/18) when compared with the control group (8/18) (p < 0.001). All students indicated that they preferred the simulation-based curriculum to a lecture-based curriculum. When asked to rate the exercise overall, both groups gave a median score of 8 on a 10-point modified Likert scale.

Conclusion:

Participation in an electronic disaster simulation using the disastermed.ca software package appears to increase the speed at which medical students triage simulated patients and increase their score on a structured command-and-control performance indicator instrument. Participants indicated that the simulation-based curriculum in disaster medicine is preferable to a lecture-based curriculum. Overall student satisfaction with the simulation-based curriculum was high.
Out-of-hospital cardiac arrest surveillance in Canada: a survey of national resources

Published: July 2016

Objective:

The general objective of this study was to explore the challenges of establishing an out-of-hospital cardiac arrest (OOHCA) surveillance program in Canada. More specifically, we attempted to determine the organizational structure of the delivery of emergency medical services (EMS) in Canada, describe the cardiac arrest data collection infrastructure in each province and determine which OOHCA variables are being collected.

Methods:

We conducted a national survey of 82 independent EMS health authorities in Canada. Methodology experts developed the survey and distribution using a modified Dillman technique. We distributed 67 surveys electronically (84%) and the rest by regular mail. We weighted each survey response by the population of the catchment area represented by the responding health authority (2004 census). Descriptive statistics are reported.

Results:

We received 60 completed surveys, representing a 73% response rate. The responding health authorities' catchment areas represented 80% of the Canadian population (territories excluded). Our survey results highlight a lack of common OOHCA data definitions used among health authorities, sporadic use of data quality assurance procedures, rare linkages to in-hospital survival outcomes and potential confidentiality issues. Other challenges raised by respondents included determining warehousing location and finding financial resources for a national OOHCA registry.

Conclusion:

Results from this survey demonstrate that, although it is challenging, it is possible to collect OOHCA data and access in-hospital survival outcomes. Collaborative efforts with the Resuscitation Outcomes Consortium and other potential provincial partners should be explored.
Door-to-antibiotic time for pneumonia in a rural emergency department
Authors: Anstett Danielle , Smallfield Audra , Vlahaki Dean , Milne W. Ken
Published: July 2016

Objective:

The Joint Commission on Accreditation of Healthcare Organizations recommends that patients admitted to hospital with pneumonia receive their first dose of antibiotics within 6 hours of presenting to the emergency department (ED). Previous research in the United States indicates that rural hospitals may be better at achieving this benchmark than urban centres. This particular quality indicator has not yet been evaluated in Canada. The purpose of this study was to determine whether the target door-to-antibiotic (DTA) time of 6 hours or less could be met in a rural ED.

Methods:

We conducted a retrospective chart review of patients admitted to hospital with a diagnosis of pneumonia. Descriptive data for each case was collected, including demographic and timeline information. We analyzed DTA time, antibiotic type, route of administration, hospital length of stay and disposition at discharge.

Results:

We reviewed a total of 320 charts from Apr. 1, 2003, to Mar. 31, 2008. The final sample consisted of 143 patients (50.3% women) whose median age was 79 years. The median DTA time was 151 minutes and 81.8% of patients received their first dose of antibiotics within 6 hours. Patients received antibiotics either orally (47.6%), intravenously (47.6%) or both (4.8%). Single-agent respiratory fluoroquinolones were used 71.4% of the time. Median length of hospital stay was 4 days; most patients were discharged home (79.7%), 11 died, 11 were transferred and 7 were discharged to a nursing home.

Conclusion:

A DTA time of 6 hours or less is achievable in a rural ED.

Published: July 2016

Objective:

Emergency medicine is an evolving discipline in Canadian medical schools. Little has been published regarding student preferences for emergency medicine training during the clerkship phase of MD programs. We assessed medical students' perceptions of a newly developed emergency medicine clerkship rotation involving multiple learning modalities. The evaluation process included assessment of the rotation's instructional elements and overall educational value.

Methods:

The first cohort of medical students to complete this new emergency medicine clerkship was invited to answer a questionnaire just before graduation. Students rated their preferences for components of the rotation using paired comparisons. Open-ended questions explored students' satisfaction with the emergency medicine clerkship as well as perceptions of the rotation's impact on career development.

Results:

Of the 94 students in the first clerkship cohort, 81 (86%) responded to the survey. Students found the emergency medicine clerkship highly valuable, citing the broad range of cases seen, close supervision, and opportunities to develop clinical assessment, decision-making and procedural skills. Students' curricular preferences were for advanced cardiac life support (ACLS) (26.4%), clinical shifts (20.6%), supervised clinical shifts (17.8%), procedural skills laboratories (14.8%), tutorials (10.8%) and preceptor-assisted learning sessions (9.8%).

Conclusion:

This new emergency medicine clerkship program incorporated multiple learning methods within a 4-week rotation and was highly rated by students. Although clinical shifts and ACLS were generally preferred activities, students had varying individual preferences for specific learning activities. Multiple learning methods allowed all students to benefit from the rotation. This study makes a compelling case for including an emergency medicine rotation with multiple learning modalities as a core element of clerkship at every medical school.
