ABSTRACT:Objective:There are few reports in the medical literature describing removal of a coin from the upper esophageal tract of a child by an emergency physician. However, given the nature of their training and practice, emergency physicians are well suited to perform this common procedure. We describe our experience with this procedure.Methods:This was a retrospective review of a continuous quality improvement data set from a university-based tertiary care pediatric emergency department between Nov. 1, 2003, and Mar. 31, 2004.Results:Thirteen children, with a median age of 20 months, underwent rapid sequence intubation and had coins successfully removed from their upper esophageal tract by emergency physicians. In 10 cases, the coin was visible at laryngoscopy and removed with Magill forceps. In 3 cases this approach failed and a Foley catheter was used to remove the coin. One child suffered a tonsillar abrasion and two sustained minor lip trauma, but all were extubated and discharged home from the emergency department with no significant complications. Eleven of the 13 patients were successfully followed up, and the parents reported no problems.Conclusions:This pilot study suggests that the removal of a coin from the upper esophageal tract by an emergency physician can be both safe and effective. A larger study is needed before this procedure can be generally recommended.
Bicarbonate therapy for unstable propafenone-induced wide complex tachycardia
Authors: Brubacher Jeff 
Published: July 2016

ABSTRACTA previously healthy 73-year-old woman presented to hospital with acute atrial fibrillation. After intravenous procainamide failed to restore sinus rhythm, she was treated with 300 mg of oral propafenone and discharged with a prescription for propafenone and propranolol. Six hours later she took 150 mg of propafenone as prescribed. Within 1 hour she became dyspneic and collapsed. On arrival in hospital she was unconscious, with a wide complex tachycardia and no obtainable blood pressure. After defibrillation and lidocaine, she converted to a wide complex sinus rhythm, but remained profoundly hypotensive despite intravenous epinephrine and dopamine. Hypertonic sodium bicarbonate (HCO3) was administered and, shortly thereafter, her blood pressure increased, her QRS duration normalized and her clinical status improved dramatically. In this case of severe refractory propafenone-related cardiac toxicity, intravenous HCO3led to a profound clinical improvement. Emergency physicians should be familiar with the syndrome of sodium-channel blocker poisoning and recognize the potentially important role of bicarbonate in its treatment.
The use of induced hypothermia after cardiac arrest: a survey of Canadian emergency physicians
Authors: Kennedy Joel , Green Robert S. , Stenstrom Robert ,   on behalf of the CAEP Critical Care Committee
Published: July 2016

ABSTRACTObjective: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.Methods: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.Results: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.Conclusion: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.
Bilateral pneumothoraces and pneumomediastinum complicating a generalized tonic-clonic seizure
Authors: Curran Helen , Ross John 
Published: July 2016

ABSTRACTPatients often present to the emergency department following a generalized tonic-clonic seizure, particularly of new onset. Complications associated with seizures usually arise from injuries sustained from loss of consciousness or during convulsive activity. This report describes a patient with an idiopathic seizure who developed postictal alveolar edema and delayed bilateral pneumothoraces and pneumomediastinum. A literature search revealed only 1 other case of this potentially life-threatening pulmonary complication from seizures.
Clinical outcomes and patient satisfaction of a pharmacist-managed, emergency department–based outpatient treatment program for venous thromboembolic disease
Authors: Zed Peter J. , Filiatrault Lyne 
Published: July 2016

ABSTRACTObjective:The purpose of this study was to evaluate the efficacy, safety and patient satisfaction outcomes of our pharmacist-managed, emergency department (ED)–based outpatient treatment program for venous thromboembolism (VTE) disease.Methods:We conducted a prospective cohort study of all patients who were enrolled in the Vancouver General Hospital (VGH) outpatient VTE treatment program over a 7-year period (1999–2006). Efficacy outcomes include recurrent VTE events at 3 and 6 months following discharge from the program. Safety evaluation included major and minor bleeding complications and the development of thrombocytopenia during the acute phase of therapy. Patient satisfaction was assessed using an 18-question patient satisfaction survey, which was mailed to all patients following discharge from the program.Results:Overall, 305 patients were included in the study. Of the 260 evaluable patients, 2 patients (0.8%, 95% confidence interval [CI] 0.2–2.7) experienced a recurrent VTE at 3 months and 5 patients (1.9%, 95% CI 0.8–4.4) had a recurrence at 6 months. One patient (0.3%, 95% CI 0.1–1.8) experienced a major bleeding complication. Seven patients (2.3%, 95% CI 1.1–4.7) experienced a minor bleeding complication and no patient developed thrombocytopenia. Overall, 96.1% were comfortable having their condition treated as an outpatient and 85.7% felt it was more convenient to return to hospital daily for medications and assessment than to be admitted to hospital. Finally, 96.9% of respondents were very satisfied or satisfied with the treatment they received in the outpatient program, and 96.1% would enroll again if future treatment was indicated.Conclusion:Our pharmacist-managed, ED-based outpatient treatment program for VTE disease is safe, effective and achieves a high level of patient satisfaction.
Can Telehealth Ontario respiratory call volume be used as a proxy for emergency department respiratory visit surveillance by public health?
Authors: van Dijk Adam , McGuinness Don , Rolland Elizabeth , Moore Kieran M. 
Published: July 2016

ABSTRACTObjective:There is a paucity of information regarding the usefulness of non-traditional data streams for real-time syndromic surveillance systems. The objective of this paper is to examine the temporal relation between Ontario's emergency department (ED) visits and telephone health line (Telehealth) call volume for respiratory illnesses to test the feasibility of using Ontario's Telehealth system for real-time surveillance.Methods:Retrospective time-series data from the National Ambulatory Care Reporting System (NACRS) and the Telehealth Ontario program from June 1, 2004, to March 31, 2006, were analyzed. The added value of Telehealth Ontario data was determined by comparing it temporally with NACRS data, which uses the International Classification of Diseases (ICD) 10-Canadian Enhancement coding system for discharge diagnoses.Results:Telehealth Ontario had 216 105 calls for respiratory complaints, while 819 832 ICD-coded complaints from NACRS were identified with a comparable diagnosis of respiratory illness. Telehealth Ontario call volume was heavily weighted for the 0–4 years age group (49%), while the NACRS visits were mainly from those 18–64 years old (44%). The Spearman rank correlation coefficient was calculated to be 0.97, with the time-series analysis also resulting in significant correlations at lags (semi-monthly) 0 and 1, indicating that increases in Telehealth Ontario call volume correlate with increases in NACRS discharge diagnosis data for respiratory illnesses.Conclusion:Telehealth Ontario call volume fluctuation reflects directly on ED respiratory visit data on a provincial basis. These call complaints are a timely, useful and representative data stream that shows promise for integration into a real-time syndromic surveillance system.
Rural emergency department use by CTAS IV and V patients
Authors: Steele Sandra , Anstett Danielle , Milne W. Ken 
Published: July 2016

ABSTRACTObjective: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.Methods: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.Results: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.Conclusion: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.
The “delay effect” of donning a gown during cardiopulmonary resuscitation in a simulation model
Authors: Watson Leah , Sault William , Gwyn Randy , Verbeek P. Richard 
Published: July 2016

ABSTRACT

Objective:
We sought to determine whether the use of currently issued gowns delays initiation of chest compressions and ventilations during cardiopulmonary resuscitation and whether simple gown modifications can reduce this delay.

Methods:
Firefighter defibrillation instructors were allocated into pairs and videotaped while performing standardized cardiac arrest scenarios. Three scenarios were compared: “no gown,” “standard gown” and “modified gown.” Key time intervals were extracted from videotaped data.

Results:
Ninety-five scenarios were analyzed. Mean time interval to chest compression was 39 seconds (95% confidence interval [CI] 34–43) for “no gown” scenarios, 71 seconds (95% CI 66–77) for “standard gown” scenarios and 59 seconds (95% CI 54–63) for “modified gown” scenarios (p &lt; 0.001). Time to first ventilation was 146 seconds (95% CI 134–158), 238 seconds (95% CI 224–253)and 210 seconds (95% CI 198–223) in the 3 groups, respectively (p &lt; 0.001). Post hoc testing showed that the time differences between all groups were statistically significant.

Conclusion:
Standard gowns protect front-line care providers but cause significant delays to chest compressions and ventilations, potentially increasing patient morbidity and mortality. Minor gown modifications, including pre-tied neck straps and longer waist ties that tie in front, allow for easier use and shorter delays to time-critical interventions. Future research is required to reduce care delays while maintaining adequate protection of emergency medical service providers from infectious disease.

Published: July 2016

ABSTRACTObjective:We sought to determine the diagnostic accuracy of clinical prediction rules to exclude acute coronary syndrome (ACS) in the emergency department (ED) setting.Methods:We searched MEDLINE, EMBASE, Web of Science and the Cochrane Database of Systematic Reviews. We contacted content experts to identify additional articles for review. Reference lists of included studies were hand searched. We selected articles for review based on the following criteria: 1) enrolled consecutive ED patients; 2) incorporated variables from the history or physical examination, electrocardiogram and cardiac biomarkers; 3) did not incorporate cardiac stress testing or coronary angiography into prediction rule; 4) based on original research; 5) prospectively derived or validated; 6) did not require use of a computer; and 7) reported sufficient data to construct a 2 ∞ 2 contingency table. We assessed study quality and extracted data independently and in duplicate using a standardized data extraction form.Results:Eight studies met inclusion criteria, encompassing 7937 patients. None of the studies verified the prediction rule with a reference standard on all or a random sample of patients. Six studies did not report blinding prediction rule assessors to reference standard results, and vice versa. Three prediction rules were prospectively validated. Sensitivities and specificities ranged from 94% to 100% and 13% to 57%, and positive and negative likelihood ratios from 1.1 to 2.2 and 0.01 to 0.17, respectively.Conclusion:Current prediction rules for ACS have substantial methodological limitations and have not been successfully implemented in the clinical setting. Future methodologically sound studies are needed to guide clinical practice.
ALaRMED: adverse events in low-risk chest pain patients receiving continuous ECG monitoring in the emergency department: a survey of Canadian emergency physicians
Authors: Atzema Clare L. , Schull Michael J. 
Published: July 2016

ABSTRACT

Objective:
Current guidelines suggest that most patients who present to an emergency department (ED) with chest pain should be placed on a continuous electrocardiographic monitoring (CEM) device. We surveyed emergency physicians to determine their perception of current occupancy rates of CEM and to assess their attitudes toward prescribing monitors for low-risk chest pain patients in the ED.

Methods:
We conducted a cross-sectional, self-administered Internet and mail survey of a random sample of 300 members of the Canadian Association of Emergency Physicians. Main outcome measures included the perceived frequency of fully occupied monitors in the ED and physicians' willingness to forgo CEM in certain chest pain patients.

Results:
The response rate was 66% (199 respondents). The largest group of respondents (43%; 95% confidence interval [CI] 36%–50%) indicated that monitors were fully occupied 90%–100% of the time during their most recent ED shift. When asked how often they were forced to choose a patient for monitor removal because of the limited number of monitors, 52% (95% CI 45%–60%) of respondents selected 1–3 times per shift. Ninety percent (95% CI 84%–93%) of respondents indicated that they would forgo CEM in certain cardiac chest pain patients if there was good evidence that the risk of a monitor-detected adverse event was very low.

Conclusion:
Emergency physicians report that monitors are often fully occupied in Canadian EDs, and most are willing to forgo CEM in certain chest pain patients. A large prospective study of CEM in low-risk chest pain patients is warranted.
A door-to-needle time of 30 minutes or less for myocardial infarction thrombolysis is possible in rural emergency departments
Authors: Vlahaki Dean , Fiaani Majed , Milne William Ken 
Published: July 2016

ABSTRACTObjective:The Canadian Emergency Cardiac Care Coalition, the American Heart Association and similar groups have established a benchmark for the administration of thrombolytics in acute myocardial infarction (AMI) care as a door-to-needle (DTN) time of 30 minutes or less. Previous research suggests that this goal is not being achieved in Canada. The purpose of this study was to determine whether the target DTN time of 30 minutes or less for thrombolysis could be met in 2 rural Ontario emergency departments (EDs).Methods:We conducted a retrospective chart review and obtained descriptive data for each case, including demographic information and the Canadian Emergency Department Triage and Acuity Scale (CTAS) score. Visit timeline data were also collected and included the time during which patients saw a physician, had an electrocardiogram (ECG), received thrombolytic therapy and were discharged from the ED. Relevant time intervals, such as the median DTN time, were calculated.Results:A total of 454 charts were reviewed for patients with a diagnosis of AMI who were seen between 1996 and 2007. The final sample consisted of 101 patients who received thrombolytics (63% men) whose median age was 67 years and median CTAS score was Level II (Emergent). The median door-to-ECG time was 6 minutes, door-to-physician time was 8 minutes and DTN time was 27 minutes; 58% of patients received thrombolytics within 30 minutes.Conclusion:A DTN time of 30 minutes or less is achievable in rural EDs.
Pediatric myth: fever and petechiae
Authors: Klinkhammer Martin D. , Colletti James E. 
Published: July 2016

ABSTRACTA child presenting with petechiae and fever is assumed to have meningococcemia or another form of bacterial sepsis and therefore to require antibiotics, blood cultures, cerebrospinal fluid analysis and hospital admission. A review of the literature challenges this statement and suggests that a child presenting with purpura (or petechiae), an ill appearance and delayed capillary refill time or hypotension should be admitted and treated for meningococcal disease without delay. Conversely, a child with a petechial rash, which is confined to the distribution of the superior vena cava, is unlikely to have meningococcal disease. Outpatient therapy in this context is appropriate. In other children, a reasonable approach would be to draw blood for culture and C-reactive protein (CRP) while administering antibiotics. If the CRP is normal, these children could be discharged to follow-up in 1 day, whereas children with CRP values greater than 6 mg/L would be admitted.
Impact of a rapid access protocol on decreasing door-to-balloon time in acute ST elevation myocardial infarction
Authors: Caudle Jaelyn M. , Piggott Zoe , Dostaler Suzanne , Graham Karen , Brison Robert J. 
Published: July 2016

ABSTRACT

Objective:
Ischemic cardiovascular disease is the leading cause of death in Canada. In ST elevation myocardial infarction (STEMI), time to reperfusion is a key determinant in reducing morbidity and mortality with percutaneous coronary intervention (PCI) being the preferred reperfusion strategy. Where PCI is available, delays to definitive care include times to electrocardiogram (ECG) diagnosis and cardiovascular laboratory access. In 2004, the Cardiac Care Network of Ontario recommended implementation of an emergency department (ED) protocol to reduce reperfusion time by transporting patients with STEMI directly to the nearest catheterization laboratory. The model was implemented in Frontenac County in April 2005. The objective of this study was to assess the effectiveness of a protocol for rapid access to PCI in reducing door-to-balloon times in STEMI.

Methods:
Two 1-year periods before and after implementation of a rapid access to PCI protocol (ending March 2005 and June 2006, respectively) were studied. Administrative databases were used to identify all subjects with STEMI who were transported by regional emergency medical services (EMS) and received emergent PCI. The primary outcome measure was time from ED arrival to first balloon inflation (door-to-balloon time). Times are presented as medians and interquartile ranges (IQRs). Statistical comparisons were made using the Mann–Whitney U test and presented graphically with Kaplan–Meier curves.

Results:
Patients transported under the rapid access protocol (n = 39) were compared with historical controls (n = 42). Median door-to-balloon time was reduced from 87 minutes (IQR 67–108) preprotocol to 62 minutes (IQR 40–80) postprotocol (p &lt; 0.001).

Conclusion:
In our region, implementation of an EMS protocol for rapid access to PCI significantly reduced time to reperfusion for patients with STEMI.
A prospective study of students’ and instructors’ opinions on Advanced Cardiac Life Support course teaching methods
Authors: Stempien James , Betz Martin 
Published: July 2016

ABSTRACT

Introduction:
The American Heart Association (AHA) revises the Advanced Cardiac Life Support (ACLS) course approximately every 5 years, citing the scientific literature for any changes to content and management recommendations. With ACLS 2005, the AHA also revised the methods used to teach course content. The AHA cited no evidence in making these changes. The ACLS 2005 course, distributed in early 2007, makes greater use of videos to teach students. This prospective study surveyed opinions of both students and instructors in an effort to determine the level of satisfaction with this method of teaching.

Methods:
During 16 consecutive ACLS courses, all students and instructors were asked to complete a questionnaire. The students provided demographic information, but completed the survey anonymously. Four questions probed the participants' opinions about the effectiveness of videos in learning ACLS skills. Experienced participants were asked to compare the new teaching methods with previous courses. Opinions were compared among several subgroups based on sex, occupation and previous experience.

Results:
Of the 180 students who participated, 71% felt the videos were unequivocally useful for teaching ACLS skills. Fewer first-time students were unequivocally positive (59%) compared with those who had taken 2 or more previous courses (84%). A small proportion of students (13%) desired more hands-on practice time. Of the 16 instructors who participated, 31% felt that the videos were useful for teaching ACLS skills. No differences were found between doctors and nurses, or between men and women.

Conclusion:
The use of standardized videos in ACLS courses was felt by the majority of students and a minority of instructors to be unequivocally useful. First-time students had more doubts about the effectiveness of videos.
