Strategies for managing a busy emergency department
Authors: Campbell Samuel G. , Sinclair Douglas E. ,   The Canadian Association of Emergency Physicians Flow Management contributors
Published: July 2016

ABSTRACTIn a time of increased patient loads and emergency department (ED) exit block, the need for strategies to manage patient flow in the ED has become increasingly important. In March 2002 we contacted all 1282 members of the Canadian Association of Emergency Physicians and asked them to delineate strategies for enhancing ED patient flow and ED productivity without increasing stress levels, reducing care standards or compromising patient safety. Thirty physicians responded. Their suggested flow management strategies, which ranged from clinical decision-making to communication to choreography of time, space and personnel, are summarized here.
Lemierre syndrome in a child with recent pharyngitis
Authors: Busko Jonnathan Moore , Triner Wayne 
Published: July 2016

ABSTRACTA 14-year-old boy presented with fever and progressive respiratory distress, one week after an episode of pharyngitis. Although there was a concern about pulmonary embolism secondary to a lower extremity fracture, his presentation was most consistent with Lemierre syndrome. This syndrome is an uncommon but potentially lethal complication of otolaryngological infections. Early recognition and aggressive antibiotic therapy are critical elements in reducing mortality. Emergency physicians should be aware of this syndrome because its incidence appears to be increasing.

Published: July 2016

ABSTRACTObjective:Self-inflicted injury is commonly seen in emergency departments (EDs). It may be a precursor to death by suicide. The objective of this study was to examine the epidemiology of self-inflicted injury presentations to EDs in the province of Alberta.Methods:Self-inflicted injury records for the 3 fiscal years 1998/99 to 2000/01 were accessed from the Ambulatory Care Classification System, a database that captures all ED encounters in the province of Alberta. Available data for each case included demographic details, location and time of visit, diagnoses and procedures.Results:There were 22 396 self-inflicted injury presentations to Alberta EDs during the study period. Self-inflicted injury rates were higher in females, younger patients, those on social services and those with Aboriginal treaty status. There were higher rates of return visits in the year following the self-inflicted injury than in other patient groups. Data showed regional variation. Trends could be seen in the timing of self-inflicted injury presentations by hour of day, day of week, and month of year.Conclusions:Self-inflicted injury is common, with particularly high rates demonstrated among marginalized populations. This study provides comprehensive data on those who present with self-inflicted injuries, and can be used to guide further treatment, research and evaluation for this population.
Compliance with guidelines for emergency management of asthma in adults: experience at a tertiary care teaching hospital
Authors: Krym Valerie F. , Crawford Brent , MacDonald Russell D. 
Published: July 2016

ABSTRACTObjectives:Despite evidence-based clinical practice guidelines for the emergency management of asthma, substantial treatment variation exists. Our objective was to assess compliance with the Canadian Association of Emergency Physicians (CAEP) / Canadian Thoracic Society (CTS) Asthma Advisory Committee’s “Guidelines for the emergency management of asthma in adults” in the emergency department (ED) of a university-affiliated tertiary care teaching hospital.Methods:This retrospective study was conducted in a Canadian inner city adult ED. Investigators reviewed all ED records for the period from Jan. 1, 2001, to Dec. 31, 2001, and identified adult patients (i.e., &gt;18 years of age) with a primary ED diagnosis of asthma. Hospital records were then reviewed to document compliance with the CAEP/CTS asthma guidelines. Descriptive statistics, including means, standard deviations and frequencies were used to summarize information.Results:Overall compliance with the guidelines was 69.6%, (95% confidence interval, 64.7%–74.5%), but compliance ranged from 41.4% for severe asthma, 67.1% for moderate asthma, and 88.6% for mild asthma. Interobserver reliability for compliance assessment was excellent.Conclusions:Despite publication and dissemination of evidence-based guidelines for the management of acute asthma in adults, guideline compliance at a university-affiliated, inner city, tertiary care teaching hospital ED is suboptimal.
Intravenous magnesium for acute benign headache in the emergency department: a randomized double-blind placebo-controlled trial
Authors: Frank Leonard R. , Olson Carin M. , Shuler Klaus B. , Gharib Salma F. 
Published: July 2016

ABSTRACT

Background:
Magnesium deficiency may play a role in the pathogenesis of migraines and other headaches. Studies in outpatient clinics have found that magnesium administered intravenously (IV) reduces headache pain. We investigated the effectiveness of IV magnesium in patients with acute benign headache who presented to the emergency department (ED).

Methods:
This randomized double-blind placebo-controlled trial compared 2 g of IV magnesium versus placebo for the treatment of patients with acute benign headache who presented to the EDs of two teaching hospitals. Pre- and post-treatment pain scores were measured on a 100-mm visual analog pain scale.

Results:
Forty-two patients were randomized, 21 in each treatment group. Treatment groups had similar baseline characteristics. After treatment, placebo recipients reported an 8-mm median improvement in pain, and magnesium recipients had a 3-mm improvement (p = 0.63). We found no statistically significant difference between groups for any secondary outcomes; however, the patients who received magnesium had significantly (p = 0.03) more side effects than did those in the placebo group.

Conclusions:
We found no benefit to using IV magnesium to treat patients with acute benign headache who present to the ED.
Test characteristics of neuroimaging in the emergency department evaluation of children for cerebrospinal fluid shunt malfunction
Authors: Mater Ahmed , Shroff Manohar , Al-Farsi Sami , Drake James , Goldman Ran D. 
Published: July 2016

ABSTRACT

Objective:
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.

Methods:
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.

Results:
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.

Conclusion:
Neuroimaging has a low sensitivity for identifying shunt malfunction. Neurosurgical consultation should be sought if shunt malfunction is clinically suspected, despite normal imaging.
Safety of a modification of the triage level for febrile children 6 to 36 months old using the Paediatric Canadian Triage and Acuity Scale
Authors: Gravel Jocelyn , Manzano Sergio , Arsenault Michael 
Published: July 2016

ABSTRACT

Objective:
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.

Methods:
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).

Results:
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 &lt; 0.001). No down-triaged patient died or required ICU admission.

Conclusion:
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.
Patient and family–centred care for pediatric patients in the emergency department
Authors: Brown Kathleen , Mace Sharon E. , Dietrich Ann M. , Knazik Stephen , Schamban Neil E. 
Published: July 2016

ABSTRACTPatient and family–centred care (PFCC) is an approach to health care that recognizes the integral role of the family and encourages mutually beneficial collaboration between the patient, family and health care professionals. Specific to the pediatric population, the literature indicates that the majority of families wish to be present for all aspects of their child's care and be involved in medical decision-making. Families who are provided with PFCC are more satisfied with their care. Integration of these processes is an essential component of quality care. This article reviews the principles of PFCC and their applicability to the pediatric patient in the emergency department; and it discusses a model for integrating PFCC that is modifiable based on existing resources.
Substance-related problems in patients visiting an urban Canadian emergency department

Published: July 2016

ABSTRACTObjective:For many patients with addiction and other substance problems, the emergency department (ED) is the sole provider of medical care. This study sought to determine the prevalence and characteristics of substance-related medical problems in ED patients, as defined by documentation in the medical record. We also sought to compare the ED resource use (length of ED stay and number of revisits) of patients with and without substance problems.Methods:Trained evaluators using explicit criteria reviewed all ED charts during a 6-week period at a Canadian tertiary care teaching centre. Data was collected on demographics, documentation of problematic substance use and whether the ED visit was due to substance problems. Using a computerized database, we determined how many patients with and without substance problems had 1 or more subsequent ED visits during the 1-year period from Sept. 1, 2002, to Aug. 31, 2003.Results:Of 6064 visits made by 5194 patients, 6026 visits (99.4%) representing 5188 patients (99.9%) were captured for review. Of those visits, 674 (11.2%, 95% confidence interval [CI] 10.4%–12.0%), made by 600 patients, had documentation of problematic substance use and 521 visits (8.6%, 95% CI 7.9%–9.4%) by 469 patients were caused by substance problems. The mean age of patients with a visit due to a substance problem was 39.2 years, compared with 48.5 years for those with other visits (p&lt; 0.001). The admission rate for substance-related visits was 25.3%, compared with 17.6% for other visits (p&lt; 0.001). For discharged patients, the median length of the ED visit owing to substance-related problems lasted 232 minutes (IQR [interquartile range] 267 min), compared with 164 minutes (IQR 167 min) for other visits (p&lt; 0.001). In 1 year of follow-up, 161 of 600 patients (26.8%) with a substance problem made 466 revisits (mean 0.78 revisits/patient), compared with 975 of 4588 patients (21.3%) without a substance problem who made a total of 2150 revisits (mean 0.47 revisits/patient,p&lt; 0.001).Conclusion:Substance problems contribute significantly to ED visits, hospital admissions and duration of ED stay at a tertiary centre. It is likely that our methodology underestimates the scope of the problem and that a universal screening program would find a higher prevalence. The magnitude of this problem supports the need for an interdisciplinary identification and intervention program for ED patients with substance-related issues.
Ruptured abdominal aortic aneurysm masquerading as isolated hip pain: an unusual presentation
Authors: Vaidyanathan Sriram , Wadhawan Himanshu , Welch Pedro , El-Salamani Murad 
Published: July 2016

ABSTRACT
The rupture of an abdominal aortic aneurysm (AAA) is a catastrophic event. Misdiagnosis by first-contact emergency physicians remains a serious concern. Varied and frequently nonspecific presentations lead to erroneous diagnostic impressions and cause significant delays in definitive intervention. We report the case of a 73-year-old man with a ruptured AAA presenting with isolated acute right hip pain without any classical features such as truncal pain or hypotension. Despite major advances in imaging and definitive treatment, a heightened awareness among emergency physicians remains the only effective means of improving detection and thereby survival.
Introducing a nurse practitioner into an urban Canadian emergency department

Published: July 2016

ABSTRACTObjective:Our objective was to compare the emergency care provided by a nurse practitioner (NP) with that provided by emergency physicians (EPs), to identify emergency department (ED) patients appropriate for autonomous NP practice and to acquire data to facilitate the development of the clinical scope of practice recommendations for ED practice for NPs.Methods:Using a comprehensive 3-part process, we selected and hired the best NP from 12 applicants. The NP was oriented to the operations of our free-standing community ED and incorporated in the care team, working in real time with EP preceptors during a 6-month, prospective clinical assessment comparing NP care with EP care. ED preceptors reviewed every case in real time with the NP and completed an explicit evaluation form to determine whether NP assessment, investigation, treatment and disposition were “all equivalent to emergency physician care” (AEEPC) or whether they differed. The proportion of AEEPC interactions was determined for 23 patient presentation categories. Our a priori assumption was that a patient presentation category might be suitable for autonomous NP practice if 50% of NP encounters in that category were rated as AEEPC. Descriptive data were presented for patient case mix, teaching domains and time criteria.Results:Eighty-three NP shifts and 711 patient encounters were evaluated by 21 EP preceptors. The NP saw a median of 8 patients per shift. In 43% of encounters, NP care was AEEPC. Highest AEEPC rates were found in the patient follow-up categories general follow-up (55.4%), diagnostic imaging (91.7%) and microbiology laboratory results (87.6%). NP scores over 50% were also seen for lacerations (63.6%) and isolated sore throats (53%). With teaching, NP performance improved over time.Conclusion:With the exception of follow up–related complaints, simple lacerations and isolated sore throats, NP care differed substantially from EP care. Although NPs with extensive emergency experience and training might ultimately be able to function as autonomous ED care providers, Canadian EDs currently developing job descriptions for emergency NPs should focus on a model of collaborative practice with EPs.
Errors, near misses and adverse events in the emergency department: What can patients tell us?
Authors: Friedman Steven M. , Provan David , Moore Shannon , Hanneman Kate 
Published: July 2016

ABSTRACTObjective:We sought to determine whether patients or their families could identify adverse events in the emergency department (ED), to characterize patient reports of errors and to compare patient reports to events recorded by health care providers.Methods:This was a prospective cohort study in a quaternary care inner city teaching hospital with approximately 40 000 annual visits. ED patients were recruited for participation in a standardized interview within 24 hours of ED discharge and a follow-up interview 3–7 days after discharge. Responses regarding events were tabulated and compared with physician and nurse notations in the medical record and hospital event reporting system.Results:Of 292 eligible patients, 201 (69%) were interviewed within 24 hours of ED discharge, and 143 (71% of interviewees) underwent a follow-up interview 3–7 days after discharge. Interviewees did not differ from the base ED population in terms of age, sex or language. Analysis of patient interviews identified 10 adverse events (5% incident rate; 95% confidence interval [CI] 2.41%–8.96%), 8 near misses (4% incident rate; 95% CI 1.73%–7.69%) and no medical errors. Of the 10 adverse events, 6 (60%) were characterized as preventable (2 raters; κ = 0.78, standard error [SE] 0.20; 95% CI 0.39–1.00;p= 0.01). Adverse events were primarily related to delayed or inadequate analgesia. Only 4 out of 8 (50%) near misses were intercepted by hospital personnel. The secondary interview elicited 2 out of 10 adverse events and 3 out of 8 near misses that had not been identified in the primary interview. No designation (0 out of 10) of an adverse event was recorded in the ED medical record or in the confidential hospital event reporting system.Conclusion:ED patients can identify adverse events affecting their care. Moreover, many of these events are not recorded in the medical record. Engaging patients and their family members in identification of errors may enhance patient safety.
Canadian Association of Emergency Physicians Sepsis Guidelines: the optimal management of severe sepsis in Canadian emergency departments

Published: July 2016

ABSTRACT

Introduction:
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.

Methods:
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.

Results:
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.

Conclusion:
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.
Left vertebral artery dissection causing bilateral internuclear ophthalmoplegia

Published: July 2016

ABSTRACTA 21-year-old woman presented to the emergency department 1 day after a fall. On the day of presentation, she awoke with horizontal diplopia and posterior neck pain. Based on clinical findings, she was diagnosed with bilateral internuclear ophthalmoplegia. A conventional angiogram identified a left vertebral artery dissection. She was started on anticoagulant therapy, with gradual improvement of her diplopia over several months. Diplopia is frequently seen in the emergency department. Internuclear ophthalmoplegia is a cause of binocular diplopia and is important to recognize because it indicates a brainstem lesion requiring neurologic evaluation.
Central diabetes insipidus misdiagnosed as acute gastroenteritis in a pediatric patient

Published: July 2016

ABSTRACT
This case report describes an unusual presentation of nausea, vomiting and diarrhea, which was misdiagnosed as acute gastroenteritis in a 6-year-old girl. The patient later returned to the emergency department (ED) with severe dehydration from idiopathic central diabetes insipidus (DI). At her first visit, this previously healthy patient presented with mild dehydration, signs of acute gastroenteritis and normal urine output. Her brother had experienced similar symptoms a few days earlier. She tolerated an oral fluid challenge and was discharged from the ED with stable vital signs. Two days later, the patient returned with severe dehydration, resolving diarrhea and persistent vomiting. She was admitted to the pediatric intensive care unit. Magnetic resonance imaging illustrated an absent posterior pituitary enhancing signal, which demonstrated a loss of function in that region. There were no other abnormalities. The patient subsequently received desmopressin with improving clinical status and was discharged on the eighth hospital day. DI is a rare disease, but can be fatal if left undiagnosed. It should, therefore, be considered in the differential diagnosis of a dehydrated patient with an unexpectedly low urine specific gravity.
