LO098: Education innovation: implementing a point-of-care ultrasound curriculum for emergency medicine residents
Authors: Leung D. , Chenkin J.
Published: June 2016

Introduction / Innovation Concept: Point-of-care ultrasound (POCUS) is becoming standard of care in Canadian emergency departments. However, its integration in Emergency Medicine (EM) residency training is poorly studied. If a four-week curriculum can successfully teach POCUS skills to residents, this program could have potential application across specialties and across Canada. Methods: A four-week curriculum was designed, implemented, and evaluated. EM residents registered for the Introductory Ultrasound Rotation at Sunnybrook Health Sciences Centre were invited to participate. Curriculum evaluation included resident feedback, pre-rotation and post-rotation knowledge and skill testing, and a delayed post-rotation survey. Comparison of pre-test and post-test scores were calculated using the paired t-test. Curriculum, Tool, or Material: Residents were scheduled for both dedicated ultrasound scanning shifts and clinical shifts with an emphasis on POCUS in patient care. Residents also reviewed the Canadian Emergency Ultrasound Society Emergency Department Echo DVD and manual, completed weekly readings and assignments, and completed a “clinical encounter worksheet” describing how POCUS impacted clinical care in a patient encounter. Other rotation activities included Ultrasound Rounds where residents presented a critical appraisal of a POCUS-related journal article, Pediatric Ultrasound Rounds at The Hospital for Sick Children, and an advanced POCUS workshop day. Of 13 eligible residents, 12 (92%) completed at least one study assessment. However, only 8 residents (62%) completed both the pre-test and post-test, 8 residents (62%) completed the end-of-rotation survey, and even fewer residents (42%) completed the delayed post-rotation survey. Residents felt the quality of the ultrasound rotation was excellent (mean score 4.7 on 5-point Likert scale). There was an increase in test scores from a baseline of 51.5% to 70.8% on the post-rotation test (p=0.02). Three months after the rotation, 100% of residents reported feeling either comfortable or extremely comfortable teaching and using the core POCUS topics covered in the curriculum. All residents reported that they would recommend the rotation to their colleagues without hesitation. All residents passed the national ultrasound certification examination at the end of the rotation. Conclusion: A four-week curriculum was effective in teaching EM residents POCUS skills. Further study is required to determine the ideal method for teaching POCUS skills in this group.
LO099: Colchicine in acute and recurrent pericarditis: a meta-analysis
Authors: Costain N. , Choi S. , Vaillancourt C.
Published: June 2016

Introduction: Pericarditis is a common disease associated with significant morbidity. In adults with pericarditis, we sought to determine if colchicine, in addition to standard therapies, could reduce the incidence of pericarditis recurrence, shorten the duration of symptoms and minimize adverse effects associated with other therapies. Methods: We followed PRISMA guidelines. We performed an electronic search (February 2015) through MEDLINE, EMBASE, CENTRAL, Web of Science, and Google scholar. Online trial registries were searched and reference lists were handed searched. Our search strategy had no limitations on study design, outcome of interest, hypothesis, language, dates or publication status. Inclusion criteria for selected manuscripts were: RCTs; adults; outpatient therapy; and idiopathic/viral/autoimmune pericarditis etiology. Cohen's unweighted kappa for inter-observer agreement was calculated. Data was extracted using a standardized data collection tool. Following assessment of homogeneity between studies, we performed a meta-analysis using (fixed or random) effect models and report odds ratios (OR) with 95% confidence intervals (CI). We assessed bias using GRADE. Results: We screened 647 titles/abstracts, and selected 34 manuscripts for full review (kappa 0.86, CI 0.76-0.96). 7 manuscripts met all inclusion criteria comprising 1,275 patients. We obtained the following OR with 95% CI: 1) For the overall incidence of recurrence of pericarditis (OR 0.32; CI 0.24-0.42); 2) For recurrent pericarditis at 18-months (OR 0.32; CI 0.23-0.44); 3) For event-free of recurrent pericarditis at 18-months follow-up (OR 3.40; CI 2.46-4.70); 4) For persistent symptoms at 72 hours (OR 0.29; CI 0.21-0.41); and 5) For the overall adverse events rate (OR 1.27; Cl 0.84-1.92). Conclusion: Colchicine reduces the number of pericarditis recurrences and the duration of symptoms in patients with recurrent or acute pericarditis. Unless there are contraindications to its use, colchicine should be prescribed in all cases of uncomplicated pericarditis, along with standard therapy.
LO100: Electrical vs chemical cardioversion in patients with acute atrial fibrillation: a multicenter parallel group randomized controlled clinical trial

Published: June 2016

Introduction: Patients with atrial fibrillation (AF) of <48 hours duration often present to Emergency Departments (ED). Electrical or chemical cardioversion can be employed to restore normal sinus rhythm (NSR). Current guidelines make no recommendations between these two methods and the management decisions are left to the discretion of the treating physician. The objective of this study was to compare these two approaches in terms of ED length of stay (LOS), success (conversion to NSR) and health related outcomes. Methods: At six western Canadian EDs, eligible adult patients were assigned to one of two groups following concealed allocation and using a centralized computer-generated randomization method: electrical cardioversion (EC) first (followed by chemical cardioversion [CC] if the primary method failed) or CC first (followed by EC if the primary method failed). Baseline evaluation/interview and 3/30 day telephone contact were completed and documented using the REDCap data-platform. Adverse events were externally adjudicated in a blinded-fashion. An intention to treat analysis was performed. Results: Overall, 84 patients participated in the study (EC: 43; CC: 41); the median age was 60 years (interquartile range [IQR]: 50, 66), and 38% were female. The baseline patient characteristics in both groups were similar. The median LOS between randomization and conversion to NSR (intervention LOS) was 1.0 hrs (IQR: 0.8, 2.7) in EC vs. 3.1 hrs (IQR: 2.0, 3.9) in CC (p<0.001); more patients in EC were discharged from the ED within 4 hours than in the CC group (65% vs. 32%; p=0.002). The majority of EC patients (84%) converted to NSR after the first attempt while half of the patients did so in the CC group (49%). No differences were observed in terms of adverse events (26% vs. 24%; mostly minimal), hospitalizations (0%), and patients’ health outcomes (physician/ED visits, admissions, stroke) and status (SF-8) at 3 and 30 days, in groups EC and CC groups, respectively. Conclusion: Electrical cardioversion was associated with a statistically significant and clinically meaningful reduction in the LOS when compared to cardioversion using chemical management. Similarities in the proportions of success, adverse events and health outcomes between the groups would support the use of electrical shock as the first approach for cardioversion in clinical practice.
LO101: Predicting short-term risk of arrhythmia among patients with syncope: the Canadian Syncope Arrhythmia Risk Score

Introduction: Suspicion of arrhythmias among syncope patients is the leading cause of emergency department (ED) referrals and hospitalization. However, the risk factors for short-term arrhythmias are not well defined. We sought to develop a risk prediction tool to identify syncope patients at risk for 30-day arrhythmia or death after ED disposition. Methods: This prospective cohort study involved 6 academic EDs that enrolled adult syncope patients. We collected standardized variables at index presentation from history, clinical examination, investigations including ECG, and patients’ disposition. Adjudicated outcomes included death (due to arrhythmia or unknown cause), arrhythmia or procedural intervention to treat arrhythmias within 30-days after ED disposition. Multivariable logistic regression was used to derive the model; bootstrap sampling for internal validation and to estimate shrinkage and optimism. Results: 5,010 adult syncope patients (mean age 53.4 years, 54.8% females, and 9.5% hospitalized) were enrolled with 106 (3.6%) patients suffering arrhythmia or death within 30-days after ED disposition. Of 39 candidate predictors examined, eight were included in the final model: vasovagal predisposition, heart disease, any ED systolic blood pressure <90 or >180 mmHg, troponin (>99%ile), QRS duration >130msec, QTc interval >480msec and ED diagnosis of cardiac, or vasovagal syncope [Optimism corrected c-statistic: 0.91 (95%CI 0.87-0.93); Hosmer-Lemeshow p=0.08]. The Canadian Syncope Arrhythmia Risk Score had a risk ranging from 0.2% for a score of -2 to 74.5% for a score of 8. Sensitivity for threshold score ≤-1 was 100% (95% CI 96.5-100) and specificity for a score of ≥4 was 97.0% (95% CI 96.5-97.5). Conclusion: The Canadian Syncope Arrhythmia Risk Score can improve acute management of ED patients with syncope by better identification of those at higher-risk for short-term arrhythmia or death. Once validated, the tool can be used to guide disposition decision and can also aid in selection of patients for out-of-hospital cardiac monitoring if discharged home.
LO102: ALiEM AIR-Pro Series: identifying quality content from blogs and podcasts for the senior emergency medicine resident
Authors: Zaver F. , Lin M.
Published: June 2016

Introduction / Innovation Concept: In 2008, the Accreditation Council for Graduate Medical Education endorsed a change such that EM residency programs can decrease their synchronous conference experiences by up to 20% in exchange for asynchronous learning - Individualized Interactive Instruction (III). Identifying quality online resources that would also fulfill III’s reporting criteria (program director monitoring, evaluation component, faculty oversight, program effectiveness) is challenging. Using crowdsourced expertise, the Approved Instructional Resources (AIR) series from Academic Life in Emergency Medicine (ALiEM) was created in 2014 to provide a credible method to identify quality educational blogs and podcasts. The identified resources, however, focused on basic content with limited utility for more senior residents. We thus created the AIR-Pro series in 2015, aimed to cover more advanced concepts. Methods: The AIR-Pro series is a continuously building curriculum covering a new subject area every 2 months. For each area, 6 EM Chief Residents identify 3-5 advanced clinical questions. Using FOAMsearch.net to search blogs and podcasts, relevant posts are scored by 8 reviewers from the AIR-Pro Board (faculty and chief residents at various institutions). The scoring instrument contains 5 measurement outcomes (7-point Likert scale): recency, accuracy, educational utility, evidence based, and references. The AIR-Pro Approved label is given to posts with a score of ≥28 (out of 35) points and these are featured in the blog posting. For scores of 26-27, an Honorable Mention label is given if Board members collectively felt that they were valuable. For each AIR-Pro subject area, a multiple choice quiz is written based on the featured posts. Educator dashboard access of the Google Drive quizzes is given to program directors for monitoring. If approved by their program director, EM residents receive official III credit upon completion of each quiz. Curriculum, Tool, or Material: As of Jan 1, 2016, there have been 2 modules published on ALiEM with 1,220 (Cardiovascular) and 1,059 (Trauma) pageviews worldwide. Although early in development, 21 different institutions are using the AIR-Pro Series with over 150 residents completed the cardiovascular and trauma quizzes. We anticipate more because the original AIR Series has over 73 programs using it for III credit. Conclusion: The AIR-Pro series is a novel, objective, crowdsourced approach towards identifying quality, educational, social media content for the advanced EM resident.
MP002: Beyond rater cognition: the impact of supervisor continuity on the quality of documented work-based assessments
Authors: Cheung W. , Dudek N. , Wood T.J. , Frank J.R.
Published: June 2016

Introduction: Barriers to completing high quality work-based assessments (WBAs) include relational factors such as the episodic and fragmented interaction that often exists between clinical supervisors and trainees. In an effort to increase supervisor-trainee continuity, the Department of Emergency Medicine at the University of Ottawa created Clinical Teaching Teams (CTT) in which a resident and clinical supervisor work matched shifts together throughout the year. The aim of this study was to determine the impact of supervisor-trainee continuity on the quality of assessments documented on Daily Encounter Cards (DECs). Methods: DECs completed by 20 clinical supervisors were collected and sorted into three groups representing differing degrees of supervisor-trainee continuity (Group 1: CTT emergency resident; Group 2: non-CTT emergency resident; Group 3: non-CTT off-service resident). DECs were scored using the Completed Clinical Evaluation Report Rating (CCERR), a 9-item instrument that has been shown to have reliable ratings and the ability to discriminate the quality of completed DECs. Scores were analyzed using a univariate ANOVA with “mean CCERR score” as the dependent variable and “continuity group” and “supervisor” as between-subject variables. The relationship between CCERR scores and number of CTT encounters over time was examined using a repeated measures ANOVA with “encounter number” as the within-subject factor. Results: Mean CCERR scores for the CTT (21.0, SD=5.8), non-CTT (21.9, SD=4.2), and off-service (20.7, SD=4.0) groups differed (p=0.019). A subsequent pairwise comparison demonstrated a statistically significant difference in means between the non-CTT and off-service groups (p=0.04); however, this 1.2 difference on the 45-point CCERR scale is unlikely to be of any educational significance. The number of repeated encounters did not have a statistically significant effect on CCERR scores (p=0.43) indicating that DEC quality did not improve with greater supervisor-trainee interaction. Conclusion: DEC quality as scored by the CCERR was low for all three groups. Increasing supervisor continuity alone did not result in higher quality assessments of clinical performance. Additional research focusing on the educational alliance that develops between supervisor and trainee may hold greater promise.
MP004: Analgesia for acute gingivostomatitis: a national survey of pediatric emergency physicians
Authors: Ali S. , MacLellan J. , Curtis S.J. , Baserman J. , Dixon A.
Published: June 2016

Introduction: Gingivostomatitis is a common, painful pediatric presentation, and yet, few studies are available to guide management. We aimed to describe pediatric emergency physicians’ current practice patterns, with respect to analgesic use in children with acute gingivostomatitis. Methods: A national survey was conducted at all 15 national academic pediatric centres. Electronic surveys were distributed to pediatric emergency physicians using a modified Dillman protocol; non-respondents received paper surveys via post. Data were collected regarding demographics, clinical behaviour, knowledge, perceived barriers and factors that influence practice. Results: Overall response rate was 74% (150/202). Most physicians preferred the combination of acetaminophen and ibuprofen (72%) to either agent alone (ibuprofen 19%, acetaminophen 7%). The preferred second-line analgesics were oral morphine (48%, 72/150) and compounded topical formulas (42%, 64/150). The most commonly cited compounded agent was Benadryl plus Maalox (23%, 35/150). Clinical experience with a medication appeared to be the greatest influence on practice patterns; with 52% (78/149) ‘strongly agreeing’ that this was a factor. The most commonly cited barrier to adequate analgesia was difficulty in administration of topical or oral medication to children. Conclusion: As with many other painful conditions, acetaminophen and ibuprofen are reported to be used most frequently. However, oral morphine and topical compounded agents were also frequently prescribed. Regardless of patient age, physicians preferred oral morphine as a second-line agent to treat pain from severe gingivostomatitis. Future research should focus on determining which analgesic and route (oral or topical) is the most effective and best-tolerated choice.
MP007: Constats de décès à distance et disponibilité des services préhospitalier d’urgence
Authors: Gauthier M. , Lebon J. , Tanguay A.B. , Bégin F.
Published: June 2016

Introduction: L’Unité de coordination clinique des services pré-hospitaliers d’urgence (UCCSPU) est un plateau clinique rattaché au CSSS Alphonse-Desjardins (CHAU Hôtel-Dieu de Lévis) qui permet un soutien médical à distance des patients transportés par ambulance dans la région de Chaudières-Appalaches (CA). En 2011, un projet novateur, devenu programme par la suite, a été instauré afin de réaliser des constats de décès à distance (CDD). Le but du programme est de réduire le nombre de transport de patients décédés vers les hôpitaux afin de remettre rapidement en service l’équipe ambulancière. Le but de l'étude est de décrire et comparer le taux de CDD et le gain de temps sur la remise en service de l’équipe ambulancière avant et après l’implantation du programme de CDD dans deux différentes régions géographiques (Chaudières-Appalaches et Saguenay-Lac-St-Jean (SLSJ)). Par la suite, déterminer s’il existe une distance minimale à partir de laquelle ce gain de temps est nul pour chaque région. Methods: Il s’agit d’une étude rétrospective portant sur 204 personnes réparties en 4 groupes : 2 groupes témoins [CA pré-CDD (50) et SLSJ pré-CDD (50)] et 2 groupes d’étude [CA post-CDD (52) et SLSJ post-CDD (52)] pour les deux régions. Le pourcentage de CDD réussi (taux de réalisation) par région et les gains de temps entre chaque groupe (intra- et inter-région) en fonction de la distance avec le centre hospitalier (CH) ont été calculés. Results: Pour un même nombre de patients, le taux de réalisation de CDD est similaire entre les deux régions [CA=80% (6 mois) et SLSJ=76% (4 mois)]. Le temps de remise en service des ambulances est différent (p<0.05) inter-région se caractérisant par des gains de temps moyens de 62 min (CA) et 28 min (SLSJ). Enfin, la distance minimale où le gain de temps est nul est de moins de 5 km pour chaque région. Conclusion: L’implantation du programme de CDD permet un gain de temps favorisant un retour plus rapide des services pré-hospitalier d’urgence si la distance entre le lieu du CDD et du CH est supérieure à 5 km. De plus, le gain en temps est proportionnel avec la distance entre le lieu du CCD et le CH.

Published: June 2016

Introduction: The addition of computerized physician order entry (CPOE) to Emergency Departments in recent years has led to speculation over potential benefits and pitfalls. Recent studies have shown benefits to CPOE, though there lacks sufficient evidence on how it could change physician behaviour. Physician practices are known to be difficult to change, with getting evidence into daily practice being the main challenge of knowledge translation. Our study aims were to determine if well-designed electronic order sets for CPOE improved MD practices. Methods: The Calgary Zone Pain Management in the Emergency Department Working Group relied on a GRADE-based literature review for identifying best practices for analgesia and antiemetics, resulting in soft changes to the dedicated analgesia and antiemetic electronic order set noting working group preference, and emphasizing hydromorphone over morphine, as well as 4 mg ondansetron over 8 mg. The new electronic order set was started in the only Calgary Region order entry system on December 11th, 2014. Data was collected from July 2014 - May 2015. A Yates chi-squared analysis was completed on all orders in a category, as well as the subgroups of ED staff and residents, and orders placed using the new order set. Results: A total of 100460 orders were analyzed. The use of hydromorphone increased significantly across all 4 EDs. IV hydromorphone use increased (5.82% of all opioid orders up to 26.93%, P<0.0001) with a reciprocal decline in IV morphine (67.81% of all opioid orders down to 46.56%, P<0.0001). Similar effects were observed with ondansetron 4 mg IV orders increasing (1.37% of all ondansetron orders to 18.64%, P<0.0001) with a decrease in 8 mg dosing (15.75% of all ondansetron orders to 7.23%, P<0.0001). These results were replicated to a lesser degree in the non-ED staff and non-order set subgroups. Implementation of the new order set resulted in an increase of its use (37.64% of all opioid orders up to 49.29%, P<0.0001). Finally, a cost-savings analysis was completed showing a projected annual savings of $185,676.52 on medications alone. Conclusion: This data supports the manipulation of electronic order sets to help shape physician behaviour towards best practices. This provides another strong argument towards the benefits of CPOE, and can help maintain best practices in Emergency Medicine.
MP012: Is there an association between the use of cardiac ultrasound and survival outcomes in patients arriving to the emergency department in cardiac arrest? The second Sonography in Hypotension and Cardiac Arrest in the Emergency Department (SHOC-ED 2) Study
Authors: Beckett N. , Atkinson P.R. , Fraser J. , French J. , Lewis D.
Published: June 2016

Introduction: The use of cardiac point of care ultrasound (PoCUS) to assess cardiac arrest patients is widespread, although not mandated by advanced cardiac life support (ACLS) guidelines. This study aims to examine if the use of ultrasound, along with the findings on ultrasound are associated with a difference in outcomes of cardiac arrest patients in the emergency department (ED). Methods: A retrospective database and chart analysis was completed for patients arriving to a tertiary ED in asystole or PEA cardiac arrest, between 2010 and 2014. Patients were excluded if aged under 19, or with a previous DNR order. Patients were grouped based on whether PoCUS was used during ACLS (PoCUS group) and those without PoCUS (control group). Multiple data were abstracted from charts using a standardized form. Data was analyzed for the return of spontaneous circulation (ROSC), survival to hospital admission (SHA), and survival to hospital discharge (SHD), as well as initial cardiac activity findings on PoCUS. Results: 230 patients met the study inclusion criteria, with 44 (19%) in the control group, and 186 (81%) in the PoCUS group. In the PoCUS group 20 (11%) had cardiac activity (Positive PoCUS) and 166 (89%) had no cardiac activity recorded. The control group had a higher rate of SHA than the PoCUS group (27%; 95% CI 15-43% vs. 10%: 6-15%, p = 0.0046), however there was no difference in frequency of ROSC (control: 37%; 24-55% vs. PoCUS 26%; 20-33%, p = 0.1373) or SHD (control: 7%, 95% CI 1-19%; PoCUS: 2%, 95% CI 0-5%, p = 0.0858). Positive PoCUS patients had a higher frequency of ROSC (75%; 50-91% vs. 20%; 15-27%, p < 0.001) and SHA (25%; 9-49% vs. 8%; 4-13%, p = 0.0294) than patients with no PoCUS cardiac activity, however there was no difference in the rate of SHD between the positive PoCUS patients (0%; 0-17%) and patients with no PoCUS cardiac activity (2%; 0-5%, p = 1.0000). Conclusion: Our results suggest that there is no difference in survival between cardiac arrest patients receiving PoCUS and those who do not. Although finding positive cardiac activity on PoCUS is associated with greater ROSC and survival to hospital admission, it does not identify patients with a final outcome of survival to hospital discharge.
MP013: A portrait of rural pre-hospital services in the province of Québec
Authors: Bourdon E. , Tanguay A.B. , Tounkara F.K. , Marois A. , Fleet R.
Published: June 2016

Introduction: Rural emergency departments (EDs) are important safety nets for 20% of Canadian citizens. In Quebec, the province’s 26 rural EDs treat an average of 19,000 patients/year and are on average 300 km from levels 1 and 2 trauma centers. These distances signify that Emergency Medical Services (EMS) play a considerable role in the care of rural patients. EMS in Quebec province are private local services. There are no published reports on EMS in rural Quebec. As part of a larger study on rural emergency care, this descriptive study aimed at offering a comprehensive portrait of EMS. Methods: We conducted semi-structured interviews with managers of all paramedic services in rural Quebec. Interview questions focused on number of transports, training, availability of telemetry, GPS technologies, and work schedules. Results: Fifty managers of the 51 private companies serving the 26 rural EDs in Quebec were interviewed (response rate 98%). All were primary care paramedics (PCP). In 2010, EMS transported 40,671 patients, with 10,228 emergency transports to the rural EDs. A total of 7956 inter-facility transfers were conducted, 1499 of them emergency. Each ED required between 88 and 700 inter-facility transfers. A total of 60% (n=31/51) had GPS technology, only 25% (n=13/51) had telemetry features. Work schedules varied with 13% (n=7/51) of companies offering shifts of less than 12 hours, 28% (n=14/51) 24/7 weekly shifts, and 56% (n=29/51) a combination. Conclusion: This is the first study to describe rural EMS in Quebec. The finding that Quebec’s rural EDs are served by 51 privately-owned companies is unique in Canada. The considerable number of EMS transports, including inter-facility transfers, may reflect lack of local resources in rural EDs, the vulnerable population served, or the increased trauma risk in rural areas. Future studies should examine inter-facility transport reasons, costs, times and adequate training/scope of EMS practice.
MP016: Measuring frailty can help emergency departments identify seniors at risk of functional decline after minor injuries
Authors: Allain-Boulé N. , Sirois M. , Griffith L.E. , Émond M. , Batomen Kuimi B.
Published: June 2016

Introduction: The CETI team has shown that around 18% of otherwise independent seniors remain in a state functional decline up to six months after a minor injury. In that context, frailty may be associated with increased likelihood of decline. As most seniors consult Emergency Departments (EDs) when injured, measuring frailty may help identify those at risk of functional decline. Objectives: This study aims to 1) describe frailty in the sub-group of independent community-dwelling seniors consulting Emergency Departments (ED) for minor injuries, 2) examine the association between frailty and functional decline three months post-injury, 3) ascertain the predictive accuracy of frailty measures and Emergency Physicians’ (EPs) for functional decline. Methods: Prospective cohort in 2011-2013 among 1072 seniors aged ≥ 65, independent in basic daily activities, evaluated in Canadian EDs for minor injuries and discharged home. Frailty was assessed at EDs using the Canadian Study of Health and Aging-Clinical Frailty Scale (CSHA-CFS) and the Study of Osteoporotic Fracture index (SOF). Functional decline was defined as a loss ≥ 2/28 on the Older American Resources Services scale three months post-injury. Generalized mixed models were used to explore differences in functional decline across frailty levels. Areas Under the Receiver operating characteristic curve (AUC) were used to ascertain the predictive accuracy of frailty measures and EPs’ clinical judgement. Results: The SOF and CSHA-CFS were available in 342 and 1058 participants, respectively. The SOF identified 55.6%, 32.7%, 11.7% patients as robust, prefrail and frail. These CSHA-CFS (n=1058) proportions were 51.9%, 38.3% and 9.9%. The 3-month incidence of functional decline was 12.1% (10.0%-14.6%). The AUCs of the CSHA-CFS and the EPs’ were similar (0.548 - 0.777), while the SOF was somewhat higher (0.704 - 0.859). Conclusion: Measuring frailty in community-dwelling seniors with minor injuries in EDs may enhance current risk screening for functional decline. However, before implementation in usual care, feasibility issues such as inter-rater reliability and acceptability of frailty tools in the EDs have to be addressed.

Published: June 2016

Introduction: Health promotion and disease prevention have been increasingly recognized as activities within the scope of emergency medicine. Exercise prescription by physicians has been shown to improve outcomes in obesity, cardiovascular disease, and many other diseases. An estimated 600,000 Canadians receive the majority of their care from emergency departments (ED), representing a substantial opportunity for health promotion. Our study examined the frequency of exercise prescription by emergency physicians (EPs) and determined factors that influence decisions to prescribe exercise. Methods: A national, confidential 22-item survey was distributed to Canadian EPs via email by the CAEP survey distribution protocol in November/December 2015. Demographics, exercise prescription rates and self-reported exercise habits were collected. Results: A total of 332 EPs responded. 92.4% of EPs reported being at least moderately active. 62.7% of EPs often or always council their patients about preventative medicine (smoking cessation, drug and alcohol use, diet and safe sex). However, only 23.8% often or always ask about their exercise habits. Even fewer (12.7%) often or always prescribe exercise. Training background significantly predicted level of comfort prescribing exercise. CCFP trained EPs were 5.1 (p = 0.001) times more likely than trained EPs to respond 'yes' they feel comfortable prescribing exercise, and 3.7 (p = .009) times more likely to respond 'sometimes'. CCFP (EM) trained EPs were 3.5 (p < 0.001) times more likely than trained EPs to respond 'yes' they feel comfortable prescribing exercise, and 2.0 (p = .031) times more likely to respond 'sometimes'. 76.1% of respondents believe that other EPs rarely or never prescribe exercise. Of respondents, only 36% feel comfortable prescribing exercise. The majority of EPs (73.4%) believe that the ED environment did not allow adequate time for exercise prescription. Conclusion: The majority of EPs council their patients regarding other forms of preventative medicine but few prescribe exercise to their patients. Available time in the ED was cited as a significant barrier to exercise prescription. CCFP trained EPs are more comfortable prescribing exercise, suggesting that their training may better educate and prepare them to council patients on exercise compared to trained EPs. Further education may be required to standardize an approach to prescribing exercise in the ED.
MP019: Systematic review of the management of lateral epicondylitis using transdermal nitroglycerin
Authors: Hunter M. , Bhargava A. , Lang E.
Published: June 2016

Introduction: Lateral epicondylitis (LE), also known as tennis elbow, is an overuse-underuse tendinopathy originating from the forearm extensor tendons of the elbow. An emerging therapy for the treatment of LE is the use of transdermal nitroglycerin (NTG) patches for pain relief and improved function. Our systematic review assesses 18 to 65 year old patients with clinically diagnosed LE and no structural damage or longstanding elbow injury to determine if transdermal NTG patches provide improved short term and long term pain relief as well as improved function in comparison with placebo. Methods: We included randomised controlled trials (RCT’s) of NTG patch use versus placebo for the treatment of LE. Prospective comparison studies were also eligible for assessing the long term pain relief of NTG patch use. We performed a literature search using MEDLINE, EMBASE, SportDiscus and the Cochrane Database of Systematic Reviews. English language articles were retrieved for review up to November 2015. Risk of bias within the studies was assessed regarding randomisation, allocation sequence concealment, blinding and selective outcome reporting. Results: Three RCT’s were included that compared transdermal NTG patch use (two studies with 1.25mg/24h and one study comparing 0.72, 1.44 and 3.6mg/24h) versus a placebo to treat LE. One prospective comparison study of five years duration was included as a follow-up to one of the included RCT’s to assess pain and function five years after the discontinuation of therapy. Data was not pooled because of heterogeneity in study methods and outcomes. The use of transdermal NTG patches provided short term pain relief (2-6 weeks for dosing of 0.72mg/24h or 1.25mg/24h) compared with placebo as suggested by three RCT’s. Long term pain relief was improved by NTG patch use compared with placebo at six months in one RCT, but not at five years in a prospective comparison study. Function improved in two different RCT’s with NTG patch use at 0.72mg/24h and 1.25mg/24h when compared to placebo. Five years after cessation of treatment, there was no difference between NTG patch and placebo. Conclusion: Overall, the included studies demonstrate that the use of NTG patches compared to placebo improves short term and long term pain relief, as well as elbow function. However, more studies are required to bridge the gaps between the existing studies and reduce heterogeneity between the study designs.

Published: June 2016

Introduction: Delays in definitive management of difficult airways in the Emergency Department (ED), often involving coordination with expert consultation from Anesthesia and/or Otolaryngology, can lead to devastating outcomes. Currently at our ED there is no standardized approach to identifying and/or managing predicted difficult airway scenarios. We sought to determine the most common factors contributing to predicted difficult airways in the ED, and areas of time delays in securing a definitive airway. Methods: We conducted a retrospective analysis at a tertiary academic centre (>160,000 ED visits/yr) over a 5 year period. A research assistant screened all cases of “Stat” pages from the ED to the Anesthesia service. An ED clinician performed a thorough review of the charts to confirm difficult airway cases. A single reviewer extracted data on patient demographics, factors associated with a difficult airway, and specific time intervals throughout a patient’s clinical course. We present descriptive statistics with 95%CI. Results: 45 cases met our inclusion criteria between Jan 2010-Dec 2014. 16 were excluded and a total of 29 cases of difficulty airways in the ED were included in our final analysis. The average age was 56.7 (95% CI 50.1-63.4) years, and 68.9% were male. The most common factors contributing to difficult airway included: Obesity (48.2%), previous history of head/neck malignancy/radiation (27.6%), and facial edema (20.7%). 25 (86.2%) required expert assistance from Anesthesia/Otolaryngology for definitive airway, and 8 (27.6%) survived to hospital discharge. The mean time between decision to intubate and “Stat” anesthesia page was 14.0 (95% CI 8.7-19.3) mins. The mean time from “Stat” anesthesia page to arrival of anesthesia MD was 8.4 (95% CI 6.0-10.7) mins. The mean time between arrival of anesthesia MD and definitive airway was 12.1 (95% CI 7.4-16.8) mins. The mean time between decision to intubate and definitive airway was 35.5 (95% CI 27.9-43.1) mins. Conclusion: We found a number of common factors contributing to a patient’s risk of having a predicted difficult airway in the ED, as well as areas of significant time delays in the unstandardized, multidisciplinary management of these cases. Future work is needed on developing, implementing, and evaluating more standardized difficult airway response protocols in the ED.

Introduction: Despite strong evidence that antithrombotic drugs in atrial fibrillation/flutter (AF) patients reduce stroke risk, previous emergency department (ED) pre-novel anticoagulant (NOAC) studies have shown that most discharged patients are not optimally treated. This study sought to determine baseline antithrombotic management in AF patients, and appropriate antithrombotic prescription upon ED discharge since the introduction of NOACs. Methods: Consecutive AF patients discharged by the ED physician from three academic EDs in Toronto, Canada were retrospectively identified using ECG data. Primary AF was defined as AF in patients ≥18 years without congenital heart disease or other acute medical conditions. All management and disposition decisions were left to the discretion of the emergency doctor. Results: From July 2012 to October 2014, 691 patients with primary AF were identified. Of these, 34.4% (n=238) had new onset AF and 66.4% (n=459) were discharged home directly from the ED. Of those with previously known AF (n= 453), 44.2% (n=200) were on anticoagulation at ED arrival (warfarin 59.5%, dabigatran 23.0%, rivaroxaban 11.5%); 25.6% (n=116) on antiplatelets, and 29 (6.4%) on both. Based on 2012 Canadian AF guidelines, 60.1% of those who should have received anticoagulation were receiving it. In discharged patients meeting de novo criteria for anticoagulation (n=130), 20.0% (n=26) were started on anticoagulation and 23.1% (n=30) on antiplatelets. In patients with CHADS2 score ≥ 2 (n=61), 26.2% (n=16) were started on anticoagulation. Warfarin (73.1%) was most commonly prescribed followed by dabigatran (15.4%) and rivaroxaban (11.5%). Age was the only inverse independent predictor for appropriate anticoagulation (OR 0.92 per 5 year of age 95% CI 0.89-0.95, p <0.0001) i.e. older patients were less likely to be anticoagulated. The CHADS2 score was not an independent predictor of appropriate anticoagulation. Conclusion: Our study shows a persistent gap in the antithrombotic treatment of ED AF patients irrespective of their risk.
MP024: Ultrasound-guided femoral nerve block versus fascia iliaca block for hip fractures in the emergency department: a randomized pilot study

Published: June 2016

Introduction: Regional anesthesia has been shown to be an effective pain control strategy for patients presenting with hip fractures in the emergency department. There are two common methods for performing this block: the femoral nerve block (FNB) and the fascia iliaca compartment block (FICB). The objective of this pilot study is to determine whether one of these two ultrasound-guided block techniques provides superior analgesia to emergency department patients with hip fractures. Methods: Emergency physicians at a single institution were randomized to the FNB or FICB training groups. Participants completed a 2-hour practical workshop covering the technique, followed by a questionnaire to assess their comfort with the block. They were asked to perform their assigned nerve block on any patient in the ED presenting with a hip or femur fracture. Physician comfort level and patient pain scores using a visual analog scale (VAS) were recorded before and after the nerve block were recorded. Comparisons were performed using Student’s t-test and Fisher’s exact test. Results: A total of 20 physicians were enrolled in the study, 10 in the FNB group and 10 in the FICB group. There were no significant baseline differences between the groups with respect to ultrasound or nerve block experience. Following the training, 100% of participants in both the FNB group and FICB group felt comfortable performing the block. Nerve blocks were performed in 30/51 (58.8%) of eligible patients in the FNB group and 6/11 (54.5%) in the FICB group (p=1.0). On the 10-point VAS, pain scores decreased by a mean of 4.9 (SD 3.5) in the FNB group and 8.3 (SD 2.4) in the FICB group (p=0.056). In practice, physicians felt comfortable performing the FNB in 52.8% of cases, and the FICB in 85.7% of cases (p=0.21). Mean time to completion of the blocks was similar between the two groups (19 vs 18 mins, p=0.83). Conclusion: In this pilot study, we found a non-significant trend towards improved analgesia and higher physician comfort with the ultrasound-guided FICB compared with the FNB in patients with hip fractures. We found no differences in time to performing the blocks. These results require confirmation with a larger sample size.

Introduction: The decision to treat with parenteral therapy may reflect a variable practice pattern among emergency physicians and represent an opportunity to standardize care. Our objective was to describe physician level practice variation for IV therapies in patients with low-acuity presentations and quantify the contribution of IV therapy to prolonging ED LOS. Methods: Using administrative data merged with computerized physician order entry information we sampled 48 months of patient variables across four urban EDs (Jan 1, 2014 - Dec 22, 2015). Eligible patients: 1. presented with complaints of abdominal pain, nausea and vomiting or diarrhea or had a discharge diagnosis of cellulitis 2.were in a low acuity category (Canadian Triage and Acuity Scale - CTAS 3 or 4) 3.were triaged to non-stretcher zones of the ED and 4.were not admitted to hospital. The primary outcome was the physician-level variation in the decision to order IV therapies for this patient group; namely one or more of the following: IV fluids, opioid analgesia, anti-emetics and antibiotics. Secondary outcomes were a comparison of ED LOS, ED revisits at 7 days and ED revisits resulting in admission at 7 days for the IV and non-IV groups. Results: Our analysis included 31 802 patient visits treated by 185 physicians. The average patient age was 37.8 years with 64.3% being female and the majority triaged as CTAS 3 (82.5%). On average 24% of these visits were treated with IV therapies; 90th percentile; 34%. For physicians seeing in excess of 100 cases, the variation in IV therapy use ranged from 1% to 47%. Patients receiving IV therapies demonstrated a 44% greater average LOS (6.2 hours vs 4.3 hours) and those receiving IV therapies had higher 7-day ED revisit rates (12.0% vs 8.8%) as well as 7-day ED revisits resulting in readmission (2.4% vs 1.0%). 'mso-spacerun:yes'> Secondary outcomes were a comparison of ED LOS, ED revisits at 7 days and ED revisits resulting in admission at 7 days for the IV and non-IV groups. Conclusion: This is the first study to examine physician preference for the use of IV therapies in a low-acuity population and has demonstrated in excess of a 47-fold variation between both extremes of use. Reducing practice variation in this area of ED care by standardizing indications for IV therapies could result in more rational resource utilization and improved throughput.

Introduction: Atrial fibrillation and flutter (AFF) are the most common arrhythmias presenting to the emergency department. Without anticoagulation, AFF increases stroke risk; individuals with paroxysmal AFF have a similar prognosis. A coordinated ED AFF electronic order-set and management pathway was developed at our institution. The primary objective of this study was to measure rates of appropriate anticoagulation (AAC) on discharge from the ED for patients presenting with AFF not previously on antithrombotic or anticoagulant medications. Secondary objectives included comparison of the following outcomes pre and post-pathway (PRE & POST): AFF Clinic referral rates, ED return rates, and mortality. Methods: This was a retrospective case series of patients presenting to our quarternary care ED with AFF pre and post AFF pathway implementation. Cases were identified using an administrative database covering 120 000 annual ED visits. Trained research assistants and the primary investigator extracted data from the electronic medical record. 20% of all charts were double collected to ensure accuracy (k=0.85). Descriptive variables were described using counts, means, medians and confidence intervals. Chi-square statistics of dependent samples were calculated for the primary outcome. Results: We examined 307 cases of AFF presenting to our ED (n=130 PRE; n=177 POST). Demographic variables were similar PRE and POST: mean age (66.0 [95%CI 63.8-68.3] PRE; 65.0 [63.0-67.0] POST), % male (59.2% PRE; 59.3% POST), presenting rhythm (66.2% A.fib [58.0-74.3] A. flutter 29.2% [21.4-37.0] PRE; 61.0% A.fib [53.8-68.1] A. flutter 17.5% [11.9-23.1] POST), and CHADS2VASC score (2.1 [1.8-2.4] PRE; 1.9 [1.7-2.1] POST). The rate of AAC rose from 39.1% PRE to 77.8% POST (P < 0.01). AFF clinic referral rates increased from 16.9% PRE to 25.4% POST (not significant). ED return rates within 30 days for AFF, CHF, major bleeding and CVA were unchanged. 30 day mortality rates were not statistically different (1.5% PRE vs. 2.8% POST). Conclusion: The implementation of a coordinated ED AFF pathway was associated with significant improvements in the proportion of patients discharged with appropriate anticoagulation who had not previously been on antithrombotic or anticoagulant medications. ED return rates and mortality did not change significantly.
