Introduction: Podcasts and blog posts are gaining popularity in Free Open Access Medical education (FOAMed). However, there remains a paucity of research comparing the two media for undergraduate medical education. This study aims to investigate if there are differences in medical students’ usage conditions, knowledge retention and preferences in the two types of media (podcasts, blog posts). Methods: Medical students were block-randomized to either the podcast or blog post group according to their year of schooling. They completed an online assessment of their baseline knowledge on the subject matter and preferences within the various types of media. Participants then received access to learning materials and were given four weeks to complete the follow-up assessment. Simple descriptive statistical data were used to detail student preferences. Paired samples t-tests and a Repeated Measures Analysis of Variance (RM-ANOVA) were conducted to assess knowledge acquisition. A carry forward analysis was used to impute missing data from students lost to follow-up. Results: A total of 65 medical students participated in our study (podcasts n=33, blog posts n=32). The initial survey suggests that students prefer general topic discussion and “approach-to” themes (68% and 84%, respectively). 55% of students in the podcast group preferred podcasts that were less than 30 minutes. None of the blog post group preferred a shorter text, and each blog post required a mean of 25 minutes to read. Completion of at least one follow-up assessment was comparable (68% podcasts, 70% blog posts). The podcast listeners tended to engage in multiple activities while using the learning material (e.g. at least 2-3 of the following: driving, eating, chores, taking notes, exercising), while the blog readers tended to do fewer activities (e.g. only 1 of the following: taking notes, eating, only reading). Both groups showed significant improvements in their test scores (Asthma: 22% improvement, Toxicology: 29%; p<0.01 for both), with blog posts demonstrating a larger but non-significant difference (RM-ANOVA, Topic*Modality F(1,59)=0.001, p=0.973). Conclusion: This study suggests that podcasts and blog posts significantly improve medical student knowledge retention to a similar degree, but differ in usage conditions.

Introduction: The Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP) found a significant rise in trampoline-related injuries from 1999-2005, many of which required hospitalization. In 2007 and again in 2013, the Canadian Pediatric Society (CPS) recommended against the recreational use of trampolines at home. The purpose of this study was to evaluate the impact of this policy statement on trampoline-related injuries in Halifax, Nova Scotia. Methods: Trampoline injury data was obtained from the CHIRPP database at the IWK Health Centre, the paediatric referral hospital for the Maritimes. The data was stratified according to the timing of the CPS policy statement (before: 2001-2006, after: 2008-2013 and after reaffirmation 2013-2015). Data variables included mechanism, site, nature and context of injury. The data were evaluated using SPSS and chi-squared tests. Results: Since the 2007 CPS policy statement, an average of 162 per 10,000 ED visits at the IWK Health Centre were the result of trampoline-related injuries compared to 95 per 10,000 pre-policy. The majority of injuries (76-80%) occurred in children 5-14 years of age. Recreational use at home in the yard was the most common location of the accident (78-88%), with most injuries occurring on the trampoline mat itself (83-85%) due to incorrect landing (32-35%), falls (21-27%), or being struck by a person or object (24-25%). Soft tissue injuries (15-17%), sprains (19-22%) or fractures (40-46%) to the elbow (11-12%), forearm (5-9%) or ankle (19-21%) continued to be the most common nature and sites of injuries. The injury data before compared to after the CPS policy statement did not differ significantly in gender, the mechanism of injury, the type of injury, or body part involved (p-value >0.05). There was a significant difference in the number of injuries between age groups post-policy, with more occurring in children less than 4 and between the age of 10-14 (p<0.009). Moreover, where the trampoline injury was located was also significantly different post-policy with more injuries occurring in sports/recreational facilities (p<0.001). Conclusion: Trampolining is a high-risk activity with injuries occurring predominantly in children and youth. Despite the recommendations brought forth by the CPS, trampoline-related injuries remain an important source of pediatric injuries at the IWK Health Centre in Halifax, Nova Scotia.

Introduction: Delirium is a very prevalent cognitive impairment in elderly inpatients, but it often goes undetected, especially in the emergency department (ED). The tools currently available to screen or diagnose patients at risk of delirium are very time-consuming and are impossible to systematically perform in the ED environment. For this reason, short tests are necessary to screen for delirium in this fast-paced setting. The objective of this study was to evaluate the performance of the French version of the Rapid Assessment Test for Delirium (4AT) for the detection of delirium and cognitive impairment in older patients. The 4AT takes less than 2 minutes to administer, which is a great advantage on the others tests. Methods: The study was conducted in four emergency departments across the province of Québec. Participants were independent or semi-independent patients aged 65 and older, admitted to hospital and who had an 8-hour exposure to the ED. The Telephone Interview for Cognitive Status (TICS) was administered at the initial interview and the Confusion Assessment Method (CAM) as well as the 4AT were administered to patients twice a day during their ED or hospital stay. The 4AT’s sensitivity and specificity were compared to that of the CAM (for delirium), and to that of the TICS (for cognitive impairment). Results: 324 patients were included in the study, with a mean age of 76 years old. Among the recruited participants, 21 (6.5%) had a prevalent delirium according to the CAM, and 30 (10.2%) had an incident delirium. According to the 4AT, 48 patients (14.9%) had cognitive impairment and 81 (25.2%) had a prevalent delirium. According to the TICS, 87 patients (29.2%) have cognitive impairment. The 4AT has a sensitivity of 68,4% (IC 95% : 47,5-89,3) and a specificity of 73.2% (IC 95% : 67,8-78,7) for delirium, and a sensitivity of 50% (IC 95% : 35,9-64,1) and a specificity of 87,0% (IC 95% : 81,2-92) for cognitive impairment. Conclusion: The French Version of the 4AT could be a fast and reliable screening tool for delirium and cognitive impairment in ED. Further research is necessary for its validation in the ED.

Introduction: We previously reported that a targeted knowledge translation (KT) intervention was associated with a trend towards increased awareness and knowledge of the Choosing Wisely Canada (CWC) emergency medicine (EM) recommendations. We wished to assess if the intervention changed physician practice, specifically looking at the imperative “do not order lumbar XRs for non-traumatic low back pain unless red flags exist”. Methods: A departmental KT initiative was implemented in April 2016 and consisted of a 1-hour seminar reviewing the CWC-EM recommendations, access to a video cast, departmental posters, and a before and after awareness survey. The effectiveness of our intervention was assessed by analyzing the frequency of lumbar XR imaging conducted for low back pain before and after the introduction of our intervention at a tertiary teaching hospital emergency department. All patient visits for the complaint of low back pain were included. The rates of XR imaging from June 2014 to September 2014 for the pre-intervention period and June 2016 to September 2016 for the post-intervention period were collected and analyzed using Fisher exact tests. A sample size of 683 was required to detect a 5% change with an alpha of 0.05 and a power of 80%. Results: Baseline characteristics of patients were similar for the pre- and post-intervention periods. There was a total of 781 patient visits for low back pain in June to September 2014 and 672 in June to September 2016. The XR imaging rate for low back pain increased from 12% (95% CI 9.9-14.5) to 16.2% (95% CI 13.6-19.2) following the intervention (p=0.023). Conclusion: We previously demonstrated a trend towards increased awareness and knowledge of the CWC EM recommendations following a knowledge translation initiative. Baseline XR imaging rates for low back pain were lower than what has been reported. We observed that our intervention was associated with an increased frequency of imaging for low back pain. This may be due to a contrarian effect. We feel this calls into question the role of knowledge translation initiatives where physician practice already closely adheres to pre-established recommendations.

Introduction: The Pulmonary Embolism Severity Index (PESI) score predicts short-term mortality from pulmonary embolism and low-risk patients suitable for home therapy. However, it is unknown if it is a driver for disposition decisions for emergency department (ED) patients. The primary objective of this study was to define the relationship between disposition decisions and the PESI score in Calgary zone hospitals. Methods: The PESI score was calculated retrospectively for 576 patients presenting to one of four Calgary zone hospitals for pulmonary embolism over the last 2 years. The calculated PESI score allowed the mortality risk of each patient to be estimated for very low risk (Class I, 0-1.6% 30-day mortality rate), low risk (Class II, 1.7-3.5% 30-day mortality rate), intermediate risk (Class III, 3.2-7.1% 30-day mortality rate), high risk (Class IV, 4.0-11.4% 30-day mortality rate), and very high risk (Class V, 10.0- 24.5% 30- day mortality rate). The patients were grouped based on being admitted to the hospital for inpatient care, or discharged for outpatient care. Descriptive statistics were used to describe the data. Results: Of the 576 patients, 317 (55%) were discharged and 259 (45%) were admitted to the hospital for inpatient care. Among admitted patients, 20.5% were considered Class I, 29.3% were Class II, 24.3% were Class III, 17.6% were Class IV, and 8.1% were Class V. Among discharged patients, 53.9 % were Class I, 25.6% were Class II, 15.5% were Class III, 4.4% were Class IV, and 0.6% were Class V. Of the 25 very high-risk (Class V) patients, 2 (8.0%) were discharged from the ED and treated as outpatients. Of the 223 very low risk (Class I) patients, 171 (76.7%) were discharged and 52 (23.3%) were admitted to hospital. Conclusion: A significant percentage of pulmonary embolism patients admitted to Calgary Zone hospital wards are PESI low risk (29.3%) or very low risk (20.5%). Implementation of a PESI score-based disposition pathway could improve the safety, cost-effectiveness and quality of ED disposition decisions for PE.

Introduction: The objective of this systematic review was to investigate the psychometric properties and diagnostic performance of instruments used in the emergency department to identify pediatric mental health and substance use problems. Methods: A search of seven electronic databases and the grey literature was conducted. Studies assessing any instrument to identify and or diagnose mental illness, emotional or behavioural problems, or substance use disorders in pediatric patients with presentations for mental health or substance use issues were considered eligible for inclusion. Two independent reviewers judged the relevance and study quality of the studies. A descriptive analysis of the outcomes was reported. Results: From 4832 references, 14 studies were included. Eighteen instruments were evaluated for identifying suicide risk, alcohol use disorders, mood disorders, and ED decision-making. The HEADS-ED has good inter-rater reliability (r=0.785) for identifying general mental health problems and modest evidence for ruling out patients requiring hospital admission (positive likelihood ratio, LR+=6.30). The internal consistency varied for tools to screen for suicide risk (α=0.46-0.97); no tools have both high sensitivity and high specificity. The Ask Suicide-Screening Questionnaire (ASQ) is highly sensitive (98%) and provides strong evidence to rule out risk (negative likelihood ratio, LR−=0.04). Among tools to screen for alcohol use disorders, a two-item tool based on DSM-IV criteria was found to be the most accurate in identifying patients with a disorder (area under the curve: 0.89), and has modest evidence to rule in and rule out risk (LR+=8.80, LR−=0.13). Conclusion: Reliable, valid, and accurate instruments are available for use with pediatric mental health ED visits. Based on available evidence, emergency care clinicians are recommended to use the HEADS-ED to rule in ED admission, ASQ to rule out suicide risk, and DSM-IV two-item tool to rule in/rule out alcohol use disorders.

Introduction: While methods have been developed to assess pain and provide analgesia to hospitalized intubated patients, little is known about current EMS practices in providing similar care during air and land medical transports. Therefore, we sought to determine if opioid analgesia is provided to intubated patients during transportation in out-of-hospital setting. Methods: We conducted a health record review examining electronic records of intubated patients transported by Ornge in 2015. Ornge is the exclusive provider of air and land transport of critically ill patients in Ontario, Canada with over 18,000 transports per year. We identified cases using Ornge’s database and selected intubated patients meeting inclusion criteria. A standardized data extraction form was piloted and used by a single trained data extractor. The primary outcome was frequency of administration and dose adequacy of an opioid analgesic. Secondary outcomes included: choice of analgesics used (fentanyl, hydromorphone or morphine), adverse events, and impact of age, sex, or reason for transfer on pain management. We present descriptive statistics. Results: Our strategy identified 500 potential cases, of which 448 met our inclusion criteria. Among those 448 patients, 154 (34.4%) were females, 328 (73.4%) received analgesia and 211 (64.3%) received more than one dose during transport (median frequency of 2 doses, IQR=1 to 3). The average transport time was 148 minutes and repeated dosing (>1 repeat dose) occurred primarily (45.5%) in transports of over 180 minutes. Fentanyl was the most commonly used analgesic (97.6%) and most commonly used dose was 50 micrograms (51.8%). Adverse events occurred in 8 (2.5%) patients with 5 patients having new hypotension (MAP <65 mm Hg). There was no significant difference in administration of analgesia based on patient’s age or sex (68.8% of females and 75.3% of male patients received analgesia). Interestingly, 30.8% of patients repatriated to originating-hospital received analgesia compared to 72.3% of patients receiving analgesia for all other reasons for transfers. Conclusion: More than 73% of intubated patients transported by Ornge received an opioid analgesic, most commonly fentanyl. We found no clinically relevant difference in the administration of analgesics based on age, sex or reason for transfer other than home repatriation.

Introduction/Innovation Concept: Free Open Access Medical education (FOAM) is a rapidly emerging medium for the dissemination of medical knowledge, especially in Emergency Medicine. However, the most contributors to FOAM are EM attendings who write on established platforms which they also maintain. EM learners have difficulty breaking into this quickly evolving field. In an effort to encourage FOAM involvement of trainees early in their careers, CanadiEM recruited 10 junior residents and medical students with the purpose of developing the skills necessary to contribute to FOAM. These Junior Editors actively participate in the blog workflow, developing writing, editorial, and management skills necessary to operate a high-traffic EM website. Methods: Potential candidates were recruited by placing an advertisement and application on the CanadiEM website. 10 medical students or junior residents were invited to online group video interviews and were all accepted as Junior Editors (JE). Senior CanadiEM staff held online training sessions for all new JEs on how to use Wordpress to create, edit and publish posts, as well as basics in Search Engine Optimization. The junior editors collaboratively developed an instructional document containing the information they learned during these sessions. JEs then volunteered for editorial jobs via an online messaging system (Slack) as they became available. After uploading the draft of each post, the final products are reviewed by senior Editor and feedback was given to each JE. Curriculum, Tool, or Material: All JEs have learned to use the Wordpress blogging platform to create, edit, and upload posts; optimize blog posts for search engines. Following their own interests, some JEs have also learned to edit podcasts, promote the blog on social media resources (Twitter and Facebook), create infographics, and copy-edit blog posts. Conclusion: After 8 months, the JE program has yielded 6 very active editors who maintain a strong blog workflow, have well-developed social media skills, and are actively involved in developing their own content for future posts. The JE program is a strong pathway to introduce medical trainees to both the technical and creative aspects of FOAM and serves as a novel approach to transition students from passive utilization of online content to active contributors.

Introduction: In Ottawa, STEMI patients are transported directly to percutaneous coronary intervention (PCI) by advanced care paramedics (ACPs), primary care paramedics (PCPs), or transferred from PCP to ACP crew (ACP-intercept). PCPs have a limited skill set to address complications during transport.The objective of this study was to determine what clinically important events (CIEs) occurred in STEMI patients transported for primary PCI via a PCP crew, and what proportion of such events could only be treated by ACP protocols. Methods: We conducted a health record review of STEMI patients transported for primary PCI from Jan 1, 2011-Dec 21, 2015. Ottawa has a single PCI center and its EMS system employs both PCP and ACP paramedics. We identified consecutive STEMI bypass patients transported by PCP-only and ACP-intercept using the dispatch database. A data extraction form was piloted and used to extract patient demographics, transport times, and primary outcomes: CIEs and interventions performed during transport, and secondary outcomes: hospital diagnosis, and mortality. CIEs were reviewed by two investigators to determine if they would be treated differently by ACP protocols. We present descriptive statistics. Results: We identified 967 STEMI bypass cases among which 214 (118 PCP-only and 96 ACP-intercept) met all inclusion criteria. Characteristics were: mean age 61.4 years, 78% male, 31.8% anterior and 44.4% inferior infarcts, mean response time 6 min, total paramedic contact time 29 min, and in cases of ACP-intercept 7 min of PCP-only contact time.A CIE occurred in 127 (59%) of cases: SBP<90 mmHg 26.2%, HR<60 30.4%, HR>100 20.6%, malignant arrhythmias 7.5%, altered mental status 6.5%, airway intervention 2.3%, 2 patients (0.9%) arrested, both survived. Of the CIE identified, 54 (42.5%) could be addressed differently by ACP vs PCP protocols (25.2% of total cases). The majority related to fluid boluses for hypotension (44 cases; 35% of CIE). ACP intervention for CIEs within the ACP intercept group was 51.6%. There were 6 in-hospital deaths (2.8%) with no difference in transport crew type. Conclusion: CIEs are common in STEMI bypass patients however a smaller proportion of such CIE would be addressed differently by ACP protocols compared to PCP protocols. The vast majority of CIE appeared to be transient and of limited clinical significance.

Introduction: There is increasing evidence that emergency room physicians or primary care physicians can definitively manage many uncomplicated paediatric fractures without orthopaedic follow-up. This strategy leads to a reduction in radiation exposure and decreased costs to patient families and the healthcare system without impacting patient outcomes. The aim of this study was to determine whether patients who sustained a toddler’s fracture of the tibia required orthopaedic surgeon follow-up. Methods: A retrospective analysis including patients who presented to the Hospital for Sick Children (SickKids) for management of toddlers’ fractures between Jan 2009 and Dec 2014 was performed. Results: 186 patients (115 males, 72 females) with an average age of 2.00 (range 0.2-3.9) were included in the study. The mean number of clinic visits including initial consultation in the emergency department was 2.00 (±1.0). The mean number of radiology department appointments was 2.76 (±1.1) where patients received a mean number of 5.86 (±2.6) radiographs. Complications were minimal and no patient developed a non-union nor re-fractured. All patients achieved clinical and radiographic union. To date, no patient has returned to clinic or undergone surgery for concerns regarding leg length inequality or malalignment. Conclusion: Our series supports reduced clinical follow-up of patients with a toddler’s fracture of the tibia. If the diagnosis can be made on the initial radiographs, emergency room physicians or primary care providers can definitively manage these patients with appropriate immobilization that can be removed by the parents between 3-4 weeks after the injury. A fracture clinic follow-up is only necessary if the diagnosis cannot be made on the initial radiographs. Our toddler’s fracture pathway will reduce patient radiation exposure and reduce costs incurred by the healthcare system and patients’ families without jeopardizing patient outcomes.

Introduction: There is increasing evidence that emergency room physicians or primary care physicians can definitively manage many uncomplicated paediatric fractures without orthopaedic follow-up. This strategy leads to a reduction in radiation exposure and decreased costs to patient families and the healthcare system without impacting patient outcomes. The aim of this study was to determine whether patients who sustained an isolated 5th metatarsal fractures require orthopaedic surgeon follow-up. Methods: A retrospective analysis including patients who presented to the Hospital for Sick Children (SickKids) for management of metatarsal fractures from 2009-2014 was performed. Results: 124 patients (66 males, 58 females) with mean age of 11.3 (SD=2.9) years old were included in the study. Complications were minimal with no patients requiring operative management. There were zero non-unions and 3 delayed unions. Despite zero instances of surgical correction and a low complication rate, fracture clinic resource utilization was substantial. Fractures were managed with a mean number of 3.1 (SD=0.98) clinic visits, including initial evaluation in the emergency department. A mean number of 2.8 (SD=1.1) radiology department visits were conducted, with a mean of 8.1 (SD=3.8) x-rays total per patient. Conclusion: Our series supports reduced clinical follow-up of patients with isolated 5th metatarsal fractures. If the diagnosis can be made on the initial radiographs, ER physicians or primary care providers can definitively manage these patients with appropriate immobilization. A fracture clinic follow-up is only necessary if the diagnosis cannot be made on the initial radiographs. Our clinical care pathway will reduce radiation exposure and reduce costs incurred by the healthcare system and patients’ families without jeopardizing patient outcomes.

Introduction: London Health Sciences Centre (LHSC) includes two academic, urban hospitals in London, Canada. The hospital-standardized mortality ratio (HSMR) is consistently higher than provincial and national averages. Unpublished data reveals that sepsis contributes the largest number of statistically unexpected deaths to LHSC’s HSMR calculation. Factors contributing to in-hospital sepsis mortality are hypothesized to include demography, emergency department (ED) flow or sepsis treatment. Methods: Retrospective chart review of patients aged >=18 years, presenting to an LHSC ED between 01 Nov 2014 and 31 Oct 2015, with >=2 SIRS criteria and/or ED suspicion of infection and/or ED or hospital discharge sepsis diagnosis (ICD-10 diagnostic codes A4xx and R65). Data were abstracted from electronic health records. Regional, provincial and national data was retrieved from CIHI and Statistics Canada. Results: Median age and sex in London and across Canada are similar (48.2 years vs 48.9 years; 48% male vs 49% male). Baseline prevalences of diabetes, hypertension, COPD and mood disorders were similar in the Local Health Integration Network and Ontario (6% vs 7%, 19% vs 19%, 3% vs 4%, and 10% vs 8%). Median “Physician Initial Assessment,” (PIA) times for sepsis patients at LHSC were faster than median Canadian PIA times for CTAS I and II patients (CTAS I: 7 min vs 11 min, CTAS II: 34 min vs 54 min), and slower for CTAS III-V patients (CTAS III: 98 min vs 79 min, CTAS IV: 99 min vs 66 min, CTAS V: 132 min vs 53 min). Median ED length of stay for admitted, high acuity (CTAS I-III) patients was 6 h at LHSC versus 10 h across Canada.Median [IQR] time to intravenous fluid resuscitation was 60.5 min [29.8-101.2] for septic shock patients and 77.0 min [36.0-127.0] for expired patients. Median [IQR] time to antibiotics was 130 min [73.0-229.0] for sepsis patients, 106 min [60.0-189.0] for severe sepsis patients, and 82 min [42.2-142] for septic shock patients. Conclusion: Excess sepsis-related mortality at LHSC is not convincingly related to patient demographics or ED flow. Gains may be made by improving time to antibiotics and IV fluids.

Introduction: Emergency physicians increasingly encounter young patients with protracted, forceful hyperemesis associated with heavy cannabis use, previously termed “cyclic vomiting.” The national discourse on liberalization of cannabis has largely ignored this poorly understood condition. We wondered to what degree hyperemesis cannabis is an idiosyncratic reaction, like motion sickness or migraine, versus a more predictable dose-response effect of heavy, prolonged use. Methods: As part of a larger case-control study using structured interviews, we measured cannabinoid concentrations in scalp hair of both cases and controls. Cases were required to have an emergency visit for vomiting, 2+ episodes of severe vomiting in the previous year, history of near-daily use of cannabis for 6+ months, positive urine Δ9-tetrahydrocannabinol (THC) and age 16-55 years; exclusion criteria were chronic opioid use, synthetic cannabinoid use, or established alternative diagnosis. Age- and sex-matched chronic cannabis-using controls without vomiting were identified via social referral primarily from the cases themselves. Scalp hair was analyzed for THC, cannabinol (CBN), cannabidiol (CBD) and 11-nor-9-carboxy-THC (THC-COOH) by LC-MS/MS (limit of quantification ~15 pg/mg hair; accuracy <5%) in an independent laboratory blinded to subject classification. Results: We obtained satisfactory hair and urine samples from 18 cases (median [IQR] age 27 [20,31] years; 12 male) and 13 controls. THC and CBN concentrations were higher in cases than controls (THC 240 [120,820] vs 99 [73, 290] pg/mg; CBN 63 [33, 260] vs 15 [negative, 76] pg/mg; each P<0.05). CBD and THC-COOH were often unquantifiable to undetectable in both cases and controls. Conclusion: Hyperemesis cannabis patients have substantially higher hair cannabinoid concentrations than their peers without vomiting, although there is some overlap. The association cannot demonstrate a direct dose-response with THC--confounding (e.g. other cannabinoids, external smoke deposition), altered metabolism and reverse causation (e.g. seeking temporary symptom relief by using more cannabis) could also yield a positive association. Nevertheless, these findings support counselling patients with hyperemesis to reduce or discontinue using cannabis. They also support national regulatory initiatives including education, labelling, and progressive taxation based on potency intended to discourage excessive use.

Introduction: Consultation in the emergency department (ED) is a common component of emergency health care. Consultation is defined as a case in which an ED physician (EP) requests the services of another physician (consultant) for an ED patient to assist, advise, and/or transfer care when the care required is beyond the expertise of the EP’s practice. While consultation is generally considered required and beneficial for patient care, consultation can also have a negative impact by incurring delays in patient flow and disposition. These delays contribute to ED crowding, patient dissatisfaction and, in some cases, worse health outcomes. Using an a priori protocol and accepted methodology, the aim of this systematic review was to update a previous review on the same topic and determine the proportion of 1) ED visits that involve consultation and 2) consultation cases that result in admission. PROPSPERO registration number: CRD42017054054. Methods: Literature search involved multiple electronic databases (e.g., MEDLINE and EMBASE) and grey literature (e.g., Google Scholar and conference abstracts). Study selection was conducted independently by two reviewers and determined by consensus among the two reviewers with disagreements resolved by a third party. Data extraction was conducted independently by two reviewers and determined by consensus among the two reviewers with disagreements resolved by a third party. A descriptive analysis was conducted. Outcome measure data were aggregated and reported with suitable descriptive statistics such as raw or weighted mean, median, or proportion with 95% confidence interval. Results: Literature search yielded 1,584 studies, of which 65 were included. Two-thirds of studies were conducted in USA or Canada. Of the 65, 54 were focused on a particular patient group or consulting specialty (e.g., psychiatry) while 11 considered the general ED population. Of these 11, the median proportion of ED visits involving consultation was 26%. The median proportion of cases with consultation that resulted in admission was 60%. Conclusion: Consultations in the ED are quite common and many of these cases result in admission. Given their frequency of occurrence and increasing ED crowding, efforts to reduce consult delays and expedite disposition appear warranted.

Introduction: Diabetes mellitus is an increasingly prevalent chronic condition that is usually managed in an outpatient setting. However, the emergency department (ED) plays a crucial role in the management of diabetic patients, particularly for those who are presenting with newly diagnosed diabetes. Little research has been done to characterize the population of patients presenting to the ED with hyperglycemia with no previous diagnosis of diabetes. The objective of this study was to describe the epidemiology, treatment, and outcomes of patients who were newly diagnosed with diabetes in the ED and to compare those with newly diagnosed type I versus type II diabetes. Methods: A one-year health records review of newly diagnosed diabetes patients ≥18 years presenting to one of four tertiary care EDs was conducted. All patients with a discharge diagnosis of hyperglycemia, diabetic ketoacidosis or hyperosmolar hyperglycemic syndrome were screened, but only those who did not have a previous history of diabetes were included. Trained research personnel collected data on patient characteristics, management, disposition, and outcome. Descriptive statistics were used to summarize the data where appropriate. Results: Of 645 patients presenting with hyperglycemia in the study period, 112 (17.4%) were newly diagnosed diabetes patients. Of these patients, 30 (26.8%) were later diagnosed with type I diabetes and 82 (73.2%) were diagnosed with type II diabetes. For the newly diagnosed type I patients the mean (SD) age was 27.6 (9.9) and the mean (SD) age for type II patients was 52.4 (14.1). Of all the new onset patients, 26.8% were diagnosed with diabetic ketoacidosis. The percentage of patients diagnosed with diabetic ketoacidosis was higher in type I than type II (63.3% vs 13.4%; P<0.01). A total of 49 (43.8%) patients were admitted to the hospital, and more patients with type I were admitted compared to those with type II (66.7% vs 35.4 %; P<0.01). Conclusion: Limited research has been done to describe patients newly diagnosed with diabetes in the ED. Patients with type I were found to be more likely to present to the ED with serious symptoms requiring admission to hospital. Our findings demonstrate that the ED may have a strong potential role for improving diabetic care, by providing future opportunities for education and follow-up in the ED to reduce complications, particularly in type I.

Introduction: Early recognition of sepsis is key in delivering timely life-saving interventions. The role of paramedics in recognition of these patients is understudied. It is not known if the usual prehospital information gathered is sufficient for severe sepsis recognition. We sought to: 1) evaluate the paramedic medical records (PMRs) of severe sepsis patients to describe epidemiologic characteristics; 2) determine which severe sepsis recognition and prediction scores are routinely captured by paramedics; and 3) determine how these scores perform in the prehospital setting. Methods: We performed a retrospective review of patients ≥18 years who met the definition of severe sepsis in one of two urban Emergency Departments (ED) and had arrived by ambulance over an eighteen-month period. PMRs were evaluated for demographic, physiologic and clinical variables. The information was entered into a database, which auto-filled a tool that determined SIRS criteria, shock index, prehospital critical illness score, NEWS, MEWS, HEWS, MEDS and qSOFA. Descriptive statistics were calculated. Results: We enrolled 298 eligible sepsis patients: male 50.3%, mean age 73 years, and mean prehospital transportation time 30 minutes. Hospital mortality was 37.5%. PMRs captured initial: respiratory rate 88.6%, heart rate 90%, systolic blood pressure 83.2%, oxygen saturation 59%, temperature 18.7%, and Glasgow Coma Scale 89%. Although complete MEWS and HEWS data capture rate was <17%, 98% and 68% patients met the cut-point defining “critically-unwell” (MEWS ≥3) and “trigger score” (HEWS ≥5), respectively. The qSOFA criteria were completely captured in 82% of patients; however, it was positive in only 36%. It performed similarly to SIRS, which was positive in only 34% of patients. The other scores were interim in having complete data captured and performance for sepsis recognition. Conclusion: Patients transported by ambulance with severe sepsis have high mortality. Despite the variable rate of data capture, PMRs include sufficient data points to recognize prehospital severe sepsis. A validated screening tool that can be applied by paramedics is still lacking. qSOFA does not appear to be sensitive enough to be used as a prehospital screening tool for deadly sepsis, however, MEWS or HEWS may be appropriate to evaluate in a large prospective study.

Introduction: Utilization of CT imaging has risen dramatically with increases in availability, but without corresponding improvements in patient outcomes. Previous attempts to improve imaging appropriateness via guideline implementation have met with limited success, with commonly cited barriers including a lack of confidence in patient outcomes, medicolegal risk, and patient expectations. The objective of this project is to improve CT utilization and appropriateness by addressing common barriers through clinical decision support (CDS) embedded in clinical practice. Methods: This matched-pair cluster-randomized trial saw 12 Alberta EDs with CT scanners randomized to receive CDS for diagnostic imaging. After extensive site engagement to recruit emergency medicine and diagnostic imaging leadership and stakeholders and understand local contexts, half of the sites received CDS for mild traumatic brain injury (MTBI) based on the Canadian CT Head Rule, while the remainder received CDS for suspected pulmonary embolism (PE), including the Pulmonary Embolism Rule-out Criteria (PERC), Wells Score, age-adjusted D-dimer and CT pulmonary angiography (CTPA) use. Hardcopy CT order forms including quantitative decision support, source literature and patient handouts were developed and adapted and integrated into workflow as per local site preference. Regular physician and site report cards on CT utilization and CDS use were also provided. The primary outcome was diagnostic imaging utilization for patients with MTBI and suspected PE. Results: During the study period, 144 emergency physicians at 6 EDs saw 3,278 patients with MTBI and 146 emergency physicians at six matched comparison EDs saw 18,606 patients with suspected PE. Use of CDS was highly variable by site, ranging from 0% to 29% of CT orders for MTBI and from 13% to 75% of CTPA orders for suspected PE. Impact on CT utilization, appropriateness, diagnostic yield is currently under investigation, but is expected to be limited at many sites given the variable adoption of decision support. Conclusion: A comprehensive CDS intervention to improve evidence-based imaging has met with variable uptake. Meaningful and widespread sustained improvements in practice will likely require incentives, accountability measures and leadership authority to enforce change.

Introduction: Decreasing readmission rates and return emergency department (ED) visits represent a major challenge for health organizations. Seniors are especially vulnerable to discharge adverse events which can result in unplanned readmissions and loss of physical, functional and/or cognitive capacity. The ACE Collaborative is a national quality improvement initiative that aims to improve care of elderly patients. We aimed to adapt Mount Sinai’s Care Transitions program to our local context in order to decrease avoidable readmissions and ED visits among seniors. Methods: We performed a prospective pre/post implementation cohort study. We recruited frail elderly hospitalized patients (≥50 years old) discharged to home and at risk of readmission (modified LACE index score≥7/12). We excluded patients being discharged to long-term nursing homes or institutions. Our intervention is based on selected strategic ACE Care Transitions best practices: transition coach, telehealth personal response services and a structured discharge checklist. The intervention is offered to selected patients before hospital discharge. Our primary outcome is a 30-day post-discharge composite of hospital readmission and return ED visit rate. Our secondary outcomes are functional autonomy, satisfaction with care transition, quality of life, caregiver strain and healthcare resource use at recruitment and at 30-days follow-up. Hospital-level administrative data is also collected to measure global effect of practice changes. Results: The project is currently ongoing and preliminary results are available for the pre-implementation cohort only. Patients in this cohort (n=33) were mainly men (61%), aged 75±10 years and presented an OARS score (Activities of Daily Living instrument that ranges from 0-28) of 5.6±4.9. At 30 days post-discharge, the patients in our cohort had a 42.4% readmission rate (14 hospitalisations) and a 54.5% return ED visit rate (18 visits). For the same time period, readmission and return ED rates for all patients in the same corresponding age-group at the hospital level were 14.4% and 21.9%, respectively. Further results for our post-intervention cohort will be presented at CAEP 2017. Conclusion: Our cohort of elderly patients have high readmission and return ED visit rates. Our ongoing quality improvement project aims to decrease these readmissions and ED visits.

Introduction: Hospital shootings are rare events that pose extreme and immediate risk to staff, patients and visitors. In 2015, the Ontario Hospital Association mandated all hospitals devise an armed assailant Code Silver protocol, an alert issued to mitigate risk and manage casualties. We describe the design and implementation of ASSIST (Active Shooter Simulation In-Situ Training), an institutional, full-scale hybrid simulation exercise to test hospital-wide response and readiness for an active shooter event, and identify latent safety threats (LSTs) related to the high-stakes alert and transport of internal trauma patients. Methods: A hospital-wide in-situ simulation was conducted at a Level 1 trauma centre in downtown Toronto. The two-hour exercise tested a draft Code Silver policy created by the hospital’s disaster planning committee, to identify missing elements and challenges with protocol implementation. The scenario consisted of a shooting during a hospital meeting with three casualties: a manikin with life-threatening head and abdomen gunshot wounds (GSWs), a standardized patient (SP) with hypotension from an abdominal GSW, and a second SP with minor injuries and significant psychological distress. The exercise piloted the use of a novel emergency department (ED)-based medical exfiltration team to transport internal victims to the trauma bay. The on-call trauma team provided medical care. Ethnographic observation of response by municipal police, hospital security, logistics and medical personnel was completed. LSTs were evaluated and categorized using video framework analysis. Feasibility was measured through debriefings and impact on ED workflow. Results: Seventy-six multidisciplinary medical and logistical staff and learners participated in this exercise. Using a framework analysis, the following LSTs were identified: 1) Significant communication difficulties within the shooting area, 2) Safe access and transport for internal casualties, 3) Difficulty accessing hospital resources (blood bank) 4) Challenges coordinating response with external agencies (police, EMS) and 5) Delay in setting up an off-site command centre. Conclusion: In situ simulation represents a novel approach to the development of Code Silver alert processes. Findings from ethnographic observations and a video-based analysis form a framework to address safety, logistical and medical response considerations.

Introduction: Patients presenting to the Emergency Department (ED) may require clarification of their goals of care (GOC) to ensure they receive treatments aligned with their values. However, these discussions can be difficult to conduct for multiple reasons, including lack of time in a busy ED, competing priorities and a limited relationship with the patient. Few studies have examined the perceived challenges faced by Emergency Physicians in conducting GOC discussions. This study sought to contextualize and discern the barriers and facilitators to having these conversations as reported by Emergency physicians. Methods: An interdisciplinary team of Emergency Medicine, Palliative Care and Internal Medicine providers developed an online survey comprised of multiple choice, Likert-scale and open-ended questions to explore four domains of GOC discussions: training; communication; environment; and personal beliefs. Invitations and scheduled reminders were sent to 275 ED physicians at six academic sites in a Canadian urban centre, including 49 EM residents. Results: 105 (46%) staff physicians and 23 (47%) residents responded with similar representation from all sites. Differences were reported in the frequency of GOC discussions: 59% of staff physicians conduct several per month whereas 65% of residents conduct less than one per month. Most agreed that GOC discussions are within their scope of practice (92%), they feel comfortable (96%), and are adequately trained (73%) to have them; however, 66% reported difficulty initiating GOC discussions. 73% believed that admitting services should conduct GOC discussions, yet acuity was noted in the comments as a major determinant with initiating GOC discussions by ED physicians. Main barriers identified were lack of time, chaotic environment, lack of advanced directives and the inability to reach substitute decision makers. 54% of respondents indicated that the availability of 24-hour Palliative Care consults would facilitate GOC discussions in the ED. Conclusion: Emergency physicians are prepared to conduct goals of care discussions, but often believe they should instead be conducted by the patient’s admitting service. Multiple perceived barriers to goals of care discussion in the ED were identified, and a majority of respondents felt that the availability of Palliative Care in the ED may facilitate these discussions.
