Introduction: Emergency physicians (EP) are expected to be competent in a variety of uncommon but life-saving procedures, including the bougie assisted cricothyrotomy (BAC). Given the rarity and high-stakes nature of the BAC, simulation is often used as the primary learning and training modality. However, mental practice (MP), defined as the “cognitive rehearsal of a skill in the absence of overt physical movement”, has been shown to be as effective as physical practice in several areas, including athletics, music, team-based resuscitation and surgical skill acquisition. MP scripts incorporate cues from different sensory modalities to supplement instructions of how to complete the skill. We sought to explore EPs perspectives on the kinesthetic, visual and cognitive aspects of performing a BAC to inform the development of a MP BAC script. Methods: We undertook a qualitative interview study of EPs at a single tertiary care centre who had done a BAC in clinical practice. Participants were recruited using purposive sampling. The primary method for data collection was in-depth semi-structured qualitative interviews, which were recorded and transcribed verbatim. Data collection and analysis were concurrent; transcripts were coded independently by two researchers using qualitative content analysis on a coding framework based on the previously developed BAC checklist. At each procedural step, the kinesthetic, visual and cognitive cues that enhance MP were identified. Results: Eight EPs (5 staff; 3 Royal College residents) participated in the interviews. All participants had completed at least one BAC in their clinical practice. Data analysis revealed recurrent themes signifying successful completion of each procedural step. These include visual (ie. seeing a spray of blood upon entry into the airway) and kinesthetic (ie. feel of the tracheal rings on a finger) cues that describe aspects of the procedure not found in traditional teaching modalities, such as textbooks. Conclusion: Knowledge gleaned from the interviews of EPs with lived experience gives us a deeper insight into the sensory aspects of performing a BAC in clinical practice. We expect that using these experientially derived cues to inform the development of a MP script will increase its validity and applicability to learners and for skill maintenance. Future work includes evaluating the utility of the developed script in acquiring and maintaining competence performing the BAC.

Introduction: Formal ultrasound imaging, with use of ultrasound technicians and radiologists, provides a valuable diagnostic component to patient care in the Emergency Department (ED). Outside of regular weekday hours, ordering formal ultrasounds can produce logistical difficulties. EDs have developed protocols for next-day ultrasounds, where the patient returns the following day for imaging and reassessment by an ED physician. This creates additional stress on ED resources – personnel, bed space, finances – that are already strained. There is a dearth of literature regarding the use of next-day ultrasounds or guidelines to direct efficient use. This study sought to accumulate data on the use of ED next-day ultrasounds and patient oriented clinical outcomes. Methods: This study was a retrospective chart review of 150 patients, 75 from each of two different tertiary care hospitals in Saskatoon, Saskatchewan. After a predetermined start date, convenience samples were collected of all patients who had undergone a next-day ultrasound ordered from the ED until the quota was satisfied. Patients were identified by an electronic medical record search for specific triage note phrases indicating use of next-day ultrasounds. Different demographic, clinical, and administrative parameters were collected and analyzed. Results: Of the 150 patients, the mean age was 35.9 years and 75.3% were female. Median length of stay for the first visit was 4.1 hours, and 2.2 hours for the return visit. Most common ultrasound scans performed were abdomen and pelvis/gyne (34.7%), complete abdomen (30.0%), duplex extremity venous (10.0%). Most common indications on the ultrasound requisition were nonspecific abdominal pain (18.7%), vaginal bleeding with or without pregnancy (17.3%), and hepatobiliary pathology (15.3%). Ultrasounds results reported a relevant finding 56% of the time, and 34% were completely normal. After the next-day ultrasound 5.3% of patients had a CT scan, 10.7% had specialist consultation, 8.2% were admitted, and 7.3% underwent surgery. Conclusion: Information was gathered to close gaps in knowledge about the use of next-day ultrasounds from the ED. A large proportion of patients are discharged home without further interventions. Additional research and the development of next-day ultrasound guidelines or outpatient pathways may improve patient care and ED resource utilization.

Introduction: In Nova Scotia, under the Paramedics Providing Palliative Care program, paramedics can now manage symptom crises in patients with palliative care goals and often at home without the need to transport to hospital. Growing recognition that non-cancer conditions benefit from a palliative approach is expanding the program. Our team previously found treatment of pain and breathlessness is not optimized, pain scores are underutilized, and paramedics were more comfortable (pre-launch) with a palliative approach in cancer versus non-cancer conditions. Our objective was to compare symptom management in cancer versus non-cancer subgroup. Methods: We conducted a retrospective cohort study. The Electronic Patient Care Record and Special Patient Program were queried for patients with palliative goals from July 1, 2015 to July 1, 2016. Descriptive analysis was conducted and results were compared with a t-test and Bonferroni correction (alpha = p < 0.007). Results: 1909 unique patients; 765/1909 (40.1%) cancer and 1144/1909 (59.9%) non-cancer. Female sex: cancer 357/765 (46.7%), non-cancer 538/1144 (47.0%). Mean age cancer: 73.3 (11.65), non-cancer 77.7 (12.80). Top non-cancer conditions: COPD (495/1144, 43.3%), CHF (322/1144, 28.1%), stroke (172/1144, 15.0%) and dementia (149/1144, 13.0%). Comorbidities for cancer patients (range): 0 to 3; non-cancer 0 to 5. Most common chief complaint (CC) for cancer and non-cancer: respiratory distress, 10.8% vs 21.5%. Overall, no difference in proportion treated cancer vs non-cancer, 11.5% vs 10.1%, p = 0.35. Some difference in individual therapies: morphine 83/765 (10.8%) vs 55/1144 (4.8%), p < 0.001, hydromorphone 9/765 (1.2%) vs 2/1144 (0.2%), p = 0.014, salbutamol 38/765 (5.0%) vs 5/1144 (0.4%), p < 0.001 and ipratropium 27/765 (3.5%) vs 134/1144 (11.7%), p < 0.001, in addition to any support with home medication which is not queriable. Pre-treatment pain scores were documented more often than post-treatment in both groups (58.7% vs 25.6% (p < 0.001), 57.4% vs 26.9% (p < 0.001)). Conclusion: Non-cancer patients represent an important proportion of palliative care calls for paramedics. Cancer and non-cancer patients had very similar CC and received similar treatment, although low proportions, despite pre-launch findings that non-cancer conditions were likely to be undertreated. Pain scores remain underutilized. Further research into the underlying reason(s) is required to improve the support of non-cancer patients by paramedics.

Introduction: Canadian undergraduate medical Emergency Medicine (EM) rotations are often completed at either tertiary care centres or regional community hospitals. While the latter offer students exposure to different practice settings and population needs, many students perceive that teaching at tertiary care EM departments is superior to that in community hospitals. At our institution, third year undergraduate medical students complete three-week EM rotation at either a tertiary centre or a community hospital. We compared academic and clinical performance between students trained in tertiary care centres and students trained in community hospitals. Methods: Academic and clinical performance in EM was evaluated based on the results of an EM-specific multiple choice examination (MCQE) and an annual Objective Structured Clinical Exam (OSCE) assessing competency in a broad range of clinical scenarios commonly addressed in EM. The 40-question MCQE is administered quarterly and a mix of old and new questions are used to ensure consistency. The OSCE is administered annually and relies on the same principal to remain consistent. OSCE scores are binary: pass or fail. We reviewed MCQE and OSCE scores from three consecutive cohorts of students. Students were pooled into two groups, tertiary and community, based on the site of their EM rotation. Mean MCQE and OSCE performance were compared between the two groups of students using two-tailed unpaired T tests. Chi squared tests were used to identify significant differences in scores between cohorts. Results: MCQE and OSCE scores from 312 students over three consecutive cohorts were analyzed. Cohorts included 104, 100, and 108 students with 61% trained in tertiary centres (N = 191). Students trained in tertiary centres had a mean MCQE score of 77%. Students from community centres had a mean score of 78%. There was no significant difference in MCQE scores between tertiary- and community-trained students (p = 0.6099). The OSCE pass rate was 97% for students trained in tertiary centres and 98% for students trained in community centres. OSCE pass rates were not significantly different between the two groups (p = 0.8145). Conclusion: Despite student perceptions that training in tertiary care EM centres was superior, objective analysis showed that academic and clinical performance were similar regardless of training site.

Introduction: There is currently no protocol for the initiation of extra corporeal cardiopulmonary resuscitation (ECPR) in out of hospital cardiac arrest (OHCA) in Atlantic Canada. Advanced care paramedics (ACPs) perform advanced cardiac life support in the prehospital setting often completing the entire resuscitation on-scene. Implementation of ECPR will present a novel intervention that is only available at the receiving hospital, altering how ACPs manage selected patients. Our objective is to determine if an educational program can improve paramedic identification of ECPR candidates. Methods: An educational program was delivered to paramedics including a short seminar and pocket card coupled with simulations of OHCA cases. A before and after study design using a case-based survey was employed. Paramedics were scored on their ability to correctly identify OHCA patients who met the inclusion criteria for our ECPR protocol. Scores before and after the education delivery were compared using a two tailed t-test. A 6-month follow-up is planned to assess knowledge retention. Qualitative data was also collected from paramedics during simulation to help identify potential barriers to implementation of our protocol in the prehospital setting. Results: Nine advanced care paramedics participated in our educational program. Mean score pre-education was 9.7/16 (61.1%) compared to 14/16 (87.5%) after education delivery. The mean difference between groups was 4.22 (CI = 2.65-5.80, p = 0.0003). There was a significant improvement in the paramedics’ ability to correctly identify ECPR candidates after completing our educational program. Conclusion: Paramedic training through a didactic session coupled with a pocket card and simulation appears to be a feasible method of knowledge translation. 6-month retention data will help ensure knowledge retention is achieved. If successful, this pilot will be expanded to train all paramedics in our prehospital system as we seek to implement an ECPR protocol at our centre.

Introduction: Identification of latent safety threats (LSTs) in the emergency department is an important aspect of quality improvement that can lead to improved patient care. In situ simulation (ISS) takes place in the real clinical environment and multidisciplinary teams can participate in diverse high acuity scenarios to identify LSTs. The purpose of this study is to examine the influence that the profession of the participant (i.e. physician, registered nurse, or respiratory therapist) has on the identification of LSTs during ISS. Methods: Six resuscitation- based adult and pediatric simulated scenarios were developed and delivered to multidisciplinary teams in the Kingston General Hospital ED. Each ISS session consisted of a 10- minute scenario, followed by 3-minutes of individual survey completion and a 7- minute group debrief led by ISS facilitators. An objective assessor recorded LSTs identified during each debrief. Surveys were completed prior to debrief to reduce response bias. Data was collected on participant demographics and perceived LSTs classified in the following categories: medication; equipment; resources and staffing; teamwork and communication; or other. Two reviewers evaluated survey responses and debrief notes to formulate a list of unique LSTs across scenarios and professions. The overall number and type of LSTs from surveys was identified and stratified by health care provider. Results: Thirteen ISS sessions were conducted with a total of 59 participants. Thirty- four unique LSTs (8 medication, 15 equipment, 5 resource, 4 communication, and 2 miscellaneous issues) were identified from surveys and debrief notes. Overall, MDs (n = 12) reported 19 LSTss (n = 41) reported 77 LSTs, and RTs (n = 6) reported 4 LSTs based on individual survey data. The most commonly identified category of LSTs reported by MDs (36.8%) and RTs (75%) was equipment issues while RNs most commonly identified medication issues (36.4%). Participants with □5 years of experience in their profession, on average identified more LSTs in surveys than participants with >5 years experience (1.9 LSTs vs 1.5 LSTs respectively). Conclusion: Nursing staff identified the highest number of LSTs across all categories. There was fairly unanimous identification of major LSTs across professions, however each profession did identify unique perspectives on LSTs in survey responses. ISS programs with the purpose of LST identification would benefit from multidisciplinary participation.

Introduction: Current data on utilization of CT imaging point to a trend of increasing overutilization of CT Angiography for the diagnosis of pulmonary embolism (CTPA) over time. Multiple educational and institution-wide interventions addressing this overutilization have been proposed, implemented and evaluated, with mixed results in terms of long-term impact on physician ordering behaviour. The objective of this study is to examine the inter-physician variability in ordering rates and diagnostic yield of CTPA, under a working hypothesis that a small number of physicians are responsible for a disproportionately high number of CTPA ordered in the ED. Methods: Data was collected on all CTPA studies ordered by ED physicians at two very high volume community hospitals and an affiliated urgent care centre during the 2-year period between January 1, 2016 and December 31, 2017. Analysis was limited to those ED physicians who had a total of greater than 500 ED visits over the course of the 2-year period. For each physician, two calculations were made: 1) CT PE ordering rate (total number of CTPA ordered divided by the total number of ED visits), and 2) CTPA diagnostic yield (total number of CTPA positive for PE divided by the total number CTPA ordered). Additional analysis was carried out in order to identify the highest orderers of CTPA and their diagnostic yield. Results: A total of 2,789 CTPA were ordered by 84 physicians for 461,045 total ED visits. Preliminary results show a great deal of variation in ordering rates, ranging from 0.9 to 22.2 CTPA per 1000 ED visit (median = 4.8, IQR = 4.5). Similarly, there was high variation in CT PE yield, ranging from 0% to 50% (median = 9.6%, IQR = 13.1%). Those physicians in the top quartile for ordering rate had a lower mean diagnostic yield, when compared to the lower quartiles (8.9% when compared to 11.5%, 11.9% and 18.2% for the physicians in the third, second, and first quartile respectively). Conclusion: The findings of this study indicate a wide degree of variability in CTPA ordering patterns and diagnostic yield among physicians working within the same clinical environment. There is some suggestion that those physicians who order disproportionately higher numbers of CTPAs have lower diagnostic yields. However, the more interesting lessons from this initial study center on the challenges in creating an audit-and-feedback program targeting CTPA ‘overutilizers’.

Introduction: Emergency Departments are a common point of access for survivors of sexual and gender-based violence (SGBV), but very little is known about where survivors live and the characteristics of the neighbourhoods. The objective of this study was to use hospital-based data to characterize sexual and domestic assault cases and identify geographic distribution across the Ottawa-Gatineau area. Methods: Data for this study were extracted from the Sexual Assault and Partner Abuse Care Program (SAPACP) case registry (Jan 1-Dec 31, 2015) at The Ottawa Hospital. Spatial analyses were conducted using 6-digit postal codes converted to Canadian Census Tracts to identify potential geographic areas where SGBV cases are clustered. Hot-spots were defined as Census Tracts with seven or more assaults within a single calendar year.Data for this study were extracted from the Sexual Assault and Partner Abuse Care Program (SAPACP) case registry (Jan 1-Dec 31, 2015) at The Ottawa Hospital. Spatial analyses were conducted using 6-digit postal codes converted to Canadian Census Tracts to identify potential geographic areas where SGBV cases are clustered. Hot-spots were defined as Census Tracts with seven or more assaults within a single calendar year. Results: In 2015, there were 406 patients seen at the SAPACP, 348 had valid postal codes from Ottawa-Gatineau and were included in the analyses. Over 90% of patients were female and 152 (43.68%) were below 24 years of age. Eight hot-spots were identified including 3 in the downtown entertainment district, 3 lower income areas, 1 high income neighbourhood, and 1 suburb more than 20km from downtown. Conclusion: This study is of the first to use hospital-based data to examine the geographic distribution of SGBV cases, with key findings including the identification of high-income neighbourhoods and suburbs as SGBV hot-spots. Alongside efforts like the #MeToo movement, this evidence challenges stereotypes of assault survivors and highlights the breadth and widespread nature of SGBV.

Introduction: One in nine (11.7%) people in Saskatchewan identifies as First Nations. In Canada, First Nations people experience a higher burden of cardiovascular disease when compared to the general population, but it is unknown whether they have different outcomes in out of hospital cardiac arrest (OHCA). Methods: We reviewed pre-hospital and inpatient records of patients sustaining an OHCA between January 1st, 2015 and December 31st, 2017. The population consisted of patients aged 18 years or older with OHCA of presumed cardiac origin occurring in the catchment area of Saskatoon's EMS service. Variables of interest included, age, gender, First Nations status (as identified by treaty number), EMS response times, bystander CPR, and shockable rhythm. Outcomes of interest included return of spontaneous circulation (ROSC), survival to hospital admission, and survival to hospital discharge. Results: In all, 372 patients sustained OHCA, of which 27 were identified as First Nations. First Nations patients with OHCA tended to be significantly younger (mean age 46 years vs. 65 years, p < 0.0001) and had shorter EMS response times (median times 5.3 minutes vs. 6.2 minutes, p = 0.01). There were no differences between First Nations and non-First Nations patients in terms of incidence of shockable rhythms (24% vs. 26%, p = 0.80), ROSC (42% vs. 41%, p = 0.87), survival to admission (27% vs 33%, p = 0.53), and survival to hospital discharge (15% vs. 12%, p = 0.54). Conclusion: In Saskatoon, First Nations patients sustaining OHCA appear to have similar survival rates when compared with non-First Nations patients, suggesting similar baseline care. Interestingly, First Nations patients sustaining OHCA were significantly younger than their non-First Nations counterparts. This may reflect a higher burden of cardiovascular disease, suggesting a need improved prevention strategies.

Introduction: Procedural sedation in the emergency department (ED) for children undergoing painful procedures is common practice, however little is known about sedation in very young children. We examined the effect of young age on sedation outcomes. Methods: This is a secondary analysis of an observational cohort study of children 0-18 years undergoing procedural sedation in six pediatric EDs across Canada. We compared presedation state, indication for sedation, medications, sedation efficacy and four main post-sedation outcomes (serious adverse events (SAE), significant interventions, oxygen desaturation and vomiting) between patients who ≤2 years with those >2 years. Pre-sedation state, medications, indication for sedation and time intervals were summarized using frequency and percentage and compared with chi2 test. Logistic regression was used to examine associations between age group and outcomes. Results: 6295 patients were included; 5349 (85%) were >2 years and 946 (15%) were ≤2 years. Children ≤2 years were sedated most commonly for laceration repair (n = 450; 47.6%), orthopedic reduction (165; 17.4%) and abscess incision and drainage (136; 14.4%). Children >2years were sedated most commonly for orthopedic reductions (3983; 74.5%). Ketamine was the most common medication in both groups, but was used most frequently in children ≤2 years (80.9% vs 58.9%; p < 0.001). There was no difference in the incidence of SAE, significant interventions or oxygen desaturation between age groups, however children ≤2 years were less likely to vomit (Table 1). Young children had decreased odds of a successful sedation (OR 0.48; 95%CI: 0.37 to 0.63). On average, patients ≤2 years were sedated for 7 minutes less (74.1 vs 81.0 p < 0.001) and discharged 10 minutes sooner (90.1 vs 100.8 p < 0.001). Table 1 ≤2 years (n = 946) >2 years (n = 5349) OR (95%CI)* p-value n(%) n(%) Serious Adverse Event 8 (0.85) 59 (1.0) 0.76 (0.43-1.7) 0.477 Significant intervention 10 (1.0) 76 (1.4) 0.74 (0.34-1.4) 0.374 Oxygen Desaturation 50 (5.3) 303 (5.6) 0.93 (0.67-1.3) 0.640 Vomiting 14 (1.5) 314 (5.9) 0.24 0.13-0.41) <0.001 *Reference category: ≤2 years. Conclusion: Children ≤2 years most commonly received ED sedation for laceration repair using ketamine. Young age was not associated with a significant difference in SAEs, significant intervention or desaturation but was associated with decreased odds of vomiting and of successful sedation.

Introduction: Procedural skills are a key component of an emergency physician's practice. The Edmonton Zone is a health region that comprises eleven tertiary, urban community and rural community emergency departments (EDs) that represents over three hundred emergency physicians. We report the initial stakeholder and site leadership needs assessment used to inform the development of a comprehensive continuing professional development (CPD) procedural skills curriculum for the Edmonton Zone. Methods: A list of procedural skills was distributed to the two Edmonton Zone Clinical Department Heads of Emergency Medicine (EM). This list was based on a previous Canadian study that utilized procedures from the Objectives of Training in EM. Based on perceived needs, twenty-five procedures were chosen by consensus from zone leadership and study authors as the initial focus for a skills curriculum. This list was sent via survey to the physician site leads of all EDs in the zone. Each site lead was asked to indicate the fifteen procedure curriculum they felt would most benefit their respective physician groups. Responses were collated to look at all departments as a group and stratified by the type of ED (tertiary, urban and rural community). Results: Every site chief of Edmonton Zone EDs completed the survey (100% response rate). Cricothyrotomy and pediatric intubation were the two procedures prioritized by every site. One procedure (ultrasound guided central lines) was prioritized by 10/11 sites while three procedures (ultrasound guided central lines, adult intubation and chest tube insertion) were specified by 9/11 sites as needs. Two procedures (pericardiocentesis and thoracotomy) were named as priorities only by tertiary centers. Conversely, three procedures (extensor tendon repair, anterior and posterior nasal packing) were highlighted by all rural sites, but not consistently by any urban sites. Conclusion: Over the next few years, competency-based CPD will emerge for physicians in practice. Our preliminary needs assessment showed that while a common zone-wide curriculum will be possible, targeted curricula tailored to the unique needs of the various types of EDs will also be necessary. This has implications for the resources and teaching requirements needed to deliver effective and recurring CPD courses to an entire health region. A targeted needs assessment to all Edmonton Zone physicians will be the next step to verify and further elaborate on these preliminary results.

Introduction: The geriatric patient population accounts for an ever increasing proportion of emergency department (ED) visits. Geriatric centered EDs are an emerging area of interest and research. Though there have been past studies looking at older patient presentations at individual hospitals, there is limited data describing geriatric presentations within an entire Canadian geographic health region. This study characterizes the population of older adults utilizing the EDs in the Edmonton Zone, a health region that comprises a total of eleven tertiary (T), urban community (UC) and rural community (RC) hospitals. Methods: This retrospective cross-sectional study targeted all patients ≥65 years presenting to the Edmonton Zone EDs between April 1, 2017 to March 31, 2018. Data was extracted from the Emergency Department Information System (EDIS) database for ten EDs in the health region. Clinical and administrative data points were extracted and examined for each site. Results: We analyzed 100,813 ED geriatric patient visits during our study period, accounting for 18.7% of total ED visits to the Edmonton Zone. The five most common triage complaints at ED presentation were shortness of breath, abdominal pain, chest pain with cardiac features, general weakness, and back pain. CTAS scores 1-3 were assigned to 77.8% of geriatric presentations (T: 86.3%, UC: 77.4%, RC: 60.9%). 27.3% of geriatric patients had presented to an ED within the past 30 days (T: 30.0%, UC: 25.4%, RC: 27.7%). On average, 35.3% of older adult ED visits involved a consultation (T: 51.7%, UC 30.8%, RC 14.6%) and approximately 25% of geriatric patients were admitted to hospital during their ED visit (T: 42.8%, UC: 19.4%, RC: 7.1%). The average length of stay (LOS) in the ED (hh:mm) was 10:19 (T: 10:24, UC: 11:38, RC: 5:43). Overall, 2.4% of all geriatric patients left an ED without being seen after initial registration (T: 2.7%, UC: 2.2%, RC: 2.1%). Conclusion: Older adults represent a significant proportion of the ED visits in the Edmonton Zone. The triage acuity, LOS, re-presentation, consultation and admission rates varied based on the type of ED, which has implications for resource allocation within the health region. Our results can also direct future targeted initiatives and quality improvement projects to the various types of EDs in the Edmonton Zone, and facilitate planning of ED services for older adults in other health regions who have a similar geographic distribution of care sites.

Introduction: Patients with neurologic chief complaints comprised 12.5% of total visits to the University of Alberta Emergency Department (ED) in 2017. Symptoms are often subjective, transient, or atypical, leading to diagnostic uncertainty. Serious diagnoses require timely intervention to mitigate morbidity and mortality, however the proportion of patients who leave the ED without being seen (LWBS) has increased over time. We sought to analyze the characteristics and outcomes of patients with neurologic complaints who LWBS to identify opportunities for improvement in quality and safety of patient care. Methods: Data was extracted from the Emergency Department Information System (EDIS) and National Ambulatory Care Reporting System database to select adult patients presenting to the University of Alberta Hospital in 2017 with neurologic complaints as defined by the Canadian Triage Acuity Scale (CTAS). Using standard descriptive statistics we examined demographic and clinical characteristics to compare LWBS patients to all others. Results: Of 8,726 total visits 7.54% patients LWBS. These patients tended to be younger on average (39 vs 55 years), with a larger proportion presenting at night (37.69%) and on Monday. The majority were triaged CTAS 3 (68.69%). Their mean length of stay was shorter than all other visits (3.70 vs 9.51 hours). Headache (22.74%), extremity weakness/symptoms of CVA (20.19%), head injury (14.32%), seizure (8.28%), and sensory loss/paresthesia (8.14%) comprised the top 5 neurologic complaints, and were disproportionately presented in LWBS patients; headache (31.76%), head injury (23.71%), sensory loss/paresthesia (12.01%), seizure (11.25%). Patients who LWBS also re-presented to the ED within 72 hours (21.43%), more often than those discharged by a physician (8.29%). Conclusion: Patients presenting with neurologic complaints who LWBS are younger, tend to arrive at night, with less acute presentations, however they more frequently return to the ED within 72 hours than those seen and discharged. Patients who LWBS may benefit from education, physician assessment or closer nurse reassessment at triage to increase the quality and safety of care in the ED, reduce return visits and ED utilization.

Introduction: Patients with neurologic presenting complaints comprised 12.5% of total University of Alberta Emergency Department (ED) visits in 2017. This group of patients has high rates of EMS utilization, admission, and ED resources including diagnostic imaging and consult services. We sought to analyze the characteristics and outcomes of the patients with neurologic complaints who have an unscheduled return visit (URV) to the ED within 72 hours to identify opportunities for improvement in quality and safety of patient care. Methods: Data was extracted from the Emergency Department Information System (EDIS) and National Ambulatory Care System databases to select adult patients presenting to the University of Alberta hospital in 2017 with neurologic complaints as defined by the Canadian Triage and Acuity Scale (CTAS). We additionally selected for return visits to Edmonton Zone EDs within 72 hours. Using standard descriptive statistics, we examined demographic and clinical characteristics of patients with 72-hour URV. Results: Of 8,770 total visits, 674 (7.69%) had a 72-hour URV to an Edmonton zone ED. The URV rate was 9.0% in patients seen by a physician and discharged with approval and 23.4-33.3% in patients who left against medical advice (LAMA), prior to completion of treatment (LPCT), or without being seen by a physician (LWBS). The mean age of URV patients was 45.6 years, 56.5% were male, with a mean ED length of stay of 7.37 hours. The top 5 diagnoses for URV patients were headache, migraine, alcohol related disorders, concussion, and transient ischemic attack. 14.7% of URV patients were admitted, 13.5% LWBS, 1.6% LAMA, 1.6% LPCT, and 66.1% were discharged. Conclusion: The majority of neurologic complaint patients with URV within 72 hours are those who LAMA, LPTC, or LWBS at index visit. The admission rate for URV patients (14.7%) is lower than for the index ED visit (55%), however these patients have high LWBS rates. Identifying strategies to limit the LWBS rate for these patients would reduce return visits and improve the quality and safety of patient care.

Introduction: Evidence suggests that prehospital point of care ultrasound (POCUS) may improve outcomes. It serves as an aid in physical examination, triage, diagnosis, and patient disposition. The rate of adoption of POCUS among aeromedical services (AMS) throughout Canada is unknown. The objective of this study was to describe current POCUS use among Canadian AMS providers. Methods: This is a cross-sectional observational study. A survey was emailed to directors of government-funded AMS bases in Canada. Data was analyzed using descriptive statistics. Results: The response rate was 88.2% (15/17 AMS directors) and accounted for 42 out of 46 individual bases. POCUS is used by AMS in British Columbia, Alberta, Saskatchewan, and Manitoba. New Brunswick, Nova Scotia, Prince Edward Island, and Yukon are planning to introduce POCUS within the next year. Ontario, Quebec, and Newfoundland are not utilizing POCUS and are not planning to introduce it. BC is the only province currently using POCUS on fixed-wing aircraft. POCUS is used in <25% of missions, most frequently at sending hospital and in flight. Most useful applications were assessment for pneumothorax, free abdominal fluid, and cardiac standstill. Most common barrier to POCUS use was cost of training and maintenance of competence. Conclusion: Prehospital POCUS is available in Western Canada with one third of the Canadian population having access to AMS utilizing ultrasound. The Maritimes and the Yukon Territory will further extend POCUS use on fixed-wing aircraft. While there are barriers to POCUS use, those bases that have adopted POCUS consider it valuable.

Introduction: For many years, Emergency Medicine (EM) educators have used narrative comments to assess their learners on each shift, either in isolation or combined with some type of Likert scale ranking. Competency based medical education (CBME), soon to be fully implemented throughout Canadian EM educational programs, encourages this type of frequent low-stakes narrative assessment. It is important to understand what information is currently garnered from existing narrative assessments in order to successfully and smoothly transition to the CBME system. The purpose of this study was to explore how one Canadian undergraduate EM program's narrative assessment comments mapped to two competency frameworks: one traditional CanMEDS-based and one competency-based, built on entrustable professional activities (EPAs). Methods: A qualitative and quantitative content analysis of 1925 retrospective, narrative assessments was conducted for the 2015/2016 and 2016/2017 academic years. The unprompted comments were mapped to the Royal College CanMEDS framework and the Association of Faculties of Medicine of Canada EPA Framework. Using an iterative coding process as per accepted qualitative methodologies, additional codes were generated to classify comments and identify themes that were not captured by either framework. Results: 93% and 85% of the unprompted narrative assessments contained comments that mapped to at least one CanMEDS role or EPA competency, respectively. The most common CanMEDS role commented upon was Medical Expert (86%), followed by Communicator, Collaborator and Scholar (all at 23%). The most common EPA competency mentioned related to history and physical findings (62%) followed by management plan (33%), and differential diagnosis (33%). However, 75% of narrative comments contained within the assessments, included ideas that did not fall into either framework but were repeated with frequency to suggest importance. The experiential characteristics of working with a learner were commented upon by 22% of preceptors. Other unmapped themes included contextual information, generalities and platitudes, and directed feedback for next steps to improve. Conclusion: While much of the currently captured data can be mapped to established frameworks, important information for both learner and assessor may be lost by limiting comments to the competencies described within a particular framework, suggesting caution when transitioning to a CBME assessment program.

Introduction: Iron Deficiency Anemia (IDA) is a common presentation to the emergency department (ED) and is often treated with red blood cell transfusions. Choosing Wisely and the American Association of Blood Banks released guidelines in 2016 outlining under what circumstances transfusions should be given for patients with IDA. Few well-powered studies have looked at the impact of these guidelines on transfusions in EDs. The goal of this study was to examine the number of RBC transfusions that were given in EDs in Calgary, Alberta from 2014-2018 and what proportion of these were potentially avoidable (PA). Methods: We analyzed 8651 IDA patient encounters from 2014–2018 at four centers in the Calgary Zone. A transfusion was considered PA if the patient's hemoglobin (hgb) was ≥70 g/L AND if the patient was hemodynamically stable. We performed descriptive statistics to assess the number of transfusions and the number of avoidable transfusions. We used chi-squared tests to determine if there were significant differences between site, time-period, hemoglobin level. Results: In total, 990 (11.4%) of the encounters received transfusions; 711 (71.8%) were indicated while 279 (28.1%) were PA. Out of the transfusions that were indicated, 230 (32.3%) were given to patients with a hgb <70 g/L and 481 (67.7%) were given to patients with a hgb >70 g/L but who were hemodynamically unstable. Out of the transfusions that were PA, the highest number were given to those in the 71-80 g/L hgb group (142) and the lowest number were given to those in the 110-130 g/L hgb group (9), a difference that was statistically significant (p < 0.001). The PA transfusion rates from 2014 to 2018 were 30.8%, 25.6%, 34.5%, 23.6%, 20.7% respectively, which was a statistically significant difference (p = 0.004). Conclusion: Our data suggest that the number of PA transfusions at the hospitals in the Calgary zone is comparable to the rates reported in the existing literature. In addition, the rate of PA transfusions has decreased since the release of the guidelines. A limitation of the present study was that it did not look at the number of units of red blood cells transfused and since many patients receive more than one unit, it is possible that the number of PA transfusions was underestimated. Nevertheless, we intend to use our results to create a safer and more cost-effective approach to managing IDA.

Introduction: Global health partnerships (GHPs) between high income and low income countries are a means of capacity building in education. Literature often focuses on the GHP structure and output, along with retention and experience of local trainees, but neglects the experience of involved faculty. Here, we survey Canadian teaching faculty participating in the Toronto Addis Ababa Academic Collaboration in Emergency Medicine (TAAAC-EM) to describe characteristics of participants and their experience in the program. Methods: EM faculty participating in TAAAC-EM teaching trips from 2011-2016 were invited to complete an online survey in February 2017. Teaching faculty travel for one month and undergo an extensive selection process, pre-departure training and post-trip debriefing. Quantitative and qualitative data were collected and analyzed using basic statistics and inductive thematic analyses respectively. Results: Overall, 19 (N = 30, 63.3%) faculty completed the survey, of which 13 had prior global health experiences (range 1 to > 12 months). On a scale of 1-7, participants rated their mean overall experience as a 5.9 and preparation as a 5.7. Among respondents, 79% would participate in future TAAAC-EM activities, 79% would engage in future global health endeavours, 95% said the experience improved their satisfaction of practicing clinical medicine and 89% said it improved their enjoyment of teaching medicine. However, while 58% stated they would recommend this experience without hesitation to colleagues, the remaining 42% said they would recommend this experience with caveats. This latter group had a lower rated preparedness (MD = 1.398, p = 0.003) and TAAAC-EM experience (MD = 1.545, p = 0.001). Major themes in qualitative responses included that the participants felt that intrinsic motivation and flexible predispositions were necessary to participate. Intrinsic motivation for global health involvement included appreciation and impact for GH, and personal growth. Regarding flexibility, respondents highlighted the importance of having a flexible demeanor to understand, accommodate and ethically address cultural differences and practicing in another context. Conclusion: The type of faculty to recruit for GHPs may require flexible predispositions and intrinsic motivation for GH. These qualities combined with adequate preparation can facilitate overall faculty experiences on global health trips.

Introduction: In July 2018, Emergency Medicine (EM) transitioned to the Royal College of Physicians and Surgeons of Canada's (RCPSC) Competence by Design (CBD) training framework. In anticipation of CBD implementation, we conducted a nation-wide needs assessment of EM faculty and senior residents to understand their attitudes towards CBD, workplace-based assessments (WBA) and overall educational needs. Methods: A multi-site, cross-sectional digital survey was conducted in winter 2018 with a sample of EM faculty and senior residents across RCPSC EM programs in Canada. Recruitment was via program director nomination. Survey domains included baseline perceptions about CBD, attitudes toward implementation, perceived/prompted and unperceived faculty development needs. Microsoft Excel was used to calculate descriptive statistics. This study was reviewed by the Hamilton Integrated Research Ethics Board.A multi-site, cross-sectional digital survey was conducted in winter 2018 with a sample of EM faculty and senior residents across RCPSC EM programs in Canada. Recruitment was via program director nomination. Survey domains included baseline perceptions about CBD, attitudes toward implementation, perceived/prompted and unperceived faculty development needs. Microsoft Excel was used to calculate descriptive statistics. This study was reviewed by the Hamilton Integrated Research Ethics Board. Results: Between February-April 2018, 47 participants (40 faculty, 7 residents) completed the survey (58.8% response rate). Most respondents (89.4%) thought learner feedback should be provided on each shift; 55.3% believed they provided adequate feedback. Time constraints, learner disinterest and fear of assessment repercussions were the top three barriers to providing good feedback. A majority of respondents (78.7%) thought that the ED provided above average opportunities for direct observation and 91.5% were confident of incorporating WBAs into their practice. 44.7% reported that CBD will not impact patient care; 17.0% perceived it may have a negative impact. 55.3% felt that CBD will lead to improved feedback for trainees. The top areas for faculty development were: feedback delivery, completing WBAs, resident promotion decisions, and receiving feedback on teaching. Only 25.5% were interested in learning about CBD, although the average of correct responses on the CBD knowledge test was 44.6%. Conclusion: EM is well-situated to transition to CBD given clinicians’ positive attitudes towards feedback, direct observation, WBAs, and opportunities for direct observation. Threats to CBD implementation are concerns about effects on patient care and trainee education, and skepticism regarding effects on feedback quality. Faculty development should concentrate on further developing clinical teaching and supervision skills, focusing on feedback and WBAs.

Introduction: Today's emergency department sees healthcare system pressures manifest through longer wait times, increased costs, and provider burnout. In the face of questionable sustainability, there is a greater role for training future innovators and entrepreneurs in healthcare. However, there is currently little formal education or mentorship in these areas. The aim of this scoping review was to identify the current and ideal educational practices to foster innovative and entrepreneurial mindsets, with specific interest amongst emergency medicine trainees. Methods: Using a scoping review methodology, the relationship between healthcare and entrepreneurship was explored. OVID, PubMed and Google Scholar were searched using the keywords “entrepreneurship”, “health education” and “health personnel”, on March 8th, 2018. Results were screened by title, abstract and full text by a team of three calibrated researchers, based upon pre-defined exclusion and inclusion criteria. The final list of papers was reviewed using an extraction tool to identify demographics, details of the paper, and its attitudes and perceptions towards entrepreneurship and innovation. Results: After screening, 59 papers were identified for qualitative analysis. These papers ranged from 1970-2018, mainly from the USA (n = 36). Most papers were commentaries/opinions (n = 35); 11 papers described specific innovations. Entrepreneurship was viewed positively in 45 papers, negatively in 2 papers, and mixed in 12 papers. Common specialties discussed were surgery (n = 9), internal medicine (n = 3), and not specified (n = 44). Emergency medicine was described in one paper. Major themes were: entrepreneurial environment (n = 29), funding and capital (n = 12), idea generation (n = 9), and teaching entrepreneurship (n = 6). Of the 11 innovation papers, the discussion was focused on educational (n = 6) or system (n = 5) innovations. These innovations related to surgery (n = 1), public health (n = 1) and palliative care (n = 1). None of these innovations were specific to emergency medicine. Conclusion: This review indicates a small number of programs focused on promoting innovation and entrepreneurship amongst trainees, but no programs specific to the emergency department. There may be benefit for educators in emergency medicine to consider how to foster a greater innovative spirit in our speciality, so our next generation of physicians can help tackle problems affecting patient care.
