Innovation Concept: Emergency physicians (EP) rarely receive timely, iterative feedback on clinical performance that aids their reflective practice. The Calgary zone ED recently implemented a novel email-based alert system wherein an EP is notified when a patient whose ED care they were involved in is admitted to hospital within 72-hours of discharge from an index ED visit. Our study sought to evaluate the general acceptability of this form of audit and feedback and determine whether it encourages practice reflection. Methods: This mixed methods realist evaluation consisted of two sequential phases. An initial quantitative phase used data from our electronic health record and a survey to examine the general features and acceptability of 72-hour readmission alerts sent from May 2017-2018. A subsequent qualitative phase involved semi-structured interviews exploring the alert's role in greater depth. Quantitative data were summarized using descriptive statistics and qualitative data were analyzed using thematic and template analysis techniques. Results of both phases were used to guide construction of context-mechanism-outcome statements to refine our program theory. Curriculum, Tool, or Material: 4024 alerts were sent over a 1-year period, with each physician receiving approximately 17 alerts per year (Q1: 7, Q3: 25, IQR: 18). The top five CEDIS complaints on index presentations were abdominal pain, flank pain, shortness of breath, vomiting and/or nausea, and chest pain (cardiac features). The majority of re-admissions (78.6%) occurred within 48 hours after discharge. Immediate alert survey feedback provided by EP's noted that 52.65% (N = 471) of alerts were helpful. Thematic analysis of 17 semi-structured interviews suggests that the alert was generally acceptable to physicians, However, certain EPs were concerned that the alert impacted hire/fire decisions even when leadership didn't endorse this sentiment. Physicians who didn't believe alerts were involved in hire/fire decisions, described greater engagement in the reflective process. Conversely, physicians, who believed alerts were involved in hire/fire decisions, were more likely to defensively change their practice. Conclusion: Most EPs noted that timely notification of 72-hour readmissions made them more mindful of documenting discharge instructions. Our implementation of a 72- hour readmission alert was an acceptable format for audit and feedback and appeared to facilitate physician reflection under certain conditions.

Innovation Concept: The Orange Book (OB) identifies drugs approved on the basis of safety and effectiveness by the FDA and serves as the gold standard reference for correct pharmacological therapies. It ties in closely with Choosing Wisely Canada (CWC) modelling good stewardship in antimicrobial prescriptions. The book focuses on passive didactic learning instead of active learning, which was shown to have a greater influence on prescribing behaviour. Educational video games, a form of active learning, have been shown to improve clinical skills in medical training. Contagion is a role-playing video game providing an active way of teaching antimicrobial components of the OB and CWC guidelines. Method: Phase I of Contagion was qualitatively tested on students and physicians at McMaster University for teaching effectiveness, applicability to real-life scenarios, and enjoyability. Post-game play 12 participants scored different aspects of the game on a Likert scale. Curriculum, Tool, or Material: The player is a rural physician treating infections in various communities. Each round, the player is given a crate of antibiotics. As communities are infected, the player is provided with clinical symptoms the patients present with. The player must identify the pathology and then correctly treat the communities. The player can treat empirically or order tests to identify the infectious organism. The player strategically navigates which communities to treat as there are limited actions per turn and the player must prevent communities from dying or infecting neighboring regions. Communities tend to build antibiotic resistance over time making first-line treatments unviable, thus careful strategizing and stewardship is essential. Active learning will occur when players are tasked with finding the correct answer to different presentations. After each turn, players will learn about the infecting organism, its phenotypes, and common infectious symptoms. This is considered passive learning. Conclusion: Contagion was well-received by physicians and medical students as an active learning tool to teach the OB and CWC guidelines. On preliminary user testing Contagion scored 5 in effectiveness in teaching treatments and 4.6 in teaching stewardship. An objective of this project is to perform large scale testing across schools to demonstrate the effectiveness of the learning components of the game. We hope to eventually create a tool that can be incorporated in continuing medical education for physicians.

Innovation Concept: In Sudbury, ON 44% of out-of-hospital cardiac arrest (OHCA) patients receive bystander CPR (bCPR), and only 4.7% survive cardiac arrest. The Northern City of Heroes (NCH) community initiative was launched in April 2019 with a goal of improving survival from OHCA through hands-only bCPR in the municipality. One NCH initiative is an interactive exhibit at Science North, a science centre in Sudbury that hosts 250,000 visitors annually. The exhibit employs simulation trainers for CPR, accompanying signage and interactive elements. The goals of the exhibit are to activate bCPR, change and measure behaviours through exhibit interactions on how to deliver excellent CPR, and improve survival rates in OHCA patients. Methods: Data is being collected from 3000 visitors using self-reported surveying via SurveyGizmo to assess likelihood of performing bCPR, pre and post interacting with the exhibit. Visitor behaviour will be examined at the exhibit using video-recorded interactions and coding those behaviours using BORIS software. Behavioural data will be analyzed using the Visitor Engagement Framework (VEF) where initiation, transition and breakthrough learning-behaviours are coded and an exhibit Visitor Engagement Profile (VEP) is created. The VEF and VEP are tools used in informal learning settings to assess exhibit impacts on learning. Curriculum, Tool, or Material: The use of an easily-apprehendable, hands-on exhibit tool located in a public setting, such as a science centre, creates a platform for engaging large and diverse public audiences. This type of bCPR exhibitry has not been implemented in other similar environments. The informal learning setting allows the science centre staff to engage in personalized interactions that can solidify the quality of learning and confidence in employing the new skills developed. Conclusion: The NCH exhibit and new strategies for embedding informal curriculum are powerful tools to reach diverse audiences, build knowledge and skills, and have a measurable impact on bCPR and OHCA survival rates. Data is being captured and tracked by Health Sciences North around the City of Greater Sudbury's bCPR and OHCA survival rates to monitor long-term impacts of the NCH community initiatives. Limitations of the study may be found in the focused demographics as well as the nature of self-reported learning. Future research directions include broader geographical surveying to assess improvements in community response to OHCA as a direct result of an interactive bCPR exhibitry.

Innovation Concept: Advocacy is a key competency of Canadian residency education, yet physicians seldom engage with supra-clinical advocacy efforts upon completion of training. Emergency medicine (EM) residency training may not equip graduates with the knowledge and skills required to engage as physician-advocates in their communities. Focused writing workshops may increase the confidence and ability of EM trainees to engage as health advocates. Methods: Following a literature review, simulated newsroom workshops were developed by two EM physicians with graduate-level journalism training and workplace experience. Participants were invited to participate in an audio-recorded focus-group and to submit their opinion editorial. Twelve participants registered for the workshops and six attended both sessions and the focus group; four submitted written work. Focus group transcripts and written work were qualitatively analysed to understand acceptability, feasibility, and how students might engage as future health advocates. Curriculum, Tool, or Material: The simulated newsroom consisted of participants acting as journalists and the expert facilitator acting as a news editor. The first workshop provided a framework for news judgement in a didactic session, followed by interactive exercises including: prioritization of news pitches, a simulated editorial meeting, and analysis of published news articles. The participants then drafted their own pitches for in situ feedback from peers and facilitators. Two-weeks later, participants brought their completed articles for peer and expert review before submitting their final article. Conclusion: The innovation bolstered resident physician confidence in advocacy through the popular press, and provided demonstrable skills in opinion writing. Participants felt challenged to develop compelling narratives and differentiate this form of advocacy communication from academic writing or prior media training. Participants valued the workshop as a voluntary component of residency education led by peer experts. Through their writing, residents demonstrated an understanding of structural factors that impact patient health and health systems. Future engagement as physician advocates may be tempered by fears of professional repercussions for public engagement; the impact of physician advocacy on population health outcomes is not yet known.

Innovation Concept: EM Sim Cases is an innovative, open-access website that was created in 2015 to publish medical simulation resources including standardized, peer-reviewed simulation cases. Herein we describe our interim analysis. Methods: We performed a massive online needs assessment using a methodology previously described by Chan et. al. to determine how we can shape EM Sim Cases to meet the needs of learners and educators who use it. We engaged with simulation experts from the Emergency Medicine Simulation Education Research Collaborative to design a Google Forms survey using best practices in survey design. We distributed the survey to our target community of practice via Twitter, email, and a blog post published on emsimcases.com. Curriculum, Tool, or Material: We received 81 responses from simulation educators representing 8 medical specialties and 13 countries. Most survey respondents identified themselves as staff physicians (n = 44) and specialized in emergency medicine (n = 39). They had 0-21+ years of experience. 37% of respondents (n = 30) stated that material from EM Sim Cases makes up 25% or more of their simulation curriculum. Several respondents noted that using this content made them feel more confident and more current. Respondents praised EM Sim Cases for a well-organized case format, the proper level of detail, consistency between case designs, and the wide variety of cases. Suggested improvements included an opportunity to directly comment on cases and more cases in pediatric, rural, and advanced airway management situations. Suggestions were made to improve the navigability of the website. Respondents wanted to see additional blog content on debriefing strategies and self-made task/skill trainers. Conclusion: EM Sim Cases is a novel, free open-access simulation resource. Using a massive online needs assessment we were able to determine future directions including case topics, website reorganization, and educational material. We were also able to capture how impactful a resource like this can be to clinical and educational practice outside of the simulation setting.

Innovation Concept: High-acuity, low-occurrence (HALO) procedures require skilled performance as they treat life-threatening conditions and are associated with significant morbidity when performed incorrectly. Simulation has proven useful for deliberate practice in a low stake setting. Tube thoracostomy is amendable to this approach. Commercially available trainers exist but often have limited realism and are prohibitively expensive particularly to non-academic centers. Three-dimensional (3D) printing produces models suitable for simulation, but no current simulator has been developed and validated for tube thoracostomy. The aim of this study was to develop such, a 3D-printed low-fidelity simulator validated for the simulation-based instruction of tube thoracostomy. Methods: The development of the simulator followed an iterative design cycle with collaboration between a design team and an emergency medicine expert. Its validity (face and content) was tested through hands-on practice and surveys completed by 15 acute-care practitioners. Participants performed the procedure on the simulator and then provided feedback through a mixed quantitative/qualitative product evaluation survey on appearance, realism (face validity) and value in procedural training (content validity). Mean values for overall appearance and content validity as a training tool were 4/5 and 4.3/5 respectively. All respondents felt the model was a useful adjunct. All but one stated it was a good replacement for pre-existing trainers. Curriculum, Tool, or Material: The model was initially printed in three parts using an Ultimaker 3 and Axiom Airwolf Dual 3D-printer. The ribcage was created using polylactic acid with polyvinyl alcohol support material. Printed sections were bonded using glue at interfaces requiring no flexibility. Flexible joints were made of varying amounts of thermoplastic polyurethane and thermoplastic elastomer. Skin overlay for the whole model was created with a cut out area for replaceable sections that subjects would incise to insert the chest tube. Skin was casted using platinum cured silicone in a 3D-printed mold. Total cost of all materials was roughly 80 CAD. Conclusion: The simulator was found to be a useful adjunct for the simulation-based practice of tube thoracostomy. As well, users found the model anatomically realistic and avoided high-cost and ethical issues. Further research will focus on optimization based on feedback and development into a multi-functional simulator for other HALO procedures.

Innovation Concept: The Calgary Audit and Feedback Framework (CAFF) is an innovative tool developed by the Physician Learning Program (PLP). By addressing four key factors –relationships, question choice, data visualization, and facilitation – CAFF addresses common barriers to physicians receiving their practice data. The goal of this study is to assess whether CAFF-facilitated physician performance improvement (PPI) sessions: 1) improve physicians’ receptiveness to their practice data, and 2) encourage physicians to both identify opportunities for practice change and create action plans. Methods: Peer facilitators were trained to facilitate PPI sessions using the CAFF model. In Calgary, 51/180 emergency physicians have attended at least one of the six PPI sessions. The sessions were evaluated using surveys, commitment to change forms, and the Feedback Orientation Scale (FOS). The FOS is a scale developed to measure a participant's orientation to performance feedback across the four domains of utility, accountability, social awareness, and feedback self-efficacy. Curriculum, Tool, or Material: The PLP has developed and implemented CAFF as a framework to help foster socially constructed learning in audit and group feedback sessions. The CAFF model ensures that the aforementioned four key factors are considered for design and implementation of audit and group feedback. The PLP found that establishing the meaning and credibility of the data is a necessary precursor to reflection and action planning. Conclusion: The FOS was completed for 25/32 physicians. The mean FOS score improved by 0.339 (p < 0.001; z=−3.863). While the mean scores all four domains increased, ‘Feedback Self-Efficacy’ increased the most by .0620 (p < 0.001; z=−3.999). Participants reported that examples of changes made by the peer facilitators were particularly helpful. Evaluations from the sessions suggested physicians overwhelmingly agreed or strongly agreed that the peer comparison was valuable, that the reports helped them reflect on their practice, and that the session helped them identify learning opportunities and strategies to change their practice.

Background: Traditionally, radiologists have routinely recommended oral contrast agents (such as Telebrix®) for patients undergoing a computed tomography of the abdomen/pelvis (CTAP), but recent evidence has shown limited diagnostic benefits for most emergency department (ED) patients. Additionally, the use of oral contrast has numerous drawbacks, including patient nausea/vomiting, risk of aspiration and delays to CTAP completion and increased ED length of stay (LOS). Aim Statement: The aim was to safely reduce the number of ED patients receiving oral contrast prior to undergoing CTAP and thereby reduce ED length of stay. Measures & Design: An evidence-based ED protocol was developed in collaboration with radiology. PDSA cycle #1 was implementation at a pilot site to identify potential barriers. Challenges identified included the need to change the electronic order sets to reflect the new protocol, improved communication with frontline providers and addition of an online BMI calculator. PDSA cycle #2 was widespread implementation across all 4 ED's in the Calgary zone. The protocol was incorporated into all relevant electronic ED order sets to act as a physician prompt. Using administrative data, we extracted and analyzed data using descriptive and inferential statistics for the outcomes and balancing measures from a period of 12 months pre- and 12 months post-intervention. Evaluation/Results: A total of 14,868 and 17,995 CTAP exams were included in the pre and post periods, respectively. There was a reduction in usage of oral contrast from 71% to 30% (P < 0.0001) in the pre- and post-study period, respectively. This corresponded to a reduction in average time of CT requisition to CT report completed from 3.30 hours to 2.31 hours (-0.99 hrs, P = 0.001) and a reduction in average ED LOS from 11.01 hours to 9.92 hours (-1.08 hrs, P < 0.0001). The protocol resulted in a reduction of 19,434.6 patient hrs in the ED. Run charts demonstrate change was sustained over time. Our protocol did not demonstrate an increase in rates of repeat CTAP (P = 0.563) at 30 days, nor an increase in patient re-admission within 7 days (P = 0.295). Discussion/Impact: Successful implementation of an ED and radiology developed protocol significantly reduced the use of oral contrast in patients requiring enhanced CTAP as part of their diagnostic work up and, thereby, reduced overall ED LOS without increasing the need for repeat examinations within 30 days or re-admission within 7 days.

Background: Ketorolac has long been used to manage pain in the Emergency Department and has the advantage of being the only parenteral NSAID formulation. Despite multiple studies demonstrating an analgesic ceiling dose of 10mg for intravenous ketorolac, higher doses (30-60mg) are commonly ordered. Use of optimal doses of ketorolac (10mg) has the advantage of lower side effects and cost. Aim Statement: The aim of this project was to increase the usage of the optimal dose parenteral ketorolac (10mg) without increasing the use of additional, concomitant or rescue opioids (balancing measures). Measures & Design: This pre-/post-intervention comparison study (May 1, 2016 to April 30, 2018) included all patients ≥18 years of age that received parenteral ketorolac at one of 4 EDs in the Calgary zone. All data was captured via administrative data records. Stakeholders (ED leadership, analgesia committee, nursing and pharmacy) provided feedback and support for the project. Our multi-modal intervention included modifying all ED computerized order sets such that the default parenteral ketorolac dose was 10mg (post-intervention) from 30mg (pre-intervention), education (dissemination of evidence to support the changes to clinicians) and our pharmacy securing 10mg vials of ketorolac. At their discretion, physicians’ were still able to order other doses of ketorolac. Evaluation/Results: During the 2 year study period, 19290 patient records were identified where parenteral ketorolac was administered during the ED visit. Baseline characteristics were similar between the pre/post periods. Prior to the change in default dosing, 10.5% of orders were for ketorolac 10mg compared to 87% in the post-intervention period (p < 0.000). Statistical process charts support the above results and demonstrate that the changes have been sustained. There were no differences in patients receiving ketorolac as the only analgesic between the pre/post periods (42% vs 42%, p = 0.396), nor where there significant changes in concomitant opioid usage (46% vs 46%, p = 0.817), or rescue analgesia (11% vs 12%, p = 0.097). Discussion/Impact: In this large cohort, our multi-modal intervention, resulted in a significant increase in optimal ketorolac parenteral dosing without a significant change in additional opioid use. The results support the utility of computerized order set changes as the cornerstone of an effective and rapid knowledge translation strategy to align physician practice with best evidence.

Background: Despite strong evidence recommending supportive care as the mainstay of management for most infants with bronchiolitis, prior studies suggest that many of these patients receive low-value interventions. Providing clinicians with their practice reports and peer comparator data or an achievable benchmark of care (audit and feedback) has been shown to be an effective strategy to improve adherence to guidelines. Aim Statement: To decrease low-value care (use of any or all of chest radiographs, viral testing and salbutamol) in infants with bronchiolitis by delivering individual physician reports in addition to Group Facilitated Feedback Sessions (GFFS) to pediatric emergency physicians (PEPs). Measures & Design: Our cohort included 3,883 patients ≤12 months old that presented to two emergency departments with a diagnosis of bronchiolitis from April 1, 2013 to April 30, 2018. Using administrative data we captured baseline characteristics and interventions. Consenting PEPs received two audit and feedback (A&F) reports which included their individual and peer comparator data. Two multi-disciplinary GFFS (including inpatient pediatricians, nurse, learners and respiratory therapists) presented data and identified barriers and enablers of reducing low-value care. The primary outcome was the proportion of patients who received any low-value intervention, and was analyzed using statistical process control charts. Process measures (consent to obtain report, attendance and evaluations from the feedback session) and balancing measures were also captured. Evaluation/Results: 78% of PEPs consented to receive their A&F reports. Patient baseline characteristics were similar in the baseline (n = 3109) and intervention period (n = 774). Following the baseline physician reports and the GFFS, low-value care decreased from 42.6% to 27.1% (absolute difference: -15.5%; 95% confidence interval (CI): -19.8% to -11.2%) and 78.9% to 64.4% (absolute difference: -14.5%; 95% CI: -21.9% to -7.2%) in patients who were not admitted and admitted, respectively. Balancing measures such as ICU admission (absolute difference: -0.6%; 95%CI: -5.7% to 4.4%) and ED revisit within 72 hours (absolute difference: -0.1%; 95% CI: -3.1% to 3.0% non-admitted patients, 1.0%; 95% CI: -1.2% to 3.2% admitted patients) were unchanged. Discussion/Impact: The combination of audit and feedback and a GFFS significantly reduced low-value care for pediatric patients with bronchiolitis by PEP's.

Background: Since January 1, 2016 2358 people have died from opioid poisoning in Alberta. Buprenorphine/naloxone (bup/nal) is the recommended first line treatment for opioid use disorder (OUD) and this treatment can be initiated in emergency departments and urgent care centres (EDs). Aim Statement: This project aims to spread a quality improvement intervention to all 107 adult EDs in Alberta by March 31, 2020. The intervention supports clinicians to initiate bup/nal for eligible individuals and provide rapid referrals to OUD treatment clinics. Measures & Design: Local ED teams were identified (administrators, clinical nurse educators, physicians and, where available, pharmacists and social workers). Local teams were supported by a provincial project team (project manager, consultant, and five physician leads) through a multi-faceted implementation process using provincial order sets, clinician education products, and patient-facing information. We used administrative ED and pharmacy data to track the number of visits where bup/nal was given in ED, and whether discharged patients continued to fill any opioid agonist treatment (OAT) prescription 30 days after their index ED visit. OUD clinics reported the number of referrals received from EDs and the number attending their first appointment. Patient safety event reports were tracked to identify any unintended negative impacts. Evaluation/Results: We report data from May 15, 2018 (program start) to September 31, 2019. Forty-nine EDs (46% of 107) implemented the program and 22 (45% of 49) reported evaluation data. There were 5385 opioid-related visits to reporting ED sites after program adoption. Bup/nal was given during 832 ED visits (663 unique patients): 7 visits in the 1st quarter the program operated, 55 in the 2nd, 74 in the 3rd, 143 in the 4th, 294 in the 5th, and 255 in the 6th. Among 505 unique discharged patients with 30 day follow up data available 319 (63%) continued to fill any OAT prescription after receiving bup/nal in ED. 16 (70%) of 23 community clinics provided data. EDs referred patients to these clinics 440 times, and 236 referrals (54%) attended their first follow-up appointment. Available data may under-report program impact. 5 patient safety events have been reported, with no harm or minimal harm to the patient. Discussion/Impact: Results demonstrate effective spread and uptake of a standardized provincial ED based early medical intervention program for patients who live with OUD.

Background: In patients with acute hip fracture, a fascia iliaca compartment block (FICB) has been shown to provide effective non-opioid analgesia, reduce the incidence of pneumonia, and potentially decrease the rate of delirium [1]. However, this procedure was infrequently used in the St. Michael's Hospital (SMH) emergency department (ED). Aim Statement: Our aim was to increase the proportion of patients with hip fracture receiving FICB in the ED to 50% in six months. Measures & Design: We completed two Plan-Do-Study-Act (PDSA) cycles, measuring rates of FICB before and after each cycle. The first was a departmental rounds presentation with information about the process and benefits of FICB, addressing barriers identified by surveying the group. The second cycle included a bundle of interventions comprising of an “instruction card” with the steps required to do the procedure, access to a video tutorial, and a list of experienced physicians willing to help less experienced providers perform FICB. Evaluation/Results: In the three months prior to the project, the rate of FICB in the ED was 12.5% (3/24). For the three months after the first PDSA cycle, the rate increased to 22.2% (8/36). Then, the second cycle was performed. In the following two months the rate further increased to 36.8% (7/19). Discussion/Impact: Despite the clear increase in FICB rate, these changes were not statistically significant (p = 0.063). Our methodology was shown to be safe and effective, and our model can be applied to other ED groups looking to increase their rates of FICB.

Background: Liberal prescribing of opioids is a major contributing factor to the opioid crisis. Patients who take opioids for >5 consecutive days are at greater risk of long-term use. Evidence shows that significantly more opioids are prescribed for emergency department (ED) patients with acute pain compared to amounts consumed. Guidelines recommend prescribing a 3-day supply or 10-15 tablets of opioids for patients with acute pain Aim Statement: By January 2020, >70% of opioid prescriptions from our ED will be for <15 tablets of morphine 5 mg equivalents. Measures & Design: Emergency physicians were educated on best practice of prescribing opioids for discharged patients. An electronic prescription writer was built for discharged ED patients with a pop-up reminder for quantities >15 tablets (indicating a recommended quantity of 10-15 tablets) and a pop-up reminder for quantities >30 tablets (indicating a maximum quantity of 30 tablets and recommended quantity). A feature was built to auto-populate a prescription for morphine 5 mg po q4h prn x 10 tablets to facilitate adherence to guidelines. Outcome Measure % opioid prescriptions for <15 tablets of morphine 5 mg equivalents Process Measure Amount of opioids prescribed for discharged ED patients, measured as morphine 5 mg equivalents Number of opioid prescriptions for >30 tablets of morphine 5 mg equivalents Balancing Measure Number of patients that return to ED within 7 days and receive a repeat opioid prescription. Evaluation/Results: Prior to implementation of the electronic prescription writer a sample audit revealed that 50% of opioid prescriptions were written for <15 tablets of morphine 5 mg equivalents. For the first three quarters of 2019, 62%, 61% and 69% of opioid prescriptions were written for <15 tablets of morphine 5 mg equivalents. Only two prescriptions during the study period were for >30 tablets of morphine 5 mg equivalents. An average number of 7 patients per quarter were given a repeat opioid prescription during a return ED visit. Discussion/Impact: We were successful in influencing emergency physicians to prescribe fewer opioids to discharged patients. This has the potential to avoid converting ED patients with acute pain into long-term opioid users and to avoid the diversion of unused opioid tablets.

Background: Curbing unnecessary laboratory testing represents a significant opportunity for cost reduction in the Canadian health care system. A Choosing Wisely report cited a 31% decline in the number of tests ordered in a Canadian emergency department (ED) after implementation of recommendations. The international normalized ratio (INR) remains frequently ordered in emergency departments without an appropriate indication. Aim Statement: We aimed to reduce the number of INR tests completed in the St. Joseph's Healthcare Hamilton Emergency Department by 50% by April 30, 2019. Measures & Design: We conducted the study in an urban, academic ED employing the Epic electronic health record (EHR). We tailored interventions according to the Hierarchy of Effectiveness to address root causes revealed by analysis of our baseline ordering behaviour. Interventions included provider education around evidence-based ordering indications and removal of the INR from our “chest pain” bloodwork panel. Our outcome measure was the weekly number of INR tests completed per ED visit. Process measures included the proportion of INR tests ordered for inappropriate indications on monthly audits of 20 charts where an INR was completed. Balancing measures included average ED length of stay for patients receiving INR testing. Evaluation/Results: We collected outcome, process, and balancing measures through the EHR and analyzed this data using statistical process control charts. Over the nine-month study period, we decreased weekly INR tests from 248.4 to 115.0, a reduction of 56% which met criteria for special cause variation. This amounts to a cost savings of $43,008 per year. ED length of stay for patients receiving INR testing did not change significantly. Discussion/Impact: Our interventions were successful in realising our 50% target reduction in INR tests without an increase in ED length of stay from repeat venipuncture. This result is in keeping with similar efforts in other Canadian EDs. Our interventions could likely be spread to other settings where an INR is included as part of a “chest pain” panel. This may represent a substantial cost reduction opportunity on a national scale. Further work is needed in order to assess long term sustainability, which can be supported by employing high effectiveness mechanisms such as automation of optimal behaviour.

Introduction: Emergency department (ED) boarding is associated with worse outcomes for critically ill patients. There have been mixed findings in other patient populations. The primary objective of this study was to examine predictors of prolonged ED boarding among cancer patients receiving chemotherapy who required hospital admission from the ED. Secondary objectives were to examine the association between prolonged ED boarding and in-hospital mortality, 30-day mortality, and hospital length of stay (LOS). Methods: Using administrative databases from Ontario, we identified adult (≥ 18 years) cancer patients who received chemotherapy within 30 days prior to a hospital admission from the ED between 2013 to 2017. ED boarding time was calculated as the time from the decision to admit the patient to when the patient physically left the ED. Prolonged ED boarding was defined as ≥ 8 hours. Multivariable logistic regression was used to examine predictors of prolonged ED boarding and to determine if prolonged boarding was associated with mortality. Multivariable quantile regression was used to determine the association between prolonged boarding and hospital LOS. Results: 45,879 patients were included in the study. Median (interquartile range (IQR)) ED LOS of stay was 11.8 (7.0, 21.7) hours and median (IQR) ED boarding time was 4.2 (1.6, 14.2) hours. 17,053 (37.2%) patients had prolonged ED boarding. Severe ED crowding was the strongest predictor of prolonged ED boarding (odds ratio: 17.7, 95% CI: 15.0 to 20.9). Prolonged ED boarding was not associated with in-hospital mortality or 30-day mortality. Median hospital LOS was over 9 hours (p <0.0001) longer among patients with the longest ED boarding times. Conclusion: Severe ED crowding was associated with a significant increase in the odds of prolonged ED boarding. While our study demonstrated that prolonged boarding was not associated with increased mortality, further work is required to understand if ED boarding is associated with other adverse outcomes in this immunocompromised population.

Introduction: A physician handoff is the process through which physicians transfer the primary responsibility of a care unit. The emergency department (ED) is a fast-paced and crowded environment where the risk of information loss between shifts is significant. Yet, the impact of handoffs between emergency physicians on patient outcomes remains understudied. We performed a retrospective cohort study in the ED to determine if handed-off patients, when compared to non-handed-off patients, were at higher risk of negative outcomes. Methods: We included every adult patient first assessed by an emergency physician and subsequently admitted to hospital in one of the five sites of the CHU de Québec-Université Laval during fiscal year 2016-17. Data were extracted from the local hospital discharge database and the ED information system. Primary outcome was mortality. Secondary outcomes were incidence of ICU admission and surgery and hospital length of stay. We conducted multilevel multivariate regression analyses, accounting for patient and hospital clusters and adjusting for demographics, CTAS score, comorbidities, admitting department delay before evaluation by an emergency physician and by another specialty, emergency department crowding, initial ED orientation and handoff timing. We conducted sensitivity analyses excluding patients that had an ED length of stay > 24 hours or events that happened after 72 hours of hospitalization. Results: 21,136 ED visits and 17,150 unique individuals were included in the study. Median[Q1-Q3] age, Charlson index score, door-to-emergency-physician time and ED length of stay were 71[55-83] years old, 3[1-4], 48 [24,90] minutes, 20.8[9.9,32.7] hours, respectively. In multilevel multivariate analysis (OR handoff/no handoff [CI95%] or GMR[SE]), handoff status was not associated with mortality 0.89[0.77,1.02], surgery 0.95[0.85,1.07] or hospital length of stay (-0.02[0.03]). Non-handed-off patients had an increased risk of ICU admission (0.75[0.64,0.87]). ED occupancy rate was an independent predictor of mortality and ICU admission rate irrespectively of handoff status. Sensitivity and sub-group based analyses yielded no further information. Conclusion: Emergency physicians’ handoffs do not seem to increase the risk of severe in-hospital adverse events. ED occupancy rate is an independent predictor of mortality. Further studies are needed to explore the impact of ED handoffs on adverse events of low and moderate severity.

Introduction: ST-Elevation Myocardial Infarction (STEMI) represents irreversible necrosis of myocardial tissue. Prompt time-to-reperfusion in these patients is paramount in reducing morbidity and mortality. This concept, time-to-reperfusion, is the principle focus for improving STEMI care. Prioritizing diagnosis in patients with high-risk cardiac features through rapid electrocardiogram (ECG) is essential, with gold standard time-to-ECG benchmarked at 10-minutes. While substantial literature is established for pre-hospital ECG interventions, there is a paucity of intervention data for self-presenting patients. While evaluating these times within our department, we conducted a redesign of the triage process. These included nurses becoming the first contact and the addition of an extra triage nurse. These changes provided the opportunity to evaluate whether the redesign elements of the triage system meant to improve department flow could improve other patient-centered outcomes, namely time-to-ECG. Methods: The first fifty self-presenting patients designated as “cardiac chest pain” in the month preceding changes to the triage system were analyzed to create a baseline time-to-ECG value. Following the alteration to our triage system, three samples of the first 50 patient's time-to-ECG were collected at two, four and six months post-intervention and compared to pre-intervention via non-paired t-test. Data was further stratified into percentages of patients receiving an ECG within 10-minute intervals starting with 0-10 minutes. Proportions pre and post intervention were then compared using z-scores. Results: A baseline pre-intervention time-to-ECG value of 26.6 minutes was established. Average post-intervention time-to-ECG was significantly reduced at 15.6min with a mean difference of -11.0min ± 3.0 (95% CI -16.0 – (-5.0)). Interestingly, the proportion of ECGs performed under 20 minutes rose significantly from 58% to 81% (z=−3.2, p < 0.001) while the increase in proportion of ECGs performed under 10 minutes from 26% to 37% was not statistically significant (z=−1.4). Conclusion: The results of this analysis suggest that the addition of an extra triage nurse coupled with changing first point of ED contact from the business clerks to triage nurses significantly reduced mean time-to-ECG in self-presenting patients with chest pain deemed high risk for cardiac causes. Additionally, these changes significantly increased the proportion of ECGs performed within 20 minutes of ED arrival in these patients.

Introduction: Physicians who practice emergency medicine (EM) often perform procedural interventions, which can occasionally result in unintended patient harm. Our study's objective was to identify and describe the interventions and contributing factors associated with medico-legal (ML) cases involving emergency physicians performing procedural interventions. Methods: The Canadian Medical Protective Association (CMPA) is a not-for-profit, ML organization which represented over 99,000 physicians at the time of this study. We extracted five years (2014-2018) of CMPA data describing closed ML cases involving procedural interventions (e.g. suturing, reducing a dislocated joint) and excluding interventions related to pharmacotherapy (e.g. injection of local anesthetic), diagnosis (electrocardiograms) and physical assessments (e.g. ear exams), performed by physicians practicing EM. We then applied an internal contributing factor framework to identify themes. We analysed the data using descriptive statistics. Results: We identified 145 cases describing 145 patients who had 205 procedures performed in the course of their EM care. The three most common interventions were orthopedic injury management (47/145, 32.4%), wound management (43/145, 29.7%), and Advanced Cardiac Life Support (24/145, 16.6%). Out of 145 patients, 93.8% (136/145) experienced a patient safety event, and 55.9% (76/136) suffered an avoidable harmful incident. One quarter of patients suffered mild harm (34/76, 25.0%), 18.4% of patients died, 14.5% suffered severe harm, and 13.2% moderate harm. Peer experts were critical of 86/145 cases (59.3%) where the following provider contributing factors were found: a lack of situational awareness (20/68, 29.4%), and deficient physician clinical decision-making (54/68, 79.7%). Clinical decision-making issues included a lack of thoroughness of assessment (33/54, 61.1%), failure to perform tests or interventions (21/54, 38.9%), and a delay or failure to seek help from another physician (17/54, 31.2%). Peer experts were also critical of 48.8% of cases containing team factors (42/86) due to deficient medical record keeping (26/42, 61.9%), and communication breakdown with patients or other team members (25/42, 59.5%). Conclusion: Both provider and team factors contributed to ML cases involving EM physicians performing procedural interventions. Addressing these factors may improve patient safety and reduce ML risk for physicians.

Introduction: Out-of-hospital cardiac arrest (OHCA) constitutes a significant global health burden, with a survival rate of only 10-12%. Early intervention is vital but limited by ambulance response times, low rates of bystander assistance, and access to AEDs. Smartphone technologies have been developed that crowdsource willing volunteers to nearby OHCAs in order to initiate resuscitation prior to ambulance arrival. We performed a scoping review to map the available literature on these crowdsourcing technologies and compared their key operational features. Methods: A search strategy was developed for five online databases: Medline, Cochrane, Embase, and Web of Science, as well as Google Scholar. We searched for primary studies and grey literature describing mobile phone technologies that alerted users of nearby cardiac arrests in the community. Two reviewers independently screened all articles and extracted relevant study information. Subsequently, we performed a search of the Google and Apple app stores, a general internet search, and consulted experts to identify all available technologies that might not be described in literature. We contacted developers for information on technology use and specifications to create a detailed features table. Results: We included 72 articles examining bystander alerting technologies from 15 countries worldwide, owing to the increasing importance of this topic. We identified 25 unique technologies, of which 18 were described in the included literature. Technologies were either text message-based systems (n = 4) or mobile phone applications (n = 21). Most (23/25) used global positioning systems to direct bystanders to victims and nearby AEDs. Response radii for alerts varied widely from 200m to 10km. Some technologies had advanced features such as video-conferencing with ambulance dispatch and detailed alert settings. Not all systems required volunteers to have first aid training. There were 18 studies examining effects on bystander intervention, all of which showed significant improvements using the technologies. However, only six studies assessed impact on survival outcomes. Key barriers discussed included false positive alerts, legal liability, and potential psychological impact on volunteers. Conclusion: Our review provides a comprehensive overview of crowdsourcing technologies for bystander intervention in out-of-hospital cardiac arrest. Future work in this growing field should focus on survival outcomes and methods of addressing barriers to implementation.

Introduction: Delegation of controlled medical acts by physicians to paramedics is an important component of the prehospital care framework. Where directives indicate that physician input is needed before proceeding with certain interventions, online medical control (a “patch”) exists to facilitate communication between a paramedic and a Base Hospital Physician (BHP) to request an order to proceed with that intervention. The clinical and logistical setting will contribute to the decision to proceed with or withhold an intervention in the prehospital setting. The aim of this study was to examine the impact of various clinical and situational factors on the likelihood of a patch request being granted. Methods: Prehospital paramedic calls that included a mandatory patch point (excluding requests exclusively for termination of resuscitation and those records which were unavailable) were identified through review of all patch records from January 1, 2014 to December 31, 2017 for Paramedic Services in our region. Written Ambulance Call Reports (ACRs) and audio recordings of paramedic patches were obtained and reviewed. Results: 214 patch records were identified and screened for inclusion. 91 ACRs and audio patch records were included in the analysis. 51 of 91 (56%) patch requests were granted by the BHP. Of the 40 paramedic requests that were not granted, the most commonly cited reason was close proximity to hospital (22/40; 55%) followed by low likelihood of the intervention making a clinical impact in the prehospital setting (11/40; 27.5%). Requests for certain interventions were more likely to be granted than other requests. All requests to perform needle thoracostomy for possible tension pneumothorax, administer atropine for symptomatic bradycardia and treat hemodynamically unstable hyperkalemia were granted (2/2, 3/3 and 7/7, respectively), while requests for synchronized cardioversion (7/19; 37%) and transcutaneous pacing (2/6; 33%) were approved less than half of the time. Conclusion: This retrospective review suggests that requests to perform certain critical and potentially time sensitive interventions are more likely to be granted which calls into question the requirement for a mandatory patch point for these procedures. Furthermore, the interplay between proximity to hospital and the decision to proceed with an intervention potentially informs future modifications to directives to facilitate timely, safe and efficient care.
