MP26: An emergency department team-based quality improvement initiative reduces narcotic and benzodiazepine ‘to-go’ medication administration
Authors: Harris D. , Karogiannis D. , Balfour N. , Gerry M. , Mushta J. , Cabral J.
Published: May 2018

Introduction: The administration of “to-go” medications in the Kelowna General Hospital Emergency Department was identified as an issue. Frequently, multiple administrations of “to-go” medication pre-packs were administered to individual patients on a frequent basis. In addition, the variability in “to-go” medication was substantial between providers. Recognizing the patient issues (addiction, dependency and diversion) and system issues (costs, risk) a team-based quality improvement initiative was instituted, utilizing a variety of quality improvement techniques. The aim was to reduce the number of “to-go” medications by half, within a year. Methods: The project began January 2015, and is ongoing. Multiple stakeholders were engaged within the emergency department; these included leaders of the physician, nursing and pharmacy teams, including an executive sponsor. Using change theory, and traditional Plan-Do-Study-Act (PDSA) cycles, an iterative methodology was proposed. The outcome measure proposed was number of “to-go” medications administered; secondary measures included number of opioid “to-go” and benzodiazepine “to-go“prescriptions. Balancing measures were the number of narcotic prescriptions written. Physician prescribing practice and nursing practice were reviewed at meetings and huddles. Individualized reports were provided to physicians for self-review. Data was collated at baseline then reviewed quarterly at meetings and huddles. Run charts were utilized along with raw data and individualized reports. Results: At baseline (January 2015), the number of “to-go” medications was 708. Over the next year, this value reduced to 459, showing a 35% reduction in “to-go”. Two years later (June 2017), this had reduced to 142, resulting in an overall reduction of 80% “to-go” medications. Secondary measures are currently under analysis. Further, no increase in prescribing of narcotics was seen during this time period. Conclusion: The administration of “to-go” medications from the emergency department has significant individual and societal impact. Frequently, these medications are diverted; meaning, sold for profit on the black market. Further, opioid prescribing is under increased scrutiny as the linkage between opioid prescriptions and addiction / dependency becomes more evident. This quality improvement initiative was successful for a number of reasons. First, we had strong engagement from the full emergency department clinical teams. The issue was first identified collaboratively, and teamwork and participation was strong from the outset. Second, we used individual and aggregate data to provide feedback on a regular basis. Third, we had strong support from our executive sponsor(s) who were able to support the efforts and champion and present the results locally, and now, throughout the Health Region.

Introduction: In many rural and remote communities in BC, family physicians who are providing excellent primary and emergency care would like to access useful, timely, and collegial support to ensure the highest quality of health services for their patients. We undertook a real-time virtual support project in Robson Valley, located in northern BC, to evaluate the use of digital technologies such as videoconferencing for on demand consultation between family physicians at rural sites and emergency physicians at a regional site. Telehealth consults also occurred between rural sites with nurses at community emergency rooms consulting with local on-call physicians. Our aim was to use telehealth to facilitate timely access to high quality, comprehensive, coordinated team-based care. An evaluation framework, based on the Triple Aim sought to: 1) Identify telehealth use cases and assess impact on patient outcomes, patient and health professional experience, and cost of health care delivery; and 2) Assess the role of relationships among care team members in progressing from uptake to normalization of telehealth into routine usage. Methods: Using a participatory approach, all members of the pilot project were involved in shaping the pilot including the co-development of the evaluation itself. Evaluation was used iteratively throughout implementation for ongoing quality improvement via regular team meetings, sharing and reflecting on findings, and adjusting processes as required. Mixed methods were used including: interviews with family physicians, nurses, and patients at rural sites, and emergency physicians at regional site; review of records such as technology use statistics; and stakeholder focus groups. Results: From November 2016 to July 2017, 26 cases of telehealth use were captured and evaluated. Findings indicate that telehealth has positively impacted care team, patients, and health system. Benefits for care team at the rural sites included confidence in diagnoses through timely access to advice and support, while emergency physicians at the regional site gained deeper understanding of the practice settings of rural colleagues. Nevertheless, telehealth has complicated the emergency department work flow and increased physician workload. Findings demonstrated efficiencies for the health system, including reducing the need for patient transfer. Patients expressed confidence in the physicians and telehealth system; by receiving care closer to home, they experienced personal cost savings. Implementation saw a move away from scheduled telehealth visits to real use of technology for timely access. Conclusion: Evidence of the benefits of telehealth in emergency settings is needed to support stakeholder engagement to address issues of workflow and capacity. This pilot has early indications of significant local impact and will inform the expansion of emergency telehealth in all emergency settings in BC.
MP36: Can one emergency physician improve department flow? A proof-of-concept trial of a physician float role

Published: May 2018

Introduction: Emergency departments (EDs) are overcrowded and patient acuity and volumes are ever-increasing. While changes to the flow of ED patient input and output are outside the control of frontline ED teams, the efficiency of ED throughput can be optimized. One widely studied intervention is the implementation of a physician liaison role to assist in managing overall ED flow. The Physician Float (PF) acts as a triage liaison, second physician for resuscitations, ED procedural sedation physician, and fields ED referral calls. This is a first-iteration proof-of-concept trial to plan, implement and evaluate if the PF role could decrease ED length of stay (LOS) by a goal of 30 minutes, over a four-week period, without adverse changes to left without being seen (LWBS) and bounce-back rates. Methods: The PF role was implemented as a scheduled emergency physician shift in the fall of 2017. Ongoing iterations of this role implementation are being reviewed for re-implementation. The primary outcome measure was ED LOS; secondary outcomes included time-to-physician initial assessment (PIA), EMS offload rates, and LWBS and 72-hour bounce-back rates. Qualitative data including patient concerns and physician feedback were also collected. Data were collected after the trial from a centralized, de-identified ED information system database with time-stamp quantifiers and compared to the following four-week time period where the shift is a regular ED physician shift at the same time. The ED physician and nursing team planned and implemented the PF role, then results were evaluated and shared with the wider ED staff in departmental grand rounds and quality council presentation formats, and recommendations were gathered from to adjust and strengthen future iterations of PF role implementation. Results: Descriptive statistics and Mann-Whitney and Median tests were calculated. On average there were 185 daily ED visits in the trial and comparison periods. Median ED LOS decreased by 12 minutes in the PF trial period (p<0.05). Furthermore, there was a 12 minute decreased ED LOS for all discharged patients (p<0.05). PIA time decreased by 13 minutes for patients that were admitted. The average percentage of EMS offloads within 60 min improved from 75% to 80.7% for admitted patients. LWBS and 72-hour bounce-back rates were unchanged. No additional patient concerns arose related to or during the trial. Physician feedback on the PF role was mainly positive. Conclusion: The defined role of a PF in an ED can decrease ED LOS, albeit not achieving the desired 30-minute reduction on the first iteration, this trial supported proof-of-concept for implementation of a PF role in a tertiary care centre ED. Further iterations are needed to evaluate the scalability and sustainability of this role.

Published: May 2018

Introduction:
As utilization of CT imaging has risen dramatically, evidence-based decision rules and clinical decision support (CDS) tools have been developed to avoid unnecessary CT use in low risk patients. However, their ability to change physician practice has been limited to date, with a number of barriers cited. The purpose of this study was to identify the barriers and facilitators to CDS adoption following a local CDS implementation. Methods: All emergency physicians at 4 urban EDs and 1 urgent care center were randomized to voluntary evidence-based CT imaging CDS for patients with either mild traumatic brain injury (MTBI) or suspected pulmonary embolism (PE). CDS was integrated into the computerized physician order entry (CPOE) software and triggered whenever a CT scan for an eligible patient was ordered. Physicians in both the MTBI and PE arms were ranked according to their CDS use, and a stratified sampling strategy was used to randomly select 5 physicians from each of the low, medium and high CDS use tertiles in each study arm. Each physician was invited to participate in a 30-minute semi-structured interview to assess the barriers and facilitators to CDS use. Physician responses were reported using a thematic analysis. Results: A total of 202 emergency physicians were randomized to receive CDS for either MTBI or PE, triggering CDS 4561 times, and interacting with the CDS software 1936 times (42.4%). Variation in CDS use ranged from 0% to 88.9% of eligible encounters by physician. Fourteen physicians have participated in interviews to date, and data collection is ongoing. Physicians reported that CDS use was facilitated by their confidence in the evidence supporting the CDS algorithms and that it provided documentation to reduce medico-legal risk. CDS use was not impeded by concerns over missed diagnoses or patient expectations. Reported barriers to CDS use included suboptimal integration into the CPOE such as the inability to auto-populate test results, it disrupted the ordering process and was time consuming. A common concern was that CDS was implemented too late in workflow as most decision making takes place at the bedside. Physicians did not view CDS as infringing on physician autonomy, however they advised that CDS should be a passive educational option and should not automatically trigger for all physicians and eligible encounters. Conclusion: Physicians were generally supportive of CDS integration into practice, and were confident that CDS is an evidence-based way to reduce unnecessary CT studies. However, concerns were raised about the optimal integration of CDS into CPOE and workflow. Physicians also stated a preference to a passive educational approach to CDS rather than an automatic triggering mechanism requiring clinical documentation.
P003: Which factors predict resuscitation outcomes in patients arriving to the emergency department in cardiac arrest? A SHoC series study

Published: May 2018

Introduction: The decision as to whether to end resuscitation for pre-hospital cardiac arrest (CA) patients in the field or in the emergency department (ED) is commonly made based upon standard criteria. We studied the reliability of several easily determined criteria as predictors of resuscitation outcomes in a population of adults in CA transported to the ED. Methods: A retrospective database and chart analysis was completed for patients arriving to a tertiary ED in cardiac arrest, between 2010 and 2014. Patients were excluded if aged under 19. Multiple data were abstracted from charts using a standardized form. Regression analysis was used to compare criteria that predicted return of spontaneous circulation (ROSC) and survival to hospital admission (SHA). Results: 264 patients met the study inclusion criteria. Logistic regression was used to identify predictors of ROSC and SHA. The criteria that emerged as significant predictors for ROSC included; longer ED resuscitation time (Odds ratio 1.11 (1.06- 1.18)), witnessed arrest (Odds ratio 9.43 (2.58- 53.0)) and having an initial cardiac rhythm of Pulseless Electrical Activity (Odds Ratio 3.23 (1.07-9.811)) over Asystole. Receiving point of care ultrasound (PoCUS; Odds ratio 0.22 (0.07-0.69)); and having an initial cardiac rhythm of Pulseless Electrical Activity (Odds Ratio 4.10 (1.43-11.88)) were the significant predictors for SHA. Longer times for ED resuscitation was close to reaching significance for predicting SHA Conclusion: Our results suggest that both fixed and adaptable factors, including increasing resuscitation time, and PoCUS use in the ED were important independent predictors of successful resuscitation. Several commonly used criteria were unreliable predictors.
P017: When the rules hit the road: how emergency physicians make decisions in the era of the Clinical Decision Rules
Authors: Chan T. M. , Mercuri M. , de Wit K.
Published: May 2018

Introduction: The diagnostic process is wrought with potential sources of error. Psychologists seek to coach physicians to refine their cognition. Researchers try to create cognitive scaffolds to guide decision-making. Physicians however, are caught in middle between their own daily cognitive processes and these external theories that might influence their behaviour. Few attempts have been made to understand how experienced clinicians integrate guidelines or clinical decision rules (CDRs) into their decision-making. We sought to explore experienced clinicians decision-making via a simulated exercise, to develop a model of how physicians integrate CDRs into their diagnostic thinking. Methods: From July 2015-March 2016, 16 practicing emergency physicians (EPs) were interviewed via a think aloud protocol study. Six cases were constructed and video recorded as prompts to spur the clinicians to think aloud and describe their approach to the cases. Cases were designed to be slightly suggestive for pulmonary embolism or deep vein thrombosis, since these conditions are associated with CDRs. Using a constructivist grounded theory analysis, three investigators independently reviewed the transcripts from the interviews, meeting regularly to discuss emergent themes and subthemes until sufficiency was reached. Disagreements about themes were resolved by discussion and consensus. Results: Our analysis suggests that physicians engage in an iterative process when they are faced with undifferentiated chest pain and leg pain cases. After generating an original differential diagnosis, EPs engage in an iterative diagnostic process. They flip between hypothesis-driven data collection (e.g. history, physical exam, tests) and analysis of this data, and use this process to weigh probabilities of various diagnoses. EPs only apply CDRs once they are sufficiently suspicious of a diagnosis requiring guidance from a CDR and when they experience diagnostic uncertainty or wish to bolster their decision with evidence. Conclusion: EP cognition around diagnosis is a dynamic and iterative process, and may only peripherally integrate relevant CDRs if a threshold level of suspicion is met. Our findings may be useful for improving knowledge translation of CDRs and prevent diagnostic error.
P019: The path of least resistance: how computerized provider order entry can lead to (and reduce) wasteful practices
Authors: Choi J.
Published: May 2018

Introduction: Background Computerized provider order entry (CPOE) is rapidly becoming the mainstay in clinical care and has the potential to improve provider efficiency and accuracy. However, this hinges on careful planning and implementation. Poorly planned CPOE order sets can lead to undetected errors and waste. In our emergency department (ED), lactate dehydrogenase (LDH) was bundled into various blood work panels, but had little clinical value. Aim Statement This quality improvement initiative aimed to reduce unnecessary LDH testing in the ED. Methods: Methods A group of ED physicians reviewed CPOE blood work panels and uncoupled LDH in conditions where it was deemed not to provide any clinically useful information. We measured the daily number of LDH tests performed before and after its removal. We tracked the frequency of other serum tests as controls. We also analyzed the number of add-on LDH (i.e. to add LDH to samples already sent to the lab) as a balancing measure, since this can disrupt work flow and delay care. Results: Results Through this intervention, we reduced the number of LDH tests performed by 69%, from an average of 75.1 tests per day to 23.2 (p<0.0005). The baseline controls did not differ after the intervention (e.g. a complete blood count was performed 197.7 and 196.1 times per day pre- and post-intervention, respectively [p=0.7663]). There was less than 1 add-on LDH per day on average. This translates to a cost savings of $33,340.65 at our institution. Conclusion: Conclusions CPOE care templates can be powerful in shaping behaviours and reducing variability. However, close oversight of these panels is necessary to prevent errors and waste.
P048: Interprofessional airway microskill checklists facilitate the deliberate practice of surgical cricothyrotomy with 3-D printed surgical airway trainers
Authors: French J.P. , David K. , Benjamin S. , Fraser J. , Mekwan J. , Atkinson P.
Published: May 2018

Introduction: Deliberate practice (DP) is the evolution of practice using continually challenging and focused practice on a particular task. DP involves immediate feedback, time for problem-solving and evaluation, and opportunities for repeated performance. Microskills training breaks down larger tasks into multiple smaller subtasks and then adds opportunities for feedback and adjustment for each subtask. Microskills training is routinely used to achieve excellence in competitive sports, martial arts, military operations, and music. Surgical cricothyrotomy is a rarely performed safety critical task. Methods: Two doctors and three nurses developed stepwise team microskills checklists from case review, simulations and published evidence. The checklist was tested, evaluated and developed during four days of simulation faculty team training. The final 30 item checklist was used to facilitate skills training for doctors, nurses, respiratory therapists and ACPs in one level 2, and two level 3 trauma centers from April 2017 to October 2017. Commonly available airway trainers were retrofitted with the 3-D printed larynx. The microskills checklist was used in four phases: 1. Group discussion of each microskill step; 2. Groups of three team members; operator, assistant and microskill facilitator (using the checklist) to enable the deliberate analysis of the teams current performance. Each subtask is performed with immediate peer and where necessary faculty feedback - changes are recorded; 3. Total task run through without interruption - changes are recorded; 4. Repetition and feedback using different team members, manikins, including time pressure. User satisfaction surveys were collected after the skills training session Results: Teams were composed of Registered Nurses (8), Physicians (9), and Respiratory Therapists (2). All of the teams experienced a change in practice. The median number of microskills changed for MDs 12/21, RNs 6/12. The commonest changes in practice were equipment preparation (all teams). All professions agreed strongly that the approach produces a positive change in practice (median score 5/5). Conclusion: Microskills checklists facilitate cricothyrotomy skill development in interprofessional teams in this provisional analysis.

Introduction: Increase in functional decline of older adults after discharge from the emergency department (ED) has been reported; however, evaluations of interventions to mitigate this problem are infrequent. Data collected in the ED on older adults may document functional status, yet their utility for research is unknown. This study aimed to assess the usability of data collected by ED Transition Coordinators (EDTC) during routine assessments for functional decline research. Methods: EDTCs assess all patients 75 years old presenting to the ED and complete a standardized Transitional Assessment Referral (TAR) form that documents patients independence and daily functioning. To measure the utility of these forms for research purposes, trained research staff evaluated the TARs completed in April 2017 by TCs in the University of Alberta Hospital ED by extracting data from the TARs into a purpose-built REDCap database. Researchers selected and assessed for completeness and clarity the following variables unique to the TARs: facility vs. non-facility living, goals of care and personal directive, fall history, falls in the past 90 days, independence in 14 activities of daily living (ADLs)/instrumental activities of daily living (IADLS), community services in place, and homecare referrals for discharged patients. The proportion of TARs with data for each variable and the proportion of forms with unambiguous responses in each section are reported. Results: Overall, 500 forms were analysed; patients were 41% male with a mean age of 82 (SD=11.2). Homecare referrals, facility vs. non-facility living, and independence with 14 ADLs/IADLs were the most frequently documented variables (81%, 78%, and 79%, respectively); however for ADLs/IADLs, 59% of the 79% had one or more missing components. While fall history was reported in 301 forms (60%), only 107/301 (36%) reported the number of falls in the last 90 days. The referral to homecare variable was complete in 217/268 (81%) forms; however, 99% of files were missing data about goals of care, personal directives, and receipt of community services. Conclusion: Although some information on elderly patients is consistently reported, many of the social service/human factors associated with functional decline are not recorded. While data on the TARs may be useful for studying functional decline in the ED, exploring the barriers to form completion may improve adherence thereby increasing their research utility.

Published: May 2018

Introduction: Anaphylaxis is a life-threatening condition that paramedics are equipped to treat effectively in the field. Current literature suggests improvements in paramedic recognition and treatment of anaphylaxis could be made. The aim of this study was to compare the proportion of cases of anaphylaxis appropriately treated with epinephrine by paramedics before and after a targeted educational intervention. Methods: This was a retrospective medical records review of patients with anaphylaxis managed by primary or advanced care paramedics in five Emergency Medical Service areas in Ontario, before and after an educational module was introduced. This module included education on anaphylaxis diagnosis, recognition, treatment priorities, and feedback on the recognition and management from the before period. All paramedic call records (PCRs) coded as local allergic reaction or anaphylaxis during 12-month periods before and after the intervention were reviewed by trained data abstractors to determine if patients met an international definition of anaphylaxis. The details of interventions performed by the paramedics were used to determine primary and secondary outcomes. Results: Of the 600 PCRs reviewed, 99/120 PCRs in the before and 300/480 in the after period were included. Of the charts included, 63/99 (63.6%) in the before and 136/300 (45.3%) in the after period met criteria for anaphylaxis (p=0.002). Of the cases meeting anaphylaxis criteria, 41/63 (65.1%) in the before and 88/136 (64.7%) in the after period were correctly identified as anaphylaxis (p=0.96). Epinephrine was administered in 37/63 (58.7%) of anaphylaxis cases in the before period and 76/136 (55.9%) in the after period (p=0.70). Anaphylactic patients with only two-system involvement received epinephrine in 20/40 (50.0%) cases in the before period and 45/93 (48.4%) in the after period (p=0.86). Conclusion: There are gaps in paramedic recognition and management of anaphylaxis, particularly in cases of two-system involvement. These gaps persisted after the implementation of an educational intervention. Other quality interventions and periodic refreshers may be necessary to improve prehospital treatment of anaphylaxis. Limitations include an increase in overall cases and decrease in rate of true anaphylaxis in the after period, which may relate to better case identification after electronic PCR implementation and changes in paramedic recognition.
P064: Characteristics of physical space that optimize clinical learning in the emergency department: implications for design
Authors: Hasan M. A. , Snell L. , Nugus P.
Published: May 2018

Introduction: Over the last few decades, health care facility design has been studied to look at its effect on many patient-centred outcomes. However, limited data exists on the impact that specific physical features of a clinical space may have on learning and the educational experience. The aim of this study is to develop a set of characteristics which clinicians, clinical teachers and residents believe should be present in a clinical space to maximize trainees learning, using an emergency department (ED) as a context. Methods: A qualitative methodology used semi- structured interviews with a purposive sample of twelve attending physicians and residents who work in EDs of varying age and design at several sites of a quaternary university hospital. We explored their perceptions of the physical features in the clinical and learning environment that supported or impeded teaching and learning. The interviews were transcribed and thematically analyzed. Results: Preliminary results show that many physical characteristics of the clinical space are perceived to have an impact on trainees learning experience. A design with separation between clinician-learner dyads and the patients, with a visual access; shared clinical space among different health care professionals within a reasonable distance; availability of enough clinical space for specific emergency presentations; features such as adequate size, appropriate light, and control of sound were all perceived to enhance and augment clinical learning. Not surprisingly, non-design factors such as the presence of a functioning team and the availability of adequate equipment and technology was considered as important as the characteristics of physical space to optimize learning. Conclusion: This study demonstrates the importance and the impact of physical space design on trainees learning in a dynamic clinical environment. It provides teachers and policy-makers with a basis for developing criteria of the physical characteristics of a healthcare facility to maximize learning.
P093: Performing the balancing act: emergency medicine physicians’ multifaceted roles and their influence on trainee assessment
Authors: Chan T. M. , Li S. , Acai A. , Sherbino J.
Published: May 2018

Introduction: Competency-based workplace assessments are important in clinical training. However, feedback and assessment are still often perceived as unsatisfactory, particularly in busy settings such as emergency departments. Currently, little is known about how attending staff physicians sense of self may interface with the processes they use to assess and give feedback to trainees. We aimed to understand how attendings perceive their roles when tasked with conducting assessments and providing feedback to trainees. Methods: We conducted semi-structured, individual interviews with attendings (n=16) who used McMAP (McMaster Modular Assessment Program), a workplace-based assessment system at McMaster Universitys Royal College Emergency Medicine program. Attendings were recruited using snowball sampling. Data were interpreted using thematic analysis, sensitized to the dramaturgical lens and rater cognition frameworks. Results: Attendings identified themselves using three distinct but intimately connected roles when assessing trainee performance: the doctor that ensures the safety and well-being of patients; the coach (educator) that empowers, guides, and supports the next generation of medical doctors; and the assessor that formally assesses a trainees progression through the residency program. These roles are influenced by clinical training and experience, teaching experience and context. Conclusion: The ways in which attendings assess and provide feedback to trainees involve a complex and dynamic process that is influenced by their perceived roles as a doctor, coach, and assessor. Understanding the way attendings view and juggle their roles may provide insight into potentially new approaches to assessment and feedback. Results and implications will be discussed.

Published: May 2018

Introduction: Tertiary care emergency departments (EDs) in large urban environments may have a low volume of high acuity pediatric presentations due to their proximity to dedicated childrens hospitals or large community centres. This may lead to discomfort among emergency physicians (EPs) and registered nurses (RNs) in managing these patients and a waning of knowledge and skills for this unique population. Among the EP group at our institution, 68% indicated they managed pediatric patients in less than 25% of their shifts, 68% also indicated they were uncomfortable managing an undifferentiated critically unwell neonate and only 32% indicated they would be comfortable teaching pediatric topics to emergency medicine residents. At our institution, our innovation was to create a useful curriculum for certified EPs and RNs to improve the interdisciplinary teams comfort level, knowledge and skill set when managing pediatric emergencies. Methods: A needs assessment was undertaken of the EPs and RNs working in our centre. This information was used to develop intended learning outcomes in a collaborative manner with the clinical nursing educator and physician curriculum leads. The team further collaborated with the local simulation centre and a pediatric emergency physician from the local childrens hospital. Results: A one-year, three-module curriculum was developed to cover the areas felt to be highest yield by the EP group: febrile illness, respiratory disease and critically ill neonates and infants. Each module contains three components: an in person interactive lecture delivered by an EP who routinely manages pediatric patients, either at a childrens hospital or large community centre; an online component with e-mail blasts of high yield pediatric content; and, culminating in an interdisciplinary interdepartmental simulation held in situ. This latter is particularly important so that all members of the interdisciplinary team can practice finding and using equipment based on its actual location within the ED. Each component of each module is then evaluated by the participants to ensure improvement for subsequent delivery. Conclusion: Well delivered continuing professional development (CPD) will become increasingly important as competence by design becomes the model for maintenance of certification. Maintaining skills for pediatric patients is an important component of CPD for physicians working in general emergency departments that see a low volume of high acuity pediatric presentations. Our curriculum seeks to address this identified need in an innovative manner using a modular and interdisciplinary approach with a diversity of teaching methods to appeal to the learning styles among our health care team.
P124: A new in-skates balance error scoring system for the sideline assessment of concussion in hockey players
Authors: Robert A. , Moroz M. , Var D. , Correa J. , Delaney S.
Published: May 2018

Introduction: During a hockey game, athletes who are suspected of having sustained a concussion are removed from the game and evaluated. The modified balance error scoring system (MBESS) assessment, an essential part of the concussion evaluation, is performed in the dressing room, barefoot on a hard surface after equipment removal. While, players that pass the concussion assessment may re-dress and return to play, the equipment removal and re-dressing delays their return into the game. The objective of our study was to develop and evaluate a new in-skates balance error scoring system (SBESS) to reduce the delay in returning to the game. Methods: A prospective randomized single blinded study was conducted with 80 healthy university hockey players split into two groups. An at-rest group performed the SBESS assessment at rest on two separate occasions. A post-exercise group performed the test once at rest and once after exercise. The SBESS consisted of performing 4 different stances for 20 seconds each without equipment removal. The assessments were video recorded, and 3 independent reviewers scored the videos. For both the at-rest and post-exercise groups, the primary outcome measured was the number of balance errors. The secondary outcome was the number of falls. Statistics: For the primary outcome, both inter-rater and intra-rater reliability were calculated. The concordance between the SBESS and the currently used baseline pre-season balance score (MBESS) was also assessed. Results: The number of cumulative balance errors for all four stances varied between 4 and 7 for both groups without any significant exercise effect. No athletes fell. For inter-rater reliability, the intra-class correlation (ICC) was above 0.86, ranging from 0.86-0.92 for most stances except for the easiest stance, for which it was 0.66. For intra-rater reliability, the ICC ranged from 0.88 to 1 for all stances and raters. There was a lack of concordance between the SBESS and MBESS. Conclusion: The SBESS is a reliable balance test that can be safely performed in healthy athletes wearing their full equipment. The next step will be to evaluate the use of this test on concussed hockey athletes
P138: Using electronic health record data to assess emergency medicine trainees independent and interdependent performance: a qualitative perspective on measuring what matters

Published: May 2018

Introduction: Competency-based medical education (CBME) affirms that trainees will receive timely assessments and effective feedback about their clinical performance, which has inevitably raised concerns about assessment burden. Therefore, we need ways of generating assessments that do not rely exclusively on faculty-produced reports. The main object of this research is to investigate how data already collected in the electronic health record (EHR) might be meaningfully and appropriately used for assessing emergency medicine (EM) trainees independent and interdependent clinical performance. This study represents the first step in exploring what EHR data might be utilized to monitor and assess trainees clinical performance Methods: Following constructivist grounded theory, individual semi-structured interviews were conducted with 10 EM faculty and 11 EM trainees, across all postgraduate years, to identify EHR performance indicators that represent EM trainees independent and interdependent clinical actions and decisions. Participants were presented with a list of performance indicators and asked to comment on how valuable each would be in assessing trainee performance. Data analysis employed constant comparative inductive methods and occured throughout data collection. Results: Participants created, refined, and eliminated performance indicators. Our main result is a catalogue of clinical performance indicators, described by our participants, as reflecting independent and/or interdependent EM trainee performance that are believed to be captured within the EHR. Such independent indicators include: number of patients seen (according to CTAS levels), turnaround time between when a patient is signed up for and first orders are made, number of narcotics prescribed. Meanwhile, interdependent indicators include, but are not limited to, length of stay, bounce-back rates, ordering practices, and time to fluids. Conclusion: Our findings document a process for developing EM trainee report cards that incorporate the perspectives of clinical faculty and trainees. Our work has important implications for distinguishing between independent and interdependent clinical performance indicators.

Introduction: Inspired by the Choosing Wisely® campaign, St. Michaels Hospital (SMH) launched an initiative to reduce unnecessary tests, treatments and procedures that may cause patient harm. Stakeholder engagement identified inappropriate ordering of urine culture & sensitivities (C&S) in the emergency department (ED) as a focus area. Inappropriate urine C&S increase workload, healthcare costs and detection of asymptomatic bacteriuria which can lead to unnecessary antibiotics. The project’s purposes were to describe the scope of inappropriately ordered urine C&S in the SMH ED and to conduct a root-cause analysis to inform future quality improvement interventions. Methods: Criteria for determining appropriateness was developed a priori using evidence-based guidelines from the University Health Network together with additional literature review. A retrospective chart review was performed on all urine C&S ordered in the ED from Jun 1 Aug 30, 2016. Each chart was reviewed for order appropriateness, demographic information and ordering provider. All inappropriate urine C&S were reviewed to identify root causes which were then grouped into common themes. A pareto chart was constructed to analyze the frequency of causes. Results: Of 425 urine C&S ordered, 75 (17.7%) were inappropriate. The top 3 reasons were: inappropriate urosepsis work-ups (53%), order processing errors (17%) and inappropriate work-ups for weakness (16%). Inappropriate urosepsis work-ups were defined as urine C&S that were ordered empirically despite there being a clear focus for infection elsewhere (i.e. cough, cellulitis) and in the absence of urinary symptoms. Order processing errors were defined as urine C&S which were sent despite there being no documented order. Inappropriate testing was more likely to occur overnight, in females and when a urine routine and microscopy was not ordered prior to C&S. 29% of patients with inappropriate C&S received antibiotics. Conclusion: 17.7% of urine C&S ordered in the SMH ED during the 3-month study period were inappropriate. The top cause was septic patients who were empirically tested despite having another source for infection identified from the outset. A possible reason for this is the recent ED emphasis on early recognition of sepsis which may encourage early use of antibiotics and empiric urine C&S. One question to resolve is whether a 17.7% overutilization rate is sufficient to make it a target for change. Interventions designed to reduce inappropriate urine C&S may inadvertently increase the number of missed cultures in patients admitted with sepsis not yet diagnosed. Next steps involve discussions between the ED, Internal Medicine, Infectious Disease and Microbiology, and patient partners to identify patient-centered change ideas and sustainable strategies. This may involve establishing guidelines for ordering urine C&S and incorporating lab services to provide oversight into urine C&S processing.

Introduction: Intubation is one of the highest-risk procedures performed in the ED. Few Canadian centres monitor intubation frequency, indications, methods used, success, and/or complication rates. An airway registry that tracks patient outcomes and variation in practice would be a valuable quality improvement (QI) tool. We describe the development of the BC-Airway Registry for Emergencies (BCARE) network, an emergency intubation database at two tertiary-care and one community hospital. Methods: Respiratory Therapists (RTs) are present at every intubation outside of the OR and complete a standardized post-intubation form. The airway forms were developed collaboratively with input from RTs, emergency physicians, intensivists, and anesthetists. Completed forms are collected from participating sites and data is entered into a secure online database where patient outcomes are analyzed in real-time. Results: We collected data from 737 unique intubations over 19 months with ongoing enrolment at the time of abstract submission. Mean age was 59.4 (Range 17-95, SD 17.6), Male 66.2%, intubation locations were ED (396, 53.7%), ICU (221, 30.0%), Ward (120, 16.3%). The most common indications for ED intubation were ICH/stroke (14.6%), seizure (10.9%), and sepsis (9.5%). Intubations are done by attending physicians more frequently in the ED (48.0%) compared to in the ICU (11.8%), and ward (8.6%). ED intubations were more commonly performed using video laryngoscopy (57.7%) with a smaller proportion using direct laryngoscopy (39.0%). First-pass success was 81.8% in the ED, 79.2% in the ICU, and 77.5% on the wards. Of ED intubations, 56 (14.1%) had complications and 73 (18.4%) were considered to be a difficult airway. Conclusion: The BCARE network tracks intubation performance across hospitals and is a valuable QI tool. BCARE can be used to ensure that all centres are meeting a benchmark success rate, for assessing the impact of practice changes such as pre-intubation checklists, and for implementing systematic methods to identify patients who previously had a “difficult airway.”
PL03: Prophylactic administration of diphenhydramine to reduce neuroleptic side-effects in the acute care setting: a systematic review and meta-analysis

Introduction: Neuroleptics are commonly used drugs to treat different conditions (e.g. psychosis, migraines) in the acute care setting and the emergency department. Their side effects can be disabling or, worse, fatal. The use of diphenhydramine to prevent those side-effects is widespread, but remains controversial. We performed a systematic review to determine if prophylactic administration of diphenhydramine (PAD) reduces the incidence of neuroleptic side-effects. Methods: Data sources: Medline, Embase, Cochrane Library, PsycInfo and Web of Science were searched. References from reviews that were identified in the search and from included studied were also reviewed for inclusion. Study selection: Randomized controlled trials evaluating any neuroleptic with PAD versus the same neuroleptic alone or with any inactive agent. Primary outcome was incidence of any extra-pyramidal side-effect. Secondary outcomes were akathisia, usage of rescue medication, subjective restlessness, neuroleptic malignant syndrome, sedation and sedation intensity. Data extraction: Independent reviewers scanned identified citations, extracted data and assessed for risk of bias. Data analysis: Meta-analysis was performed using random effect models. Heterogeneity and quality of evidence were assessed using, respectively, I2 and the GRADE approach. Results: Results: Of 1566 identified citations, nine studies (n=1436) met all eligibility criteria. Four studies were specifically designed to assess for neuroleptic side-effects. Four studies were at high risk of bias. In primary analysis, PAD had no effect on the incidence of extra-pyramidal symptoms (7 studies, n=1393 patients, RR 0.70 [0.40-1.22]), akathisia (5 studies, n=1094 patients, RR 0.81 [0.36-1.82]) and sedation (5 studies; n=1079, RR 1,48 [0.90-2.42]). Higher dosage of diphenhydramine was not associated with a greater reduction of extra-pyramidal side-effects. In a sensitivity analysis excluding an outlier study (n=120, RR 6.63 [1.55-28,35]), PAD was associated with a significant decrease in extra-pyramidal side-effects (6 studies, n=1273, RR 0.56 [0,38-0.82]), but not with any of the secondary outcome measures. Conclusion: Conclusion: When excluding an outlier study, PAD was associated with a significant reduction of extra-pyramidal side-effects. However, PAD did not significantly influence the incidence of akathisia. Overall quality of evidence is low. Further studies are warranted. PAD represents an interesting treatment option against neuroleptic side-effects, but its widespread usage whitout strong evidence to support it raises concerns.
