A Global Survey of Emergency Care Clinical Networks: Discussion and Implications for Canadian Learning Health Systems.

Clinical networks (CNs) can promote innovation and collaboration across providers and stakeholders. However, little is known about the structure and operations of CNs, particularly in emergency care. As Canada advances learning health systems (LHSs), foundational research is essential to enable future comparisons across CNs to identify those that contribute to positive system change. Drawing from the results of our international survey, we provide a description of 32 emergency care CNs worldwide, including their structure, operations and sustainability. Future research should consider the context of such networks, how they may contribute to an LHS and how they impact patient outcomes.

Concordance between 8-1-1 HealthLink BC Emergency iDoctor-in-assistance (HEiDi) virtual physician advice and subsequent health service utilization for callers to a nurse-managed provincial health information telephone service.

BACKGROUND: British Columbia 8-1-1 callers who are advised by a nurse to seek urgent medical care can be referred to virtual physicians (VPs) for supplemental assessment and advice. Prior research indicates callers' subsequent health service use may diverge from VP advice. We sought to 1) estimate concordance between VP advice and subsequent health service use, and 2) identify factors associated with concordance to understand potential drivers of discordant cases. METHODS: We linked relevant provincial administrative databases to obtain inpatient, outpatient, and emergency service use by callers. We developed operational definitions of concordance collaboratively with researcher, patient, VP, and management perspectives. We used Kaplan-Meier curves to describe health service use post-VP consultation and Cox regression to estimate the association of caller factors (rurality, demography, attachment to primary care) and call factors (reason, triage level, time of day) with concordance as hazard ratios. RESULTS: We analyzed 17,188 calls from November 16, 2020 to April 30, 2021. Callers advised to attend an emergency department (ED) immediately were the most concordant (73%) while concordance was lowest for those advised to seek Family Physician (FP) care either immediately (41%) or within 7 days (47%). Callers unattached to FPs were less likely to schedule an FP visit (hazard ratio = 0.76 [95%CI: 0.68-0.85]). Rural callers were less likely to attend an ED within 48 h when advised to go immediately (0.53 [95%CI:0.46-0.61]) compared to urban callers. Rural callers advised to see an FP, either immediately (1.28 [95%CI:1.01-1.62]) or within 7 days (1.23 [95%CI: 1.11-1.37]), were more likely to do so than urban callers. INTERPRETATION: Concordance between VP advice and subsequent caller health service use varies substantially by category of advice and caller rurality. Concordance with advice to "Go to ED" is high overall but to access primary care is below 50%, suggesting potential issues with timely access to FP care. Future research from a patient/caller centered perspective may reveal additional barriers and facilitators to concordance.

Health system use and outcomes of urgently triaged callers to a nurse-managed telephone service for provincial health information after initiation of supplemental virtual physician assessment: a descriptive study.

BACKGROUND: British Columbia's 8-1-1 telephone service connects callers with nurses for health care advice. As of Nov. 16, 2020, callers advised by a registered nurse to obtain in-person medical care can be subsequently referred to virtual physicians. We sought to determine health system use and outcomes of 8-1-1 callers urgently triaged by a nurse and subsequently assessed by a virtual physician. METHODS: We identified callers referred to a virtual physician between Nov. 16, 2020, and Apr. 30, 2021. After assessment, virtual physicians assigned callers to 1 of 5 triage dispositions (i.e., go to emergency department [ED] now, see primary care provider within 24 hours, schedule an appointment with a health care provider, try home treatment, other). We linked relevant administrative databases to ascertain subsequent health care use and outcomes. RESULTS: We identified 5937 encounters with virtual physicians involving 5886 8-1-1 callers. Virtual physicians advised 1546 callers (26.0%) to go to the ED immediately, of whom 971 (62.8%) had 1 or more ED visits within 24 hours. Virtual physicians advised 556 (9.4%) callers to seek primary care within 24 hours, of whom 132 (23.7%) had primary care billings within 24 hours. Virtual physicians advised 1773 (29.9%) callers to schedule an appointment with a health care provider, of whom 812 (45.8%) had primary care billings within 7 days. Virtual physicians advised 1834 (30.9%) callers to try a home treatment, of whom 892 (48.6%) had no health system encounters over the next 7 days. Eight (0.1%) callers died within 7 days of assessment with a virtual physician, 5 of whom were advised to go to the ED immediately. Fifty-four (2.9%) callers with a "try home treatment" disposition were admitted to hospital within 7 days of a virtual physician assessment, and no callers who were advised home treatment died. INTERPRETATION: This Canadian study evaluated health service use and outcomes arising from the addition of virtual physicians to a provincial health information telephone service. Our findings suggest that supplementation of this service with an assessment from a virtual physician safely reduces the overall proportion of callers advised to seek urgent in-person visits.

College complaints against resident physicians in Canada: a retrospective analysis of Canadian Medical Protective Association data from 2013 to 2017.

BACKGROUND: An understanding of regulatory complaints against resident physicians is important for practice improvement. We describe regulatory college complaints against resident physicians using data from the Canadian Medical Protective Association (CMPA). METHODS: We conducted a retrospective analysis of college complaint cases involving resident doctors closed by the CMPA, a mutual medicolegal defence organization for more than 100 000 physicians, representing an estimated 95% of Canadian physicians. Eligible cases were those closed between 2008 and 2017 (for time trends) or between 2013 and 2017 (for descriptive analyses). To explore the characteristics of college cases, we extracted the reason for complaint, the case outcome, whether the complaint involved a procedure, and whether the complaint stemmed from a single episode or multiple episodes of care. We also conducted a 10-year trend analysis of cases closed from 2008 to 2017, comparing cases involving resident doctors with cases involving only nonresident physicians. RESULTS: Our analysis included 142 cases that involved 145 patients. Over the 10-year period, college complaints involving residents increased significantly (p = 0.003) from 5.4 per 1000 residents in 2008 to 7.9 per 1000 in 2017. While college complaints increased for both resident and nonresident physicians over the study period, the increase in complaints involving residents was significantly lower than the increase across all nonresident CMPA members (p < 0.001). For cases from the descriptive analysis (2013-2017), the top complaint was deficient patient assessment (69/142, 48.6%). Some patients (22/145, 15.2%) experienced severe outcomes. Most cases (135/142, 97.9%) did not result in severe physician sanctions. Our classification of complaints found 106 of 163 (65.0%) involved clinical problems, 95 of 163 (58.3%) relationship problems (e.g., communication) and 67 of 163 (41.1%) professionalism problems. In college decisions, 36 of 163 (22.1%) had a classification of clinical problem, 66 of 163 (40.5%) a patient-physician relationship problem and 63 of 163 (38.7%) a professionalism problem. In 63 of 163 (38.7%) college decisions, the college had no criticism. INTERPRETATION: Problems with communication and professionalism feature prominently in resident college complaints, and we note the potential for mismatch between patient and health care provider perceptions of care. These results may direct medical education to areas of potential practice improvement.

Integration of virtual physician visits into a provincial 8-1-1 health information telephone service during the COVID-19 pandemic: a descriptive study of HealthLink BC Emergency iDoctor-in-assistance (HEiDi).

BACKGROUND: British Columbia, like many jurisdictions, has a health information telephone service (8-1-1) to provide callers with information by registered nurses and help them decide whether to attend an emergency department or primary care clinic, or manage their concern at home. We describe a new service, HealthLink BC Emergency iDoctor-in-assistance (HEiDi), that partnered physicians available by videoconferencing with 8-1-1 registered nurses to support callers. METHODS: From Apr. 6 to Aug. 2, 2020, all callers to the 8-1-1 telephone service (available to anyone in BC) categorized as "seek care within 24 hours" by registered nurses were eligible for referral to HEiDi. HEiDi physicians ("virtual physicians") connected directly with callers via desktop videoconferencing software, assessed their health complaint, provided advice and suggested care disposition. We conducted a descriptive study and collected demographic characteristics, health concern and disposition determined by the virtual physician. RESULTS: HEiDi virtual physicians provided 7687 consultations. Most patients (n = 4439, 57.8%) were in the 20-64 age range, and 4814 (62.9%) were female. Common health concerns were related to gastroenterology (n = 1275, 16.6%), respiratory (n = 877, 11.4%) and dermatology (n = 874, 11.4%). From the 7531 calls with available data, 2548 (33.8%) callers were advised to attempt home treatment, 2885 (38.3%) to contact a primary care physician within 1 week, 1131 (15.0%) to attend an emergency department immediately and 538 (7.1%) to attend their primary provider now. INTERPRETATION: We found that virtual physicians were able to advise nearly 3 out of 4 (72.1%) patients away from in-person emergency or clinic assessment and 1 in 7 (15.0%) to seek immediate emergency department care. Virtual physicians can provide an effective complement to a provincial health telephone system.

Process and findings informing the development of a provincial emergency medicine network.

We describe the process undertaken to inform the development of the recently launched British Columbia (BC) Emergency Medicine Network (EM Network). Five methods were undertaken: (1) a scoping literature review, (2) a survey of BC emergency practitioners and EM residents, (3) key informant interviews, (4) focus groups in sites across BC, and (5) establishment of a brand identity. There were 208 survey respondents: 84% reported consulting Internet resources once or more per emergency department shift; however, 26% reported feeling neutral, somewhat unsatisfied, or very unsatisfied with searching for information on the Internet to support their practice. Enthusiasm was expressed for envisioned EM Network resources, and the key informant interviews and focus group results helped identify and refine key desired components of the EM Network. In describing this, we provide guidance and lessons learned for health leaders and others who aspire to establish similar clinical networks, whether in EM or other medical disciplines.

Use of personal mobile devices to record patient data by Canadian emergency physicians and residents.

OBJECTIVE: Use of personal mobile devices to record patient data appears to be increasing, but remains poorly studied. We sought to determine the extent and reasons that Canadian emergency physicians (EPs) and emergency medicine residents use personal mobile devices to record patient data in the emergency department (ED). METHODS: A national survey was distributed to Canadian EPs and residents between 27/02/17 and 23/03/17. This captured demographics, frequency, and purpose of personal mobile device use to record patient data in the ED. It also asked about obtaining consent, security of information, implications for patient care, and knowledge of relevant regulations. RESULTS: The response rate was 23.1% (406 participants). A third (31.5%) reported using personal mobile devices to record patient data. Most (78.1%) did so more than once a month, and 7.0% did so every shift. Reasons cited included beliefs that using personal mobile devices to record patient data improves care by consultants (36.7%), expedites care (31.3%), and advances medical education (32.8%). Consent was rarely or never documented and a minority of participants (10.9%) indicated they did not obtain consent. More than half of participants (53.2%) reported being unaware of applicable regulations. CONCLUSIONS: This is the first Canadian study on the use of personal mobile devices to record patient data in the ED. Our findings demonstrate current practice may risk privacy breaches. Personal mobile device use to record patient data in the ED is common and Canadian EPs and residents believe that this practice enhances patient care.

OBJECTIF: L'utilisation des appareils mobiles personnels (AMP) pour l'enregistrement de données sur les malades semble de plus en plus fréquente, mais elle a été peu examinée jusqu'à maintenant. Aussi l'étude visait-elle à déterminer l'étendue de la pratique et les raisons pour lesquelles les médecins d'urgence (MU) et les résidents dans le domaine, au Canada, utilisent les AMP pour enregistrer des données sur les malades au service des urgences (SU). MÉTHODE: Un questionnaire d'enquête nationale a été envoyé au MU et aux résidents en la matière, au Canada, entre le 2 février 2017 et le 23 mars 2017. On a ainsi recueilli des données démographiques, de même que des renseignements sur la fréquence de la pratique et les raisons motivant l'utilisation des AMP pour la collecte de données sur les malades au SU. Des questions portaient aussi sur l'obtention du consentement, la sécurité de l'information, la portée de l'acte sur les soins aux malades et la connaissance de la réglementation applicable. RÉSULTATS: Le taux de réponse a atteint 23,1% (406 participants). Un tiers (31,5%) des répondants ont indiqué faire usage d'AMP pour enregistrer des données sur les malades. La plupart (78,1%) les utilisaient plus d'une fois par mois et 7,0%, à toutes les périodes de travail. Les raisons invoquées le plus souvent comprenaient l'opinion selon laquelle l'utilisation des AMP pour l'enregistrement de données sur les malades améliorait les soins par les consultants (36,7%), accélérait la prestation de soins (31,3%) et faisait progresser la formation médicale (32,8%). Le consentement était rarement documenté, voire jamais, et une minorité de répondants (10,9%) ont indiqué ne pas avoir obtenu le consentement des patients. Plus de la moitié des participants (53,2%) ont déclaré ne pas être courant de l'existence de règlements applicables. CONCLUSION: Il s'agit là de la première étude sur l'utilisation des AMP au Canada pour l'enregistrement de données sur les malades au SU. D'après les résultats de l'enquête, la pratique pourrait comporter des risques d'atteinte à la vie privée. L'usage des AMP pour l'enregistrement de données sur les malades au SU est courant, et les MU comme les résidents sont d'avis que la pratique améliore les soins aux malades.

The bougie and first-pass success in the emergency department: Journal Club review.

CLINICAL QUESTION: Is bougie use associated with increased first-pass success in emergency department (ED) intubations?Article chosen: Driver et al. The Bougie and First-Pass Success in the Emergency Department. Annals of Emerg Med 2017;70(4):473-478. OBJECTIVE: To compare data and assess whether bougie use is independently associated with first-pass success in ED intubations.

Application of quality improvement analytic methodology in emergency medicine research: A comparative evaluation.

OBJECTIVE: Quality improvement (QI) analytic methodology is rarely encountered in the emergency medicine literature. We sought to comparatively apply QI design and analysis techniques to an existing data set, and discuss these techniques as an alternative to standard research methodology for evaluating a change in a process of care. METHODS: We used data from a previously published randomized controlled trial on triage-nurse initiated radiography using the Ottawa ankle rules (OAR). QI analytic tools were applied to the data set from this study and evaluated comparatively against the original standard research methodology. RESULTS: The original study concluded that triage nurse-initiated radiographs led to a statistically significant decrease in mean emergency department length of stay. Using QI analytic methodology, we applied control charts and interpreted the results using established methods that preserved the time sequence of the data. This analysis found a compelling signal of a positive treatment effect that would have been identified after the enrolment of 58% of the original study sample, and in the 6th month of this 11-month study. CONCLUSIONS: Our comparative analysis demonstrates some of the potential benefits of QI analytic methodology. We found that had this approach been used in the original study, insights regarding the benefits of nurse-initiated radiography using the OAR would have been achieved earlier, and thus potentially at a lower cost. In situations where the overarching aim is to accelerate implementation of practice improvement to benefit future patients, we believe that increased consideration should be given to the use of QI analytic methodology.

Reasons and outcomes for patients receiving ICS/LABA agents prior to, and one month after, emergency department presentations for acute asthma.

Objective: Asthma is a common emergency department (ED) presentation. This study examined factors associated with inhaled corticosteroids/long-acting beta-agonist (ICS/LABA) use; and management and outcomes before and after ED presentation. Methods: Secondary analysis of a prospective cohort study; adults treated for acute asthma in Canadian EDs underwent a structured interview before discharge and were followed-up four weeks later. Patients received oral corticosteroids (OCS) at discharge and, at physician discretion, most received ICS or ICS/LABA inhaled agents. Analyses focused on ICS/LABA vs "other" treatment groups at ED presentation. Results: Of 807 enrolled patients, 33% reported receiving ICS/LABA at ED presentation; 62% were female, median age was 31 years. Factors independently associated with ICS/LABA treatment prior to ED presentation were: having an asthma action plan; using an asthma diary/peak flow meter; influenza immunization; not using the ED as usual site for prescriptions; ever using OCS and currently using ICS. Patients were treated similarly in the ED and at discharge; however, relapse was higher in the ICS/LABA group, even after adjustment. Conclusion: One-third of patients presenting to the ED with acute asthma were already receiving ICS/LABA agents; this treatment was independently associated with preventive measures. While ICS/LABA management improves control of chronic asthma, patients using these agents who develop acute asthma reflect higher severity and increased risk of future relapse.

The British Columbia Emergency Medicine Network: A Paradigm Shift in a Provincial System of Emergency Care.

As generalists, emergency practitioners face challenges in providing state-of-the-art care owing to the broad spectrum of practice and the rapid rate of new knowledge generation. Networks have become increasingly prevalent in health care, and it was in this backdrop, and the resulting opportunity to advance evidence-informed emergency care in the Canadian province of British Columbia (BC), that a new "Emergency Medicine Network" (EM Network) was launched in 2017. The EM Network consists of four programs, each led by a physician with expertise and a track record in the domain: (1) Clinical Resources; (2) Innovation; (3) Continuing Professional Development; and (4) Real-time Support. This paper provides an overview of the EM Network, including its background, purpose, programs, anticipated evolution, and impact on the BC health care system.

Prediction and risk stratification of survival in accidental hypothermia requiring extracorporeal life support: An individual patient data meta-analysis.

BACKGROUND: Extra-corporeal life support (ECLS) is a life-saving intervention for patients with hypothermia induced cardiac arrest or severe cardiovascular instability. However, its application is highly variable due to a paucity of data in the literature to guide practice. Current guidelines and recommendations are based on expert opinion, single case reports, and small case series. Combining all of the published data in a patient-level analysis can provide a robust assessment of the influence of patient characteristics on survival with ECLS. OBJECTIVE: To develop a prediction model of survival with good neurologic outcome for accidental hypothermia treated with ECLS. METHODS: Electronic searches of PubMed, EMBASE, CINAHL were conducted with a hand search of reference lists and major surgical and critical care conference abstracts. Studies had to report the use of ECLS configured with a circuit, blood pump and oxygenator with an integrated heat exchanger. Randomized and observational studies were eligible for inclusion. Non-human, non-English and review manuscripts were deemed ineligible. Study authors were requested to submit patient level data when aggregate or incomplete individual patient data was provided in a study. Survival with good neurologic outcome was categorized for patients to last follow-up based on the reported scores on the Cerebral Performance Category (1 or 2), Glasgow Outcome Scale (4 or 5) and Pediatric Overall Performance Category (1 or 2). A one-stage, individual patient data meta-analysis was performed with a mixed-effects multi-level logistic regression model reporting odds ratio (OR) with a 95% confidence interval (CI). RESULTS: Data from 44 observational studies and 40 case reports (n = 658) were combined and analyzed to identify independent predictors of survival with good neurologic outcome. The survival rate with good neurologic outcome of the entire cohort was 40.3% (265 of 658). ECLS rewarming rate (OR: 0.93; 95% CI: 0.88, 0.98; p = .007), female gender (OR: 2.78; 95% CI: 1.69, 4.58; p < 0.001), asphyxiation (OR: 0.19; 95% CI: 0.11, 0.35; p < 0.001) and serum potassium (OR: 0.62; 95% CI: 0.53, 0.73; p < 0.001) were associated with survival with a good neurologic outcome. The logistic regression model demonstrated excellent discrimination (c-statistic: 0.849; 95% CI: 0.823, 0.875). CONCLUSIONS: The use of extracorporeal life support in the treatment of hypothermic cardiac arrest provides a favourable chance of survival with good neurologic outcome. When used in a weighted scoring system, asphyxiation, serum potassium and gender can help clinicians prognosticate the benefit of resuscitating hypothermic patients with ECLS.

Relationship between Canadian medical school student career interest in emergency medicine and postgraduate training disposition.

BACKGROUND: Canada has two independent routes of emergency medicine (EM) training and certification. This unique situation may encourage medical students with EM career aspirations to apply to family medicine (FM) residencies to subsequently acquire College of Family Physicians of Canada (CFPC) training and certification in EM. We sought answers to the following: 1) Are medical students who indicate EM as their top career choice on medical school entry, and then complete a FM residency, more likely to undertake subsequent CFPC-EM training than other FM residents who did not indicate EM as their top career choice; and 2) What are the characteristics of medical students in four predefined groups, based upon their early interest in EM as a career and ultimate postgraduate training disposition. METHODS: Data were accessed from a survey of medical students in 11 medical school classes from eight Canadian universities and anonymously linked to information from the Canadian Residency Matching Service between 2006 and 2009. RESULTS: Of 1036 participants, 63 (6.1%) named EM as their top career choice on medical school entry. Of these, 10 ultimately matched to a Royal College of Physicians and Surgeons of Canada (RCPSC) EM residency program, and 24 matched to a FM residency program, nine of whom went on to do a one-year CFPC-EM residency program in contrast to 57 of the remaining 356 students matching to FM residency programs who did not indicate EM was their top career choice (37.5% vs 16.0%, p=0.007). Statistically significant attitudinal differences related to the presence or absence of EM career interest on medical school entry were found. CONCLUSION: Considering those who complete CFPC-EM training, a greater proportion indicate on admission to medical school that EM is their top career choice compared to those who do not. Moreover, students with an early career interest in EM are similar for several attitudinal factors independent of their ultimate postgraduate training disposition. Given the current issues and challenges facing FM and EM, these findings have implications that merit consideration by both the CFPC and the RCPSC.
