Implementation, Clinical Benefit and Safety of a D-Dimer-Focused Pulmonary Embolism Testing Pathway in the Emergency Department.

STUDY OBJECTIVE: Computed tomography pulmonary angiogram (CTPA) is overused during pulmonary embolism (PE) testing in the emergency department (ED), whereas prediction rules and D-dimer are underused. We report the adherence, clinical benefit, and safety of a D-dimer-only strategy to guide need for PE imaging in the ED. METHODS: This was a prospective multicenter implementation study in 2 EDs with historical and external controls. Patients with suspected PE underwent D-dimer testing and imaging (CTPA or ventilation-perfusion scan) when D-dimer levels were 500 ng/mL or more. PE was ruled out if D-dimer was less than 500 ng/mL or with negative imaging. The primary implementation outcome was the proportion of patients tested for PE in adherence with the pathway. The primary clinical benefit outcome was the proportion of patients tested for PE who received pulmonary imaging. The primary safety outcome was diagnosis of PE in the 30 days following negative PE testing postimplementation. RESULTS: Between January 2018 and June 2021, 16,155 patients were tested for PE, including 33.4% postimplementation, 30.7% preimplementation, and 35.9% in an external control site. Adherence with the D-dimer-only pathway was 97.6% (adjusted odds ratio (aOR) post- versus preimplementation 5.26 (95% confidence interval 1.70 to 16.26). There was no effect on the proportion undergoing PE imaging. Imaging yield increased aOR 4.89 (1.17 to 20.53). Two cases of PE (0.04%; 0.01% to 0.16%) were diagnosed within 30 days. CONCLUSION: In this Canadian ED study, the uptake of a D-dimer-only PE testing strategy was high. Implementation was associated with higher imaging yield and a D-dimer level of less than 500 ng/mL safely excluded PE.

The inseparability of context and clinical reasoning.

Early descriptions of clinical reasoning have described a dual process model that relies on analytical or nonanalytical approaches to develop a working diagnosis. In this classic research, clinical reasoning is portrayed as an individual-driven cognitive process based on gathering information from the patient encounter, forming mental representations that rely on previous experience and engaging developed patterns to drive working diagnoses and management plans. Indeed, approaches to patient safety, as well as teaching and assessing clinical reasoning focus on the individual clinician, often ignoring the complexity of the system surrounding the diagnostic process. More recent theories and evidence portray clinical reasoning as a dynamic collection of processes that takes place among and between persons across clinical settings. Yet, clinical reasoning, taken as both an individual and a system process, is insufficiently supported by theories of cognition based on individual clinicals and lacks the specificity needed to describe the phenomenology of clinical reasoning. In this review, we reinforce that the modern healthcare ecosystem - with its people, processes and technology - is the context in which health care encounters and clinical reasoning take place.

Validating the Emergency Department Avoidability Classification (EDAC): A cluster randomized single-blinded agreement study.

INTRODUCTION: The Emergency Department Avoidability Classification (EDAC) retrospectively classifies emergency department (ED) visits that could have been safely managed in subacute primary care settings, but has not been validated against a criterion standard. A validated EDAC could enable accurate and reliable quantification of avoidable ED visits. We compared agreement between the EDAC and ED physician judgements to specify avoidable ED visits. MATERIALS AND METHODS: We conducted a cluster randomized, single-blinded agreement study in an academic hospital in Hamilton, Canada. ED visits between January 1, 2019, and December 31, 2019 were clustered based on EDAC classes and randomly sampled evenly. A total of 160 ED visit charts were randomly assigned to ten participating ED physicians at the academic hospital for evaluation. Physicians judged if the ED visit could have been managed appropriately in subacute primary care (an avoidable visit); each ED visit was evaluated by two physicians independently. We measured interrater agreement between physicians with a Cohen's kappa and 95% confidence intervals (CI). We evaluated the correlation between the EDAC and physician judgements using a Spearman rank correlation and ordinal logistic regression with odds ratios (ORs) and 95% CIs. We examined the EDAC's precision to identify avoidable ED visits using accuracy, sensitivity and specificity. RESULTS: ED physicians agreed on 139 visits (86.9%) with a kappa of 0.69 (95% CI 0.59-0.79), indicating substantial agreement. Physicians judged 96.2% of ED visits classified as avoidable by the EDAC as suitable for management in subacute primary care. We found a high correlation between the EDAC and physician judgements (0.64), as well as a very strong association to classify avoidable ED visits (OR 80.0, 95% CI 17.1-374.9). The EDACs avoidable and potentially avoidable classes demonstrated strong accuracy to identify ED visits suitable for management in subacute care (82.8%, 95% CI 78.2-86.8). DISCUSSION: The EDAC demonstrated strong evidence of criterion validity to classify avoidable ED visits. This classification has important potential for accurately monitoring trends in avoidable ED utilization, measuring proportions of ED volume attributed to avoidable visits and informing interventions intended at reducing ED use by patients who do not require emergency or life-saving healthcare.

GridlockED as an Intervention for Nurses (GAAIN) Study.

BACKGROUND: GridlockED (The Game Crafter, LLC) is a serious game that was developed to teach challenges that face nursing and medical professionals in the emergency department (ED). However, few studies have explored nurses' perceptions of the utility, fidelity, acceptability, and applicability of the serious game modality. This study examined how ED nurses view GridlockED as a continuing education platform. METHOD: This single-center observational study explored how nurses engage with and respond to Grid-lockED. The convenience sample included participants recruited from a local continuing nursing education day. Participants completed a presurvey, engaged in a full game play session with the GridlockED game for approximately 45 minutes, and immediately completed a post-game play survey. RESULTS: Of the 48 participants (11 male, 37 female; 44 of 48 were RNs), most (91%) agreed that the workflow reflected in the game was equivalent to the flow in a typical ED. Almost all (96%) found the cases in the game reflective of real ED patients, and most (92%) found the game a useful educational tool to prepare new nurses to transition into the ED environment. CONCLUSION: The GridlockED game shows potential as a serious game to support nursing education, particularly for new ED nurse orientation and transition to ED practice.

Was Virtual Care as Safe as In-Person Care? Analyzing Patient Outcomes at Seven and Thirty Days in Ontario during the COVID-19 Pandemic.

In 2020, almost overnight, the paradigm for healthcare interactions changed in Ontario. To limit person-to-person transmission of COVID-19, the norm of in-person interactions shifted to virtual care. While this shift was part of broader public health measures and an acknowledgment of patient and societal concerns, it also represented a change in care modalities that had the potential to affect the quality of care provided, as well as short- and long-term patient outcomes. While public policy decisions were being made to moderate the use of virtual care at the end of the declared pandemic, a thorough analysis of short-term patient outcomes was needed to quantify the impact of virtual care on the population of Ontario.

Health care utilization and outcomes of patients seen by virtual urgent care versus in-person emergency department care.

BACKGROUND: Virtual urgent care (VUC) is intended to support diversion of patients with low-acuity complaints and reduce the need for in-person emergency department visits. We aimed to describe subsequent health care utilization and outcomes of patients who used VUC compared with similar patients who had an in-person emergency department visit. METHODS: We used patient-level encounter data that were prospectively collected for patients using VUC services provided by 14 pilot programs in Ontario, Canada. We linked the data to provincial administrative databases to identify subsequent 30-day health care utilization and outcomes. We defined 2 subgroups of VUC users; those with a documented prompt referral to an emergency department by a VUC provider, and those without. We matched patients in each cohort to an equal number of patients presenting to an emergency department in person, based on encounter date, medical concern and the logit of a propensity score. For the subgroup of patients not promptly referred to an emergency department, we matched patients to those who were seen in an emergency department and then discharged home. RESULTS: Of the 19 595 patient VUC visits linked to administrative data, we matched 2129 patients promptly referred to the emergency department by a VUC provider to patients presenting to the emergency department in person. Index visit hospital admissions (9.4% v. 8.7%), 30-day emergency department visits (17.0% v. 17.5%), and hospital admissions (12.9% v. 11.0%) were similar between the groups. We matched 14 179 patients who were seen by a VUC provider with no documented referral to the emergency department. Patients seen by VUC were more likely to have a subsequent in-person emergency department visit within 72 hours (13.7% v. 7.0%), 7 days (16.5% v. 10.3%) and 30 days (21.9% v. 17.9%), but hospital admissions were similar within 72 hours (1.1% v. 1.3%), and higher within 30 days for patients who were discharged home from the emergency department (2.6% v. 3.4%). INTERPRETATION: The impact of the provincial VUC pilot program on subsequent health care utilization was limited. There is a need to better understand the inherent limitations of virtual care and ensure future virtual providers have timely access to in-person outpatient resources, to prevent subsequent emergency department visits.

Development of a machine learning-based acuity score prediction model for virtual care settings.

OBJECTIVE: Healthcare is increasingly digitized, yet remote and automated machine learning (ML) triage prediction systems for virtual urgent care use remain limited. The Canadian Triage and Acuity Scale (CTAS) is the gold standard triage tool for in-person care in Canada. The current work describes the development of a ML-based acuity score modelled after the CTAS system. METHODS: The ML-based acuity score model was developed using 2,460,109 de-identified patient-level encounter records from three large healthcare organizations (Ontario, Canada). Data included presenting complaint, clinical modifiers, age, sex, and self-reported pain. 2,041,987 records were high acuity (CTAS 1-3) and 416,870 records were low acuity (CTAS 4-5). Five models were trained: decision tree, k-nearest neighbors, random forest, gradient boosting regressor, and neural net. The outcome variable of interest was the acuity score predicted by the ML system compared to the CTAS score assigned by the triage nurse. RESULTS: Gradient boosting regressor demonstrated the greatest prediction accuracy. This final model was tuned toward up triaging to minimize patient risk if adopted into the clinical context. The algorithm predicted the same score in 47.4% of cases, and the same or more acute score in 95.0% of cases. CONCLUSIONS: The ML algorithm shows reasonable predictive accuracy and high predictive safety and was developed using the largest dataset of its kind to date. Future work will involve conducting a pilot study to validate and prospectively assess reliability of the ML algorithm to assign acuity scores remotely.

"It saved me from the emergency department": A qualitative study of patient experience of virtual urgent care in Ontario.

INTRODUCTION: In response to the COVID-19 pandemic, the Ontario Ministry of Health introduced a pilot program of 14 virtual urgent care (VUC) initiatives across the province to encourage physical distancing and provision of care by telephone and video-enabled visits. The implementation of the VUC pilot is currently being evaluated by an external academic team. The objective of this study was to understand patient experiences with VUC to determine barriers and facilitators to optimal virtual care as it rapidly expands during the current pandemic and beyond. METHOD: The qualitative component of the evaluation used one-on-one telephone interviews with patients, families, providers, and program administrators as the main method of data collection. Patient and family participants were invited to participate by the triage nurse after their VUC visit. Data analysis, using thematic analysis, occurred in conjunction with data collection to monitor emerging themes and areas for further exploration. RESULTS: Between April and October 2021, we completed 14 patient and/or family interviews from a representative cross-section of 6 pilot sites. Participants had a range of presenting complaints including infection, injury, medication side effects, and abdominal pain. The vast majority of participants were female (90%), and 70% were VUC patients themselves. Our analysis identified three key themes in the data which characterise patient and family member experience with VUC: a) emphasis on access to the ED; b) efficiency and quality of care; c) obtaining reassurance and next steps. CONCLUSION: Virtual care options are valued by patients and families; however, the nature of care needed by those accessing VUC and who can best provide that care needs to be evaluated to position it for sustainability. Understanding how virtual care performs from both a provider and patient perspective during the current crisis has implications for designing alternative care options beyond the COVID-19 pandemic.

Quantifying the escalating impact of paramedic transported emergency department visits for opioid-related conditions in Ontario, Canada: A population-based cohort study.

INTRODUCTION: While overdoses comprise the majority of opioid research, the comprehensive impact of the opioid crisis on emergency departments (EDs) and paramedic services has not been reported. We examined temporal changes in population-adjusted incidence rates of ED visits and paramedic transports due to opioid-related conditions. MATERIALS AND METHODS: We conducted a population-based cohort study of all ED visits in the National Ambulatory Care Reporting System from January 1, 2009 to December 31, 2019 in Ontario, Canada. We included all patients with a primary diagnosis naming opioids as the underlying cause for the visit, without any other drugs or substances. We clustered geographic regions using Local Health Integration Network boundaries. Descriptive statistics, incidence rate ratios (IRR) and 95% confidence intervals (CIs) were calculated to analyze population-adjusted temporal changes. RESULTS: Overall, 86,403 ED visits were included in our study. Incidence of opioid-related ED visits increased by 165% in the study timeframe, with paramedic transported patients increasing by 429%. Per 100,000 residents, annual ED visits increased from 40.4 to 97.2, and paramedic transported patients from 12.1 to 67.9. The proportion of opioid-related ED visits transported by paramedics increased from 35.0% to 69.9%. The medical acuity of opioid-related ED visits increased throughout the years (IRR 6.8. 95% CI 5.9-7.7), though the proportion of discharges remained constant (~75%). The largest increases in ED visits and paramedic transports were concentrated to urbanized regions. DISCUSSION: Opioid-related ED visits and paramedic transports increased substantially between 2009 and 2019. The proportion of ED visits transported by paramedics doubled. Our findings could provide valuable support to health stakeholders in implementing timely strategies aimed at safely reducing opioid-related ED visits. The increased use of paramedics followed by high rates of ED discharge calls for exploration of alternative care models within paramedic systems, such as direct transport to specialized substance abuse centres.

Evaluating emergency department transfers from urgent care centres: insights for paramedic integration with subacute healthcare.

OBJECTIVE: Paramedics redirecting non-emergent patients from emergency departments (EDs) to urgent care centres is a new and forthcoming strategy to reduce overcrowding and improve primary care integration. Which patients are likely not suitable for paramedic redirection are unknown. To describe and specify patients inappropriate for urgent care centres, we examined associations between patient characteristics and transfer to the ED after patients initially presented to an urgent care centre. METHODS: A population-based retrospective cohort study of all adult (≥18 years) visits to an urgent care centre from 1 April 2015 to 31 March 2020 in Ontario, Canada. Binary logistic regression was used to determine unadjusted and adjusted associations between patient characteristics and being transferred to an ED using OR and 95% CIs. We calculated the absolute risk difference for the adjusted model. RESULTS: A total of 1 448 621 urgent care visits were reported, with 63 343 (4.4%) visits transferred to an ED for definitive care. Being 65 years and older (OR 2.29, 95% CI 2.23 to 2.35), scored an emergent Canadian Triage and Acuity Scale of 1 or 2 (OR 14.27, 95% CI 13.45 to 15.12) and higher comorbidity count (OR 1.51, 95% CI 1.46 to 1.58) had added odds of association with being transferred out to an ED. CONCLUSION: Readily available patient characteristics were independently associated with interfacility transfers between urgent care centres and the ED. This study can support paramedic redirection protocol development, highlighting which patients may not be best suited for ED redirection.

The COVID-19 impact and characterization on substance use-related emergency department visits for adolescents and young adults in Canada: Practical implications.

RATIONALE: Coronavirus (COVID-19)-related stressors precipitated the mental health crisis and increased substance use in Canada and worldwide. As the pandemic continues to evolve, monitoring and updating substance use-related ED visit trends is essential to ensure the stability and quality of ED services under the prolonged pandemic timeline. AIMS AND OBJECTIVES: This study examined the trends and characterization of substance use-related ED visits during the pandemic among adolescents and young adults (aged 13-25 years) in Ontario, Canada. METHODS: Descriptive statistics and binary logistic regression analyses were conducted using population-based, repeated cross-sectional data. The volume, patient characteristics (age and sex) and hospital/ED visit features (triage to end time, timing of the visit, triage level and referral source) were compared before (2019) and during COVID-19 (2020 and 2021) by each substance type (alcohol, opioid, cannabis, sedatives, cocaine, stimulants and multiple psychoactive substances). RESULTS: Substance use-related ED visits decreased by 1.5 times during the pandemic compared to the prepandemic level. However, opioid-related ED visits continued to show an increasing trend and did not recover to the prepandemic level in 2021. Moreover, a significant increase in emergent/life-threatening triage levels (Canadian Triage and Acuity Scales 1 and 2) in substance-related ED visits is alarming (2019 = 36.8%, 2020 = 38.7% and 2021 = 38.4%). We also found a general decrease in weekend visits, overnight visits and visits on statutory holidays, and substance use-related ED patients tended to stay longer (over 6 h) in the ED during the pandemic. CONCLUSION: Our findings indicate unmet substance use treatment needs due to the limited accessibility and heightened threshold for ED visits during the pandemic. Providing access to substance treatment/programs outside ED is critical to reducing substance use-related complications presenting in the ED. Also, policies addressing the pandemic-related complexities in the ED and Health Human Resource challenges are warranted.

Demographic characteristics, outcomes and experience of patients using virtual urgent care services from 14 emergency department led sites in Ontario.

INTRODUCTION: As part of the COVID-19 pandemic response, the Ontario Ministry of Health funded a virtual care pilot program intended to support emergency department (ED) diversion of patients with low acuity complaints and reduce the need for face-to-face contact. The objective was to describe the demographic characteristics, outcomes and experience of patients using the provincial pilot program. METHODS: This was a prospective cohort study of patients using virtual care services provided by 14 ED-led pilot sites from December 2020 to September 2021. Patients who completed a virtual visit were invited by email to complete a standardized, 25-item online survey, which included questions related to satisfaction and patient-reported outcome measures. RESULTS: There were 22,278 virtual visits. When patients were asked why they contacted virtual urgent care, of the 82.7% patients who had a primary care provider, 31.0% said they could not make a timely appointment with their family physician. Rash, fever, abdominal pain, and COVID-19 vaccine queries represented 30% of the presenting complaints. Of 19,613 patients with a known disposition, 12,910 (65.8%) were discharged home and 3,179 (16.2%) were referred to the ED. Of the 2,177 survey responses, 94% rated their overall experience as 8/10 or greater. More than 80% said they had answers to all the questions they had related to their health concern, believed they were able to manage the issue, had a plan they could follow, and knew what to do if the issue got worse or came back. CONCLUSIONS: Many presenting complaints were low acuity, and most patients had a primary care provider, but timely access was not available. Future work should focus on health equity to ensure virtual care is accessible to underserved populations. We question if virtual urgent care can be safely and more economically provided by non-emergency physicians.

RéSUMé: INTRODUCTION: Dans le cadre de la réponse à la pandémie de COVID-19, le ministère de la Santé de l'Ontario a financé un programme pilote de soins virtuels visant à soutenir la réorientation vers les services d'urgence des patients présentant des problèmes de faible acuité et à réduire le besoin de contact en personne. L'objectif était de décrire les caractéristiques démographiques, les résultats et l'expérience des patients utilisant le programme pilote provincial. MéTHODES: Il s'agissait d'une étude de cohorte prospective de patients utilisant des services de soins virtuels fournis par 14 sites pilotes dirigés par des services d'urgence, de décembre 2020 à septembre 2021. Les patients qui ont effectué une visite virtuelle ont été invités par courriel à répondre à une enquête en ligne standardisée de 25 questions, qui comprenait des questions relatives à la satisfaction et aux résultats rapportés par les patients. RéSULTATS: Il y a eu 22 278 visites virtuelles. Lorsqu'on a demandé aux patients pourquoi ils avaient contacté les soins urgents virtuels, sur les 82,7 % de patients qui avaient un prestataire de soins primaires, 31,0 % ont répondu qu'ils n'avaient pas pu obtenir un rendez-vous en temps voulu avec leur médecin de famille. Les éruptions cutanées, la fièvre, les douleurs abdominales et les interrogations sur le vaccin COVID-19 représentaient 30 % des plaintes présentées. Sur les 19 613 patients dont la disposition était connue, 12 910 (65,8 %) ont été renvoyés chez eux et 3 179 (16,2 %) ont été orientés vers les urgences. Sur les 2 177 réponses à l'enquête, 94 % ont attribué une note de 8/10 ou plus à leur expérience globale. Plus de 80 % d'entre eux ont déclaré avoir obtenu des réponses à toutes les questions qu'ils se posaient sur leur problème de santé, se croire capables de le gérer, avoir un plan qu'ils pouvaient suivre et savoir quoi faire si le problème s'aggravait ou revenait. CONCLUSIONS: De nombreuses plaintes présentées étaient de faible acuité, et la plupart des patients avaient un fournisseur de soins primaires, mais l'accès en temps opportun n'était pas disponible. Les travaux futurs devraient se concentrer sur l'équité en matière de santé pour s'assurer que les soins virtuels sont accessibles aux populations mal desservies et nous nous demandons si ces services peuvent être fournis en toute sécurité et de manière plus économique par des médecins non urgentistes.

Storage conditions, sample integrity, interferences, and a decision tool for investigating unusual high-sensitivity cardiac troponin results.

The current definition of high-sensitivity cardiac troponin (hs-cTn) assays is laboratory-based and their analytical attributes and characteristics have drawn significant attention in the literature at least partly due to the lower concentration cut-offs and changes in concentrations (i.e., deltas) employed in different algorithms and pathways to manage patient care. We propose that pre-analytical conditions such as sample type, storage conditions, and other interferences may also have a significant impact on hs-cTn concentrations and clinical management. The purpose of this literature review is to provide a summary of important pre-analytical and interference studies affecting hs-cTn concentrations. A breakdown of the literature for the major diagnostic companies providing core laboratory instrumentation (i.e., Abbott, Beckman, Ortho, Roche, and Siemens) is also provided. Finally, three cases are highlighted where knowledge of pre-analytical factors aids the hs-cTn clinically discordant investigations. This review highlights the importance of pre-analytical variables, especially storage condition, sample handling, and blood tubes used (i.e., sample type) when interpreting hs-cTn assays. Additional studies are needed to further elaborate on pre-analytical variables (i.e., centrifugation, sample type, stability) and interferences for all hs-cTn assays in clinical use, as knowledge of these variables may aid in hs-cTn clinically discordant investigations.

Validation of a classification to identify emergency department visits suitable for subacute and virtual care models: a randomised single-blinded agreement study protocol.

INTRODUCTION: Redirecting suitable patients from the emergency department (ED) to alternative subacute settings may assist in reducing ED overcrowding while delivering equivalent care. The Emergency Department Avoidance Classification (EDAC) was constructed to retrospectively classify ED visits that may have been suitable for safe management in a subacute or virtual clinical setting. The EDAC has established face and content validity but has not been tested against a reference standard as a criterion. OBJECTIVES: Our primary objective is to examine the agreement between the EDAC and ED physician judgements in retrospectively identifying ED visits suitable for subacute care management. Our secondary objective is to assess the validity of ED physicians' judgement as a criterion standard. Our tertiary objective is to examine how the ED physician's perception of a virtual ED care alternative correlates with the EDAC. METHODS AND ANALYSIS: A randomised single-centre, single-blinded agreement study. We will randomly select ED charts between 1 January and 31 December 2019 from an academic hospital in Hamilton, Canada. ED charts will be randomly assigned to participating ED physicians who will evaluate if this ED visit could have been managed appropriately and safely in a subacute and/or virtual model of care. Each chart will be reviewed by two physicians independently. We compute our needed sample size to be 79 charts. We will use kappa statistics to measure inter-rater agreement. A repeated measures regression model of physician ratings will provide variance estimates that we will use to assess the intraclass correlation of ED physician ratings and the EDAC. ETHICS AND DISSEMINATION: This study has been approved by the Hamilton Integrated Research Ethics Board (2022-14625). If validated, the EDAC may provide an ED-based classification to identify potentially avoidable ED visits, monitor ED visit trends, and proactively delineate those best suited for subacute or virtual care models.

Designs, facilitators, barriers, and lessons learned during the implementation of emergency department led virtual urgent care programs in Ontario, Canada.

Introduction: Virtual patient care has seen incredible growth since the beginning of the COVID-19 pandemic. To provide greater access to safe and timely urgent care, in the fall of 2020, the Ministry of Health introduced a pilot program of 14 virtual urgent care (VUC) initiatives across the province of Ontario. The objective of this paper was to describe the overall design, facilitators, barriers, and lessons learned during the implementation of seven emergency department (ED) led VUC pilot programs in Ontario, Canada. Methods: We assembled an expert panel of 13 emergency medicine physicians and researchers with experience leading and implementing local VUC programs. Each VUC program lead was asked to describe their local pilot program, share common facilitators and barriers to adoption of VUC services, and summarize lessons learned for future VUC design and development. Results: Models of care interventions varied across VUC pilot programs related to triage, staffing, technology, and physician remuneration. Common facilitators included local champions to guide program delivery, provincial funding support, and multi-modal marketing and promotions. Common barriers included behaviour change strategies to support adoption of a new service, access to high-quality information technology to support new workflow models that consider privacy, risk, and legal perspectives, and standardized data collection which underpin overall objective impact assessments. Conclusions: These pilot programs were rapidly implemented to support safe access to care and ED diversion of patients with low acuity issues during the COVID-19 pandemic. The heterogeneity of program implementation respects local autonomy yet may present challenges for sustainability efforts and future funding considerations.

Increased demand for paramedic transports to the emergency department in Ontario, Canada: a population-level descriptive study from 2010 to 2019.

PURPOSE: We examined changes in annual paramedic transport incidence over the ten years prior to COVID-19 in comparison to increases in population growth and emergency department (ED) visitation by walk-in. METHODS: We conducted a population-level cohort study using the National Ambulatory Care Reporting System from January 1, 2010 to December 31, 2019 in Ontario, Canada. We included all patients triaged in the ED who arrived by either paramedic transport or walk-in. We clustered geographical regions using the Local Health Integration Network boundaries. Descriptive statistics, rate ratios (RR), and 95% confidence intervals were calculated to explore population-adjusted changes in transport volumes. RESULTS: Overall incidence of paramedic transports increased by 38.3% (n = 264,134), exceeding population growth fourfold (9.4%) and walk-in ED visitation threefold (13.4%). Population-adjusted transport rates increased by 26.2% (rate ratio 1.26, 95% CI 1.26-1.27) compared to 3.4% for ED visit by walk-in (rate ratio 1.03, 95% CI 1.03-1.04). Patient and visit characteristics remained consistent (age, gender, triage acuity, number of comorbidities, ED disposition, 30-day repeat ED visits) across the years of study. The majority of transports in 2019 had non-emergent triage scores (60.0%) and were discharged home directly from the ED (63.7%). The largest users were persons aged 65 or greater (43.7%). The majority of transports occurred in urbanized regions, though rural and northern regions experienced similar paramedic transport growth rates. CONCLUSION: There was a substantial increase in the demand for paramedic transportation. Growth in paramedic demand outpaced population growth markedly and may continue to surge alongside population aging. Increases in the rate of paramedic transports per population were not bound to urbanized regions, but were province-wide. Our findings indicate a mounting need to develop innovative solutions to meet the increased demand on paramedic services and to implement long-term strategies across provincial paramedic systems.

RéSUMé: OBJECTIFS: Nous avons examiné l'évolution de l'incidence annuelle du transport paramédical au cours des dix années précédant la COVID-19 par rapport à l'augmentation de la croissance de la population et des visites à l'urgence en personne. MéTHODES: Nous avons mené une étude de cohorte au niveau de la population en utilisant le Système national d'information sur les soins ambulatoires du 1er janvier 2010 au 31 décembre 2019 en Ontario, au Canada. Nous avons inclus tous les patients triés aux urgences qui sont arrivés par transport paramédical ou sans rendez-vous. Nous avons regroupé les régions géographiques en utilisant les limites du Réseau local d'intégration des services de santé. Des statistiques descriptives, des rapports de taux (RR) et des intervalles de confiance à 95% ont été calculés pour examiner les variations des volumes de transport ajustées en fonction de la population. RéSULTATS: L'incidence globale des transports paramédicaux a augmenté de 38.3% (n = 264 134), soit quatre fois plus que la croissance démographique (9.4%) et trois fois plus que la fréquentation des urgences sans rendez-vous (13.4 %). Les taux de transport ajustés à la population ont augmenté de 26.2 % (ratio de taux 1.26, IC à 95% 1.26­1.27), contre 3.4 % pour la visite aux urgences sans rendez-vous (ratio de taux 1.03, IC à 95% 1.03­1.04). Les caractéristiques des patients et des visites sont restées constantes (âge, sexe, acuité du triage, nombre de comorbidités, disposition des urgences, visites répétées aux urgences à 30 jours) au cours des années d'étude. La majorité des transports en 2019 avaient des scores de triage non urgents (60.0 %) et ont été renvoyés chez eux directement du service d'urgence (63.7 %). Les plus grands utilisateurs étaient les personnes âgées de 65 ans ou plus (43.7 %). La majorité des transports ont eu lieu dans les régions urbanisées, bien que les régions rurales et du Nord aient connu des taux de croissance du transport paramédical similaires. CONCLUSION: Il y a eu une augmentation considérable de la demande de transport paramédical. La croissance de la demande de services paramédicaux a nettement dépassé la croissance de la population et pourrait continuer d'augmenter parallèlement au vieillissement de la population. Les augmentations du taux de transports paramédicaux par population n'étaient pas limitées aux régions urbanisées, mais s'étendaient à l'ensemble de la province. Nos constatations indiquent un besoin croissant d'élaborer des solutions novatrices pour répondre à la demande accrue de services paramédicaux et mettre en œuvre des stratégies à long terme dans l'ensemble des systèmes paramédicaux provinciaux.

What Faculty Want: Academic and Community Emergency Physicians' Perceptions of Learner Feedback.

Introduction Faculty development is often deployed by central medical schools, with little guidance from end-users. How and what faculty members can use to improve their performance requires a deeper understanding from this user group. This study aims to explore how faculty perceive learners' feedback about their performance as educators. Methods This study is an explanatory mixed-method research, wherein community- and academic-based emergency medicine faculty members from nine regional hospitals were surveyed about their perceptions of various outcome measures for faculty development. Selected participants were invited to follow-up interviews. We analyzed the physicians' perceptions toward teaching and performance feedback data based on faculty's gender, role as academic or community physician, and work experience. Results The quantitative phase has 104 participants, and 15 of these were followed up with interviews. The gender of faculty does not have statistical or practical differences regarding their perceptions of learner feedback. Type of practice contains meaningful insights about the perception of learner feedback although it does not have a statistical difference. Moreover, an inverse trend exists between the physicians' years of experience and their perceived value of learner feedback. Kruskal-Wallis test showed a significant difference in the faculty's experience level and their perceived value for the metric "quantity of feedback commentary compared to their peer group" (H(4) = 12.21, p = 0.02), specifically between junior and senior faculty (p = 0.007). Some faculty stated that experienced faculty may perceive they have a very well-established style. Conclusions Diversifying feedback sources and delivery may be useful for different groups of faculty members. Junior physicians are more interested in gaining feedback about the quantity of their written feedback to students compared to more senior physicians. Learner feedback holds promise to trigger continuous improvement in community sites for those who fall behind compared to the academic sites.
