The impact of performance feedback reports on physician ordering behavior in the use of computed tomography pulmonary angiography (CTPA).

PURPOSE: The increased utilization, and potential overutilization, of computed tomography pulmonary angiography (CTPA) is a well-recognized issue within emergency departments (EDs). The objective of this study is to determine the impact of performance feedback reports on CTPA ordering behavior among ED physicians. METHODS: We conducted a prospective study of the impact of individualized performance feedback reports on the ordering behavior of physicians working at two high-volume community EDs in Ontario, Canada. We generated individualized reports (or "Dashboards") for each ED physician containing detailed feedback and peer comparison for each physician's CTPA ordering. Our baseline pre-intervention period was January 1 to December 31, 2018, and our intervention period was January 1, 2019, to December 31, 2021. We tracked individual and group ordering behavior through the study period. Our primary outcomes are impact of feedback on (1) overall group ordering rate and (2) overall diagnostic yield. Secondary analysis was done to determine the impact of the intervention on those physicians with the highest CTPA utilization rate. RESULTS: There was no statistically significant difference in the diagnostic yield of the included physicians in either of the years of the intervention period. There was a statically significant increase in the utilization rate for CTPA from 2018 to 2020 and 2021 from 5.9 to 7.9 and 11.4 CTPAs per 1000 ED visits respectively (p < 0.5). CONCLUSION: Our study found no consistent significant impact of individualized feedback and peer comparison on physician ordering of CTPAs. This points to a potentially greater impact of environmental and institutional factors, as opposed to physician-targeted quality improvement measures, on physician ordering behavior.

CAEP 2021 Academic Symposium: recommendations for addressing racism and colonialism in emergency medicine.

PURPOSE: Racism and colonialism impact health, physician advancement, professional development and medical education in Canada. The Canadian Association of Emergency Physicians (CAEP) has committed to addressing inequities in health in their recent statement on racism. The objective of this project was to develop recommendations for addressing racism and colonialism in emergency medicine. METHODS: The authors, in collaboration with a 40 member working group, conducted a literature search, held a community consultation, solicited input from expert medical, academic and community advisors, conducted a national survey of emergency physicians, and presented draft recommendations at the 2021 CAEP Academic Symposium on Equity, Diversity and Inclusion for a live facilitated discussion with a post-session survey. RESULTS: Sixteen recommendations were generated in the areas of patient care, hospital and departmental commitment to Equity, Diversity, and Inclusion, physician advancement, and professional development and medical education. CONCLUSION: Emergency physicians are uniquely positioned to promote equity at each encounter with patients, peers and learners. The 16 recommendations presented here are practical steps to countering racism and colonialism everyday in emergency medicine.

RéSUMé: OBJECTIF: Le racisme et le colonialisme ont une incidence sur la santé, l'avancement des médecins, le développement professionnel et l'éducation médicale au Canada. L'Association canadienne des médecins d'urgence (ACMU) s'est engagée à lutter contre les inégalités en matière de santé dans sa récente déclaration sur le racisme. L'objectif de ce projet était d'élaborer des recommandations pour lutter contre le racisme et le colonialisme en médecine d'urgence. MéTHODES: Les auteurs, en collaboration avec un groupe de travail de 40 membres, ont effectué une recherche documentaire, tenu une consultation communautaire, sollicité les commentaires d'experts en médecine, en enseignement et en services communautaires, mené une enquête nationale auprès des médecins d'urgence et ont présenté des ébauches de recommandations lors du Symposium académique de l'ACMU 2021 sur l'Équité, la Diversité et l'inclusion pour une discussion animée en direct avec un sondage après la séance. RéSULTATS: Seize recommandations ont été formulées dans les domaines des soins aux patients, de l'engagement de l'hôpital et du service en matière d'Équité, de Diversité et d'Inclusion, de l'avancement des médecins, du développement professionnel et de l'éducation médicale. CONCLUSION: Les médecins urgentistes sont particulièrement bien placés pour promouvoir l'équité à chaque rencontre avec les patients, les pairs et les apprenants. Les 16 recommandations présentées ici sont des mesures pratiques pour contrer le racisme et le colonialisme au quotidien dans la médecine d'urgence.

Utilization of CT angiography of the head and neck in the era of endovascular therapy for acute ischemic stroke: a retrospective study.

PURPOSE: To describe the impact of a new institutional Code Stroke protocol on ordering volume of head and neck CT angiographies (CTA), and to determine the number and proportion of these studies that resulted in an endovascular or surgical intervention. METHODS: Clinical and administrative data was collected on all head and neck CTAs ordered within the ED at two high-volume community hospitals and an affiliated urgent care centre during the 6-year period between January 1, 2014, and December 31, 2019. Of those patients who underwent CTA, we identified those who were then transferred to a regional stroke centre for consideration of EVT and those who underwent carotid endarterectomy or stenting within 14 days. RESULTS: A total of 4719 CTAs were ordered during the 6-year period. There was nearly a tenfold rise in the yearly number of CTAs ordered per 10,000 ED visits, from 5.3 (in 2014) to 53.1 (in 2019). A total of 164 patients who underwent CTAs (3.5%) were ultimately transferred to a regional tertiary care centre, of whom 43 (0.9%) were transferred to a regional stroke centre for consideration of EVT. A total of 61 (1.3%) patients underwent a carotid intervention within 14 days. CONCLUSION: Little is known of the impacts on healthcare resources that have resulted from the system-wide changes made necessary by the widespread adoption of EVT. Our study shows that at our site, these system changes have resulted in large increases in CTA utilization with very small numbers of patients ultimately undergoing EVT or carotid intervention.

Utilization of serum D-dimer assays prior to computed tomography pulmonary angiography scans in the diagnosis of pulmonary embolism among emergency department physicians: a retrospective observational study.

BACKGROUND: A variety of evidence-based algorithms and decision rules using D-Dimer testing have been proposed as instruments to allow physicians to safely rule out a pulmonary embolism (PE) in low-risk patients. OBJECTIVE: To describe the prevalence of D-Dimer utilization among emergency department (ED) physicians and its impact on positive yields and utilization rates of Computed Tomography Pulmonary Angiography (CTPA). METHODS: Data was collected on all CTPA studies ordered by ED physicians at three sites during a 2-year period. Using a chi-square test, we compared the diagnostic yield for those patients who had a D-Dimer prior to their CTPA and those who did not. Secondary analysis was done to examine the impact of D-Dimer testing prior to CTPA on individual physician diagnostic yield or utilization rate. RESULTS: A total of 2811 CTPAs were included in the analysis. Of these, 964 CTPAs (34.3%) were ordered without a D-Dimer, and 343 (18.7%) underwent a CTPA despite a negative D-Dimer. Those CTPAs preceded by a D-Dimer showed no significant difference in positive yields when compared to those ordered without a D-Dimer (9.9% versus 11.3%, p = 0.26). At the individual physician level, no statistically significant relationship was found between D-Dimer utilization and CTPA utilization rate or diagnostic yield. CONCLUSION: This study provides evidence of suboptimal adherence to guidelines in terms of D-Dimer screening prior to CTPA, and forgoing CTPAs in patients with negative D-Dimers. However, the lack of a positive impact of D-Dimer testing on either CTPA diagnostic yield or utilization rate is indicative of issues relating to the high false-positive rates associated with D-Dimer screening.

Variability in practice patterns among emergency physicians in the evaluation of patients with a suspected diagnosis of pulmonary embolism.

PURPOSE: To describe the inter-physician variability in the utilisation rate and diagnostic yield of computed tomography pulmonary angiography (CTPA) among a group of emergency department (ED) physicians working in a similar clinical environment. METHODS: We collected data on all CTPA studies ordered by ED physicians at three affiliated sites during a 2-year period between January 1, 2016, and December 31, 2017. For each physician, we calculated individual CTPA utilisation rate (total number of CTPAs ordered per 1000 ED visits) and diagnostic yield (percentage of CTPAs that were positive for PE). Additional analysis was carried out in order to identify the highest orderers of CTPA and their diagnostic yield. RESULTS: Seventy-seven ED physicians who collectively ordered a total of 2788 CTPAs were included in the study. Utilisation rates ranged from 1.1 to 22.2 CTPA per 1000 ED visits (median: 5.2 CTPA/1000 ED visits; 25%ile: 3.6 CTPA/1000 ED visits; 75%ile: 7.9 CTPA/1000 ED visits) and the CTPA diagnostic yields ranged from 0% to 33% (median: 9.1%; 25%ile: 5.2%; 75%ile: 16.1%). Those physicians in the lower quartile for ordering rate had a higher mean diagnostic yield when compared to the higher quartiles. CONCLUSION: The findings of this study demonstrate variability in CTPA ordering patterns and diagnostic yields among physicians working within the same clinical environment. There is some suggestion that those physicians who order disproportionately higher numbers of CTPAs have lower diagnostic yields.

Time of Transfer of Admitted Patients from the ED: A Contributor to ED Boarding in High-Volume Community Hospitals.

The twin challenges of bed boarding and "hallway medicine" have emerged in recent years as key healthcare issues. Many hospitals, challenged with increasing demand and limited resources, have tried to find efficiencies within their operations. One such strategy is that of early morning discharges and expedited bed turnaround times. We conducted a retrospective study within three high-volume hospitals in the Greater Toronto Area looking at discharge times of in-patients and transfer times of admitted, Emergency Department (ED)-boarded patients. We discovered a consistent pattern of late-in-the-day discharges, and even later-in-the-day transfers of boarded ED patients, indicating that this may be a potential source of increased efficiency for overburdened hospitals.

Emergency department boarding: a descriptive analysis and measurement of impact on outcomes.

OBJECTIVES: Delays in transfer of admitted patients boarded in the emergency department (ED) to an inpatient bed is a major driver of ED overcrowding. We sought to identify explanatory factors behind ED boarding as well as the impact of boarding on total inpatient length of stay (IP LOS) and inpatient mortality. METHODS: We conducted a retrospective single-centre observational study during the period between January 1 and December 31, 2015 at a very high volume community hospital. All patients admitted from the ED to Medicine, Pediatrics, Surgery, and Critical Care were identified. The mean ED LOS and boarding time as well as patient-specific and institutional factors that were independently associated with prolonged ED LOS (≥24 hours) and prolonged boarding time (≥12 hours) were identified. Mean inpatient length of stay (IP LOS) and the odds of inpatient mortality were calculated for those patients with prolonged ED wait times. RESULTS: There were 13,872 unique admissions during the study period. Patients admitted to the Medicine service exhibited significantly higher ED wait times than other services. Within Medicine patients, there was a statistically significant greater odds of prolonged ED wait times for patients who were older, had a greater comorbidity burden, and required more specialized inpatient care. Medicine patients with prolonged boarding times also experienced a mean of 0.9 days longer IP LOS even after adjusting for confounders. CONCLUSION: Within our cohort, older, sicker patients and those patients requiring more resource-intensive inpatient care had the longest ED wait times. These prolonged wait times are associated with significantly increased IP LOS.
