The objective of this study was to compare the emergency department (ED) management and rate of admission of acute decompensated heart failure (ADHF) between two hospitals in Canada and the United States and to compare the outcomes of these patients.

This was a health records review of adults presenting with ADHF to two EDs in Canada and the United States between January 1 and April 30, 2010. Outcome measures were admission to the hospital, myocardial infarction (MI), and death or relapse rates to the ED. Data were analysed using descriptive, univariate and multivariate analyses.

In total, 394 cases were reviewed and 73 were excluded. Comparing 156 Canadian to 165 U.S. patients, respectively, mean age was 76.0 and 75.8 years; male sex was 54.5% and 52.1%. Canadian and U.S. ED treatments were noninvasive ventilation 7.7% v. 12.8% (p=0.13); IV diuretics 77.6% v. 36.0% (p<0.001); IV nitrates 4.5% v. 6.7% (p=0.39). There were significant differences in rate of admission (50.6% v. 95.2%, p<0.001) and length of stay in ED (6.7 v. 3.0 hours, p<0.001). Proportion of Canadian and U.S. patients who died within 30 days of the ED visit was 5.1% v. 9.7% (p=0.12); relapsed to the ED within 30 days was 20.8% v. 17.5% (p=0.5); and had MI within 30 days was 2.0% v. 1.9% (p=1.0).

The U.S. and Canadian centres saw ADHF patients with similar characteristics. Although the U.S. site had almost double the admission rate, the outcomes were similar between the sites, which question the necessity of routine admission for patients with ADHF.

Hip fractures are a common source of acute pain amongst the frail elderly. One potential technique to adequately manage pain in this population is the femoral nerve block. The objective of this systematic review was to provide updated evidence for the use of femoral nerve blocks as a pain management technique for older hip fracture patients in the emergency department (ED).

Searches of Medline, EMBASE, and the Cochrane Central Register of Controlled Trials were conducted between December 2010 and May 2014. The reference list of a previous systematic review was also searched.

We included randomized control trials examining the use of femoral nerve blocks in the ED among older adults (65 years of age or older) with acute hip fracture.

Among 93 citations reviewed, seven trials were included. Four studies employed a single femoral nerve block, while three studies employed continuous (catheter-placed) femoral blocks. All but one of the studies were found to have a high risk of bias.

All studies reported reductions in pain intensity with femoral nerve blocks. All but one study reported decreased rescue analgesia requirements. There were no adverse effects found to be associated with the femoral block procedure; rather, two studies found a decreased risk of adverse events such as respiratory and cardiac complications.

Femoral nerve blocks appear to have benefits both in terms of decreasing the pain experienced by older patients, as well as limiting the amount of systemic opioids administered to this population.

Evidence exists that analgesics are underutilized, delayed, and insufficiently dosed for emergency department (ED) patients with acute abdominal pain. For physicians practicing in a Canadian paediatric ED setting, we (1) explored theoretical practice variation in the provision of analgesia to children with acute abdominal pain; (2) identified reasons for withholding analgesia; and (3) evaluated the relationship between providing analgesia and surgical consultation.

Physician members of Paediatric Emergency Research Canada (PERC) were prospectively surveyed and presented with three scenarios of undifferentiated acute abdominal pain to assess management. A modified Dillman’s Tailored Design method was used to distribute the survey from June to July 2014.

Overall response rate was 74.5% (149/200); 51.7% of respondents were female and mean age was 44 (SD 8.4) years. The reported rates of providing analgesia for case scenarios representative of renal colic, appendicitis, and intussusception, were 100%, 92.1%, and 83.4%, respectively, while rates of providing intravenous opioids were 85.2%, 58.6%, and 12.4%, respectively. In all 60 responses where the respondent indicated they would obtain a surgical consultation, analgesia would be provided. In the 35 responses where analgesia would be withheld, 21 (60%) believed pain was not severe enough, while 5 (14.3%) indicated it would obscure a surgical condition.

Pediatric emergency physicians self-reported rates of providing analgesia for acute abdominal pain scenarios were higher than previously reported, and appeared unrelated to request for surgical consultation. However, an unwillingness to provide opioid analgesia, belief that analgesia can obscure a surgical condition, and failure to take self-reported pain at face value remain, suggesting that the need exists for further knowledge translation efforts.

Emergency physicians who work in academic settings enjoy an expanding number of roles beyond that of the skilled clinician. Faculty development (FD) encompasses the broad range of activities that institutions use to renew skill-sets and assist faculty members in these multiple roles. This study seeks to define the current FD needs and interests of Canadian academic emergency physicians (AEPs).

An online survey was administered to 943 AEPs in eight centers across Canada to determine their current FD activities, provide a detailed understanding of their FD needs and interests, elucidate the perceived barriers to and motivation for engaging in FD, and identify preferred methods of delivery for FD activities.

This national, cross-sectional survey was completed by 336 respondents. It shows that need for FD is universally high, particularly in traditional domains of scholarship, leadership and education (79%, 80%, 87% overall interest, respectively). However, the study also suggests that there is increasing need for FD in areas where current participation is lowest, namely research and social accountability (12% and 13% more interest, respectively). Senior and junior faculty evince equivalent overall FD interest (p>0.05), whereas female AEPs expressed greater overall FD needs in leadership (1.82 vs 1.44 activities, p=0.003) than males. Continued participation in FD activities is best promoted by offering relevant topics, at convenient times and locations.

This study reports the first comprehensive national FD needs assessment of Canadian academic emergency physicians.

L’objectif de cette étude rétrospective était d’identifier les facteurs associés aux décomptes quotidiens de départs avant prise en charge médicale (DAPCM) dans les deux salles d’urgence du Centre hospitalier universitaire de Sherbrooke, Fleurimont (HF) et Hôtel-Dieu (HD).

Des données cliniques et démographiques anonymisées, ainsi que des données hospitalières, ont été extraites de la banque de données du Centre Informatisé de Recherche Évaluative en Services et Soins de Santé pour la période du 1er avril 2011 au 30 juin 2012. Les variables étant corrélées au nombre de DAPCM par jour par site lors des analyses univariées ont été retenues pour l’analyse de régression linéaire multivariée.

Les analyses de régression multivariées démontrent que le nombre de DAPCM par jour diminue pour les deux sites lorsque la durée moyenne de séjour des patients non hospitalisés à l’urgence diminue (HF:b=1,17, p<0,001; HD:b=1,41, p<0,001) et lorsqu’un médecin dédié aux patients ambulatoires est présent (HF:b=-4,35, p<0,001; HD:b=-5,48, p<0,001). De plus, des facteurs reliés à l’achalandage des salles d’urgence et la raison primaire de consultation ont également eu un effet sur le nombre de DAPCM par jour.

Des efforts devraient être faits afin de diminuer la durée moyenne de séjour des patients non hospitalisés à l’urgence et d’assurer la présence d’un médecin dédié aux patients ambulatoires pour diminuer le nombre de DAPCM.

To develop a simulation-based curriculum for residents to learn ultrasound-guided (USG) central venous catheter (CVC) insertion, and to study the volume and type of practice that leads to technical proficiency.

Ten post-graduate year two residents from the Departments of Emergency Medicine and Anesthesiology completed four training sessions of two hours each, at two week intervals, where they engaged in a structured program of deliberate practice of the fundamental skills of USG CVC insertion on a simulator. Progress during training was monitored using regular hand motion analysis (HMA) and performance benchmarks were determined by HMA of local experts. Blinded assessment of video recordings was done at the end of training to assess technical competence using a global rating scale.

None of the residents met any of the expert benchmarks at baseline. Over the course of training, the HMA metrics of the residents revealed steady and significant improvement in technical proficiency. By the end of the fourth session six of 10 residents had faster procedure times than the mean expert benchmark, and nine of 10 residents had more efficient left and right hand motions than the mean expert benchmarks. Nine residents achieved mean GRS scores rating them competent to perform independently.

We successfully developed a simulation-based curriculum for residents learning the skills of USG CVC insertion. Our results suggest that engaging residents in three to four distributed sessions of deliberate practice of the fundamental skills of USG CVC insertion leads to steady and marked improvement in technical proficiency with individuals approaching or exceeding expert level benchmarks.

A panel of emergency medicine (EM) leaders endeavoured to define the key elements of leadership and its models, as well as to formulate consensus recommendations to build and strengthen academic leadership in the Canadian EM community in the areas of mentorship, education, and resources.

The expert panel comprised EM leaders from across Canada and met regularly by teleconference over the course of 9 months. From the breadth of backgrounds and experience, as well as a literature review and the development of a leadership video series, broad themes for recommendations around the building and strengthening of EM leadership were presented at the CAEP 2015 Academic Symposium held in Edmonton, Alberta. Feedback from the attendees (about 80 emergency physicians interested in leadership) was sought. Subsequently, draft recommendations were developed by the panel through attendee feedback, further review of the leadership video series, and expert opinion. The recommendations were distributed to the CAEP Academic Section for further feedback and updated by consensus of the expert panel.

The methods informed the panel who framed recommendations around four themes: 1) leadership preparation and training, 2) self-reflection/emotional intelligence, 3) academic leadership skills, and 4) gender balance in academic EM leadership. The recommendations aimed to support and nurture the next generation of academic EM leaders in Canada and included leadership mentors, availability of formal educational courses/programs in leadership, self-directed education of aspiring leaders, creation of a Canadian subgroup with the AACEM/SAEM Chair Development Program, and gender balance in leadership roles.

These recommendations serve as a roadmap for all EM leaders (and aspiring leaders) to build on their success, inspire their colleagues, and foster the next generation of Canadian EM academic leaders.

To determine the effect of triage nurse initiated radiographs using the Ottawa Ankle Rules (OAR) on emergency department (ED) throughput. We hypothesized OAR use would reduce median ED length of stay (LOS) by 25 minutes or more.

A randomized controlled trial was conducted at a tertiary centre ED with an annual census of over 90,000 patients. Adult patients presenting within 10 days of isolated blunt ankle trauma were eligible. Participants were randomly assigned to standard triage or OAR application by 15 explicitly trained triage nurses. Our primary outcome was ED LOS. Secondary outcomes included triage nurses' and patients’ satisfaction. A power calculation indicated 142 patients were required. The Mann-Whitney U test was used to compare the medians between the two groups.

Of 176 patients with blunt ankle injury screened, 146 were enrolled (83.0%); baseline characteristics in the two groups were similar. The median/mean ED LOS in the control and OAR groups were 128/143 minutes and 108/115 minutes respectively (median difference 20 minutes; p=0.003). Agreement in OAR use between emergency physicians and nurses was moderate (kappa 0.46/0.77 for foot/ankle rule components), and satisfaction of both nurses and participants was high.

Triage nurse initiated radiography using OAR leads to a statistically significant decrease of 20 minutes in the median ED LOS at a tertiary care centre. The overall impact of implementing such a process is likely site-specific, and the decision to do so should involve consideration of the local context.

Bystander cardiopulmonary resuscitation (CPR) improves the likelihood of survival from out-of-hospital cardiac arrest (OHCA), yet it is performed in only 30% of cases. The 2010 guidelines promote chest-compression-only bystander CPR—a change intended to increase willingness to provide CPR.

1) To determine whether the Canadian general public is more willing to perform chest-compression-only CPR compared to traditional CPR; 2) to characterize public knowledge of OHCA; and 3) to identify barriers and facilitators to bystander CPR.

A 32-item survey assessing resuscitation knowledge, and willingness to provide CPR were disseminated in five Canadian regions. Descriptive statistics were used to characterize response distribution. Logistic regression analysis was applied to assess shifts in intention to provide CPR.

A total of 428 completed surveys were analysed. When presented with a scenario of being a bystander in an OHCA, a greater proportion of respondents were willing to provide chest-compression-only CPR compared to traditional CPR for all victims (61.5% v. 39.7%, p<0.001), when the victim was a stranger (55.1% v. 38.8%, p<0.001), or when the victim was an unkempt individual (47.9% v. 28.5%, p<0.001). When asked to describe an OHCA, 41.4% said the heart stopped beating, and 20.8% said it was a heart attack. Identified barriers and facilitators included fear of litigation and lack of skill confidence.

This study identified gaps in knowledge, which may impair the ability of bystanders to act in OHCA. Most respondents expressed greater willingness to provide chest-compression-only CPR, but this was mediated by victim characteristics, skill confidence, and recognition of a cardiac arrest.

1) To evaluate whether transient ischemic attack (TIA) management in emergency departments (EDs) of the Nova Scotia Capital District Health Authority followed Canadian Best Practice Recommendations, and 2) to assess the impact of being followed up in a dedicated outpatient neurovascular clinic.

Retrospective chart review of all patients discharged from EDs in our district from January 1, 2011 to December 31, 2012 with a diagnosis of TIA. Cox proportional hazards models, Kaplan-Meier survival curve, and propensity matched analyses were used to evaluate 90-day mortality and readmission.

Of the 686 patients seen in the ED for TIA, 88.3% received computed tomography (CT) scanning, 86.3% received an electrocardiogram (ECG), 35% received vascular imaging within 24 hours of triage, 36% were seen in a neurovascular clinic, and 4.2% experienced stroke, myocardial infarction, or vascular death within 90 days. Rates of antithrombotic use were increased in patients seen in a neurovascular clinic compared to those who were not (94% v. 86.3%, p<0.0001). After adjustment for age, sex, vascular disease risk factors, and stroke symptoms, the risk of readmission for stroke, myocardial infarction, or vascular death was lower for those seen in a neurovascular clinic compared to those who were not (adjusted hazard ratio 0.28; 95% confidence interval 0.08–0.99, p=0.048).

The majority of patients in our study were treated with antithrombotic agents in the ED and investigated with CT and ECG within 24 hours; however, vascular imaging and neurovascular clinic follow-up were underutilized. For those with neurovascular clinic follow-up, there was an association with reduced risk of subsequent stroke, myocardial infarction, or vascular death.

We examined the effect of a full bladder on proportions of diagnostic ultrasound (US) studies in children with suspected appendicitis. We also examined the effect of a full bladder on proportions of fully visualized ovaries on US in children with suspected appendicitis.

We conducted a retrospective health record review of children aged 2-17 years presenting to a tertiary pediatric emergency department (ED) with suspected appendicitis who had an ultrasound performed. We compared proportions of diagnostic US studies in children with full and sub-optimally filled bladders. We also compared proportions of ovarian visualization in females with full and sub-optimally filled bladders.

678 children were included in our final analysis. The proportion of diagnostic US studies did not vary significantly between groups with a full (132/283, 47%, 95% confidence interval [CI] 38%-56%) or sub-optimally filled bladder (205/395, 52%, 95% CI 47%-57%)(p=0.17). Rates of ovarian visualization were higher in females with a full bladder (196/205, 96%, 95% CI 93%-99%) compared to those with a sub-optimally filled bladder (180/223, 81%, 95% CI 76%-86%) (p<0.01).

Administrators and clinical decision makers should consider removing routine bladder filling practice from current pediatric appendicitis protocols in males and in pre-pubertal females where ovarian pathology is not suspected. Selective bladder filling prior to US should be performed in females when ovarian pathology is suspected.

We sought to compare two ultrasound simulation interventions used during critical care simulation. The primary outcome was trainee and instructor preference for either intervention. Secondary outcomes included the identification of strengths and weaknesses of each intervention as well as overall merits of ultrasound simulation during high-fidelity, critical care simulation. The populations of interest included emergency medicine trainees and physicians.

This was a randomized crossover study with two ultrasound simulation interventions. 25 trainees and eight emergency physician instructors participated in critical-care simulation sessions. Instructors were involved in session debriefing and feedback. Pre- and post-intervention responses were analyzed for statistically significant differences using t test analyses. Qualitative data underwent thematic analysis and triangulation.

Both trainees and instructors deemed ultrasound simulation valuable by allowing trainees to demonstrate knowledge of indications, correct image interpretation, and clinical integration (p<0.05). Trainees described increased motivation to develop and use ultrasound skills. The edus2 was the preferred intervention, as it enabled functional fidelity and the integration of ultrasound into resuscitation choreography. Instructors preferred the edus2, as it facilitated better assessment of trainees’ skills, thus influencing feedback.

These findings support the use of ultrasound simulation during critical care simulations. The increased functional fidelity associated with edus2 suggests that it is the preferred intervention. Further study of the impact on clinical performance is warranted.

To describe the current state of academic emergency medicine (EM) funding in Canada and develop recommendations to grow and establish sustainable funding.

A panel of eight leaders from different EM academic units was assembled. Using mixed methods (including a literature review, sharing of professional experiences, a survey of current EM academic heads, and data previously collected from an environmental scan), 10 recommendations were drafted and presented at an academic symposium. Attendee feedback was incorporated, and the second set of draft recommendations was further distributed to the Canadian Association Emergency Physicians (CAEP) Academic Section for additional comments before being finalized.

Recommendations were developed around the funding challenges identified and solutions developed by academic EM university-based units across Canada. A strategic plan was seen as integral to achieving strong funding of an EM unit, especially when it aligned with departmental and institutional priorities. A business plan, although occasionally overlooked, was deemed an important component for planning and sustaining the academic mission. A number of recommendations surrounding philanthropy consisted of creating partnerships with existing foundations and engaging multiple stakeholders and communities. Synergy between academic and clinical EM departments was also viewed as an opportunity to ensure integration of common missions. Education and networking for current and future leaders were also viewed as invaluable to ensure that opportunities are optimized through strong leadership development and shared experiences to further the EM academic missions across the country.

These recommendations were designed to improve the financial circumstances for many Canadian EM units. There is a considerable wealth of resources that can contribute to financial stability for an academic unit, and an annual networking meeting and continuing education on these issues will facilitate more rapid implementation of these recommendations.

Five percent of transient ischemic attack (TIA) patients have a subsequent stroke within 7 days. The Canadian TIA Score uses clinical findings to calculate the subsequent stroke risk within 7 days. Our objectives were to assess 1) anticipated use; 2) component face validity; 3) risk strata for stroke within 7 days; and 4) actions required, for a given risk for subsequent stroke.

After a rigorous development process, a survey questionnaire was administered to a random sample of 300 emergency physicians selected from those registered in a national medical directory. The surveys were distributed using a modified Dillman technique.

From a total of 271 eligible surveys, we received 131 (48.3%) completed surveys; 96.2% of emergency physicians would use a validated Canadian TIA Score; 8 of 13 components comprising the Canadian TIA Score were rated as Very Important or Important by survey respondents. Risk categories for subsequent stroke were defined as minimal-risk: <1%; low-risk: 1%–4.9%; high-risk 5%–10%; critical-risk: > 10% risk of subsequent stroke within 7 days.

A validated Canadian TIA Score will likely be used by emergency physicians. Most components of the TIA Score have high face validity. Risk strata are definable, which may allow physicians to determine immediate actions, based on subsequent stroke risk, in the emergency department.

Patients with venous thromboembolism (VTE) (deep vein thrombosis [DVT] and pulmonary embolism [PE]) are commonly treated as outpatients. Traditionally, patients are anticoagulated with low-molecular-weight heparin (LMWH) and warfarin, resulting in return visits to the ED. The direct oral anticoagulant (DOAC) medications do not require therapeutic monitoring or repeat visits; however, they are more expensive. This study compared health costs, from the hospital and patient perspectives, between traditional versus DOAC therapy.

A chart review of VTE cases at two tertiary, urban hospitals from January 1, 2010 to December 31, 2012 was performed to capture historical practice in VTE management, using LMWH/warfarin. This historical data were compared against data derived from clinical trials, where a DOAC was used. Cost minimization analyses comparing the two modes of anticoagulation were completed from hospital and patient perspectives.

Of the 207 cases in the cohort, only 130 (63.2%) were therapeutically anticoagulated (international normalized ratio 2.0–3.0) at emergency department (ED) discharge; patients returned for a mean of 7.18 (range: 1–21) visits. Twenty-one (10%) were admitted to the hospital; 4 (1.9%) were related to VTE or anticoagulation complications. From a hospital perspective, a DOAC (in this case, rivaroxaban) had a total cost avoidance of $1,488.04 per VTE event, per patient. From a patient perspective, it would cost an additional $204.10 to $349.04 over 6 months, assuming no reimbursement.

VTE management in the ED has opportunities for improvement. A DOAC is a viable and cost-effective strategy for VTE treatment from a hospital perspective and, depending on patient characteristics and values, may also be an appropriate and cost-effective option from a patient perspective.

1) To identify the strengths and challenges of governance structures in academic emergency medicine (EM), and 2) to make recommendations on principles and approaches that may guide improvements.

Over the course of 9 months, eight established EM leaders met by teleconference, reviewed the literature, and discussed their findings and experiences to arrive at recommendations on governance in academic units of EM. The results and recommendations were presented at the annual Canadian Association of Emergency Physicians (CAEP) Academic Symposium, where attendees provided feedback. The updated recommendations were subsequently distributed to the CAEP Academic Section for further input, and the final recommendations were decided by consensus.

The panel identified four governance areas of interest: 1) the elements of governance; 2) the relationships between emergency physicians and academic units of EM, and between the academic units of EM and faculty of medicine; 3) current status of governance in Canadian academic units of EM; and 4) essential elements of good governance. Six recommendations were developed around three themes, including 1) the importance of good governance; 2) the purposes of an academic unit of EM; and 3) essential elements for better governance for academic units of EM. Recommendations included identifying the importance of good governance, recognizing the need to adapt to the different models depending on the local environment; seeking full departmental status, provided it is mutually beneficial to EM and the faculty of medicine (and health authority); using a consultation service to learn from the experience of other academic units of EM; and establishing an annual forum for EM leaders.

Although governance of academic EM is complex, there are ways to iteratively improve the mission of academic units of EM: providing exceptional patient care through research and education. Although there is no one-size-fits-all guide, there are practical recommended steps for academic units of EM to consider.

We explored caregiver perspectives on their children’s pain management in both a pediatric (PED) and general emergency department (GED). Study objectives were to: (1) measure caregiver estimates of children’s pain scores and treatment; (2) determine caregiver level of satisfaction; and (3) determine factors associated with caregiver satisfaction.

This prospective survey examined a convenience sample of 97 caregivers (n=51 PED, n=46 GED) with children aged <17 years. A paper-based survey was distributed by research assistants, from 2009–2011.

Most caregivers were female (n=77, 79%) and were the child’s mother (n=69, 71%). Children were treated primarily for musculoskeletal pain (n=41, 42%), headache (n=16, 16%) and abdominal pain (n=7, 7%). Using a 100 mm Visual Analog Scale, the maximum mean reported pain score was 75 mm (95% CI: 70–80) and mean score at discharge was 39 mm (95% CI: 32–46). Ninety percent of caregiver respondents were satisfied (80/89, 90%); three (3/50, 6%) were dissatisfied in the PED and six (6/39, 15%) in the GED. Caregivers who rated their child’s pain at ED discharge as severe were less likely to be satisfied than those who rated their child’s pain as mild or moderate (p=0.034).

Despite continued pain upon discharge, most caregivers report being satisfied with their child’s pain management. Caregiver satisfaction is likely multifactorial, and physicians should be careful not to interpret satisfaction as equivalent to adequate provision of analgesia. The relationship between satisfaction and pain merits further exploration.

The purpose of this study was to evaluate the cost-effectiveness of physician-nurse supplementary triage assistance team (MDRNSTAT) from a hospital and patient perspective.

This was a cost-effectiveness evaluation of a cluster randomized control trial comparing the MDRNSTAT with nurse-only triage in the emergency department (ED) between the hours of 0800 and 1500. Cost was MDRNSTAT salary. Revenue was from Ontario’s Pay-for-Results and patient volume-case mix payment programs. The incremental cost-effectiveness ratio was based on MDRNSTAT cost and three consequence assessments: 1) per additional patient-seen; 2) per physician initial assessment (PIA) hour saved; and 3) per ED length of stay (EDLOS) hour saved. Patient opportunity cost was determined. Patient satisfaction was quantified by a cost-benefit ratio. A sensitivity analysis extrapolating MDRNSTAT to different working hours, salary, and willingness-to-pay data was performed.

The added cost of the MDRNSTAT was $3,597.27 [$1,729.47 to ∞] per additional patient-seen, $75.37 [$67.99 to $105.30] per PIA hour saved, and $112.99 [$74.68 to $251.43] per EDLOS hour saved. From the hospital perspective, the cost-benefit ratio was 38.6 [19.0 to ∞] and net present value of –$447,996 [–$435,646 to –$459,900]. For patients, the cost-benefit ratio for satisfaction was 2.8 [2.3 to 4.6]. If MDRNSTAT performance were consistently implemented from noon to midnight, it would be more cost-effective.

The MDRNSTAT is not a cost-effective daytime strategy but appears to be more feasible during time periods with higher patient volume, such as late morning to evening.

This retrospective cohort study compared rates of emergency department (ED) visits after a diagnosis of chronic obstructive pulmonary disease (COPD) in the three Aboriginal groups (Registered First Nations, Métis and Inuit) relative to a non-Aboriginal cohort.

We linked eight years of administrative health data from Alberta and calculated age- and sex-standardized ED visit rates in cohorts of Aboriginal and non-Aboriginal individuals diagnosed with COPD. Rate ratios (RR) with 95% confidence intervals (CIs) were calculated in a Poisson regression model that adjusted for important sociodemographic factors and comorbidities. Differences in ED length of stay (LOS) and disposition status were also evaluated.

A total of 2,274 Aboriginal people and 1,611 non-Aboriginals were newly diagnosed with COPD during the study period. After adjusting for important sociodemographic and clinical factors, the rate of all-cause ED visits in all Aboriginal people (RR=1.72, 95% CI: 1.67, 1.77), particularly among Registered First Nations people (RR=2.02; 95% CI: 1.97, 2.08) and Inuit (RR=1.28; 95% CI: 1.22, 1.35), were significantly higher than that in non-Aboriginals, while ED visit rates were significantly lower in the Métis (RR=0.94; 95% CI: 0.90, 0.98). The ED LOS in all Aboriginal groups were significantly lower than that of the non-Aboriginal group.

Aboriginal people with COPD use almost twice the amount of ED services compared to their non-Aboriginal counterparts. There are also important variations in patterns of ED services use among different Aboriginal groups with COPD in Alberta.

Computerized provider order entry (CPOE) has been established as a method to improve patient safety by avoiding medication errors; however, its effect on emergency department (ED) flow remains undefined. We examined the impact of CPOE implementation on three measures of ED throughput: wait time (WT), length of stay (LOS), and the proportion of patients that left without being seen (LWBS).

We conducted a retrospective cohort study of all ED patients of 18 years and older presenting to London Health Sciences Centre during July and August 2013 and 2014, before and after implementation of a CPOE system. The three primary variables were compared between time periods. Subgroup analyses were also conducted within each Canadian Triage and Acuity Scale (CTAS) level (1–5) individually, as well as for admitted patients only.

A significant increase in WT of 5 minutes (p=0.036) and LOS of 10 minutes (p=0.001), and an increase in LWBS from 7.2% to 8.1% (p=0.002) was seen after CPOE implementation. Admitted patients’ LOS increased by 63 minutes (p<0.001), the WT of CTAS 3 and 5 patients increased by 6 minutes (p=0.001) and 39 minutes (p=0.005), and LWBS proportion increased significantly for CTAS 3–5 patients, from 24.3% to 42.0% (p<0.001) for CTAS 5 patients specifically.

CPOE implementation detrimentally impacted all patient flow throughput measures that we examined. The most striking clinically relevant result was the increase in LOS of 63 minutes for admitted patients. This raises the question as to whether the potential detrimental effects to patient safety of CPOE implementation outweigh its benefits.
