Acutely painful osteoporotic vertebral compression fractures are associated with hospitalization and mortality in older adults. Calcitonin may be an alternative to opioid or nonopioid analgesia for treating acute compression fracture pain in emergency and primary care settings. This review summarizes pain, function, and adverse events associated with calcitonin.

We searched MEDLINE, EMBASE, The Cochrane Library, clinical trials registries, and reference lists of included studies. Eligible studies evaluated the effect of synthetic calcitonins (salmon, eel, and human) on pain scores in adults ≥60 years old with a recent atraumatic compression fracture. Two reviewers screened studies, extracted data, and allocated bias in duplicate. A random effects meta-analysis evaluated standard mean difference (SMD) and heterogeneity (I2).

Of 1,198 articles screened, 11 were included (9 in the meta-analysis). Treatment lasted from 14 days to 6 months. Pain was lower in the salmon calcitonin group (100–200 IU IM or NAS, daily) than the control group with high certainty of evidence at week 1 (SMD, -1.54; 95% confidence interval [CI], -2.02 – -1.06; I2 = 52%), representing a number needed to treat of two. The analgesic efficacy of salmon calcitonin at 4 weeks was unclear due to substantial heterogeneity. There was low certainty evidence that calcitonin did not increase the overall risk of adverse events, including nausea and vomiting (risk ratio, 2.10; 95% CI, 0.87–5.08; I2 = 47%).

Calcitonin is beneficial and appears safe for treating acute pain associated with compression fractures. Further studies may improve the certainty of evidence.

The aims of this study were to describe emergency department (ED) utilization by people in provincial prison and on release, and to compare with ED utilization for the general population.

We linked correctional and health administrative data for people released from provincial prison in Ontario in 2010. We matched each person by age and sex with four people in the general population. We compared ED utilization rates using generalized estimating equations, by sex and for high urgency and ambulatory care sensitive conditions.

People who experienced imprisonment (N = 48,861) had higher ED utilization rates compared with the general population (N = 195,444), with rate ratios of 3.2 (95% CI 3.0–4.4) for men and 6.5 (95% CI 5.6–7.5) for women in prison and a range of rate ratios between 3.1 and 7.7 for men and 4.2 and 8.8 for women over the 2 years after release. Most ED visits were high urgency, and between 1.0% and 5.1% of visits were for ambulatory care sensitive conditions. ED utilization rates increased on release from prison.

People experiencing imprisonment in Ontario have higher ED utilization compared with matched people in the general population, primarily for urgent issues, and particularly in women and in the week after release. Providing high-quality ED care and implementing prison- and ED-based interventions could improve health for this population and prevent the need for ED use.

HealthLine is Saskatchewan's provincial 24-hour health information and support telephone line. A proportion of HealthLine's callers are referred to the emergency department (ED) for further assessment. The purpose of this study was to gain insight into the appropriateness of these referrals and assess whether they increased the burden on an already strained ED system.

A list of callers referred from HealthLine to Saskatoon EDs from January 1, 2014, to March 31, 2014 was obtained. This list was cross-referenced with Saskatoon Health Region registration data to determine which of those callers had been registered in one of the three Saskatoon EDs within 48 hours of the original call.

During the 90-day time period in question, 707/3,938 (17.9%) of callers were referred by HealthLine to the ED. Out of those referred, 601 were identifiable and 358 attended the ED. Hospital charts were pulled for full data extraction and analysis of the 276 who met inclusion criteria. Of those who presented to the ED and met inclusion criteria, 60% had investigations performed while 66% received some form of treatment. The overall admission rate for the patient population studied was 12.0% v. 16% for non-referred patients. Referred pediatric patients had fewer investigations and treatments with a lower admission rate compared with the adult patients.

The Saskatchewan HealthLine is doing an effective job at directing callers both to and away from EDs in Saskatoon and not overburdening our local EDs with unnecessary referrals.

Simulation plays an integral role in the Canadian healthcare system with applications in quality improvement, systems development, and medical education. High-quality, simulation-based research will ensure its effective use. This study sought to summarize simulation-based research activity and its facilitators and barriers, as well as establish priorities for simulation-based research in Canadian emergency medicine (EM).

Simulation-leads from Canadian departments or divisions of EM associated with a general FRCP-EM training program surveyed and documented active EM simulation-based research at their institutions and identified the perceived facilitators and barriers. Priorities for simulation-based research were generated by simulation-leads via a second survey; these were grouped into themes and finally endorsed by consensus during an in-person meeting of simulation leads. Priority themes were also reviewed by senior simulation educators.

Twenty simulation-leads representing all 14 invited institutions participated in the study between February and May, 2018. Sixty-two active, simulation-based research projects were identified (median per institution = 4.5, IQR 4), as well as six common facilitators and five barriers. Forty-nine priorities for simulation-based research were reported and summarized into eight themes: simulation in competency-based medical education, simulation for inter-professional learning, simulation for summative assessment, simulation for continuing professional development, national curricular development, best practices in simulation-based education, simulation-based education outcomes, and simulation as an investigative methodology.

This study summarized simulation-based research activity in EM in Canada, identified its perceived facilitators and barriers, and built national consensus on priority research themes. This represents the first step in the development of a simulation-based research agenda specific to Canadian EM.

Little is known about how the Royal College of Emergency Medicine (RCEM) residency programs are selecting their residents. This creates uncertainty regarding alignment between current selection processes and known best practices. We seek to describe the current selection processes of Canadian RCEM programs.

An online survey was distributed to all RCEM program directors and assistant directors. The survey instrument included 22 questions and sought both qualitative and quantitative data from the following six domains: application file, letters of reference, elective selection, interview, rank order, and selection process evaluation.

We received responses from 13 of 14 programs for an aggregate response rate of 92.9%. A candidate's letters of reference were identified as the most important criterion from the paper application (38.5%). Having a high level of familiarity with the applicant was the most important characteristic of a reference letter author (46.2%). In determining rank order, 53.8% of programs weighed the interview more heavily than the paper application. Once final candidate scores are established following the interview stage, all program respondents indicated that further adjustment is made to the final rank order list. Only 1 of 13 program respondents reported ever having completed a formal evaluation of their selection process.

We have identified elements of the selection process that will inform recommendations for programs, students, and referees. We encourage programs to conduct regular reviews of their selection process going forward to be in alignment with best practices.

The aim of this study was to describe the clinical and laboratory characteristics of invasive group A streptococcal infections in a geographic area that sees a high volume of cases.

We conducted a health records review of consecutive patients presenting to the Thunder Bay Regional Health Sciences Centre Emergency Department (ED) in 2016–2017 with a diagnosis of invasive group A streptococcal infection using ICD-10 codes. Patient demographics, host characteristics, triage vital signs, laboratory values, culture sites, and disposition were described using univariate and bivariate statistics.

Forty-four adult cases were identified over 2 years, with a median age of 44 years (interquartile range, 35–52). The most prevalent risk factors were diabetes mellitus (45%), current or previous alcohol abuse (39%), and current or previous intravenous drug use (34%). The two most abnormal triage vitals signs were a heart rate ≥ 100 beats per minute in 32 (73%) cases and a respiratory rate ≥ 20 breaths per minute in 27 (63%) cases. The temperature was ≥ 38°C in only 14 (32%) of cases. The C-reactive protein (CRP) was always elevated when measured, and greater than 150 mg/L in 20 (71%) of cases. One-third of patients had an ED visit in the preceding 7 days before the diagnosis of invasive group A Streptococcus.

Invasive group A streptococcal infections often present insidiously in adult patients with mild tachycardia and tachypnea at triage. The CRP was the most consistently abnormal laboratory investigation.

Extracorporeal cardiopulmonary resuscitation in refractory cardiac arrest (ECPR) is an emerging resuscitative therapy that has shown promising results for selected patients who may not otherwise survive. We sought to identify the characteristics of cardiac arrest patients presenting to our institution to begin assessing the feasibility of an ECPR program.

This retrospective health records review included patients aged 18–75 years old presenting to our academic teaching hospital campuses with refractory nontraumatic out-of-hospital or in-emergency department (ED) cardiac arrest over a 2-year period. Based on a scoping review of the literature, both “liberal” and “restrictive” ECPR criteria were defined and applied to our cohort.

A total of 179 patients met inclusion criteria. Median age was 60 years, and patients were predominantly male (72.6%). The initial rhythm was ventricular tachycardia/ventricular fibrillation in 49.2%. The majority of arrests were witnessed (69.3%), with immediate bystander CPR performed on 53.1% and an additional 12% receiving CPR within 10 minutes of collapse. Median prehospital time was 40 minutes (interquartile range, 31–53.3). Two-thirds of patients (65.9%) were identified as having a reversible cause of arrest and favorable premorbid status was identified in nearly three quarters (74.3%). Our two sets of ECPR inclusion criteria revealed that 33 and 5 patients (liberal and restrictive criteria, respectively), would have been candidates for ECPR.

At our institution, we estimate between 6% and 40% of ED refractory cardiac arrest patients would be candidates for ECPR. These findings suggest that the implementation of an ECPR program should be explored.

Podcasts are increasingly being used for medical education. A deeper understanding of usage patterns would inform both producers and researchers of medical podcasts. We aimed to determine how and why podcasts are used by emergency medicine and critical care clinicians.

An international interprofessional sample (medical students, residents, physicians, nurses, physician assistants, and paramedics) was recruited through direct contact and a multimodal social media (Twitter and Facebook) campaign. Each participant completed a survey outlining how and why they utilize medical podcasts. Recruitment materials included an infographic and study website.

390 participants from 33 countries and 4 professions (medicine, nursing, paramedicine, physician assistant) completed the survey. Participants most frequently listened to medical podcasts to review new literature (75.8%), learn core material (75.1%), and refresh memory (71.8%). The majority (62.6%) were aware of the ability to listen at increased speeds, but most (76.9%) listened at 1.0 x (normal) speed. All but 25 (6.4%) participants concurrently performed other tasks while listening. Driving (72.3%), exercising (39.7%), and completing chores (39.2%) were the most common. A minority of participants used active learning techniques such as pausing, rewinding, and replaying segments of the podcast. Very few listened to podcasts multiple times.

An international cohort of emergency clinicians use medical podcasts predominantly for learning. Their listening habits (rarely employing active learning strategies and frequently performing concurrent tasks) may not support this goal. Further exploration of the impact of these activities on learning from podcasts is warranted.

The aim of this study was to describe the sensitivity of various C-reactive protein (CRP) cut-off values to identify patients requiring magnetic resonance imaging evaluation for pyogenic spinal infection among emergency department (ED) adults presenting with neck or back pain.

We prospectively enrolled a convenience series of adults presenting to a community ED with neck or back pain in whom ED providers had concern for pyogenic spinal infection in a derivation cohort from 2004 to 2010 and a validation cohort from 2010 to 2018. The validation cohort included only patients with pyogenic spinal infection. We analysed diagnostic test characteristics of various CRP cut-off values.

We enrolled 232 patients and analysed 201 patients. The median age was 55 years, 43.8% were male, 4.0% had history of intravenous drug use, and 20.9% had recent spinal surgery. In the derivation cohort, 38 (23.9%) of 159 patients had pyogenic spinal infection. Derivation sensitivity and specificity of CRP cut-off values were > 3.5 mg/L (100%, 24.8%), > 10 mg/L (100%, 41.3%), > 30 mg/L (100%, 61.2%), and > 50 mg/L (89.5%, 69.4%). Validation sensitivities of CRP cut-off values were > 3.5 mg/L (97.6%), > 10 mg/L (97.6%), > 30 mg/L (90.4%), and > 50 mg/L (85.7%).

CRP cut-offs beyond the upper limit of normal had high sensitivity for pyogenic spinal infection in this adult ED population. Elevated CRP cut-off values of 10 mg/L and 30 mg/L require validation in other settings.

Our study objective was to describe the Canadian emergency medicine (EM) research community landscape prior to the initiation of a nationwide network.

A two-phase electronic survey was sent to 17 Canadian medical schools. The Phase 1 Environmental Scan was administered to department chairs/hospital EM chiefs, to identify EM physicians conducting clinical or educational research. The Phase 2 Survey was sent to the identified EM researchers to assess four themes: 1) geographic distribution, 2) training/career satisfaction, 3) time/financial compensation, and 4) research facilitators/barriers. Descriptive analyses were conducted, and results were stratified by Canadian regions.

A total of 92 EM researchers were identified in Phase 1; 67 (73%) responded to the Phase 2 Survey. Of those, 42 (63%) reported being clinical researchers, and 19 (45%) had a graduate degree. Three provinces encompassed most of the researchers (n = 35). Of the respondents, 61% had a research degree, 66% felt adequately trained for their research career, 73% had financial support, 83% had access to office spaces, 52% had no mentor during their first years of their career, 69% felt satisfied with their research career, and 82% suggested that they will still be conducting research in 5 years.

EM researchers reported being adequately trained, even though only a little over half had a graduate degree. Only two-thirds had financial support, and mentorship was lacking in one-third of the participants. Not all respondents had a form of infrastructure, but most felt optimistic about their careers. The Canadian EM research environment could be improved to ensure better research capacity.

Health disparities between racial and ethnic groups have been documented in Canada, the United States, and Australia. Despite evidence that differences in emergency department (ED) care based on patient race and ethnicity exist, there are no comprehensive literature reviews in this area. The objective of this review is to provide an overview of the literature on the impact of patient ethnicity and race on the processes of ED care.

A scoping review was conducted to capture the broad nature of the literature. A database search was conducted in MEDLINE/PubMed, EMBASE, CINAHL Plus, Social Sciences Citation Index, SCOPUS, and JSTOR. Five journals and reference lists of included articles were hand searched. Inclusion and exclusion criteria were defined iteratively to ensure literature captured was relevant to our research question. Data were extracted using predetermined variables, and additional extraction variables were added as familiarity with the literature developed.

Searching yielded 1,157 citations, reduced to 153 following removal of duplicates, and title and abstract screening. After full-text screening, 83 articles were included. Included articles report that, in EDs, patient race and ethnicity impact analgesia, triage scores, wait times, treatments, diagnostic procedure utilization, rates of patients leaving without being seen, and patient subjective experiences. Authors of included studies propose a variety of possible causes for these disparities.

Further research on the existence of disparities in care within EDs is warranted to explore the causes behind observed disparities for particular health conditions and population groups in specific contexts.

In Canada, there were over 60,000 long-term care facility patient transfers to emergency departments (EDs) in 2014, with up to a quarter of them being potentially preventable. Each preventable transfer exposes the patient to transport- and hospital-related complications, contributes to ED crowding, and adds significant costs to the health care system. There have been many proposed and studied interventions aimed at alleviating the issue, but few attempts to assess and evaluate different interventions across institutions.

A systematic search of MEDLINE, CINAHL, and EMBASE for studies describing the impact of interventions aimed at reducing preventable transfers from long-term care facilities to EDs on ED transfer rate. Two independent reviewers screened the studies for inclusion and completed a quality assessment. A tabular and narrative synthesis was then completed. This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews (PRISMA-ScR) guidelines.

A total of 26 studies were included (Cohen's k = 0.68). One was of low quality (Cohen's k = 0.58). Studies were summarized into five themes based on intervention type: Telemedicine, Outreach Teams, Interdisciplinary Care, Integrated Approaches, and Other. Effective interventions reported reductions in ED transfer rates post intervention ranging from 10 to 70%. Interdisciplinary health care teams staffed within long-term care facilities were the most effective interventions.

There are several promising interventions that have successfully reduced the number of preventable transfers from long-term care facilities to EDs in a variety of health care settings. Widespread implementation of these interventions has the potential to reduce ED crowding in Canada.

Conferences are designed for knowledge translation, but traditional conference evaluations are inadequate. We lack studies that explore alternative metrics to traditional evaluation metrics. We sought to determine how traditional evaluation metrics and Twitter metrics performed using data from a conference of the Canadian Association of Emergency Physicians (CAEP).

This study used a retrospective design to compare social media posts and tradition evaluations related to an annual specialty conference. A post (“tweet”) on the social media platform Twitter was included if it associated with a session. We differentiated original and discussion tweets from retweets. We weighted the numbers of tweets and retweets to comprise a novel Twitter Discussion Index. We extracted the speaker score from the conference evaluation. We performed descriptive statistics and correlation analyses.

Of a total of 3,804 tweets, 2,218 (58.3%) were session-specific. Forty-eight percent (48%) of all sessions received tweets (mean = 11.7 tweets; 95% CI of 0 to 57.5; range, 0–401), with a median Twitter Discussion Index score of 8 (interquartile range, 0 to 27). In the 111 standard presentations, 85 had traditional evaluation metrics and 71 received tweets (p > 0.05), while 57 received both. Twenty (20 of 71; 28%) moderated posters and 44% (40 of 92) posters or oral abstracts received tweets without traditional evaluation metrics. We found no significant correlation between Twitter Discussion Index and traditional evaluation metrics (R = 0.087).

We found no correlation between traditional evaluation metrics and Twitter metrics. However, in many sessions with and without traditional evaluation metrics, audience created real-time tweets to disseminate knowledge. Future conference organizers could use Twitter metrics as a complement to traditional evaluation metrics to evaluate knowledge translation and dissemination.
