To quantify the effect of family medicine resident physicians on emergency department (ED) wait times and patients leaving without being seen or treated.

In a medium-volume community ED over twelve months, we used retrospective chart review to compare wait times between patients seen during shifts where staff were working alone versus with a resident. We measured the time from initial triage time to physician initial assessment (T1) and disposition time (LOS), and number of patients leaving without being seen or treated.

In our analysis, 21,141 patients (91% of total visits) were included; 48% were in the staff-with-resident group, and 52% were in the staff-only group. Mean T1 in the resident group was significantly shorter than the staff-only group (1 hour 23 minutes versus 1 hour 38 minutes, difference 15 minutes, 95% CI 13 to 17 minutes, p<0.001). Mean total LOS in the resident group was also reduced (2 hours 38 minutes versus 2 hours 50 minutes, difference 12 minutes, 95% CI 8 to 17 minutes, p<0.001). Fewer patients left without being seen in the resident group than the staff only group (2.8% versus 4.9%, p<0.001). There were no differences in patients leaving without being treated (0.5% versus 0.5%).

This is the first study to demonstrate that residents are associated with a reduction in ED wait times and patients leaving without being seen in a low-acuity, community hospital, compared to previous studies demonstrating no difference or increased wait times.

A recent mixed-methods study on the state of emergency medical services (EMS) research in Canada led to the generation of nineteen actionable recommendations. As part of the dissemination plan, a survey was distributed to EMS stakeholders to determine the anticipated impact and feasibility of implementing these recommendations in Canadian systems.

An online survey explored both the implementation impact and feasibility for each recommendation using a five-point scale. The sample consisted of participants from the Canadian National EMS Research Agenda study (published in 2013) and additional EMS research stakeholders identified through snowball sampling. Responses were analysed descriptively using median and plotted on a matrix. Participants reported any planned or ongoing initiatives related to the recommendations, and required or anticipated resources. Free text responses were analysed with simple content analysis, collated by recommendation.

The survey was sent to 131 people, 94 (71.8%) of whom responded: 30 EMS managers/regulators (31.9%), 22 researchers (23.4%), 15 physicians (16.0%), 13 educators (13.8%), and 5 EMS providers (5.3%). Two recommendations (11%) had a median impact score of 4 (of 5) and feasibility score of 4 (of 5). Eight recommendations (42%) had an impact score of 5, with a feasibility score of 3. Nine recommendations (47%) had an impact score of 4 and a feasibility score of 3.

For most recommendations, participants scored the anticipated impact higher than the feasibility to implement. Ongoing or planned initiatives exist pertaining to all recommendations except one. All of the recommendations will require additional resources to implement.

Societal aging is expected to impact the use of emergency medical services (EMS). Older adults are known as high users of EMS. Our primary objective was to quantify the rate of EMS use by older adults in a Canadian provincial EMS system. Our secondary objective was to compare those transported to those not transported.

We analysed data from a provincial EMS database for emergency responses between January 1, 2010 and December 31, 2010 and included all older adults (≥65 years) requesting EMS for an emergency call. We described EMS use in relation to age, sex, and resources.

There were 30,653 emergency responses for older adults in 2010, representing close to 50% of the emergency call volume and an overall response rate of 202.8 responses per 1,000 population 65 years and older. The mean age was 79.9±8.5 years for those 57.3% who were female. The median paramedic-determined Canadian Triage and Acuity Scale (CTAS) score was 3 and the mean on-scene time was 24.2 minutes. Non-transported calls (12.3%) for the elderly involved predominantly (54.9%) female patients of similar mean age (78.3 years) but lower acuity (CTAS 5) and longer average on-scene times (32.6 minutes).

We confirmed the increasingly high rate of EMS use with age to be consistent with other industrialized populations. The low-priority and non-transport calls by older adults consumed considerable resources in this provincial system and might be the areas most malleable to meet the challenges facing EMS systems.

To examine sociodemographic variations among children <18 years in (1) rates of self-harm visits to emergency departments (EDs) and (2) physician follow-up after the self-harm visit in Alberta.

A retrospective, population-based cohort (2002–2011) of ED visits for self-harm by individuals <18 years was conducted using administrative databases from Alberta, Canada. Individuals were grouped by First Nations status or type of health care premium subsidy (family receipt of government subsidy, human services program subsidy, no subsidy received). Visits from 104 EDs were summarized by crude and directly standardized visit rates (DSVRs) per 100,000 individuals. Kaplan-Meier estimates for median estimated time to physician follow-up were calculated with 95% confidence intervals (CIs).

During the study period, visit rates decreased with the exception of children from families receiving government-sponsored program subsidy (DSVRs 163/100,000 to 250/100,000; p=0.032). First Nations children had disproportionately fewer follow-up visits compared to other children. The median time to follow-up for First Nations children was 39 days (95% CI: 32, 48) compared to 16 days for children from families receiving no subsidy (95% CI: 14, 19), who had the shortest follow-up time after an ED visit.

Sociodemographic differences were evident in ED visit rates as well as the number of and time to physician follow-up visit. The disparities experienced by First Nations children in the follow-up period highlight an opportunity for culturally-grounded risk and needs assessment in the ED to determine and facilitate timely and appropriate follow-up care.

Under-treatment of children’s pain in the emergency department (ED) can have many detrimental effects. Emergency medicine (EM) residents often manage pediatric pain, but their educational needs and perspectives have not been studied.

A novel online survey was administered from May to June 2013 to 122 EM residents at three Canadian universities using a modified Dillman methodology. The survey instrument captured information on training received in pediatric acute pain management, approach to common painful presentations, level of comfort, perceived facilitators, and barriers and attitudes towards pediatric pain.

56 residents participated (46%), 25 of whom (45%) indicated they had not received any training in pediatric pain assessment. All levels of residents reported they were uncomfortable with pain assessment in 0-2 year olds (p=0.07); level of comfort with assessment increased with years of training for patients aged 2-12 years (p=0.02). When assessing children with disabilities, 83% of respondents (45/54) indicated they were ‘extremely’ or ‘somewhat’ uncomfortable. Sixty-nine percent (38/55) had received training on how to treat pediatric pain. All residents reported they were more comfortable using pain medication for a 9 year old, as compared to a 1 year old (oral oxycodone p<0.001, oral morphine p<0.001, IV morphine p=0.004). The preferred methods to learn about children’s pain management were role-modeling (61%) and lectures (57%). The top challenges in pain management were with non-verbal, younger, or developmentally delayed patients.

Canadian EM residents report receiving inadequate training in pediatric pain management, and are particularly uneasy with younger or developmentally disabled children. Post-graduate curricula should be adjusted to correct these self-identified weaknesses in children’s pain management.

Elderly patients often present to the emergency department (ED) with non-specific complaints. Previous studies indicate that such patients are at greater risk for life-threatening illnesses than similarly aged patients with specific complaints. We evaluated the diagnoses and outcomes of elderly patients presenting with non-specific complaints.

Two trained data abstractors independently reviewed all records of patients over 70 years old presenting (to two academic EDs) with non-specific complaints, as defined by the Canadian Emergency Department Information System (CEDIS). Outcomes of interest were ED discharge diagnosis, hospital admission, length of stay, and ED revisit within 30 days.

Of the 743 patients screened for the study, 265 were excluded because they had dizziness, vertigo, or a specific complaint recorded in the triage notes. 419 patients (87.7%) presented with weakness and 59 patients (12.3%) presented with general fatigue or unwellness. The most common diagnoses were urinary tract infection (UTI) (11.3%), transient ischemic attack (TIA) (10.0%), and dehydration (5.6%). There were 11 hospital admissions with median length of stay of five days. Eighty-one (16.9%) patients revisited the ED within 30 days of discharge. Regression analysis indicated that arrival to the ED by ambulance was independently associated with hospital admission.

Our results suggest that elderly patients presenting to the ED with non-specific complaints are not at high risk for life-threatening illnesses. The most common diagnoses are UTI, TIA, and dehydration. Most patients can be discharged safely, although a relatively high proportion revisit the ED within 30 days.

Many patients are seen in the emergency department (ED) for hypertension, and the numbers will likely increase in the future. Given limited evidence to guide the management of such patients, the practice of one’s peers provides a de facto standard.

A survey was distributed to emergency physicians during academic rounds at three community and four tertiary EDs. The primary outcome measure was the proportion of participants who had a blood pressure (BP) threshold at which they would offer a new antihypertensive prescription to patients they were sending home from the ED. Secondary outcomes included patient- and provider-level factors associated with initiating an antihypertensive based on clinical vignettes of a 69-year-old man with two levels of hypertension (160/100 vs 200/110 mm Hg), as well as the recommended number of days after which to follow up with a primary care provider following ED discharge.

All 81 surveys were completed (100%). Half (51.9%; 95% CI 40.5-63.1) of participants indicated that they had a systolic BP threshold for initiating an antihypertensive, and 55.6% (95% CI 44.1-66.6) had a diastolic threshold: mean systolic threshold was 199 mm Hg (SD 19) while diastolic was 111 mm Hg (SD 8). A higher BP (OR 12.9; 95% CI 7.5-22.2) and more patient comorbidities (OR 3.0; 95% CI 2.1-4.3) were associated with offering an antihypertensive prescription, while physician years of practice, certification type, and hospital type were not. Participants recommended follow-up care within a median 7.0 and 3.0 days for the patient with lower and higher BP levels, respectively.

Half of surveyed emergency physicians report having a BP threshold to start an antihypertensive; BP levels and number of patient comorbidities were associated with a modification of the decision, while physician characteristics were not. Most physicians recommended follow-up care within seven days of ED discharge.

Emergency medical services (EMS) programs, which provide an alternative to traditional EMS dispatch or transport to the emergency department (ED), are becoming widely implemented. This scoping review identified and catalogued all outcomes used to measure such alternative EMS programs.

Broad systematized bibliographic and grey literature searches were conducted.

Inclusion criteria were 911 callers/EMS patients, reported on alternatives to traditional EMS dispatch OR traditional EMS transport to the ED, and reported an outcome measure.

The reports were categorized as either alternative to dispatch or to EMS transport, and outcome measures were categorized and described.

The bibliographic search retrieved 13,215 records, of which 34 articles met the inclusion criteria, with an additional 10 added from reference list hand-searching (n=44 included). In the grey literature search, 31 websites were identified, from which four met criteria and were retrieved (n=4 included). Fifteen reports (16 studies) described alternatives to EMS dispatch, and 33 reports described alternatives to EMS transport. The most common outcomes reported in the alternatives to EMS dispatch reports were service utilization and decision accuracy. Twenty-four different specific outcomes were reported. The most common outcomes reported in the alternatives to EMS transport reports were service utilization and safety, and 50 different specific outcomes were reported.

Numerous outcome measures were identified in reports of alternative EMS programs, which were catalogued and described. Researchers and program leaders should achieve consensus on uniform outcome measures, to allow benchmarking and improve comparison across programs.

Does a hemoglobin transfusion threshold of 70 g/L yield better patient outcomes than a threshold of 90 g/L in patients with acute upper gastrointestinal bleeding?

Villanueva C, Colomo A, Bosch A, et al. Transfusion strategies for acute upper gastrointestinal bleeding. N Engl J Med 2013;368(1):11-21.

The authors of this study measured mortality, from any cause, within the first 45 days, in patients with acute upper gastrointestinal bleeding, who were managed with a hemoglobin threshold for red cell transfusion of either 70 g/L or 90 g/L. The secondary outcome measures included rate of further bleeding and rate of adverse events.

To characterize the current state of Canadian emergency medicine (EM) resident research and develop recommendations to promote excellence in this area.

We performed a systematic review of MEDLINE, Embase, and ERIC using search terms relevant to EM resident research. We conducted an online survey of EM residency program directors from the Royal College of Physicians and Surgeons of Canada (RCPSC) and College of Family Physicians of Canada (CFPC). An expert panel reviewed these data, presented recommendations at the Canadian Association of Emergency Physicians 2014 Academic Symposium, and refined them based on feedback received.

Of 654 potentially relevant citations, 35 articles were included. These were categorized into four themes: 1) expectations and requirements, 2) training and assessment, 3) infrastructure and support, and 4) dissemination. We received 31 responses from all 31 RCPSC-EM and CFPC-EM programs. The majority of EM programs reported requiring a resident scholarly project; however, we found wide-ranging expectations for the type of resident research performed and how results were disseminated, as well as the degree of completion expected. Although 93% of RCPSC-EM programs reported providing formal training on how to conduct research, only 53% of CFPC-EM programs reported doing so. Almost all programs (94%) reported having infrastructure in place to support resident research, but the nature of support was highly variable. Finally, there was marked variability regarding the number of resident-published abstracts and manuscripts.

Based on the literature, our national survey, and discussions with stakeholders, we offer 14 recommendations encompassing goals, expectations, training, assessment, infrastructure, and dissemination in order to improve Canadian EM resident research.
