Purpose: A new limp or refusal to weight-bear are common symptoms in children presenting to the pediatric emergency department (ED). This poses a diagnostic challenge, particularly among toddlers and nonverbal patients. Point-of-care ultrasound (PoCUS) used by pediatric emergency medicine physicians may detect hip effusion, which dramatically aids diagnostic workup and management. There is limited literature regarding the accuracy of hip PoCUS conducted by pediatric emergency medicine physicians. This study aims to assess the diagnostic performance of pediatric emergency medicine physician-performed PoCUS in identifying hip effusion.

Methods: This prospective study was conducted in a single-center pediatric ED. Children presenting with limb pain or new limp were evaluated by pediatric emergency medicine physicians who also performed hip PoCUS and categorized findings as either "effusion" or "no effusion" based on standard sonographic definitions. Patients also underwent radiology department ultrasound reviewed by a pediatric radiologist. Diagnostic test characteristics with corresponding 95% confidence intervals (CI) were calculated using radiology department ultrasound findings as the reference standard.

Results: A total of 95 patients were enrolled by 8 pediatric emergency medicine physicians. Excellent agreement was observed between PoCUS performed by pediatric emergency medicine physicians and radiology department ultrasound for the presence or absence of hip effusion (kappa = 0.81 [95% CI 0.70-0.93]). Hip effusion was identified by PoCUS in 44 out of 49 effusion-positive patients, with a sensitivity of 89.8% (95% CI 77.7-96.6%), specificity of 91.3% (95% CI 79.2%-97.5%), positive likelihood ratio of 10.33 (95% CI 4.03-26.47), and negative likelihood ratio of 0.11 (95% CI 0.05-0.26).

Conclusion: PoCUS performed by pediatric emergency medicine physicians has reasonably high sensitivity and specificity for diagnosing hip effusion among pediatric patients presenting to the pediatric ED with a limp or leg pain. This practice may potentially expedite both diagnosis and treatment within this patient population.

Objective: Caregivers with low health literacy are more likely to overestimate illness severity and have poor adherence with health-promoting behaviors. Our primary objective was to relate caregiver health literacy to the urgency of emergency department (ED) utilization. The secondary objective was to explore the relationship between social and demographic characteristics, health literacy, and urgency of ED use.

Methods: This sub-study was a descriptive cross-sectional survey with health record review. Data were collected from ten Canadian pediatric EDs. Study variables included demographics, visit details, and the Newest Vital Sign measurement of health literacy. ED visits were classified as urgent or non-urgent based on the resource utilization method.

Results: The response rate was 97.6% (n = 2005). Mean (SD) caregiver age was 37.0 (7.7) years, 74.3% (n = 1950) were mothers, 72.6% (n = 1953) spoke English as a primary language, 51.0% (n = 1946) had a university degree, and 45.1% (n = 1699) had a household income greater than $100,000. The mean (SD) age of the children was 5.9 (5.0) years and 48.1% (n = 1956) were female. 43.7% (n = 1957) of caregivers had low health literacy. Being a caregiver with a child < 2 years old [aOR 1.83 (1.35, 2.48)] and low health literacy [aOR 1.56 (1.18, 2.05)] were associated with greater non-urgent pediatric ED use. Interprovincial variation was evident: Quebec caregivers were less likely to use the pediatric ED for non-urgent presentations compared to Alberta, while those in Nova Scotia, Manitoba, British Columbia, and Ontario were more likely compared to Alberta.

Conclusion: Almost half of caregivers presenting to Canadian pediatric EDs have low health literacy, which may limit their ability to make appropriate healthcare decisions for their children. Low caregiver health literacy is a modifiable factor associated with increased non-urgent ED utilization. Efforts to address this may positively influence ED utilization.

Purpose: This cohort study aimed to investigate resident physician productivity in an academic emergency department (ED) and assess the impact of longitudinal coaching relationships known as clinical coaching teams and co-learners (medical students) on resident productivity.

Methods: Data from patient visits to two academic EDs in Ottawa, Canada between April 2022 and March 2023 were analyzed. The attending physician schedule, learner arrangements, and patient ED treatment team information were collected. The presence or absence of clinical coaching teams was also recorded. Mean productivity, measured as patients per hour, was calculated for different shifts and learner arrangements. Linear regression and paired t tests were performed for analysis across ambulatory and non-ambulatory settings, with a focus on productivity differences across residents' training programs and level of training.

Results: A total of 142,386 ED visits were included in the analysis across 8161 attending physician shifts. Resident productivity increased with each year of training, with Royal College of Physicians and Surgeons of Canada emergency medicine residents being the most productive by year 5. There was no significant difference in productivity between residents on clinical coaching team shifts compared to non-clinical coaching team shifts. Productivity decreased slightly when residents worked with medical students as co-learners. There was no significant relationship between the difference in productivity on shifts with and without a medical student and year of training.

Conclusions: This study is the first of its kind to describe resident physician productivity in a Canadian emergency department. The results of this study demonstrate that resident physician productivity improves with seniority, and that co-learners and clinical coaching teams do not significantly impact productivity. This information will be useful to program directors and residents to help set realistic expectations around productivity and to ED physician leads in planning service delivery for patients in the context of a training program.

Purpose: This study aimed to examine how different learner arrangements affect the number of patients seen per hour by staff emergency physicians in ambulatory and non-ambulatory zones of two tertiary teaching hospitals in Ottawa, Canada.

Methods: This was a retrospective cohort study analyzing all emergency department (ED) shifts at the Civic and General Campus EDs of The Ottawa Hospital from April 2022 to March 2023. Data collected included shift type (ambulatory or non-ambulatory), learner arrangement, and number of patients seen per hour. Descriptive statistics and two-sample, two-tailed t tests to analyze the relationship between patients seen per hour and learner arrangements.

Results: We analyzed 8161 shifts over the study period, including 5233 in ambulatory care and 2928 in non-ambulatory care areas. Among ambulatory care shifts, the average number of patients seen per hour was 2.1 (95% CI 2.1-2.1) when working alone, 1.9 (1.9-2.0, p < 0.001) with a medical student, 2.1 (2.1-2.2, p = 0.20) with a junior resident, 2.6 (2.5-2.6, p < 0.001) with a senior resident, 2.1 (2.1-2.2, p = 0.33) with a junior resident and a medical student, and 2.6 (2.5-2.7, p < 0.001) with a senior resident and a medical student. In non-ambulatory care shifts, the average number of patients seen per hour was 1.4 (95% CI 1.3-1.5) when working alone (122 shifts, 4%), 1.4 (1.4-1.5, p = 0.63) with a medical student (85 shifts, 3%), 1.5 (1.5-1.5, p = 0.02) with a junior resident (1,013 shifts, 35%), 1.8 (1.7-1.8, p < 0.001) with a senior resident (682 shifts, 23%), 1.6 (1.5-1.6, p < 0.001) with a junior resident and a medical student (683 shifts, 23%), and 1.8 (1.7-1.8, p < 0.001) with a senior resident and a medical student (343 shifts, 12%).

Conclusion: This study highlights the significant impact that learner arrangements have on staff physician productivity in the ED. These findings underscore the importance of strategic scheduling to optimize patient throughput.
