The goal of this clinical trial is to improve emergency care of children in Manitoba by increasing the weighted pediatric readiness scores (WPRS) of the general EDs through the implementation of provincially derived interventional measures (PDIM). Investigators want to test the effects of PDIM on the general EDs in Manitoba. The main questions it aims to answer are:

• What is the magnitude and direction of the effect of implementing PDIM on baseline WPRS of the general EDs, if any?
• Which implementation strategies effectively support the full incorporation of PDIM to increase the WPRS of general EDs across Manitoba? The participating general EDs will be asked to
• Gather individuals providing emergency care in their centers for training and education around PDIM.
• Select a lead person who will act as the general ED Champion.

Description Investigators defined the inclusion and exclusion criteria using the PICO framework. They will implement a prospective single-blinded RCT involving 17 gEDs. The entire study will be coordinated at the Children's Hospital Research Institute of Manitoba. Investigators will assess for compliance in a scheduled pattern after the education and training sessions using a checklist. They will also sample all the 17 gEDs via RedCap link, post intervention.

PDIM is composed of 3 components. (1) Customized report to the gEDs and discussion with the gEDs on the gaps identified (1.5hrs/session x 2). (2) Pediatric resource toolkits availability via Translating Emergency Knowledge for Kids (TREKK). (3) Ongoing interactions, and intensive training (2.5hrs/session x 1) and education sessions. The gEDs in the control group will receive only the first component of the 3 components of PDIM.

Randomization Investigators have completed the randomization of anonymized 17 of the 28 gEDs. Randomization was performed using an R statistical software program into intervention (n=9) versus control (n=8), in a ratio of 1:1 within pairs. The gEDs were paired using a hierarchical cluster analysis based on the baseline WPRS, ED volume and ED location.

Survey The validated survey (n/100) will collect information around the six domains of the gEDs post intervention including coordination of patient care, ED staffing and training, quality improvement, patient safety, policies and procedures, and availability of pediatric equipment/supplies.

Data management and statistical analysis Phase 1 Frequentist approach - The investigators will perform a meta-analysis to generate a forest plot showing the mean change in WPRS of gEDs with 95% CI. The association between the change in WPRS and types of intervention will be examined in random-effects models.

Phase 2 & Phase 3 Frequentist approach - Investigators will perform a descriptive analysis on the baseline characteristics of participating gEDs. The difference in baseline characteristics of the gEDs between intervention and control groups will be assessed using Pearson χ2 or Fisher exact test for categorical data and t-test/Mann-Whitney U for continuous variables. The difference between the baseline WPRS and post intervention WPRS of the gEDs will be compared using paired-sample t-tests.

Bayesian approach - The intervention effect will be estimated using a vague prior called Cauchy, as will the other parameters in the fully Bayesian model. Investigators will report the posterior probability of a positive finding using a threshold effect size greater than 5, Pr(Effect > 0 | data), and also with an effect size greater than 7, Pr(Effect > 7 | data).

Sample size estimation - Investigators assumed an optimistic prior for the intervention effect to be a Cauchy distribution centered at 10, representing 80% certainty that the effect size is between 7 and 10.

Significance of research:

Implementing PDIM will help address the gaps identified in the gEDs in Manitoba. This study has the potential of increasing overall WPRS, which has been shown to have a strong inverse correlation with pediatric mortality. It will improve acute care for children regardless of the location of the gED in Manitoba.
