The High-Sensitivity HEART Pathway Safely Reduces Hospitalizations Regardless of Sex or Race in a Multisite Prospective US Cohort.

Background: The high-sensitivity HEART pathway (hs-HP) risk stratifies emergency department (ED) patients with chest pain. It is unknown if its safety and effectiveness vary by sex or race.

Methods: We conducted a subgroup analysis of the hs-HP implementation study, a pre-post interrupted time series at five US EDs.

A community-based systems dynamics approach for understanding determinants of children's social and emotional well-being.

We report on our application of a community-based systems dynamics modelling approach to identify key factors affecting children's social and emotional well-being (SEW). Using a group model building process with 31 stakeholders in 2 communities in British Columbia, Canada, we constructed two causal loop diagrams composed of 250 variables, 534 connections and 63 feedback loops. Feedback loops, systems complexity, and prominent systems level variables illustrate the interconnectedness of multilevel determinants influencing children's SEW.
