Stated Purpose  

Translating Emergency Knowledge for Kids (TREKK) is a national network working to improve children’s emergency care across Canada (1). Its mission is for TREKK to be the trusted source for easy access to the latest evidence, best practices, user-friendly resources and discussions in pediatric emergency care (2). The app and the website provide a user-friendly directory of links of existing online resources, with a preference for free materials (3).



The app primarily functions as a directory as the vast majority of content requires users to link out to the web for access to materials. PDF copies are sometimes available for download within the app itself, but there are no traditional written entries. Some content appears to be created by TREKK or its affiliates, while the app also links to resources created by other organizations. In addition to PDF documents and internet resources, the app also links to relevant Podcast episodes.

It should be noted that the list of topics covered is not exhaustive but appears to represent common pediatric conditions.

According to the 6.2 version release notes, effort is being made to improve the “provision of instant, offline TREKK content on the mobile app” so that users do not have to rely on connectivity to access content (1). The team can now send important update notifications directly to the app. As of the time of review, online only content was still available throughout in app.


The customization features on this app are limited, however, the app does retain a record of previously downloaded files. French language options are available for some resources. Sharing is integrated within the app, where users can share a PDF or link to various social media platforms, their device contacts or email content to themselves. These features will likely vary depending on the device used.

App’s description states that it can also be used by patients and families.

Part 1: Editorial committee, content updates, and evidence grading

The creators of app are reputable in regard to their affiliations and expertise. However, content advisory members are not listed on every entry. The app does not utilize any grading system, although the TREKK website states that resources are selected based on the knowledge pyramid framework and that “Bottom Line Recommendations” are based on key studies found at the top of the pyramid (highest level of evidence). 

Part 2: Source and authorship information for 3 entries

Since the app functions primarily as a directory, it is difficult to accurately assess the quality of the resources linked, especially if links are broken. In most cases, only a brief description, sometimes a sentence or two, is provided on the resource available for download or linked. Some entries do not have a description at all and just display the links. The app would greatly benefit from providing more information to its users about each resource available. 

Organization of information

The organization of the app is simple and intuitive, however, there are no descriptions on the home page of what type of information each section of the app contains. The following is a list of sections:

  • Bottom Line Recommendations
  • Clinical Pathways and Guidelines
  • PedPacs
  • Podcasts
  • Files
  • Parents and Families


The navigation used in the app is a simple hierarchy. Users click on a main section on the home page, and the subjects contained in each section are listed alphabetically. The specific entries themselves include a link to either download materials or link out to an external website (or both). A back button and home menu are provided throughout the app to navigate other parts of the app.
