Pediatric Emotional Distress Reference System (PEDRS) Mobile App.

The Pediatric Emotional Distress Reference System (PEDRS) serves as a quick reference guide to be employed in the field. The guide identifies common distress reactions by developmental level with age-appropriate calming and distraction activities. The PEDRS is cross-referenced with the BroselowTM and HandTevyTM weights and colors to help medical providers determine approximate a child's age when that information is not available. This electronic version was created to allow providers to better access the guide.

About the app

Supporting children in distress can pose particular challenges for providers, whether delivering emergency medical services, responding to a disaster, or providing daily care. Children have unique physical differences, developmental needs, and distress reactions that providers may find difficult to address. They can trigger responders' own emotions, interfering with their information processing and decision-making abilities. Providers have reported that their own emotional responses, their lack of experience working with kids, and the emotions of family members can negatively impact the quality of care that they are able to provide when working with children in distress.

The Engage - Calm - Distract curriculum developed was developed by the Colorado Department of Public Health and Environment (CDPHE) to address these challenges. With it comes the Pediatric Emotional Distress Reference System (PEDRS). This app version was developed in collaboration with the University of Colorado.

How to use the app

The PEDRS mobile app has a simple interface where the user can select a child's developmental level and then view corresponding information related to the child's potential reactions to distress, calming techniques, and distraction ideas.
