"JoinTriage" is a triage app for EMS providers.

The time from onset to the start of treatment greatly affects the survival rate and prognosis of stroke and heart disease patients.
The “JoinTriage” app helps paramedics and EMTs quickly and accurately triage patients, ensuring that they receive the care they need as quickly as possible.

JoinTriage provides several assessment scales (FAST-ED, RACE, C-STAT, VAN, etc.) commonly used among EMS providers.
Question responses, such as the onset time, are used to evaluate symptoms of stroke or cardiac disease. The patient’s condition is summarized with a score and accompanied by other useful information such as the probability of severe outcomes, when applicable. A map is presented, showing a list of recommended medical centers best suited to treat the patient (IV tPA, thrombectomy, etc.).

*Types of assessment scales can be changed without prior notice.
*The app uses a curated database of medical centers.

By integrating with Join, a communication app for medical professionals, assessment results can be shared with medical centers.

Why isn’t a hospital in my city - that is a stroke center - listed?

University of Kansas St. Francis campus in Topeka is a primary stroke center. It’s not present in the app when I am looking for treatment. I have to go to Stormont, Lawrence, or Kansas City.

Poor Quality App

I only scored this app one star because I had to select that at a minimum. The application is not evidence based, and is in direct conflict with established guidelines of evaluating suspected stroke patients in the prehospital setting (Cincinnati Prehospital Stroke Screen, MEND Exam). The application does provide the closest stroke facilities (comprehensive versus primary) based on the interpreted severity of the patient, but does not actually link to a navigation service, only displaying a static routing on a map. There are also grammatical errors throughout the different pages. From a field medics point of view this could have been done much better.

Developer Response ,

Thank you for taking time to leave your feedback. We have improved features and design, and newly released "JoinTriage". All available scales are based on published assessment scales. And the app allows you to open other map applications to use navigation service. We hope you will experience new version.

Useful- Jackson EMS

I think one would have to use common sense with regards to the MEND complete stroke testing in the field. It is however a nice tool that the area hospitals have agreed to use. Always treat the pt, not the app.
