PATCHS AI analyses patient requests using Deep Learning, which is a kind of Machine Learning. It is not a keyword search, or clinical guideline algorithm.
It has learned how to process patient requests each time a human user (like you) makes a triage decision on actual requests submitted by patients. This means PATCHS can deal with real-world patient health problems, spelling mistakes, and uncertainty - all of which are essential for General Practice!
PATCHS AI has learned from the experience of hundreds of PATCHS users across the country who triage tens of thousands of patient requests each week - i.e. the wisdom of the Crowd. And it's learning more every day - each time you make a triage decision you're teaching PATCHS how to triage similar patient requests in future.
