Ash HN: Are There Any Patient-Facing Clinical Decision Support Systems Working?

For chronic or systemic diseases like Advanced Stage Cancer, frequent decisions need to be made about switching therapies, therapy dosage and combinations.

I've read papers which use Machine Learning/Markov Decision Process & Deep Learning techniques being tried out in technology research labs.

Are there any patient-facing systems that can be tried out? (with all due disclaimers in place, holding no one responsible, etc).
