What I meant is that I can follow it for myself, not do it for others. I don't have the training to know every medical decision tree by heart, but I can look up ones for problems I have and apply them.

I am a bit biased because I have several medical professionals in my family, but a common refrain is definitely that most doctors/nurses aren't going to be that engaged and helpful, and are more of a input/output device to navigate rather than someone you want to completely defer to.
