DR GPT™ Knowledge Channel

Ask me what I actually think

I am Harvey Castro, MD, MBA. I am a board-certified emergency physician who never stopped seeing patients, and I have spent three years writing about what artificial intelligence really does in medicine. This channel answers from that work, in my words, not from the open internet.

What it answers from

Nearly one hundred essays published on KevinMD since 2023. Seventy articles on this site. My Substack. My books on artificial intelligence in medicine. Talks I have given on stage. Nothing else.

It does not browse the web. It does not borrow another doctor's opinion and put my name on it. If a question falls outside what I have written, it says so rather than inventing an answer.

What it will not do

It is educational, not medical advice.It cannot diagnose you, interpret your results, or tell you what to do about your own health.
It does not replace your clinician.Nothing here creates a doctor-patient relationship. Take real questions to the person who examines you.
Do not send personal health information.This channel is not covered by HIPAA. Keep your own medical details out of it.
If this is an emergency, stop.Chest pain, stroke symptoms, difficulty breathing, thoughts of harming yourself. Call emergency services now. Do not ask a chatbot.

Who it is for

Hospital boards deciding what to buy. Clinicians deciding what to trust. Conference organizers deciding whether my thinking fits their room. Anyone who has read one of my articles and wants to follow the argument further.
