When AI suggests changing a prescription
Bowen Wan was 31. Her parents, Qun Wan and Meiqin Xu, filed a wrongful death lawsuit against OpenAI and its CEO after losing their daughter. They allege that ChatGPT gave Bowen a plan to stop her epilepsy medication, encouraged her to keep it from her doctors, and contributed to her death. Those are her family’s allegations. The complaint presents their account.

What a pause can do for a patient
If you’re worried that a medicine is affecting your memory or how you feel, you deserve time to talk about it. One way to use AI is to turn that worry into a question for your prescriber. Bring the chatbot’s exact reply and ask, “Could my medicine be causing this? What options can we consider safely?” Keep taking seizure medication as prescribed while you contact your care team about any change.
My sixth TEDx talk: The Pause Is the Safety Feature
At TEDxFactoria on November 8, I asked three questions about acting on an AI answer. What did we actually ask? What would change our mind? Who owns the call? For someone building a health tool, that pause can be a design choice. When a patient asks for a dose change, help them write to their prescriber and share the conversation.
Start with your role
Find the guidance you need
Patients and caregivers
Understand where healthcare AI has helped, where it has failed, what questions to ask, and when to involve a qualified clinician.
Clinicians and researchers
Evaluate evidence, intended use, local validity, subgroup performance, workflow fit, and meaningful patient outcomes.
Health system leaders
Build accountable governance with risk tiers, approval gates, monitoring, incident response, and authority to pause unsafe systems.
Evidence before hype
Improve patient care by learning from both success and failure
Healthcare AI can expand access, reduce burden and improve detection. It can also miss cases, worsen unequal access, compromise privacy or lead people to trust incorrect output. We examine the evidence for each use and its consequences for patients.

Governance & Accountability
Start with the intended use, the evidence required, and the person accountable for the decision. Our governance guide connects these questions to validation, monitoring, and escalation.
Human oversight
Human oversight should match the consequence of the task. High impact clinical decisions need qualified review, authority to disagree, usable evidence, and a tested escalation path.
Accountability Frameworks
Who is responsible when AI fails? Establishing clear liability protocols for developers, institutions, and clinicians is our priority.
Bias & Hallucination
LLMs can produce confident factual errors. Test their outputs against verified clinical information before deployment, and investigate patterns that the underlying data do not support.
Auditability
Record intended use, model and data versions, material inputs and outputs, human actions, overrides, incidents, and changes while respecting privacy and security.
AI literacy
Teach people when to trust, question, or stop
Safe use requires judgment about the task and its consequences. These learning paths help patients, clinicians and leaders check important claims and seek qualified help when an error could cause harm.
For patients
Use AI to prepare questions and understand options, while keeping diagnosis and treatment decisions with qualified clinicians.
For clinicians
Check provenance, fit to the patient, missing context, and whether the output changes a consequential decision.
For leaders
Train teams on approved uses, prohibited uses, escalation paths, incident reporting, and performance monitoring.

Use the right framework for the right decision
WHO, NIST, FDA, AMA, and the EU AI Act address different parts of responsible health AI. We map their principles to concrete owners, evidence, controls, and review gates without treating any one framework as universal.
Clinical safety
Define intended use, human review, failure modes, escalation, and evidence needed before deployment.
Governance
Assign accountable owners, document decisions, monitor performance, and maintain an auditable incident process.
Regulatory fit
Determine which rules apply by jurisdiction, product function, risk, and whether the system is regulated medical software.

Frequently asked questions about AI in healthcare
Is this website affiliated with OpenAI?
No. Healthcare AI with Harvey Castro, MD | DR GPT™ is an independent education and governance site founded and led by Harvey Castro, MD, MBA. It is not affiliated with OpenAI or the ChatGPT Health consumer product.
Does this site rank foundation models as good or bad?
No. We evaluate evidence, intended use, workflow, patient impact, and governance controls. The same model can present different risks in different contexts.
Can AI improve patient care?
Yes, in well defined settings AI can support detection, access, documentation, and clinical workflow. Benefits must be measured against false positives, missed cases, inequity, burden, privacy risk, and other downstream effects.
Can healthcare AI cause harm?
Yes. Published examples include weak performance after external validation, biased allocation caused by poor proxy choices, and increased recalls or procedures without clear clinical benefit. That is why local validation and ongoing monitoring matter.
What does meaningful human oversight require?
The reviewer needs appropriate expertise, enough time and information to challenge the output, authority to override it, and a clear escalation path. A required click is not meaningful oversight.
Is this medical or legal advice?
No. This site provides general education. Healthcare decisions require qualified clinical judgment, and governance decisions require review for the specific product, jurisdiction, and organization.
