Read This First: Scope and Safety
This Course Is Orientation, Not Clinical Guidance
Read this before anything else. This course is educational orientation for professionals who need to think clearly about AI in healthcare. It is not clinical guidance, not legal advice, and not a regulatory opinion. No output from an AI system — and nothing written in these lessons — substitutes for professional clinical judgement, your institution's protocols, or the approvals a product needs before it touches patient care. Nothing here should be used to make a decision about an individual patient. Where a lesson describes what a category of tool can do, that is a description of published capability patterns, not a recommendation to deploy it. A real deployment decision requires validation on your own local data plus formal institutional governance sign-off.
- Educational orientation only — no lesson here constitutes clinical, legal, or regulatory advice
- No AI output replaces clinical judgement, institutional protocol, or the relevant regulatory approval
- Deployment is never a reading decision: it requires local validation on your own population and governance sign-off
- This course names capability categories and evidence patterns — it never gives a threshold, dose, protocol, or triage rule you could act on
What You Will Deliberately Not Find Here
Some omissions are intentional. You will not find diagnostic cut-offs, dosing logic, treatment pathways, or triage rules — not because they are secret, but because a general course is the wrong place for anything a reader might apply to a patient without local validation behind it. You will also not find claims that a named commercial product is safe, effective, or approved for your setting. Regulatory status is jurisdiction-specific, version-specific, and intended-use-specific; it changes, and a course cannot track it for you. What you will find is the structure of the field: what the categories of tool are, what evidence exists for each, where that evidence is weak, and what questions to ask before anything reaches a patient.
- No clinical thresholds, protocols, or decision rules — those belong to your institution and its evidence review
- No claims about specific commercial products being approved or effective in your setting
- What you get instead: categories, evidence patterns, failure modes, and the questions that separate a good deployment from a bad one
Saying "The Evidence Is Thin" Is the Point
Healthcare AI is discussed in two registers: vendor optimism and blanket scepticism. Neither is useful to someone who has to make a decision. The honest position varies sharply by application. For some narrow tasks there is substantial published evidence, including prospective work. For others there are mainly retrospective studies on curated datasets, which tell you far less than they appear to. For a few widely promoted applications, the evidence is genuinely thin or mixed, and some well-publicised systems have underperformed badly once studied independently. This course states which is which. Being able to say "we do not know yet" about a specific claim is the most valuable skill it can give you.
- Evidence quality varies by application, not by technology — treat every claim separately
- Retrospective performance on curated data is the weakest common form of evidence, and the most frequently cited
- Independent evaluation has repeatedly deflated systems that looked strong in vendor or single-site studies
- "We do not know yet" is a legitimate, defensible answer in a procurement meeting
Who This Is For
Three audiences, one shared vocabulary. Clinicians and clinical leads need to understand what a tool is doing to their workflow and what it can quietly get wrong. Health-tech builders need to understand why a model that performs well on a benchmark is nowhere near a deployable product, and what regulators and hospitals will ask of them. Administrators and procurement teams need to evaluate claims without being able to read the underlying statistics themselves. None of these roles requires you to be an AI expert. Several lessons include role-specific views so you can read the same material through the lens that matches your job.
- Clinicians: what changes in your workflow, and what fails quietly
- Builders: why benchmark performance is the start of the work, not the end
- Administrators and advisers: how to interrogate a claim without doing the statistics yourself
