A healthcare AI demonstration needs evidence for the claimed task
Match the supplier’s evidence to the actual users, workflow and consequences before evaluating a purchase.

A convincing demonstration answers a narrow question
WHO's 2024 guidance discusses inaccurate outputs and automation bias in large multimodal health AI. These general concerns do not determine the performance or regulatory status of a specific product. They do make it important to ask exactly what a demonstration has shown and which intended use remains untested.
A supplier may present a successful example selected in advance. That establishes that the example can work under those conditions. It does not establish dependable performance across your organization's users, documents or difficult cases, and it should not be described as a complete validation.
Write the intended task before reviewing evidence
Specify the input, the proposed output, the person who checks it and the action that may follow. Keep administrative assistance, information retrieval and clinical decision support distinct. Each has different requirements, and evidence for one cannot simply be reused to justify the others.
Ask qualified internal reviewers to define acceptance conditions appropriate to the task. The purchasing team should not create a clinical performance threshold without the necessary expertise.
Inspect the comparison and limitations
Request information about the evaluated population, setting, comparator and failure cases. Determine whether results come from a controlled evaluation, ordinary deployment or selected demonstrations. Ask what was excluded and whether the evidence concerns the current product version.
Keep uncertainty visible when evidence is unavailable. A missing result is a gap to resolve, not proof that the product fails and not permission to assume that it succeeds.
Include human behavior in the evaluation
Where a supervised trial is appropriate, examine whether users check the output as intended and whether the interface encourages unwarranted confidence. A requirement for human review has limited practical value if the workflow makes the supporting evidence hard to access or gives staff no time to inspect it.
Evaluate escalation and correction with the responsible professionals. Do not treat a warning label as equivalent to an observed recovery process.
Make procurement contingent on the evidence
Document which claims are supported, which are supplier assertions and which remain unresolved. Any implementation decision should follow the organization's applicable professional and governance processes. Retain the ability to restrict scope if the evidence supports only a narrower use.
This article is an evidence-assessment framework, not clinical advice or product certification. WHO supplies the governance context; the organization's intended task determines the evidence it needs before an attractive demonstration can become a justified operational purchase.
