The earliest trust failures can impact AI success

Key Takeaways

  • Trust in clinical AI systems isn't lost all at once. It happens one disappointment at a time.
  • The most dangerous answer isn't the obviously wrong one. It's the one that sounds right.
  • Clinical AI should be evaluated on how reliably it earns trust among clinicians.
The greatest threat to clinician trust in AI is not always a major error. Clinician confidence can erode through small, repeated failures, reinforcing the need for clinically-grounded AI, supported by regular evaluation.

Healthcare leaders tend to think about trust failures as major events. A patient safety incident, a governance breach, a media headline. But trust rarely fails that way.

Long before an AI system causes a catastrophic mistake, it can begin to create something else: doubt. This might look like:

  • A recommendation that doesn't quite fit the patient.
  • An answer that feels incomplete.
  • A source that's hallucinated or difficult to defend.

None of these moments trigger an escalation process, but they matter.

Trust in clinical AI is built in moments

Clinicians are accountable for the decisions they make. They need support to do their best work. Every time they use AI clinical decision support tools, they’re asking a series of questions, whether consciously or unconsciously:

  • Does this answer make sense?
  • Can I follow the reasoning?
  • Would I defend this recommendation?
  • Would I rely on this tool again?

If the answers are no, trust begins to erode.

Dr. Peter Bonis, Chief Medical Officer of UpToDate stated in a recent webinar: "The earliest trust failure is not necessarily something dramatic... it's just little small frictions and disappointments."

A clinician's gut feeling is one of healthcare's earliest warning systems.

Clinicians develop a feeling for the tools they use every day. They recognize patterns and notice subtle changes long before performance dashboards highlight a problem.

Healthcare operates at the speed of trust. If clinicians don’t trust the AI tools built into their workflow, they will either act without confidence or stop to verify every answer. Neither outcome delivers the efficiency gains healthcare leaders hope AI will provide.

AI tools must intersect with the real world

Alex Tyrell, CTO of UpToDate, recently highlighted a challenge facing every AI developer.

AI systems are typically designed and tested using carefully constructed datasets. But clinical environments are rarely controlled. Healthcare organizations treat different patient populations, operate different workflows, and face different clinical realities.

An AI system can perform well in controlled evaluations and still struggle to earn clinician confidence in real-world practice.

Not all AI is created equal

Tools like UpToDate® Expert AI have clinical trust built in by design. When evaluating different AI options, leaders should be asking:

  • Can the evidence be traced?
  • Is uncertainty communicated honestly?
  • Are outputs monitored and evaluated?
  • Is expert oversight built into the process?
  • Can clinicians understand where recommendations come from?

Ultimately, this isn't just a technology question. It's a trust question.

Dr. Peter Bonis and Alex Tyrell discuss this in a recent webinar. One approaches AI through the lens of clinical confidence; the other through the lens of technical performance.

Both arrive at the same conclusion: trust cannot be assumed at launch. It must be earned repeatedly. And the earliest signals that it's being lost are often much smaller than healthcare leaders expect.
