Patients’ concerns about medical AI are not one simple objection, and the evidence does not show that most patients reject every AI tool. People may be unsure whether an output is accurate, how it was produced, what happens to their health data, or who is answerable if it is wrong. Many also want AI to support—not replace—their clinician. Those concerns point to a practical condition for trust: people need to understand the tool’s role and limits, retain a meaningful human relationship, and know who is responsible for its use.

Do most patients distrust medical AI?

Not necessarily. Attitudes vary by question, setting, and sample. A 2025 multinational survey of 13,806 hospital patients at 74 hospitals in 43 countries found that 57.6% had a generally positive view of AI in health care. Yet fewer than half expressed positive attitudes across all the survey’s trust items. In the reported measures, 70.2% preferred explainable AI and 72.9% preferred physician-led decisions, even if that meant slightly compromised accuracy.

The survey used a nonprobability hospital-based sample collected from February 1 to November 1, 2023. It is useful evidence that general openness and reservations about trust can coexist, but it is not a representative poll of everyone in the world. “Most patients don’t trust medical AI” is therefore too broad as a factual claim. A more accurate account is that many people have specific conditions they want met before they rely on it.

What makes medical AI difficult to trust?

Patients may not be able to judge an answer

When a tool gives a diagnosis or recommendation without making clear what information and evidence shaped it, patients may struggle to tell whether the result is sound, current, or relevant to their case. The Agency for Healthcare Research and Quality (AHRQ) describes the “black box” problem as a lack of transparency about the inputs and algorithms used to generate an AI output. An explanation can help, but it cannot by itself prove that a system is accurate or suitable for a particular patient.

Participants in AHRQ’s 2024 Trust and Patient-Centeredness Workgroup discussions also worried that an AI tool might miss relevant information or fail to handle a serious health concern appropriately. Their concerns included whether the tool relied on accurate, current evidence. These were themes from three small-group discussions in January and February 2024—not estimates of how common each concern is among patients.

People may wonder whether the data represents them

AI systems learn from data, so patients may ask whether the information used to build or tailor a tool reflects people like them. If a group is underrepresented, patients can reasonably worry that the system may work less well for them. One AHRQ discussion participant put the concern this way: “The tools are only as good as the information that they have and the information that they’re being trained on. As long as there’s lack of information, there’s major concerns for how that’s going to impact certain groups.” That comment illustrates a concern; it does not establish how often the problem occurs in deployed systems.

Data access and control can feel unclear

Patients may not know what health information an AI tool uses, where it is stored, who can access it, or whether it can be shared or used for other purposes. A 2026 Coalition for Health AI release summarizing a NORC at the University of Chicago survey using its AmeriSpeak probability-based panel reported that data commercialization raised more alarm than algorithmic bias in the survey results. The release also reported that 93% of respondents had at least one concern. These figures should be attributed to that survey as summarized by the coalition, not treated as timeless facts about patients generally.

It may be unclear who is accountable

If an AI recommendation contributes to a harmful decision, patients need to know who is responsible for reviewing it and addressing the consequences. The 2026 Coalition for Health AI release said more than 80% of respondents believed clear accountability measures would increase trust. That finding suggests that disclosure alone may not answer the deeper question: who oversees the tool and takes responsibility for its use?

People may fear losing the clinician, not just question the algorithm

For many patients, care involves being heard, asking questions, and discussing options with a clinician. A system that appears to replace that relationship—or a clinician who accepts its output without scrutiny—can undermine confidence. AHRQ’s 2024 discussions found that participants saw AI as a supplement to care, and some said that introduction by a trusted clinician or health system could make acceptance more likely. One participant explained the value of clear disclosure: “I don’t want the bot to chat like a human because I want to know when I’m talking to a bot.”

What do people say they want from medical AI?

Survey preferences help show what could make an AI-assisted encounter more acceptable, though stated preferences are not proof that a system will be safe or trusted in real-world use.

Evidence What respondents preferred or reported How to interpret it
2025 multinational hospital survey; 13,806 patients in 43 countries 70.2% preferred explainable AI; 72.9% preferred physician-led decision-making in the reported measures. A nonprobability hospital sample measured attitudes, not clinical outcomes or universal opinion. Study
2025 US conjoint survey; 3,000 adults Respondents were more likely to choose hypothetical diagnosis visits with better AI performance, clinician presence, governance signals such as FDA approval or certification, and disclosed representative training data. These were choices among hypothetical scenarios, not evidence that any one signal guarantees safe care or durable trust. Study
2026 Coalition for Health AI release summarizing NORC/AmeriSpeak survey findings 75% said they use AI; 13% said they felt very comfortable with it; 51% said AI makes them trust health care less, while 12% said it increases trust. These are figures as reported in the coalition’s release. The release is a summary; consult the full report for exact wording and detailed methodology before making fine-grained comparisons. Release

Across these findings, preferences are not reducible to “AI or no AI.” People may be open to a tool when it performs well and is governed responsibly, while still wanting a clinician involved and clear information about how the tool works.

What should patients be told about an AI tool?

A useful explanation should answer practical questions in plain language, before the AI meaningfully shapes a care decision. AHRQ’s implementation guidance highlights patient engagement, education, transparency, ongoing monitoring, and human review. For a specific system, patients can ask:

  • Is AI being used? Identify when an automated tool is involved, rather than making it seem like a person is responding.
  • What is it being used for? Clarify whether it helps organize information, suggests a diagnosis, supports a clinician’s decision, or performs another task.
  • What information does it use? Explain the relevant patient data and the evidence behind its output, including known limits where they are established.
  • Who can access or share my data? Describe data access, storage, retention, and sharing in terms patients can understand.
  • Who reviews the result and takes responsibility? Explain whether a clinician checks it, can reject it, and remains accountable for the care decision.
  • Can I ask for a human-led alternative? Make clear what choices are available and how the patient can raise a concern.

These questions are useful prompts, not a guarantee that a system is appropriate. AHRQ notes that human reviewers can assess whether an AI output is clinically relevant in context that a system may not incorporate. AHRQ’s viewpoint on patient-centered clinical decision support discusses explainability, engagement, education, monitoring, and review as implementation practices—not as proof that transparency alone removes distrust.

Why the setting and the patient matter

Trust can depend on the clinical task and the consequences of an error. A tool that helps with a lower-stakes administrative task raises different questions from one that influences diagnosis or treatment. Patients may also bring prior experiences with health care and technology, different levels of comfort with digital tools, and different expectations of the institution introducing the AI.

AHRQ’s 2024 findings came from seven patient and caregiver advocates identified through purposive and convenience sampling. The discussions offer a close look at concerns participants raised, but they cannot show how prevalent those views are across the population. The multinational survey and US hypothetical-choice study add broader evidence, but each has its own limits: one used a nonprobability hospital sample, and the other measured preferences in imagined visits. Attitude surveys do not establish real-world clinical outcomes.

What health systems can do to earn confidence

AHRQ’s executive summary recommends consulting patients and offering choice, educating patients and caregivers, setting standards for transparent and safe implementation, using AI to support clinicians, monitoring tools continuously, examining the data used to tailor outputs, and considering mistrust among historically marginalized or vulnerable populations. Put into practice, those principles mean treating trust as an ongoing responsibility rather than a one-time announcement.

  • Involve patients in decisions about how an AI tool is introduced and used.
  • Keep clinicians engaged in reviewing outputs, applying context, and making care decisions.
  • Explain the tool’s role, inputs, evidence, limits, and data practices in accessible language.
  • Monitor performance after deployment and critically reassess whether it remains appropriate for the patients it serves.
  • Provide a clear route for patients to ask questions, raise concerns, or choose an available alternative.

These practices align with the concerns patients described; they should not be presented as a simple formula that guarantees trust. AHRQ also says more research is needed across populations and after pilot implementations.
