The role of assertiveness versus suggestiveness in AI-driven diagnostic support and its differential effects on junior versus senior clinicians’ decision-making

In hospitals, AI tools help doctors understand complex medical data like imaging scans.
But the way AI shares its results can change how doctors make decisions.
There are two main styles of AI communication:

  • Assertive AI Communication: This style gives recommendations strongly and confidently, often like instructions.
  • Suggestive AI Communication: This style shares information more gently, offering advice but leaving the choice to the doctor.

A study with 52 clinicians working in breast imaging looked at how these two AI styles affected diagnosis.

Differences Between Junior and Senior Clinicians

The study found that junior and senior doctors reacted differently to assertive and suggestive AI styles.

  • Junior Clinicians (Interns and Juniors) did much better with assertive AI.
    They made 39.2% fewer mistakes when using more confident AI guidance.
    They also made decisions faster, about 1.38 times quicker than with regular AI.
    Assertive AI seemed to help them feel sure and less uncertain.
  • Senior Clinicians (Middle and Senior Level) preferred suggestive AI.
    They reduced errors by 5.5% with this style.
    They also decided about 1.37 times faster.
    These senior doctors liked when AI gave suggestions that respected their experience and let them use their own judgment.

Impact on Diagnostic Accuracy and Efficiency

This research shows that matching AI communication to the doctor’s experience can improve accuracy and speed.

  • Reduced Diagnostic Errors: Assertive AI helped juniors avoid many errors but was less helpful for seniors.
    Too much assertiveness might not fit senior doctors who prefer soft advice.
  • Improved Diagnostic Time: Both junior and senior doctors worked faster with AI communication adapted to their level.
    Faster diagnosis helps busy clinics give care quicker and use resources well.

Medical administrators and IT staff should think about AI communication styles when adding AI to healthcare.

Building Trust Through AI Communication

The study found that doctors like AI that is clear and shows it understands the situation.
Doctors want explanations that tell them why, not just numbers.
Trust in AI grows when the AI’s advice matches the doctor’s experience.

Junior doctors need clear, strong guidance to feel confident and accurate.
Senior doctors prefer detailed but gentle suggestions that respect their skills.
Trust is very important for doctors to use AI well.
Without trust, AI might not be used enough or might be used wrongly.

Effects on Clinician Cognitive Workload

Doctors often feel tired and stressed from making many decisions.
Using AI communication that fits their experience can make their job easier.

  • Junior Clinicians benefit from clear, assertive AI that makes decisions simpler and reduces thinking effort.
  • Senior Clinicians like AI that does not overload them with commands but helps them focus on difficult thinking.

Less mental strain improves accuracy and reduces stress.
This also helps hospitals keep their staff happy and working well.

Tailored AI Communication and Workflow Automation in Medical Practices

How AI talks to doctors matters for running hospitals smoothly.
Combining clinical AI with front-office automation, like phone answering systems, can help a lot.

  • Better Decision Support: AI that matches communication styles saves doctors time when reading AI results.
    This helps departments finish more cases faster.
  • Front-Office Phone Automation: Automated phone systems reduce the load on staff so they can focus on medical work.
  • Fewer Interruptions and Errors: When doctors feel less overwhelmed, they make fewer mistakes and get interrupted less.
  • Better Patient Experience: Faster tests and smoother office work mean quicker appointments and results for patients.
    This is important in U.S. healthcare competition.

IT managers and medical leaders should pick AI tools that adjust to doctor experience and help both clinical and office work.

Considerations for U.S. Medical Practice Implementation

When U.S. medical groups add AI to their work, they should think about these points:

  • Expertise-Tailored AI: Use AI that can change how strongly it speaks to fit doctors with different experience levels.
  • Context-Rich Explanations: Avoid AI that only gives unclear or number-based results.
    Choose AI that explains suggestions well to build trust.
  • Training and Education: Help doctors learn when to follow strong AI advice and when to use their own judgment with gentler advice.
  • Workflow Integration: Pick AI that works well with electronic medical records and office automation.
    This reduces disruptions and makes work smoother.
  • Data Transparency and Continuous Improvement: Encourage AI providers to share data and code so hospitals can check and improve AI tools over time.

Case Study Relevance for U.S. Healthcare Settings

The breast cancer imaging study with 52 clinicians represents many U.S. healthcare workers.
Improving diagnosis speed and accuracy matters a lot in busy U.S. clinics.
Knowing that junior and senior doctors have different needs helps hospitals pick better AI systems.

Also, automating simple tasks like phone answering helps doctors focus on patients.
Using AI in both clinical support and office work creates a balanced system for hospitals.

Summary

Studies show that AI communication style affects doctors’ decisions differently depending on their experience.
Junior doctors do better with assertive AI, cutting errors by 39.2% and working faster.
Senior doctors do better with suggestive AI, lowering errors by 5.5%.

Personalizing AI communication builds trust, reduces mental effort, and improves diagnosis speed without losing accuracy.
Medical managers in the U.S. should use AI tools that change how they communicate based on the doctor using them.

Combining clinical AI with office automation, like phone answering systems, helps clinics work better.
Understanding and using AI that suits doctors’ needs will help improve healthcare in the future.

Frequently Asked Questions

What is the focus of the research on personalized AI communication in breast cancer diagnosis?

The research focuses on how personalized AI communication styles affect diagnostic performance, workload, and trust among clinicians during breast imaging diagnosis, emphasizing the adaptation of communication based on clinicians’ expertise levels.

How does personalized AI communication impact diagnostic time for clinicians of different expertise levels?

Personalized AI communication reduces diagnostic time by a factor of 1.38 for interns and juniors, and by a factor of 1.37 for middle and senior clinicians, demonstrating significant efficiency improvements without compromising accuracy.
