An interventional study of Ambient AI trauma coach (visible) and Coach hidden (unassisted control) in Wounds and Injuries, Clinical Decision-Making and Decision Support Systems, Clinical, sponsored by Harvard Medical School (HMS and HSDM). Enrolling by invitation at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-11-10.

The goal of this study is to learn whether real-time decision support from an ambient artificial-intelligence (AI) coach improves how physicians lead simulated trauma resuscitations. The main question it aims to answer is:
- Do participants lead simulated trauma resuscitations better when the coach is visible than when it is hidden?
Researchers will compare each participant's cases with the coach visible to their own cases with the coach hidden.
Participants will:
Blinded attending physicians score each case from a recording.
Participants lead simulated trauma resuscitations by voice as the trauma team leader. A computer simulation plays the patient and the trauma-bay team. The ambient AI coach listens to the simulated bay and shows decision-support cards on a dashboard; it does not speak or change the simulation. Performance is scored by attending physicians blinded to condition.
2,217 studies on the registry are indexed under Wounds and Injuries; 441 are open to participants now.
This study's planned enrollment of 10 is below the median of 70 across 1,424 interventional studies indexed under Wounds and Injuries.

Exclusion Criteria:
- Has never led a trauma resuscitation as team leader
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Simulated trauma cases led without the coach's dashboard.
Within-Participant Difference in Team-Leader Performance Score With the Coach Visible Versus Hidden
Team-leader performance form with 4 items (critical actions and commands; prioritization and timeliness; diagnostic workup; leadership and communication), each scored from 1 to 5 by blinded attending reviewers; higher scores mean better performance. The per-case score is the mean of the 4 items. The outcome is each participant's mean score with the coach visible minus the mean with the coach hidden.
Time frame: During the study cases (within 8 weeks of starting)
Mean Simulation Realism Score on a 4-Item Realism Form
Simulation-realism form with 4 items (clinical trajectory; patient response and findings; team and environment; decision pressure and complexity), each scored from 1 to 5 (higher means more realistic), completed by participants and by attending reviewers.
Time frame: After each study case (within 8 weeks of starting)
Mean Coach Alert-Quality Rating per Item on a 4-Item Form
Coach alert-quality form with 4 items (appropriateness; timing; coverage of clinically important omissions; overall quality), each scored from 1 to 5 by attending reviewers (higher is better).
Time frame: During the study cases (within 8 weeks of starting)
Coach-Experience Rating per Item on a 4-Item Survey
Coach-experience form with 4 statements (effectiveness; decision support; usability; trust and reliance), each rated from 1 (strongly disagree) to 5 (strongly agree), completed by participants after the last study case.
Time frame: After the last study case (within 8 weeks of starting)
