Embedded Participant
An embedded participant is a person given a role inside a simulation scenario to help guide it, and the guidance may be positive, negative, neutral, or a deliberate distractor depending on the objectives, the level of the participants, and the scenario. Common roles are a family member, a charge nurse, a consultant on the phone, or a technician, and the person is briefed in advance on what to escalate and what to withhold. SSH now lists embedded participant as a recommended term and has retired confederate.
The terminology change is not cosmetic. The third edition of the Healthcare Simulation Dictionary places confederate in an appendix of terms no longer recommended for use by SSH, and it directs readers to actor, embedded participant, simulated patient, simulated person, or standardized patient instead. Confederate carried a connotation of conspiring against the learner, which cuts against the psychological safety that simulation-based education depends on.
A well-briefed embedded participant is the most flexible instrument in a scenario. They can slow a runaway team, hand a stuck learner one piece of information, add a realistic interruption, or hold back a detail the learner is supposed to ask for, and all of that happens inside the scenario without a voice from the control room breaking the frame.
Poorly briefed, the same role wrecks the session. An embedded participant who improvises, answers questions the scenario meant the learner to reason through, or turns hostile beyond the plan changes what is being assessed and makes performance across learners incomparable. Programs that use the role for assessment write the brief to the same standard they would apply to a standardized patient case, including what the person says when a learner asks something off script.
The role also does emotional work that faculty underestimate. Playing a frightened parent for a run of residents back to back is demanding, and the people who do it well need briefing, breaks, a way to signal distress, and a place in the debrief, in the same way trained standardized patients do.
What this looks like in a program
- Scenario templates carry a separate embedded participant brief listing the role, the cues to give, the trigger for each cue, and the answers to the questions learners most often ask.
- Programs recruit embedded participants from simulation staff and clinical volunteers, and they retire the word confederate from templates and evaluation forms when they bring terminology in line with SSH.
