AIDET (Acknowledge, Introduce, Duration, Explanation, Thank You)
AIDET is a five-step framework for how staff talk with patients and families, standing for Acknowledge, Introduce, Duration, Explanation, and Thank You. Studer Group, now part of Huron, created it as a foundational tactic for patient communication and is explicit that keywords matter but AIDET is not a script, so what gets standardized is which elements appear in every encounter rather than the sentences used. The stated aims are lower patient anxiety, better adherence, and better clinical outcomes, and hospitals apply it across nursing, medicine, technicians, environmental services, and food service rather than to physicians alone.

Each letter names something the patient can notice. Acknowledge is greeting the patient and whoever else is in the room before anything else happens. Introduce is your name, your role, and what you are there to do, which carries unusual weight in a teaching hospital where a patient meets residents, fellows, and attendings across one morning and often cannot say who is responsible for their care. Duration is a time estimate, for the procedure or for the wait. Explanation is what happens next and why, in words the patient can repeat. Thank You closes the encounter, frequently by thanking the family for their part in it.
The framework was built for consistency rather than for eloquence, and that is also where teaching it gets hard. A clinician who recites five steps in order sounds like a clinician reciting five steps, so the skill being trained is the judgment underneath: how much duration detail this particular patient needs, whether the explanation actually landed, and when the acknowledgment has to come before the agenda rather than after it. Teach-back sits naturally on top of the E, because it tests whether the explanation worked instead of whether it happened.
There is evidence that the framework trains better through practice than through lecture. Liang and colleagues studied 117 third-year postgraduate residents at Sun Yat-sen University Cancer Center, comparing conventional lecture-based teaching against situational simulation combined with AIDET, both three hours and both delivered by the same instructors, and reported higher SEGUE Framework scores in the simulation arm (22 versus 18, p < 0.001) and higher standardized patient CARE ratings (45 versus 43, p < 0.001). The comparison was simulation plus AIDET against a lecture at a single center, so it does not separate the framework from the teaching method that carried it.
AIDET's institutional pull comes from HCAHPS. The nurse and doctor communication sub-measures each ask how often staff treated the patient with courtesy and respect, listened carefully, and explained things in a way the patient could understand, which is close to what the A and the E ask a clinician to do. That alignment is why AIDET turns up in service excellence programs, and also why it is so often rolled out as an audit checklist. Programs that get more out of it treat the five steps as behaviors a coach can point to in a recording, rather than as boxes a staff member confirms they ticked.
What this looks like in a program
- Asking staff whether they used AIDET produces a completion rate. Scoring a recorded encounter against the five behaviors produces something a coach can work with.
- The Introduce step does the most work in a teaching hospital, where role confusion is the patient's ordinary experience rather than an exception.
- Teach-back is the check on Explanation, so programs that train AIDET without it can confirm the explanation was given and nothing about whether it worked.
