Teach-back
Formal Definition
A patient education technique in which the clinician asks the patient to explain or demonstrate the information they have just been taught in their own words; used to verify understanding rather than confirm receipt of information; evidence-based method for reducing medication errors, improving adherence, and preventing avoidable readmissions.
How It's Used on the Ward
"Teach-back" or "can you tell me back what I just explained?" — asking patients to repeat instructions back to confirm they actually understood, not just heard.
Example
""I just explained how to take your blood thinner. To make sure I explained it clearly, can you tell me: when will you take it, what foods should you avoid, and what are the warning signs to call us about? [Patient explains correctly.] Exactly right — and here is the written instructions as a backup.""
Clinical Context
Teach-back shifts the burden of clear communication from patient to clinician — you are checking if YOU explained it well, not testing if the patient is smart. Effective phrasing: "I want to make sure I explained this clearly — can you tell me..." (not "Do you understand?"). Teach-back is particularly important for: new diagnoses, new medications, discharge instructions, procedural consent. Patient health literacy: 1 in 3 American adults have limited health literacy; medical terminology is routinely misunderstood. Simplify first: use plain language, avoid jargon. Studies show teach-back reduces 30-day readmissions by up to 30%.
