Teach-Back in Clinical Settings

Key Questions

KQ1a: What is the effect of teach-back on patient and provider outcomes?

KQ1b: Does the effect of teach-back vary based on clinical context (eg, hospital discharge, perioperative visit), intervention characteristic (eg, mode, content, interventionist), or patient characteristics (eg, education level, age)?

KQ2: What is the effect of strategies to increase use of teach-back on key implementation outcomes (eg, adoption, penetration, sustainability)?

Participants/population:

KQ1: Adult patients or their caregivers*; clinicians** delivering care to adult patients

KQ2: Health care organizations, clinics, teams, or clinicians; patients with or without their caregivers

*Caregiver includes any non-paid, informal individual providing supportive care

**Clinician is defined as health care provider (ie, MD, APP), pharmacist, psychologist, nurse, licensed clinical social worker, or other professionally trained clinical personnel

Intervention(s)/exposure(s):

KQ1: Single clinical synchronous, bi-directional encounter-based interaction using teach-back* by a clinician; must include demonstration of understanding of medical information or skills by repeating the information back to the clinician with or without demonstration of specific skill or behavior.

KQ2: Implementation strategies employed to improve the uptake or use of teach-back by a clinician.

*Include if labeled as “teach-back” but does not include specific intervention description as outlined above. “Teach-back” must be described as part of the intervention as opposed to a strategy used to evaluate an intervention. “Teach-back” must occur in the context of a real-time human interaction though initial education delivery may be delivered via recorded information.

Comparator(s):

KQ1: Usual care, other types of health education delivered by a clinician to a patient or their caregiver

KQ2: No implementation support, comparison between implementation strategies

Context:

Inpatient ward, outpatient clinics

Any country

Outcome(s):

KQ1: Proximal/intermediate outcomes:

  • Patient or caregiver outcomes (eg, understanding/knowledge, satisfaction, trust, measure of affiliation/relationship with provider, self-efficacy/confidence)
  • Provider outcomes (eg, job satisfaction, burnout)

KQ2: Implementation outcomes such as adoption, reach/penetration, adherence to teach-back/fidelity, sustained use, acceptability, feasibility
