According to the Agency for Healthcare Quality (AHRQ), the percentage of adults whose healthcare providers always initiated the “teach-back” method increased from about 24% in 2011 to 30% in 2015. Teach-back, an evidence-based way of confirming understanding, begins when providers ask patients to describe in their own words what their providers just told them.
