16.1 Health Literacy, Goals, and Teach-Back
Key Takeaways
- Health literacy (CWCN knowledge 050101) is the ability to find, understand, and use wound instructions; it is not the same as years of school or intelligence.
- Write and speak at about a 5th- to 8th-grade level when the content allows, drop unexplained jargon, and pair words with large-print pictures of the actual dressing.
- Teach-back for a wrap is a show-me check: ask the person to demonstrate, then rephrase if the hands are wrong instead of repeating the same sentence louder.
- Patient and caregiver goals (odor, sleep, time, staying out of a facility) may differ from the nurse's closure goal; sequence teaching to the goal that keeps them in the plan.
- Use a qualified interpreter for limited English; a family child is not an interpreter for dressing steps, infection warnings, or consent.
16.1 Health Literacy, Goals, and Teach-Back
Quick Answer: Treat health literacy as a safety skill, not a reading score. Use plain language at about a 5th- to 8th-grade level when you can, drop unexplained jargon, add pictures and large print, and do not finish teaching until the person can show the skill. Teach-back for a compression wrap is "Show me how you'll wrap," not "Do you understand?" The patient's or caregiver's goal (stop the smell, sleep through the night, keep a job) may differ from the nurse's goal (closure). Cognitive, visual, hearing, and language barriers change the method. Use a qualified interpreter, never a family child.

Why health literacy is a wound outcome
Health literacy is the ability to find, understand, and use health information to make decisions and complete tasks. It is not years of school, English fluency, or intelligence. A retired engineer can fail a dressing change if the sheet is written at a graduate-school reading level, printed in 8-point gray type, and handed over while pain is 8 out of 10. The Agency for Healthcare Research and Quality (AHRQ) universal precautions approach assumes anyone can misunderstand on a given day. Pain, fear, a new diagnosis, sedation, and clinic noise all drop literacy in the moment.
For wound care, failed literacy looks like wraps started at the calf so edema is trapped, a foam dressing rinsed and reused "to save money," a heating pad on a numb heel, or antibiotics stopped on day three because the redness "looked better." Those are teaching failures, not character flaws. If the person cannot do the skill in front of you, you have not finished the visit.
Write materials near a 5th- to 8th-grade level when the content allows. Short sentences. One idea per sentence. Everyday words. "Dead tissue" beats "necrotic slough" until you have taught the word and the person uses it. "Swelling" beats "edema" on the first pass. Many public patient-education programs target about a sixth-grade reading level; the 5th- to 8th-grade band is the practical range for home wound sheets. If a concept truly needs a technical term (ankle-brachial index, biofilm), define it in the same sentence the first time it appears.
Plain language, pictures, and large print
Print at 14-point or larger for older adults and anyone with low vision. High contrast: black on white, not gray on cream. Do not rely on color alone ("the red bottle"). Add line drawings or photos of their dressing, not a stock catalog photo of a different product. Circle the two steps that prevent harm. Leave white space. One skill per page if the person is overwhelmed. AHRQ's teach-back module limits a visit to two to four key points and starts with the most important message.
| Instead of this jargon | Say this | Support it with |
|---|---|---|
| Apply a multilayer compression bandage | Wrap from the toes up. The wrap should feel snug, not painful. Stop if the toes turn blue, go numb, or swell more | Photo of the wrap start, then a show-me check |
| Maintain a moist wound healing environment | Keep the wound a little damp with this dressing. Do not let the skin around it stay wet and white | Side-by-side photos of too-wet versus too-dry skin |
| Perform daily skin surveillance | Look at the skin every day, including the heels, tailbone, and between the buttocks | Body map with check boxes |
| Adhere to offloading | Keep your weight off the sore. Wear the boot whenever you stand or walk, including trips to the bathroom | Photo of the boot on versus the boot in a closet |
Avoid stacked instructions: "Cleanse, debride loosely adherent slough if tolerated, apply a silver foam if exudate is moderate, then a secondary wrap, and call for erythema spreading more than 2 cm." Chunk it. Two to four points today. The rest waits until the hands are safe.
Goals of the patient and caregiver may not be yours
A wound nurse often ranks closure, infection control, and limb salvage. The person living with the wound may rank odor so a spouse will share the bed, drainage so clothes stay clean, pain so sleep returns, or time—a daughter who works nights cannot pack a wound twice a day. If you teach only toward closure, they will nod and then do the plan that matches their life.
Ask, "What would make this week a success for you?" If odor is the crisis, lead with more frequent changes, a cover dressing they can actually obtain, or odor-control steps, then fold in the closure work. Document both goal sets. Shared decision-making is not abandoning evidence; it is sequencing teaching so the person stays in the plan. A caregiver's goal (keep Mom out of a nursing home) may conflict with the patient's goal (no one looks at my feet). Name the conflict. Teach both people, separately if shame or privacy is the barrier.
Barriers: cognitive, visual, hearing, language
- Cognitive: Dementia, delirium, traumatic brain injury, and sedation shrink working memory. Teach one motor skill. Use the same words every visit. Pair a consistent caregiver. Picture cards in order. Do not give a six-step verbal list and leave.
- Visual: Macular degeneration, diabetic retinopathy, and uncorrected refraction make 10-point handouts useless. Large print, audio instructions, a tactile mark where the wrap starts, and a caregiver who can see the wound. Do not use color-only cues.
- Hearing: Face the person, reduce television noise, confirm hearing-aid batteries, and give a written copy of the same two to four points. Shouting from the doorway while you bag trash is not education.
- Language: Offer a qualified medical interpreter (in person, video, or phone) at no cost. National CLAS Standard 7 says to avoid untrained interpreters and minors. A child must not interpret dressing changes, infection warnings, or consent. Family adults are not a substitute except in a true emergency while you obtain a qualified interpreter. Teach-back still happens—in the preferred language, through the interpreter. Do not hand an English pamphlet and call it done.
Low literacy plus shame is common. People say yes to "Do you understand?" because they do not want to look uneducated. That question is not an assessment.
Teach-back and show-me
Teach-back asks the learner to explain, in their own words, what they need to do. The related show-me method asks them to perform the skill. Wound care is a psychomotor job, so "Show me how you'll wrap" is the test, not a recitation of your script. AHRQ notes that if they parrot your sentence, they may not understand. Frame it as a check on your explanation: "I want to make sure I was clear. Can you show me how you will take this dressing off and put the new one on?"
If the demonstration is wrong, assume your teaching failed. Repeating the same paragraph louder is not a method. Rephrase, draw, demonstrate again, then ask for another show-me. Continue until the skill is correct or you change the plan (home health, a simpler dressing, a daily clinic visit). Document what was demonstrated, who demonstrated it, which language and interpreter were used, and which gaps remain.
Scenario: Rosa and the wrap
Rosa, 78, has a venous leg ulcer. Her daughter Elena, 16, is in the room and speaks Spanish and English. Rosa's preferred language is Spanish. She reads large-print Spanish. The nurse's goal is graduated compression and closure. Rosa's goal is "the smell so my husband will sit near me." Elena offers to "just tell her."
The education plan: obtain a qualified Spanish interpreter; do not use Elena as the interpreter. Use a large-print Spanish picture sheet of this wrap. Lead with odor control and the wrap, because odor is Rosa's goal. After one demonstration, say through the interpreter, "Please show me how you will start the wrap at the toes." Watch the hands. If Rosa starts at the calf, rephrase and point to the photo. Elena may later assist as a caregiver after she has been taught in her own right, but she is not the language bridge for medical content.
