Health Literacy and Patient Engagement
Health literacy is the degree to which individuals can find, understand, and use information to make informed health decisions. Limited health literacy affects approximately one-third of adults and is associated with worse health outcomes, higher healthcare costs, and reduced quality of care. Quality professionals should understand the connection between health literacy and quality and implement strategies to improve patient engagement across all literacy levels.
Understanding Health Literacy
Health literacy goes beyond reading ability. It encompasses the ability to navigate the healthcare system, communicate with providers, understand medical instructions, evaluate health information, and perform mathematical calculations related to health (such as interpreting blood sugar readings or calculating medication doses). Organizational health literacy, a related concept, refers to the degree to which organizations make it easy for people to find, understand, and use information and services. Both individual and organizational health literacy affect healthcare quality.
Impact on Quality Outcomes
Patients with limited health literacy are more likely to have difficulty understanding medication instructions, leading to medication errors. They have higher rates of preventable hospitalizations and emergency department visits. They are less likely to use preventive services such as cancer screenings and immunizations. They have worse management of chronic conditions such as diabetes and heart failure. They report lower satisfaction with their healthcare experiences. These associations persist even after controlling for education, income, and insurance status, suggesting that health literacy is an independent predictor of health outcomes.
Universal Precautions Approach
The Agency for Healthcare Research and Quality (AHRQ) recommends a "universal precautions" approach to health literacy. Rather than trying to identify which patients have limited literacy (which can be stigmatizing and unreliable), organizations should assume that all patients may have difficulty understanding health information and simplify communication for everyone. This approach benefits all patients, not just those with limited literacy, because even highly literate individuals can struggle with complex medical information when they are stressed or ill.
Communication Strategies
Effective communication strategies include using plain language (avoiding jargon and technical terms), limiting the amount of information given at one time, using the teach-back method (asking patients to explain in their own words what they understood), providing written materials at a 5th to 6th grade reading level, and using visual aids such as pictures, diagrams, and videos. When developing patient education materials, use clear headings, short sentences, active voice, and ample white space. Have materials reviewed by members of the target audience before widespread distribution.
Organizational Strategies
Organizations can improve health literacy through system-level changes. Simplify forms, instructions, and navigation within the facility. Use interpreter services for patients with limited English proficiency. Design patient portals and digital health tools with usability in mind. Train staff across all departments in health literacy principles. Include patients with diverse literacy levels in quality improvement teams. Measure and monitor health literacy-related quality indicators, such as comprehension of discharge instructions and medication adherence rates. Quality professionals can champion these efforts as part of a broader patient-centered quality strategy.
