How to Improve Health Literacy in Older Adults

Improving health literacy in older adults requires changes on multiple fronts at once: simpler communication from healthcare providers, better-designed materials, community-level support programs, and digital tools that actually account for aging bodies and minds. The challenge is substantial. A national survey of older adults found that roughly 42% had limited health literacy, with another 20% falling into a marginal category, leaving only about 38% with adequate skills to navigate health information effectively.¹ That means most older adults struggle, to varying degrees, with reading prescription labels, understanding discharge instructions, or evaluating health claims they encounter online. The good news is that researchers have tested a range of interventions, and several produce measurable gains.

Why Older Adults Are Especially Vulnerable

Health literacy tends to decline with age, but age itself is only part of the story. A systematic review of the factors behind poor health literacy in older adults identified a web of overlapping contributors: lower educational attainment, lower income, chronic illness, cognitive impairment, physical inactivity, social isolation, and poor family or social support.² These factors tend to cluster. Someone living alone on a fixed income with multiple chronic conditions faces a steeper hill than someone with a strong social network and financial stability, even if they are the same age.

Sensory decline compounds the problem in ways that are easy to underestimate. In the national survey mentioned above, vision impairment roughly doubled the likelihood of limited health literacy, and hearing impairment raised it by more than 50%.¹ When vision, hearing, and cognitive impairment occur together, the effect on communication is dramatic. One analysis of home care and long-term care recipients found that people with all three impairments were far more likely to have moderate-to-severe difficulty understanding others compared to those with cognitive impairment alone.³ About half of residents with triple impairment had moderate or severe difficulty understanding others, compared to roughly a quarter of those with cognitive impairment by itself.

Hearing loss creates specific problems in clinical settings. Older adults with hearing loss report that medical terminology, noisy environments, and providers who are unaware of their hearing difficulty all contribute to missed information during appointments.⁴ People who lose hearing later in life face additional challenges: reliance on auditory cues that no longer work, environments that amplify background noise, and assistive technologies that don’t always perform well in real-world settings.⁵ The practical implication is that any strategy for improving health literacy in older adults has to account for hearing and vision loss, not treat them as separate issues.

The Teach-Back Method

If there is one technique with the strongest evidence base for improving health understanding in older adults, it is teach-back. The idea is simple: after explaining something, the provider asks the patient to repeat it in their own words. If the patient can’t, the provider explains again differently. This loop continues until the patient demonstrates genuine comprehension.

A study of senior citizens in nursing homes found that a teach-back intervention significantly improved health literacy scores across multiple dimensions compared to a control group receiving standard education.⁶ In a clinical trial with elderly patients undergoing outpatient eye surgery, teach-back led to better understanding of perioperative health knowledge and greater cooperation during the procedure.⁷ Research on hospitalized heart failure patients found it to be remarkably effective for teaching self-care skills, even among patients who were older and lacked independent function.⁸

Despite the evidence, teach-back is strikingly underused. A study that analyzed video recordings of primary care consultations found that physicians asked patients to explain what they were told in their own words in fewer than 4% of visits. Checking whether patients understood the information happened in only about 2.5% of consultations.⁹ In nearly every recorded visit, there was no documentation of a teach-back response at all. The gap between what works and what actually happens in exam rooms is enormous.

Visual Aids and Material Design

Written health materials are the default medium for patient education, but for older adults with limited literacy, a pamphlet full of text can be essentially useless. Visual-based approaches offer a meaningful alternative. A systematic review and meta-analysis found that videos were significantly more effective than traditional text-based methods for helping people comprehend health information. Videos also outperformed written materials alone. Interestingly, videos were not significantly better than oral discussion, suggesting that the human element of having someone talk you through something carries weight comparable to a well-produced video.¹⁰

For materials that do remain text-based, older adults have clear preferences: logical layout, signposted information, larger text, labeled images, and visuals that are relevant to them rather than generic clip art of younger people.¹¹ Pictograms and short videos developed with input from people with low literacy have been shown to improve medication adherence and comprehension.¹² The common thread is that co-designing materials with the intended audience produces better results than creating them in a hospital communications office and hoping they land.

Making Medication Labels Readable

Medication management is one of the most concrete, high-stakes areas where health literacy matters. Older adults take more medications than any other age group, and the labels they rely on are often confusing even for strong readers. Research with older adults and their family caregivers uncovered specific pain points: labels use vague timing language like “twice daily” when “one in the morning, one at night” would be far clearer. Wordy instructions bury the essential action. And the small type size makes labels physically difficult to read for aging eyes.¹³

Participants in that study offered practical advice: use numbers instead of written-out words for quantities, reduce unnecessary phrasing, increase font size, and make instructions direct. As one 77-year-old put it, the label should be “simplified, very direct.” A systematic review of best practices for prescription medication information confirmed these instincts, recommending plain language, typographic cues like bold for key actions, numerical descriptors, and standardized formats.¹⁴ These are not revolutionary changes. They are small, inexpensive design improvements that can reduce medication errors in a population already managing complex regimens.

The Digital Health Divide

Healthcare is moving online fast. Patient portals, telehealth appointments, electronic prescription refills, and health information websites are increasingly the default way people interact with the system. For many older adults, this shift has created a new barrier rather than removing an old one. A scoping review of digital health literacy among older adults found that limited experience with modern technology, combined with declining cognitive and sensory abilities, restricts their capacity to search for, understand, and use online health information.¹⁵

The disparities are concrete and measurable. A cross-sectional survey found that older adults with poor self-rated health were far less able to send messages to their doctors through a portal than those in excellent health. People with mobility restrictions reported lower confidence in finding health resources online. And those living in economically deprived areas were about twice as likely to lack computer access entirely compared to those in wealthier areas.¹⁶ The people who most need accessible health tools are the least likely to be able to use the digital versions of those tools.

Design choices make a real difference here. A systematic review of age-friendly mobile app design identified several features that improve usability for older adults: simplified navigation, enlarged text and touch targets, voice interaction options, and interfaces that tolerate errors gracefully rather than punishing them.¹⁷ Involving older adults in the design process, not just testing the finished product on them, produced substantially better satisfaction and usability outcomes. When patient portals and health apps ignore these principles, they effectively exclude the population that stands to benefit most.

Community Programs and Peer Support

Clinical settings are not the only place where health literacy can be built. Community-based programs that bring education to where older adults already spend time have shown real results. A quasi-experimental study of a community-based participatory health literacy program found that participants in the intervention group were far more likely to engage in health-promoting behaviors like regular exercise and weight management, and were better at navigating health information, compared to a control group.¹⁸ Participants also reported higher health empowerment, the feeling that they could take meaningful action about their own health.

One inventive approach trained Meals on Wheels volunteers to serve as health literacy coaches during their regular delivery visits. Volunteers learned communication techniques and practiced coaching through role-play and video examples. After the training, they were able to carry out literacy-supportive conversations during their existing interactions with homebound older adults, reaching a population that rarely makes it to community health classes.¹⁹ This model of embedding health literacy support into services that already reach isolated older adults is especially promising because it requires no extra effort from the older person.

One important caveat about community programs: gains don’t always stick. A skill-building intervention for rural older adults found that health literacy scores improved immediately after the program but declined over time, suggesting that one-time workshops are not enough.²⁰ Ongoing reinforcement, whether through booster sessions, peer groups, or continued coaching, appears necessary to maintain the benefits.

The Role of Caregivers and Family Members

For many older adults, health literacy improvement is not a solo project. Family caregivers frequently serve as translators, navigators, and advocates, especially as health declines. Patient portals illustrate this dynamic well. Research on how caregivers use portals for older adults near end of life found that family members often gradually take over portal use as the patient becomes less able to manage their own care, using messaging features to communicate with providers on behalf of their loved one.²¹

This makes caregiver-inclusive design important. A review of health literacy and patient web portals identified engaging caregivers and family proxies as one of several key opportunities for improving portal usability among people with limited health literacy.²² In practice, this means portals should allow easy delegation of access to a trusted person, and health education programs should consider training caregivers alongside patients rather than treating the older adult as the only person who needs to understand the information.

Universal Precautions in Healthcare Settings

Rather than trying to identify which patients have low health literacy and adapting only for them, a growing school of thought argues for treating every patient as if they might struggle with health information. The Agency for Healthcare Research and Quality developed a toolkit for this approach, designed to help primary care practices systematically improve communication with all patients. Twelve primary care practices that tested the toolkit found it useful but ran into real-world obstacles: competing demands on staff time, bureaucratic hurdles, limited experience with quality improvement processes, and insufficient leadership support.²³

The development phase of the toolkit revealed that practices gravitated toward tools that were concise and didn’t feel like they required major new resources. Staff buy-in and self-assessment were critical first steps, meaning a practice that skipped the step of honestly evaluating its own communication shortcomings struggled to implement changes.²⁴ The lesson for any healthcare organization is that adopting a universal precautions approach is a long-term cultural shift, not a one-day training. It requires sustained institutional commitment.

Cultural and Linguistic Considerations

Older adults from ethnic and linguistic minority backgrounds face compounded challenges. Language barriers interact with cultural differences in health beliefs, communication styles, and trust in healthcare systems. A review of health promotion strategies for ethnocultural minority older adults recommended collaborative engagement with family, peers, community partners, and health practitioners, along with tools that are culturally and linguistically appropriate rather than simply translated word-for-word from English-language originals.²⁵

The medication label research touched on this too. Older adults with limited English proficiency specifically noted that using numerals instead of written-out numbers and specifying exact times of day rather than using phrases like “twice daily” made labels more accessible regardless of language background.¹³ Small design adjustments that reduce the reading burden can disproportionately help people who are navigating health information in a language they did not grow up speaking.

Teaching Older Adults to Spot Health Misinformation

A growing concern is that older adults are particularly susceptible to health misinformation circulating on social media. Research on older social media users found that many rely on quick mental shortcuts to judge whether health claims are trustworthy, rather than systematically evaluating sources, which makes them vulnerable to emotionally compelling but false content.²⁶

An interview study on how older adults respond to persuasive misinformation revealed a telling split. Some older adults recognized common manipulation tactics, like claims that “big pharma” is hiding a cure, as red flags. Others found the same language emotionally convincing. One participant described how the phrase “big lie” in a dubious health article “hit home” and made the claim seem credible, while another participant said the exact same phrase tripled their skepticism.²⁷ This suggests that health literacy programs for older adults should explicitly teach recognition of common persuasive tactics used in misinformation, rather than just improving reading comprehension. The skill of noticing emotional manipulation in health claims is qualitatively different from the skill of understanding a medication label, and both need attention.

Why the Stakes Are High

The consequences of low health literacy in older adults extend well beyond misunderstanding a pamphlet. Among heart failure patients, limited health literacy significantly increased the risk of hospital readmission within a year. The effect was especially pronounced for older women, who had roughly ten times the odds of readmission compared to women with adequate literacy.²⁸ A separate study of heart attack patients found that those with above-basic literacy had roughly an 18% lower risk of being readmitted within 30 days.²⁹

The financial picture is equally striking. A systematic review confirmed a consistent negative association between health literacy and healthcare costs: lower literacy, higher spending.³⁰ One analysis extrapolated that annual prescription costs potentially attributable to basic or below-basic health literacy could reach around $172 billion nationally, and found that predicted office and emergency room visit expenditures were substantially higher for adults with low literacy than for those with above-basic skills.³¹ These are costs driven partly by preventable emergency visits, medication errors, and hospital readmissions that better communication and comprehension could reduce.

Building Patient Self-Advocacy

One often-overlooked angle is teaching older adults to actively participate in their own safety during medical encounters. A pilot program trained elderly patients to be self-advocates in primary care, educating them about common errors in outpatient settings and giving them specific communication skills to use with their providers.³² The premise is that health literacy is not purely about absorbing information passively. It also involves knowing when to ask a question, feeling entitled to ask it, and having the language to do so. Older adults who grew up in an era when patients were expected to defer to physician authority may need explicit permission and practice to adopt a more active role. Programs that combine knowledge with communication rehearsal address both the informational and the interpersonal sides of health literacy at once.
