Patient Education and Health Literacy

Chapter 12 Patient Education and Health Literacy

The following excerpts are drawn from reflective journals of students as they learn important lessons about patient education during clinical internships:

Through these excerpts we hear students reflecting on both failures and successes in patient education. How could an understanding of health literacy further inform the practice and teaching effectiveness of these students and of physical therapy clinicians? This is a question we will explore and address in this chapter.

Learning goals

After completing this chapter, the reader will be able to:

1. Describe the scope and breadth of the “literacy problem” in the United States and accurately identify specific patient populations seen in physical therapy who are at risk for low literacy.

2. Define and distinguish between the following terms: general literacy, literacy domains, literacy levels, health literacy, readability, suitability, and comprehension.

3. Discuss risk factors and behavioral cues that might indicate low health literacy in patients and identify appropriate methods for assessing and addressing their literacy needs to achieve desired educational and health-related outcomes.

4. Describe characteristics of effective verbal and nonverbal communication with patients that can create a shame-free clinical environment, facilitate the development of positive relationships, enhance learning, and foster comprehension.

5. Assess the literacy demands, readability, and suitability of written educational materials developed for patients using selected informal methods or formal tools and instruments.

6. Identify or develop home programs, instructional materials, or media resources that are appropriately designed to meet the learning needs and goals of patients and their care providers.

7. Describe and implement several teaching/learning activities that can link classroom instruction about patient education and health literacy with experiential learning in clinical settings.

8. Describe, design, and implement teaching/learning activities that provide opportunities for reflection and dialogue about patient education and health literacy during clinical experiences.

Centrality of patient education to effective clinical practice and achievement of desired health outcomes

Numerous documents directly related to physical therapy practice and education emphasize the centrality and importance of patient education in the everyday work of physical therapists.26 The American Physical Therapy Association (APTA) Guide to Physical Therapy Practice2 identifies patient/client instruction as a key component of intervention in the patient/client management model and defines patient/client related instruction as follows: “The process of informing, educating, or training patients/clients, families, significant others and caregivers is intended to promote and optimize physical therapy services. Instruction may be related to the current condition; specific impairments, functional limitations, or disabilities; plan of care; need for enhanced performance; transition to a different role or setting; risk factors for developing a problem or dysfunction; or need for health, wellness, or fitness programs. Physical therapists are responsible for patient/client related instruction across all settings for all patients/clients.”2(p 47) This definition highlights the depth and breadth of a therapist’s responsibility for effective teaching and promoting learning in clinical encounters in a wide variety of practice settings.

In addition, The Joint Commission standards for accreditation of hospitals and other health care organizations require that individual providers and organizations provide effective, “patient-centered” communications to optimize the quality of care delivered and ensure patient understandings and safety.7 Those standards require, among other things, that education provided to patients is based on assessment of patient and family/caregiver needs (both clinical and communication needs), addresses their needs, is appropriate and adapted to the patient’s level of understanding and abilities, and is delivered using a variety of instructional tools or methods, and that patient comprehension of educational information provided is evaluated. During the past decade, as the standards for patient-provider communication have been further developed and elaborated, The Joint Commission has also spearheaded several initiatives in this area that have culminated in reports that highlight the importance of addressing literacy issues and concerns as health care professionals and organizations serve an increasingly diverse and aging citizenry in the United States.810

Finally, the new Healthy People 202011 (HP 2020) framework and objectives encourage increased emphasis on health communication and the effective use of information technology to achieve the overarching goals of HP 2020. The broad goals of HP 2020 and selected health communication and information technology objectives are shown in Box 12-1.

Selected Health Communication and Health Information Technology Objectives

Clearly, the time for focused attention on the health literacy of the patients, family members, and care providers we encounter in our daily work as physical therapists is here. Furthermore, as our scope of practice continues to expand in the realms of community-based education, health promotion, and wellness, attention to the health literacy of the larger population of individuals in our society is essential for us to be effective health educators. (See also Chapters 13 and 15.)

Scope and magnitude of the “literacy problem” in the united states

Surprisingly, focused attention on general literacy concerns, and more recently health literacy concerns, in the United States is a relatively recent trend in our history. In response to these concerns, however, the first nationwide assessment of adult literacy, the National Adult Literacy Survey (NALS), was conducted by the U.S. Department of Education in 1992. That survey and a 10-year follow-up study, the 2003 National Assessment of Adult Literacy (NAAL), revealed a high prevalence of illiteracy and low literacy in the United States.1214 The NALS and the NAAL defined general literacy as, “Using printed and written information to function in society, to achieve one’s goals, and to develop one’s knowledge and potential.”14

In the 2003 NAAL, the literacy skills of a representative sample of about 20,000 adults (defined as 16 years or older) were measured in three domains. These domains represent three functional tasks that individuals would need to access, understand, and use information (Box 12-2).

In the NAAL, the degrees of difficulty for literacy tasks in these the domains were identified as below basic, basic, intermediate, or proficient. Brief descriptions of these levels and the findings from the 2003 NAAL are shown in Table 12-1. Note that 55% of the sample population was determined to be at the basic or below basic level for quantitative tasks; 43% of the sample population was determined to be at the basic or below basic level for prose tasks; and 34% of the sample population was determined to be at the basic or below basic level for document tasks. If you think about the kinds of tasks patients are required to do in the course of clinical care, those individuals at the basic or below basic level (55% in the quantitative category, 43% in the prose category) might experience significant difficulty completing intake forms, comparing drug plans, identifying what they may or may not drink or eat before a medical test, or following written instructions on prescriptions to determine correct dosages. Even those individuals at the intermediate level (53% in the document category, 44% in the prose category) may have difficulty fully understanding insurance forms and plans, consent forms, and medication and other health care instructions.

In the 2003 NAAL, a health literacy scale was included, and tasks specific to health literacy were assessed nationwide for the first time. The development of this scale and the tasks included in the assessment were guided by a definition of health literacy that had been adopted by the Institute of Medicine15 and used by Healthy People 2010.16 Health Literacy was defined as, “[t]he degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions.”15(p 32) The health literacy tasks in the NAAL were distributed across three domains of health care services or information:

In each of those domains, literacy tasks were identified as primarily prose, document, or quantitative tasks.

The health literacy results of the NAAL were published in 200617 and underscored the need for health care professionals, health care organizations, and the health care system as a whole to “take health literacy seriously.”18,19 The overall findings are shown in Figure 12-1 and indicated that 36% of adults in the sample (representing more than 75 million adults) had basic or below basic levels of health literacy: this means their overall literacy skills were at about an 8th-grade level or below. Of these individuals, 14% were measured at the below basic level and would be considered functionally illiterate when dealing with health information. Fifty-three percent of the individuals in the sample (representing about 114 million adults) were rated in the intermediate level of health literacy (about 10th- to 12th-grade level), and only 12% of the population was considered proficient (see Figure 12-1). Two percent of the individuals in the NAAL sample (representing about 4 million adults) had language barriers that prevented participation and were unable to be measured. Those individuals were categorized as nonliterate in English, although it is important to note that they may be literate in their primary language. The findings also identified several risk factors and populations at risk for low health literacy, and these will be discussed further in the next sections of this chapter.

The good news that emerges from these rather disturbing findings is that there has been increasing attention given to addressing the health literacy problem in the United States, and many initiatives have been undertaken to make health information more accessible, clear, and understandable in all forms (oral, visual, and textual) so that a much larger percentage of the population can evaluate, use, and benefit from the information provided by health care professionals. There is a clear realization that we must not only address health literacy concerns but also move as rapidly as possible toward solutions at the level of individual providers, health care organizations and systems, and health policy makers. This vision and commitment are captured in a summary in the National Action Plan to Improve Health Literacy: “By focusing on health literacy issues and working together, we can improve the accessibility, quality, and safety of health care; reduce costs; and improve the health and quality of life of millions of people in the United States.”20

Implications of low literacy for individual and public health

It is likely that the readers of this chapter are individuals who have at least college-level education and beyond. Think about some of your own encounters in the health care system over the past few years. Have there been times when you were uncertain about or confused by health information provided to you? When, exactly, to take a medication? What food or drink you should avoid before a medical test? How and when, exactly, to do a prescribed activity? Have you ever been befuddled by the language used in various forms you were asked to sign when consenting to care? Or explaining your HIPAA rights? Now, think about individuals trying to understand the complex instructions often given by health care providers or navigating the health care system with substantially lower literacy skills than you have. What might be their understandings—or misunderstandings? Could misunderstandings have serious consequences? What happens if the “signals” they receive from health care providers are confusing or not accurately interpreted as they were intended?

The reader is encouraged to view several videos available on health literacy at the American Medical Association (AMA) website entitled, “Low Health Literacy: You Can’t Tell by Looking” and “Health Literacy and Patient Safety: Help Patients Understand.” An additional video by the Institute of Medicine entitled, “Health Literacy: A Prescription to End Confusion” is available on YouTube. These videos will help students and clinicians gain a clearer sense of the personal experiences of individuals with low literacy skills in our health care system.

There is a large and growing body of literature that suggests links between low literacy and poor health outcomes, but it is beyond the scope or intent of this chapter to review all of that literature. A report from the Agency for Health Care Research and Quality (AHCRQ), however, provides a review of evidence and a summary of the many links between low literacy and poor health outcomes, health status, and health disparities.21,22 What we do know from the literature is that low health literacy can lead to low health knowledge and understanding and thus less healthy behaviors, safety concerns for patients and others involved in their care, disparities in access to and quality of care delivered, and greater health costs for individuals and society. We also know that “literacy skills are a stronger predictor of an individual’s health status than age, income, employment status, educational level, and racial or ethnic group.”23,24 Given the high prevalence of low health literacy skills in our population and the health and societal consequences associated with low literacy, it is incumbent on all health professionals to respond. We must do this in order to address the patient’s right to and need for clear communication about their health, to reduce the potential for error and increase patient safety, to enhance the quality of health care services, and to contain health care costs.

What can we do to be effective communicators and teachers and foster patient learning?

Recognizing populations at risk, risk factors, and health literacy challenges

Based on the findings from the health literacy component of the 2003 NAAL,14,17 we know several groups of individuals are at higher risk for health literacy concerns (Table 12-2).

Table 12-2 Individuals at Higher Risk for Health Literacy Concerns

Population Characteristics
Older adults Adults who are 65 years old or greater had lower average health literacy than those who were younger. The physical changes associated with aging are likely to contribute to or compound this problem—visual changes, hearing loss, cognitive changes, etc. More than 60% of individuals 65 years or older were at the basic or below basic level.
People with low incomes or living at or below the poverty line Adults living at or below the poverty line had lower average health literacy than those above the poverty line.
People with less than a high school degree Average health literacy increases with each higher level of education attained starting with high school graduates or individuals with a GED. Below basic health literacy comprised 49% of adults who had never attended or completed high school.
Racial and ethnic minorities Hispanic adults had lower average health literacy than black, American Indian/Alaska Native, and multiracial adults. Whites and Asian/Pacific Islander adults had higher average health literacy than all of those groups.
Non-native speakers of English Individuals who spoke only English before starting school had higher average health literacy than those who spoke English and another language or only another language before starting school.
Male Gender Men had lower average health literacy than women. Sixteen percent of men were in the below basic category compared with 12% of women.
Persons on Medicare, Medicaid, or uninsured Adults who received Medicare or Medicaid and adults who had no insurance had lower average health literacy than adults who were covered by other types of insurance (employer provided, privately purchased, or military).
Individuals with chronic disease or disability Adults who had chronic disease or disability had lower average health literacy than those who did not.

A quick review of the list in Table 12-2 suggests that many of the individuals we see in our clinics on a daily basis may fall into several of these groups or present with several risk factors for low health literacy concurrently. Being aware of the potential for health literacy concerns is a first step toward responding appropriately but much more is needed. In the following section, we will discuss several strategies and tools clinicians can use for assessing health literacy.

Assessing health literacy: informal assessments

Physical therapists and rehabilitation and health professionals in general are excellent observers. Combined with our recognition of the prevalence of low health literacy in the U.S. population, we can use our keen observational and interviewing skills to identify clues for low literacy or alert us to “red flags.” Picking up on these clues and identifying red flags will allow us to adapt our educational interventions to better meet the needs of our patients. Table 12-3 provides a list of some red flags that you may have encountered in your interactions with patients. Can you identify others?

Table 12-3 Some Clues and Red Flags that Might Suggest Low Health Literacy

  Behaviors You Might Observe Things a Patient Might Say
Reading behaviors Lifts texts closer to face when reading
Points to and follows text with finger while reading
Eyes wander over page without finding central focus
Slow reading; asks someone else to read text/form for them
Signs forms without reading
Struggles with more than one piece of information or paper at a time
May get frustrated with multiple forms, leave the clinic or waiting room
“I forgot (lost, broke) my glasses, can you read this to me?”
“My eyes are tired, I’ll read this when I get home.”
“I’m having trouble seeing.”
“The lighting is not good.”
“I don’t feel well, will you read this for me?”
Self-care behaviors Unable to name medications, explain why they take them or when/how to take them. Identifies medications by color and size of pill, not by name or reading labels
Makes errors or lacks follow-though on self-care instructions such as exercise prescriptions, therapy recommendations, or medication regimens; may appear or be labeled nonadherent/noncompliant
Misses appointments or arrives at the wrong times for appointments
Resists filling out forms or activity logs; forms are incomplete or incorrectly filled out
Waits until illness or problem is advanced before seeking help
“I just put them in my daily/weekly container—I don’t need to know the names of my pills.”
“I lost/can’t find my instruction sheet.” (exercise or activity log)
“Could you just draw pictures of the exercises for me?”
“I lost my appointment card.”
“Could I have my appointments on the same days and at the same time?”
“I was too busy to get help.”
“I don’t have time.”
Communication behaviors Shows signs of nervousness or frustration
May not answer questions or incorrectly answer questions; demonstrates differences between what is heard and read
Is very quiet, passive
Nods head in response to information but doesn’t ask any questions in follow-up
Asks a lot of questions, possibly out of context, about information provided previously or in written materials
In response to questions from the health care provider like “Do you understand?” or “Does that make sense?” always answers “Yes” without further questions
In response to questions like “Do you have any other questions?” frequently answers “No”

Some of the behaviors and responses described in Table 12-3 may be due to many patients with low literacy feeling ashamed about their difficulty reading and trying to hide it—even from family members in some cases.25,26 Because of the potential for shame or stigma, patients may also be hesitant to admit to health professionals that they have difficulty reading or understanding health information. Therefore, we need to develop strategies for assessing and addressing literacy concerns by creating clinical environments and encounters that are “shame free” and reduce the potential for embarrassment or humiliation of the patient.

Therapists can use the social history and the subjective portion of their examination to screen for possible literacy concerns for their patients. For example, as you review information available to you in the medical chart, intake forms, or referrals, be alert for the risk factors identified in Table 12-2. If any of those factors are or may be present, then be on heightened alert for the behaviors listed in Table 12-3. It is also important to remember that stress associated with illness, injury, and disability, in and of itself, can create barriers to communication and understanding of complex health information.

As you conduct the subjective portion of the examination, try to ask questions that would get at the potential for literacy problems while being as nonthreatening as possible to the patient. Some suggestions for questions that may be useful and help to open the door for the patient to discuss their abilities in this realm are shown in Box 12-3.
