Patients Forum, a coalition of organizations representing 150 million
Europeans, and the British, too, are looking at empowerment as a financial
imperative. And we should, too.
Here's the problem: traditional healthcare systems were designed for infectious
disease. Treatment fitting the
disease was prescribed and managed by
professionals while patients complied and were cured or died. That
disease-focused model prevails but cannot sustain treatment of modern chronic
conditions and aging populations
where treatment needs differ, treatment

control over their own lives
and increases their capacity to act on issues that they themselves
define as important.” Heath literacy is

resources are considered tools for empowerment. If we consider
information and services as
tools for empowerment, how would we design them
differently? What if the purpose of Informed Consent was
to empower patient
choice rather than legally protect providers?
five “Es” of Empowerment:
• Education: patients can make informed decisions
about their health if they are able to access all the relevant information, in
an easily understandable format.
• Expertise: patients self-manage their
condition every day so they have a unique expertise on healthcare
to be supported.
• Equality: patients need support
to become equal partners with health professionals in the management of their
• Experience: individual patients work with patient
organizations to represent them, and channel their experience
• Engagement: patients need to be involved in
designing more effective healthcare for all, and in research to
deliver new and
better treatments and services
empowerment is a challenge for professionals, too
the European stakeholders, including health professionals, agreed that a major
barrier to achieving the five Es
is health professionals' attitudes. This is not surprising, and it's
likely the same in the US. Special

A body needs about 500 mg per day. The American Heart Association
recommends not more than 1500 mg per day.
The average American adult consumes
3400 mg per day. The average 4 year old consumes 2500 mg. More than 2300
linked to high blood pressure, hypertension, PMS, and kidney dysfunction. Can
you name it?
It's Na, sodium, soda—salt
If we reduced our average salt intake by 3g per day, strong and
clear scientific evidence says we'd have 60,000 to
120,000 fewer new cases of
heart disease annually, 32,000 to 66,000 fewer strokes and 44,000 to 92,000
deaths from any cause. All segments of the population would benefit,
particularly African Americans, women,
elderly, children. Even if we gradually
reduced salt intake by 1g per day over the next 10 years, that would be
more cost-effective than
using medications to lower blood pressure in all persons with hypertension.
The news release includes a link to a summary of the
The Health Literacy Challenge
The evidence is undeniable. We need to reduce salt intake. But
it's a strident challenge. The American Heart
Association offers some good
infographics advising us to "change our salty ways"; but the advice
is far from simple,
and likely to have limited effect.
your sodium palate. Hardly
plain language. The imperative assumes understanding that a body wants
is used to getting. So if you eat less salt, after a few weeks you lose your
taste for it. And if you feed a
toddler salty food, s/he develops a taste for
enjoying foods with less salt.
That means don't use the salt shaker at the table; but only about 6% of
our total salt intake comes from the shaker. About 75% comes from processed and
prepared foods. The rest is
naturally occurring in almost all foods. So the
message means eat fresh fruit, vegetables and meats. That works
if you can find
fresh food in your neighborhood, can afford to buy it and store it, and have
time and skills to
prepare it. But we average Americans eat at fast food
restaurants 4 to 5 times a week. We favor "The Salty 6":
rolls, cold cuts and cured meats, pizza, canned soup, sandwiches, poultry.
for lower sodium items. This directive assumes you know that salt and
sodium are the same thing and
items means food. Looking for such items
means reading food labels (about 48% say they do), and knowing to add
listed as Na, soda, baking soda, sodium, salt— all salt.
The Numeracy Challenge:
What's a mg?
Sodium content is listed in mg —milligrams or g —grams. This is not informative. Only
scientists talk about grams.
Here's translation: 500 mg, the daily amount of salt a body needs to
function, is 1/4 teaspoon (that's a measuring
spoon, not a spoon to stir tea)
or 3-4 shakes of the shaker. The recommended maximum intake is 1500mg or 3/4
tsp. The FDA wants the food industry to gradually reduce sodium in food
processing and preparation to get our
average daily intake down to 2300 mg,
about 1 tsp. One gram is about 1/5
tsp. Here is a converter
These challenges are part of the reason the FDA is working with
restaurants and food producers to lower the
amount of sodium in the food supply
over the next ten years. You can read the proposed guidelines

person can reduce salt intake even a little is likely to enhance their health.
Accessibility: A Universal Precaution
My dad states his age as older-than-dirt. He's lost all hearing and has a bad
back. He gets around with a walker. It's impossible for him to call the doctor
to report an issue or schedule an appointment. He cannot drive or use public
transportation. A routine office visit—getting dressed, out of the house, into
the car, out of the car, into the office and onto the exam table, and then the
whole process in reverse — each
step is an exhausting physical challenge and an assault on his pride. It's also
exhausting and trying for Mom, his primary caregiver, driver and emotional
compass. A check-up takes most of
a day. Nothing is simple.
Recently, Dad slipped off
the edge of the bed and twisted his knee trying to get up. That led to four 911
calls: one to get him up (and discover he could not stand), and three
"citizen assists" to get
him to the doctor's office, from there to the hospital, and after a night in
the hospital, to get him home and into bed. Thank you, my fellow tax payers.
He's not alone.
About 70 million of us Americans have such access needs that
affect hearing, vision, or mobility and impair capacity to obtain heath
information and services. People
with access needs contend with marked health disparities that may originate
from the most fundamental level
—like inability to schedule an appointment, open a pill bottle, or read the
fine print dosing instruction. Disparities also come from health professionals
and researchers acting on assumption and stereotyping instead of data.
Access: first pre-requisite to health literacy
Access, the capacity to obtain…. information and services,
is the first prerequisite to health literacy. And yet, several reviews report
accessibility is not a topic of health literacy research and scholarly
discussion. Further, access needs
is a missing demographic variable in most national databases.
Case in point: the 2003
National Assessment of Adult Literacy population sample included 30% with
access needs; among them nearly half (48%) were deemed to have below basic
health literacy. This is likely an underestimation since NAAL excluded those "who
could not be interviewed due to cognitive or mental disabilities" and did
not report demographics of those with access needs. A worldwide review of
interventions to improve health literacy reports that research has, for the
most part, followed NAAL's example and intentionally excluded people with
mental or physical disabilities, along with other disadvantaged or
"hard-to-reach" groups. Lumping together and then excluding "the
disabled" from research causes disparities to persist; it's ethically
questionable and alienating.
Reacting to a nurse who obviously assumed that his access needs
indicated a cognitive deficit, Dad retorted, " I've got a little back
problem. I can read."
Integrate accessibility into research, practice, policy
Health literacy standards should include accessibility and
universal design approaches that make healthcare environments and information
products usable to the greatest extent possible by everyone, regardless of
their age, ability, or status in life.
Health literacy research should include accessibility, directly involve
people with access needs, and report access-related demographics. To make the
research process itself accessible to those with access needs, reports, like
other health information, should
be available in multiple formats: standard, large print, Braile, text only
electronic format, audiotape, sign language.
Experts suggest we make
greater use of access-enabling assistive technology to communicate with people
with disabilities. The technologies show how universal design and commitment to
accessibility help us all; email,
voice recognition, captioning, GPS — all were originally designed for
those with access needs.

Health Literacy. Stockholm: European Center for Disease Prevention and Control.
Health literacy (HL) thought leaders on the National Academy of Medicine’s Health Literacy Round Table are calling for a new standard definition of HL. Because there are too many definitions in play and researchers have a tough literacy task just to choose one. And because various experts have come up with too many piggy-back terms that connect specific content to the “central concept”. And since we can’t measure things like “basic information” and “appropriate decisions”.
New definition to include providers’ literacy, context, progress, action
The new definition would first and foremost acknowledge that HL is multidimensional, that is, two sided— including “both sides of the exchange”: literacy skills of individuals’ (patient or family members and “information providers”) on one side, and system demands and complexities on the other. The broadened perspective recognizes that healthcare professionals and other info-providers in insurance, pharmaceuticals and IT, like patients, have literacy skills. Those skills may or may not enable Those-Who-Know to understand what patients are saying or to communicate effectively.
Further, the proposed broadened view acknowledges the role of context — “the demands and complexities” of healthcare delivery and financing systems make it difficult for everyone to participate in and obtain the full benefit of healthcare, health promotion, health protection, and “health coverage” (I think that means insurance).
The new perspective embraces the notion of progress—well, shakes hands, at least. HL is described as a process or a pathway, implying that improvement is possible —although the document never uses those terms, referring instead to process and change. Nonetheless, this is a big step away from old evidence suggesting that adults rarely change their level of functional literacy, and the surprisingly wide acceptance of the inference that HL is a fixed individual trait.
Further, HL “operates” in various settings — healthcare, insurance and pharmaceutical organizations are mentioned. And it operates in various media, not just print.
Finally, the new definition will link decision and action. (Applause!). Another big step from “appropriate decisions” usually interpreted as compliance, to “informed action”, which may be against medical advice and still not indicate a cognitive deficit.
The Perspective, as the document is called, is indeed a welcome and overdue broadening of the dominant view of HL as seen from US academic medical centers. However, essential issues remain. Perhaps unresolved debates explain why a new definition is not proposed, only described by its components.
Health Literacy is multi-dimensional. Social dimension still missing
HL is not simply two sided. Literacy skills may be one dimension that exists on “both sides of the exchange”, but literacy itself is multidimensional. The missing dimension in health literacy as defined in the US, and still in the new perspective, is the social dimension.
Literacy is a social construct. Its meaning and measure are constantly evolving to reflect society. Literacy is different for different jobs, communities, goals, as well as for different genders, ages, cultures, times and places. In the same way, the meaning of health is also multidimensional, socially defined and evolving. Most healthcare decisions are made and acted on —or not— in homes and communities in everyday life, not by appointment in offices and hospitals.
At the intersection of health and literacy, it is not surprising to find a diversity of overlapping, sometimes conflicting, always evolving definitions and measures. Experts did not come up with a bunch of new terms to tie their favorite content to a clear central concept of HL — rather they recognized that the theory of multiple literacies for multiple contexts (financial literacy, computer literacy, Spanish literacy) applies to HL, too. So we have maternal HL, mental HL, oral HL, teen HL, LBGT-HL, health insurance literacy, and many disease literacies.
Alternative: new improved research approaches
Try as we might to make health literacy precise and clinical with biomarkers and specific corrective actions that produce predictable results demonstrated in randomized controlled trials, HL remains a social practice that is complicated, dynamic and messy. To understand and influence HL, the challenge is not to distill its meaning down to something easy to research, but to figure out how to research something messy.

Previously in this space we’ve said health literacy for disease prevention
and health promotion is distinguished from health literacy for disease treatment. The latter is typically operationalized as functional literacy (reading and math) in a clinical setting. In contrast, to improve risk behaviors and conditions that affect their health, individuals, families and groups use interactive and critical health literacy skills. These skill sets are applied mostly at home and in the community. We’ve looked at critical health literacy.
Today we look at interactive health literacy, IHL for short.
As we might expect, research is limited and controversy abounds.
Not much is known about IHL
PubMed lists just 13 articles on “interactive health literacy”, two of them review articles. I found no listings on “interactive health literacy” AND “parent” or “mother”. Most IHL studies have been reported from outside the US.
Canadians Manafo and Wong looked at IHL promotion programs for older adults with chronic disease. They differentiated IHL from functional health literacy by the aim of the intervention (skill development to increase capacity to find information and make personal meaning from it vs. information giving to increase knowledge). They found five studies on IHL for seniors, 1 from Canada, 4 from eastern U.S. All relate to training elders to search for health information online. My understanding of Nutbeam’s model of IHL is that it refers to interpersonal interaction and communication, not interactive (vs. static) information. The reviewed studies are limited by small samples, no comparison groups, non-experimental design, non-comparable measures and outcomes.
The second review, from England, is a concept analysis of critical health literacy. Sykes and colleagues describe critical health literacy as a set of characteristics including effective interaction between service providers and users. Key attributes include social and communication skills, and interpersonal skills. So critical health literacy is seen as “arising from …ability to interact effectively”, that is to navigate services, and to advocate and articulate confidently when communicating with a health professional —IHL. This view looks at the faces of health literacy described by Nutbeam as a hierarchy of skill levels that develop linearly. However,not all scholars agree; and it seems difficult to separate interactive from critical health literacy.
Measures of IHL
Two studies, one from Japan and one from the Netherlands, used the Functional Communicative Critical Health Literacy scale which measures frequency of perceived difficulty with tasks indicative of the three levels. These authors describe IHL as the skills that can be used to participate actively in everyday situations, extract health information and derive meaning from different forms of health communication and apply it to changing circumstances, while critical health literacy refers to ability to exert control over health. Among Japanese patients with diabetes, interactive and critical health literacy, but not functional health literacy, were associated with self-efficacy, the most important factor in behavior change. The Dutch authors conclude that IHL was associated with ability to organize care, interact with healthcare providers and perform selfcare.
Again, in these studies interactive/communicative and critical health literacy skill levels overlap and are difficult to differentiate. Indeed, in psychometric testing, communicative (interactive) and critical health literacy were closely related and findings were reported in two categories: functional vs. communicative and critical health literacy.
Rubin et al describe the Measure of Interactive Health Literacy, a 10-minute telephone-administered “performance measure of an individual’s proclivity to engage in information seeking from health information sources” For more info, see:
Skill levels or categories? All are needed to protect and promote health
Another school of thought — the one I’m in — sees categories of health literacy skills rather than levels. Individuals or groups combine skills from Nutbeam’s three categories in different ways for different tasks and situations. Strength in one skill or skill set can make up for weakness in another. And a family or community member can contribute skills that an individual lacks. That’s how health literacy becomes a community asset.
Through interaction, information that is understood cognitively, is processed socially and personalized to the particular context and circumstance. Interactive health literacy skills combine with functional literacy (reading and math) and critical health literacy skills to empower individuals and communities to use information for health and gain control over its determinants.

SNAPW: Improve these behaviors to prevent chronic disease
Smoking, Nutrition, Alcohol, Physical activity, Weight
To find out which providers can improve health literacy for prevention, Australian researchers completed a systematic review of quantitative studies (What works?) and narrative synthesis of qualitative work (Why? How?). The review covers research published 1985 to 2009, much of which was done by US researchers. The authors focused on “members of the primary care team” —providers working in general and family practice, community health, home nursing, private or public allied health, health education, or information— and evaluated their effectiveness in promoting positive change in health literacy and SNAPW behaviors. The researchers ran into some issues that I’ve come up against in an ongoing scoping review to discover what is known about the impact of mothers’ health literacy on maternal-child health. Health literacy and related concepts are poorly indexed, so it is necessary to search on lots of terms. The Aussies wrestled 4691 papers down to 94. We started with 2600+ and are still wrestling. There are many varied outcome measures. There are 50+ instruments to measure functional heath literacy (reading & math) and none to measure interactive or critical health literacy. Nonetheless, this research report is on my must-read list.
Take Home Messages
1. Health literacy can be improved; 71% of reviewed studies demonstrated improvement in health literacy. (A round of applause for the researchers who published what did not work.) Some interventions improved health literacy (measured as knowledge, skill, attitude, self-efficacy, states of change, motivation, or patient activation) without affecting behaviors. This result supports other findings that knowledge and skill do not necessary translate to health promoting action; people make informed choices to not act on what they know. On the other hand, some interventions resulted in improved behavior (smoking) without affecting health literacy; that supports previous findings that specific knowledge may not be a prerequisite for behavior change. One RCT* found that brief counseling by a physician led to increased patient action, but only those who were referred to group programs demonstrated improvement in diet and weight. I suspect that improvement in one health literacy indicator is insufficient to support behavior change, which likely requires some combination of knowledge and skills and motivations and self-efficacy and social support.
2. Non-physician providers are effective health literacy promoters. Nine of 10 interventions provided by nurses, dietitians, health educators (92%) or multidisciplinary teams (91%) improved health literacy. Compare that to three of nine (33%) interventions provided by physicians.
3. Intensity of the intervention seems to be the difference. One study found the average length of visit with a primary care physician was 8 minutes shorter than the time it takes to deliver smoking cessation counseling. Indeed, time was the barrier to improving health literacy most frequently mentioned mentioned by providers, followed by attitudes and beliefs. Most physician-delivered interventions were brief, one-time encounters. In comparison, interventions delivered by non-medical service providers ranged from 6 hours to 2 years. Limited time in clinical settings may preclude the trusting relationship required to support behavior change.
Conclusion: Moderate to high intensity interventions are needed to address SNAPW behaviors. Production demands in primary care settings (see 30 patients a day) limit physicians to brief interventions that can increase knowledge and motivate patient action but rarely result in improved behaviors.
Call to Action
Clinicians: to improve health literacy for prevention of chronic disease, collaborate with-, refer to- and promote participation in intensive programs led by other health professionals and paraprofessionals.
Health educators, home visitors, community health workers, dietitians, public health nurses, social workers, case managers, parent educators, program directors: collaborate with clinicians to integrate health literacy promotion into your usual activities, organize referral relationships, bridge home and healthcare.

health warnings, and delaying pregnancy seems wise. However…
The advice to women to avoid
pregnancy ignores the context in which they are expected to comply. In El Salvador and

women. Abortion is illegal in all cases in El Salvador, where the teen

all births. Abortion is illegal in
99% of cases in Colombia. In Jamaica, abortion is legal in some cases with the

education in the schools. Sexual violence is prevalent. So women lack the
knowledge, services and power to heed the advice.
Colombia’s health minister explained that
his message to women is a good way to communicate risk. The minister seems to
forget that women do not become pregnant by themselves. No similar messages
have been directed to men. For sure, women who hear the warning will fear
pregnancy and birth defects more than they already do, but left to protect
themselves, this amounts to a “Just say No” campaign. It leaves women
vulnerable to blame for unplanned pregnancy and birth defects in their babies,
and to charges of non-compliance that could be misinterpreted as evidence of
low health literacy.

Seeking effective intervention to improve health literacy in parents, in 2009 leading US health literacy authors recognized the need to expand medical academia’s focus beyond reading difficulties. Clearly, intervention to improve health literacy requires a broadened perspective. Because when the problem is perceived as reading difficulties, intervention can only aim to make information easier to read (been there, done that, for decades now), or increase parents’ reading ability (still no pill for that).
Drawing on research from education, cognitive science and psychology, Michael Wolf, Terry Davis, Rima Rudd and colleagues proposed a research agenda to address what they call parents’ “health learning capacity”. In the seven years since its introduction this added conceptual layer, along with repeated calls for the field to move beyond documenting patients’ and parents’ low literacy, have not changed the direction of research.
Thought leaders described health learning capacity, as “the constellation of cognitive and psychosocial skills from which families must draw to effectively promote, protect and mange health”. In particular, learning capacity includes self-efficacy, listening and speaking, motivation and questioning. This sounds a lot like the World Health Organization’s 1998 definition which Renkert and Nutbeam (2001) adapted to describe maternal health literacy as “the cognitive and social skills which determine the motivation and ability of mothers (parents) to gain access to, understand, and use information in ways that promote and maintain their health and that of their children”.
This health promotion perspective on health literacy was roundly rejected by health literacy researchers in US academic medical centers as too broad, messy and unmeasurable; it “diffuses thinking on the matter”. This may be why the authors presented “health learning capacity” as a new concept related to reading ability in a medical setting, rather than suggest adoption of the established broader health promotion definition.
“Health learning capacity” recognizes reading skill (functional literacy) is insufficient to promote, protect and manage personal and child health. Proponents call for interventions to improve parents’ psychosocial skills (social and communication skills), which Nutbeam called interactive skills. Still, proponents reject the few reported interventions as too broad and continue seeking a single reproducible strategy to remedy the “true cause” of health literacy’s effects on clinical outcomes. But a massively multifactorial capacity like health literacy has no one true cause, and no one true remedy. Rather, to promote parents’ health literacy we need to find the right combination of factors that address a particular family’s complex and dynamic “real life”, not just their ability to communicate with doctors. Further, the randomized controlled trial is still considered the “true path” to the discovering the “true cause”. However, the RCT aims to isolate the effects of a single factor. Where the true cause is a dynamic combination of personal, social and environmental factors, an RTC is likely to prove that no single factor works.
Proponents hoped that the idea of health learning capacity would refocus research on how parents actually obtain process and understand information. Findings would better guide continued simplification of information and services. But reducing barriers for people with low literacy does not improve their health literacy, it only reduces the need for health literacy.
The still missing research question is how parents use information for health. What enables a parent to transform their understanding and decisions into desired actions and outcomes? Part of the answer is what WHO and Nutbeam describe as critical health literacy, the critical thinking used along with functional and social skills to ask questions, set goals, make plans, marshall resources, assess progress toward health and quality of life. The range of health literacy skills: are used together and all are required to protect, promote and manage health. The health learning capacity concept expands thinking from purely functional literacy skills (reading,math) to include interactive (psychosocial) skills, but leaves out the empowering critical skills.
Long term, the proposed research agenda calls for education reforms to train more health literate future generations. This suggestion is at once troubling and easy. Its troubling because it assumes adults’ reading and other cognitive abilities are not modifiable in a clinical setting, which means health literacy cannot be improved — so the only course is to reduce literacy demands in the system, and hope the children grow up to be more skilled. This underestimates and disempowers patients and parents. It implies what is needed for the healthcare system to work is a smarter patient.
The goal of better health education in the schools is easy. All that is needed is the political will. The work is done. Health literacy standards and curricula are already defined. They have been and remain de-funded.
Health literacy as a field is moving away from describing the problem of low health literacy, toward removing barriers to understanding health information and services. Intervention to improve parents’ health literacy and child health outcomes is still hamstrung by focus on parents’ cognitive deficits and the perception that improvement is not possible.

Health literacy refers to a person’s ability to use information and services for health. (More definitions)
Using information for health implies three steps:
1) Understanding, that is, decoding the words
2) Making personal meaning, that is, reflecting on the question: What does this mean for me in my situation with my resources, my family, my beliefs, my values?
3) Acting, that is, making choices and turning those choices into desired actions and health outcomes.
These steps coincide with three steps in problem solving,
1) What do you want? For example, a woman decodes information in Beginnings Pregnancy Guide. She understands smoking can harm an unborn baby.
2) What have you got? She acknowledges that she has a pregnancy, and a smoking habit that she enjoys and that relieves stress. She has a husband who smokes and a mother-in-law who smoked through her pregnancy and has a son who turned out fine. She has a budget already stretched, a friend who’s been after her to quit, and a doctor who’s offered some aids. Through self-reflection and discussion with family, friends, experts she makes personal meaning from the information.
3) What’s Next? She makes a choice (decision) not to act or to take action — some small step that she is willing and able to do now to move toward her chosen outcome — a healthy baby, which she understands requires a smoke-free womb.
It is the action (or inaction) that affects the outcome.
The first two steps in using information for health, and in addressing a health problem, are “all in your head”, a purely cognitive exercise with no health effects.
What’s empowerment got to do with it?
Take another look at Step 3 in using information for health: making choices and turning those choices into desired actions and health outcomes. This is the World Bank’s definition of empowerment. And the “Three-Step Dance” is the process of empowerment described by David Emerald in his book The Power of TED* The Empowerment Dynamic.
Empowerment is the act-ive ingredient in health literacy. Without it, it’s all in your head.
