2.Discuss the role of health literacy in health care, outcomes, and disparities

3.Discuss approaches to improve care for at-risk patients

4.Outline clinical intervention to improve care for patients with limited health literacy

Health Literacy Is…“The degree to which individuals have the capacity to obtain, process, and understand basic health infor-mation and services needed to make appropriate health decisions.”-Healthy People 2010

Ability to perform essential health care tasks:

– Understand appointment slips– Follow health instructions– Obtain information about an illness– Participate in discussions of informed consent– Enroll in health insurance plan

Not Simply a “Patient Problem”

• One with implications for quality shared by the provider, healthcare system, and community in partnership with the patient

• Implications for treatment as well as disease prevention/health promotion

Overview1.Define the scope of limited health literacy




5.Study outcomes

Health Literacy Is Needed to Navigate Health “Systems”

• Most patient instructions are written• Verbal instructions

– Often complex– Delivered rapidly– Easy to forget in stressful situation

• Increasingly complex health system– More medications– More tests and procedures– Greater self-care requirements– Participatory/informed decision-making

• Disease prevention/health promotion messages

This is another opportunity (or maybe on the next slide to get them thinking about the HL- HP/DP relationship -- I know you have a section on this but any nuggets you can give to keep their attention so they won't wonder "how/why is this relevant" would be helpful

1.Define the scope of limited health literacy

Recommended Approachesfor Health Care Providers

• Use simple, everyday language• Stick to a 2-3 key points• Draw pictures, write down key instructions

for patients to take home• Effectively solicit questions:

“What questions do you have?”• Ask patients to “teach-back” the main

points to confirm understanding

Problems

• Most clinicians often unaware of patient’s health literacy

• Unable to tailor the clinical encounter to the needs of patients

• Often identified solely as a patient education issue

Patient Perspective

• Improve literacy• Patient Education• Empowerment in the clinical encounter– Ask Me 3

Problems

• Complexity– Health literacy in context

• Expert Authority• Universal rather than targeted approach

Identifying At-Risk Patients A bilingual (English and

Spanish) screening tool that identifies patients at risk for limited health literacy

Developed by Barry Weiss (University of Arizona)

Based on a nutrition label from an ice cream container

Process Patient is given the label Asked 6 questions about how they would

interpret and act on the information Responses are recorded by a clinical staff

member, scored, and entered into the EMR Based on the number of correct responses,

the health care provider can assess the patient’s health literacy level

Outcomes – Patient Characteristics

Outcomes – Health Literacy

At-risk for LimitedHealth Literacy

Physicians were not identifying at-risk patients or using recommended communication practices

Outcomes – Patient Reaction

Patients’ Reactions to Screening Over 95% of patients did not have problems with

screening for health literacy in primary care.

No difference in the reported prevalence of shame (p<0.33) by literacy level (Fisher’s Exact Test)

Outcomes – Patient Reaction Patient Recommendations Regarding

Screening (n= 135)

Outcomes – Business Case

Outcomes – Physician Utilization

Staff training increased awareness of the importance of health literacy and clear health communication

A majority (66.7%) also felt that using the NVS to identify patients with limited health literacy improved their quality of care they were able to deliver

Outcomes – Physician Utilization

Over 60% also felt that scores helped in customizing their communication with patients

Observed tendency to revert back to their normal – pre-intervention – care processes and behaviors
