5. 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

6. 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

8. 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

9. Outcomes Associated with Health Literacy Health Outcomes General health status Hospitalization Emergency department use Prostate cancer stage Depression Diabetes control HIV control Mammography Pap smear Pneumococcal immunization Influenza immunization STD screening Cost Behaviors Only Substance abuse Breastfeeding Behavioral problems Adherence to medication* Smoking* Knowledge Only Birth control knowledge Cervical cancer screening Emergency department instructions Asthma knowledge Hypertension knowledge DeWalt, JGIM 2004

11. Recommended Approaches for 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

12. 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

13. Patient Perspective Improve literacy Patient Education Empowerment in the clinical encounter – Ask Me 3

14. Problems Complexity – Health literacy in context Expert Authority Universal rather than targeted approach

17. 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

18. 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

20. Outcomes – Patient Characteristics

21. Outcomes – Health Literacy At-risk for Limited Health Literacy  Physicians were not identifying at-risk patients or using recommended communication practices

22. 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)

23. Outcomes – Patient Reaction  Patient Recommendations Regarding Screening (n= 135)

24. Outcomes - Patient  Fff

25. Outcomes – Business Case

26. 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

27. 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
