Overview • Define limited health literacy • Discuss the role of health literacy in health care, outcomes, and disparities • Discuss approaches to improve care for at-risk patients • Outline clinical intervention to improve care for patients with limited health literacy • Study outcomes

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

Overview • Define the scope of limited health literacy • Discuss the role of health literacy in health care, outcomes, and disparities • Discuss approaches to improve care for at-risk patients • Outline clinical intervention to improve care for patients with limited health literacy • 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

Outcomes Associatedwith 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

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 Limited Health 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 - Patient • Fff

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
