Clinician Survey • 16 question email survey • Sent to 411 Wisconsin family physicians • 28% response rate
Impact on Quality and Outcomes >87% Number of Respondents Impact Health Outcomes Impact Quality of Care
Results : Prevalence Mean = 17.4% NALS= 47-51% Number of Responses
Results Does your clinic screen patients?
The Bottom Line • Physicians are aware of literacy impacting on health and health care • They underestimate the extent of the problem
The Impact of Low Literacy on Health • Poorer health knowledge • Poorer health status • More hospitalizations • Higher health care costs
Poorer Health Knowledge Diabetics that know low glucose symptoms 94% 50%
Poorer Health Knowledge Hypertensives that know exercise lowers BP 68% 40%
Poorer Health Status Diabetics with retinopathy 36% 19%
Poorer Health Status • 2923 new Medicare enrollees • Inadequate literacy had increased frequency of: • Diabetes • Hypertension • Heart failure • Arthritis
Poorer Health Status • Medical Outcomes Study (SF-36) • Inadequate literacy had • Decreased: • Physical function • Mental health • Increased • Limitations in activity due to physical health • Pain that interferes with normal work activities
More Hospitalizations 2 year hospitalization rate for patients visiting ED 31% 14%
Increased Health Care Costs Total annual Medicaid charges $10,688 $2,890
Increased Health Care Costs Based on NALS data Majority from increased hospitalizations
Reading Levels • 20% of American adults read at or below the 5th grade level • Most health care materials are written above the 10th grade level.
Low Literacy is Overlooked • Clinicians don’t ask about literacy • Some are not aware of the problem • Not sure how to ask • Not sure how to respond • Do not want to open the can of worms

The Big Secret • % of low literate adults that have not told their:
More likely to have Low Literacy • Older • Immigrants • Less education • Incarceration
More likely to have Low Literacy • Non-white • Low-income • Medical Assistance
