Evaluating the Effectiveness of the How to Talk to Your Doctor HANDbook Program.

Background: Millions of Americans have low health literacy, potentially leading to a number of issues including medication errors, hospital admissions, unnecessary emergency department visits, skipped screenings and shots, and misinterpretation of treatment plans. People with low health literacy have less knowledge of illness management, less ability to share in decision-making, and poorer self-reported health status. Addressing health literacy is necessary to improve health care quality, reduce costs, and reduce disparities.

Objective: The How to Talk to Your Doctor (HTTTYD) HANDbook Program addresses health literacy among rural participants who have low incomes, with a focus on improving health communication among populations that are medically vulnerable by using the HANDbook tool.

Methods: Participants were recruited from 55 rural counties by county extension agents (CEA) to participate in the 1-hour HTTTYD session. Pre- and post-test surveys were completed. A subset of the sample completed a 3-month follow-up survey.

Key Results: Of the 548 participants who fully completed the survey, a Wilcoxon Signed-Rank Test was performed on 484 of the participants who completed both the pre- and post-test. A statistically significant median increase in overall confidence among the participants from pre- ( = 15.99) to post-test ( = 17.76), ( = 13.454, = .000), was noted. A subset of 166 participants also completed the 3-month follow-up survey. A significant increase in health literacy after participation in the HTTTYD HANDbook program from pre-test to 3-month follow-up was noted; effect sizes ranged from moderate to large.

Conclusion: The HTTTYD HANDbook program meets recommendations for successful health literacy programs; significant positive outcomes demonstrate program effectiveness. HTTTYD HANDbook program delivery in rural communities by CEAs demonstrates access to understudied and often difficult-to-reach populations. .

Plain Language Summary: The How to Talk to Your Doctor HANDbook program delivered by county extension agents in rural communities showed capacity to access understudied and often difficult-to-reach populations. The significant, sustained improvement in health literacy noted among program participants demonstrated program effectiveness among those with low health literacy.
