She has dedicated her research program to making medical information easier for patients and their families to understand. She published the first prospective study demonstrating the effect of limited literacy on mortality in the elderly, and has shown that elders with limited literacy have greater difficulty making medical decisions for informed consent and advance care planning. Dr. Sudore designed and tested an informed consent process for patients with limited literacy and an advance directive that is both literacy and culturally appropriate. Both interventions have been shown to benefit patients — particularly those with literacy and/or language barriers.
