Objectives Strategies are needed to improve medication management among vulnerable populations. We tested the effect of providing illustrated, plain-language medication lists on medication understanding, adherence, and satisfaction among Latino patients with diabetes in a safety net clinic. Study Design Randomized controlled trial. Methods Intervention patients received a PictureRx illustrated medication list that depicted the medication, indication, and dosing instructions, accompanied by plain language bilingual text.

Self-reported adherence and satisfaction were secondary outcomes. Analysis was performed by intention to treat. Results Of 200 enrolled participants, 197 (98.5%) completed follow-up. Most (71%) had not graduated high school, and 59% had low health literacy. Patients randomized to illustrated medication instructions had better overall understanding of their medications (P
