The period following hospital discharge is a vulnerable time for many patients. Patients are often confused about what to do when they return home from the hospital. Many patients don't take their medications correctly, or they don't take them at all. Patients with poor literacy skills have more trouble than others, because it is harder for them to follow written instructions. Overall, about half of the adults in the U.S. have poor literacy skills. It is important to develop ways to help these adults manage their health better.
