 Patients with CHD were recruited when they arrived for a regular doctors appointment. We measured their health literacy skills, asked questions about how they take their medications, and checked their blood pressure and last cholesterol and diabetes measurements. We then assigned patients to 1 of 4 intervention groups intervention ongoing. The first group is receiving usual care, which includes regular medication instructions printed on the bottle and no reminders to refill medicines. The second group gets monthly postcards reminding them to refill their prescriptions. The third group gets a new medication schedule that shows them, with pictures and figures, how they are supposed to take their medicines each day. The fourth group receives both the postcards and the new medication schedule. We are following patients for 1 year to see which intervention has the greatest impact on their medication compliance, blood pressure, cholesterol, and diabetes measurements. We will also examine whether patients health literacy affects the success of the interventions.
