 This study will enroll people admitted to the hospital who have acute coronary syndromes or heart failure. Participants will be randomly assigned to either the pharmacist-delivered program or usual care. Participants assigned to the intervention group will receive a pharmacist-assisted medication review while in the hospital, counseling from a pharmacist at the time of hospital discharge, a low-literacy education tool that details the discharge medications, a follow-up phone call 1 to 4 days after discharge, and additional phone calls as needed. Participants receiving usual care will receive a doctor-assisted medication review and nurse-provided guidance on medication usage at the time of hospital discharge. Approximately 30 days after hospital discharge, study researchers will call all participants to collect information on serious medication errors, health care utilization, and disease-specific quality of life.
