Schnipper J, Roumie C, Cawthon C, et.al. Rationale and Design of the Pharmacist Intervention for Low Literacy in Cardiovascular Disease (PILL-CVD) Study. Circulation: Cardiovascular Quality and Outcomes. 2010; 3: 212-219. http://circoutcomes.ahajournals.org/content/3/2/212.abstract . Accessed August 1, 2014. Background— Medication errors and adverse drug events are common after hospital discharge due to changes in medication regimens, suboptimal discharge instructions, and prolonged time to follow-up. Pharmacist-based interventions may be effective in promoting the safe and effective use of medications, especially among high-risk patients such as those with low health literacy.
