Does hospitalization influence patients' medication adherence and community pharmacists' interventions?

Background: Medication adherence reduces disease morbidity. Data regarding changes in a patient's adherence before and after hospitalization and how this hospitalization influences a pharmacist's interventions are scarce.

Objective: To assess changes in adherence to cardiovascular and respiratory medications in the year preceding and following a hospitalization; explore patients' perceptions about medication adherence and the pharmacist's role; and describe pharmacists' interventions regarding medication adherence.
