Evaluating the effectiveness of the Smart About Meds (SAM) mobile application among patients discharged from hospital: protocol of a randomised controlled trial.

Introduction: Almost half of patients discharged from hospital are readmitted or return to the emergency department (ED) within 90 days. Non-adherence to medication changes made during hospitalisation and the use of potentially inappropriate medications (PIMs) both contribute to postdischarge adverse events. We developed Smart About Meds (SAM), a patient-centred mobile application that targets medication non-adherence and PIMs use.
