Aim 1: To evaluate the primary care environment's receptivity to secure electronic communication (SEC) for medication reconciliation and design a prototype SEC. We will use qualitative methods to characterize the primary care clinic environment - the physical space and facilities, the workflow, the resources, as well as the knowledge, attitudes and skills of staff and, most importantly, the patients. Specific approaches will include in-depth interviews, direct ethnographic observations, and visualization methods Aim 2. To develop a prototype SEC for medication reconciliation through a participatory design process, involving primary care clinicians, staff and patients working collaboratively with the research team, and to test the usability and acceptability of the prototype SEC among a sample of patients and primary care clinicians.
