Using Location-Based Smartphone Alerts within a System of Care Coordination

We will design and implement a health information technology-enabled system to improve care coordination following an inpatient admission or emergency department visit. The aims of this study are to: 1) Develop a care coordination system in which a novel smartphone app, CHASER (Coordinating Hospital And emergency use with Smartphone-Enabled Reminders), facilitates information transfer and care coordination following inpatient admissions and emergency visits, and; 2) Conduct a feasibility study examining the system’s preliminary impacts and implementation in a care management program for high-risk patients.
