Mobile Geolocation Technology to Improve Multidisciplinary Care of Patients With Ventricular Assist Devices: A Feasibility Study.

We evaluated the feasibility of a mobile phone-based geolocation technology in patients with ventricular assist devices (VAD). We prospectively enrolled VAD patients with a smartphone for 6 months. A proprietary mobile technology platform (Position Health, Reading, MA) was downloaded onto Apple or Android smartphones. When a patient entered an emergency department, the app was activated and a "ping" with patient location and contact information was sent to our VAD team pager. Fifty-four patients were approached, and 21 were enrolled. The primary reason for nonenrollment was lack of smartphone (46%). The technology was active for 3780 patient-days and activated on 4 occasions, all cases in which patients were inside a hospital but not seeking emergency care. When surveyed at 3 and 6 months, 90% and 100% of patients, respectively, reported the app remained active on their phones; 14 of 18 (78%) reported the app was helpful and gave them additional reassurance. Implementing this technology for VAD patients was feasible and accepted by patients and providers, but a larger study is needed to demonstrate an impact on care delivery.
