"Geofencing" Shows Promise in Tracking Chronic Care

Location-tracking apps on smartphones could be used to help track and manage care for thousands of patients who suffer from chronic diseases, and possibly even provide feedback to them on lifestyle changes that could help, according to an initial assessment by researchers at UC San Francisco.

In the study, researchers provided a smartphone app to 3,443 participants age 18 and older from all 50 states. The app, which was developed by app developer Ginger.io in collaboration with study investigators, used “geofencing,” a location-based program that defines geographical boundaries. This app tracked participants when they entered a hospital and triggered a questionnaire when they were located in the hospital for more than four hours.

Researchers found the app alone to be 65 percent accurate in identifying when someone was in a hospital and how long they stayed, which they considered a promising start for a new concept. Their findings appear online March 21, 2017, in the American Heart Association journal Circulation: Cardiovascular Quality and Outcomes.

“As the prevalence of chronic disease increases with the aging population, there is a need for improved health care monitoring and more timely treatment between encounters with health care providers,” said senior author Gregory Marcus, MD, MAS, a UCSF Health cardiologist and director of clinical research in the UCSF Division of Cardiology. “Our app only had moderate accuracy, but this approach could revolutionize not only the way we ascertain if someone is sick, but also could be relevant to geofencing any location for a number of health-care related studies or interventions.”
