Pilot study provides diabetic patients and caregivers with high-tech approach to monitoring and care
Jan 23, 2007
Wilfrid Laurier University and the Toronto Rehabilitation Institute began this week to evaluate the use and impact of a GPS-supported monitoring and alerting system to track diabetic patients’ daily life events and health conditions. This pilot system provides an automated and accurate monitoring of a person’s daily activities, travel and exercise.
Led by Sean Doherty, associate professor of geography and environmental studies at Laurier, and Paul Oh, MD, from the Toronto Rehabilitation Institute, the pilot project is supported by a grant from the Canadian Institutes of Health Research (CIHR) and The Health Technology Exchange (HTX), as well as the expertise of several key technology partners: Research In Motion (RIM), the makers of BlackBerry®, Standard Register’s ExpeData®, Life:WIRE™, Medtronic and TELUS. The system uses commonly available GPS-enabled handsets, secure wireless technologies and a specially developed software application that aggregates all the data into meaningful information for the physician.
“We all know that exercise, heart rate and diet are important factors in successful management of a diabetic patient’s condition,” said Oh. “We anticipate that this GPS-supported monitoring and alerting system will place greater control of health management in the hands of the patient. At a minimum, it will allow individuals to gain a greater appreciation of the effects their work, travel, recreation and eating habits have on their health.”
Approximately 50 patients are expected to participate in the 90-day trial, which will involve monitoring each patient’s daily activities over a three-day period.
“The heart of the system is the software application, which takes a trace of a patient’s GPS location co-ordinates at regular intervals as input, and then provides as output a detailed and highly accurate report of the patient’s activities and trips by start/end time, activity location, mode of travel, environment and other attributes,” said Doherty. “This essentially adds key ‘when’ and ‘what’ attributes to the existing ‘where’ capabilities of GPS technology, with minimal burden to the respondent.”
When combined with physiological monitoring – blood glucose, heart rate and food intake – the system provides an opportunity to assess the impacts of spatial-temporal daily behaviours on health. Web-based retrospective analysis tools for patients and caregivers have also been developed, including automatically generated activity/exercise/food diaries and interactive maps.
The system combines multiple technologies to provide a comprehensive, yet easy-to-use, automated patient data collection solution which requires very little input from the patient:
- Medtronic’s Continuous Glucose Monitoring System (CGMS), a sensor and monitor that logs blood glucose levels every five minutes for up to 72 hours.
- Bluetooth®-enabled heart rate monitor and 3-axis accelerometer communicates directly to a BlackBerry handset.
- Standard Register’s ExpeData Digital Writing Solution captures handwritten dietary logs with a digital pen and transfers the information to a Bluetooth-enabled BlackBerry handset.
- Life:WIRE’s interactive application allows for remote notifications to gather and analyze data and present results via the mobile device or Web interface.
- BlackBerry handsets provide GPS location information and securely transmit all the data over the TELUS network.
The low participant burden with this system, combined with the accuracy of Web-based reporting and wide availability of GPS-enabled BlackBerry handsets, are expected to make this monitoring and alerting system widely accessible and acceptable for a variety of future healthcare applications.
