Introduction
The cost of health care has become a national concern.
Medicare was 35 million for 2003 and 35.4 million for 2004
Health care expenditures in the United States will project to rise to 15.9% of the GDP ($2.6 trillion) by 2010.
Impact of Information Technology
Electronic Patient Records
Remote Patient Monitoring
Integration of wireless communication, networking and information technology
large amount of medical information can be collected to help determine the most effective strategies for treating chronic illness, reducing disability and secondary conditions
improving health outcomes, and reducing the healthcare expenses by more efficient use of clinical resources.
Remote Patient Monitoring
Needs to be part of the overall chronic disease management process.
Requires fully integration of
IT Technologies
wireless communication, sensor platform, networking, and database
Clinical enterprise practice
Explicitly incorporates security and privacy policies to protect the end-to-end communication and access of sensitive medical information.
Monitoring CHF Patients
Provide unobtrusive and persistent monitoring
Weight
Blood pressure
Heart rate
Energy expenditure
Data analysis and feedback
Automated - based on thresholds (i.e. cannot allow rapid weight fluctuation, etc.)
Doctor intervention
Bluetooth Daemon
Communicates with weight scale and blood pressure monitor
SDP (Service Discovery Protocol) and SPP (Serial Port Profile) protocols
Hardware configured to send last measurement automatically after measurement is taken
Communicates with SPINEController through text files
Summary and Future Work
Our system is consistent with the existing clinical enterprise practice, and thus have the capability to scale and become part of the overall patient management process.
Future Work
Full migration to Android
Current Android release has no support for Bluetooth – no external sensors
Android 2.0 will have Bluetooth API
Distributed action recognition
Experiments on obese children
Extension of security models to sensor networking system and integration with application-level security models
