Triantafyllidis, A., Koutkias, V.G., Chouvarda, I., Giaglis, G.D., Maglaveras, N. Personal Health Systems for Patient Self-management: Integration in Pervasive Monitoring Environments (2010) LNICST, Springer 55/2010, pp. 87-94
--------------------------------------
Various personal health systems have been applied in pervasive health monitoring, in which the need for patient involvement and self-management support with appropriate health information management tools has been highlighted. This paper presents a novel approach towards constructing a personalized mobile system, introduced as add-on to existing remote monitoring systems, for the management of health information by the patient himself/herself, with a Personal Health Record (PHR) constituting the system backbone. Particular emphasis is given to interconnection aspects with the monitoring system, so as to enable enhanced customization and management of monitoring-driven information provided to the patients according to their requirements/preferences. Communication issues between the monitoring and the proposed system are handled by using well-defined Web service interfaces for data exchange. Our prototype implementation, along with an application scenario presented, illustrate the applicability and virtue of the current work.

4. Patient Self-management: Rationale
Rationale (K.R. Lorig, 2003#): “Whether one is engaging in
a health promoting activity such as exercise or is living
with a chronic disease such as asthma, he or she is
responsible for day-to-day management.”

and mechanisms”, Ann Behav Med., vol. 26, no. 1, pp. 1-7, 2003.

6. Pervasive Monitoring Environments
Problems encountered in Health Information Management
by patients
– Limited User-to-System Interactions
– Tight to the monitoring plan
– Dedicated to the monitoring system functionality
– Variable Context (Time – Location – Activity – Situation):
Inappropriate patient feedback
Limited patient involvement with respect to
customization and filtering of information

8. Target Users & Functionality
• Mobile Personal Health Management System
(PHMS) targeted at Chronic Patients who:
– Use Remote Monitoring Systems (RMSs)
– Are highly aware of their disease
– Wish to engage more actively in their disease management
• Functional Attributes:
– Patient self-reporting
– Configurations related to the value of the Monitoring Output
to the patient
– Monitoring Output presentation preferences

11. Communication Infrastructure
Main Objective: PHMS & RMS Interoperability
• Service-Oriented Architecture (SOA):
– SOAP (Simple Object Access Protocol)
– WSDL (Web Service Description Language)
• Terminology Services:
– UMLSKS (Unified Medical Language System
Knowledge Server)

13. Patient Configuration Capabilities
• MDI Insertion into the PHR
– Whether
• Yes, No and “Send notification” options
– When
• Temporal Exceptions
• Presentation Preferences
– Terminology (medical vocabulary in use)
– MDI detail (e.g. inclusion of the conditions which lead
to the MDI generation)
– Information Access Rights

15. Technical Feasibility
• Integration target:
– Add-on to existing RMS with minimum configurations
• Requirement:
– RMS Web Service Client layer for communication with the PHMS
Integrated & tested with Citizen Health System (CHS)
CHS characteristics:
– Sensor-enhanced RMS with MBU
– System back-end infrastructure based on Component Object
Model (COM) technology
– System-generated feedback
• “Tip” e.g. “Reduce your salt-intake”
