ALERT FRAMEWORK

INTRODUCTION
A framework which continuously monitors data associated with a patient in a hospital and derives an inference from this data based on certain pre-defined rules and reports the inference to the concerned medical personnel.
Data Stream
Logic Sub System
Configuration Block
Administrator’s GUI
Messaging Subsystem
Resource Handler
Response Handler
ALERT FRAMEWORK
MOTIVATION
• Wide application in many commercial domains (specially in medical field).
• Reduces response time of a medical personnel enormously – automated intimation to the medical personnel about condition and location of a patient on the fly
• Several technologies involved in the design of this project – XML, Java servelets, socket programming, etc.
WORK INVOLVED
• Study of similar work at other places
A Functional Approach to Integrating Database and Expert Systems, by Torei Risch, Reni Reboh, Peter Hart, And Richard Duda.
A Web-Enabled FRAMEWORK for SMART CARD Application in Health Services, by Alvin T.S. Chan, Internet Computing and Electronic Commerce Laboratory, Department of Computing, The Hong Kong Polytechnic University
• Requirements analysis – Get clear with the requirements and feasibility issues
• System Design – Designed the overview• Implementation of the system – Converted
design to code• Deployment – Deployed the working system in
a simulated scenario• Testing – Developed the test cases to validate
the software
WORK INVOLVED (continued)
FEATURES
• Rules that can be changed according to the situation (only by a qualified medical personnel)
<rule><expression>
<parameter>PHResult</parameter><comparisionOperator>lessthan</comparisionOperator><number>7.34</number>
</expression><expression>
<parameter>PCO2Result</parameter><comparisionOperator>greaterthan</comparisionOperator><number>40</number>
</expression><toCall>doctor</toCall><urgency>urgent</urgency>
</rule>
FEATURES
• Continuous and real-time monitoring of patient information
• Extensive use of different configurable messaging modes
• Attempt to make fully configurable system
• The implementation is component based with definite interfaces defined for every component
• Developed using the Java Programming language
• XML has been used for designing the rules
TECHNICAL DETAILS
• We have used a client/server model for messaging the user and also receiving a response
• Java Servlets has been used to design the UI
TECHNICAL DETAILS
• Can be extensively used for patient monitoring system.
• A scalable system
• Extendable to other fields – Weather forecasting, Share value monitoring, etc.
• Loosely coupled and hence scalable to great extent.
USP
FUTURE IMPROVEMENTS
• Though an attempt is made still the system can be made completely configurable
• More messaging modes can be added• Other types of rules (rate of change) can
be added• Generation of graphical alerts to the user.
(Integration with Mobile Heart Center)
