Medical intelligence for quality improvement in Service Oriented Architecture

In remote healthcare process, patient monitoring system is used to collect health data at home and in outdoor scenarios to facilitate disease management. Service Oriented Architecture (SOA) is used to build a comfortable web based management system for integrating distributed wireless sensor network (WSN) and internet. This paper proposes SOA based data architecture for healthcare. As a case study, patient data monitoring system is taken for implementation. It is not feasible for the caregiver to monitor, analyze voluminous data continuously and generate alerts. Data from the physiological sensors and the history data about the patient are used for analysis and alert generation. It is observed that the proposed architecture supports efficient information retrieval. The aggregated data in the server are sliced and diced by customized hand coding ETL (Extract Transform and Load) process. OBIEE (oracle business intelligence enterprise edition) tool is used to develop this application. This novel approach demonstrates data analysis subsystem of SOA for pattern identification and alert generation.
