E-healthcare and data management services in a cloud

Abstract

E-Healthcare data management is a core issue in a modern hospital. The data generated is enormous due to newer diagnostic techniques. The medical doctors and patients demand a greater life time for medical data records, they require fast data retrieval, and presentation services for Clinical Decision Support Systems (CDSS). The cost on maintaining a data service centre in an average hospital may be substantial both on infrastructure and qualified ICT staff. The availability of large storage capacities and computing resources from Cloud Service Providers (CSP) is seen as an opportunity to save investment by outsourcing information services. Electronic Patient Record (EPR) management is sensitive issue which requires a foolproof security. It is extremely important to develop methods to relieve the clients from problems of security, integrity, availability and cross CSP mobility. We present E-Healthcare models for ubiquitous services for data acquisition archiving and presentation in Cloud. The management issues and security concerns in cloud domains are addressed by a services architecture proposed. The model includes Wireless Sensor Networks besides communication and storage systems for a typical hospital taking advantage of the Cloud Services Architecture (CSA).
