A distributed approach to Complex Event Processing in RFID-enabled hospitals

Abstract

In this article we adopt the Complex Event Processing (CEP) approach for the management of information related to patients status in the context of RFID-enabled hospitals. Our main objective is to support clinical risk management by combining data from different RFID-based appliances used to monitor patient identification, patient tracking and drugs administration control. We propose a distributed system that directly embodies essential CEP principles such as event abstraction, event aggregation and event transformation to offer a hierarchical and distributed architecture where CEP capabilities are supplied by processing nodes. Events flowing through the system levels are progressively aggregated and refined in order to produce a global scoped information. In addition, we introduce specific events patterns aimed at identifying possible dangerous patient conditions.

A Review on Complex Event Processing in RFID System

“…Besides CEP for the Android platform, the authors have proposed LiSEP [27], an integration of CEP engine based in a distributed system comprising a hierarchy of nodes organized in different levels. The research describes a technique based on CEP and RFID technologies to sustain clinical risk management by detecting potential critical conditions on the patient.…”
