QoS Provisioning in Sensor Enabled Telemedicine Networks

? ABSTRACT Enabled by the advances of the wireless sensor network technologies, wireless LANs will play a critical role in providing ubiquitous connectivity for future telemedicine applications. This paper focuses on how to provide QoS over the wireless channel between the Body Sensor Network (BSN) Gateway and the wireless Access Points (AP). Telemedicine applications require […]

Designing Clinical Decision Support Systems in Health Care: A Systemic View

abstract Clinical decision support systems have historically focused on formal clinical reasoning. Most of the systems are rule-based and very few have become fully functional prototypes or commercially viable systems that can be deployed in real situations. The attempts to build large-scale systems without examining the intrinsic systemic nature of the clinical process have resulted […]

Nonparametric Decision Support Systems in Medical Diagnosis: Modeling Pulmonary Embolism

abstract Patients face a multitude of diseases, trauma, and related medical problems that are difficult to diagnose and have large treatment and diagnostic direct costs, including pulmonary embolism (PE), which has mortality rates as high as 10%. Advanced decision-making tools, such as nonparametric neural networks (NN), may improve diagnostic capabilities for these problematic medical conditions. […]

A Cross-Cultural Framework for Evaluation

abstract The evaluation of information systems (ISs), especially in the healthcare field, is a complex task. Evidently, there is a need for better understanding of the different aspects evaluation. While in the general IS science field there have been several attempts to build frameworks and models to better understand the evaluation of ISs, in healthcare […]

BACIIS: Biological and Chemical Information Integration System

abstract Life science Web databases are becoming increasingly essential in conducting everyday biological research. With more than 300 life science Web databases and the growing size of the life science data, searching and managing these complex data requires technology beyond that of traditional database systems. The open research issues include the interoperability of geographically distributed […]

Macroscopic Modeling of Information Flow in an Agent-Based Electronic Health Record System

ABSTRACT This topic presents an architecture, or general framework, for an agent-based electronic health record system (ABEHRS) to provide health information access and retrieval among different medical services facilities. The agent system’s behaviors are analyzed using the simulation approach and the mathematical modeling approach. The key concept promoted by ABEHRS is to allow patient health […]

An Information Technology Architecture for Drug Effectiveness Reporting and Post-Marketing Surveillance

abstract Adverse drug events impose a large cost on the society in terms of lives and health care costs. In this article, we propose an information technology architecture for enabling the monitoring of adverse drug events in an outpatient setting as a part of the post marketing surveillance program. The proposed system architecture enables the […]

Information Retrieval by Semantic Similarity

abstract Semantic Similarity relates to computing the similarity between conceptually similar but not necessarily lexically similar terms. Typically, semantic similarity is computed by mapping terms to an ontology and by examining their relationships in that ontology. We investigate approaches to computing the semantic similarity between natural language terms (using WordNet as the underlying reference ontology) […]

A Distributed Patient Identification Protocol Based on Control Numbers with Semantic Annotation

abstract One important problem of information systems in health care is the localisation and access to electronic patient records across health care institute boundaries, especially in an international setting. The complexity of the problem is increased by the absence of a globally accepted standard for electronic health care records, the absence of unique patient identifiers […]

Image Mining for the Construction of Semantic-Inference Rules and for the Development of Automatic Image Diagnosis Systems

abstract This topic introduces image mining as a method to discover implicit, previously unknown and potentially useful information from digital image and video repositories. It argues that image mining is a special discipline because of the special type of data and therefore, image-mining methods that consider the special data representation and the different aspects of […]
