Telematic requirements for a mobile and wireless healthcare system derived from enterprise models

Abstract

Abstract-A challenge of current innovation in healthcare processes is to improve the time to treatment. This paper addresses the benefits of telematic services and mobile & wireless devices such as vital sign sensors and head mounted cameras for healthcare processes. It explores the telematic requirements for a distributed healthcare environment of Body Area Networks of the mobile devices which are connected by wireless (public) networks (e.g. GPRS and UMTS) to healthcare centres. Our main contribution is the development of Enterprise models, which are expressed in terms of the Unified Modelling Language, for the purpose of identification and justification of the telematic system requirements. The developed Enterprise models separate organizational modelling concerns such as the separation of medical roles from the agents acting in these roles. This separation enables roles to be dispatched virtually to a point of care without transporting along with all the agents, but it requires support of a telematic system to bridge the distance gap. We validate the proposed models against a trauma team scenario and consequently obtain the telematic system requirements which enable improved time to treatment for emergency services.

Viable Investigations and Real-Time Recitation of Enhanced ECG-Based Cardiac Telemonitoring System for Homecare Applications: A Systematic Evaluation

“…Fully analog systems are either (1) fully integrated amplifiers and transceivers or (2) assembled multichip modules. Although the fully integrated devices demonstrated in the literature 13-15 feature very small size and low power consumption (approximately 2-14 mW), they do not provide digital-signal filtering or bidirectional communications (except for the system described in Widya et al, 14 which can modulate the inductive power link as a carrier signal for communication from the base station to the sensor). 15 In addition, in order to compare the performance and capabilities of the fully analog systems, 16 it would be useful to define a figure of merit as the analog telemetry-efficiency factor.…”

A Reconfigurable, Wearable, Wireless ECG System

“…The signal frequency can reach 200 Hz, so we have selected a 500 Hz sampling frequency, with a resolution of 10 bits. Extension to 12 bits, to fulfill the requirements of telematic emergency services [10], is straight forward by choosing a microcontroller with a 12 bit converter.…”

“…Several solutions have been proposed recently [1]- [7]. Some of them are focused on the interoperability [8]- [10]. As part of the CodeBlue initiative at Harvard University [11] a similar ECG system has been developed.…”
