Motivation

Europe faces major societal & economical challenges due to:

• Net increase in chronic conditions (ageing, environment).

• Demand for better healthcare services (welfare, common

expectations)

Increased hospitalization Costs:

• More frequent & longer hospital stays.

• Sophisticated diagnostic operations, treatments & drugs.

Motivation

Promotion of ICT in healthcare drives cost reduction through:

• Standardization of content, systems & processes leading to:

Simplification of procedures (adoption of best practices).

Reduced manufacturing, operating and procurement costs.

• Telemedicine applications that:

reduce avg. number of hospital visits and

avg. hospitalization time.

Some Issues:

Motivation

• Patients to participate more actively in their health-management

(awareness raising, training for correct use of equipment).

• Medical personnel to admit to practice at distance → delegate

physical contact to telco & sw (requires accountable services &

systems):

Prerequisites:

• unify legislation,

• clarify systems security & availability requirements,

• clarify stakeholder responsibilities (doctors, patients, ICT providers).

Healthwear Project

Healthwear: remote health monitoring of chronic patients using smart

textiles.

• EU Project eTEN-029402 funded by Trans-European Networks

Programme of DG Infso & Media

• Medical Context: Home-based hospitalization, early discharge &

rehabilitation of cardiac & COPD patients.

• No R&D. Based on R&D performed in Wealthy FP6 IST-2001-37778.

Objectives

• To base design and implementation on measurable quality indicators of

telemedicine applications.

• To perform market analysis (customer base, competition)

• To design & evaluate different business models maximizing value in

stakeholder interactions.

• To elaborate on legislative & ethical requirements for trans-European

service deployment.

• To configure and operate pilots guiding commercial deployment.

Advantages

Compared to traditional practice, reduces incurred hospitalization costs.

Compared to other telemedicine services, the combined use of e-textiles

and mobile-communications:

• permits continuous and ubiquitous monitoring of health condition

(mobile comms).

• requires minor explicit user intervention (e-textiles & PPU)

• does not constrain daily activity (e-textiles are wearable)

• facilitates diagnosis through simultaneous utilization of multiple

physiological indicators (e-textiles)

Project Technologies

Sensing Fabrics & Garments (smart wearables)

• monitoring of ECG, EMG and respiration,

• motion recognition in neural rehabilitation

• estimation of certain types of human activity (sitting, lying, walking).

Healthwear Textiles

• Stainless steel wire twisted around a cotton textile yarn.

• Special knitting process permits embedding and arrangement of

sensors & processors in textiles that can even be thrown to the washing

machine.

Project Technologies

Portable Patient Unit Measurements

• ECG, hartrate and QRS duration.

• Respiration through impedance measurements

• Skin temperature

• Position – 3D accelerometer

• Chest strain for measuring respiratory rate

• SpO2 measured by separate device attached to the PPU.

Functional Description

Healthwear Server: The back-end of Healthwear information system

Measurement Monitoring:

• Manages communication with PPU, desktop & laptop clients.

• Prepares collected measurements for storage and presentation.

Notifications and Alarms Generator - generates notifications & alarms

depending on:

• Patient profile (medical record, configurable presets).

• Inference, based on the values of multiple phy indicators.

Presentation of Measurements:

multiple views of available information based on use-case, user and terminal

device (ws/laptop, PDA).
