The Wound Care Documentation Project at municipal
elder care

• Agentcities Information Day 3
• Barcelona, February 6-8, 2003
• Hans Kyhlbäck
• Blekinge Institute of Technology
• SWEDEN

Purpose of the Wound Care Documentation Project

• First, with a peer-to-peer system give the
  information owners, i.e. the responsible nurses,
  a decentralised control of wound care treatment
  information
• Second, develop a Graphical User Interface that
  visualize the progress of the wound-healing
  process

3
Municipal health care and wound treatment

• Wound Care treatment is one difficult task out of
  many others
• It is time consuming and takes a lot of patience
  in order to provide successful treatment
• It is percieved that learning and documentation
  might be improved by use of digital images

Today - Vision

• Information is stored in binders

• Information is stored in a distributed network

Members of the Large project, February 2003

The Large project (PAC004, a regular course at
BTH), next step towards our vision

• Field study began and digital images was
  introduced
• First Wound Doc software (HEDVIG) was
  implemented
• Wound Care Documentation (Large project,
  PAC004, spring 2003)
• .......
• .......
• Future use of digital devices such as laptops
  or other handheld computers

13
The Large project will design and implement a
Peer-to-peer system

• Seventeen 3rd year students will work in full
  time during spring 2003
• The Peer-to-peer system will be developed in an
  evolutionary process
• JXTA is the implementation technology

14
The Large project will apply an Interaction
Design method

• Find the vocabulary used in the human work
  practice and adopt it to the software development
  process
• Develop the Graphical User Interface (GUI) in
  cooperation with the end users

15
What data do we share?A preliminary model with
two layers

• 1st layer (personal data and social relations) is
  only shared within the care recipient X Peer
  Group.
• 2nd layer might be shared with all peers in the
  main Peer Group WoundDoc.

16
Authorization layers

• A) personal data, social relations
• B) symptom,
• diagnosis
• C) instructions

Aspects of our p2p network model

• Dynamic creation of subgroups
• Decentralized control
• Data concistency
• Discovery mechanism

18
Dynamic creation of subgroups (1)

• All nodes are parts of the main Peer Group called
  WoundDoc.
• One subgroup per care recipient (cr A, cr B).
  All care recipient groups are created by the
  responsible nurse when s(he) create the care
  recipient.
• A single peer could be a member of several
  different care recipient groups.

19
Dynamic creation of subgroups (2)

• A single peer is able to send messages to all
  other peers within the same Peer Group.
• Peer 2 in this case is a member of both subgroup
  A and B. If s(he), peer 2, sends a message it
  will only be sent to the appropriate subgroup not
  both, e.g. if the message is about care recipient
  A it will be sent to peer 1.

20
The project will be informed by Developmental
Work Research

• Data is gathered in ethnographic studies
• Activity Theory as a theoretical framework
  support analysis and design

21
Artefacts - bandage, etc - digital camera - p2p
network system
Future wound care utilize p2p integrated in the
Activity system
outcome Well treated and the wound successfully
healed
Object Care recipient
Subject a nurse

• Community
• -close relatives,
• - 3, 4 nurses,
• 3 5 assistant nurses,
• doctor

• Rules
• do documentation work,
• respect privacy,
• protect information

• Division of labour
• nurse hands on work, documentation, supervise
  treatment
• assistant nurse make hands on treatment
