One of the weakest aspects of most telemedicine programs is
in setting up an organisational and management structure, as well
as an ongoing user- and technical-support program. (Shwartz, 1994)
This chapter provides a description of the project and an overview
of the approach taken to project management.

The plan for TQEH Renal Dialysis Telemedicine Project was
initially prepared by Dr. Timothy Matthew and Dr. Alex Disney
in December 1993 and extended by JMA in May 1994. The document
(see Appendix 1) sets out the aim, background, applications,
costings, projected savings, research framework, the project
team and responsibilities, key dates and milestones.
The project was undertaken by TQEH Renal Unit from May 1994-June
1995 and included the implementation of telemedicine sites
(see diagram opposite) at Woodville, and at satellite centres
at Wayville (10km from Woodville), North Adelaide (8km) and
Port Augusta (300 km).
Funding for the project was provided by the South Australian
Health Commission (SAHC) in November 1993 and the project
officially commenced in June 1994, with TQEH's Senior Staff
Nephrologist, Dr. Alex Disney, as Project Director and John
Mitchell & Associates as Project Managers and Researchers.
(Appendix 2)
The aim of the project was to assess the feasibility and
cost effectiveness of telemedicine as a means of improving
the quality of patient care, further educating dialysis staff
and monitoring dialysis processes and equipment at sites remote
from the main dialysis institution.

Dialysis supports the majority of patients with chronic renal failure.
The number of patients treated is growing at a rate of 10% per year.
75% of patients are supported on haemodialysis and in South Australia
the majority of these are located in satellite centres. The trend
here and overseas is increasing in this direction.
Problems which arise in delivering dialysis in these satellite
units are numerous and include: maintenance of standards of care,
initial training of staff, continuing education of staff and updating
of procedural skills, managing acute problems in patients such as
incidental illness, collapse, fistula problems and maintenance of
professional relationships and discipline in a chronic care situation
remote from senior management and assistance.
These problems are currently managed by high cost options which
involve either staff spending more time gaining a high initial skill
level with regular updating at the parent institution or skilled
personnel travelling to the site (e.g. management, paramedical support,
medical staff). Even with this level of support , compromise is
frequent and in the case of country patients, referral of the patient
back to Adelaide is often necessary.
The project began in 1994 with the expectation that telemedicine,
involving the instantaneous transmission of live two-way video and
audio, could provide a solution to a number of these challenges.
A user needs analysis in relation to the telemedicine project was
undertaken in June 1994. The main issues identified in relation
to the proposed telemedicine project were:
- the major uses of telemedicine within TQEH's Renal Unit's four
dialysis centres were expected to be, in descending order: clinical
diagnosis and patient support, staff development and administration
- clinical applications were expected to include consulting with
patients and handling acute situations
- the major users were expected to be doctors at various levels,
dialysis nursing staff, allied health professionals, machine technicians,
nurse educators and patients
- benefits from the project would be the enhancement of staff
morale and the continuation of the reputations of TQEH and the
Renal Unit for innovation and excellence in health care.
It was recognised that there would be some resistance to the project,
for a number of reasons, including the normal work pressure staff
were under and their lack of experience with telemedicine and therefore
their limited motivation to use the proposed facilities. Hence it
was decided to introduce telemedicine facilities incrementally and
to win staff and patient support gradually, as follows:
- two sites would be established in 1994 and two in 1995: TQEH
Woodville and Wayville in September 1994, Port Augusta in February
1995 and North Adelaide in April 1995
- the initial two sites would be used as test beds for the technology
and for the induction, training and management systems
- room modifications, including lighting and acoustics, would
be tested at the first two sites, before funds were expended at
the other sites
- additional equipment such as document cameras, probe cameras,
headsets and videocassette recorders would be trialed before being
purchased for the last two sites
- the mobility and flexibility of the rollabout units would be
assessed at the first two.
The intention was to embed the process at two sites before extending
it to Port Augusta and North Adelaide. The implementation process
could then be accelerated at the new sites.
The following strategies were used to manage the concerns of the
patients and staff, and to gradually win their support:
- activities to raise awareness were undertaken, acknowledging
the concerns of the users
- the process was promoted through regular memos, newsletters,
one-to-one and small group discussions
- information about project developments, such as the timing of
installations and the provision of training and support, was regularly
made available to the staff and patients
- the results of surveys were provided directly to the staff
- the staff were consulted when decisions were needed on issues
that would affect them, such as the sitting of the equipment and
the modification of the rooms
- a structured staff development program was developed, progressing
from awareness raising activities, to induction, basic and advanced
training
- accurate lists were kept of staff and patients who had been
inducted and trained
- a series of demonstrations and special events were arranged
- equipment designed for ease of use was selected.
Literature on change management and technology adoption (e.g. Moore,
1991) cites the importance of identifying and supporting "champion
users" and early adopters, to provide practical demonstrations
of the benefits of using the new technology. Champions are the outstanding
early users, who willingly use the technology, deliberately providing
leadership and example to their colleagues. Following the lead of
the champions are the early adopters: they are the risk takers who
use the technology before it is settled in; they are excited by
the power of the technology; and they are happy to experiment.
The Project Director, Dr. Disney, was the champion user in the
first year of the project, quickly and enthusiastically using the
equipment, for a range of purposes, throughout the project. His
particular use of the desktop unit is reported on in detail in the
chapter 7.
The Project Officer, nurse educator, Julie Meyer, appointed in
October 1994, also used the system extensively, and introduced all
staff and patients to the medium, using a structured training program.
Part of her role was to identify and support early adopters of the
technology.
Other early adopters included a number of the senior nursing staff
who used the system from the early stages for regular meetings and
a number of patients who were keen to use the facilities.
By early 1995, a second wave of users, often termed late adopters,
emerged. The late adopters are happy to use the system after it
has been trialed and found reliable. A number of these late adopters
are profiled in Chapter 6, and included allied health staff, clerical
and technical staff.
By early 1995, the ad hoc users started to be outnumbered by those
staff who preferred to make regular, scheduled uses of the facilities.
When this happened, it was obvious that the process was becoming
part of the daily routine in the workplace.
In summary, the acceptance of the telemedicine technology by a
range of staff took between three and nine months from the installation
in September 1994: an excellent result, given that adoption of new
technology is often much slower and, in this case of renal telemedicine,
there were no precedents in Australia to follow.
One of the reasons for this acceptance of telemedicine was the
care taken in specifying the technology required. Based on the user
needs analysis, it was clear that:
- audio and video must allow easy group discussion
- audio and video quality must enable easy interaction
- patients and staff at each site must be able to clearly see
and hear each other
- it must be easy for the videoconferencing unit and the document
camera to be moved about
- it must be easy to plug in, turn on and start using the equipment.
Detailed equipment specifications were developed, based on these
five points.
It was decided to operate the equipment at the low bandwidth of
128 kbps, in order to ascertain the quality and performance of the
equipment at this very cost effective transmission rate.
The main videoconferencing technology selected for the project
was manufactured by PictureTel, which was on the State Government
list of preferred suppliers and was able to meet all the technical
specifications. PictureTel agreed to provide a desktop unit to facilitate
its evaluation over three months and additional discount on equipment
upgrades.
Initial equipment purchased included:
- four PictureTel System 4000 rollabout units, with 29" monitor,
full duplex audio, IDEC, camera preset positions, auto focusing
camera with pan, tilt, zoom, and other features
- two Panasonic document cameras.
Equipment purchased later included
- headsets
- 3 probe cameras
- 1 videocassette recorder
- five desktop videoconferencing units.
While the PictureTel equipment came with a good reputation for
ease of use and quality of audio, the units purchased were designed
for boardrooms, not clinical settings, so modification of the equipment
was required.
After the initial equipment was purchased, a technology integration
firm, Network Nomis, was engaged to provide technical assistance
and advice. This required an iterative process with the project
management team regarding alternative solutions to the functional
specifications developed for the equipment. Network Nomis was also
required to become familiar with the special issues arising from
the use of videoconferencing in the dialysis centre at TQEH.
These issues were set out for Network Nomis by the Project Management
Team at the start of the project, as follows:
- the videoconferencing unit would be moved to a number of sites
within TQEH dialysis centre, to any point in the main dialysis
room and to nearby rooms.
- the mobility of the videoconferencing unit would be crucial,
taking into account occupational health and safety issues, hence
the unit's cables would need to be sufficiently long.
- the videoconferencing units normally would be placed so that
a staff member at a remote site could easily see as many patients
as possible with little camera movement
- an additional miniature probe camera might be stored in the
videoconferencing unit, for close-ups of patients and equipment
- as the videoconferencing unit would be wheeled from one patient
to the next, provision to attach the keypad to the front of the
unit would be required
- an additional portable microphone, for patients and staff, might
need to be attached to the videoconferencing unit
- lighting and audio conditions would need to be examined
- the use of headphones for privacy would need investigation
- transmission of data from one site to the videoconferencing
screen at another site should be established
- the videoconferencing unit should be positioned close to an
individual patient, to provide personal interaction with staff
at the remote site.
- the videoconferencing unit will need to be positioned in appropriate
rooms and used in conjunction with the document camera, as a teaching
medium, for both group and individual instruction
- advice might be required on the benefits of miniature probe
cameras, lapel microphones, a microphone attached to a stethoscope
and other enhancements that would enable the staff to use videoconferencing
for effective management of acute clinical problems.
- advice would be required on the technical issues arising from
installation of an additional fixed surveillance camera with fixed
lens on a pan and tilt head, to be used for panning back and forth
across the dialysis area
- advice might be needed on multipoint connections.
Network Nomis was required to give special attention to cabling,
power sources, occupational health and safety, audio and lighting
and other engineering issues that might arise.
These fourteen points provide an indication of the challenge to
the Project Management Team caused by attempting to convert boardroom
videoconferencing equipment to the unique setting of a dialysis
ward.
The project managers, John Mitchell & Associates (JMA), had
considerable experience with managing the implementation of videoconferencing
into organisations (Appendix 2), based on their educational, psychological
and management frameworks. Factors the considered influenced the
adoption of a videoconferencing system into an organisation included
the following:
- unless the system is perceived as being easy to use, reliable
and effective, the system will not be used
- unless users are properly inducted and given support and understanding
over their concerns with the equipment, they will not progress
past novice level of use
- unless users are provided with higher order training, adequate
documentation and structures (such as timetables and local support),
they will not progress to become regular users
- unless users can see specific applications that can make their
job easier or enable them to provide improved quality of care
and service to the client, they will not progress to become regular
users
- users will use the system to the extent that it provides positive
advantages for them in a personal and organisational context
- users are more likely to develop into frequent users if they
have specific goals regarding their use of the system.
These beliefs were tested in surveys and interviews during the
project and the results are reported on in chapters 4-7 of this
report.
Induction and training sessions were undertaken in a number of
stages using a variety of techniques, based on the beliefs listed
above.
The initial Training Program for the Renal Unit comprised five
stages:
- Induction, covering the philosophy and objectives of the project;
technology components; booking system; and resources.
- Basic or Novice Training, covering switching the unit on, operating
the keypad and conducting a basic session.
- Training on the Document and Probe Cameras, covering display
of documents, close-ups of patients and using the controls.
- Advanced Operations Training, covering still graphics, presets,
microphones and the videocassette recorder
- Problem Solving Training Program, covering power failures, document
and probe camera problems and microphones.
It was the responsibility of the Project Officer to induct and
train the staff and patients, and to keep detailed records of those
who had been inducted.
It was considered essential by the project managers that quality
documentation should be developed and distributed to the staff and
patients. The following were the main items developed:
- List of Ethical Practices
- Policy and Procedures Manual (draft)
- Operating Instructions
- Dialysis Telemedicine: Key Aspects for Patients
- Dialysis Telemedicine Project News
A number of items were added to the original system and a number
of trials were conducted to improve it. The main developments were:
- trials with lapel microphones, infra-red and wired headsets,
with selection of the latter
- trials with an electronic stethoscope, which was subsequently
discarded
- addition of larger wheels to rollabout systems
- introduction of a stand with a flexible arm for the miniature
probe camera
- investigation of videocassette recorders
- investigation into the addition of handles to the rollabout
units
- investigation into the addition of a ledge for sitting the keypad
on the rollabout.
The project was promoted both internally and externally, to enhance
staff and patient motivation, to provide feedback for the SAHC and
to win support and sponsorship from vendors. Highlights included:
- production of a high quality videotape on the project, subsequently
shown throughout Australia, Europe and the USA
- articles in TQEH, SAHC, metropolitan, country and national print
media
- a report on Channel 7 news in Adelaide
- appearances by project management staff in videoconferencing
seminars in Perth, Melbourne, Canberra, Sydney, Brisbane, Cairns
and Newcastle
- discussions with health care officials in Singapore about collaboration
- discussions with commercial parties interested in collaborative
ventures
- presentations to visitors from overseas.
The project management focus in the second six months of the project
shifted predominantly to evaluation, research and development, while
the Project Officer concentrated on implementing the operational
procedures, such as training, booking procedures, technology maintenance
and fault reporting. The research and evaluation components of the
project are the subject of the remainder of this report.
