John Mitchell & Associates (JMA) has a close involvement with
two of the major telemedicine projects in Australia, the South Australian
Telepsychiatry Project and The Queen Elizabeth Hospitals (TQEH)
Renal Dialysis Telemedicine Project.
Firstly, JMA was the evaluator of the South Australian Mental Health
Services (SAMHS) Telepsychiatry Project in 1994, focusing on user
rates and types, cost effectiveness, training, implementation, management
and cost effectiveness issues. Our final report "The Challenge
to Embed Telepsychiatry" emphasised the early successes but
fragile nature of the project. The report was favourably received
and further funds were injected into the network in 1995, enabling
its expansion from three to six sites.
Secondly, JMA has managed TQEHs four-site Renal Telemedicine
Project since June 1994 and now has been re-engaged until July 1996.
In September 1995 we produced a comprehensive evaluation of the
first twelve months of the project, entitled "Establishing
Renal Clinical Telemedicine." This paper draws considerably
on material contained in our two reports.
While telemedicine is very topical at the moment , the two South
Australian projects are among a handful of telemedicine projects
that have survived into their second year. Other telemedicine activities
of some note are the telepsychiatry initiatives of Professor Peter
Yellowlees from Queensland University and the long-standing achievements
of the Tanami network in the Northern Territory.
The evaluation study of the telepsychiatry project identified a
crucial challenge for the SAMHS and the South Australian Health
Commission (SAHC): how to ensure that the significant successes
of the 1994 Telemedicine Pilot Project between Adelaide and Whyalla
would lead to the embedding of telepsychiatry in the SAMHS and the
SAHC.
Telemedicine involves the use of telecommunications technology
for the delivery of health care to remote locations and for other
purposes such as clinical assessment, patient management, staff
training and administration. The particular telecommunications technology
used in this project provided for the transmission of live, two
way videoconferencing, using digital compression. Telepsychiatry
is defined as the application of telemedicine in the mental health
field.
The videoconferencing equipment linked clinicians and other health
workers at Glenside Hospital in Adelaide, Riverland Regional Hospital
(255km from Adelaide) and Mt Gambier Hospital (400km). Although
Whyalla Hospital (400km) was not formally part of this Project,
some evaluation of their use of the facilities is recorded in the
report.
The evaluation focused on the non-clinical aspects
of the pilot such as the types of uses, rate of use, user acceptance,
user friendliness, cost effectiveness, productivity gains, technology
reliability and effectiveness and the use of the facilities for
service delivery and education and training.
The SAMHS received a grant from the Health Commonwealth Network
in 1993 to enable it evaluate the use of telecommunications equipment
for a number of applications including telepsychiatry, that is,
professional psychiatric support for clinical services delivered
over a videoconferencing link, mental health team training and development
and case management reviews.
The objectives of the telepsychiatry project included:
- to design an evaluation process to assess the impact of the
telemedicine health system on performance indicators set out below
- to implement and co-ordinate the evaluation process for clinical
applications and administration and education
- and to analyse the following performance indicators: technical,
economic, usage and acceptance of the system, productivity gains,
service delivery and education and training.
The major theme of the report "The Challenge to Embed Telepsychiatry"
was that the SAMHS Pilot Telemedicine Project had achieved much
in 1994 but the project was in a fragile state after its first six
months of operation. The following achievements were recorded:
- the Log of Uses demonstrated that the facilities were used by
a wide range of health care related bodies for numerous applications,
including clinical consultations, staff training and community
health activities
- a User Survey completed by 77 users gave resounding support
for the medium
- interviews with stakeholders at Glenside, Berri and Mt Gambier
revealed strong support among a range of personnel and staff were
convinced that the medium was effective for a range of clinical,
training and administrative purposes
- the literature review indicated that there were aspects of this
pilot, such as the breadth and quality of mental health applications,
that are of international significance
- the willingness of the emergency section at Glenside Hospital
to use videoconferencing for urgent consultations with the country
mental health teams was a significant breakthrough
- a number of patients were able to stay in their country town
rather than be transferred to Glenside for an assessment, because
of the use of the telemedicine facilities.
Compared to similar telepsychiatry projects undertaken overseas,
the SAMHS project produced outstanding results in its first year.
However, as could be expected in any pilot project, problems and
issues arose that needed addressing in the second stage of the project:
- while many organisations had used the facilities either once
or twice, very few had become regular users
- only four psychiatrists used the facilities more than five times,
and one more than ten, between May and October 1994 and only two
general practitioners have been involved
- it is unclear to the outsider as to how much the SAMHS telemedicine
equipment is meant to be used by psychiatrists, how much it is
to be used by other practitioners in the mental health field and
how much it is to be used by other medical fields
- most users have declined the offer of training
- the videoconferencing equipment at Berri and Mt Gambier was
unreliable and prone to breakdown (this was later replaced)
- legal and ethical problems regarding telepsychiatry needed further
investigation
- if the handful of significant advocates or users of the telemedicine
facilities at each of the three sites was to withdraw from active
participation in the project, the project would flounder .
Cost effectiveness issues were discussed in some depth in the report
and the following are summary points:
- use of telepsychiatry will require additional funding, to account
not only for the equipment and transmission costs and the necessary
administration, but also to account for new services that could
be offered to the many people in country areas presently denied
access to mental health care
- whilst on the basis of current client demand, some savings could
be made by the SAMHS in terms of the reduction in the number of
hospital beds that could be required each year and a reduction
in the number of patients transported by ambulance or the police
(which could be as high as 50% of annual figures), as a result
of assessments conducted using telepsychiatry, telepsychiatry
may also uncover presently unmet needs.
In terms of the stages that any innovative technology-based project
moves through, after six months the telemedicine project was still
dominated by "early adopters" who will always support
a new approach if they can predict benefits will arise. For the
project to survive, it needed to move to the next stage where more
conservative "early majority" users, who like to know
that the risks in using the equipment have been removed and who
can see concrete benefits arising, become involved.
"Early majority" users will only join in if the project
is robust, well resourced and likely to succeed. For the "early
majority" to provide active support, telepsychiatry needed
to be embedded as a normal way of providing mental health care in
the SAMHS.
It needs to be stressed that most projects involving videoconferencing
take at least 2-3 years before usage reaches an optimal level, and
the SAMHS equipment had only been operating for six months when
our evaluation concluded in November 1994.
In summary, the telepsychiatry network was in a vulnerable stage
after its first six months of operation: it needed ongoing funding
support, a clear policy framework, improved equipment and maintenance
arrangements, vigorous promotion and continued strong management
if it was to prosper in its second and subsequent years. We are
pleased to report that our challenging report was well received
and that the telepsychiatry network has prospered in 1995. A Telemedicine
Unit has now been formed within the SAHC for Telepsychiatry: a first
in Australia.
TQEHs Renal Dialysis Telemedicine Project was undertaken
by TQEH Renal Dialysis Unit from May 1994 to June 1995 and included
the installation of telemedicine facilities at its four renal dialysis
centres at Woodville, Wayville (10 km from Woodville), North Adelaide
(8 km) and Port Augusta (300 km). The Unit dialyses a total of 145
patients at these four centres, with each patient normally dialysing
three times per week and attending an outpatients clinic once every
two months. The Unit also cares for 29 patients who dialyse at home.
Funding for the project was provided by the SAHC in November 1993,
a brave initiative given the embryonic state of telemedicine at
that time. TQEHs Senior Staff Nephrologist, Dr. Alex Disney,
was appointed Project Director and John Mitchell, Managing Director
of John Mitchell & Associates, was appointed Project Manager
and Researcher, in June 1994. Registered Nurse Julie Meyer was appointed
Project Officer in October 1994. Dr. Disney, John Mitchell and Julie
Meyer formed the project management team. Psychology graduate Benjamin
Mitchell, also from John Mitchell & Associates, provided research
and training assistance.
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 was undertaken as it was considered that telemedicine
has the potential to address a number of the problems listed above.
The original aims of the project were to assess the feasibility
and cost effectiveness of telemedicine as a means of improving the
quality of patient care. The project also aimed to determine the
need for the further education of dialysis staff and to monitor
dialysis processes and equipment at sites remote from the main dialysis
institution.
These aims were later expanded, based on experience, to include
the development of strategies to accelerate user adoption and to
maximise both the number of users within the Unit and the breadth
of telemedicine applications. A further aim was to assess the value
of desktop videoconferencing for clinical consultations.
The term telemedicine implies the use of telecommunications
to provide health care. The aspect of telemedicine trailed in the
project was the use of videoconferencing. The definition of telemedicine
is discussed in some depth in the final report "Establishing
Renal Clinical Telemedicine".
The final report provides insights into the factors critical for
the successful implementation of telemedicine in its first year.
The report indicates that much planning, effort, co-operation and
an appropriate culture within the Renal Unit were needed to achieve
a high level of acceptance of telemedicine.
The project made a number of international breakthroughs for the
cause of telemedicine and for the SAHC: notably,
the ability to conduct clinical consultations at low bandwidths
(128kbps);
the effective use of state-of-the-art desktop videoconferencing
for clinical consultations;
the use of telemedicine by the full gamut of staff and patients
in a workplace;
and the collection of considerable data related to user adoption
of telemedicine.
The report "Establishing Renal Clinical Telemedicine"
demonstrates that telemedicine is a human activity, not a technological
event, and that the technology is merely the vehicle for enabling
the delivery of health care services. Hence, much of the focus during
the project was on cultural issues such as staff and patients
perceptions and expectations, beliefs and motivation.
Importantly, the project management centred on responding to users
needs; providing a constant flow of information, support and training;
adapting the technology to the workplace; and giving staff and patients
sufficient time to see the benefits of telemedicine to themselves.
This story of negotiation and cultural change is uncomfortable
news for those vendors who expect telemedicine equipment sales to
boom merely because the equipment works. It also signals caution
to those consultants who develop cost benefit analyses for telemedicine
based on fanciful assumptions and projections about adoption rates
and patterns as well as to health care administrators who might
hope that telemedicine is easy to implement.
The report also shows that TQEHs successes with telemedicine
cannot simply be transplanted to every other health care unit either
in TQEH or any other hospital. While TQEH project can provide invaluable
information about critical success factors and about how to introduce
innovative technology, telemedicine projects in other organisations
will need to address challenges similar to those that arose in this
project, but specific to their own organisational context. There
are telemedicine facilities in Australia and overseas that failed
to address these general and specific issues, and now lie idle.
The report locates the TQEH Renal Dialysis Telemedicine Project
within the context of the international evolution of telemedicine,
and more recently, the explosion of activity in this field. The
study demonstrates that the challenges and unresolved issues faced
in the project are similar to those faced elsewhere. The project
demonstrates the need for the SAHC to investigate generic issues
such as legal liability, payment for telemedicine clinical services
and confidentiality of clinical sessions.
The report describes the particular culture of the Renal Unit of
TQEH and the management strategies used to implement telemedicine.
Much effort was required to continually modify what was essentially
boardroom videoconferencing equipment to suit the busy and sometimes
frantic, high pressure context of a dialysis ward.
Key strategies used to introduce telemedicine included:
- addressing staff and patients concerns, particularly about
confidentiality, privacy and the mobility of the equipment;
- conducting awareness raising and induction activities as well
as basic and advanced training;
- consulting users and providing them with adequate information
about the aims of the project;
- developing adequate operational documentation;
- continually modifying the technology;
- promoting the concept;
- and providing feedback from evaluation surveys and research.
The main evaluation instruments used were six surveys, including
one longitudinal study, and numerous interviews, observations, small
group discussion and collection of data regarding actual usage.
A case study was also conducted of the use of the desktop videoconferencing
unit by a physician. As a result, the project has gathered one of
the most comprehensive sets of data in the world on user acceptance
and adoption issues within telemedicine.
The main form of evaluation used during the project was participant
evaluation, conducted by the project managers and designed to provide
up-to-date information for the project management team, for immediate
response.
The formative evaluation reveals the hopes, concerns, impressions,
surprises, disappointments and, ultimately, the acceptance of telemedicine
by the staff and patients. The data emphasise the need for
- a continual dialogue with the users about the projects
goals;
- extensive training and practice in how to use the technology;
- and for modification of the equipment so that it is easy to
move and use, reliable and able to provide quality images in a
private setting.
The staff interviews illustrate the range of telemedicine users,
from the clinician, registrar, clinical nurse consultant and registered
nurse to the pharmacist, dietitian, social worker, nurse educator,
technician and ward clerk. This range was much broader than originally
anticipated and adds considerably to the cost effectiveness of the
facilities.
The case study in the report on the use of the desktop videoconferencing
unit is of international significance, as this technology has only
recently become available and there are few precedents for its use
in the clinical setting.
It was not possible to examine, in any detail, cost effectiveness
issues during the project due to the delayed start of the project
at the final two sites, especially Port Augusta. It was also considered
premature to evaluate the project until it had a minimum consistent
level of use had been achieved, otherwise we would just be evaluating
the early installation issues.
However, the report demonstrates that the facilities are saving
time and expenses for TQEH and patients and it clearly illustrates
the role telemedicine can play in ensuring the quality and effectiveness
of satellite centres not staffed by doctors.
In the long term, the major savings from telemedicine may come
from less obvious benefits such as improving the provision of services
to patients, including dietitian and pharmacist services, so that
the health of dialysis patients does not deteriorate to the point
of requiring hospitalisation. The report also demonstrates that
the cost effectiveness of telemedicine is enhanced by many intangible
benefits such as improved staff development, staff cohesion, faster
decision making and instant diagnosis.
Added to the many lessons already noted above are the following
points.
Videoconferencing technology is still mostly designed for static
boardrooms, where dark glass cabinets are appropriate. The two projects
discussed above have shown that:
- mobility of the units is a serious issue. The units are often
too heavy and cumbersome to move from room to room, despite manufacturers
use of the term "rollabout".
- confidentiality of the patient interview is also a significant
issue. The addition of headsets with headphones and microphones
overcomes most of these issues.
- miniature probe cameras are available and, when placed on a
stand, are a valuable clinical aid
- newer model videoconferencing equipment with cordless keypads
are an asset in the clinical arena. PictureTel, who supplied TQEHs
equipment and the second set of equipment for the telepsychiatry
project, have met this requirement.
- a technology integration firm, such as Network Nomis who were
involved with the two projects discussed, is essential for any
substantial installation beyond one or two sites
- project management requirements for telemedicine implementation
are substantial. We are occasionally surprised by health organisations
who think that the hardest decision in telemedicine is selecting
between different brands of videoconferencing equipment. Others
think that if they ask the technology providers to show staff
how to press the buttons, the equipment will be magically integrated
into the daily operational fabric of the hospital. It isnt
that easy!
JMA has considerable experience with managing the implementation
of videoconferencing in organisations, based on our educational,
psychological and management expertise. Factors we consider influence
the adoption of telemedicine into an organisation, such as TQEH
and the telepsychiatry network, include the following:
- unless the technology 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
TQEH project and the results are discussed in the final report.
In the TQEH project 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 siting 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.
Our research for the TQEH project showed that some of the initial
fears of staff about using the system were due to the mismatch between
the project or organisations goals and the individual users
goals. For example, at different stages of the twelve month project,
some staff were not sure what the aim of the project was, what staff
were expected to use it for and how often staff were expected to
use it. In TQEHs Renal Unit, this lack of congruence was aggravated
by the staff being dispersed over four locations, the shift work
nature of the Unit, and the fact that a number of staff are temporary.
Many of the change management strategies listed above enabled us
to address this mismatch in goals. Most importantly, we developed
feedback loops between the Project Management Team and the staff,
so that staff knew we were taking into account their views. In the
second year of the project, we are negotiating performance agreements
with staff on how, why and how often staff will use the facilities.
Some readers of this section may have hoped that "fast-tracking"
would mean quick short cuts. From our work with the two telemedicine
projects and other related projects, we know that there are necessary
processes that, once followed, enable the project to be fast-tracked,
as follows:
- conducting of needs analysis
- clearly defining aims and objectives
- developing a project plan, a project team and clear roles and
responsibilities
- managing the technology installation and modifications
- regularly consulting with key stakeholders and users to match
project and individuals goals
- developing an operational management system
- conducting structured methodology training
- evaluating the project.
In addition to these generic steps, we know that each project involves
a unique organisational culture and different levels of experience
and acceptance of innovations, so the above processes need to be
tailored to suit the specific context.
In the two telemedicine projects we have discussed above, formative
evaluation consisted of surveys, structured interviews, observations,
and regular reports. This formative evaluation was crucial for:
- providing feedback for everyone involved with the project
- enabling the Project Management Team to measure the achievement
of objectives
- providing formal data on usage patterns and behaviour
- providing objective data to complement subjective data
- highlighting problem areas and evaluating the effectiveness
of interventions designed to overcome them.
As mentioned earlier, telemedicine is essentially a human activity
not a technological event, where users attitudes, beliefs,
skills and knowledge are more important than the technology used.
There is a need to rigorously manage the processes of project planning,
implementation, management and training, but every project involves
a unique organisational culture and special challenges.
