Distance education for health centre staff in rural Japan.

We have evaluated a course delivered by videoconferencing to rural health centre staff in Hokkaido. The course focused on the planning and evaluation of community health interventions. It included four 90 min sessions and two follow-up sessions. Fourteen professional staff members (public health nurses, nutritionists and dental assistants) attended each class. Knowledge of community health-care planning and evaluation was higher at post-education testing than pre-education testing. Ratings for 'using a computer', 'using some computer software', 'using the Internet' and 'interest in telehealth' increased significantly in post-education testing compared with pre-education testing. The course had an additional benefit in increasing the collaboration between community health workers and university staff.

A conference support system for telehealth.

We have developed a system that supports presentations in meetings and conferences. Using computers and a network such as an intranet, it enables users to share conference materials effectively, and manages and delivers them easily. If it is used in conjunction with a videoconferencing system, users can hold a teleconference and participate in presentations from various remote sites. From the viewpoint of information transmission, the requirements for a presentation in a teleconference are similar to those for a remote classroom or lecture. We believe that this conference support system is suitable not only for conferences but also for education and telehealth.

The Centre for Minimal Access Surgery--teaching for tomorrow.

The Centre for Minimal Access Surgery (CMAS) was established as a state-of-the-art multidisciplinary technological education and research centre for minimal access surgical techniques. Up-to-date training models were obtained to facilitate skill acquisition. Among these were the Minimal Access Therapy trainer and the Body Form Simulator, which provide simulations of the human form on which students can practise operative procedures. The CMAS also acquired the MIST Virtual Reality system, a computer program that facilitates the acquisition of laparoscopy skills. Finally, the CMAS compiled a multimedia library of resources. While many skills can be gained in these synthetic and didactic environments, they cannot provide all the preparation necessary to practise competently. To facilitate the realtime observation of surgical procedures and the telementoring process, the CMAS has commissioned the development of an integrated videoconferencing system that permits the high-quality, rapid transfer of multi-feed video and audio data of surgical procedures from an operating room to the classroom.

The role of telenursing in the provision of geriatric outreach services to residential homes in Hong Kong.

A residential nursing home in Hong Kong was linked to the community geriatric assessment team based in a regional hospital using videoconferencing equipment operating at 384 kbit/s. The feasibility of providing nursing services and their acceptability to users were evaluated over 12 months. There were 198 occupants of the nursing home and their mean age was 82 years (range 60-101). Services included patient education regarding the use of a metered dose inhaler, wound management and a falls prevention programme, together with assessment of clients' need for infirmary care and the risk of aspiration. The acceptability of the system to the clients and nursing home staff was also assessed. It was found that 89% of such services could be carried out via telemedicine, and only 11% required on-site visits. There was an increase in the proportion of patients correctly using inhalers as well as a reduction in the number of falls. More consultations were conducted by the nurse (an increase of 76% per month) and an additional 8.4 patients per month could be attended to by the nurse compared with 5 patients when on-site visits were used. Acceptability to clients and nursing home staff was good. The problem of lack of resources to support elderly residential care institutions makes service delivery via telemedicine appear economically attractive, as well as facilitating improvements in the quality of long-term care.

Evaluation of a routine telepsychiatry service.

An assessment was undertaken of a routine telepsychiatry service in rural areas of a Canadian province as a follow-up to a pilot telepsychiatry project. Over two years, there were 546 consultations at the five participating general hospitals, although the level of use varied considerably between them. Health professionals expressed high satisfaction with the service. While there were equipment problems in 17% of all consultations in the second year, they did not seem to affect acceptance of the technique. A cost analysis comparing consultations provided by a visiting psychiatrist and telepsychiatry found a break-even point of 348 consultations a year. However, when use of the videoconferencing network for administrative meetings was considered, the break-even point was 224 consultations a year, substantially below the actual utilization of telepsychiatry. Telepsychiatry appeared to result in increased access to community mental health services, suggesting future increased demand for these. From the perspective of health authorities and health professionals, telepsychiatry proved to be a useful and sustainable addition to existing mental health services.

Neurological teleconsultation for general practitioners.

A neurology teleconsulting network was implemented between a university hospital in Lisbon and five nearby health centres. PCs equipped for videoconferencing were installed, connected by ISDN lines at 128 kbit/s. Fifty-three general practitioners (GPs) were surveyed. The survey showed that the GPs had difficulties in using computers, but they had definite intentions to use teleconsultation for neurology cases and 83% of the respondents stated that they would probably use the technique. During the study, 90 neurology teleconsultations took place over 55 weeks. The average consultation rate was 1.6 teleconsultations per week (SD 1.3, range 0-6). The conferences lasted 10-45 min. Longer teleconsultations were mainly due to technical difficulties in using computers on the part of users with a low level of computer literacy. The patients were 42 males and 46 females, with a mean age of 38 years (SD 20, range 1-84); two patients were discussed twice. The benefits consisted mainly of advice on patient medication, diagnosis and the prevention of unnecessary specialist consultations or laboratory examinations. Doctor-doctor teleconsultation allows the rapid resolution of queries which otherwise cause stress to patients and increase the cost and complexity of care.

The telemedicine network of the People's Liberation Army.

In the early 1990s, the People's Liberation Army began to establish a telemedicine network for the non-emergency health-care of the personnel of military units and their families, as well as local civilian patients. All data were transferred over the ordinary telephone network. All the stations were uniformly equipped with PCs containing videoconferencing cards. The network comprised 13 management centres and 208 teleconsultation stations. To evaluate the telemedicine service, we conducted a survey with written questionnaires and telephone interviews. The questionnaire was sent to the person responsible for each telemedicine station. A total of 187 questionnaires were returned, a response rate of 85%. The survey showed that 1503 teleconsultation sessions had been conducted for military as well as civilian patients during the 18-month study period, and 1708 static images had been transferred across the network during these sessions.

The experience in Victoria with telepsychiatry for the child and adolescent mental health service.

In 1995, the Royal Children's Hospital Mental Health Service in Melbourne developed the first telepsychiatry programme in child and adolescent mental health services (CAMHS) in Australia. A survey of 25 CAMHS clinicians in five rural regions who had used videoconferencing showed that 64% had used the technology for more than 18 months, and 20% had used it for 7-12 months. Also, 60% had used the technology on over 30 occasions, and 24% had used it on 20-29 occasions. Respondents clearly recognized its benefits in terms of their increased knowledge and skills (96%), strengthening of relationships with colleagues (92%) and decreased sense of isolation (92%). To build on the success of telepsychiatry there are a number of challenges that health service managers will need to address. Telepsychiatry works most effectively as a tool to complement face-to-face contact. It cannot be promoted as the total solution to the issue of isolation from mainstream services.

The fall and rise of the South Australian telepsychiatry network.

The Rural and Remote Mental Health Service (RRMHS) has delivered telepsychiatry services through the use of videoconferencing to South Australian communities since May 1994. The survivability of the service results from a combination of factors that have seen the RRMHS expand to 48 centres and deliver an average of 100 clinical sessions a month. The key factors responsible for the success of the service lie in the model of service delivery, management support, and the implementation of a system for the scheduling and reporting of videoconference activity. The current model of service delivery has evolved over the past seven years and is fundamentally different to the infrastructure established at the implementation stage of the project. A retrospective analysis shows the shift in service delivery models necessary for the sustainability of telepsychiatry services in South Australia.

Telepathology.

The development of a Queensland-wide videoconferencing network provided an opportunity to develop telepathology. In 1999, weekly videoconferences began with remote laboratories and clinical staff in four peripheral hospitals and the Royal Brisbane Hospital and in 2000 biweekly videoconference pathology grand rounds started across Queensland with up to six sites, from Cairns to the Gold Coast, joining in or presenting. The average number of sites connected was 3.0 in 1998, 3.5 in 1999, 4.4 in 2000 and 4.5 in 2001. Problems included the complexity of the system, timing and need for bookings, coordination of presenters and presentations, and the time needed to organize sessions, set up linkages, advertise sessions and attend the telepathology conference. Successful meetings have been associated with well prepared cases, time for discussion, attendance by all sites, timeliness of cases and responses, and the presence of experts to respond to questions, as well as effective linkages and trouble-free hardware. Future needs include better infrastructure and trained staff to coordinate the linkages and presentations. Telepathology has an important part to play in the provision of cost-effective medical care in Queensland.

Some successes and limitations with telehealth in Canada.

Canada has taken important steps towards establishing telehealth within its health-care system. However, in many areas telehealth in Canada has yet to progress beyond the stage of testing feasibility. A recent survey of eight Canadian telehealth programmes that are using videoconferencing indicated that there is little evidence of either clinical or economic benefits compared with conventional care. There are examples of sustainable, routine telehealth services in Canada. However, overall, the number of patients seen by telehealth is still very small in comparison with the number of face-to-face visits. 'People-related' factors seem dominant in determining the degree of success of telehealth applications.

Clinical call centres: does low-bandwidth video have a place?

Low-bandwidth video has a place in health service delivery. Videoconferencing systems commonly used in telehealth have a high capital cost, take days or weeks to install at specific locations, and have high communications charges. A range of circumstances can be envisaged where video may be of benefit but would not justify the cost of large systems. There are projects in community nursing, home dialysis and post-acute respiratory care where various low-bandwidth video technologies have been added as a supplement to the humble telephone call. It can be expected that at least some of these projects will be able to demonstrate tangible improvements in health outcomes, such as decreased readmission rates, reduced acute episodes of a chronic illness and improved health status from the additional social support.

Telemedicine services for two islands in the Bay of Naples.

In July 1997, telemedicine services were established for two islands, Procida and Ischia, in the Bay of Naples. The telemedicine network allowed a 24 h consultation service to be provided between the islands' health centres and mainland hospitals in the towns of Pozzuoli and Giugliano. Realtime videoconferencing was used, over an ISDN link at 384 kbit/s; radiographs were digitized using a scanner. During 1999 and 2000, there was an average of 46 telemedicine consultations per year from Procida (60% radiology, 30% cardiology, 10% other), 35% of which were emergencies, and 16 training sessions per year; there was an average of 28 telemedicine consultations per year from Ischia (80% radiology, 10% cardiology, 10% other), 10% of which were emergencies, and 12 training sessions per year. The average duration of a telemedicine consultation was 15 min. The total fixed cost of the telemedicine system between the two islands and the two mainland hospitals was approximately Euro 48,000 per year. The total variable costs of the telemedicine service at the observed workload were about Euro 750 per year. The total savings due to telemedicine were approximately Euro 40,000 per year. There was therefore little difference in the overall costs of health-care delivery. The positive consequences of the introduction of the telemedicine service included more rapid diagnosis and treatment, improved quality of service, and the transfer of skills and education. A costs-consequences analysis suggested that the telemedicine service was worthwhile.

Patient satisfaction with telediabetes education in Hong Kong.

Forty-one patients suffering from type 2 diabetes mellitus were selected to receive diabetes education at a local health centre via low-cost videoconferencing equipment. The educational material was transmitted from the diabetic centre of a district hospital. Four educational sessions were carried out over 4.5 months. Satisfaction was measured using a self-administered questionnaire on the completion of the programme. Of the 41 subjects who participated in the study, 36 (88%) completed the questionnaire. Patients reported a high level of satisfaction with most aspects of the education process. The mean total score on the questionnaire was 61.9 (SD 9.4); the highest possible total score was 75. There was a significant positive correlation between age and satisfaction level (r=0.39). The results showed that diabetes education conducted via telemedicine was highly acceptable to diabetic patients.

A review of guidelines and standards for telemedicine.

We conducted a review to establish the range and scope of current telemedicine guidelines and standards. Published guidelines were identified by searching the Medline and Telemedicine Information Exchange (TIE) databases, and by performing a Google search using the term 'telemedicine guidelines'. Three types of guidelines were identified, namely clinical, operational and technical. Clinical guidelines included those for teleradiology, telepsychiatry, home telenursing, minor injuries telemedicine, surgical telemedicine, teledermatology and telepathology. Operational guidelines included those for email communication, Internet access and videoconferencing. Technical guidelines included those from the American Telemedicine Association and the US Office for the Advancement of Telehealth. The main standards relevant to telemedicine include those of the International Telecommunication Union and the DICOM standard. The scarcity of guidelines and standards suggests that telemedicine is not yet near to routine use. If an international telemedicine organization were to take responsibility for defining guidelines, under the direction of clinicians with appropriate telemedicine experience, this might speed up their development.

Social presence in telemedicine.

We studied consultations between a doctor, emergency nurse practitioners (ENPs) and their patients in a minor accident and treatment service (MATS). In the conventional consultations, all three people were located at the main hospital. In the teleconsultations, the doctor was located in a hospital 6 km away from the MATS and used a videoconferencing link connected at 384 kbit/s. There were 30 patients in the conventional group and 30 in the telemedical group. The presenting problems were similar in the two groups. The mean duration of teleconsultations was 951 s and the mean duration of face-to-face consultations was 247 s. In doctor-nurse communication there was a higher rate of turn taking in teleconsultations than in face-to-face consultations; there were also more interruptions, more words and more 'backchannels' (e.g. 'mhm', 'uh-huh') per teleconsultation. In doctor-patient communication there was a higher rate of turn taking, more words, more interruptions and more backchannels per teleconsultation. In patient-nurse communication there was relatively little difference between the two modes of consulting the doctor. Telemedicine appeared to empower the patient to ask more questions of the doctor. It also seemed that the doctor took greater care in a teleconsultation to achieve coordination of beliefs with the patient than in a face-to-face consultation.

Child development services: a multidisciplinary approach to professional education via videoconference.

We have piloted a monthly series of multidisciplinary case discussions via videoconference in the area of child development. The project provided a forum for clinical discussion of complex cases, peer review, professional development and networking for allied health professionals and paediatricians. Six sites in Queensland participated in the project; each site presented at least one case for discussion. The videoconferences ran for 90 min each and were attended by an average of 26 health professionals. The response rate for a questionnaire survey was 71%. The respondents rated the effectiveness of case summaries and the follow-up newsletter very positively. Despite some early difficulties with the technical aspects of videoconferencing, the evaluation demonstrated the participants' satisfaction with the project and its relevance to their everyday practice.

Telehealth for older patients: the Hong Kong experience.

We studied the feasibility, acceptability and cost-effectiveness of using telemedicine to provide geriatric services to residents of nursing homes. A local 200-bed nursing home supported by the community geriatric assessment team (CGAT) participated in a one-year study, during which videoconferencing was used to replace conventional outreach or clinic-based geriatric care. The feasibility of telemedicine was evaluated by participating specialists in a total of 1001 consultations. Other outcome measures included productivity gains, utilization of hospital emergency and inpatient services, and user satisfaction. Telemedicine was adequate for patient care in 60-99% of cases in seven different disciplines. The CGAT was able serve more patients and see them earlier and more frequently. Telemedicine was cheaper than conventional care, and well accepted by health-care professionals as well as clients. Substantial savings were achieved in the study period through a 9% reduction in visits to the hospital emergency department and 11% fewer hospital bed-days. Telemedicine was a feasible means of care delivery to a nursing home and resulted in enhanced productivity and cost-savings. Linking more such institutions to care providers would further increase cost-effectiveness.
