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.

An evaluation of the first year's experience with a low-cost telemedicine link in Bangladesh.

In July 1999, the Swinfen Charitable Trust in the UK established a telemedicine link in Bangladesh, between the Centre for the Rehabilitation of the Paralysed (CRP) in Dhaka and medical consultants abroad. This low-cost telemedicine system used a digital camera to capture still images, which were then transmitted by email. During the first 12 months, 27 telemedicine referrals were made. The following specialties were consulted: neurology (44%), orthopaedics (40%), rheumatology (8%), nephrology (4%) and paediatrics (4%). Initial email replies were received at the CRP within a day of referral in 70% of cases and within thee days in 100%, which shows that store-and-forward telemedicine can be both fast and reliable. Telemedicine consultation was complete within three days in 14 cases (52%) and within three weeks in 24 cases (89%). Referral was judged to be beneficial in 24 cases (89%), the benefits including establishment of the diagnosis, the provision of reassurance to the patient and referring doctor, and a change of management. Four patients (15% of the total) and their families were spared the considerable expense and unnecessary stress of travelling abroad for a second opinion, and the savings from this alone outweighed the set-up and running costs in Bangladesh. The latter are limited to an email account with an Internet service provider and the local-rate telephone call charges from the CRP. This successful telemedicine system is a model for further telemedicine projects in the developing world.

Clinical effectiveness and cost analysis of patient referral by videoconferencing in orthopaedics.

The clinical effectiveness and costs of videoconferencing in orthopaedics between primary and secondary care were examined in an eight-month prospective, comparative study. The general surgery outpatient clinics of two Finnish district hospitals were compared: Peijas Hospital, with telemedicine, and Hyvinkää Hospital, without it. The three study primary-care centres referred a total of 419 adult patients to the outpatient clinics. The population-based number of referrals to Peijas Hospital was similar to that to Hyvinkää Hospital after adjusting for the proportion of older people living in the Hyvinkää Hospital municipalities. Of the 225 patients referred to Peijas Hospital, 168 (75%) were given appointments at the outpatient clinic of surgery and the rest of the referred patients received a teleconsultation. All patients referred to Hyvinkää Hospital were given appointments at the outpatient clinic. The direct costs of an outpatient visit were 45% greater per patient than for a teleconsultation, with a marginal cost decrease of EU48 for every new teleconsultation. A cost-minimization analysis of the alternative interventions showed a net benefit of EU2500 in favour of teleconsultations. The use of videoconferencing between primary and secondary care was modest in orthopaedics, although the use of this telemedicine method was shown to reduce direct costs and be cost-effective.

A cost-minimization analysis of the societal costs of realtime teledermatology compared with conventional care: results from a randomized controlled trial in New Zealand.

A randomized controlled trial was carried out to measure the societal costs of realtime teledermatology compared with those of conventional hospital care in New Zealand. Two rural health centres were linked to a specialist hospital via ISDN at 128 kbit/s. Over 10 months, 203 patients were referred for a specialist dermatological consultation and 26 were followed up, giving a total of 229 consultations. Fifty-four per cent were randomized to the teledermatology consultation and 46% to the conventional hospital consultation. A cost-minimization analysis was used to calculate the total costs of both types of dermatological consultation. The total cost of the 123 teledermatology consultations was NZ$34,346 and the total cost of the 106 conventional hospital consultations was NZ$30,081. The average societal cost of the teledermatology consultation was therefore NZ$279.23 compared with NZ$283.79 for the conventional hospital consultation. The marginal cost of seeing an additional patient was NZ$135 via teledermatology and NZ$284 via conventional hospital appointment. From a societal viewpoint, and assuming an equal outcome, teledermatology was a more cost-efficient use of resources than conventional hospital care.

Teledermatology in the Waikato region of New Zealand.

Teledermatology consultations over a video-link began at Health Waikato in 1995. Clinical trials involving about 500 patients have demonstrated the diagnostic accuracy and economic gains of these teleconsultations, and patient satisfaction with them. Yet, six years on, out-of-date equipment remains under-used. There has been no expansion of the network and no additional clinical teleconsultation services. Possible reasons include the excessive capital cost of videoconferencing equipment, clinician overwork, inconvenience, lack of reimbursement, administrative and governmental inertia, and little demand from patients and their doctors. To widen our referral base without the inconvenience of videoconferencing, we decided to offer a secure browser-based dermatology tele-advice service to referring general practitioners who owned digital cameras. With the increase in online health information and electronic communication, we assumed it would be popular. But, despite up to six-month waits for patients to be seen in the dermatology outpatient clinic, few patients have been referred to the service. Explanations have included time constraints, unavailability of a camera, no Internet access at the time of consultation and lack of reimbursement. Can we look forward to a future in which all doctors have high-speed access to the Internet at their desktop through their practice management systems? Who will pay? Will they continue to prefer conventional referral?

Changes in the job situation due to telemedicine.

Little is known either about how telemedicine changes the job situation or about how the working environment might be improved for those involved in telemedicine. To investigate these issues, qualitative interviews were carried out with 30 people in Norway working with telepsychiatry (12 respondents), teledermatology (six respondents), a telepathology frozen-section service (10 respondents) and tele-otolaryngology (two respondents). The median annual number of remote consultations in telepsychiatry was nine, in teledermatology 81 and in the telepathology frozen-section service nine. The positive aspects of working with telemedicine included less travelling, which gave more time for other work, less need to travel in poor weather, new contacts, an increased sense of professional security (because support was readily available) and the satisfaction of seeing partners in communication. At its present volume, telemedicine generally fits into daily work patterns quite well. Problems do occur, but they can be solved by appropriate organizational measures. Long-term scheduling of telemedical sessions may be important. Many telemedicine workers want to have the equipment in their own office. Working with telemedicine can be tiring and those interviewed wanted to limit the number of hours per week. A solution may be to use large clinics, such as university clinics, where the telemedical work could be distributed between several specialists. Large telemedicine clinics with a full-time dedicated staff would need careful consideration of working practices.

Teleconsultation as a replacement for referral to an outpatient clinic.

We conducted a randomized case control study of referrals from a primary care centre in Finland. All the consultations and referrals from seven general practitioners (GPs) dealt with by internists and surgeons at Satakunta Central Hospital in Pori and geriatricians at Satalinna Hospital in Harjavalta over five months were included. For patients in the control group, a conventional referral letter was sent to the hospital outpatient clinic. For patients in the intervention group, the GPs had to decide whether they wanted an electronic consultation with the hospital or wanted to refer the patient (i.e. to transfer responsibility for treatment). Communication with the hospital specialist was then via a secure Web-based system. Ninety-three patients consented to participate in the study. None refused, although there were 15 non-attenders. Satisfaction data were collected from questionnaires completed by the patients and doctors. All the patients treated by teleconsultation said that they wanted the same procedure in future and 63% of the control group said they would prefer a teleconsultation next time. The doctors quickly learned to exploit the telemedicine model successfully. The responsibility for treatment was maintained in the health centre in 52% of cases using teleconsultation, without any visit to hospital being required. The GPs and the hospital doctors agreed on the follow-up treatment. Telereferral increased the possibility of the GP maintaining responsibility for the treatment. The reduced number of hospital visits in the telemedicine model should produce significant cost savings.

Transfer of knowledge from the specialist to the generalist by videoconferencing: effect on diabetes care.

We conducted a 12-month prospective interventional study of videoconferencing between primary and secondary care. A treatment network consisting of a diabetes specialist and four general practitioners was established. The communications medium was PC-based videoconferencing via ISDN at 128 kbit/s. A total of 154 type 2 diabetic patients entered the study. The specialist was contacted 94 times via videoconferencing. Metabolic and haemodynamic parameters were significantly improved over the course of the study: the mean HbA1c level fell from 8.1% to 7.8%, systolic blood pressure from 156 to 148 mmHg and diastolic blood pressure from 88 to 83 mmHg. The study demonstrated that therapeutic counselling by videoconferencing is feasible in diabetes care and suggests that it reduces hospital admissions and improves the quality of care.

Organizational aspects of e-referrals.

Three different, well established systems for e-referral were examined. They ranged from a system in a single country handling a large number of cases (60,000 per year) to a global system covering many countries which handled fewer cases (150 per year). Nonetheless, there appeared to be a number of common features. Whether the purpose is e-transfer or e-consultation, the underlying model of the e-referral process is: the referrer initiates an e-request; the organization managing the process receives it; the organization allocates it for reply; the responder replies to the initiator. Various things can go wrong and the organization managing the e-referral process needs to be able to track requests through the system; this requires various performance metrics. E-referral can be conducted using email, or as messages passed either directly between computer systems or via a Web-link to a server. The experience of the three systems studied shows that significant changes in work practice are needed to launch an e-referral service successfully. The use of e-referral between primary and secondary care improves access to services and can be shown to be cost-effective.

Assessment of benefit in tele-ophthalmology using a consensus panel.

A videoconferencing link was established from a hospital in South Africa to Moorfields Eye Hospital in London. A clinician in South Africa used a video slit-lamp and videoconferencing equipment to capture images and communicate with a specialist in London. Over 12 months, 113 cases were discussed in teleconsultations. Case-notes were subsequently obtained for 90 cases (80%). Three consultant ophthalmologists took part in the consensus process, one from the UK and two from South Africa. The consensus panel achieved on average 78-96% agreement on the items rated. In approximately half the cases, the panel judged that teleconsultation had had an effect on diagnosis. In nine cases (10%) there was potential for definite improvement in visual health as a result of tele-ophthalmology and in a further 48 cases (53%) there was potential for possible improvement in visual health. The consensus process identified 35 cases (39%) where there was potential improvement in general health as a result of tele-ophthalmology. Despite the methodological limitations of our approach, it was possible to learn a great deal about the effectiveness of the telemedicine intervention.

A simple telemedicine system to provide second-opinion advice to the patients of an Albanian diagnostic centre.

Since August 2003, the IKEDA Klinika diagnostic centre in Tirana, Albania, has offered patients telemedical help from Greece. The teleconsultation service is based on Internet technologies adapted to telemedical use, including the use of forms (e.g. for the patient history), multimedia file exchanges (e.g. for radiographs and electroencephalograms) and videoconferencing. The teleconsultants assist in treatment planning and, when necessary, in organizing the transfer of patients to Greece. The four cornerstones of the service are: the provision of second opinions by telemedicine; assistance in treatment planning; assistance to patients during transfer; and the continuity of medical care on their repatriation. Based on the first six months of operation, we estimate that, if bureaucratic visa restrictions to patient movement between Albania and Greece are removed, more than 2000 patients per year will benefit from the service and more than 400 patients will be transferred to Greek hospitals for treatment.

Prospective case review of a global e-health system for doctors in developing countries.

The Swinfen Charitable Trust has managed email consultations for doctors in developing countries since 1999. The process was handled manually for the first three years and then subsequently using an automatic message-handling system. We conducted a prospective review of email consultations between referring doctors and consulting specialists during six months of automatic operation (December 2003 to May 2004). During the study period 125 consultations took place. These concerned a wide range of specialties (e.g. orthopaedics 17%, dermatology 16%, obstetrics and gynaecology 11%, radiology 10%). Of these referrals, 33% (41) were for paediatric cases. Consulting specialists, who were based in five countries, were volunteers. Referring doctors were from 24 hospitals in 12 developing countries. The median time from referral to definitive reply was 1.5 days (interquartile range 0.6-4.9). There was an 85% response rate (n = 106) to a survey concerning the value of the consultation to the referring doctor. All the referring doctors who responded made positive comments about the service and half said that it improved their management of the case. The second-opinion consultation system operated by the Swinfen Charitable Trust represents an example of a global e-health system operated for altruistic, rather than commercial, reasons.

Evaluation of a pilot second-opinion child telepsychiatry service.

A second-opinion child psychiatry service was piloted for six months in the northern-most two-thirds of Queensland. It provided specialist expertise by telehealth to local multidisciplinary teams of mental health staff. During the study period, 28 videoconferences were performed by the service: nine for administrative purposes, two for educational purposes, and 17 for direct and indirect clinical applications. The mean time between a referral being made and a consultation being performed was 4.7 days (range 1-13). A survey administered to referring and non-referring mental health workers showed that the major barriers to service implementation included the limited allied health applications that were offered, a perceived lack of communication during the implementation phase of the service, and the creation of a new referral network that did not conform to traditional referral patterns in the north of Queensland.

The use of telemedicine in the management of vascular surgical referrals.

We have performed a feasibility study of telemedicine as an alternative to conventional outpatient appointments for the making of diagnostic and management decisions for patients referred for vascular surgery. Twenty-two sequential patients referred by a single general practice to a vascular centre were offered a telemedicine clinic appointment as an alternative to a conventional hospital outpatient appointment. A referral pro forma and digital photograph (where appropriate) were transmitted in advance of the videoconference. The videoconference involved patient, practice nurse and vascular consultant. All patients opted for the teleconsultation. The majority had leg ulceration or leg pain. Six patients required only the initial teleconsultation and were managed thereafter in the community. Thirteen were referred to the vascular laboratory for investigation. Three proceeded to angioplasty and four to surgery. Two patients had a conventional outpatient appointment for follow-up but all others were followed up via telemedicine. Overall 27 conventional outpatient appointments were replaced by a teleconsultation.

Trial of low-cost teledermatology in primary care.

We examined the feasibility of a low-cost, store-and-forward teledermatology service for general practitioners (GPs) in regional Queensland. Digital pictures and a brief case history were transmitted by email. A service coordinator carried out quality control checks and then forwarded these email messages to a consultant dermatologist. On receiving a clinical response from the dermatologist, the service coordinator returned the message to the referring GP. The aim was to provide advice to rural GPs within one working day. Over six months, 63 referrals were processed by the teledermatology service, covering a wide range of dermatological conditions. In the majority of cases the referring doctors were able to treat the condition after receipt of email advice from the dermatologist; however, in 10 cases (16%) additional images or biopsy results were requested because image quality was inadequate. The average time between a referral being received and clinical advice being provided to the referring GPs was 46 hours. The number of referrals in the present study, 1.05 per month per site, was similar to that reported in other primary care studies. While the use of low-cost digital cameras and public email is feasible, there may be other issues, for example remuneration, which will militate against the widespread introduction of primary care teledermatology in Australia.

Telemedicine consultations: failed cases and floundering specialties.

The Arizona Telemedicine Program began as a multi-service provider, with teleconsultations in over 53 subspecialties. Although new sites often use numerous subspecialties at first, this is typically followed by a longer period when only a few subspecialties are used. A retrospective analysis of the referral rates from the sites showed wide variations, some exhibiting extreme fluctuations. There was a high correlation (0.84) between personnel turnover rates at each site (i.e. the number of personnel changing) and the degree to which the fluctuations were 'out of control'. Over six years, 402 teleconsultations were scheduled but did not occur. Of these, 82% were closed with no further contact, although 63% were managed eventually via telemedicine, all in telepsychiatry. The reasons for these appointments not taking place were that the patient did not show up (45%), the patient cancelled (32%), the telepsychiatrist cancelled (22%) or bad weather prevented travel (1%). Of the unsuccessful teleconsultations, 84% were realtime and 16% were store and forward. The average cost to the provider of a missed realtime teleconsultation was US$228 for a 1 h session.

Telephone advice nursing services in a US health maintenance organization.

We studied telephone advice nursing (TAN) in the US. We recorded 4269 TAN calls in four regions served by Kaiser Permanente, a health maintenance organization. A call description form was used to record information regarding both calls and callers. The mean call length was 5.9 min (SD 3.6, range 0.3-35.8); 300 calls lasted less than 2 min. The mean call length differed significantly across regions, from 4.4 min in Hawaii to 8.7 min in Southern California. Calls to call centres lasted an average of 6.5 min (SD 3.8), compared with 4.2 min (SD 2.9) for those to medical offices. These differences were significant. Although 42% of calls required some further medical management, only 18% (n = 754) resulted in an urgent disposition, and only 16% (n = 121; 3% of all calls) of the urgent dispositions involved referral to emergency services. The likelihood of urgent disposition varied significantly by region. Callers generally used the TAN services for the right reasons, that is, with questions or concerns that could be reasonably handled by telephone advice nurses.
