Recent advances in telepsychiatry: an updated review.

OBJECTIVE: In response to new developments and interest in the area of telepsychiatry, literature on this topic has greatly increased over the past three years. Because of this increase, the authors conducted a literature review of telepsychiatry to update a previously published review that covered the years 1970 to 2000. METHODS: A search was conducted on the MEDLINE, PsycINFO, and Telemedicine Information Exchange (TIE) databases for literature published from March 2000 to March 2003 on telepsychiatry applications, using the following terms: telepsychiatry, telepsychology, telemental health, videoconferencing, and video conferencing. RESULTS: Sixty-eight publications were identified over this three-year period, exceeding the 63 publications identified in the previous literature review. The authors summarize the results of findings in six areas: novel clinical demonstrations and current program descriptions; the reliability of clinical assessments; clinical outcomes; satisfaction of patients and clinicians; cost and cost-effectiveness; and legal, regulatory, and ethical issues. Studies describing existing programs and novel clinical applications support the belief that the use of telepsychiatry is expanding. Overall, studies continued to support the notion that telepsychiatry assessments can produce reliable results, telepsychiatric services can lead to improved clinical status, and patients and clinicians are satisfied with treatment delivered via telepsychiatry. Evidence supported the notion that telepsychiatry is a cost-effective means of delivering mental health services; however, this conclusion was based on limited studies of economic models of telepsychiatry programs. Also limited were papers on the topics of legal, regulatory, and ethical issues. CONCLUSIONS: Despite the rapid increase in information on telepsychiatry, methodologically sound studies in the area of telepsychiatry are still infrequent.

Models of telepsychiatric consultation--liaison service to rural primary care.

New models of psychiatric intervention are needed to improve the accessibility of mental health care in the primary-care setting, particularly in rural areas of the United States. Some models of service delivery have been successful in suburban and urban settings, but they do not always apply to rural settings. "E-health" innovations like videoconferencing, telephone, secure messaging (e-mail), and the Internet are increasingly being used to provide consultation--liaison service to primary care. This article briefly reviews successful models used in primary care, their application to rural sites, new models for rural sites, and suggestions for future e-health research.

Collaboratories: leveraging information technology for cooperative research.

Economic, organizational, and societal pressures, as well as the desire to reach shared goals more efficiently and effectively, are driving an increase in collaborative research. Research collaborations frequently occur among participants separated by temporal, geographical, organizational, disciplinary, and cultural boundaries. Increasingly complex collaborative projects focus attention on the question of how to facilitate working together. Through so-called collaboratories, information technology can play an important role in addressing this question. A collaboratory can be defined as an information technology infrastructure that supports cooperation among individuals, groups, or organizations in pursuit of a shared goal by facilitating interaction, communication, and knowledge-sharing. Tools such as Web-based collaborative workspaces, Internet discussion lists/newsgroups/real-time chat, screen- and application-sharing, Web-based conferencing, online Web page mark-up, automatic notification, and videoconferencing can be used to implement collaboratories. Collaboratories have significant potential to facilitate cooperative research, but should be evaluated carefully to determine best practices.

Telepsychiatry consultations to a rural nursing facility: a 2-year experience.

This report describes the operation of a telepsychiatry consultation service provided from an academic medical center to a skilled nursing facility in a rural setting. Seventy-one consultations via low-cost ISDN videoconferencing equipment were provided over the 2-year period to 40 patients. The average duration of the consultation period was about 3 months. A wide variety of diagnostic conditions were encountered, with the majority being either depression or dementia-related behavior problems. Advantages of the program included the ability to respond promptly to rural patients' clinical needs, the flexibility to consult more frequently if clinically indicated, and more efficient use of the consultant's time, as travel time was eliminated. The program is an example of how telepsychiatry can successfully expand access to mental health services to residents of long-term care facilities.

Telemedicine use and the reduction of psychiatric admissions from a long-term care facility.

Copper Ridge is a long-term care facility that provides care for persons with dementia and their families from early diagnosis to end of life. A low-cost videoconferencing system was employed in the development of a comprehensive, integrated continuum of care for Copper Ridge residents by bridging long-term care with inpatient psychiatric care at Johns Hopkins Hospital. In this article, we discuss the Copper Ridge/Johns Hopkins telemedicine project and how its operation appears to have brought about a reduction in psychiatric admissions. Telemedicine projects using inexpensive technology over standard telephone lines can be successfully used in long-term care settings.

The use of telepsychiatry in the brief counselling of non-psychotic patients from an inner-London general practice.

Brief counselling of 13 non-psychotic patients was carried out using an interactive television link, in order to assess patient satisfaction with this technique. Informed consent was obtained from all patients before the videoconferencing sessions, which were conducted at 128 kbit/s. Over the four-month study period, 11 men and two women participated in a total of 29 sessions. A total of 28 questionnaires were completed. After the sessions, 93% of patients agreed that they would like to use this medium for communication again, 75% stated that they were able to see everything that they needed to see and 86% agreed that they were able to hear everything they needed to hear. Overall, these findings indicate that patients were happy with the standard of care they received.

Utilization and practical aspects of tele-ophthalmology between South Africa and the UK.

A tele-ophthalmology service was established between a regional hospital in South Africa and a specialist eye hospital in the UK. The aim of the service was to provide secondary specialist advice in the diagnosis and treatment of difficult ophthalmology cases in South Africa. Over 12 months, the South African medical officers saw 16,458 ophthalmology patients and would have liked a second opinion in 5.7% of these cases. Case discussions conducted by videoconferencing at 384 kbit/s were carried out in 0.5% of cases. No significant connection problems were experienced during the 12-month study period. On 4% of occasions, the case discussions were conducted at a bandwidth of 256 kbit/s, but this did not affect the quality of the still images. The South African medical officers valued the educational benefits gained from the case discussions with the UK specialists.

Tele-ophthalmology for the treatment in primary care of disorders in the anterior part of the eye.

Desktop videoconferencing at 384 kbit/s was used for a trial of tele-ophthalmology consultations between a general practitioner (GP) and an experienced ophthalmologist. Forty-two consecutive patients from St Erik's Eye Hospital emergency ward with disorders in the anterior part of the eye were examined. There was an excellent correlation between the diagnoses made with telemedicine support and those made by the ophthalmologist directly. Subsequently, the GP made 121 eye examinations in two years out of a total of approximately 300-400 examinations at the health-care centre. In the first year the GP examined and treated 45-50% of the cases on his own and 30-50% with telemedicine support. In the second year he treated 55-80% of the cases on his own and 5-35% with telemedicine support. Tele-ophthalmology in primary care appears to be reliable and is likely to be valuable in rural areas, where the distance to an ophthalmologist can be a significant obstacle to satisfactory diagnosis and treatment.

Avoiding artificiality in teleconsultations.

The ideal videoconferencing environment would produce the minimum feeling of artificiality for its users. We assessed nurse and patient perceptions of artificiality by varying the technical and operational procedures for telemedicine in a minor injuries unit. Twenty-five patients and eight emergency nurse practitioners (ENPs) participated in simulated teleconsultations under a variety of different conditions and completed a Likert-scale survey. There was a close correlation between the ENPs' ratings and the patients' ratings for the various factors (r > 0.99). In relation to technical factors, a flicker-free television screen and the user being seated close to the screen were preferred. Similarly, in relation to operational procedures, an initial explanation of telemedicine, introductions and adequate preparation were also preferred. The study suggests that careful attention to technical specifications and operational procedures can reduce the perceived artificiality of teleconsultations.

The development of a telemedicine system for a centralized maxillofacial unit serving four towns.

Following the amalgamation on one site of inpatient oral and maxillofacial surgical (OMFS) services serving four towns, patients attending accident and emergency (A and E) departments in Bolton, Burnley and Bury who required specialist OMFS care were transferred to Blackburn. This sometimes led to inappropriate transfer, with inconvenience for patients, sub-standard care and wasted resources. To reduce these problems, a videoconferencing system was established, linking the A and E departments of three peripheral hospitals to the central site. This allowed realtime visualization of patients and their radiographs, discussion between clinicians and transfer of a summary data-sheet. The aim was to improve remote diagnosis and to deliver a cost-effective, high-quality specialist service. In the first 12 months, there were an average of 25 remote consultations per month, with favourable feedback from both patients and clinicians.

Cost implications of outpatient teleneurology.

A randomized controlled trial was conducted to compare the costs of realtime teleneurology with the cost of conventional neurological care. Two district hospitals in Northern Ireland were equipped with videoconferencing units and were connected to the regional neurological centre by ISDN at 384 kbit/s. Of 168 patients randomized to the study, 141 kept their appointments (76 male, 65 female). Sixty-five patients were randomized to a conventional consultation while 76 were randomized to a teleconsultation. The average age was 44 years of those seen conventionally and 42 years of those seen by telemedicine. The groups had similar diagnoses. The telemedicine group required more investigations and reviews than the conventional group. The average cost of the conventional consultation was 49 pounds sterling compared with 72 pounds sterling for the teleconsultation. Realtime teleneurology was not as cost-effective as conventional care.

Managing telemedicine: from noble ideas to action.

The aim of the present study was to elucidate how telemedicine can be used in an integrated and comprehensive manner. Two Swedish telemedicine projects were studied. The technical platform was an ISDN videoconferencing system which could be connected to various items of medical equipment. The first project, general telemedicine, concerned communication between two primary care centres, one county hospital and one university hospital. The specialties involved were dermatology, orthopaedics and otolaryngology. The second project, telepathology, included pathology and cytology at the university hospital, and surgery and gynaecology at a county hospital. The first round of interviews was conducted to reveal the expectations of the physicians regarding the potential benefits and applications of the technology and potential organizational obstacles. Subsequent interview rounds were carried out to reveal what had happened since the previous interview. In total 62 interviews were carried out with 32 respondents. The main conclusions were that the technology's generic features, namely the transmission of pictures and sound, had been translated into appropriate fields of application, which had been diffused and routinized in organizational activities. In order to facilitate this process, there were two crucial issues for managers. First, due to the 'openness' of the technology, actors who had the will to test the limits of the technology had to be identified and engaged. Second, while the use of the new technologies implied that new patterns of action were established, it was necessary to discover and develop routines that could be used as a facilitator for the further use of telemedicine.

An economic evaluation of the Highlands and Islands teledentistry project.

A 12-month trial of teledentistry was conducted in two general dental practices (one in the Orkney Islands and one in the Scottish Highlands at Kingussie). The dental practices had a PC-based videoconferencing link, connected by ISDN at 128 kbit/s, to a restorative specialist at a hospital in Aberdeen. Twenty-five patients were recruited into the trial. A cost-minimization analysis was undertaken by comparing the costs of teledentistry with two alternatives: outreach visits, where the specialist regularly visited the remote communities, and hospital visits, where patients in remote communities travelled to hospital for consultation. For Orkney patients, dental teleconsultations cost the National Health Service (NHS) an additional 36 per patient compared with outreach visits, but cost-savings of 270 per patient could be achieved compared with hospital visits. For Kingussie patients, teleconsultations cost the NHS an additional 44 and there were cost-savings of 1.54 compared with outreach visits and hospitals visits, respectively. However, patients incurred additional costs for radiographs and photographs, and the general dental practitioner incurred additional preparation time costs. When the value of patient time was included, there were cost-savings of around 900 per Orkney patient compared with hospital visits, but compared with outreach visits teledentistry cost an additional 180 per patient. Based on the trial data, there were no cost-savings from teledentistry for Kingussie patients, even when the value of time was included. These results were relatively robust in a sensitivity analysis. However, we estimated that the cost-effectiveness of teledentistry would improve with greater familiarity and use of equipment. Benefits and cost-savings would be greatest in island or remote communities, where patients have to travel long distances to hospital for specialist consultations.

Comparison of asynchronous and realtime teleconsulting for orthopaedic second opinions.

We studied a teleconsulting service for second opinions in orthopaedics. Three units of the national insurance organization for accidents at work were connected to a large orthopaedic hospital in Bologna. During a 20-month study, 65 consultations were provided: 51 (78%) by asynchronous (store-and-forward) consulting and 14 (22%) by realtime videoconferencing. All the consultations made use of radiology images (radiographs, computerized tomography scans, magnetic resonance imaging scans and ultrasound scans). Video-messages and still images were commonly used to support the asynchronous consultations. More data were transmitted on average for an asynchronous teleconsultation (8 MByte) than in a videoconference (5 MByte). The average time spent by orthopaedic specialists was slightly longer in videoconferences (21 min, SD 8) than in asynchronous teleconsultations (19 min, SD 8). The clinicians confidence in their diagnosis was generally good but was lower in asynchronous consultations. The main problem affecting the telemedicine service was the lack or the low quality of the information received from the referring sites. The clinical complexity of the case and the organizational requirements were declared to be the main factors affecting the choice of consulting procedure. The study showed that the asynchronous method was preferred in the majority of cases and could be easily integrated into clinical practice, although there were some concerns about the diagnostic quality of the information transmitted.

Evaluation of a pilot telemedicine network for accident and emergency work.

A pilot accident and emergency teleconsulting service was established in Scotland. It was based at the accident and emergency department of the main hospital in Aberdeen. There were three peripheral sites in rural Grampian (Peterhead, Turriff and Huntly) and one in the Shetland Isles. The videoconferencing equipment used was connected by ISDN at 384 kbit/s. During the 15 months of the study, 1998 videoconference calls were made, of which 402 (20%) calls were made to the accident and emergency department for clinical consultations. The majority of the clinical calls (95%) were made between 09:00 and 17:00, and more than 90% were completed within 20 min. During the majority of calls (87%) one or more X-ray images were transmitted. The majority of patients (89%) received treatment without transportation to the main centre in Aberdeen. The present study demonstrated that accident and emergency teleconsultations can be technically reliable, effective in reducing the number of patient transfers and acceptable to the referring clinicians. As a result, approximately 1.5 million has been made available by the government to develop a national system for Scotland.

Child advocacy outreach: using telehealth to expand child sexual abuse services in rural Kentucky.

We evaluated the use of videoconferencing as an educational and consultative tool for physicians and mental health staff providing services for child victims of sexual abuse in rural Kentucky. The number of counties with access to sexual abuse examinations by a qualified physician increased from 16 to 23 in the first year and to 54 in the second. The number of cases increased from 77 to 83 in the first year and to 339 in the second year. The number of consultations increased from zero to eight in the first year and to 74 in the second year. A user survey showed that the equipment supported clinical decision making, was useful and was easy to use. However, it was not as effective for case conferencing as for one-to-one interactions. Rural health professionals knowledge of child sexual abuse increased.

Community coronary units: strategies to promote pre-hospital thrombolysis.

Early diagnosis and the early delivery of pre-hospital thrombolysis in cases of acute myocardial infarction (AMI) have been shown to decrease mortality. Despite strong evidence of its benefits, pre-hospital thrombolysis rates are still worryingly low. The challenge is to empower community practitioners to deliver thrombolysis. In the Grampian region there is a network of community hospitals which have been equipped with both videoconferencing and remote telemetry equipment. This allows realtime consultation with the local accident and emergency department and coronary care unit. Early trials of the system show that clinical information can be viewed in realtime, with transfer of a 12-lead electrocardiogram at 60 s intervals. This will give general practitioners unprecedented access to specialist advice. Our aim is to use a combination of teaching and decision support technology to ensure that all patients with AMI have the opportunity to access timely and appropriate prehospital thrombolysis.
