Telepsychiatry and geriatric care.

The use of telecommunications--telephone, computer, videoconferencing equipment--to provide mental health services at a distance has grown rapidly. This review encompasses reports from programs that provide telepsychiatry services, including telephone- and computer- based education and support services, telephone screening for dementia, and the use of videoconferencing to provide psychiatric consultations, health education, and administrative support. The extensive experience to date supports the value of telepsychiatry. Applications in geriatric settings and research involving geriatric subjects are reviewed. Cost analyses and economic evaluations of telepsychiatry are preliminary at this time and need further refinement. There is great potential for using telecommunications to expand access to mental health services to underserved geriatric populations.

A study of the application sharing capabilities in telemedicine.

The main aim of this study was to find out if the image format (TIFF or JPEG) influenced the time delay for transferring radiological images by the application sharing tool of a desktop videoconferencing system. The second task of the study was to define a procedure that optimized the time delay to load and remotely visualize the images. The results were achieved by applying a test procedure called 'benchmark protocol'. The videoconferencing system used for the test was Intel ProShare 200 v2.0. The image transfer was performed by a BRI ISDN connection. We showed that the image format had no significant influence on the time delay. We presented an optimal procedure for image transfer. Furthermore, store and forward procedures with simple file transfer were shown to be inferior to the use of application sharing. For radiological image transfer we recommend to use lossless file formats and application sharing with the image already loaded in because this method achieves the lowest time delays.

A national network for the tele-education of Canadian residents in pediatric cardiology.

A trial of 11 video-conferenced teaching sessions for residents in pediatric cardiology was performed by the 7 training programs in Canada in order to share expertise in specialized areas, to expose trainees to educational telemedicine, and to acquaint residents with other programs and personnel. Topics included cardiac pathology, arrhythmias, magnetic resonance imaging, fetal physiology, pulmonary hypertension, and cardiomyopathy. The sessions were evaluated by 93 residents by questionnaire for content and technology. Session content was highly rated. Videoconference picture quality was highly rated, but sound quality and visual aids were rated as neutral or unsatisfactory by a significant minority, related to problems with several early sessions, subsequently corrected. 60% of respondents rated the videoconferences as good as live presentations. Presenters were generally satisfied although they required some adjustments to videoconferencing. The average cost per session was $700 Canadian. Videoconferencing of resident educational sessions was generally well accepted by most presenters and residents, and the trial has formed the basis for a national network. Adequate organizational time, and careful attention to audiovisual needs, are most important. Videoconference guidelines are suggested for presenters based on this experience.

Comparison of teleconsultations and face-to-face consultations: preliminary results of a United Kingdom multicentre teledermatology study.

The objective of this multicentre study was to undertake a systematic comparison of face-to-face consultations and teleconsultations performed using low-cost videoconferencing equipment. One hundred and twenty-six patients were enrolled by their general practitioners across three sites. Each patient underwent a teleconsultation with a distant dermatologist followed by a traditional face-to-face consultation with a dermatologist. The main outcome measures were diagnostic concordance rates, management plans and patient and doctor satisfaction. One hundred and fifty-five diagnoses were identified by the face-to-face consultations from the sample of 126 patients. Identical diagnoses were recorded from both types of consultation in 59% of cases. Teledermatology consultations missed a secondary diagnosis in 6% of cases and were unable to make a useful diagnosis in 11% of cases. Wrong diagnoses were made by the teledermatologist in 4% of cases. Dermatologists were able to make a definitive diagnosis by face-to-face consultations in significantly more cases than by teleconsultations (P = 0.001). Where both types of consultation resulted in a single diagnosis there was a high level of agreement (kappa = 0.96, lower 95% confidence limit 0.91-1.00). Overall follow-up rates from both types of consultation were almost identical. Fifty per cent of patients seen could have been managed using a single videoconferenced teleconsultation without any requirement for further specialist intervention. Patients reported high levels of satisfaction with the teleconsultations. General practitioners reported that 75% of the teleconsultations were of educational benefit. This study illustrates the potential of telemedicine to diagnose and manage dermatology cases referred from primary care. Once the problem of image quality has been addressed, further studies will be required to investigate the cost-effectiveness of a teledermatology service and the potential consequences for the provision of dermatological services in the U.K.

Teledermatology: a review.

Teledermatology holds great potential for revolutionizing the delivery of dermatology services, providing equitable service to remote areas and allowing primary care physicians to refer patients to dermatology centres of excellence at a distance. However, before its routine application as a service tool, its reliability, accuracy and cost-effectiveness need to be verified by rigorous evaluation. Teledermatology can be applied in one of two ways: it may be conducted in real-time, utilizing videoconferencing equipment, or by store-and-forward methods, when transmitted digital images or photographs are submitted with a clinical history. While there is a considerable range of reported accuracy and reliability, evidence suggests that teledermatology will become increasingly utilized and incorporated into more conventional dermatology service delivery systems. Studies to date have generally found that real-time dermatology is likely to allow greater clinical information to be obtained from the patient. This may result in fewer patients requiring conventional consultations, but it is generally more time-consuming and costly to the health service provider. It is often favoured by the patient because of the instantaneous nature of the diagnosis and management regimen for the condition, and it has educational value to the primary care physician. Store-and-forward systems of teledermatology often give high levels of diagnostic accuracy, and are cheaper and more convenient for the health care provider, but lack the immediacy of patient contact with the dermatologist, and involve a delay in obtaining the diagnosis and advice on management. It is increasingly likely that teledermatology will prove to be a significant tool in the provision of dermatology services in the future. These services will probably be provided by store-and-forward digital image systems, with real-time videoconferencing being used for case conferences and education. However, much more research is needed into the outcomes and limitations of such a service and its effect on waiting lists, as well as possible cost benefits for patients, primary health care professionals and dermatology departments.

A child and adolescent psychiatric outreach service for rural New South Wales: a telemedicine pilot study.

OBJECTIVE: To examine the feasibility of a tertiary outreach service in child and adolescent psychiatry to two rural health centres in New South Wales, Australia. METHODS: Following a site visit to Dubbo Hospital and Bourke Hospital, telemedical videoconferencing was provided for 2 h/week for 32 weeks. Details of referrers, patients' diagnosis and outcome, and satisfaction with the service were obtained. RESULTS: Cases were triaged by a nominated rural adolescent mental health worker. The service provided detailed assessment and management of servere, complex, mental and neuropsychiatric disorders. Fifty-four young people were assessed and 72 joint consultative videoconferencing interviews were undertaken, including 26 initial consultations. Twenty-three initial consultations were undertaken on the visit to the rural centres. Clinical descriptions illustrate the flexibility and sensitivity of the service. CONCLUSION: Telepsychiatry provides access to a flexible, effective tertiary service for those with special, complex needs, including the disadvantaged or isolated. It makes a valuable economic contribution to supporting and educating rural health professionals, thereby enriching rural mental health services.

Rehabilitation professionals' satisfaction with continuing education delivered at a distance using different technologies.

This paper examines learner satisfaction with technologies used for distance delivery of continuing education across 10 Canadian sites: nine within the province of Alberta and one in Nunavut Territory. The technologies were satellite (or videotapes of) broadcasts, videoconferencing, and web-based technology. Learner satisfaction was evaluated using questionnaires. A survey on general issues related to continuing education was developed and mailed to random samples of health professionals and a convenience sample of stakeholders. The learners (n = 1,141) represented 20 types of health service providers who had attended at least one session delivered via satellite, videotape, or videoconferencing. Seven individuals completed the web-based course. Overall, the majority of participants were satisfied or very satisfied. In general, satellite delivery was received more favorably compared with videotapes of the same content. A total of 350 (33% response rate) health professionals and 37 (50% response rate) stakeholders returned the surveys. Nearly 50% of health professionals thought that clinical case presentations (rounds) were valuable to them, but over half of the stakeholders perceived that videotapes, rounds, and research seminars were valuable to health professionals. Ratings for the web-based course varied, indicating different learner characteristics. We conclude that it is possible to utilize multiple technologies to meet the continuing education needs of an interdisciplinary group of health service providers, but future research is needed to develop a framework for evaluating the usability of multiple existing and emerging technologies for distance education.

Evaluation of a telemedicine link between Darwin and Adelaide to facilitate cancer management.

The videoconferencing link between the Royal Adelaide Hospital Cancer Centre in South Australia and the Royal Darwin Hospital in the Northern Territory was established to allow Darwin clinicians to discuss cases in multidisciplinary oncology meetings at the tertiary referral center. This was evaluated by questionnaires distributed to the 20 health professionals involved and a group of 8 patients with breast cancer whose case histories had been discussed via videoconferencing. All clinicians found the telemedicine link to be either useful or very useful in at least one aspect of their practice. The major benefit was cited as enabling remote area clinicians to participate in multidisciplinary cancer meetings. Three of the 5 remote clinicians who practiced solely in the Northern Territory found that the telemedicine consultation increased their workload, while only 2 of 13 clinicians who practiced solely in South Australia reported an increase over their normal activities, the others reporting no difference. Benefits identified included better support of isolated clinicians, decreased travel, and enhanced education and peer review. Perceived difficulties were technical problems, the impersonal nature of the interaction, inability to examine the remote patient and lack of reimbursement for the consultation. Seven of the eight patients surveyed were satisfied or very satisfied with the telemedicine consultation. Four patients wished to have access to videotape of the multidisciplinary meeting. Of those requiring travel for treatment, all believed that the telemedicine consultation influenced their care and shortened their time away from home.

Change of patients' perceptions of TeleHomeCare.

The study's objectives were to measure patients' perceptions of a telehomecare system before and after they have participated in it and identify the features of the system that patients perceived differently after experiencing it. The study setting was the TeleHomeCare Project, which uses videoconferencing and Internet equipment to enable interactions between patients and nurses. An instrument that measures perceptions of telehomecare was used. Patients viewed a videotape that demonstrates a "virtual home care visit" and filled out the questionnaire (pre-test). They were then randomly assigned to a control group receiving standard care or to an experimental group receiving videoconferencing and Internet access in addition to standard care. Both groups filled out the questionnaire when exiting the system (post-test). Paired t-tests were performed to compare total scores and responses to each of the items within the groups and an unpaired t-test was used to compare change of perceptions between groups. The control group consisted of 11 patients, and the experimental group included 17 patients. There was no statistically significant change of perception in the control group. The experimental group showed an overall more positive perception of the system after their experience (total score increase by 6.059, p < 0.0001), and the mean score difference was higher compared to the control group (mean 6.241, p < 0.0001). Elderly patients evaluated their telehomecare experience as being positive, and they felt more comfortable with the technology, believing that the nurse can understand their medical problem over the television. This suggests that telehomecare has the potential for wide acceptance among patients.

Preliminary findings from a teleultrasound study in Alberta.

BACKGROUND AND OBJECTIVES: Ultrasound practice in Alberta requires direct supervision by an ultrasound-accredited specialist physician (sonologist). This requirement limits access to ultrasound examinations in many rural communities. A prospective study was performed to evaluate the adequacy of teleultrasound service in High Level, Alberta, with remote sonologist supervision from Edmonton, Alberta. METHODS: A total of 146 patients were evaluated in two groups. Group A (72 patients) was evaluated by both an on-site radiologist in High Level and a remote supervising radiologist in Edmonton. Group B (74 patients) was evaluated only by the remote supervising radiologist in Edmonton. The teleultrasound service included digital store-and-forward capabilities using a commercially available teleradiology system, with videoconferencing review for real-time scanning. RESULTS: The teleultrasound service was helpful to the referring physician. It made transfer unnecessary in 42% of patients, and the results of the ultrasound assessment influenced management in 59% of patients. The sonographer on site and the remote radiologists agreed on the quality of the images. The information required for diagnosis was available from the sonographer's study in the majority of cases, with second-look scanning by the on-site radiologist or videoconferencing by the remote radiologist providing a major new diagnosis in only 1% of patients. CONCLUSION: Teleultrasound service to High Level could be provided reliably with remote supervision, comparable to direct on-site supervision.

Telepsychiatry with child welfare families referred to a family service agency.

A telepsychology and telepsychiatry service, using ISDN interactive video H.320, providing psychological consultations for the Family Resource Center in Farmington, New Mexico, was evaluated. During the first year of service, 56 individuals participated including University of New Mexico staff, Family Resource Center staff and clients. Consultations involved children from families referred by the Children, Youth and Family Department (CYFD) in New Mexico. Telemedicine was used in some child abuse cases. This study investigated whether the quality and acceptance of telemedicine consultations were comparable to face-to-face interactions in a group referred by a state child welfare agency. Participants received formal written consultation reports after the video conferencing sessions, which included a number of recommendations. Participants were asked to complete an anonymous questionnaire to rate various aspects of videoconferencing. The participants rated the university staff as involved, enjoyed the Family Resource Center staff's presence, felt the procedure was useful for evaluation purposes, found the format allowed for discussions of problems, and felt that the format was useful when compared to face-to-face consultations. The participants also said they had followed up on many of the recommendations. Videoconferencing appears to be a viable approach for providing consultation for families referred by a state child welfare agency. Several participants rated the session as both educational and consultative compared to simply therapeutic.

Home telehealth improves clinical outcomes at lower cost for home healthcare.

Patient outcomes and cost were compared when home healthcare was delivered by telemedicine or by traditional means for patients receiving skilled nursing care at home. A randomized controlled trial was established using three groups. The first group, control group C, received traditional skilled nursing care at home. The second group, video intervention group V, received traditional skilled nursing care at home and virtual visits using videoconferencing technology. The third group, monitoring intervention group M, received traditional skilled nursing care at home, virtual visits using videoconferencing technology, and physiologic monitoring for their underlying chronic condition. Discharge to a higher level of care (hospital, nursing home) within 6 months of study participation was 42% for C subjects, 21% for V subjects, and 15% for M subjects. There was no difference in mortality between the groups. Morbidity, as evaluated by changes in the knowledge, behavior and status scales of the Omaha Assessment Tool, showed no differences between groups except for increased scores for activities of daily living at study discharge in the V and M groups. The average visit costs were $48.27 for face-to-face home visits, $22.11 for average virtual visits (video group), and $32.06 and $38.62 for average monitoring group visits for congestive heart failure and chronic obstructive pulmonary disease subjects, respectively. This study has demonstrated that virtual visits between a skilled home healthcare nurse and chronically ill patients at home can improve patient outcome at lower cost than traditional skilled face-to-face home healthcare visits.

Telerehabilitation support for families at home caring for individuals in prolonged states of reduced consciousness.

OBJECTIVE: To investigate the use of telerehabilitation to support families caring at home for individuals with prolonged states of reduced consciousness. DESIGN: A comparison group approach. PARTICIPANTS: Participants were recruited from a special program that is part of a Model Systems brain injury program located in the Southeast. Five patients, ranging from Rancho 1 to Rancho 3 were discharged home with family members as the primary caregivers. PROCEDURES: Participant families were followed for 4 to 8 weeks via videophone. Follow-up telephone surveys were conducted with a family member 6 to 9 months after discharge and compared with a similar group that had not received the videophone follow-up. MAIN OUTCOME MEASURES: Present living status, number of emergency room visits, number of hospitalizations, the caregivers' perceptions of functional status and care needs, readmission for rehabilitation and perceived family needs as measured by the Family Needs Questionnaire (FNQ). RESULTS: More patients in the videoconferencing group were still living at home and had returned for rehabilitation. On the FNQ, families in the videophone group reported more of their needs met than families in the comparison group. CONCLUSIONS: The use of videoconferencing to bridge the transition to home for families caring for a family member at the Rancho 1 to Rancho 3 level may assist families in successfully caring for the individual in the home and reducing the number of perceived family needs.

Student perspectives on transitioning to new technologies for distance learning.

This article reports on students' perceptions of their learning experiences when an existing distance-learning master's program transitions to new technologies and new instructional strategies. Unique elements addressed in this article include (1) findings when a program with extensive experience delivering distance education changes to new technologies and (2) findings when a multidimensional format is used to evaluate program delivery. The technology changes involved migrating from a satellite-based technician-supported videoconferencing system to a land-based faculty-operated videoconferencing system and the addition of class Web materials and asynchronous computer conferencing to course delivery. The multidimensional evaluation format examined student experiences within the context of specific interactions among instructional activities, technology applications, and desired learning outcomes. The evaluation process involved (1) open-ended and structured items in course surveys and (2) an end-of-year student focus group discussion. A formative evaluation approach was used; this article reports on efforts to address the problems identified. Findings include (1) program planners should not assume that prior institutional experiences with distance education facilitate a smooth transition to use of different technologies and (2) a formative multidimensional approach to program evaluation is critical for understanding student experiences with technology-mediated distance education.

A new approach to teleconferencing with intravascular US and cardiac angiography in a low-bandwidth environment.

A common problem in radiology teleconferencing is the difficulty of transmitting a large volume of data over communication channels with a relatively low bandwidth. Although videoconferencing systems are easily implemented, they generally require lossy image compression, which can lead to significantly altered findings. A teleconsultation and teleconferencing system was developed that uses a store-and-forward approach with high-quality dynamic medical images obtained with intravascular ultrasonography and cardiac angiography. The system allows use of high-resolution dynamic images while preserving their original quality and can be adapted to different clinical applications with varying requirements. The system involves a standard preparation procedure to transmit images from one location to another prior to a conference; once the conference starts, however, the system becomes fully automatic and synchronizes the display and manipulation of images in both locations without further image data transmission. In general radiologic applications, the system is superior to videoconferencing systems in that it does not require specialized hardware and dedicated high-bandwidth communication links. Further investigation with large-scale studies will be required to determine whether these benefits can lead to more widespread acceptance of such a system in routine clinical practice and whether teleconferencing itself can enhance the effectiveness of clinical procedures.

Can telehealth technology be used for the education of health professionals?

The purpose of this report is to describe the usefulness and desirability of using telehealth technology in the education of health care professionals. The PC-compatible, Windows-based system allowed for both real-time videoconferencing and store-and-forward (sending information from one site and stored at a distant site for access at a later time) functions. Student responses indicated that they thought they would benefit from this type of technology in their clinical education. They were most positive with respect to increasing access to a wider range of clients they may not otherwise access and least positive for the ability to learn from a televideo interaction when compared with a clinic experience. Similarly, faculty were least interested in using videoconferencing for patient rounds and more interested in using telehealth to enhance classroom presentations.

Using telemedicine for distance education.

We assessed the use of videoconferencing as an educational tool for students and emergency nurse practitioners based at a minor injuries unit. Nineteen teaching sessions were conducted by videoconferencing, followed by a debriefing session in which the participants made observations about their educational experience. The participants observed that the experience was rewarding. The success of the teaching session depended on group size: an upper limit of six is recommended. The teaching sessions encouraged debate, independent thinking and peer communication.
