We evaluated user satisfaction with a PC-based videoconferencing system used for child psychiatry assessments and performed a cost analysis. Thirty patients (aged 5-16 years), accompanied by a parent, completed a psychiatric assessment using the videoconferencing system. One of five child psychiatrists was randomly assigned to each assessment. Satisfaction questionnaires were completed after each assessment by the psychiatrist, patient and parent. Parents also completed a cost questionnaire. The telecommunications bandwidth was 336 kbit/s. The psychiatrists stated that they were either 'very satisfied' or 'satisfied' with the telepsychiatry assessments. On a five-point Likert scale (1 = lowest, 5 = highest), 28 of the 30 parents (93%) rated their satisfaction level as 5; the other two rated it 4. All 30 parents (100%) stated that they 'liked' the telepsychiatry assessment and would use the system again. Twenty-nine parents (97%) indicated that they would prefer to use the telepsychiatry system to travelling to see a child psychiatrist in person. Eleven children (aged 5-12) participated and all (100%) said they 'liked' using the telepsychiatry system. Five out of nine children (56%) stated they liked the 'television doctor' better than the 'real' doctor; four said they had no preference. Nineteen adolescents (aged 13-16 years) participated and most were very satisfied or satisfied with the system. Seventeen of the 19 adolescents (89%) said they would prefer to see the psychiatrist on the videoconferencing system to travelling for an assessment, and the same number said that they would use telepsychiatry again. The estimated total travel cost for the 30 patients was $12,849, an average of $428 per patient. The total cost of the telepsychiatry service for the three-month pilot was $12,575, or $419 per patient.

We examined all articles describing video applications of telemedicine for psychiatry (i.e., "telepsychiatry") that have been published in peer-reviewed journals. We found three reports of video application to continuing education, eight uncontrolled studies or anecdotal clinical reports of video application to assessment or consultation, five clinical investigations including a control group or control condition, three studies evaluating the reliability of administering psychological rating scales by video, and two studies of the cost-effectiveness of telepsychiatry. Although the conclusions of all studies reviewed recommended the use of telepsychiatry, evidence currently available is insufficient to suggest its widespread implementation. Additional studies are needed to determine when and for what age groups and conditions telepsychiatry is an effective way to deliver psychiatric services, and whether it is cost-effective. We recommend that telepsychiatry be employed on a limited basis and be restricted to research settings and underserved communities (where it may be the only option) until further evidence is available.

The University Hospital of Tromsø has been involved in a variety of telemedicine activities since the late 1980s, including teleradiology, telepathology, teledermatology, remote endoscopy, remote gastroscopy, teleechocardiography, transmission of electrocardiograms, telepsychiatry, electronic delivery of laboratory results and distance learning for health professionals. Since 1993 the department of telemedicine in Tromsø has been designated the national centre of competence in telemedicine. With a wealth of experience to draw from, a critical number of health-care professionals exposed to and using telemedicine routinely, the support of the Norwegian health authoriues, a national centre guiding telemedicine research, no licensing barriers within the country, nationwide ISDN and reimbursement for telemedicine services, the future of telemedicine in Norway looks promising.
