Applicability of telemedicine for assessing patients with schizophrenia: acceptance and reliability.

BACKGROUND: Telemedicine holds promise for providing expert psychiatric consultation to underserved populations, but has not been quantitatively studied in schizophrenia or any other major mental disorder. This study was conducted to assess the reliability and acceptance of video-conferencing equipment in the assessment of patients with schizophrenia. METHOD: We assessed reliability of the Brief Psychiatric Rating Scale (BPRS), Scale for the Assessment of Positive Symptoms (SAPS), and Scale for the Assessment of Negative Symptoms (SANS) under three conditions: (1) in person, (2) by videoconferencing at low (128 kilobits per second [kbs]) bandwidth, (3) by videoconferencing at high (384 kbs) bandwidth. All 45 patients met DSM-IV criteria for schizophrenia. All patients and the two interviewers rated various aspects of the study interviews against previous live psychiatric interviews. RESULTS: Total scores on both the BPRS and SAPS were assessed equally reliably by the three media. Total score on the SANS was less reliably assessed at the low bandwidth, as were several specific negative symptoms of schizophrenia that depend heavily on nonverbal cues. Video interviews were well accepted by patients in both groups, although patients in the high bandwidth group were more likely to prefer the video interview to a live interview. CONCLUSION: Global severity of schizophrenia and overall severity of positive symptoms were reliably assessed by videoconferencing technology. Higher bandwidth resulted in more reliable assessment of negative symptoms and was preferred over low bandwidth, although patients' and raters' acceptance of video was good in both conditions. Videoconsultation appears to be a reliable method of assessing schizophrenic patients in remote locations who have limited access to expert consultation.

A new method for surgical consultations with videoconference.

BACKGROUND: The aim of our prospective study was to examine the technical ability and the medical suitability of a realtime teleconferencing system in surgical consultations. METHOD: A personal computer-based-videoconferencing system was used over an architecture of the IP (Internet Protocol) over ATM (Asynchronous Transfer Mode) area network connecting Satakunta Central Hospital, Pori with a health center in the community of Noormarkku (15 km apart from Pori). A document camera was used for transfering the radiographs and paper documents. The material consisted of 50 patients who needed surgical consultation. The patients were examined by a physician in the health center of Noormarkku, and the surgeon interviewed and observed the physical examination with the aid of teleconference. RESULTS: Technically the videoconferencing system functioned reliably, and the visual quality of the videopicture was good after more powerful personal computers (Pentium II with a 266 MHz prosessor and 64 Megabits RAM-memory) were changed for the videoconferencing system. All patients, except one, saved the travelling to the face-to-face appointment because they got a definite decision of the treatment already at the videoconsultation. According to the opinion of the consulting surgeon, the decision which was made in the teleconference was good or very good, except in one case very poor. The physicians of the health centers were satisfied both with the decisions of the treatment of their patients and with the educational effect of a consultation where two physicians are present at the same time. All patients thought that it was good to be in consultation with two doctors. CONCLUSION: Surgical videoconsultations are a reliable method and a real alternative to sending a patient to a distant place for consultation.

The clinical achievements of a geriatric telehealth project in its first year.

We performed a feasibility study to test the validity of conducting two standard cognitive assessments via videoconferencing. There was a high correlation between the scores from a face-to-face assessment and those from a videoconference. A second trial was conducted with patients living in a rural community, examined both face to face and via videoconferencing. Again, the validity and reliability of the assessment tools were demonstrated for videoconferencing. The acceptability of the technology to patients and clinicians was also shown. As a result of the trials and at the request of rural participants, geriatric telehealth services are now being provided to a rural aged care assessment team (ACAT) on a fee-for-service basis. The success of this project is reflected in its senior clinical and academic 'champions', the establishment of a dedicated telehealth resource and the development of protocols.

Telerehabilitation consultations for clients with neurologic diagnoses: cases from rural Minnesota and American Samoa.

Telerehabilitation is the provision of rehabilitation services at a distance using electronic information and communication technologies. This paper describes two clinical programs that utilize videoconferencing to provide rehabilitation specialist consultations to individuals living in remote areas. Needs assessments for the two areas revealed that local clinicians were interested in access to specialty consultation. Administrative processes and a data collection tool were developed for these programs. High speed videoconferencing that allows for real-time audio and video interaction was used. Each consultation includes the patient, the local caregivers and specialists from our facilities interacting via videoconferencing. A total of 117 telerehabilitation encounters have been completed. All consultations resulted in changes to the plan of care. Clinicians who participated in the projects consistently rated the clinical effectiveness of teleconsults as good or excellent. Thirty-eight consultations have been neurologic in nature. Of that set, 25 of the visits were initial assessments, and thirteen were follow-up visits. Two case studies of individuals with neurologic diagnoses are presented. Recommendations to others who are providing rehabilitation services via telehealth technologies are included. The authors conclude that the care of individuals with neurologic issues can be augmented and supported via specialty consultation using telehealth technology.

Seven years of clinical experience with teleconsultation in craniomaxillofacial surgery.

PURPOSE: In this work the experiences from 50 telemedically supported treatments in craniomaxillofacial surgery are summarized and different setups for their technical realization are described. Furthermore, for the first time the innovative UMTS (universal mobile telecommunication system) is applied for the transmission of arthroscopic videos of the temporomandibular joint and other craniomaxillofacial structures. MATERIALS AND METHODS: The combination of computer-assisted navigation technology in augmented reality environments with telecommunication is used for execution of interactive stereotaxic teleconsultation. Furthermore, treatments without navigation are telemedically supported. This study is composed of 4 technical system configurations: 1) integrated services digital network (ISDN)-based videoconferencing without remote control of the navigation computer; 2) transmission control protocol/internet protocol (TCP/IP)-based interactive teleconsultation via bundled ISDN lines (including remote control of the navigation computer); 3) TCP/IP-based interactive teleconsultation via network; 4) combination of TCP/IP-connection and ISDN-based videoconferencing. The telemedically supported treatments are: orbitozygomatic osteotomies, positioning of the mandibular condyle in orthognathic surgery, insertion of implants, positioning of the maxilla in orthognathic surgery, distraction osteogenesis, arthroscopies of the temporomandibular joint, and operation simulations on stereolithographic models. The surgical interventions are evaluated on a 5-level system performance scale from the technical point of view. In a separate trial 20 videosequences of arthroscopies of the temporomandibular joint are transmitted via UMTS cellular phones and independently evaluated by 3 experts (ie, a total of 60 streamings) to investigate feasibility of this technology in the field of craniomaxillofacial surgery. RESULTS: In the years from 1996 to 2002 a total of 50 treatments were telemedically supported. All intraoperative applications were successfully finished; 48 of 60 UMTS transmissions were finished without any interruptions in constant quality, slight interruptions were observed in 8 tests, and a complete breakdown was observed during 4 streamings that required a restart of the transmission. Resolution was sufficient to diagnose even tiny anatomic structures inside the temporomandibular joint, but orientation was hardly recognizable. CONCLUSION: In many applications telecommunication technology can contribute to a quality improvement in cranio- and maxillofacial surgery because of the global availability of specialized knowledge. The required technical expenditure for teleconsultation crucially depends on the infrastructure that is already available at the clinic and the remote site. UMTS is a promising technology with the potential to be valuable in numerous craniomaxillofacial applications.

Behavioral health care of isolated military personnel by videoconference.

The changing role of the military presents a unique challenge for military behavioral health organizations in dealing with the geographic isolation of personnel. Telemedical solutions should help to meet this challenge. In the behavioral health arena, there are many uses for videoconferencing and other communications technology in maintaining continuity when patients or clinicians travel or deploy; assisting isolated behavioral health-care providers and general practitioners; evaluating and treating isolated military personnel; and addressing family issues. Family interventions by videoconference and other communications technology may be particularly useful in treating military personnel and in promoting morale of the fighting force. Although much remains to be researched and proven empirically, anecdotal experience supports the utility of using communications technology to enhance behavioral health interventions. This article describes the clinical videoconference experience within the Department of Psychiatry at Tripler Army Medical Center (TAMC), during a Multinational force deployment to the Sinai, and during training at the Joint Readiness Training Center, Fort Polk, Louisiana. A brief discussion of potential legal issues involving videoconferencing in behavioral health is also included.

Group tele-exercise for improving balance in elders.

This study was to assess the level of acceptance and efficacy of a group tele-exercise program designed for balance impaired elders to improve balance and reduce fear of falling. The program would allow a group of elderly subjects to participate in a structured, interactive, and supervised exercise class from their own homes through a videoconferencing system. A total of 17 independent living elderly subjects (mean age, 81 +/- 8 years) participated in the study. An Internet-based videoconferencing device (VCD) was installed in each subject's home, allowing real-time video and audio communication with the exercise instructor and all other participants. The exercise was in the form of Tai Chi Quan, three times per week for 15 weeks. The main study measures included exercise compliance, level of acceptance and satisfaction, and the effectiveness of the exercise program on balance, fear of falling, and general health. Three subjects dropped out of the study. For those remaining, the average compliance was 78% (range, 51% to 98%). All subjects were able to operate the VCD independently, and expressed earnest interest in continuing tele-exercise programs in the future. There were significant improvement (p < 0.05) postexercise in fear of falling score (18%), single leg stance time (43%), Up-and-Go time (21%), and body sway during quiet stance (>8%). This study has demonstrated that the group tele-exercise program is acceptable and welcomed by elders, and is effective for improving balance and reducing fear of falling.

The use of telemedicine in psychiatry.

This paper examines the potential effects of using video-conferencing within the field of mental health in the UK. In order to assess the usefulness of telepsychiatric services, an electronic search was conducted for articles published between August 1998 and July 2006 using the MEDLINE, EMBASE, PsychINFO and Telemedicine and Information Exchange (TIE) databases. The search was carried out using the following terms: telepsychiatry, videoconferencing and telepsychology. A total of 178 articles were identified and based on review of the abstracts 72 were identified as being specific to efficacy, cost-effectiveness and satisfaction with psychiatric services delivered via videoconferencing. This paper concludes that the use of video conferencing can enhance psychiatric services within the UK especially for those patients who live in rural areas. Current advances in technology make this an increasingly more reliable and cost-effective method for assessing patients. The limitations of telemedicine are discussed and it is clear that this type of care is not suitable for all patients. Further research is required to assess the types of patients that telepsychiatry is most suitable for.

Virtual TeleStroke support for the emergency department evaluation of acute stroke.

OBJECTIVES: Telemedicine-enabled acute stroke consultation (TeleStroke) may be useful to determine eligibility for treatment with tissue plasminogen activator (tPA) and provide support to emergency departments without on-site stroke expertise. METHODS: Emergency physicians consulted with stroke neurologists via two-way videoconferencing in the evaluation of patients with possible acute stroke. History, neurologic examination, and computed tomography of the head were reviewed to determine eligibility for treatment with tPA. Interpretations of computed tomography were compared for inter-rater reliability between the neurologist and the neuroradiologist using a conventional workstation. Videotape and written records were analyzed to determine time intervals, patient management, and user satisfaction. RESULTS: The authors reviewed data from 24 patients evaluated over 27 months at an island-based hospital. The mean National Institutes of Health Stroke Scale score was 5.7 (range, 0-22). Fifteen patients arrived at the emergency department less than three hours after symptom onset; 12 were presented for TeleStroke consultation within three hours after symptom onset. Eight of these 12 (75%) had acute ischemic stroke, and six of these eight potentially eligible patients (75%) received intravenous tPA. There was very good agreement among all remote readers for detecting the one case of imaging exclusion (subdural hemorrhage). There were no protocol violations, and a mean (+/- SD) consult-to-needle time of 36 (+/- 15) minutes and door-to-needle time of 106 (+/- 22) minutes was achieved. Transfer was avoided in 11 patients. Physicians believed that TeleStroke consultation improved care in >95% of the cases. CONCLUSIONS: TeleStroke videoconferencing can support emergency department-based evaluation of acute stroke and may facilitate tPA delivery in neurologically underserved facilities. A prospective, randomized trial is needed to determine if these systems are superior to traditional telephone consultation.

In-service nursing education delivered by videoconference.

Thirty nursing auxiliaries at a Brazilian hospital were trained in intramuscular injection at the ventrogluteal site in a lecture delivered by videoconference (over an IP connection at up to 512 kbit/s). Participants were able thereafter to practise on the same manikins used for demonstration during the lecture, until they felt confident in carrying out the procedure. They then completed an evaluation questionnaire on the use of videoconferencing as a teaching method. Most of their responses were favourable. The principal reasons given for attending the videoconference lecture were the ability to combine work and education, the opportunity to participate in an innovative approach and an interest in the subject of the lecture. The present study demonstrates the potential of videoconferencing for distance education in nursing.

Videoconferences for rural physicians' continuing health education.

The University of Alberta uses videoconferencing to link physicians in interactive continuing health education. We examined evaluations of 29 videoconferences for rural practitioners during the programme year September 2003-May 2004. The evaluation form, completed by participants following the presentation, used both quantitative and qualitative methods of data collection. The average attendance for the videoconference sessions was 40 people. A total of 593 evaluations were collected (response rate 51%). The audience were very satisfied with the programme and felt that the sessions were relevant to their practice. The interactive discussion component was rated very highly. Most respondents stated that they would change their practice based on the information discussed. It is clear from our survey that videoconferencing is useful in overcoming the barriers of distance and that small physician numbers create a positive environment for adult learning.

Telemedicine in haemodialysis: a university department and two remote satellites linked together as one common workplace.

A common workplace was established between the renal unit at the University Hospital of North Norway and two satellite dialysis centres, in Alta and Hammerfest. A 2 Mbit/s ATM network was employed for IP-based videoconferencing. A common electronic medical record system and dialysis monitoring software were used. During an eight-month study period, nine patients were enrolled and 225 videoconferences were performed for daily visits and regular rounds. A bandwidth of 768 kbit/s was required for satisfactory teledialysis. Although technical (28%) and logistical problems (10%) were frequent, five hospitalizations and one-third of the planned visiting rounds were avoided. An economic analysis showed that annual savings amounted to US$46,613, while annual costs were US$79,489. Despite the technical difficulties in about 30% of conferences, the nurses were satisfied with the videoconferencing system. Digital X-rays were communicated without problems. The pilot study indicates that satellite units may be incorporated into the daily management at the central institution by telemedicine.

Telemedicine for delivery of health care in Parkinson's disease.

We have used telemedicine at the Seattle Veterans Administration Medical Center to deliver follow-up care to patients with Parkinson's disease (PD). Patients were located at eight facilities which were 67-2400 km from the medical centre. Each facility had videoconferencing equipment (connected by Internet Protocol at 384 kbit/s), and computer terminals that could access the patient's electronic medical record. Over a three-year period, we used telemedicine for 100 follow-up visits on 34 PD patients. Visits lasted 30-60 min. Patients and providers were satisfied with the use of the technology. Savings amounted to approximately 1500 attendant travel hours, 100,000 travel kilometres, and US 37,000 dollars in travel and lodging costs. For the first 82 telemedicine visits, the video quality was inadequate for scoring all components of the motor Unified Parkinson Disease Rating Scale (UPDRS). For the last 18 visits, a different videoconferencing unit produced better video quality, which was satisfactory for motor UPDRS measurements, except for components that required physical contact with the patient (rigidity and retropulsion testing). Our experience shows that telemedicine can be used effectively for follow-up visits with selected PD patients who are unable to travel.

How to do a telemedical consultation.

In a telemedical consultation, medical information is sought at a distance. Two techniques may be used: asynchronous ('store and forward') and synchronous ('realtime'). Asynchronous consultations have the advantage that the two parties do not have to be available simultaneously; email, for example, has been used successfully for teledermatology. Synchronous consultations depend on communication media such as the telephone, radio or videoconferencing. Successful videoconferencing will involve consideration of four factors: the environment, session initiation, dialogue and session closure. The environment is very important for good-quality consultations and involves planning, equipment and training. Recognizing the advantages and limitations of the available media combined with appropriate planning and training will maximize the utilization of teleconsultations.

Telepsychiatry improves paediatric behavioural health care in rural communities.

In the US, children with special health care needs are underserved by both the medical and educational systems. This problem is especially serious in rural states. Telemedicine is a technique that can reduce these gaps in service and help connect the two systems. The technology required has become cheaper and more accessible. Progress on reimbursement for such services has also been made. For some years, we have provided telepsychiatry for children in Washington State using videoconferencing. Interviews with families and service providers were conducted in Washington and Missouri. Some parents reported that their child actually preferred telepsychiatry to conventional consultation. The telepsychiatry service model was built on the existing system of outreach clinics, thus involving specialists who were familiar with the community and who were known and trusted by the community. Before starting, we ensured that all relevant service delivery agencies and providers were comfortable about using videoconferencing as a method of service delivery. In the 18-month period ending in March 2003, three providers in Seattle saw 159 patients by telepsychiatry and 210 patients face-to-face at the hospital clinic. The main barrier to further growth of the telepsychiatry service is the absence of reimbursement for telepsychiatry.

Telepsychiatry in psychogeriatric service: a pilot study.

A pilot study on telepsychiatry was conducted in which a videoconferencing link was established between a regional hospital and a care and attention home. Using this system, a psychogeriatric outreach team provided 149 psychiatric assessments to 45 residents of the care and attention home over 11 months. Videoconferencing was found to be highly feasible. It was acceptable to staff and patients and more cost-effective than on-site visits.

[Telecommunication in trauma surgery. Communication networks of hospitals in East Bavaria].

The growing complexity of the performance processes in medicine makes it mandatory that the flow of information is faster and more consistent, especially when the sites of health care are far away from each other. The Regensburg model, a realization of lean telemedicine from a low-cost domain, using PC-based standard videoconferencing systems shows the use of modern telecommunications, especially in trauma surgery. In 203 prospectively evaluated teleconsultations between 15 participants a total of 697 images were transmitted via videoconferencing. In 95% of the trauma cases the transmitted material was judged as at least sufficient. In project-attending evaluations the efficacy of these systems and their use were clearly demonstrated. Savings in transportation costs of up to 4,400 DM per case were achieved. Through quicker flow of information quality improvements for all participants resulted; to some extent considerable costs for health care were avoided or reduced. Based on these thoughts, a new platform of communication will be established in Regensburg as a closed medical intranet for the region of eastern Bavaria.
