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.

Patient and physician satisfaction with a telephone-based anticoagulation service.

OBJECTIVES: To compare the satisfaction and knowledge of patients who have their warfarin managed by their physician or by a multidisciplinary, telephone-based anticoagulation service (ACS) and to assess referring physicians' satisfaction with the ACS. DESIGN AND PARTICIPANTS: We surveyed 300 patients taking warfarin (mean age 73 years): 150 at health centers randomized to have access to an ACS, and 150 at control health centers without ACS access. We also surveyed 17 physicians who refer patients to the ACS. SETTING: Eight outpatient health centers in Missouri and Southern Illinois. MEASUREMENTS: We asked patients about the timeliness of international normalized ratio (INR) monitoring, perceived safety of warfarin, overall satisfaction with their warfarin management, and knowledge of what a high INR meant. We asked physicians at ACS-available health centers how many minutes they saved per INR by referring patients to the ACS, their satisfaction with the ACS, and their willingness to recommend the ACS to a colleague. MAIN RESULTS: As compared with patients at control health centers, patients at ACS-available health centers were more satisfied with the timeliness of getting blood test results (mean 4.31 vs 4.03, P =.02), were more likely to know what a safe INR value was (45% vs 15%, P =.001), and felt safer taking warfarin (mean 5.7 vs 5.2, P =.04). Physicians reported that using the ACS saved, on average, four minutes of their time and 13 minutes of their staff's time, per INR. All physicians recommended use of the ACS to a colleague and were highly satisfied with the ACS. CONCLUSIONS: A telephone-based ACS can be endorsed by primary-care physicians and improve patients' satisfaction with and knowledge about their antithrombotic therapy.

Fluctuations in service loads in an established telemedicine program.

The goal of this investigation was to determine if there were identifiable patterns in the volume and types of teleconsults provided by an established telemedicine program over an extended period of time. Data from over 3 years of providing telemedicine consults within a university-based telemedicine programs were analyzed to identify trends and points of significant change in service provision. Teleconsult volume over a 40-month period was best fit by a logarithmic transformation of the regression curve that is characteristic of slow but steady growth. Consults have been provided in 53 subspecialties, with an average of 12 different subspecialties each month. Number of subspecialties per month was best fit by a sixth-order polynomial. Teleconsult volume has varied on a monthly basis, but overall volume has increased over time. This program has maintained its initial goal of being a multispecialty provider. Analyzing telemedicine consult data over extended periods of time is especially useful for long-term program evaluation and development of a successful business plan.

Teledermatology's impact on time to intervention among referrals to a dermatology consult service.

The aim of this study was to determine if a teledermatology consult system, using store-and-forward digital imaging technology, results in patients achieving a shorter time from referral date to date of initial definitive intervention when compared to a traditional referral process. Patients being referred to the dermatology consult service from the primary care clinics at the Durham VA Medical Center were randomized to either a teledermatology consultation or usual care. A usual care consultation consisted of a text-based electronic consult request. A teledermatology consultation included digital images and a standardized history, in addition to the text-based electronic consult. Time to initial definitive intervention was defined as the time between referral date and the date the patient was scheduled for a clinic visit for those patients that the consultant requested a clinic-based evaluation, or the time between referral date and the date the consult was answered by the consultant if a clinic visit was not required. Patients in the teledermatology arm of the study reached a time to initial definitive intervention significantly sooner than did those patients randomized to usual care (median 41 days versus 127 days, p = 0.0001, log-rank test). Additionally, 18.5% of patients in the teledermatology arm avoided the need for a dermatology clinic-based visit compared to zero patients avoiding a dermatology clinic visit in the usual care arm of the study (p < 0.001, z-test). Teledermatology consult systems can result in significantly shorter times to initial definitive intervention for patients compared to traditional consult modalities, and, in some cases, the need for a clinic-based visit can be avoided.

An audit of the appropriateness of teletriage nursing advice.

This study assessed the appropriateness of advice given by teletriage nurses to patients in northern Ontario. Assessments used audiotapes and printed records of 73 calls, selected from approximately 350 calls based on sound quality, completeness, and consent of caller and teletriage nurse. Audits were conducted independently by one family physician, one nurse practitioner, and one registered nurse with teletriage experience. In 56% of the 73 calls, all three auditors judged the nurse's advice as "appropriate." In 92% of the 73 calls, at least two of the three auditors judged the teletriage nurse's advice as "appropriate." All calls were rated as "appropriate" by at least one auditor. If not "appropriate," then auditors were three times more likely to rate the advice as "overly-cautious" rather than "insufficient." The percentage of calls with the same rating varied from 62% to 86% with an outlier of 33%. Nurse practitioners tended to rate the appropriateness of the advice slightly, but significantly lower than the rating given by family physicians or registered nurses. Interestingly, nurse practitioners tended to rate aspects of the nurse-caller interaction advice as slightly and significantly better than the rating chosen by family physicians or registered nurses. The teletriage service was providing appropriate advice, but the generalizability of these results may be limited because of the selection of calls.

Telemedicine in laryngology.

OBJECTIVE: The significance and usefulness of image transmission in laryngology were evaluated retrospectively on the basis of daily clinical practice. MATERIALS AND METHODS: The subjects consisted of 29 patients with laryngeal disease, whose laryngeal findings had been already recorded on videotape. Patient data were sent to a major hospital by Internet e-mail. Two laryngeal images, during breathing at rest and phonation, were transmitted as an attached file. Using a rigid or flexible endoscope coupled with a one-chip CCD camera, laryngeal images were recorded. Pictures of these laryngeal images were printed by a video printer, digitized by a compact print scanner, and saved as JPEG files. RESULTS: The diagnosis made by the three specialists in laryngology (receivers), who referred to the transmitted images and text files of the patient's history, was identical to the diagnosis made by the general otolaryngologist (sender), who referred to the original pictures and patient data. All images were displayed with sufficient quality to evaluate morphologic abnormalities, and the disturbance of cordal movements was detectable by comparing images during breathing at rest with those obtained during phonation. CONCLUSION: The image-transmitting system was a useful tool for consultation between otolaryngologists and for referrals from general practitioners to otolaryngologists.

Patient and clinician satisfaction with a store-and-forward teledermatology consult system.

The aim of this study was to assess satisfaction with and acceptance of a store and forward teledermatology consult system among patients, referring primary-care clinicians, and consultant dermatologists. As part of a randomized clinical trial that compared the clinical and economic outcomes of store and forward teledermatology to a conventional referral process, we conducted satisfaction assessments among participating patients, referring primary-care clinicians, and consultant dermatologists. Survey questions included issues related to the timeliness of each consult process, the confidence participants displayed in each consult modality, and assessments of overall satisfaction and preferences. A majority of referring clinicians (92%) and dermatologist consultants (75%) reported overall satisfaction with the teledermatology consult process. Ninety-five percent of referring clinicians reported that teledermatology resulted in more timely referrals for their patients. This finding was validated by the observation that teledermatology patients reached a point of initial intervention significantly sooner than did patients in usual care (41 days versus 127 days, p = 0.0001). Teledermatology patients reported satisfaction with the outcome of their teledermatology consultation 82% of the time. However, patients did not express a clear preference for a consult method. A total of 41.5% of patients preferred teledermatology, 36.5% preferred usual care, and 22% were neutral. Our study showed a high level of satisfaction among all users of a store-and-forward teledermatology consult system, and, in some cases, our survey results could be validated with observed clinical outcomes.

NHS Direct derived data: an exciting new opportunity or an epidemiological headache?

NHS Direct, a national telephone helpline for health advice, was established in 1998 to provide health information and advice to callers and refer them to an appropriate service. This article briefly describes the nature of the NHS Direct call record and discusses issues relevant to the use of the data for disease surveillance and epidemiological purposes. Clinical decision support software [the NHS Clinical Assessment System (NHS CAS)] is used by NHS Direct to collect callers' demographic details and direct them to the appropriate level of care. Data relating to NHS Direct calls provide a timely snapshot of symptoms occurring in the community and are summarized in 'off the shelf' NHS CAS reports. Adapting the system to provide customized data extracts requires considerable development work. When interpreting NHS Direct derived data, particular attention should be given to the age distribution of callers, NHS Direct demand surges, call 'networking' and changes to the NHS CAS clinical algorithms. An increasingly rich source of baseline data, growing body of published work, and a more 'bedded down' NHS Direct service will further our understanding and acceptance of the value of the NHS Direct call record.

RheumaNet--a novel Internet-based rheumatology information network in Germany.

Knowledge transfer in medicine has traditionally been achieved through personal communication, the medical literature, conferences and continuous medical education. However, many of these methods of communication have the problem of currentness, and the latest knowledge is mostly transferred with a certain delay. In particular, chronic disease management is frequently burdened by missing, incomplete or delayed communication. We present the implementation of a novel, Internet-based information system (RheumaNet) to facilitate rapid communication and information transfer between the 21 German Multipurpose Arthritis Centres (MACs). Medical information, agendas, urgent notifications, guidelines, etc., can be exchanged easily via electronic mail, file transfer protocol or the World Wide Web. RheumaNet allows interactive on-line communication as a common platform for joint projects or remote consultation. It supports a set of 'core documentation' that has been used by all German MACs for several years. RheumaNet was used for the organization, on-line presentation and evaluation of the 1997 annual meeting of the German Rheumatology Society and is currently appointed to establish its public representation in the 'Web'. An on-line version of the 'Quality Assurance Textbook' of German rheumatology is achieved with database-derived 'dynamic' Web pages, allowing easy access to any information within it. Advances in the future include the development of on-line patient information bulletin boards, on-line questionnaires, the coordination of rehabilitation and educational tools for medical students, and professional training.

Development of a universal connectivity and data management system.

Point-of-care testing (POCT) is an increasingly popular method of delivering laboratory testing. Management of POCT is challenging given the variety of devices, locations, and staff that need to be coordinated to ensure quality results and meet regulatory guidelines. Electronic capture and transfer of data are preferred for managing POCT, but there is currently no standard method of connecting different devices. Johns Hopkins Medical Institutions (JHMI) developed a common data management system with interfaces to all of its POCT devices. All POCT data are collected in one database and analyzed in a similar fashion. Where data were once collected by carrying laptops to each nursing unit, the POCT devices can now connect directly to the database over the Internet. Algorithms have been created to automate the data analysis and review process. Over the several years that this software has been used, JHMI has experienced improved quality, accuracy, and management of its POCT program. The labor saved by increased automation of data review is refocused on enhancing the performance and scope of the program. Current connectivity and analysis algorithms have future application to remote consultation, management of home self-monitoring patients, and examination of real-time data.

Telephone triage. The rules are changing.

The pressures of increasing clinical practice productivity as well as the limitations on parents' ability to make pediatric office visits has made it more difficult for children to be seen emergently in primary care clinics. For many children this translates into visiting an acute care center or emergency room to have urgent care needs quickly assessed and treated. Because of the gatekeeping now imposed on many organizations, it has become necessary for many primary care office settings to develop telephone management systems to triage the acuity of office visits or emergency room needs. This article reviews the issues inherent in developing an office-based telephone triage system, demonstrates some legal guidelines to follow for documentation, and describes the process of emergent management of parental concerns about child health.

Information technology, the internet, and the future of neurology.

BACKGROUND: This review addresses the impact of information technology and the Internet on the current and future practice of neurology. Information technology is influencing medical practice in ways that could be both beneficial and harmful. Scenarios are presented to depict some of the ways in which the practice of neurology is being influenced by the growth of technology. REVIEW SUMMARY: First, the advantages and disadvantages of e-mail as a means of doctor-patient communication are presented. Some of the ethical and legal issues arising in this context are discussed.Second, the Internet is changing neurologists' relationships to other professionals in the health care industry. Geographical isolation is less problematic than in the past. Telemedicine, including remote consulting via the Web, has special implications for neurologists in several areas, including stroke management, movement disorders, and epilepsy.Third, the growing availability of large databases, powerful search engines, and online full-text journals is discussed. Skill in navigating and managing these resources will become increasingly important. New computer-assisted decision support systems will continue to be implemented. Applications exist or are being developed for use by clinicians for many specific neurologic disorders.Finally, some of the problematic issues concerning medical use of the Internet are discussed, including availability, portability, security, quality, and outcomes. CONCLUSIONS: Medical information systems, with their attendant advantages and limitations, will become increasingly significant in the practice of neurology. Despite overall improvement in access to information, major barriers still exist to the proper implementation and utilization of truly integrated information systems.

Interactive DICOM image transmission and telediagnosis over the European ATM network.

The European High-Performance Information Infrastructure in Medicine, n(o)B3014 (HIM3) project of the Trans-European Network--Integrated Broadband Communications (TEN-IBC) program, started on March 1996 and finished on February 1997, aimed to test the medical usability of the European asynchronous transfer mode (ATM) network in medical image transmission. The Department of Radiology, University of Pisa, Pisa, Italy, and St-Luc University Hospital, Brussels, Belgium, involved in the project as healthcare partners in the radiological domain, established several connection sessions finalized to test the usability of Digital Imaging and Communication (DICOM) image transmission and interactive telediagnosis tools in the daily radiological practice. The Pisa site was connected to the Italian ATM pilot (Sirius Network) through the Tuscany metropolitan area network (MAN), while St-Luc University Hospital was connected to Belgium ATM network through the Brussels MAN. By means of international connections provided by the European JAMES project, a link between the two sites was established, connecting both national ATM networks. Due to the large variety of hardware present in the medical centers, multiplatform software tools were used and tested: central test node (CTN) release 2.8 [3], VAT [6], NV-3.3 [7], and IDI (UCL homemade multiplatform teleradiology tool for interactive visualization and processing of DICOM images). During the telediagnosis session, lead by radiologists in both hospitals, each site submitted neuroradiological clinical cases to the other for remote consultation. The connection, available for a period of two weeks, at 2-Mbit/s bandwidth, allowed the transmission of MR images (256 x 256 x 12 bit) and simultaneous multimedia interactive discussion of the cases. Both off-line transmission and review of the images, using the CTN DICOM transfer routines, and on-line interactive image discussion, using the IDI telediagnosis software, were tested successfully from the technical and medical point of view.

Real-time ECG transmission via Internet for nonclinical applications.

Telemedicine is producing a great impact in the monitoring of patients located in remote nonclinical environments such as homes, elder communities, gymnasiums, schools, remote military bases, ships, and the like. A number of applications, ranging from data collection, to chronic patient surveillance, and even to the control of therapeutic procedures, are being implemented in many parts of the world. As part of this growing trend, this paper discusses the problems in electrocardiogram (ECG) real-time data acquisition, transmission, and visualization over the Internet. ECG signals are transmitted in real time from a patient in a remote nonclinical environment to the specialist in a hospital or clinic using the current capabilities and availability of the Internet. A prototype system is composed of a portable data acquisition and preprocessing module connected to the computer in the remote site via its RS-232 port, a Java-based client-server platform, and software modules to handle communication protocols between data acquisition module and the patient's personal computer, and to handle client-server communication. The purpose of the system is the provision of extended monitoring for patients under drug therapy after infarction, data collection in some particular cases, remote consultation, and low-cost ECG monitoring for the elderly.

Teledermatoscopy as a triage system for pigmented lesions: a pilot study.

BACKGROUND: Skin-cancer screening should rely on simple, low-cost and high-sensitivity diagnostic procedures. AIMS: To compare diagnosis and management options after the evaluation of clinical and dermatoscopic teleconsultations with a store-and-forward teledermatology screening system for pigmented lesions. METHODS: Kappa values between telediagnoses and the gold standard (histological examination) were assessed. Referral rates, diagnostic confidence level (DCL), sensitivity and specificity were evaluated in both approaches. Picture quality and time and cost investments were also measured. In total, 61 teleconsultations were evaluated. RESULTS: Sensitivity of the clinical and dermatoscopic teleconsultations was 1 for both, whereas specificities were 0.65 and 0.78, respectively (P < 0.05). DCL was higher for the dermatoscopic teleconsultations (4.75 vs. 4.14, P < 0.05). Agreement between the clinical and dermatoscopic teleconsultation was kappa = 0.89 (95% CI 0.81-0.97). Agreement with the gold standard was 0.91 (95% CI 0.82-1.00) for the clinical teleconsultation and 0.94 (95% CI 0.88-1.00) for teledermatoscopy (P > 0.05). Teledermatoscopy increased the economic investment of a teledermatology facility by 2.4 times. The GP spent 1.5 times longer on dermatoscopic teleconsultations. CONCLUSIONS: Teledermatoscopy has improved the DCL, specificity and referral rates of a teledermatology-based screening system for pigmented lesions. A more detailed economic analysis remains to be performed before recommending teledermatoscopy as a routine screening procedure in pigmented-lesion clinics.

A qualitative study examining tensions in interdoctor telephone consultations.

OBJECTIVE: Communication skills have gained increasing attention in medical education. Much of the existing literature and medical curricula addresses issues of doctor-patient communication. The critical importance of communication between health professionals, however, is now coming under the spotlight. The interdoctor telephone consultation is a common health care setting in which health professional communication skills are exercised. Breakdowns in this communication commonly occur and, surprisingly, this skill is not formally addressed in medical training. This study sought to clarify the communication issues that can occur during interdoctor telephone consultations in order to inform future educational initiatives in this domain. METHODS: Data were collected and triangulated among 3 sources: documentation of 129 telephone consults received; 51 hours of field observations of consultants, and semi-structured interviews of 12 callers and 12 consultants. Analysis was performed using grounded theory methodology. RESULTS: Overwhelmingly, participants described tensions with telephone consultation communication. Recurrent theme analysis revealed 5 key sources of tension: discursive features; context; fragmented clinical process; reason for call, and responsibility. Often, callers and consultants viewed similar instances in different and opposite manners, contributing to difficulties in the exchange. Further, a vicious cycle in which a participant's strategies to mitigate tension actually increased tension for the other participant was identified. CONCLUSIONS: Interdoctor telephone consultation has become an integral part of medical practice; however, tensions within this exchange can undermine its effectiveness. The results of this study provide a preliminary theory upon which an educational intervention to improve this communication skill can be based.
