A pilot study of telemedicine for new neurological outpatient referrals

We investigated whether new patients attending a neurological outpatient clinic could be safely managed by neurologists at a distance, using a video-link. In Northern Ireland, a video-link, transmitting at 384 kbit/s, was set up between a neurological centre and a small rural hospital 140 km away. Twenty-five unselected patients who had been referred by their family doctor were assessed by a neurologist using the telemedicine link and then immediately by another neurologist face to face. Examiners were blinded to the results of each other's assessment. In 24 cases the diagnoses made after the telemedicine and face-to-face examinations were identical. There were minor differences between the type and number of investigations requested, and the requirements for treatment and follow-up between the two groups. Disposal method was the same in 21 of the cases. No major organizational difficulties were encountered during the study. The study showed that neurologists can deliver outpatient neurological care to distant patients using telemedicine. This has the potential to allow access to assessment for the large number of neurological outpatients who might otherwise be denied it.     

HMO physicians' use of referrals

Clinical uncertainty is a source of variation in medical decision-making as well as a source of work-related stress. Increasing enrollment in organized health care systems has intensified interest in understanding referral utilization as well as issues such as physician dissatisfaction and burnout. We examined whether primary care physicians' affective reactions to uncertainty and their job characteristics were associated with use of referrals and burnout. Data came from mail surveys of primary care physicians practicing in two large group model health maintenance organizations (HMOs) in the USA. Consistent with past research, we found that younger physicians had higher referral rates than older physicians, and that general internists had higher rates than either family practitioners or pediatricians. Greater stress from uncertainty increased referrals and referrals were negatively correlated with heavier work demands (patient visits per hour). Greater stress from uncertainty, perceived workload (too high) and a sense of loss of control over the practice environment were associated with higher levels of burnout.     

A cohort study of acute plastic surgery trauma and burn referrals using telemedicine

A store-and-forward telemedicine system was used to supplement normal telephone referrals to the plastic surgery unit at the Queen Victoria Hospital (QVH). During a 12-week prospective study, 11 units (8 hospitals and 3 minor injury units) with the telemedicine system and 10 units (8 hospitals and 2 minor injury units) without it regularly made referrals (at least 10) to the QVH. There were 389 referrals from the telemedicine-equipped units and 607 telephone referrals from the non-telemedicine units. The telemedicine system was used for 246 of the 389 referrals (63%) made from telemedicine-equipped units. There was a significant difference in the management of patients when the telemedicine system was available, with more patients booked directly into day surgery and fewer attending for assessment. The burns unit and the day surgery unit demonstrated a significantly improved accuracy of triage. Telemedicine could have a valuable role to play in the triage and planning of acute plastic surgery referrals.     

Use of telemedicine in the management of infectious diseases

Communication technologies have invaded our daily lives. Several studies have assessed these technologies in the management of infectious diseases (mainly HIV). Weekly short text messages and real-time compliance monitoring assessed in HIV patients are both associated with higher compliance in low-income countries. Virtual consultations to monitor stable chronic HIV patients or tuberculosis treatment in high-income countries appear to be acceptable and efficient. Although assessed in small studies, virtual monitoring seems to reinforce the doctor–patient relationship and the relation between primary care settings and hospitals in various infectious diseases (endocarditis, urinary tract infection, skin and soft tissue infection, HIV, tuberculosis, hepatitis C). A better prevention of infectious diseases (mainly sexually transmitted infections) seems to be observed with telemedicine tools. As fees for teleconsultation or telemonitoring have yet to be defined, the development and evaluation (cost effectiveness) of these tools are difficult. The regulatory framework will need to be improved to encourage such developments, all the while ensuring the confidentiality of data. The development of new tools will require the collaboration of physicians, users, and healthcare systems.     

Measurements of the clinical competence of doctors and nurses to process telemedicine referrals for burns patients

Simulated telemedicine referrals were used to test the ability of groups of clinicians to manage telemedicine referrals of patients with burn injuries. Sixty-one participants recorded burn depth from digital images using a four-point scale. The definitive ('gold standard') diagnoses were based on a review by an experienced consultant burns surgeon. Sixty clinical cases that reflected the routine referrals to a specialist burns service were used for the study. The mean kappa scores for the participants ranged from 0.33 to 0.58, indicating poor to good agreement. The scores for the groups all had a similar pattern, with more experienced staff scoring higher than junior staff. The doctors and nurses specializing in burns had higher scores than the general surgical nurses.     

The use of telemedicine in primary care for women with cervical cytological abnormalities

Telemedicine can be used in two different ways in the context of the National Health Service Cervical Screening Programme. The first method allows primary health-care providers to offer direct online booking of clinic appointments according to predefined algorithms based on the woman's cytological abnormality. The second method is telecolposcopy, which is designed to be used by nurses in primary care. Preliminary data confirm that such a system can be used reliably to make diagnoses. The technology is easily adaptable for realtime teleconsultation.     

Low-bandwidth telemedicine for pre- and postoperative evaluation in mobile surgical services

Low-bandwidth telemedicine was used for the pre- and postoperative evaluation of patients treated by a mobile surgery service in remote Ecuador. Realtime and store-and-forward telemedicine was employed, using PCs connected via the ordinary telephone network. Between February 2002 and July 2003, 144 patients were studied preoperatively and 50 postoperatively. It was possible to establish 20 satisfactory preoperative realtime connections, which allowed good-quality, simultaneous audiovisual transmission. Thus, there were 124 preoperative assessments done by store-and-forward telemedicine and 50 postoperative assessments. Diagnoses and management plans made by a surgeon using telemedicine were compared with those made independently by a second surgeon, who saw the patient face to face. Due to poor quality of the transmitted images, 43 patients were excluded from the preoperative study and 13 from the postoperative study. In the 101 preoperative evaluations, there was agreement in 78 cases (77%); in the 37 postoperative evaluations, there was agreement in 36 cases (97%). Telemedicine may reduce the time required on site for preoperative planning, and may provide reliable postoperative surveillance, thus improving the efficiency of mobile surgery services.     

Preliminary evaluation of the use of a CDMA-based emergency telemedicine system

We have conducted a preliminary evaluation of the use of a code division multiple access (CDMA)-based emergency telemedicine system to be used by emergency rescuers providing first-aid treatment for patients. The prototype system included five instrumentation modules for measuring non-invasive arterial blood pressure (NIBP), arterial oxygen saturation (SpO(2)), six-channel electrocardiogram (ECG), blood glucose concentration and body temperature. The patient data were transferred to a doctor's PC through CDMA and TCP/IP networks using an embedded personal digital assistant (PDA) phone. Performance tests in the laboratory showed that the system provided reliable values with error ranges within +/-1% for heart rate, +/-5 mmHg for NIBP, +/-2% for SpO(2) and +/-1% for glucose. The feasibility of the prototype system was then evaluated with 15 real emergency patients on Jeju Island over a two-month period. Measured data were transmitted from a moving ambulance to the emergency medical centre without significant CDMA connection loss or transmission errors. The average transfer time was 8 min. Four emergency doctors and 11 rescuers completed a questionnaire. There were favourable reviews from the users.

The surgical management of faecal incontinence

The surgical management of faecal incontinence is complex and technically demanding. Surgery should only be offered once the aetiology has been correctly identified and the patient has been counselled regarding outcomes of success. This may only approach 80%, with long-term results declining with time.     

A success-story in cross-border telemedicine in Europe: The use of intra-operative teleneuromonitoring during aorta surgery

Despite its potential benefits, telemedicine across borders in Europe is still in its early stages and little has been written about these collaborations. This paper aims to explore the factors, which have supported the implementation of a cross-border teleneuromonitoring collaboration between hospitals in the Netherlands, Germany and Switzerland. Semi-structured interviews with key actors were recorded and fully transcribed, and were analysed using framework analysis. Our results indicated that an array of factors facilitated collaboration in telemonitoring and assured its success and sustainability: (1) a real need to initiate the collaboration, (2) real benefits for all the parties involved, (3) agreed protocols and procedures from the start to overcome differences in healthcare systems, (4) two driving forces to sustain the collaboration; a quest for improved quality of care and for innovation, and (5) recognition that this is a bottom–up collaboration initiated by health care professionals who trusted each other.     

Physicians' opinions and practices on the use of medical referrals at hospitals

This work aims to take stock of the actual utilisation of medical standards (references), through a study of opinions and practices of the medical managers working in the clinical services of a university hospital centre. A survey through interviews was proposed to 103 medical managers, 101 responded to the questionnaire (38 Unit directors and 63 directors of "UF" units). Medical standards are used essentially as a teaching aid by 80% of doctors. Some of them (48%) make them available to prescribing doctors in the unit, and for 36% there exists an informational procedure for new residents. Evaluation studies concerning the implementation of medical standards remain rare (7 studies). Medical standards appear to be more useful for improving quality of care (90%) then for controlling health expenditures (72%). The majority of medical managers (72%) consider that certain standards should be opposable to hospitals. The medical managers of the university hospital centre are in favour of developing standards of clinical practice.
