Automated weight monitoring in chronic heart failure: the excluded majority.

We interviewed nurses and patients with heart failure who were participating in a research trial of home telemonitoring in which weight data were monitored automatically by a call centre. A total of 35 interviews were conducted and the transcripts were analysed thematically. The results indicated that nurses disagreed about the role of weight monitoring and the practicalities of telemonitoring in their daily practice, indicating that the process was idiosyncratic to each user. The lack of personal feedback and nursing contact discouraged patients from weight monitoring, suggesting that a feedback mechanism may have to be adapted to suit patients. There were other factors which created barriers to acceptance by patients and staff. Home telemonitoring for heart failure cannot be evaluated effectively using the standard approach commonly employed. New studies are required.

Use of digital images in the assessment and treatment of pressure ulcers in patients with spinal injuries in community settings.

We conducted a retrospective review of the digital images in the clinical records of 50 patients with pressure ulcers. Ten nurses independently assessed one image from each patient. There was a total of 414 responses from the nurses about the stage and location of the ulcers (83% response rate). The average agreement about the stage and location of the ulcers was 85%. The overall agreement declined as the stage of the ulcer increased. The average agreement regarding the wound descriptors was: necrosis 85%, granulation tissue 81%, ischaemia 83%, cellulitis /infection 69%, erythema 68%. Almost all nurses felt the need to change the current management of the wound (460 responses, or 92%). The nurses judged that most digital images were of good quality (17%) or very good quality (79%). The present study suggests that a high percentage of assessments for patients currently travelling to specialist clinics could be performed in the community using digital images and telemedicine.

The design of specialist paediatric cardiology telemedicine services to meet the needs of patients.

An observational study was conducted of two different videoconferencing services offered by the Royal Brompton and Harefield NHS Trust (RBH), a tertiary centre for cardiology in London. In the first, specialist cardiology advice was provided by telemedicine (384 kbit/s bandwidth) to four district general hospitals in England. In the second, specialist cardiology advice was provided via a low-cost videoconferencing system (128 kbit/s bandwidth) to the Mother and Child Institute in Belgrade. The hospitals chose to use the equipment for different purposes and in different ways. However, at the end of the study, they continued to use telemedicine for the normal provision of clinical services. The success of the projects can be partly attributed to the staff involved and in particular, to the telemedicine champions at the RBH. The needs of the patients were identified and then the telemedicine service was designed by local clinicians to meet those needs.

Off-site expert support for nurses undertaking ECGs in primary care.

One of the aims of the Department of Health is to respond to patient needs by considering how services can be delivered in more innovative ways, including more services being provided in primary care and increased activities being undertaken by nursing staff. These activities may have previously been undertaken by the GPs, or patients would be sent elsewhere, such as the local hospital, for tests/investigations. Some general practices are already using cardiac telemetry while others are awaiting feedback from system users before deciding whether to purchase services from independent providers. However, identifying how generalized results and predicted benefits will apply in a specific practice is not always straightforward. This article aims to assist the decision-making process by providing the results of an audit from eight general practices and two walk-in centres in which the electrocardiograms (ECGs) were already being undertaken by nurses. The results, which are shown for each centre, showed that the frequency of use varied between one and 27 per month, depending upon the practice. As a result of the 373 patients who had an ECG performed in practice, 76 had altered management decisions, 14 were saved hospital referral (11 of these from one walk-in centre), 18 were admitted to an acute hospital (10 from the same walk-in centre), and another 24 were referred to hospital for investigation.

Low-bandwidth teleconsultations for patients with complex congenital heart diseases.

We have reviewed our experience with a low-bandwidth paediatric telecardiology link (using ISDN at 128 kbit/s) between a tertiary centre in Belgrade and a tertiary centre in London. Over a two-year period, 12 videoconferences were held, during which 40 case histories of 38 patients were presented from Belgrade. The patients were aged 7 days to 20 years, and most of them had complex congenital heart defects. Changes in diagnosis and/or therapy occurred in 21 cases. Clinically relevant changes in diagnosis occurred in 2/40 cases (5%). In 12 cases, there were slight differences in opinion which resulted in minor changes in therapy for 9 of the patients. In another 9 patients, major changes in therapy occurred. There were no major problems with the quality of image and sound in any of the videoconferences. Our experience suggests that when there are experienced paediatric cardiologists at both ends of the connection, transmission via a single ISDN line is safe and accurate.

Telemedicine in pediatric and perinatal cardiology: economic evaluation of a service in English hospitals.

OBJECTIVES: Pediatric cardiology has an expanding role in fetal and pediatric screening. The aims of this study were to observe how district hospitals use a pediatric telecardiology service, and to compare the costs and outcomes of patients referred to specialists by means of this service or conventionally. METHODS: A telemedicine service was set up between a pediatric cardiac center in London and four district hospitals for referrals of second trimester women, newborn babies, and older children. Clinicians in each hospital decided on the role for their service. Clinical events were audited prospectively and costed, and patient surveys were conducted. RESULTS: The hospitals differed in their selection of patient groups for the service. In all, 117 telemedicine patients were compared with 387 patients seen in London or in outreach clinics. Patients selected for telemedicine were generally healthier. For all patients, the mean cost for the initial consultation was 411 UK pounds for tele-referrals and 277 UK pounds for conventional referrals, a nonsignificant difference. Teleconsultations for women and children were significantly more expensive because of technology costs, whereas for babies, ambulance transfers were much more costly. After 6-months follow-up, the difference between referral methods for all patients was nonsignificant (telemedicine, 3,350 UK pounds; conventional referrals, 2,172 UK pounds), and nonsignificant within the patient groups. CONCLUSIONS: Telemedicine was perceived by cardiologists, district clinicians, and families as reliable and efficient. The equivocal 6-month cost results indicate that investment in the technology is warranted to enhance pediatric and perinatal cardiology services.

An assessment of parental satisfaction with mode of delivery of specialist advice for paediatric cardiology: face-to-face versus videoconference.

Comparisons of parental satisfaction were made after specialist paediatric cardiology consultations were conducted either by conventional face-to-face delivery or telemedicine. Satisfaction statements were rated by 100 parents: 20 who experienced telemedicine; 56 with new children seen in the outreach clinics; 24 with children on review whose next appointment was at the specialist centre. There was general satisfaction with both types of consultations, but significant differences were noted. Those who had videoconferences felt that they had received an explanation about how the specialist advice would be obtained, and that they could see the pictures being discussed clearly. Those who had experienced telemedicine believed that teleconsultations could save them travelling time and money and they found the technical aspects of sound and picture quality acceptable. They were not discomforted by the technology and felt reassured by the consultation with the specialist. However, there was some ambivalence towards the statements suggesting that teleconsultations could take the place of conventional face-to-face consultations.

Magnetic resonance imaging for investigation of the knee joint: a clinical and economic evaluation.

OBJECTIVES: The aim of the study reported here was to investigate whether the use of magnetic resonance imaging (MRI) impacts on the clinical management of patients presenting with chronic knee problems, reduces costs, and improves patient outcome. METHODS: A single-center randomized controlled trial was conducted. Patients attending with knee problems in whom surgery was being considered were randomized either to investigation using an MRI scan or to investigation using arthroscopy. The study investigated benefits in terms of avoidance of surgery and patient health-related quality of life (using SF-36 and EQ-5D). Costs were assessed from the perspectives of the National Health Service and patients. All analyses were by intention to treat. RESULTS: The trial recruited 118 patients. No statistically significant differences were found between groups in terms of health outcome. However, the use of MRI was associated with a positive diagnostic/therapeutic impact: a significantly smaller proportion of patients in the MRI group underwent surgery (MRI = 0.41, No-MRI = 0.71; p value = .001). There was a similar mean overall cost for both groups. CONCLUSIONS: The use of MRI in patients with chronic knee problems, in whom surgery was being considered, did not increase costs overall, was not associated with worse outcomes, and avoided surgery in a significant proportion of patients.
