There appear to have been no studies of telemedicine in rural day care centres. We have assessed the feasibility of using telemedicine in eight rural day care centres in Pennsylvania, from the day care centres' perspective. The average number of children in these centres was 76 (range 20–150). The centres sent an average of 4.7 children home each month because of illness. Using telephone and face-to-face interviews, we assessed their perceived need for and familiarity with telemedicine, as well as their openness and preparedness for implementing telemedicine. Most day care centres reported a need for telemedicine and were open to learning how to use it. Some centres were concerned about adequate space for the equipment, but overall, the centres felt that their resources were adequate. Telemedicine in rural day care centres appears to be feasible, and would have the potential to save time and money for parents, as well as perhaps improving health care for children in rural areas.

We assessed the feasibility of using a camcorder mobile phone for teleconsulting about cardiac echocardiography. The diagnostic performance of evaluating left ventricle (LV) systolic function was measured by three emergency medicine physicians. A total of 138 short echocardiography video sequences (from 70 subjects) was selected from previous emergency room ultrasound examinations. The measurement of LV ejection fraction based on the transmitted video displayed on a mobile phone was compared with the original video displayed on the LCD monitor of the ultrasound machine. The image quality was evaluated using the double stimulation impairment scale (DSIS). All observers showed high sensitivity. There was an improvement in specificity with the observer's increasing experience of cardiac ultrasound. Although the image quality of video on the mobile phone was lower than that of the original, a receiver operating characteristic (ROC) analysis indicated that there was no significant difference in diagnostic performance. Immediate basic teleconsulting of echocardiography movies is possible using current commercially-available mobile phone systems.

We have evaluated the feasibility of using the mobile phone short message service (SMS) for symptom monitoring in patients with asthma. All consecutive patients admitted to hospital for asthma during an 11-month period were considered for enrolment (n = 497). Those meeting the inclusion criteria were randomized into a control (n = 60) and intervention group (n = 60). Patients in the intervention group received SMS messages according to a structured workflow, while patients in the control group had no SMS support. In the intervention group, the mean response rate to the messages was 82%. There was an improvement in the Asthma Control Test (ACT) scores in 36 subjects in the intervention group compared to 28 subjects in the control group. There were reductions in the number of nebulizations in 54 subjects in the control group compared to 50 subjects in the intervention group, and reductions in emergency department visits in 57 subjects in the control group compared to 51 subjects in the intervention group. However, none of these differences were significant. There was no reduction in admission rates in either group (P = 0.5). The service was accepted by most patients, but its long-term effectiveness on the management of asthma remains to be determined.

It has been reported that economic evaluations of telemedicine are less adherent to methodological standards than economic evaluations in other fields. Systematic reviews also show that most studies evaluate benefits in terms of the cost savings, with no assessment of the health benefits for patients. In a recent review of economic evaluations, I found 33 articles that measured both costs and non-resource consequences of using telemedicine in direct patient care. This represents a considerable increase compared to previous reviews. The articles analysed were highly diverse in both study context and applied methods. Most studies used multiple outcome measures, such as diagnostic accuracy, blood glucose levels, wound size or quality-adjusted life-years gained. The effectiveness measures appeared more consistent and well reported than the costings. Objectives, study design and choice of comparators were mostly well reported. However, most studies lacked information on perspective and costing method, few used general statistics and sensitivity analysis to assess validity, and even fewer used marginal analysis. These shortcomings in economic evaluation methodology are relatively common and have been found in other fields of research.

We developed a wireless personal digital assistant (PDA)-based teleradiology terminal which allowed a secure connection to the hospital's Picture Archiving and Communication System (PACS) through the DICOM protocol. Ten members of the hospital's medical staff completed a questionnaire about its mobility, usability, stability, performance and diagnostic efficiency in a real health-care environment. There was a high degree of satisfaction with the system's mobility (mean score 4.1, SD 1.0, on a five-point scale), usability (mean score 4.2, SD 1.1), stability (mean score 3.9, SD 0.4) and performance (mean score 4.2, SD 0.6). The system was evaluated as a tool for providing assistance in diagnosing thyroid nodules from ultrasound images. A total of 144 ultrasound images with thyroid nodules were assessed by an expert. Six image quality attributes were evaluated. The physician concluded that the ultrasound thyroid images on the PDA screen were of similar quality to those displayed on a diagnostic visual display unit screen. However, the expert found difficulties in diagnosing microcalcification, internal echo texture and vascularity. The PDA terminal provided rapid, secure and convenient portable access to PACS images and the image quality was sufficient for diagnostic interpretation of ultrasound images of the thyroid.

A telepsychiatry project was conducted to improve access to culturally appropriate care providers (i.e. culturally competent, bilingual clinicians) by the use of videoconferencing. A self-completed retrospective questionnaire survey was conducted with asylum seekers, refugees and migrants. The purpose of the referral was either for diagnostic assessment with a subsequent treatment recommendation, or for treatment via telepsychiatry. The service was free of charge for the patients involved. Over a period of 34 months (starting in January 2005), 61 patients participated in the pilot project. The patients' residency status was: refugees (n = 45), asylum seekers (n = 12), migrants (n = 3) and domestic (n = 1). A total of 318 telepsychiatry sessions (lasting 35–45 min) was conducted, with an average of 5.2 sessions per patient. Nine languages were spoken during the study period (Danish, Arabic, Farsi, Somali, Kurdish, Polish, Bosnian, Serbian and Croatian). A total of 52 patients completed the questionnaire. Patients reported a high level of satisfaction and willingness to use telepsychiatry again and recommend it to others. They preferred telepsychiatry via their mother tongue, rather than interpreter-assisted care.

We conducted a retrospective study of incident reports concerning the national, nurse-led telephone triage system in Sweden. The Swedish Health Care Direct organization (SHD) is staffed by registered nurses who act as telenurses and triage the callers' need for care, using a computerized decision support system. Data were collected during 2007 from all county councils that participated in the SHD and were analysed using content analysis. Incident reports were then compared concerning differences in reported categories and who reported the errors. The 426 incident reports included 452 errors. Of the analysed incident reports, 41% concerned accessibility problems, 25% incorrect assessment, 15% routines/guidelines, 13% technical problems and 6% information and communication. The most frequent outgoing incident reports (i.e. sent from SHD to other health-care providers) concerned accessibility problems and the most frequently incoming reports (i.e. sent to SHD from other health-care providers) concerned incorrect assessment. There was a significant difference (P < 0.001) between outgoing and incoming reports regarding the main category. Telenurses have limited possibilities for referring the caller to their primary health-care provider or specialist, which may cause them to over-triage or under-triage the callers' need for care. This over-triage or under-triage may in turn cause other health-care providers to report incorrect assessment to SHD. The implications for practice are that poor accessibility is a matter that should be addressed and that the reasons for incorrect assessment should be explored.

We evaluated the validity of remote pure tone audiometric testing conducted from North America on subjects in South Africa. Desktop-sharing computer software was used to control an audiometer in Pretoria from Dallas, and PC-based videoconferencing was employed for clinician and subject communication. Thirty adult subjects were assessed, and the pure tone audiometric thresholds (125–8000 Hz) obtained through conventional face-to-face and remote testing were compared. Face-to-face and remote audiometry thresholds differed by 10 dB in only 4% of cases overall. The limits of agreement between the two techniques were –8 and 7 dB with a 90% confidence interval of –5 to 5 dB. The average reaction times to stimulus presentations were similar, within –108 and 121 ms. The average test duration was 21% longer for remote testing (10.4 vs. 8.2 min). There were no clinically significant differences between the results obtained by remote intercontinental audiometric testing and conventional face-to-face audiometry. It may therefore be possible to expand the reach of audiological services into remote underserved regions of the world.

We conducted a six-month randomised controlled trial of home telemonitoring for patients with chronic obstructive pulmonary disease (COPD). A total of 40 stable patients with moderate to severe COPD who had completed pulmonary rehabilitation took part. They were randomised to receive standard care (controls) or standard care plus home telemonitoring (intervention). During the monitoring period, patients in the telemonitoring group recorded their symptoms and physical observations twice daily. The data were transmitted automatically at night via the home telephone line. Nurses could access the data through a website and receive alerting email messages if certain conditions were detected. The patients completed the St George's Respiratory Questionnaire, Hospital Anxiety and Depression and the EuroQoL EQ-5D quality of life scores before and after pulmonary rehabilitation, and then periodically during the trial. There were significant and clinically important improvements in the scores immediately following pulmonary rehabilitation, but thereafter there were no differences in quality of life scores between the groups at any time, or consistently within either group over time. The study showed that telemonitoring was safe but, despite being well used, it was not associated with changes in quality of life in patients who had stable COPD.

We studied self-observations related to weight management recorded with a Wellness Diary application on a mobile phone. The data were recorded by 27 participants in a 12-week study, which included a short weight management lecture followed by independent usage of the Wellness Diary. We studied the validity of self-observed weight, and behavioural changes and weight patterns related to weight management success. Self-observed weight data tended to underestimate pre- and poststudy measurements, but there were high correlations between the measures (r ≥ 0.80). The amount of physical activity correlated significantly with weight loss (r = 0.44) as did different measures representing healthy changes in dietary behaviours (r ≥ 0.45). Weight changes and the weekly rhythms of weight indicated a strong tendency to compensate for high-risk periods among successful weight-losers compared to unsuccessful ones. These preliminary results suggest that the mobile phone diary is a valid tool for observing weight management and related behaviours.

We investigated the perceptions of people about the safety, security and privacy of a telecare monitoring system for adults with developmental disabilities living in residential settings. The telecare system was used by remote caregivers overnight, when staff were not present in the homes. We surveyed 127 people from different stakeholder groups in the state of Indiana. The people surveyed included those with knowledge or experience of telecare, and those without. The stakeholders were clients, their advocates, service provider administrators and independent case coordinators. The responses in each category for every group were positive except one: only 4 of the 11 telecare case coordinators agreed that the telecare system provided a secure environment. Overall, the telecare system was perceived to be as safe, secure and private as the conventional alternative of having staff in the home.

We developed an interactive mobile-phone based application, SmartDiet, that analyzes daily nutrition intake and patterns of daily exercise. It provides a personalized diet profile and promotes knowledge about nutrition using a diet game. We evaluated the effectiveness of the SmartDiet application in terms of acquiring dietary information, weight control and user satisfaction. A case-control study was conducted over a six-week period, with 19 people in the intervention group and 17 people in the control group. During the study, a total of 235 successful data transmissions were performed from the mobile phones and there was a mean of 12.4 transmissions per participant. The three body composition measures (fat mass, weight and body mass index) decreased significantly after the intervention in the intervention group, but there were no significant changes in the control group. In a questionnaire survey at the end of the study, the majority of the participants responded that the system was useful for obtaining information and managing the diet process. The SmartDiet mobile weight management application appears to contribute to weight loss in obese adults.

We studied the e-health system used in Nishi-aizu Town in Fukushima Prefecture in Japan. The system allows elderly people at home to transmit vital signs data to the Town's health centre, where nurses provide advice based on the data. Our hypothesis was that the e-health system in Nishi-aizu Town reduced the need to visit clinics. We attempted to prove this by a regression analysis, in which days for treatment were compared between users and non-users of e-health. The results showed that days for treatment of e-health users were shorter than those of non-users by 1.6 days per year. Thus the total reduction in expenditure as a result of fewer hospital visits (emergency and elective) was about 16,000 yen per year. In a previous study, we proved that in Nishi-aizu Town the medical expenditure of e-health users was smaller than those of non-users by 15,688 yen. The results of the present study therefore coincide with those of the previous one and show that the reduction of medical expenditure is principally caused by the reduction of days for treatment.

Email could be used in primary health-care settings for delivering health promotion and disease prevention information, providing an alternative method of delivery for brief interventions. We examined the literature on the use of email for this purpose. Systematic review methodology was used. The main medical databases were searched and there were no restrictions by study design, health-care setting or population. The search identified ten relevant articles, only one of which was a randomised controlled trial. Many articles discussed the potential use of email for health promotion and disease prevention but did not provide evidence. There is much scope for further research in this area.

To provide a baseline for future planning we conducted a survey of the use of telemedicine in the state of Western Australia. A questionnaire was designed, validated and posted to all public and private health-care facilities in Western Australia (metropolitan hospitals, country hospitals and nursing posts). Of the 132 questionnaires sent out, 102 were returned (77% response rate). Seven of the responding hospitals (all public) were classified as mainly providers of telehealth services and 95 (both public and private) were mainly receivers. Of these 95 receivers of services, 58 facilities (61%) reported that they had access to videoconferencing for telehealth purposes. The most common purposes for which videoconferencing was used were reported to be education (76% of those using videoconferencing), wound care (55%) and psychiatry (53%). The most common store-and-forward application was tele-ECG, which was reported by more than half (54%) of respondents. Eighty-five percent of public health-care facilities reported the use of telehealth (either videoconferencing or store-and-forward) in comparison with 24% of those in the private sector. There was a tendency for facilities further away from Perth to be users of more telehealth services: the correlation between distance and the number of telehealth services received was significant (Spearman's rho = 0.54, P < 0.001). The survey showed that about 73% of responding health-care facilities in Western Australia were using telemedicine.

We established a medical education website to deliver real-time, clinical case-based education to sites in Somaliland from the UK. The website was based on a web 2.0 social networking concept in order to recreate, as nearly as possible, the clinical bedside teaching experience. A survey showed that medical students in Somaliland had sufficient computer access to exploit the website. Teaching began in December 2008 and the teaching programme has developed into a regular weekly teaching session involving up to seven different student groups in Somaliland at different locations. As well as north-south teaching, the website has been employed to support a study module in London. Small groups of UK-based medical students have been partnered with intern tutors in Somaliland. Forty UK students have taken part in this teaching, which is now in its second year. Feedback from those involved has demonstrated that a collaboration in which both north–south and south–north teaching occurs can strengthen partnerships in which both parties contribute and benefit.

TeleDerm is a web-based service designed to provide general practitioners (GPs) with rapid assessment of dermatoscopic images of pigmented lesions and moles. During a 12-month period, GPs at the Hastings and Rother primary care trust referred a total of 660 lesion images from patients exhibiting less typical symptoms of cancer, who would otherwise have been routinely referred to hospital. The images were assessed by remote expert dermatologists. Of that total, 493 images (75%) were reported as displaying no suspect dermatoscopic structures, resulting in the GP discharging the patient. In addition, seven lesions (1%) were reported as displaying suspect dermatoscopic structures, resulting in the GP urgently referring the patient to hospital with a subsequent histological confirmation of melanoma. The overall costs per patient were reduced by 50%. In an independent survey, all 11 patients rated their experience as good to excellent. The results show that tele-dermatoscopy can provide GPs with an expert second opinion to increase the quality of diagnosis in primary care, reduce the costs of dermatology provision and provide a highly rated patient experience.

Well-implemented telehealth systems can reduce the total costs of care by reducing emergency hospital visits and unnecessary treatment. Telehealth is especially well-suited to supporting patients with chronic, complex or co-morbid conditions. A substantial body of research – much from the USA – documents the value of a commercially-available system which supplements remote monitoring with daily questions about the patient's health and behaviours. However, there are still very few large scale deployments of telehealth because the best practices needed to implement it are still being developed.

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.

A telehealth system that can transmit vital signs data, and also empowers patients to maintain their autonomy and learn how to manage their disease better, can improve patients' quality of life. Such a system can form part of a high-quality and efficient health-care service. The Bosch telehealth system, which focuses on self-management, has been used by thousands of patients with long-term conditions in the USA and Europe. The efficiency of the programmes, as well as their positive effects on quality of life and compliance, have been proven for a number of chronic conditions, as well as for patients with multiple co-morbidities.
