Evaluation of the practical feasibility and acceptability of home monitoring in residential homes.

Three residential homes to the north-west of London, with their associated medical centres, were equipped with telemonitors to measure several variables, including seven-lead electrocardiogram, blood pressure, oxygen saturation, heart rate, temperature and respiration. The monitors could be operated by non-medical personnel. After recording, the data were transmitted via the Internet to a server. A total of 24 patients with a variety of chronic conditions were monitored regularly for a period of one year. Data transmission was found to be unreliable on occasions and was improved by extending the wireless network in the homes. Data access and presentation were considered acceptable, although suggestions for minor changes were made. No discernible impact on disease management, diagnosis or care was observed as a result of the monitoring. However, interviewees saw several potential benefits and patient acceptance was very good. The monitoring was found to be generally acceptable and feasibility was considered to have been largely proven.

A new monitoring service for long term residential care.

eVital, a European funded project, aims to investigate the issues in the provision of vital signs monitoring services in the community. For the UK pilot, services to monitor the vital signs of patients in residential care homes by remote health care workers have been established. In particular, the aim was to allow the resident's own GP to observe the ECG, blood pressure, SpO2, temperature and respiration whilst still in the health centre and be able to advise on the most appropriate action should a crisis occur. As outcomes, this pilot project was designed to determine feasibility, channels of communication between key players and assess the technology. Trials have been under way for four months and preliminary results are promising. Residential home staff have commented on the extra level security they feel in being able to "summon" medical support for residents for whom they may have concern. Patient's relatives have also commented on the reassurance they experience from knowing that the resident is being monitored.

A reference architecture for telemonitoring.

The Telecare Interactive Continuous Monitoring System exploits GPRS to provide an ambulatory device that monitors selected vital signs on a continuous basis. Alarms are sent when parameters fall outside preset limits, and accompanying physiological data may also be transmitted. The always-connected property of GPRS allows continuous interactive control of the device and its sensors, permitting changes to monitoring parameters or even enabling continuous monitoring of a sensor in emergency. A new personal area network (PAN) has been developed to support short-range wireless connection to sensors worn on the body including ECG and finger worn SpO2. Most notable is use of ultra low radio frequency to reduce power to minimum. The system has been designed to use a hierarchical architecture for sensors and "derived" signals, such as HR from ECG, so that each can be independently controlled and managed. Sensors are treated as objects, and functions are defined to control aspects of behaviour. These are refined in order to define a generic set of abstract functions to handle the majority of functions, leaving a minimum of sensor specific commands. The intention is to define a reference architecture in order to research the functionality and system architecture of a telemonitoring system. The Telecare project is funded through a grant from the European Commission (IST programme).

A Technology-assisted approach to integrating healthcare in the community.

The fragmentary nature of healthcare provision in the United Kingdom presents particular problems for many patients with vascular disease. The management and organization of this disease are also costly for the National Health Service (NHS). Hence, so any attempt to keep hospital visits to the minimum while at the same time aiding effective treatment is to be welcomed. Information in the current NHS is stored in various places and access to it is restricted. There is no central, complete, patient record that is accessible to all healthcare professionals at the various levels of care. There is also no mechanism that allows the patient to interact with his or her local nurse and/or doctor/general practitioner (at primary-care level) involving the specialist/consultant (at secondary-care level). The concept and conduct of an ulcer care program for such patients are described in this paper. Nurse-led, this novel approach uses an innovative information technology system to bring together the isolated 'islands' of knowledge and information held by both the patient and healthcare professionals involved in their care. The technology described here combines both store and forward and real-time video. Informal feedback from patients, community nurses, doctors/general practitioners, and specialists/consultants suggests that such an approach is well received. However, we conclude with a discussion of the complexities involved in the interaction between technology and people and the implications for the management of healthcare.

The effect of telemedicine on consultation time.

We have implemented an 'evidence-based referral' for primary care patients in dermatology, cardiology and peripheral vascular disease. Telemedicine clinics bring together a district nurse, patient and vascular surgeon to discuss diagnosis, management and care. During a 30-month study, a total of 30 patients participated in telemedicine clinics. The mean consultation time fell from 23 to 10 min. In parallel, the type of consultation changed from dermatology to vascular surgery. Nineteen patients participated in vascular telemedicine clinics over the last 16 months of the study. The average consultation time was 10 min (SD 1), which included discussion of the case and negotiation of its management. The average consultation time in the equivalent outpatient clinic in the same hospital for the same consultant was 15 min. The acquisition of the relevant information in primary care could lead to a reduction of 75% in outpatient clinic appointments.

Clinical ICT systems: augmenting case management.

In order to improve the diagnosis and subsequent care given to patients, health-care workers involved in the management of their care, as well as the treatment itself, are increasingly looking at the role that information and communication technologies (ICTs) can play in supporting the complex interactions between patient, doctor or nurse, consultant and medical equipment. Effective communication both amongst health-care workers and between health-care workers and their patients in both primary and secondary care is vital; ICTs can play an important role in this. In this paper possible interpretations given to the term "telemedicine" are discussed, and then attention is turned to the challenges involved in human interaction and the role of ICTs. An example of a clinical ICT system (AIDMAN) is used to illustrate how face-to-face interaction has usefully been supported by way of a "virtual" consultation, which facilitates remote medical diagnosis and can provide improved case management.

An integrated nursing and telemedicine approach to vascular care.

We have developed a telemedicine approach to vascular care for patients being managed in primary care. District nurses visit patients in their homes. Clinical information and digital photographs can be sent by email to the vascular surgeon for assessment. Where appropriate a preliminary teleconsultation between the patient and a vascular surgeon, with the nurse in attendance, is held at the primary care centre and the management of the patient is agreed. This may include referral to surgery. Over eight months six patients with diabetes and peripheral ulcers participated in the vascular telemedicine clinic. The average consultation time was 12 min (SD 4), which included discussion of the case and negotiation of its management. Important outcomes of the new system were the ability to schedule patients for rapid referral and to have completed the management of the case during the teleconsultation.
