The development of telecare services across the UK has been supported by grants from the respective governments of Scotland and Wales, and by the DH in England. New services are being established to sometimes operate alongside existing community equipment services and community alarm services. Elsewhere they are embracing a wider range of services including rehabilitation, intermediate care and health services designed to reduce the use of unscheduled care services. This paper discusses the difficulties in understanding the scope of telecare services, and the definitions of services that will need to be confirmed so that service users can choose appropriately if offered direct payments. Two different service models are offered, one of which uses telehealth as an umbrella term to cover all telecare, e-care and m-care, and telemedicine where the former includes all such services offered in the service user’s home, including those of a medical nature. The second model views telecare alongside assistive technologies and telemedicine as one of three different technology groups designed to make people more independent or to bring care closer to home. There is significant overlap between the three groups, which justifies the introduction of a new term – ARTS (assistive and remote technology services) – to describe this area of support.
There is renewed interest in the role that may be played by community services that are based on technologies that support independence i.e. assistive technologies. Traditional forms of assistive technology include low-tech portable devices such as walking sticks, spectacles and tap turners, to more expensive fixed systems such as stair-lifts, ramps and level-access showers (that are essentially adaptations to the home). Several new items of assistive technology have appeared during the past 20 years, many depending on electronic, computing and telecommunication innovations. Systems such as environmental controllers have enabled profoundly disabled people to operate electrical appliances, motorised door and window openers and other electrical equipment through a personal interface arrangement. [In the UK] the term ‘telecare’ was selected to cover all electronic technologies of a preventive or supportive nature because it had the necessary ‘buzz’ and because it implied a modular approach and a need for a developing telecommunications infrastructure. Although the fundamental purpose of the technology is to avoid unscheduled care incidents and, in particular, the management of long term conditions, it can support independence because it is capable of overcoming the need for people to move prematurely into a nursing home environment. Such technology would appear to be a medical application of telecare, which would be consistent with the new definition of telecare described above. However, remote and regular (but not continuous) vital signs monitoring may be fundamentally different to existing UK telecare systems because the purpose is to collect data rather than offer an automated alarm. In the USA (where there is currently little use made of the UK model of telecare), remote vital signs monitoring systems are known as telehealth systems. The term “telehealth” has therefore been imported into the UK with little thought of how it co-exists alongside the telecare agenda. More perversely, telehealth has in Europe for many years been the umbrella term used for a broad range of technologies which includes telemedicine (the sharing of medical data, including scans and visual images), e-care or m-care (which involves data transfer on a mobile basis) and telecare. The result is that, under the previous model, telecare is a sub-set of telehealth technologies, whilst in the new model, apparently supported by equipment vendors and other bodies, telehealth is a sub-set of telecare.
Model 1 – Telehealth Umbrella Model
The original definition of telehealthcare effectively based its sub-sections on the location of the care that was being delivered remotely i.e. the home, some community location, and a medical facility. Telecommunication technologies have matured quickly in the 21st Century. Similarly, information systems and the embedded intelligence in devices have become progressively more sophisticated enabling them to be included in relatively low-cost equipment for the home. This yields a host of new services as shown in Figure 1. Alongside the three components of Telehealth are shown a growing range of Assistive Technologies which, though not requiring any connection to a remote care manager, nevertheless perform a valuable role in helping to overcome unmet needs.

Model 2 – Telecare Umbrella Model
Telecare has become a term used for all preventive technologies that involve the use of electronics, telecommunications and information systems. It can therefore cover the spectrum of applications from alarms through to monitoring of vital signs and activities both in the home and on the move. Thus, if terms such as telehealth were to include all forms of medical monitoring and information, including health coaching, then a broader form of telecare could extend across from environmental through to medical applications. It follows that some electronic aids to daily living, such as prompts, reminders and local alarms, might also be considered to be examples of telecare (as well as being assistive technologies). In the same way, mobile applications of worn or embedded medical devices (such as cardiac arrhythmia monitors) could be considered to be telecare when used in the home but telemedicine if data or alerts are directed to a consultant in a hospital. Figure 2 offers an alternative map of services where telecare becomes the umbrella term with assistive technologies and telemedicine covering a much smaller group of modalities that are associated with housing adaptations and hospital services respectively.

Discussion and Conclusions
Perhaps telehealth is a more important concept because everyone needs their health but not everyone will need care. If we used the term “telehealthcare” then perhaps we can avoid confusion because it clearly incorporates both telehealth and telecare. It doesn’t necessarily include traditional forms of Assistive Technologies. Amid the debate, there remains the thought that individual provision of services is required based on a holistic assessment. This is the only way of assuring that the solution is person-centred. As we are discussing equipment and services based on technology, maybe the term PROCESS Technologies (PeRsOn-Centred Equipment & Support Services) could be employed as the umbrella term. Alternatively, the coming together of assistive technologies and ICT (Information and Communication Technologies) might yield a hybrid term such as ARTS (Assistive & Remote Technology Services) which may be acceptable to all. In each case, it may be appropriate to separate the individual elements into their respective roles:
- Functional support – replacing or improving an individual’s ability to perform one or more activities of daily living with devices (including robots) which can compensate for the user’s physical, sensory or intellectual/cognitive deficiencies
- Alerts and alarms – sensors or combinations of sensors which detect situations where the individual’s safety and security (and increasingly health and well-being also) may be at risk
- Monitoring – methods of providing an on-going assessment (or analysis) of an individual’s medical, psychological, well-being, performance or behavioural state so that interventions can be offered before an emergency arises, and
- Interactive and virtual services – systems which overcome the problems of distance and isolation in advising, empowering and, hence, enabling people to become partners in the process of improving their quality of life.
Service providers of the future may need to offer all these services in order to meet the aims of commissioners. Those which reject individual service elements must be clear in advertising what they can and can’t do in order that everyone understands their limitations and/or specialities. Whilst a vision of the future potential for these technologies may be a prerequisite for service development, the adoption of standard definitions will greatly simplify the process of establishing best practice and improving service delivery and integration.

Does the article tease out all the problems? Although there is a reference to ‘proactive calling’ in one of the diagrams it does, to me, seem to omit one sense of ‘telecare’ which is widely used, particularly since the profile that Ontario Telecare has obtained. In this sense telecare is used to mean giving phone-based and online health advice to the public, as in the manner of the UK’s NHS Direct service. To what extent this type of service should be included in the taxonomy and, if so, how it should be called, should form part of our debate.
Further comment from Kevin Doughty
Just for clarification on the phone helpline angle, my view is that Telecare includes all services that rely on technology to help support a person in the own homes from a distance. A telephone helpline which offers advice on medical conditions (e.g. NHS Direct) can therefore be considered to be telecare as much as a complex video surveillance system that detects problems and initiates interventions through ‘smart home’ technology, domestic robots or an emergency response team.
