Older people often have a complex mixture of health and social care needs and several different health and social care professionals are involved in their care. National policy in England is to promote the single assessment process (SAP), an integrated assessment of health and social care needs of older people. However, most of the current information systems do not adequately provide the functionality that is required by health and social care professionals. In this paper we discuss the suitability of agent technology, explaining why we selected it as offering the greatest potential for efficient and flexible information collection and sharing, and for supporting effective care planning. Also, we point out benefits derived from the use of agent technology in the development of health and social care systems, such as the minimization of health and social care professionals' workload. In addition, we describe how we have developed a model for an integrated information system, based on agent technology, for health and social care needs assessment of older people. Finally, we discuss issues, such as security and mobility, involved in the development of such a system, which will need to be designed and tested prior to its implementation in health and social care practice.

Health care information systems are becoming more and more computerized. A huge amount of health related information needs to be stored and analysed, and with the aid of computer systems this can be done faster and more efficiently. The Agent Oriented paradigm provides an alternative way of developing medical based systems. This article presents an initial exploration of the analysis and design of a multi-agent system to deliver the Single Assessment Process, an integrated health and social care information system for older people. The article concludes by making the following observations: Agent technology has the potential to support the development of medical and health and social care systems for older people. Nevertheless there are not many real-life agent based applications successfully applied in the health care sector. One of the main reasons is the limitation of the existing analysis and design methodologies. Thus, in order for the agent-technology to be widely accepted in the development of computer based medical information systems for older people (and in extent any medical system) it is necessary to develop a complete and mature analysis and design methodology to support the development of agent based medical systems.
