Integration of the cognitive knowledge of activity in a service oriented architecture in the home care context.

The complex nature of a home care (HC) situation induces an important need for cooperation between the health care professionals. But even if this need is sometimes evocated in reports on HC issues, it is more difficult to get precise knowledge on this cooperative activity, and, consequently, propositions for computerized HC organization and management systems. We did some researches on this topic area. Previous phases of work let us highlight the actual need for cooperation, and obtain precise information on the HC activity processes and data. In this paper, we focused on the integration of this cognitive knowledge on the design of a HC cooperation architecture. Different levels of requirements for the cooperative system are mentioned: coordination, communication of information, delegation of activity, integration of services and personal access to the tasks to perform. A description of the usefulness and use of the cognitive knowledge is proposed, the architecture design, modular, distributed, and able to integrate external services is presented, and the results of a validation test of the implemented prototype, performed with actual HC professionals in an evaluation laboratory are presented.

Communication of information in the homecare context.

Organizing the Homecare with new information technologies is nowadays an important challenge. Indeed, some medical evolutions as the improvement of the duration of life, the number of chronic diseases and some social evolutions, such as the quality of patient life, or economic evolutions, such as the reduction of hospitalisation costs, could benefit from homecare. In this paper, we present the problem of the communication of information in the homecare context. Some main phases have been described that compose the two homecare processes: a logistic process and a care process. The communication of information during homecare depends on the concerned phases: first, some exchanges of information from existing Information System to the Homecare Information System; then, some exchanges between the homecare system and the mobile health care actors; and then, some mails during the outcome phase. Coordination architecture is briefly described, and two different implementations for the communication of information during homecare are presented: one is using XML messages to exchange information between Information Systems; the other is using mobile tools for communicating with mobile actors.

Information and logistics for homecare.

TELECOS is a regional project whose ambition is to use new cooperation tools, in the context of homecare, in order to facilitate the coordinated cooperative work of health actors. Homecare can improve the quality of life for the patient and reduce costs but it also induces a lot of difficulties during organisation and care. We aim at knowing more about the activity of cooperation in the homecare context and proposing a cooperation platform which answers to the specific needs generated during homecare and which integrates new applications. In this paper, we present the results of our study of homecare. The activity analysis leads us to determine two specific processes: one concerns the implementation of human and material resources and design of the homecare protocol (the logistics process) and the other concerns the coordination of the healthcare actors during effective homecare (the care process). The first process is composed of five main phases during which an healthcare professional is required as coordinator. We then present the Worklow model used to represent the cooperation activity in homecare. We describe the activity: the tasks and subtasks are represented in a declarative way. We then briefly present our prototype, devoted to homecare management, implementing the different phases of the information process, developed in JAVA.

A modelization of the task allocation problem for prescribing activity in an ICU.

The improvement of coordination between Health Care Professionals belonging different specialities and who are extremely mobile, is a crucial problem in Medicine. A workflow System is one example of the new informatics tools which facilitate the transfer of information and responsibility between health care providers. Medical informatics systems in particular should be reactive enough to cope with the flexibility of real work situations: in this paper, we present the task allocation problem. We distinguish between the workflow control process and the notifying process, which concerns the sharing out of the tasks between the actors concerned. We focus on the impact of strategies of notification on the progress of coordinated work. We propose a simulator to model and study the different ways of sharing tasks between actors in an Intensive Care Unit's activity of prescription.

A simulation of dynamic tasks routing to improve cooperation in intensive care units.

Cooperation between Health Care Professionals is essential for the quality of care. Workflow systems could improve the transfer of informations and responsibilities within Health Care Actors. We have proposed a conversation-based Workflow in order to modelize the therapeutics plan in the ICU. In such a complex field, the flexibility of the workflow system is essential for the system to be usable. We have introduced some dynamicity by adding roles in the model. With the use of roles, the dynamicity of the workflow is assumed by the routing process. We need to use simulation to be able to study the impact of routing algorythms on the efficiency of the coordination.

Dynamic workflow model for complex activity in intensive care unit.

Cooperation is very important in Medical care, especially in the Intensive Care Unit (ICU) where the difficulties increase which is due to the urgency of the work. Workflow systems are considered as well adapted to modelize productive work in business process. We aim at introducing this approach in the Health Care domain. We have proposed a conversation-based Workflow in order to modelize the therapeutics plan in the ICU [1]. But in such a complex field, the flexibility of the workflow system is essential for the system to be usable. In this paper, we focus on the main points used to increase the dynamicity. We report on affecting roles, highlighting information, and controlling the system We propose some solutions and describe our prototype in the ICU.

An asynchronous co-operative model for co-ordinating medical unit activities.

CSCW is devoted to the analysis of interactions among human beings when performing their work together (Ellis et al., Commun. ACM 1 (34) (1991) 38-58). The main fields of application are work organisation, healthcare, education and training. Our main goal is to study the co-operative models allowing task co-ordination and conflict management between actors within a distributed environment, particularly in medical units. We do not aim to produce a practical system suitable for near-term deployment in the intensive care units (ICU), but rather an experimental system that performs and co-ordinates a range of intelligent planning tasks in ICU activities. The emphasis will be put especially on asynchronous co-operation. We apply the Workflow approach to ICU organisation through the analysis and the proposal of a co-operative model.

Telemedicine for AIDS patients accommodations.

People suffering from AIDS are subject to frequent hospitalisations. In some cases, they cannot go back home after hospitalisations, due to severe illness, family or sociologic problems. This is the reason why some therapeutic flats are at their disposal to make easier their medical follow-up after the hospital's discharge. In these Therapy Accommodation, they are treated by trained GP who often suffer from lack of information and lack of expertise in difficult cases. For this purpose we included these flats in the regional Telemedicine AIDS network to give these physicians free access to the computerised multimedia medical record of their patients and to provide them with synchronous co-operation facilities.

Dynamic workflow model for complex activity in intensive care unit.

Co-operation is very important in Medical care, especially in the Intensive Care Unit (ICU) where the difficulties increase which is due to the urgency of the work. Workflow systems are considered as well adapted to modelize productive work in business process. We aim at introducing this approach in the Health Care domain. We have proposed a conversation-based workflow in order to modelize the therapeutics plan in the ICU [1]. But in such a complex field, the flexibility of the workflow system is essential for the system to be usable. We have concentrated on three main points usually proposed in the workflow models, suffering from a lack of dynamicity: static links between roles and actors, global notification of information changes, lack of human control on the system. In this paper, we focus on the main points used to increase the dynamicity. We report on affecting roles, highlighting information, and controlling the system. We propose some solutions and describe our prototype in the ICU.
