A paradigm shift is rapidly taking place within the healthcare sector. Its focus is now shifting from in-patients to ambulatory and primary care, and to other forms of care outside hospitals. These changes demand ways of describing and analysing the contents, costs and quality care from a patient's perspective, covering whole episodes of care. The aim of CHAINE is to select and evaluate elements needed for episode building, and to disseminate and discuss the acceptability and validity of the episode concept. This discussion will encompass different persepctives: those of patients, clinicians, and public health managers. Specific attention will be given to training and education, a case study in the critical care domain, and to networking, with a special focus on the new Member States. It will point at problems and possibilities to be dealt with in a future project, aiming at producing applications supporting episode building. The CHAINE proposal will be based on the work done by CAMIREMA and TANIT.
