Care models for chronic condition treatment place point-of-care in the community and at patient's home and imply an organized care system ("continuous care network"). The contribution of this work consists in the proposal of a service framework to support information acquisition, integration and sharing in continuous care networks. The framework is based on a service-oriented message-oriented middleware ("SAI middleware") easing the development of context-aware and information integration applications. We describe an ongoing case study aiming at demonstrating the use of the service framework in a reference application scenario for patient conditions monitoring, alarm detection and policy-based handling.
