Since the ICU is an extremely data-intensive environment,automated data processing is needed in the ICU. The Intensive Care Service Platform facilitates the abstraction of relevant information and supports the physicians through medical support services. These medical support services can be reused as building blocks to create new more advanced services as WS-BPEL compositions. WS-BPEL compositions are however static and need off-line creation. Therefore, in this paper, we present the extension of the Intensive Care Service Platform (ICSP) with support for automatic composition of medical support services. The on-line created new medical support services are automatically deployed within ICSP so that physicians can immediately use these medical support services. As a result, the automatic composition of medical support services is a major improvement since now physicians can create new medical support services on the fly without the intervention of programmers, resulting in greater development efficiency and an increasing number of implemented medical support services.
