description
"An important application of both data abstraction and plan execution is the execution of clinical guidelines and protocols (CGPs) both to validate them against a large set of test cases and to provide decision support at the point of care. CGPs can be represented and executed as a hierarchy of skeletal plans. To bridge the gap between low-level data and high-level concepts in the CGP, intelligent temporal data abstraction must be integrated with plan execution. This project provides a solution to this challenge... [CGPs] are translated to a high-level plan representation language which is compiled into a network of abstraction modules by the system. This network [executes] the contents of the plans triggered by ... patient data. By this, we seamlessly integrate the synchronisation of guideline execution with observed patient state, complex temporal abstractions and execution of complex plans without requiring the user to handle the low-level details."

"The execution of clinical guidelines and protocols ... is a challenging task in high-frequency domains such as Intensive Care Units. On the one hand, sophisticated temporal data abstraction is required to match the low-level information from monitoring devices and electronic patient records with the high-level concepts in the CGP. On the other hand, the frequency of the data delivered by monitoring devices mandates a highly efficient implementation of the reasoning engine which handles both data abstraction and execution of the guideline.
...Asbru represent[s] CGPs as a hierarchy of skeletal plans and integrates intelligent temporal data abstraction with plan execution to bridge the gap between measurements and concepts in CGPs.
In this paper, we present our Asbru interpreter, which complies abstraction rules and plans into a network of abstraction modules by the system. This network performs the content of the plans triggered by the arriving patient data. Our approach [has been] evaluated to be efficient enough to handle high-frequency data while coping with complex guidelines and temporal data abstraction."
