Agenda Items

1. review ACPP ontology, Rules and Stroke Management Test case

Discussion minutes

1. ACPP ontology, need to add "priority" description of a task
   • when a patient has multiple clinical problems, tasks for treating each problem are recommended. Yet each task will not carry the same urgency thus requires simultaneous actions.
   • whether the priority should be associated with each task or treatment plan of a clinical problem is to be discussed.
2. ACPP ontology patient state, we need to identify administrative state as well. Different types of patient state of a patient could include:
   • clinical state (having clinical problem)
   • physical state (walk without assistance for 5 meter)
   • operational state (on-going treatment)
   • administrative state (in-patient, home care)
3. Generic process ontology using pi calculus
   • pathways are sequences of processes. In addition to model the medical knowledge (e.g cause-result relationship between clinical problems and treatment or medication), we also need a process model for representing operational knowledge.
   • in ACPP ontology, each order (executional task) is viewed as a filfullment of a recommendation, as well as a process. We experienmented with Robin Milner's process calculus - Pi-calculus in ACPP ontology. pi-calculus theory is credited as an important fundation for mobile computing. See Robin's orginal paper1 and paper2 on pi-calculus.
4. Use of DSS
   • [Chimezie] should it be passive, in the background of physician's daily workflow, or replace current workflow to orchestrate clinical information system
   • [Davide] DSS should always run at the background, the recommendations should be suggestive, not imposing or break their workflow constantly. DDS should not tell physicians "don't do XXX". Always allow the rejection of DDS recommendation.
5. proof generation and rules
   • It is not enough to capture all medical knowledge in ontology. The use of rules is evitable. The ability to generate proof is also important for DSS.
   • For those who haven't used rules in semantic web before, Chimezie will present a tutorial section in next Tcon.
6. expected outcome of this task force
   • The ACPP ontology can be used to model different use cases from different clinical domains and therefore covering different clinical decision making styles. The stroke management use case would address the typical primary care/internal medicine approach to diagnosis and treatment, while other use cases in the surgical domain will demonstrate the ability to mimic surgeons' decision making approach

Next Tcon

July 25, 2006 Chimezie presents "how to use rules in semantic web"
