Why is a Process Model needed?Why is a Process Model needed?
Core for all healthcare activitiesFor Clinical specific tasks to be identified as distinct from othersCare and diseases span across boundaries
Synergism & Coordination between different agencies
Software DevelopmentAll mentioned abovePatient-oriented systemsIntegration of Disparate Areas of development in Medical Informatics

Are there Any Models?Are there Any Models?
None for the clinical contextMost deal with Organizational aspects of healthcare and not for clinical process
Examples:• Newman and Sorenson, 1985• Wolford, Brown and McCool 1993
Even these are not effective in many ways because they skirt the clinical issue

What Should be Model’s Scope?What Should be Model’s Scope?
Only the Interaction of the Clinician with the beneficiaryShould provide the smallest block
For building large things by assemblingAllowing anchors for other processes to be hitched to it
This also gives the definition

The inference mechanism based on the external information changes the abstractionThe inference mechanism then decides what action to implement and also takes into consideration the abstraction changes brought about most recently
