I'm trying to build a workflow model for subjects in the MIMIC-III data set.  there's clearly no shortage of activities in here but if I were trying to track the major steps in the process (treatment protocol?) it might start with a patient (subject_id) admission (hadm_id) showing up at a site (admission_location) and subsequently leaving (discharge_location).  But given the number of items in Chartevents, Datetimeevents, Procedureevents etal quite a bit takes place at the detail level but it's not clear if there's a summary level available or one that I can create.

So if I was trying to show the patient arriving, getting some treatment (perhaps a treatment in some major category e.g. the service description in Services or diagnosis), getting admitted, getting more treatment (same or new diagnosis), getting admitted to the ICU, getting more treatment (same or new diagnosis), getting better and getting discharged.

Is there a strategy that that might be helpful to map out the basic flow through a stay at 10K'?
