AND

  • Healthcare processes are highly variable
  • > Not known what happens in a healthcare process
  • Process improvement projects
  • Time consuming to collect data

Data?

  • Each department has their system
  • Integration often difficult
  • Payment system contains all events
  • DBC: Diagnosis Treatment Combination
  • Episode of care
  • All the care steps (inpatient, outpatient, day, and after

care) that may be delivered for a specific medical problem or condition.

  • Each service delivered to a patient is linked to one DBC

Results so far

  • Complex hospital logs can be mined
  • Log pre-processing can be used to derive

understandable models

  • Filtering – for getting the right abstraction
  • Clustering – for analysing common behaviour
