RESULT:

  • ~ 25000 images / d
  • ~ 500 studies / d
  • manual control takes 5 - 15 min / modality
  • ~ 3h/d for the complete department

conclusions
Conclusions
  • flexible implementation, less independant from a vendor
  • MWL, MPPS, StComm improve clinical workflow, data consistency, quality of documentation,...
  • IHE is a pragmatic model for the clinical scenarios
  • IHE profiles should become regular part of RFPs
  • IHE Process fit also outside Radiology (e.g. Lab., Card.)
  • IHE is NOT a standard, it is beyond !!!
  • IHE solves daily-life problems by Integration Profiles

Using IHE there will be

less work for „Consultants“

like this one....
