# TRANSFORMATION LOGIC (PSEUDO-CODE)
# The export will be 'Wide'. Apply this logic to create the Event Log:

FOR EACH Row IN Exported_CSV:
  EpisodeID = Row['Contact Serial Number']
  
  FUNCTION CreateEvent(ActivityName, TimestampColumn):
    IF Row[TimestampColumn] IS NOT NULL:
       OUTPUT_ROW = {

         'EventTimestamp': Row[TimestampColumn],
         'PatientMrn': Row['Patient MRN'],
         'DepartmentName': Row['Department at Discharge'],
         ... [All Attributes]
       }
       APPEND OUTPUT_ROW TO Event_Log

  # Execute for all 15 mappings defined above
  CreateEvent('Patient Registered', 'Hospital Admission Time')
  CreateEvent('Triage Completed', 'Triage End Time')
  ... [Repeat for all mapped columns]
