The cases table is the base table of the SICdb dataset, CaseID is the identifier that relationally connects all data. For each admission to our intensive care unit one CaseID is generated. To identify readmissions, a PatientID is provided. The time between the first admission and the current is stored in field OffsetAfterFirstAdmission.

TimeOfStay is the time in seconds from Metavision admission to Metavision discharge. This time may begin with the preceding surgery, and ends when the case is closed.

There are 3 fields indicating survival. DischargeState indicates the state of the patient on ICU discharge, this data is taken from the Metavision discharge form. HospitalDischargeType gives information about how this case was closed in the clinical information system. OffsetOfDeath is the time in seconds from admission to death. This field also takes further stays into consideration and is, opposite to DischargeState and HospitalDischargeType, not linked to the stay identifier. Take into consideration that OffsetOfDeath cannot be used as long-term survival information, because it will only be set if the patient died within a stay in hospital.
