Known Limitations

The cases data is generally considered as being widely valid. Nevertheless there are some limitations to be stated.

Time of stay

In most cases at a readmission in same hospital stay a new case is created. In rare cases the preceding case is reopened causing that TimeOfStay includes the time patient was on normal ward. If this issue is important you may use the tranfer log or the lacking monitor signals to remove/repair these cases. This issue is on ToDo list for future releases
