According to the Mimic III documentation:
All dates in the database have been shifted to protect patient confidentiality. Dates will be internally consistent for the same patient, but randomly distributed in the future. Dates of birth which occur in the present time are not true dates of birth. Furthermore, dates of birth which occur before the year 1900 occur if the patient is older than 89. In these cases, the patient’s age at their first admission has been fixed to 300.
My question is whether the month/day/time information has been obfuscated as well... ie if the subject's ADMITTIME
is stored as 4/11/2172 19:40
- can I reliably say that the actual patient was admitted on April 11th in "some year" or has all of that information been shifted as well?
