DATETIMEEVENTS contains all date measurements about a patient in the ICU. For example, the date of last dialysis would be in the DATETIMEEVENTS table, but the systolic blood pressure would not be in this table. As all dates in MIMIC-III are anonymized to protect patient confidentiality, all dates in this table have been shifted. Note that the chronology for an individual patient has been unaffected however, and quantities such as the difference between two dates remain true to reality.
Identifiers which specify the patient:
SUBJECT_ID is unique to a patient,
HADM_ID is unique to a patient hospital stay and
ICUSTAY_ID is unique to a patient ICU stay.
CHARTTIME records the time at which an observation was charted, and is usually the closest proxy to the time the data was actually measured.
STORETIME records the time at which an observation was manually input or manually validated by a member of the clinical staff.
CGID is the identifier for the caregiver who validated the given measurement.
