Out of Hospital Mortality in MIMIC-IV v3.0 #1798

Closed JZL429 closed 2 hours ago

JZL429 commented 4 hours ago

Hi,

In the newest v3.0 update you said that 'Out of hospital mortality is available for up to 1-year post hospital or ED discharge'. I was wondering where do you have this information in the database? Thank you very much for the help!

The dod column in the patients table will have the date of death. If the patient is alive at the time of data collection, the column will be null. If the patient died more than 1 year after their last discharge (either ED or hospital), then this column will be NULL. Therefore you can use it for 1-year post hospital discharge mortality.

Since patients have more than one admission, the dod column is often more than 1-year after any given admission, but it cannot be more than 1-year after their last admission. This limitation of follow up is done for deidentification purposes.
