Identify patients who do not want to be intubated at admission

[yugangjia]

HI,
There is a query to get code status for MIMIC-III
https://github.com/MIT-LCP/aline-mimic-iii/blob/master/extras/code-status.sql
It seems that the code only look at chart events without considering poe and poe-details table.
Did anyone implement similar things on MIMIC-IV?
Is poe and poe_details sufficient for deriving that info for MIMIC-IV?
