How to find patients who enter ICU due to specific diseases？

[tohokulgq]

I want to find patients who have entered ICU due to pneumonia, and these patients have no history of sepsis before, How should I do?
I tried use admissiondx table to find patients with pneumonia,But I'm not sure if they were with sepsis when they were diagnosed into admissiondx table.

The APACHE admission dx system used does not have many choices for sepsis but you should be able to find it under the cardiovascular system diagnoses. This will provide the primary reason for admission for that specific stay. There isn't a consistent and reliable way to identify a past history of sepsis.

thank you so much for your reply!

So the primary reason for ICU admission is APACHE admission records which in admissiondx, right?
and now I think maybe the diagnosis history could be found in pasthistory table.

Yes but be aware that the past history table is generally not thoroughly documented so absence of a dx listed does not necessarily mean there is not a past history of it.

Sorry to bother you again.

I want to know the meaning of 'activetx' in apachepredvar table.

Because i am doing the machine learning research right now and 'activetx'is the most important variable after the analysis of the machine learning model, but there are less explanation of this character.

Your answer will help me a lot! !
