Description

Greetings! I'm trying to extract pregnant patients diagnosed with particular disease and I have already tried using itemid=225082 (chartevents) to identify those potential pregnant individuals. However, I got puzzled about the corresponding value. According to previous issue proposed by others (https://github.com/MIT-LCP/mimic-code/issues/612), could I equal value = 0 to "no pregnancy" and value = 1 to "indeed pregnancy"?

I also noted that chartevents reside in ICU module. Thus, is it possible that some pregnant patients were only documented in hosp but could not be identified by chartevents? In this reason, I'm wondering if there exists other methods to identify pregnancy? I noted your practical response in https://github.com/MIT-LCP/mimic-code/issues/1724 but the resulted sample size was still rather limited.

Thanks for your time and support.

Start by reviewing the MIMIC-IV documentation and the linked issues 612 and 1724, focusing on chartevents itemid 225082 and the hosp data. No repository file or test is identified; done would require a documented, evidence-based method for identifying pregnancy patients and clarifying how the recorded values should be interpreted.
