Maternity ward data

Hello everyone,
We are students who want to perform an ETL to OMOP CDM on data from the maternity ward.
The information is divided into many tables and does not always contain the information needed for CDM.
Example of existing tables:
Admission to the maternity ward (reason for application / determination of gestational age)
Birth Summary (Birth Details / Newborn Details)

We would be very happy if someone could give us guidance on how we can perform the mapping of the data when the data necessary for the CDM is not always available.
Thank you

Why don’t you make a list of all the concepts you need to figure out, and then the community will help you.

Hi @Almog_Sarafian,
Based on my experience you should start with one source table and use the table definition (OMOP CDM v5.4) to map the data, then convert the source code to a standard concept and verify that external researcher can use the atlas tool to build a cohort.
Once you have achieved this on one source you are on the right track.
