Newbie here, and I’m trying to transform a dataset into OMOP V6. I’m currently working on procedure_occurence dataset. 14% of my current dataset have NULLs for procedure_datetime field as I’ve some varied sources(EHR, Claim etc.,) that are collaborating data into the dataset. I do not want my end users to loose 14% of the data - incase they have some use cases that don’t take into account proc_date that can still use the 14% for the procedure/modifier info within the record etc.,
So, my intention is to set procedure_datetime values to some unrealistic date_time 01/01/1900 00:00:00. And end users would be made aware of the assumption.
Before I proceed further I wanted to check here to see others perspective in handling this differently and or anything that I’m missing to see ?
