Dear OHDSI community.
I’m implementing OMOP CDM v6 for a network of ICU registries in South Asia.
We previously collected reason for ICU admission using APACHE IV diagnosis codes (we are moving towards using SNOMED).
APACHE IV diagnoses are divided into ‘operative’, eg appendectomy, and ‘non-operative’, eg anaphylaxis. These are recorded at the time of ICU admission and actually represent the reason for admission to the ICU.
I have 2 questions:
- Operative diagnoses (appendectomy, hip replacement) appear to fall into the procedure domain instead of the condition one. Is it acceptable to put these ‘operative diagnoses’ into the procedure table, instead of the condition one?
- We don’t know the time these diagnoses and procedures were made or carried out. The nearest time we have is the time of ICU admission. Is it ok to save these reasons for admission in the condition and procedure table with ICU admission time as the time of diagnosis and procedure? If not, how do I indicate that these diagnoses are actually ‘reasons for admission’?
