New to OHDSI and grateful for the OHDSI resources including the forum, Thank you!
We are looking to implement an OHDSI solution for a Datalake/Datawarehouse solution we have that has its own data model. Data in this system is from multiple sources and varies in how much of the data is coded and how it is coded. Using Rx as an example, we have data where we have RXNORM codes or NDC code in some cases. But in other cases we have only a text string and/or a mapping to a Value Set or a grouping of Value Sets that we have defined. For example in some cases we may only know that a patient is taking an Ace Inhibitor or a beta blocker and we would like to capture this.
Is there a way to use OHDSI to do each of the following:
- Indicate that the patient is taking a medication that maps to an existing VSAC Value Set
- Indicate that the patient is taking a medication that maps to a collection of VSAC Value Sets
- Indicate that the patient is taking a medication that maps to a Value Set that is defined by us (i.e. can we create a Value Set internally in OHDSI and then map values to it)
A solution for this is not jumping out at me from the documentation I’m looking at here (but I am new to this and could be missing it). Is there other documentation that covers this specific topic?
