Duplicates in Treatment table
Hi Alistair.
I am working on patients with intra-aortic balloon pump counterpulsation (IABP), which could be found in the treatment table.
But I am confused about the multiple same records under one unitstay. For example, patients with a unitstayid of 12012486 had 5 records of IABP and only the last one was active upon discharge. (as shown in the picture)
I wonder how to understand the 5 records. Does the first record mean the start of the IABP and the second one mean another IABP or just the continuity of the first one? And does the last active record mean he died or transferred to another unit with IABP?
Looking forward to your help. Thank you. @alistairewj
It's a drop down list of active treatments - so you can imagine the nurse was continually recording the presence of the intra-aortic balloon pump until the final record, when the patient was discharged from the ICU. At that point activeupondischarge is True, and there is no more documentation as they are out of the unit.

Thank you, Alistair. I got it!
One more question, I also found that some patients who received IABP had all records "FALSE".
Does that mean there was no record of when the patient was discharged from the ICU or they had IABP removal?
Actually, some patients had the treatment "IABP removal".
Thank you!
I don't know the data generation process well enough to 100% confirm, but I would imagine that means the IABP was removed in both cases.
That is the "active upon discharge" flag so the way to interpret "False" is that the patient had the IABP removed prior to discharge from their ICU stay.

Thank you for your help!
If we understand this question the way you proposed, patients who had one "TRUE" IABP record should have all records "TRUE".
