Description

I am currently trying to pull blood flow rates for ICU intermittent hemodialysis patients. I'm doing this by first identifying the hemodialysis (itemid = 225331) start and end times in procedureevents, then looking at all chartevents in that timeframe for a particular patient. However, it looks like, for many patients, blood flow rates (itemid = 224144) are only recorded during CRRT sessions, and are missing for IHD sessions. Would the blood flow rates be recorded under a different itemid for IHD patients? Or possibly in a different table? Any suggestions would be appreciated!

Not sure it's routine practice to document flow rates during IHD. When I was digging through those itemid I didn't see anything IHD specific. It's very likely not in the charted data in MetaVision.
