Description

I'm hoping to receive clarification regarding the units for some specific lab, chart, and input events in the hospital and ICU database. Specifically, for the lab event id 50915 and chart event ids 229360, 227441 there are no conversions between different (seemingly non-equivalent) units of measurements when building the database. How are these events treated? There are also several inputs events (e.g. 225158, 228315, 225975, etc.) with multiple units, such as mg or dose, which are not referenced in the medications folder. Is it fine to assume all inputs are treated as binary events as this seems to be the case for most of the inputs? Thanks!

Review the online documentation and the medications folder, then trace how lab event 50915, chart events 229360 and 227441, and the listed input events are handled. Done means documenting the units, conversions, and whether inputs with multiple units should be treated as binary events.
