Description

Hi! I am wondering if the SAPS-II scores for ICU visits are calculated in the MIMIC-IV dataset, and which module/table are they included in? If they are not currently included, will future versions of MIMIC-IV include mortality probability scores (e.g., SAPS, APACHE, SOFA) for ICU visits? Thank you so much for the help!

Hi, You can access saps II scores in mimiciv_derived dataset, that contains sapsii table with saps ii scores.

Thanks for the response! I am wondering where I can find information on the mimiciv_derived dataset? I navigated through the module documentations for MIMIC-IV but haven't found this dataset. Thanks!

You can access mimiciv-derived dataset using Bigquery in physionet-data project. Sapsii table fields names are self-explanatory. Otherwise, if you want to have a look at how the table is built, you should download the files that enable you to build locally the database. You'll find there a directory named mimic-code/mimic-iv/concepts/score containing sapsii.sql, the script that builds the sapsii table.

Yeah, the tables in the mimiciv_derived schema don't have any online documentation, but you can read through the source code in the concepts folder, and the idea behind it is described in The MIMIC Code Repository paper. Probably we should add a MIMIC-IV derived section in the online docs, but not sure when we'll get time for that!
