Hi everyone,
I am working on a project that explores the clinical effects of Vitamin C (ascorbic acid) in critically ill patients.
Recently, I noticed that three published papers (up to Jan 2026) reported studies using “Vitamin C exposure” based on MIMIC data. However, I have had great difficulty locating Vitamin C records in the database.
Specifically:
Does Vitamin C actually exist as a structured variable in MIMIC (III or IV)?
If yes, in which tables should it appear (pharmacy / prescriptions / inputevents / others)?
Are there confirmed itemid (or drug names / codes) that correspond to intravenous or oral Vitamin C?
I have searched for keywords in d_items, d_labitems, and medication tables, but still cannot reliably identify Vitamin C administration.
If anyone has experience with this or has successfully extracted Vitamin C data from MIMIC, I would really appreciate your guidance or examples.
look in prescriptions / emar for ascorbic / vitamin c, and labevents/d_labitems if you want serum levels. no dedicated vitamin-c table.
Thank you for your reply. It seems we got the same results from our inquiries.
“No dedicated Vitamin C table.” That is what I was worried about. I had previously seen quite a few retrospective studies using the MIMIC database to investigate the therapeutic effects of Vitamin C.....
opened #2155 — no dedicated vit-c table; look in prescriptions/emar for ascorbic/vitamin c (and labevents if you want serum levels). papers are almost always using those medication tables.

docs(mimic-iv): explain where Vitamin C appears in MIMIC
docs: link README(s) to Vitamin C notes
docs(mimic-iv): ensure documentation helper-query folder exists
docs(mimic-iv): sample prescriptions search for Vitamin C
docs(mimic-iv): sample eMAR search for Vitamin C
docs(mimic-iv): cross-link Vitamin C notes to terminology docs
