Which is on the do not use list on the Joint Commission CBC U. MS. UI.?

The Joint Commission's "Do Not Use" list includes abbreviations and symbols that can lead to confusion and errors in medical documentation. For example, the abbreviation "U" for "units" is discouraged because it can be mistaken for the number "0" or "4," leading to medication dosing errors. The preferred term is to write "units" in full to ensure clarity and safety in patient care.
