Which of the following abbreviations is on the current Joint Commission "Do Not Use" list?

The abbreviation "IU," which stands for "International Unit," is on the current Joint Commission "Do Not Use" list. The reason for this is that the abbreviation can be easily mistaken for "IV" (intravenous) or "10" (the number ten) in practice, leading to potential medication errors. To enhance patient safety and minimize the risk of misinterpretation, healthcare professionals are advised to use the full term "International Unit" instead of the abbreviation.

On the other hand, the abbreviations mm (millimeter), UTI (urinary tract infection), and mL (milliliter) are considered safe as they are typically well understood in clinical contexts and do not have commonly recognized confusing factors that could lead to miscommunication or errors in patient care. Hence, the Joint Commission has chosen to include "IU" on the "Do Not Use" list while the other abbreviations are acceptable to use.
