Which abbreviation is recognized as error-prone according to the Institute for Safe Medication Practices (ISMP)?

The abbreviation "qod," which stands for "every other day," is recognized as error-prone by the Institute for Safe Medication Practices (ISMP). This designation comes from the potential for confusion it can create, particularly when misread as "qid" (four times a day) or even as "every day." This misunderstanding can lead to significant medication errors, affecting patient safety.

The concern around "qod" emphasizes the importance of writing clear and unambiguous medication orders. Healthcare providers are encouraged to avoid abbreviations that can be misinterpreted and instead use full terminology that clearly conveys the timing of medication administration. This practice ensures that both pharmacists and other healthcare professionals can accurately interpret the instructions without ambiguity.

In contrast, the other abbreviations—"daw" (dispense as written), "qid" (four times a day), and "mcg" (microgram)—are not designated as error-prone by ISMP, as they are generally understood and less likely to be misinterpreted in typical usage. Understanding why certain abbreviations are considered problematic aids in fostering more precise communication in medication management and reinforces the necessity for caution in their application.
