Which abbreviation is included on the Institute for Safe Medical Practices (ISMP) List of Error-Prone Abbreviations?

The abbreviation included on the Institute for Safe Medical Practices (ISMP) List of Error-Prone Abbreviations is QOD, which stands for "every other day." This abbreviation is considered error-prone because it can easily be misinterpreted. For example, the confusion may arise with the abbreviation "QID" (four times a day), especially if the handwriting is unclear or the letter "O" is mistaken for a "D." Such misunderstandings can lead to significant medication errors, which is why the ISMP recommends avoiding certain abbreviations to enhance patient safety.

In contrast, while QD (once daily), PRN (as needed), and BID (twice daily) may not always be free from potential confusion, they are not currently highlighted by the ISMP as error-prone in the same capacity as QOD. Emphasizing clear communication in medication dosing is crucial in the pharmacy setting to prevent adverse events and ensure patient safety.
