Avoiding Potential Medication Errors Associated with Non-intuitive Medication Abbreviations.

Area of Science:

• Pharmacology
• Patient Safety
• Health Informatics

Background:

• Pharmaceutical companies utilize numerous abbreviations to designate short- and long-acting medications.
• Medication administration errors linked to these abbreviations are frequently documented.

Purpose of the Study:

• To assess the comprehension of abbreviations for short- and long-acting medications.
• To determine if modified medication labels can decrease errors in medication selection and administration.

Main Methods:

• Phase 1 involved nursing staff defining and categorizing four abbreviations by release rate.
• Phase 2 used a simulation with a medication administration record and blister pack to evaluate error reduction with varied labeling.

Main Results:

• Only 28% of nursing staff correctly defined all four abbreviations.
• 39% accurately classified all abbreviations by release rate.
• Labeling modifications in a simulation reduced potential medication administration errors.

Conclusions:

• A significant portion of study participants did not correctly understand abbreviations for medication release rates.
• Misinterpretation of abbreviations, such as 'ER' for 'emergency release' instead of 'extended release,' led to incorrect classification.
• The study underscores the risks associated with non-intuitive abbreviations for differentiating high-risk medications with varying release rates.
