Efforts toward standardization remain an important mechanism to address safety issues, such as with wristband use and drug labeling and package design. This study assessed the impact of different drug label information on injectable drug selection errors. Investigators provided three formats for conveying the concentration, quantity, and volume of a drug and evaluated the frequency of errors committed through a simulated exercise. They discovered significantly lower error rates with one of the formats in particular and call for regulatory bodies to implement standards on how such information should be displayed on injection drug labels.
