An error in prescribing, dispensing or administering of a drug, irrespective of whether such errors lead to adverse consequences or not [1,2].
Parenteral medication errors are a serious safety problem in Intensive Care Units (ICU) and are recognized as a high priority health care issue1,2. Errors have been shown to be associated with additional morbidity and mortality in an already critically ill population 3,4. In their recently published multinational, observational and cross sectional study, Valentin et al. demonstrated that parenteral medication errors represent a common pattern across national borders, different ICU-settings and health care systems5. The Institute of Medicine estimated that in hospitals “a typical patient would be subject to one administration medication error per day”6.
