A systematic literature review on strategies to avoid look-alike errors of labels.

Purpose: Unclear labeling has been recognized as an important cause of look-alike medication errors. The aim of this literature review is to systematically evaluate the current evidence on strategies to minimize medication errors due to look-alike labels.

Methods: A literature search of PubMed and EMBASE for all available years was performed independently by two reviewers.
