Healthcare organizations, compendia, and drug knowledge base vendors use varying methods to evaluate and synthesize evidence on drug-drug interactions (DDIs). This situation has a negative effect on electronic prescribing and medication information systems that warn clinicians of potentially harmful medication combinations. A paper by Scheife et al. (see references below) provides recommendations for systematic evaluation of evidence from the scientific literature, drug product labeling, and regulatory documents with respect to DDIs for clinical decision support. Research on this topic is ongoing and stakeholders are suggested to read the companion articles listed below.
