Prescriber Perceptions of a Near Real-Time Fax Alert Program for Potential Drug-Drug Interactions

BACKGROUND: Health systems have developed interventions to reduce harm associated with drug-drug interactions. Pharmacy benefit managers are in an important position to identify the coprescribing of medications known to interact, since they process data on a large portion of prescription claims in the United States. Electronic health records and electronic prescribing also include alerts through their systems’ clinical decision support.
