ESI Rx History™

Electronic Medication History for Transitions of Care

Performing accurate medication reconciliation is a critical element of a successful point-of-care transition. Today’s medication reconciliation process relies on time-consuming patient interviews, which can result in manual transcription errors and unreported medications, putting patients at risk of adverse drug events (ADEs) and associated hospital readmissions. To do the job well, care providers need the right information at the right time and in the right format.

To help care providers better manage patient risk, advance patient safety and improve the medication reconciliation process, ESI Rx History™ was developed to electronically deliver patients’ medication history in real-time at the point of care. As a proven and reliable solution for medication reconciliation, ESI Rx History enables a single reconciled medication history to exist throughout the continuum of care, supporting a more informed approach to treatment, helping to reduce a patient’s risk of costly ADEs and readmissions.
