Implementation of a custom alert to prevent medication-timing errors associated with computerized prescriber order entry.

Idemoto LM, Williams BL, Ching JM, et al. American journal of health-system pharmacy : AJHP : official journal of the American Society of Health-System Pharmacists. 2015;72:1481-8.

This study examined the effect of a custom alert intended to reduce medication-timing errors associated with introduction of computerized provider order entry, which can lead to too-frequent or missed doses of medications. Using a rigorous interrupted time-series design, researchers found fewer medication-timing errors after implementation of this alert. This work demonstrates how custom alerts developed by clinicians can harness the electronic health record to improve safety.
