Nursing implications of an early warning system implemented to reduce adverse events: a qualitative study.

Early warning systems (EWS) use patient data from the electronic health record to alert clinicians to potential patient deterioration. Twelve months after a new EWS was implemented in one hospital, nurses were interviewed to gather their perspectives on the program experience, utility, and implementation. Six themes emerged: timeliness, lack of accuracy, workflow interruptions, actionability of alerts, underappreciation of core nursing skills, and opportunity cost.
