Effectiveness of a 'Do not interrupt' bundled intervention to reduce interruptions during medication administration: a cluster randomised controlled feasibility study.

Westbrook JI, Li L, Hooper TD, et al. BMJ quality & safety. 2017;26:734-742.

This randomized controlled trial had nurses on four hospital wards wear "do not interrupt" vests during medication administration. The rate of interruptions the intervention nurses experienced was compared to the rate in four control wards that did not have nurses wear vests. Although the intervention reduced non–medication-related interruptions, nurses reported that the vests were time consuming and uncomfortable; less than half would support continuing the intervention. This study demonstrates the need to design and test sustainable interventions to improve patient safety.
