Effectiveness of a 'Do not interrupt' bundled intervention to reduce interruptions during medication administration: a cluster randomised controlled feasibility study.
Approach to Improving Safety
Setting of Care
This randomized controlled trial had nurses on four hospital wards wear "do not interrupt" vests during medication administration. Compared to nurses on four wards who were not asked to wear vests, the rate of interruptions experienced by the control nurses were significantly reduced. However, 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.
