Verweij L, Smeulers M, Maaskant JM, et al. Quiet please! Drug round tabards: are they effective and accepted? A mixed method study. J Nurs Scholarsh. 2014;46(5):340-8. doi:10.1111/jnu.12092.
This study used direct observation and interviews to evaluate the effectiveness of tabards, do-not-disturb signs worn by registered nurses dispensing medications in inpatient settings, in preventing disruptions. The authors found a decrease in interruptions and medication errors, suggesting that tabards may augment safety despite controversy regarding their use.
