An observational feasability study of a new anaesthesia drug storage tray. Anaesthesia 2018 anae.14187 DS Almghaibi et al   https://onlinelibrary.wiley.com/doi/pdf/10.1111/anae.14187 Rainbow TraysTM  were tested against current practice to demonstrate that it is feasable to introduce a new colour coded compartmentalised Rainbow Tray into clinical practice. Findings included a perception of ease of use by aiding drug identification through colour coded compartmentalisation.

Evaluation of perioperative Medication Errors and Adverse Drug Events. Anaesthesiology 2016; 124:25-34 Karen C Nanji et al. http://anesthesiology.pubs.asahq.org/article.aspx?articleid=2466532 This study examines the rates for perioperative medication error in anaesthesia and through observation finds that a rate of 1 in 20 administrations and every second operation resulted in a medication error and/or adverse drug event.
AAGBI and RCoA syringe labelling in critical care areas using the ISO25826 international standard for background colours for user applied syringe drug labels.
