Despite colour coded label use, syringe swap errors during administration of anaesthetic drugs remains a frequent and potentially serious cause of harm. We developed and explored the concept of a straightforward device which can be fitted to existing syringes, that employs colour and raised elements (or detents) to provide visual, haptic and auditory cues to supplement the visual cues provided by standard drug labelling. This might help to differentiate for example syringes containing vasoactive drugs from other syringes. We created six embodiments of the device, and performed a randomised unblinded study with 14 volunteers to identify those functional characteristics which met with the approval of the majority of participants. We evaluated which mechanical characteristics produced adequate haptic feedback without excessive resistance to injection. The best of the six designs was identified, which required the user to exert a mean (SD) force of ~20 (7) N to overcome the resistance of the syringe detents. The majority of volunteers were of the opinion that a device of this type would be helpful in reducing the incidence of syringe substitution error. Further research is needed to assess the efficacy of a device of this type in the clinical environment.
