Editor,

We are grateful to Dr Webster for his letter1 in connection with our article on the European Board of Anaesthesiology (EBA) Medication Guidelines First update.2 His detailed clarification about the estimating and reporting of error rates is particularly useful. We congratulate his group on their original study3 and continuing work on this important issue.

We agree with his comments about observational studies but would mention another by Yang et al.4 that looked at Human Factors associated with Medication Delivery during anaesthesia and showed that prefilled syringes are superior to self-filled syringes in terms of the simplified work processes and the reduced number of system violations and associated risks. The EBA guidelines already recommend that prefilled syringes should be used whenever possible.

It is also reassuring that his group's accurate data from a recent study has produced evidence of significant safety benefits with the use of the international ISO 26286 coloured coded labels5 reducing the more harmful between-class drug errors, another recommendation from the EBA guidelines.
