In Reply We agree with Dr Zimmerman and colleagues about the need for a more comprehensive process of medication reconciliation, and there is substantial overlap between the approach we presented in our Viewpoint and the vision they describe. They also emphasize the importance of standardized nomenclature to refer to medication reconciliation, lest a variety of terms for the same concept impede the ability to study and improve it. It is certainly possible that variable terminology may cause confusion, although we think it would be better for an authoritative guideline or policy paper (such as by a government agency) to suggest a unifying terminology.
