Addressing the risk of look-alike, sound-alike medication errors: bending metal or twisting arms?
What should we do in order to improve quality and safety in medicines management? How beneficial is it to design the medicines management system—for example, the tasks, tools and physical environment—to support effective working versus making people adapt to the systems in which they find themselves? As Sanders and McCormick1 put the question: is it better (more convenient, more cost-effective, more appealing) to bend metal or to twist arms?
This question arises when considering, among other problems in healthcare delivery, that of confusing look-alike, sound-alike (LASA) medicine names, which persists as a threat to medication safety despite much discussion and examination.2 Various measures have been suggested to minimise the risk of LASA medication errors in the pharmacy setting, including education of pharmacy staff, procedural controls and medicines labelling,3 4 although with no silver bullet identified so far.5 6
