The last decade (2010-2019) has seen calls to action to improve the prescribing practice of junior doctors. An in-depth investigation into the causes of prescribing errors by foundation trainees in relation to their medical education (the EQUIP study) in the UK reported a prescription error rate of 8.9% for all prescribed medicines, and although that is a UK study, there are similarities with New Zealand prevocational training programmes. The EQUIP study revealed that existing teaching strategies are not working. To believe a single intervention will prevent most prescribing errors is simplistic, and for improvement to occur, new prescribers need to learn from their mistakes. Traditionally, the education of junior doctors has focused on their competence and professional registration requirements. Working in healthcare is collective and multidisciplinary, and errors occur through human and system factors.
