1. New adverse event terminologies to be implemented in the European incident reporting system During the past number of years, the International Medical Device Regulators Forum (IMDRF) ( has developed and published new terms and codes for adverse event reporting. It is anticipated that this internationally harmonised terminology will improve stakeholders ability to conduct detection, description, analysis of and information exchanges relating to risks and failures associated with medical devices an in vitro diagnostic medical devices, enabling faster responses by industry and authorities. Notably, the word ‘adverse event’ in the present context includes (serious) incident as defined in the EU (MDR art 2. definition 65, IVDR art 2. definition 68).
