Efforts to improve the safety and quantification of iatrogenic harm in children are necessary in paediatric practice and health care. Consensus methods are a systematic means to resolve inconsistencies in scientific information. The items to be assessed are scored and/or ranked and consensus is sought in successive rounds. The aim here is to review features of the Delphi process and the nominal group technique and their use in paediatric patients.
The Delphi process and the nominal group technique are also applicable in paediatric age groups. They offer a useful choice in the selection of safety and quality improvement measures and tools.
