The Novel Integrated Toolkit for Enhanced Pre-Hospital Life Support and Triage in Challenging and Large Emergencies (NIGHTINGALE) project was awarded to a consortium to design an innovative toolkit featuring different technological solutions for prehospital mass casualty incident (MCI) response. Translational science (T) methodology was undertaken to develop evidence-based guidelines for MCI response.

The consortium was divided into three work groups (WGs) MCI Triage, Prehospital Life Support and Damage Control and Prehospital Processes. Each WG previously collected data through the project T1 scoping review stage to provide the foundation for the initial T2 modified Delphi draft statements to present to WG internal focus groups for content and NIGHTINGALE study objectives. Their refined statements proceeded to WG specific external focus groups for further editing to be clear and concise for the following modified Delphi consensus rounds. Final WG statements were presented to modified Delphi experts for their consensus using the STAT59 platform with instruction to rank each statement on a seven-point linear numeric scale, where 1 = disagree and 7 = agree. Consensus amongst experts was defined as a standard deviation ≤1.0.

After three modified Delphi rounds, 18 of 24 statements attained consensus by the MCI Triage experts, eight of 25 by the Prehospital and Life Support and Damage Control experts, and 23 of 28 by the Prehospital Processes experts.

The three work groups will utilize consensus statements during the NIGHTINGALE project T3 phase to create evidence-based MCI response guidelines.
