Application of quality indicators and critical lessons learned assessment as a research approach for the evaluation of rescue missions during terrorist attacks.

In Wuerzburg, Germany, a terrorist attack and a killing rampage occurred five years apart (2016 and 2021). Following a structured evaluation of the rescue mission in 2016, a bundle of quality indicators and ten "lessons learned" were defined. Aim of the presented study was to compare the two rescue missions and to critically review the lessons learned from 2016 for their implementation and feasibility.
