Incidence and factors associated with newly implemented do‐not‐attempt‐resuscitation orders among deteriorating patients after rapid response system activation: A retrospective observational study using a Japanese multicenter database

Abstract

Our data highlight the incidence and factors associated with new do‐not‐attempt‐resuscitation (DNAR) orders in 29 facilities involving 7904 patients with rapid response system (RRS) activation for clinical deterioration in Japan. We found that new DNAR orders were implemented for one in eighteen patients without pre‐DNAR orders after RRS activation. Factors associated with new DNAR orders were age, malignancy, postoperative status, and National Early Warning Score 2
