BACKGROUND:Consenting to do-not-resuscitate(DNR)orders is an important and complex medical decision-making process in the treatment of patients at the end-of-life in emergency departments(EDs).The DNR decision in EDs has not been extensively studied,especially in the Chinese mainland.METHODS:This retrospective chart study of all deceased patients in the ED of a university hospital was conducted from January 2017 to December 2019.The patients with out-of-hospital cardiac arrest were excluded.RESULTS:There were 214 patients’deaths in the ED in the three years.Among them,132 patients were included in this study,whereas 82 with out-of-hospital cardiac arrest were excluded.There were 99(75.0%)patients’deaths after a DNR order medical decision,64(64.6%)patients signed the orders within 24 hours of the ED admission,68(68.7%)patients died within 24 hours after signing it,and 97(98.0%)patients had DNR signed by the family surrogates.Multivariate analysis showed that four independent factors infl uenced the family surrogates’decisions to sign the DNR orders:lack of referral(odds ratio[OR]0.157,95%confi dence interval[CI]0.047–0.529,P=0.003),ED length of stay(ED LOS)≥72 hours(OR 5.889,95%CI 1.290–26.885,P=0.022),acute myocardial infarction(AMI)(OR 0.017,95%CI 0.001–0.279,P=0.004),and tracheal intubation(OR 0.028,95%CI 0.007–0.120,P<0.001).CONCLUSIONS:In the Chinese mainland,the proportion of patients consenting for DNR order is lower than that of developed countries.The decision to sign DNR orders is mainly affected by referral,ED LOS,AMI,and trachea intubation.
