Sociodemographic Factors Associated with Do-Not-Resuscitate Order Utilization in the Surgical Intensive Care Unit: An Observational Study

The use of a do-not-resuscitate (DNR) order is a powerful tool in outlining end-of-life care. This study explores sociodemographic factors associated with selection of a DNR order and assigning a healthcare proxy in the Surgical Intensive Care Unit (SICU). A retrospective chart review of 312 patients who expired in the SICU over a 7-year period was conducted. We analyzed the association of sociodemographic factors to selection of a DNR order and assignment of a healthcare proxy. Year of admission, age, religion, and proxy were independently associated with selection of DNR. In particular, the relative chance of a DNR selection in 2019 compared to 2012 was 3.538 (95% CL = 2.001-6.255, P < .01). There are significant sociodemographic factors that influence DNR utilization, highlighting the need to consider the social and religious backgrounds when engaging patients and their families in end-of-life care. Future studies will need to be conducted on whether these sociodemographic factors influence surviving patients as this study's findings can only be applied to those who have expired.
