Identifying Prevalence and Potential Predictors of Do-Not-Attempt-Resuscitation Orders to Facilitate Preoperative Discussions on Code Status

Background Do Not Attempt Resuscitation (DNAR) orders allow patients with life-threatening conditions to decline resuscitation efforts should the need arise. The American Society of Anesthesiologists (ASA) recommends discussions with patients on their code status to clarify and honor their goals of care perioperatively. This project sought to determine the prevalence of DNAR orders and to identify the demographics and potential clinical predictors of DNAR status at the beginning and end of admission, which would help anesthesiologists at our center facilitate these discussions. Methods Factors associated with DNAR status at beginning and at end of hospital stay were determined through univariate logistic regressions. For DNAR status at beginning and end of hospital admission, variables assessed were age at arrival, race, sex, palliative consult, use of palliative care service, length of stay in days, presence of surgery, presence of emergent surgery, care level, and medical service. Results Approximately 2.4 percent of the sample had an active DNAR order at the beginning of their hospital admission compared to 7.4 percent at the end of hospital admission. Factors significantly associated with DNAR status at the beginning of the hospital stay were consistent with prior literature (age, palliative care consult or service). However, factors significantly associated with DNAR status at the end of hospital stay that were notable included length of stay, undergoing emergent surgery, higher level of care, and being on the oncology service and medical respiratory intensive care unit. Conclusions This retrospective study allows anesthesiologists at our institution to identify patients who may benefit from a more comprehensive perioperative discussion about code status based on certain clinical characteristics, which may improve quality of care by preventing unwanted resuscitative measures that do not align with a patient’s goals of care.
