Relationship Between Newly Established Perioperative DNR Status and Perioperative Outcomes in the Elderly Population: A NSQIP Database Analysis

Comprehensive geriatric assessment as an essential tool to register or update DNR codes in a tertiary care hospital

PURPOSE

To investigate the prevalence of Do not Resuscitate (DNR) code registration in patients with a geriatric profile admitted to Antwerp University Hospital, a tertiary care hospital in Flanders, Belgium, and the impact of comprehensive geriatric assessment (CGA) on DNR code registration.

PATIENTS AND METHODS

Retrospective analysis of a population of 543 geriatric patients (mean age 82.4 ± 5.19 years, 46.4% males) admitted to Antwerp University Hospital from 2018 to 2020 who underwent a CGA during admission. An association between DNR code registration status before and at hospital admission and age, gender, ethnicity, type of residence, clinical frailty score (CFS), cognitive and oncological status, hospital ward and stay on intensive care was studied. Admissions before and during the first wave of the pandemic were compared.

RESULTS

At the time of hospital admission, a DNR code had been registered for 66.3% (360/543) of patients. Patients with a DNR code at hospital admission were older (82.7 ± 5.5 vs. 81.7 ± 4.6 years, p = 0.031), more frail (CFS 5.11 ± 1.63 vs. 4.70 ± 1.61, p = 0.006) and less likely to be admitted to intensive care. During the hospital stay, the proportion of patients with a DNR code increased to 77% before and to 85.3% after CGA (p < 0.0001). Patients were consulted about and agreed with the registered DNR code in 55.8% and 52.1% of cases, respectively. The proportion of patients with DNR codes at the time of admission or registered after CGA did not differ significantly before and after the start of the COVID-19 pandemic.

CONCLUSION

After CGA, a significant increase in DNR registration was observed in hospitalized patients with a geriatric profile.

The Do Not Resuscitate (DNR) order in the perioperative setting: practical considerations

PURPOSE OF REVIEW

Addressing patients' Do Not Resuscitate (DNR) status in the perioperative setting is important for shared patient decision-making. Although the inherently resuscitative nature of anesthesia and surgery may pose an ethical quandary for clinicians tasked with caring for the patient, anesthesiologist-led efforts need to evaluate all aspects of the DNR order and operative procedures.

RECENT FINDINGS

Approximately 15% of patients undergoing surgical procedures have a preexisting DNR order (Margolis et al., 1995) [1]. American Society of Anesthesiologists (ASA) and the American College of Surgeons (ACS) do not support automatic reversal of the DNR order in the perioperative setting. Citing patient self-determination and autonomy, these societies advocate for a thoughtful discussion where a patient or legal designee may make an informed decision regarding resuscitation in the perioperative setting. Although studies have suggested increased perioperative mortality among patients with a preexisting DNR order, this data remains largely inconclusive.

SUMMARY

Efforts must be made to address the DNR order in the perioperative setting. The fundamental tenets of medical ethics, nonmaleficence, beneficence, and patient autonomy can help to guide this oftentimes challenging discussion.
