Study Overview
Objective. The objective of this study was to evaluate orders and documentation describing perioperative management of code status in adults.
Design. A retrospective case series of all adult inpatients admitted to hospitals at 1 academic health system in the US.
Setting and participants. This retrospective case series was conducted at 5 hospitals within the University of Pennsylvania Health System. Cases included all adult inpatients admitted to hospitals between March 2017 and September 2018 who had a Do-Not-Resuscitate (DNR) order placed in their medical record during admission and subsequently underwent a surgical procedure that required anesthesia care.
Main outcome measures. Medical records of included cases were manually reviewed by the authors to verify whether a DNR order was in place at the time surgical intervention was discussed with a patient. Clinical notes and DNR orders of eligible cases were reviewed to identify documentation and outcome of goals of care discussions that were conducted within 48 hours prior to the surgical procedure. Collected data included patient demographics (age, sex, race); case characteristics (American Society of Anesthesiologists [ASA] physical status score, anesthesia type [general vs others such as regional], emergency status [emergent vs elective surgery], procedures by service [surgical including hip fracture repair, gastrostomy or jejunostomy, or exploratory laparotomy vs medical including endoscopy, bronchoscopy, or transesophageal echocardiogram]); and hospital policy for perioperative management of DNR orders (written policy encouraging discussion vs written policy plus additional initiatives, including procedure-specific DNR form). The primary outcome was the presence of a preoperative order or note documenting code status discussion or change. Data were analyzed using χ2 and Fisher exact tests and the threshold for statistical significance was P < .05.
Main results. Of the 27 665 inpatient procedures identified across 5 hospitals, 444 (1.6%) cases met the inclusion criteria. Patients from these cases aged 75 (SD 13) years (95% CI, 72-77 years); 247 (56%, 95% CI, 55%-57%) were women; and 300 (68%, 95% CI, 65%-71%) were White. A total of 426 patients (96%, 95% CI, 90%-100%) had an ASA physical status score of 3 or higher and 237 (53%, 95% CI, 51%-56%) received general anesthesia. The most common procedures performed were endoscopy (148 [33%]), hip fracture repair (43 [10%]), and gastrostomy or jejunostomy (28 [6%]). Reevaluation of code status was documented in 126 cases (28%, 95% CI, 25%-31%); code status orders were changed in 20 of 126 cases (16%, 95% CI, 7%-24%); and a note was filed without a corresponding order for 106 of 126 cases (84%, 95% CI, 75%-95%). In the majority of cases (109 of 126 [87%], 95% CI, 78%-95%) in which documented discussion occurred, DNR orders were suspended. Of 126 cases in which a discussion was documented, participants of these discussions included surgeons 10% of the time (13 cases, 95% CI, 8%-13%), members of the anesthesia team 51% of the time (64 cases, 95% CI, 49%-53%), and medicine or palliative care clinicians 39% of the time (49 cases, 95% CI, 37%-41%).
The rate of documented preoperative code status discussion was higher in patients with higher ASA physical status score (35% in patients with an ASA physical status score ≥ 4 [55 of 155] vs 25% in those with an ASA physical status score ≤ 3 [71 of 289]; P = .02). The rates of documented preoperative code status discussion were similar by anesthesia type (29% for general anesthesia [69 of 237 cases] vs 28% [57 of 207 cases] for other modalities; P = .70). The hospitals involved in this study all had a written policy encouraging rediscussion of code status before surgery. However, only 1 hospital reported added measures (eg, provision of a procedure-specific DNR form) to increase documentation of preoperative code status discussions. In this specific hospital, documentation of preoperative code status discussions was higher compared to other hospitals (67% [37 of 55 cases] vs 23% [89 of 389 cases]; P < .01).
Conclusion. In a retrospective case series conducted at 5 hospitals within 1 academic health system in the US, fewer than 1 in 5 patients with preexisting DNR orders had a documented discussion of code status prior to undergoing surgery. Additional strategies including the development of institutional protocols that facilitate perioperative management of advance directives, identification of local champions, and patient education, should be explored as means to improve preoperative code status reevaulation per guideline recommendations.
