Study Overview
Objective. The objectives of this study were to (1) quantify the frequency of preoperative advance care planning (ACP) discussion and documentation for older adults undergoing major surgery in a national sample, and (2) characterize how surgical patients and their family members considered ACP after postoperative complications.
Design. A secondary analysis of data from a multisite randomized clinical trial testing the effects of a question prompt list intervention (a Question Problem List [QPL] brochure with 11 questions) given to patients aged 60 years or older undergoing high-risk surgery on preoperative communication with their surgeons.
Setting and participants. This multisite randomized controlled trial involved 5 study sites that encompassed distinct US geographic areas, including University of Wisconsin Hospital and Clinics (UWHC), Madison; the University of California, San Francisco, Medical Center (UCSF); Oregon Health & Science University (OHSU), Portland; the University Hospital of Rutgers New Jersey Medical School (Rutgers), Newark; and the Brigham and Women’s Hospital (BWH), Boston, Massachusetts. The study enrolled 40 surgeons who routinely performed high-risk oncological or vascular surgery via purposeful sampling; patients aged 60 years or older with at least 1 comorbidity and an oncological or vascular problem that were treatable with high-risk surgery; and 1 invited family member per enrolled patient to participate in open-ended interviews postsurgery. High-risk surgery was defined as an operation that has a 30-day in-hospital mortality rate greater than or equal to 1%. Data were collected from June 1, 2016, to November 30, 2018.
Main outcome measures. The frequency of preoperative discussions and documentation of ACP was determined. For patients who had major surgery, any mention of ACP (ie, mention of advance directive [AD], health care power of attorney, or preference for limitations of life-sustaining treatments) by the surgeon, patient or family member during the audio recorded, transcribed, and coded preoperative consultation was counted. The presence of a written AD in the medical record at the time of the initial consultation, filed between the consultation and the date of surgery, or added postoperatively, was recorded using a standardized abstraction form. Postoperative treatments administered and complications experienced within 6 weeks after surgery were recorded. Open-ended interviews with patients who experienced significant postoperative complications (eg, prolonged hospitalization > 8 days, intensive care unit stay > 3 days) and their family members were conducted 6 weeks after surgery. Information ascertained during interviews focused on treatment decisions, postoperative experiences, and interpersonal relationships among patients, families, and clinicians. Transcripts of these interviews were then subjected to qualitative content analysis.
Main results. A total of 446 patients were enrolled in the primary study. Of these patients, 213 (122 men [57%]; 91 women [43%]; mean [SD] age, 72 [7] years) underwent major surgery. Only 13 (6.1%) of those who had major surgery had any discussion related to ACP in the preoperative consultation. In this cohort, 141 (66%) patients did not have an AD on file before undergoing major surgery. The presence of AD was not associated with age (60-69 years, 26 [31%]; 70-79 years, 31 [33%]; ≥ 80 years, 15 [42%]; P = .55), number of comorbidities (1, 35 [32%]; 2, 18 [33%]; ≥ 3, 19 [40%]; P = .62), or type of procedure (oncological, 53 [32%]; vascular, 19 [42%]; P = .22). Moreover, there was no difference in preoperative communication about ACP or documentation of an AD for patients who were mailed a QPL brochure compared to those who received usual care (intervention, 38 [35%]; usual care, 34 [33%]; P = .77). Rates of AD documentation were associated with individual study sites with BWH and UWHC having higher rates of documentation (20 [50%] and 27 [44%], respectively) compared to OHSU, UCSF, or Rutgers (7 [17%], 17 [35%], and 1 [5%], respectively). Analysis from the interviews indicated that patients and families felt unprepared for serious surgical complications and had varied interpretations of ACP. Patients with complications were enthusiastic about ACP but did not think it was important to discuss their preferences for life-sustaining treatments with their surgeon preoperatively.
Conclusion. Although surgeons and patients report that they believe ACP is important, preoperative discussion of patient preferences rarely occurs. This study found that the frequency of ACP discussions or AD documentations among older patients undergoing high-risk oncologic or vascular surgery was low. Interventions that are aimed to increase rates of preoperative ACP discussions should be implemented to help prepare patients and their families for difficult decisions in the setting of serious surgical complications and could help decrease postoperative conflicts that result from unclear patient care goals.
Commentary
Surgeons and patients approach surgical interventions with optimistic outlooks while simultaneously preparing for unintended adverse outcomes. For patients, preoperative ACP discussions ease the burden on their families and ensure their wishes and care goals are communicated. For surgeons, these discussions inform them how best to support the values of the patient. Therefore, it is unsurprising that preoperative ACP is viewed favorably by both groups. Given the consensus that ACP is important in the care of older adults undergoing high-risk surgery, one would assume that preoperative ACP discussion is a standard of practice among surgeons and their aging patients. However, in a secondary analysis of a randomized control trial testing a patient-mediated intervention to improve preoperative communication, Kalbfell et al1 showed that ACP discussions rarely take place prior to major surgery in older adults. This finding highlights the significant discrepancy between the belief that ACP is important, and the actual rate that it is practiced, in older patients undergoing high-risk surgery. This discordance is highly concerning because it suggests that surgeons who provide care to a very vulnerable subset of older patients may overlook an essential aspect of preoperative care and therefore lack a thorough and thoughtful understanding of the patient’s care goals. In practice, this omission can pose significant challenges associated with the surgeon and family’s decisions to use postoperative life-sustaining interventions or to manage unforeseen complications should a patient become unable to make medical decisions.
