The barriers to conducting successful ACP discussions between surgeons and patients are multifactorial. Kalbfell et al1 highlighted several of these barriers, including lack of patient efficacy, physician attitudes, and institutional values in older adults who require major surgeries. The inadequacy of patient efficacy in preoperative ACP is illustrated by findings from the primary, multisite trial of QPL intervention conducted by Schwarze et al. Interestingly, the authors found that patients who did not receive QPL brochure had no ACP discussions, and that QPL implementation did not significantly improve discussion rates despite its intent to encourage these discussions.2 Possible explanations for this lack of engagement might be a lack of health literacy or patient efficacy in the study population. Qualitative data from the current study provided further evidence to support these explanations. For instance, some patients provided limited or incomplete information about their wishes for health care management while others felt it was unnecessary to have ACP discussions unless complications arose.1 However, the latter example counters the purpose of ACP which is to enable patients to make plans about future health care and not reactive to a medical complication or emergency.
Surgeons bear a large responsibility in providing treatments that are consistent with the care goals of the patient. Thus, surgeons play a crucial role in engaging, guiding, and facilitating ACP discussions with patients. This role is even more critical when patients are unable or unwilling to initiate care goal discussions. Physician attitudes towards ACP, therefore, greatly influence the effectiveness of these discussions. In a study of self-administered surveys by vascular, neurologic, and cardiothoracic surgeons, greater than 90% of respondents viewed postoperative life-supporting therapy as necessary, and 54% would decline to operate on patients with an AD limiting life-supporting therapy.3 Moreover, the same study showed that 52% of respondents reported discussing AD before surgery, a figure that exceeded the actual rates at which ACP discussions occur in many other studies. In the current study, Kalbfell et al1 also found that surgeons viewed ACP discussions largely in the context of AD creation and declined to investigate the full scope of patient preferences. These findings, when combined with other studies that indicate an incomplete understanding of ACP in some surgeons, suggest that not all physicians are able or willing to navigate these sometimes lengthy and difficult conversations with patients. This gap in practice provides opportunities for training in surgical specialties that center on optimizing preoperative ACP discussions to meet the care needs of older patients.
Institutional value and culture are important factors that impact physician behavior and the practice of ACP discussion. In the current study, the authors reported that the majority of ACP discussions were held by a minority of surgeons and that different institutions and study sites had vastly different rates of ACP documentation.1 These results are further supported by findings of large variations between physicians and hospitals in ACP reporting in hospitalized frail older adults.4 These variations in practices at different institutions suggest that it is possible to improve rates of preoperative ACP discussion. Reasons for these differences need to be further investigated in order to identify strategies, resources, or trainings required by medical institutions to support surgeons to carry out ACP discussions with patients undergoing high-risk surgeries.
The study conducted by Kalbfell et al1 has several strengths. For example, it included Spanish-speaking patients and the use of a Spanish version of the QPL intervention to account for cultural differences. The study also included multiple surgical specialties and institutions and captured a large and national sample, thus making its findings more generalizable. However, the lack of data on the duration of preoperative consultation visits in patients who completed ACP discussions poses a limitation to this study. This is relevant because surgeon availability to engage in lengthy ACP discussions may be limited due to busy clinical schedules. Additional data on the duration of preoperative visits inclusive of a thoughtfully conducted ACP discussion could help to modify clinical workflow to facilitate its uptake in surgical practices.
Applications for Clinical Practice
The findings from the current study indicate that patients and surgeons agree that preoperative ACP discussions are beneficial to the clinical care of older adults before high-risk surgeries. However, these important conversations do not occur frequently. Surgeons and health care institutions need to identify strategies to initiate, facilitate, and optimize productive preoperative ACP discussions to provide patient-centered care in vulnerable older surgical patients.
