Palliative Care Consults and Frailty Screening in High-Risk Vascular Surgery Patients

Abstract

Palliative care has increasingly been integrated into the management of high-risk surgery because of the beneficial effect on patient quality of life. However, the utilization of palliative care in vascular surgery remains unclear due to a lack of data. The purpose of this study was to determine the palliative care consult rate in high-risk vascular surgery patients. A retrospective chart review was performed at a single Veteran Affairs Medical Center from 2013 to 2021. High-risk vascular surgery patients were identified by using the Veterans Affairs Surgical Quality Improvement Program (VASQIP) risk score of >4%, which predicted 30-day mortality. Patient demographics, operative procedures, and clinical outcomes were collected. A total of 126 patients underwent a high-risk vascular surgery operation. The surgical procedures consisted of 78 amputations, 19 bypasses, 18 endovascular aneurysm repair/stents, and 11 thrombectomy/arterial repair. Palliative care was consulted in 44 patients (35%) during the hospitalization: 8 patients (18%) had preoperative consults, whereas 36 patients (82%) had postoperative consults. The overall 30-day mortality was 15%, and the 1-year mortality rate was 34%. The 30-day and 1-year mortality rates were higher in those patients who received palliative care consultation (36% and 64%, respectively) compared with those without consult (0% and 21%, respectively). The palliative care consults had a higher referral rate in more frail patients, by Revised Analysis Index (RAI): n = 13 of 57 (23%) nonfrail (RAI <20), n = 14 of 44 (32%) frail (RAI = 21-32), and n = 17 of 25 (68%) very frail (RAI >33). The majority of the palliative care consults were obtained for goals of care discussion (80%) compared with withdrawal of care (20%). Palliative care is generally underused for vascular surgery patients, but our data demonstrated a palliative care consult rate of 35% in high-risk vascular surgery patients. A frailty screening program can further stratify high-risk vascular surgery patients who would benefit from an early palliative care consult.
