AbstractElderly patients who undergo major abdominal surgery are being in increasing numbers. Intensive care unit (ICU) survival is critical for surgical decision-making process. Activities of daily living (ADL) are associated with clinical outcomes in the elderly. We aimed to investigate the relationship between ADL and postoperative ICU survival in elderly patients following elective major abdominal surgery.We conducted a retrospective cohort study involving patients aged ≥65 years admitted to the surgical intensive care unit (SICU) following elective major abdominal surgery. Data from all patients were extracted from the electronic medical records. The Barthel Index (BI) was used to assess the level of dependency in ADL at the time of hospital admission.ICU survivors group had higher Barthel Index (BI) scores than non-survivors group (P < .001). With the increase of BI score, postoperative ICU survival rate gradually increased. The ICU survivals in patients with BI 0-20, BI 21-40, BI 41-60, BI 61-80 and BI 81-100 were 55.7%, 67.6%, 72.4%, 83.3% and 84.2%, respectively. In logistic regression, The Barthel Index (BI) was significantly correlated with the postoperative ICU survival in elderly patients following elective major abdominal surgery (OR = 1.33, 95% CI: 1.20-1.47, P = .02). The area under the receiver operating characteristic (ROC) curve of Barthel Index in predicting postoperative ICU survival was 0.704 (95% CI, 0.638-0.771). Kaplan-Meier survival curve in BI≥30 patients and BI < 30 patients showed significantly different.Activity of daily living upon admission was associated with postoperative intensive care unit survival in elderly patients following elective major abdominal surgery. The Barthel Index(BI) ≥30 was associated with increased postoperative ICU survival. For the elderly with better functional status, they could be given more surgery opportunities. For those elderly patients BI < 30, these results provide useful information for clinicians, patients and their families to make palliative care decisions.Copyright © 2021 the Author(s).
