Activities of daily living associated with postoperative intensive care unit survival in elderly patients following elective major abdominal surgery: An observational cohort study.

ABSTRACT:

Abstract

Elderly 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.

Project description:Background In 2020, there were 2,206,771 new cases of lung cancer worldwide, ranking first in mortality rate postoperative delirium (POD) is a common surgical complication and typically occurs 1–3 days after surgery which leads to prolonged hospital stay. The currently available research on POD in elderly patients was mainly carried out in cardiac surgery, orthopedic, and gastroenterology departments. It is necessary to study the incidence and risk factors of delirium in intensive care unit (ICU) elderly patients after lung cancer surgery. Methods This study is a single-center and singe-arm observational study which examined the incidence of and factors affecting POD in elderly patients with lung cancer in ICU at our center from September 2019 to May 2020. 22 relevant variables including arterial oxygen partial pressure, postoperative sedative drug use, and other data were collected. The Confusion Assessment Method of Intensive Care Unit was used to assess the occurrence of POD, the Chinese version of the Richards-Campbell Sleep Questionnaire was used to assess patients’ postoperative sleep quality, and the Mini-Mental State Examination was used to assess patients’ preoperative cognitive level. Univariate and multivariate logistic regression analyses were conducted to identify the factors affecting POD in elderly ICU patients with lung cancer. Results Among the 208 elderly ICU patients who underwent surgery for lung cancer, 32 (15.38%) had POD. The results showed that postoperative blood oxygen level, preoperative cognitive level score and postoperative sleep quality score in delirium group were significantly lower than those in non-delirium group (P values were 0.002, 0.000, 0.000, respectively). The proportion of previous coronary heart disease and postoperative sedation use in delirium group was significantly higher than that in non-delirium group (P=0.008 and 0.008, respectively). Conclusions It was observed that the preoperative Mini-Mental State Examination (MMSE) score and postoperative Richards-Campbell Sleep Questionnaire (RCSQ) score of the delirium group were significantly lower than those of the non-delirium group, and this trend was still observed after adjusting for influencing factors. It is suggested that the difference of cognitive level in elderly lung cancer population has a significant effect on the occurrence of POD. In clinical work, we should pay more attention to patients with preoperative cognitive impairment, hypoxic state, and postoperative sleep disturbance.

Project description:The management of acute decompensated heart failure often requires intensive care. However, the effects of early intensive care unit/coronary care unit admission on activities of daily living (ADL) in acute decompensated heart failure patients have not been precisely evaluated. Thus, we retrospectively assessed the association between early intensive care unit admission and post-discharge ADL performance in these patients. Acute decompensated heart failure patients (New York Heart Association I-III) admitted on emergency between April 1, 2014, and December 31, 2018, were selected from the Diagnosis Procedure Combination database and divided into intensive care unit/coronary care unit (ICU) and general ward (GW) groups according to the hospitalization type on admission day 1. The propensity score was calculated to create matched cohorts where admission style (intensive care unit/coronary care unit admission) was independent of measured baseline confounding factors, including ADL at admission. The primary outcome was ADL performance level at discharge (post-ADL) defined according to the Barthel index. Secondary outcomes included length of stay and total hospitalization cost (expense). Overall, 12231 patients were eligible, and propensity score matching created 2985 pairs. After matching, post-ADL was significantly higher in the ICU group than in the GW group [mean (standard deviation), GW vs. ICU: 71.5 (35.3) vs. 78.2 (31.2) points, P<0.001; mean difference: 6.7 (95% confidence interval, 5.1-8.4) points]. After matching, length of stay was significantly shorter and expenses were significantly higher in the ICU group than in the GW group. Stratified analysis showed that the patients with low ADL at admission (Barthel index score <60) were the most benefited from early intensive care unit/coronary care unit admission. Thus, early intensive care unit/coronary care unit admission was associated with improved post-ADL in patients with emergency acute decompensated heart failure admission.
