Preoperative functional status is associated with discharge to nonhome in geriatric individuals

INTRODUCTION

Discharging older individuals to rehabilitation facilities is associated with adverse outcomes, including readmission or increased mortality rate. As preoperative functional status is an important factor impacting patient outcome, we hypothesized that this would be associated with patient disposition to nonhome locations.

MATERIALS AND METHODS

A retrospective analysis was performed using data from the 2013-2018 American College of Surgeons National Surgical Quality Improvement Program, including targeted variables from the Geriatric Pilot Project. Patients aged 65 and older in 33 institutions across the nation were included (n = 44,219). Preoperative functional status was categorized as independent, partially dependent, and dependent. The primary outcome was home versus nonhome disposition. Nonhome was defined as rehabilitation facility and nursing home. Descriptive analyses were performed. Variables associated with postoperative discharge to nonhome were identified using logistic regression.

RESULTS

The largest percentage of operations was orthopedics (40.8%), followed by general surgery (29.2%) and vascular operations (10.0%). The majority of the patients were independent before operations (93.1% independent, 6% partially dependent, and 0.9% totally dependent). In regression analyses, patients who were partially dependent preoperatively had five times higher odds of discharging to nonhome, compared to patients who were independent (odds ratio [OR] 5.04, p < 0.01). Similarly, patients who were totally dependent had 3.2 higher odds of discharging to nonhome than patients who were independent (OR 3.22, p < 0.01).

CONCLUSION

Better preoperative functional status is associated with patient discharge to home in older adults. Preoperative interventions aimed at improving functional status, such as prehabilitation, may be beneficial in improving patient outcomes.

Preoperative Immune-Nutritional Abnormality Predicts Poor Outcome in Elderly Non-Small-Cell Lung Cancer Patients with Comorbidities

Background: Elderly non-small-cell lung cancer (NSCLC) patients are increasing. In general, elderly patients often have more comorbidities and worse immune-nutritional condition.

Patients and methods: In total, 122 NSCLC patients aged 75 years or older, underwent thoracic surgery between January 2007 and December 2010. In all, 99 of 122 patients (81.1%) who had preoperative comorbidities were retrospectively analyzed. We evaluated the preoperative immune-nutritional condition using the controlling nutritional status (CONUT) score.

Results: We decided the best cutoff value for CONUT score was 1; as a result, 42 of 99 patients (42.4%) had abnormal preoperative CONUT score. Univariate analyses showed sex (P = 0.0099), smoking status (P = 0.0176), pathological stage (P = 0.0095), and preoperative CONUT score (P = 0.0175) significantly affected overall survival (OS). In multivariate analysis, pathological stage (relative risk (RR): 2.12; 95% confidence interval (CI): 1.10–3.90; P = 0.0268) and preoperative CONUT score (RR: 2.10; 95% CI: 1.20–3.67; P = 0.0094) were shown to be independent prognostic factors. In Kaplan–Meier analysis of OS, the preoperative abnormal CONUT score group had significantly shorter OS than did the preoperative normal CONUT score group (P = 0.0152, log-rank test); however, there were no statistical differences both in disease-free survival (DFS) and cancer-specific survival (CSS; P = 0.9238 and P = 0.8661, log-rank test, respectively). In total, 22 patients (46.8%) were dead caused by other diseases such as pneumonia or other organs malignancies.

Conclusion: Preoperative abnormal CONUT score is a poor prognostic factor for the elderly NSCLC patients with preoperative comorbidities and might predict poor postoperative outcome caused by not primary lung cancer but other diseases.

Preoperative Comorbidities and Outcomes of Medically Complex Living Kidney Donors

Introduction

Recent reports have described an increased risk of renal disease in living kidney donors compared with the general population. However, these reports do not detail the outcomes of medically complex living donors (MCLDs) with preoperative comorbidities (PCs), such as hypertension, dyslipidemia, glucose intolerance, and obesity. Analysis of living donors with end-stage renal disease (ESRD) has shown that these PCs may contribute significantly to the development of ESRD. We aimed to evaluate the effect of PCs on postoperative renal function and mortality in MCLDs.

Methods

Between January 2008 and December 2016, 807 living-donor kidney transplants were performed in our unit. Of these, 802 donors completed postoperative follow-up of >5 months. Donors were stratified into 4 groups based on the number of PCs present: healthy living donors (HLDs) with no PCs (n = 214) or MCLDs with 1 PC (n = 302), 2 PCs (n = 196), or 3 PCs (n = 90) (denoted MCLD [PC 1], MCLD [PC 2], or MCLD [PC 3], respectively). We compared pathology observation data from baseline biopsy, postoperative estimated glomerular filtration rate (eGFR), postoperative urinary protein concentration, and mortality between HLD and MCLD groups.

Results

Interstitial fibrosis, tubular atrophy, glomerulosclerosis, and arteriolosclerosis were more frequent in MCLDs (PC 3) than in HLDs. No significant differences were identified between HLDs and MCLDs in terms of postoperative eGFR and short-term mortality. Overt proteinuria and ESRD were not observed.

Conclusions

Appropriate postdonation management of MCLDs with PCs may result in similar outcomes as for HLDs.
