- Abstract
Purpose: Preoperative malnutrition is associated with postoperative complications, prolonged intensive care unit stay, and mortality, leading to functional disability after non-cardiac surgery. However, its effects on cardiac and thoracic aortic surgery outcomes remain unknown. We examined the effects of preoperative malnutrition on disability-free survival after surgery and assessed the perioperative 12-item World Health Organization Disability Assessment Schedule 2.0 (WHODAS2.0) score based on the preoperative nutritional status. Methods: We included individuals aged ≥ 55 years who underwent elective cardiac and/or thoracic aortic surgery between April 1, 2016 and December 28, 2018 in a tertiary center. The nutritional status was assessed preoperatively using the Mini Nutritional Assessment Short Form, with scores < 12 points indicating a poor nutritional status. The JapanSCORE2 was calculated for surgical risk prediction. Our primary outcome was disability-free survival 1 year after surgery (WHODAS2.0 score: < 16%). The odds ratio of poor nutritional status for disability-free survival was calculated using multiple logistic regression analysis after adjusting for age, JapanSCORE2, and duration of surgery. Results: One hundred patients were followed up for 1 year. Preoperatively, 41 of them had a poor nutritional status. The disability-free survival rates 1 year postoperatively were 46.3% (19/41) and 64.4% (38/59) in patients with and without poor preoperative nutritional status, respectively. The adjusted odds ratio of poor nutritional status for disability-free survival at 1 year after surgery was 0.42 (95% confidence interval, 0.17–0.99). Conclusion: Patients with a poor preoperative nutritional status had less likely to show disability-free survival 1 year after cardiac and thoracic aortic surgery.
