What is the Delirium Bibliography? The searchable Delirium Bibliography page is one of our most popular features, allowing you to quickly gain access to the literature on delirium and acute care of older persons. It is primarily intended for clinicians and researchers interested in exploring these topics. The NIDUS team keeps it updated for you on a monthly basis!

- Abstract
BACKGROUND: The association between preoperative anemia and postoperative delirium (POD) is unclear. We sought to evaluate the effect of preoperative anemia on the risk of POD in elderly patients after non-cardiac surgery. METHODS: We retrospectively analyzed 62,600 patients aged over 60 years undergoing non-cardiac surgery between January 2011 and June 2019. The patients were divided into two groups according to the presence of preoperative anemia defined as hemoglobin < 13 g/L for men and < 12 g/dl for women. Anemia was further categorized into mild or moderate-to-severe anemia based on a cutoff of 11 g/dl. The primary outcome was POD within 7 d after surgery. The secondary outcomes included one- and three-year mortality after surgery. The inverse probability of treatment weighting (IPTW) method was used to adjust for confounders between the two groups. RESULTS: The overall incidence of POD was 3.9% (2,447 / 62,600) within 7 d after surgery. After IPTW, preoperative anemia was significantly associated with increased risk of POD (odds ratio [OR], 1.42; 95% CI, 1.30-1.55; P < 0.001). Also, the risk of POD increased with the severity of anemia (OR, 1.32; 95% CI, 1.18-1.47; P < 0.001 for mild anemia; and OR, 1.70; 95% CI, 1.50-1.93; P < 0.001 for moderate-to-severe anemia). This association was similar for one- and three-year mortality. CONCLUSIONS: Preoperative anemia was associated with an increased risk of POD in elderly patients after non-cardiac surgery. Further investigations are required to verify whether preoperative anemia is a modifiable risk factor for POD.
