Abstract

Background Postoperative delirium (POD) is a frequent yet underestimated neurocognitive complication following hip fracture surgery, particularly among older adults. While anemia is a prevalent and potentially modifiable nutritional disorder in this population, but its impact on POD remains uncertain. We aimed to examine the association between perioperative anemia and POD risk in older adults undergoing surgical treatment for intertrochanteric fractures (ITF). Methods We conducted a multicenter retrospective cohort study of elderly patients with ITF who underwent surgical fixation in China. Patients were categorized by their nadir perioperative hemoglobin (Hb): ≥103 g/L, 75–
