What the trial is, and whether it could suit you

The goal of this observational study focuses on the effect of different preoperative anemia status on perioperative complications in patients under moderate- to high-risk surgery. Different anemia types conclude iron-deficiency anemia(IDA), anemia of chronic disease/anemia of inflammation(ACD/AI), and combined anemia.The main question it aims to answer is whether there is a difference in the incidence of complication related to oxygen supply and demand imbalance in patients with IDA, ACD/AI or combined anemia. Patients without preoperative anemia will be recruited as the control group for secondary outcome analysis, which is whether there is a difference in the incidence of complication related to oxygen supply and demand imbalance in patients with or without anemia.
