Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this retrospective observational study is to explore the association of perioperative blood transfusion with increased one-year mortality in patients undergoing surgeries. The main question it aims to answer perioperative blood transfusion is associated with increased one-year mortality across various surgical settings. We will retrospectively collect the clinical data (including one-year mortality) in patients with perioperative blood transfusion or not and analysis the association between perioperative blood transfusion and one-year mortality after surgery.
