Association Between Anemia, Bleeding, and Transfusion with Long-term Mortality Following Noncardiac Surgery.

ABSTRACT:

Background

Preoperative anemia is a well-established risk factor for short-term mortality in patients undergoing noncardiac surgery, but appropriate thresholds for transfusion remain uncertain. The objective of this study was to determine long-term outcomes associated with anemia, hemorrhage, and red blood cell transfusion in patients undergoing noncardiac surgery.

Methods

We performed a long-term follow-up study of consecutive subjects undergoing hip, knee, and spine surgery between November 1, 2008 and December 31, 2009. Clinical data were obtained from administrative and laboratory databases, and retrospective record review. Preoperative anemia was defined as baseline hemoglobin < 13 g/dL for men and < 12 g/dL for women. Hemorrhage was defined by International Classificat
