Predicting blood transfusion needs in colorectal surgery at a university hospital in Saudi Arabia: insights into anemia, malnutrition, and surgical factors

Addressing these through a multidisciplinary approach and the development of perioperative protocols may reduce transfusion needs. Future prospective studies are needed to validate these findings and refine transfusion risk assessments.
