Objectives
Narrative objectives1
There are increasing reports from around the world that proactive interventions for anemia, starting before surgery and continuing throughout the perioperative period, have improved the outcomes of surgical patients. Currently, there are only a few reports on preoperative anemia treatment in Japan, and not enough efforts have been made yet. Therefore, to effectively intervene in preoperative anemia in the future, it is necessary to understand the status of preoperative anemia in our hospital.
