How to implement of patient blood management pillar 1: An Italian expert opinion based on a "bundles" approach.

Worldwide iron anemia is a common disorder with a significant economic burden on health-care systems. Red blood cell transfusion is the mainstay to correct anemia in surgical settings, but it is also an overused procedure and recent data support its possible role in worsening patient outcomes. Patient Blood Management (PBM) is a multidisciplinary approach to optimize hemostasis, manage anemia, minimize iatrogenic blood loss, and improve tolerance to anemia. The present paper aims to provide a "bundles" approach, based on several preoperative anemia management measures, to implement PBM Pillar 1 in clinical practice.
