Anaemia is a common finding in patients presenting for major elective surgery and is associated with poor outcomes including death and complications. Iron deficiency is the leading cause of perioperative anaemia. Intravenous (i.v.) iron is considered to be an effective and safe treatment for iron deficiency anaemia and is recommended by expert opinion for treatment of preoperative anaemia, although evidence from clinical trials is lacking. ⋯ In the context of already widespread adoption of preoperative i.v. iron therapy, many clinicians may have felt they lacked equipoise. In light of the PREVENTT study routine use of i.v. iron in patients undergoing elective abdominal surgery cannot be recommended. Further research should define the optimum red cell transfusion strategy for patients undergoing surgery and idenify other surgical groups who may benefit from this intervention.

Perioperative cardiovascular guidelines endorse functional capacity estimation, based on 'cut-off' daily activities for risk assessment and climbing two flights of stairs to approximate 4 metabolic equivalents. We assessed the association between self-reported functional capacity and postoperative cardiac events. ⋯ INCT 02573532.
