Haemoglobin levels and outcomes of subgroups of patients with pre-operative anaemia based on red cell size: A retrospective cohort study.
Pre-operative anaemia is common and associated with adverse outcomes. We hypothesised that pre-operative anaemia would be evident more than 1 month pre-operatively, and that peri-operative changes in haemoglobin and post-operative outcomes differed between red cell size-based subsets of anaemia. ⋯ Pre-operative anaemia is evident long prior to the procedure and its association with worse outcomes is similar regardless of red cell size.
