Haemoglobin levels and outcomes of subgroups of patients with pre‐operative anaemia based on red cell size: A retrospective cohort study
Authors' conclusion
Pre-operative anaemia is evident long prior to the procedure and its association with worse outcomes is similar regardless of red cell size.
Study context
- Population
- Adults ≥18 years undergoing first surgery at Landspitali, January 2006–December 2018, with haemoglobin (Hb) measured within 30 days before surgery10,505 (25.6%) anaemic
- Participants
- 40,979 adults
- Exposure
- Microcytic vs Normocytic vs Macrocytic vs No anaemia
- Microcyticn = 1,089
- Normocyticn = 9,243
- Macrocyticn = 173
- Outcome
- Pre-operative anaemia subgroups by red cell size
Methodological detailssingle-centre
