Peripheral perfusion index stratifies risk in patients with intraoperative anemia: A multicentre cohort study
Authors' conclusion
High PPI in acute surgical patients who also presents with anemia was associated with a significantly better outcome when compared with patients with both low PPI and anemia.

Main finding
As reported in the abstract
Estimate (CI)
Low PPI and low Hb90-day severe postoperative complications; highest of the PPI/Hb subgroups
aOR 2.95(1.62–5.45)
Low PPI and low Hb90-day mortality; highest of the PPI/Hb subgroups
aOR 3.13(1.45–7.11)
Low PPI and low Hb vs High PPI and low Hb90-day mortality; significantly higher
OR 8.6(1.57–162.10)
- 90-day mortality, whole cohort
- 21% (n = 154)
- Severe postoperative complications, whole cohort
- 31% (n = 231)
