Evaluation of Anemia and Iron Deficiency in French Surgical Departments: The National Multicenter Observational PERIOPES Study.

BACKGROUND

Assessment of anemia and iron deficiency before surgery is pivotal for patient blood management (PBM), but few data on current practices are available in the French context. The objective of this study was to describe anemia and iron deficiency management and blood transfusion use in surgical departments in France.

METHODS

This was a national multicenter cross-sectional study in 13 public hospitals and 3 private ones (all with an interest for PBM). Data of consecutive surgical patients from different specialties were retrieved from their chart between July 30, 2019, and December 31, 2021. Data included hemoglobin, iron workup, treatment with oral/intravenous iron or erythropoiesis-stimulating agent, and transfusions.

RESULTS

Data from 2345 patients (median age, 68 years; women, 50.9%; American Society of Anesthesiologists [ASA] physical status III-IV, 35.4%) were obtained. Only 5 centers had a formalized PBM program. At preoperative anesthesia visit, hemoglobin (Hb) level was assessed in 2112 (90.1%) patients and anemia diagnosed in 722 of them (34.2%). Complete iron workup was performed in 715 (30.5%) of the 2345 patients. Iron deficiency anemia was present in 219 (30.3%) of the 722 anemic patients. Among patients with anemia, only 217 (30.1%) of them were treated. A total of 479 perioperative blood transfusions were reported in 315 patients. Restrictive transfusion was not applied in 50% of transfusion episodes, and the single-unit red blood cell transfusion was also not frequent (37.2%).

CONCLUSIONS

Our observational study showed that preoperative anemia was frequent, but iron deficiency was often not assessed and few patients were treated. There is an urgent need for PBM implementation in these centers.
