Restrictive Transfusion in Geriatric Trauma Patients.

Area of Science:

• Trauma surgery
• Geriatric medicine
• Hematology

Background:

• Elderly trauma patients often have comorbidities, increasing transfusion risks.
• Optimal red blood cell transfusion thresholds in this population remain debated.

Purpose of the Study:

• To evaluate the safety and outcomes of a restrictive red cell transfusion strategy versus a liberal strategy in elderly trauma patients.
• To determine if restrictive transfusion reduces complications and length of stay.

Main Methods:

• Retrospective study of elderly (≥70 years) trauma patients from 2005-2013.
• Inclusion criteria: hemoglobin < 10 g/dL within 48 hours, Injury Severity Score ≤ 25, no active cardiac ischemia.
• Comparison between liberal (transfused for Hg < 10 g/dL) and restrictive (transfused for Hg < 7 g/dL) groups.

Main Results:

• 382 patients included: 229 liberal, 153 restrictive.
• Higher complication rates in the liberal group (52% vs 32%, P=0.0001).
• Transfusion independently increased complication risk (OR=2.3). Liberal group had longer hospital (9 vs 7 days) and ICU (2 vs 1 day) stays. No mortality difference (3% vs 4%).

Conclusions:

• Restrictive red cell transfusion is safe in elderly trauma patients.
• It may be associated with fewer complications and shorter hospitalizations.
• This strategy warrants consideration for optimizing care in this demographic.
