Measure ID

Percentage of adult patients with a post transfusion hemoglobin or hematocrit value greater than or equal to 10 g/dL or 30%.

Measure Type
Available for Provider Feedback

The American Association of Blood Banks (AABB) recommends a transfusion threshold of hemoglobin concentration less than or equal to 8 g/dL or when patient is symptomatic (chest pain, orthostatic hypotension, tachycardia unresponsive to fluid resuscitation, or congestive heart failure).1,2 Furthermore, blood transfusions in non-cardiac surgery have been associated with increased risk of 30-day mortality and morbidity.3,4

Although the literature is not conclusive on the exact hemoglobin concentration that requires transfusion, the evidence is clear that use of fewer RBC transfusions reduces cost and risk for adverse effects of transfusion, and that transfusion to  hemoglobin value greater than 10 g/dL or hematocrit greater than 30 is almost always not indicated.5 TRAN 02 is an outcome measure examining the number of patients who may have received more blood than necessary.  

Measure Time Period

90 minutes before the last intraoperative transfusion to 18 hours after Anesthesia End.


Adult patients requiring anesthesia who receive a transfusion.

  • Age <18 years
  • ASA 5 & 6 including Organ Procurement (CPT: 01990)
  • Cesarean Delivery Cases (determined by Obstetric Anesthesia Type value codes: 1, 2, 4, 7, 8) with an EBL > 1500cc or the HR>110, SBP<85, DBP<45, or O2Sat <95%
  • Massive Blood loss with EBL > 2000 mL
  • Massive Transfusion of 4 or more units of blood from 4 hours before Anesthesia Start to Anesthesia End
    • Note: for sites that document transfusions in mL instead of units: ASPIRE will default to 300mL/unit
  • Postpartum hemorrhage cases (ICD-10 code: 072.0, 072.1, 072.2, 072.3)
  • Procedures:
    • Burn cases (CPT codes 01951, 01952, 01953)
    • Cardiac Cases (determined by Procedure Type: Cardiac value codes >0)
    • Labor epidurals (determined by the Obstetric Anesthesia Type value codes: 3 & 6 including obstetric non-operative procedures – CPT: 01958)
Success Criteria
  • Hematocrit value documented as less than or equal to 30% and/or hemoglobin value documented as less than or equal 10 g/dL     OR
  • No hematocrit or hemoglobin checked within 18 hours of Anesthesia End.
Other Measure Details
  • All hemoglobin/hematocrit lab values drawn after the last transfusion and within 18 hours after anesthesia end will be evaluated. If the lowest of these values is ≤10g/dL or ≤30%, the case will pass.
  • If the hemoglobin or hematocrit at the time of the last transfusion (within 90 minutes before) is less than or equal to 8/24, the case will pass.
  • Transfusion is defined as:
    • Packed Red Blood Cells-Autologous, Homologous, Unknown Type
    • Whole Blood-Homologous, Unknown Type                          
    • Categorized Note- Blood Products
  • Hematocrit/hemoglobin are defined as:
    • POC - Blood gas-Hct measured,  Hemoglobin
    • POC – Hematocrit spun
    • POC – Coulter counter – Hematocrit, Hemoglobin
    • Formal lab – Hematocrit,  Hemoglobin
    • Formal lab - Blood gas - Hct measured, Hemoglobin
  • Hematocrit values < 1 reported in L/L (liters of blood cells per liter of blood volume) are multiplied by 100

*This measure will include only valid MPOG cases as defined by the Is Valid Case phenotype.
