Effectiveness of Small Phlebotomy Tubes in Reducing Blood Transfusions in Adult Medical Intensive Care Unit and Intermediate Care Unit Patients With Anemia

"In the small tubes group, the recommended blood volumes are 0.5 mL for hematology and single chemistry tests, and 1 mL when multiple chemistry tests are needed. A, a non-formulary medication order will be placed in the electronic medical record to alert nurses to collect blood in small tubes. Participants will continue to use small tubes anytime they are in the ICU or IMU."

In the standard tubes group, the recommended blood volumes are 4.0 mL for hematology and 3.0 for chemistry tests.
