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

Description

The purpose of this study is to evaluate the effectiveness of small phlebotomy tubes to reduce RBC transfusions in medical intensive care unit (ICU) and Intermediate care unit (IMU) patients with low hemoglobin compared with standard size tubes, to compare the intervention and the control groups in regards to: ICU length of stay (LOS), ICU mortality, hospital LOS, and hospital mortality and to assess the acceptability of small phlebotomy tubes in adult ICU and IMU patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Admission to the medical ICU or IMU.
  • * Hemoglobin less than 10 g/dL.
  • * Clinical bleeding. Defined as any bleeding needing an intervention. An intervention could be an increase in the frequency of hemoglobin monitoring, a transfusion, a procedure, or a consultation intended to prevent or treat bleeding.
  • * Hemolytic disorder (e.g. sickle cell disease, hereditary spherocytosis, autoimmune hemolytic anemia).
  • * Bone marrow disorder (e.g. aplastic anemia, leukemia, marrow infiltration disorder, chemotherapy within the last 8 weeks).
  • * Jehovah's Witnesses.
  • * Patient is comfort care measures only.
  • * Refractory shock: Mean arterial blood pressure below 65 mmHg despite maximal doses of 3 vasopressors. Maximal dose of vasopressors are as follows: Norepinephrine 70 mcg/min; vasopressin 0.03 units/min; epinephrine 35 mcg/min; dopamine 20 mcg/kg/min; phenylephrine 350 mcg/min.
  • * Severe acidosis: pH below 7 in more than one arterial blood gas in the past 24 hours, in the absence of diabetic ketoacidosis.
  • * Surgical admission diagnosis.
  • * Pregnancy.
  • * Current prisoner
