Descriptive Information
Brief Title  ICMJE Small-Volume Tubes to Reduce Anemia and Transfusion
Official Title  ICMJE Small-Volume Tubes to Reduce Anemia and Transfusion: A Pragmatic Stepped Wedge Cluster Randomized Trial
Brief Summary STRATUS will evaluate the use of small-volume ("soft-draw") blood collection tubes for laboratory testing in reducing anemia and transfusion in intensive care unit patients without significant adverse consequences. This is a simple, cost-neutral intervention that could improve the quality of patient care and reduce the harms of frequent laboratory testing.
Detailed Description

Blood sampling can cause significant unnecessary blood loss particularly in the intensive care unit (ICU). Blood loss contributes to anemia which is highly prevalent in the ICU and is associated with major adverse cardiovascular outcomes and death. Red blood cell (RBC) transfusions to correct anemia also have significant health risks.

Using a stepped wedge cluster randomized trial design, the specific aim of the STRATUS study is to evaluate whether the routine use of small-volume blood collection tubes reduces RBC transfusion compared to standard-volume blood collection tubes in adult ICU patients.

Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: Randomized
Intervention Model: Crossover Assignment
Intervention Model Description:
A stepped wedge cluster randomized trial in which ICUs (clusters) switch from a strategy of blood collection using standard-draw tubes (control) to soft-draw tubes (intervention). In this design, the timing at which individual ICUs switch to the intervention is randomly assigned.
Masking: None (Open Label)
Primary Purpose: Prevention
Condition  ICMJE Blood Loss Anemia
Intervention  ICMJE
  • Device: Small-Volume Blood Collection Tubes
    Small-volume vacuum (< 4 mL) ethylenediaminetetraacetic acid (EDTA), lithium-heparin, citrate, fluoride and serum blood collection tubes.
  • Device: Standard-Volume Blood Collection Tubes
    Standard-volume (≥ 4 mL) ethylenediaminetetraacetic acid (EDTA), lithium-heparin, citrate, fluoride and serum blood collection tubes.
Study Arms  ICMJE
  • Active Comparator: Control Period

    Intervention: Device: Standard-Volume Blood Collection Tubes
  • Experimental: Intervention Period
    Small-Volume Blood Collection Tubes ("soft-draw")
