The STRATUS Pilot study evaluated 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 was a simple, cost-neutral intervention that could improve the quality of patient care and reduce the harms of frequent laboratory testing.

The STRATUS Pilot Study is a prospective observational study (before-after design) to assess the feasibility of implementing a full-scale randomized trial powered for clinical outcomes:

  • RBC transfusion
  • Incidence and severity of anemia.

Identification of barriers and facilitators of implementation will enhance the conduct of the full-scale trial and facilitate incorporation of the intervention into routine practice.
