  QT4 - In-Date Blood Product Wastage


Updated December 15, 2008

In-Date Blood Product Wastage QT4
Blood for transfusion is a precious resource. At a minimum, wastage of unexpired blood represents a financial loss to the health care system. More ominously, systemic wastage of blood may reflect a care environment that is out of control and may pose risks to patient safety.

Monitor Objective
Compare the rates of blood product wastage (i.e., units discarded in-date) in participating hospitals and track rates of improvement over time.

Data Collection
On a monthly basis, participants will use blood bank records to obtain information on the total number of units transfused for each type of blood component. Participants will track the number and type of blood units that are wasted in-date and the circumstances of wastage. The following types of blood components will be included: whole blood (allogeneic); red blood cells (allogeneic); frozen plasma; platelet concentrates; single donor platelets; and cryoprecipitate.

Performance Indicators

  • Overall Wastage Rate (%)
  • Other Blood Components Wastage Rates (%)
  • Breakdown of Wastage Reasons (%)

Input forms for quarterly data will be sent to participants approximately three weeks prior to the quarter.
