Data Element
Version 2010B

Data Element Name: Transfusion Start Date
Collected For: BM-05,
Definition:The date that the blood transfusion unit (bag) was administered.
Suggested Data Collection Question:What is the date that the blood transfusion unit (bag) was administered?
Length:10 – MM-DD-YYYY (includes dashes)
Occurs:1 - 27
Allowable Values:


MM = Month (01-12)
DD = Day (01-31)
YYYY = Year (2001-Current Year)
Leave Blank if Unable to Determine

Notes for Abstraction:
  • Abstract the Transfusion Date associated with the Transfusion Start Time of the unit (bag) or dose from the blood product event ID selected for abstraction.
  • Some of the dates of the transfusion events will be the same date. Record a transfusion date for each unit abstracted up to three units per event per blood product (RBCs, plasma, platelets).
  • The medical record must be abstracted as documented (taken at “face value”). When the date documented is obviously in error (not a valid date/format) and no other documentation is found that provides this information, the abstractor should leave blank.
  • Example: Documentation indicates the Transfusion Start Date was 03-42-2008. No other documentation in the medical record provides a valid date. Since the Transfusion Start Date is outside of the range listed in the Allowable Values for “Day,” it is not a valid date and the abstractor should leave blank.
Suggested Data Sources:
  • Anesthesia record
  • Emergency department record
  • Nursing notes
  • Progress notes
  • Operative notes
