I don't believe the AABB has a sample size requirement. It would depend on your facility's population and its acuity. Some hospitals that I've worked for choose 4 random transfusions per month.

We do 10 per month for our largest facility and 2-4 per month for the smaller hospitals.

When doing a documentation audit for blood administration, you might also consider the Joint Commission guidelines in determining how many to look at...the term "cases" below, could be applied to number of patients transfused or number of products transfused.

My hospital QA department gave me the following TJC guideline for audits:

The TJC recommendations state:

• For a population size of fewer than 30 cases, sample 100% of available cases

  
  

• For a population size of 30-100 cases, sample 30 cases

  
  

• For a population size of 101-500 cases, sample 50 cases

  
  

• For a population size of greater than 500 cases, sample 70 cases

  
  

• This is taken directly out of the HAS( Hospital Accreditation Standards manual) page 11 under sample size.
