Billing for red blood cell (RBC) transfusions is highly accurate in a large hospital. This study found excellent specificity and good sensitivity, validating administrative data for transfusion research.

Area of Science:

  • Health Services Research
  • Medical Informatics
  • Healthcare Administration

Background:

  • Administrative data are frequently used for research but often lack validated accuracy.
  • Assessing the accuracy of billing for blood transfusions is crucial for reliable data.

Purpose of the Study:

  • To evaluate the validity of billing for red blood cell (RBC) transfusions in a tertiary-care hospital.
  • To determine the accuracy of administrative data related to transfusion billing.

Main Methods:

  • A random sample of 358 patients billed for RBC transfusion and 358 not billed were selected from discharge data.
  • Blood bank transfusion records were cross-referenced with billing data to assess sensitivity and specificity.
  • Statistical tests (Wilcoxon's rank sum, chi-square) compared patient characteristics.

Main Results:

  • The sensitivity for billing RBC transfusions was 83% (95% CI, 79-87%), with 100% specificity.
  • No patients were billed without receiving a transfusion; 61 transfused patients were not billed.
  • Non-billed patients were older and less likely to have commercial insurance.

Conclusions:

  • Billing for RBC transfusions in this large institution is reassuringly valid.
  • The high specificity and sensitivity indicate reliable administrative data for transfusion research.
  • Findings suggest administrative data can be trusted for studies on blood transfusion practices.
