Nurses frequently misinterpret pretransfusion bedside compatibility tests (PBCTs), leading to ABO incompatibility risks. Improving PBCT interpretation is crucial for patient safety in blood transfusions.

Area of Science:

  • Transfusion Medicine
  • Patient Safety
  • Clinical Pathology

Background:

  • Analysis of ABO incompatibility incidents reveals poor interpretation of pretransfusion bedside compatibility tests (PBCTs) as a primary issue.
  • Nurses' understanding of donor and recipient blood groups during PBCTs was investigated as a source of error.

Purpose of the Study:

  • To identify and analyze sources of error in nurses' interpretation of pretransfusion bedside compatibility tests (PBCTs).
  • To assess the impact of nurse experience and interpretative aids on PBCT accuracy.

Main Methods:

  • 48 nurses from four transfusion sectors were randomly selected based on seniority.
  • Nurses interpreted 24 photos of PBCTs, some with irregularities, with half receiving a diagram to aid interpretation.

Main Results:

  • An overall error rate of 39.8% was observed in PBCT interpretation.
  • Errors were lower for interpretable compatible (7.3%) or incompatible (6.3%) tests.
  • Use of a diagram reduced errors in interpretable tests to 22.2%.

Conclusions:

  • Pretransfusion bedside compatibility tests (PBCTs) are not a sufficiently reliable safety procedure.
  • Development of more effective methods is necessary to minimize the risk of blood transfusion incompatibility accidents.
