Summary
Bedside blood transfusion errors are common and often unreported, with major errors occurring in 0.5% of patients. This study highlights the need for improved error detection and reporting to enhance patient safety during transfusions.
Area of Science:
- Transfusion Medicine
- Patient Safety
- Healthcare Quality Improvement
Background:
- Existing data underestimates the true incidence of bedside blood transfusion errors.
- Published figures often rely on clinically significant events or indirect assessment methods.
- Errors occurring after blood products leave the blood bank are a significant concern.
Purpose of the Study:
- To prospectively assess blood transfusion practices and identify error-prone steps.
- To quantify the incidence of major and recording errors during bedside transfusions.
- To evaluate the effectiveness of a 'descending' inquiry method for error detection.
Main Methods:
- Prospective, randomized study (SAnGUIS project) involving 808 patients undergoing elective surgery.
- Tracing of 3,485 transfused blood units over 15 months.
- Classification of errors into major (wrong unit transfusion) and recording errors (misrecording, mislabelling, documentation failure).
Main Results:
- 165 bedside transfusion errors were identified.
- Major errors occurred in 4 patients (0.5%), including 7 misidentifications (0.2% of units).
- 150 recording errors involved misrecordings, mislabellings, and documentation failures.
Conclusions:
- Most bedside transfusion errors go unnoticed and unreported, indicating a significant underestimation of their incidence.
- Measurement of error rates is crucial for quality improvement in transfusion practices.
- Feedback to staff can motivate measures to reduce bedside transfusion errors and improve patient safety.
