Area of Science:

Transfusion Medicine
Laboratory Science
Patient Safety

Background:

Accurate specimen identification and labeling are crucial preanalytic steps in transfusion compatibility testing.
Specimen mislabeling poses a significant risk to patient safety and laboratory workflow.

Purpose of the Study:

To establish baseline data on specimen mislabeling, focusing on major errors.
To develop and implement a corrective action plan to reduce mislabeling incidents.

Main Methods:

Recorded and categorized all mislabeled specimens for type and screen tests.
Tracked major mislabeling events by their origin, providing weekly feedback to high-incidence areas.
Analyzed data over 21 months in a university hospital setting.

Main Results:

The overall mislabeling rate was 0.5% (243/49,955 specimens).
Major mislabeling events constituted 47% of all mislabels.
Following weekly feedback, the emergency department's contribution to major mislabeling decreased from 47% to 14%.

Conclusions:

Collecting and trending data on mislabeled samples is effective in identifying problem areas.
Timely feedback to patient care areas can drive practice changes and reduce specimen mislabeling.
This intervention improved phlebotomy practices and enhanced patient safety in transfusion services.
