Sample Handling01:02

Sample Handling

276
Transportation of samples from the collection point to the laboratory, as well as storage and preservation techniques, are crucial for maintaining sample integrity and ensuring accurate and reliable test results.
Samples should be transported carefully from collection points to the laboratory. They should be properly sealed and clearly labeled to prevent cross-contamination. To preserve the sample integrity, optimal temperature conditions during transport are essential. This could involve using...

Quality Assurance01:19

Quality Assurance

411
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

Quality Control01:05

Quality Control

598
Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

    Area of Science:

    • Clinical Laboratory Science
    • Quality Improvement in Healthcare
    • Patient Safety

    Background:

    • Clinical laboratories are crucial for patient diagnosis and management.
    • A significant percentage of blood samples (1.43%) were rejected, exceeding the target of 0.4%, primarily due to hemolysis.
    • Rejected samples pose risks to patient safety and clinical decision-making.

    Purpose of the Study:

    • To reduce the percentage of rejected blood samples by 50% in the emergency department and coronary intensive care unit.
    • To address preanalytical errors contributing to sample rejections.
    • To improve the overall quality of blood specimen collection and handling.

    Main Methods:

    • A multidisciplinary team implemented a quality improvement project targeting preanalytical errors.
    • Interventions included phlebotomy education, competency validation, use of appropriate consumables, and physician education.
    • Data were collected on rejected blood samples for chemistry, arterial blood gas, hematology, and coagulation tests.

    Main Results:

    • The percentage of rejected blood samples decreased from 1.43% (January 2015-April 2016) to 0.47% in 2018.
    • This reduction was statistically significant (p < 0.001).
    • The project successfully met its goal of reducing sample rejections.

    Conclusions:

    • A quality improvement approach effectively analyzed and addressed specimen rejection rates.
    • Weekly rapid cycle improvements accelerated goal achievement.
    • The implemented interventions significantly reduced blood sample rejections, improving laboratory quality and patient safety.
