Quality Control Circle Practices to Reduce Specimen Rejection Rates.

Area of Science:

• Medical Laboratory Science
• Healthcare Quality Improvement
• Clinical Diagnostics

Background:

• The pre-analytical phase of laboratory testing is a major source of errors (approx. 70%), impacting patient care.
• High specimen rejection rates lead to diagnostic delays, increased costs, and patient discomfort.
• Quality Control Circles (QCC) are utilized in healthcare to enhance process efficiency and minimize errors.

Purpose of the Study:

• To assess the effectiveness of Quality Control Circles (QCC) in reducing specimen rejection rates within a hospital clinical laboratory.
• To identify key factors contributing to specimen rejection and implement targeted interventions.

Main Methods:

• A Quality Control Circle (QCC) initiative was implemented from July 2021 to August 2022.
• The initiative utilized the Plan-Do-Check-Act (PDCA) cycle and quality control tools like flowchart, Pareto, and Fishbone analyses.
• Specimen rejection rates were statistically analyzed pre- and post-intervention.

Main Results:

• A significant reduction in monthly specimen rejection rates was observed, decreasing from 1.13% to 0.27%.
• Key rejection factors identified were insufficient sample collection information and blood clotting.
• Targeted interventions, including liaisons, a quality control team, and enhanced training, were implemented.

Conclusions:

• Quality Control Circle (QCC) practices effectively decreased specimen rejection rates in the clinical laboratory setting.
• Systematic quality control and targeted interventions are crucial for optimizing laboratory processes.
• The QCC model shows promise for improving quality and efficiency in broader healthcare applications.
