Study Notes

Continual Improvement Concept

Process improvement is one of the 12 quality system essentials (QSE) aimed at ensuring ongoing enhancement of laboratory quality.
Edwards Deming, a pioneer in quality management, advocated for continual improvement, focusing on reliable and quality laboratory results.
Deming’s 14 points for quality, applicable to laboratory settings, emphasize:
- Creating constancy of purpose for improvement.
- Constantly and forever improving processes, highlighting that perfection is an ongoing pursuit.

Deming’s PDCA Cycle

The PDCA Cycle (Plan-Do-Check-Act) serves as a framework for achieving continual improvement:
- Plan: Identify problems and sources of error; develop a plan for improvement based on gathered data.
- Do: Implement the improvement plan.
- Check: Monitor effectiveness, possibly through pilot studies, and assess outcomes using audits and focused reviews.
- Act: Take corrective action based on assessments and begin the cycle anew, ensuring continual refinement of laboratory processes.

ISO 15189 and Continual Improvement

ISO 15189 outlines similar activities for continual laboratory improvement:
- Identifying system weaknesses.
- Developing and implementing improvement plans.
- Reviewing effectiveness through audits and focused reviews.
- Adjusting actions based on review results to enhance the system.

Tools for Process Improvement

Process improvement is a systematic approach to enhance laboratory quality by addressing inputs and outputs in workflows.
Audits (internal and external) uncover weaknesses and problem areas in laboratory processes.
Participation in External Quality Assessment (EQA) helps compare laboratory performance against peers.
Regular management reviews of quality control, inventory, and equipment maintenance records provide insights for improvement.
Monitoring customer complaints and errors help identify Opportunities for Improvement (OFI), guiding corrective actions.
Establishing quality indicators is essential for setting performance goals and directing improvement efforts.

New Tools for Improvement

Innovations from the manufacturing industry are being adapted for laboratory quality improvement:
- Lean: Focuses on optimizing space, time, and workflow efficiency, aiming to save resources and minimize errors in laboratory processes.
- Six Sigma: A structured approach for project planning and error reduction, with core processes: define, measure, analyze, improve, and control (DMAIC), driving systematic improvements.
