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.
