    Study Notes

    Quality Control and Quality Assurance

    • Quality Control (QC): The use of checks and controls to assure quality.
    • Quality Assurance (QA): A program or process designed to prevent problems in the future by evaluating present and past performance.

    Total Quality Management (TQM)

    • A comprehensive system for achieving continuous improvement in customer satisfaction.
    • Based on 4 principles:
      • Customer satisfaction
      • Everyone is involved (management and employees)
      • Constant improvement
      • Procedure-oriented

    Quality Assurance Cycle (PDCA Cycle or Deming Cycle)

    • Phases:
      • Plan: Establish process-related objectives and determine processes required to deliver a high-quality end product.
      • Do: Development and testing of processes, and make changes to processes.
      • Check: Monitor processes, modify them, and check if they meet predetermined objectives.
      • Act: Implement actions to achieve improvements in processes.

    Quality Control Procedures

    • Calibration: The process of ensuring that instruments are accurate and reliable.
    • Standardization: The process of ensuring that equipment and materials are consistent and reliable.
    • Proficiency testing: A program to evaluate the performance of laboratories.

    Delta Check

    • A quality control procedure that involves comparing current lab results with previous results for the same test on the same patient.

    Quality Indicators

    • Measurement of quality control indicators to evaluate laboratory performance.
    • Threshold values are established for each indicator.

    Documentation

    • Recording QC measures is an important part of the quality assurance program.
    • Documentation is essential to ensure traceability, accountability, and compliance with regulatory requirements.

    Levey-Jennings Chart

    • A graph that quality control data is plotted on to give a visual indication of whether a laboratory test is working well.

    Westgard Rules

    • A set of rules used for laboratory quality control to ensure that quality control data is within acceptable limits.

    Standards

    • Definition: A known value or reference point used to establish a benchmark for measurement.
    • Types:
      • Chemically pure standards
      • Serum-based standards

    Controls

    • Definition: Materials with known characteristics used to evaluate laboratory tests.
    • Types:
      • Positive controls
      • Negative controls
      • Calibrators

    Quality Management in Laboratory Environments: The 12 Essentials

      1. Organization: A formal quality management system that supports consistent procedures.
      1. Personnel: Capable staff members are the single most important asset to a laboratory.
      1. Equipment: Every piece of equipment used in the laboratory must be maintained to operate safely.
      1. Purchasing and Inventory: Properly managing the supply chain is critical to ensure that raw inputs and other supplies are consistently high-quality.
      1. Process Control: QC processes for testing, including collection, handling, method verification, and process validation.
      1. Information Management: Managing laboratory information, including QC test results, maintenance reports, and other data.
      1. Documents and Records: Documents are a similar concept to information management, and there’s a significant overlap between these categories.
      1. Occurrence Management: An “occurrence” is any error or non-conformance.
      1. Assessment: Comparing laboratory performance to internal standards for quality or external data sets.
      1. Process Improvement: Continuous process improvement of laboratory processes.
      1. Customer Service: Supporting operations that consistently provide a positive customer experience through the production of consistently high-quality products or other missions.
      1. Facilities and Safety: A comprehensive set of procedures and standards to ensure a safe, secure, and clean environment.

    Reflective Practice

    • Allows individuals to recognize their strengths and weaknesses and use this to guide on-going learning.
    • Development of metacognitive abilities, such as analyzing thoughts.
    • Improved understanding of the connections between theory and practice.

    Individual Quality Control Plan

    • A risk-based objective approach to QC tailored to each laboratory.

    Risk Management

    • Definition: The identification, classification, and prioritization of risks.
    • Basic steps in risk management:
      • Identification of the risk
      • Treatment of the risk (using policies and procedures)
      • Education of employees and patients
      • Evaluation of what was done and to improve on it
