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
