Study Notes
Clinical Chemistry I (0202304) - Week 08: Quality Management
- Course Instructor: Mohammad QABAJAH
- Course Email: [email protected]
- Week: 8
- Topic: Quality Management
Objectives
- Describe the quality control system and methods for validating laboratory results.
- Describe the laboratory testing processes and potential errors during each process.
- Understand pre-analytical, analytical, and post-analytical variables and their impact on lab test results.
- Identify how pre-analytical, analytical, and post-analytical variables are controlled.
Total Quality Management
- Total quality management (TQM) of the clinical laboratory involves:
- Controlling pre-analytical variables
- Controlling analytical variables
- External quality assessment and proficiency testing programs
- Early detection of problems is crucial for preventing consequences.
Implementing TQM
- Quality Planning (PDCA): Plan-Do-Check-Act cycle for quality improvement.
- Quality Laboratory Processes (QLP): Analytical processes, policies, practices, and procedures of work.
- Quality Control (QC): Statistical and non-statistical procedures like linearity checks, reagent/standard checks, and temperature monitoring.
- Quality Assessment (QA): Turnaround time (TAT), specimen and patient identification, and test utility.
Control of Pre-analytical Variables
-
Patient Identification:
- Correct identification of patients and specimens is essential.
- Using at least 2 identifiers.
-
Turnaround Time (TAT):
- Time taken for specimen analysis.
- Time taken for reporting test results.
- Define TAT for each lab test for monitoring.
- Procedures for specimen collection, receipt, and reporting.
-
Laboratory Log - Specimen + Request:
- Log format:
- Patient name
- Patient identification number
- Matching specimen
- Adequate specimen volume
- Tests requested
- Rejection reasons
- Electronic logging on lab records to avoid transcription errors, especially with manual data entry.
- Log format:
-
Patient Preparation:
- Patient factors affecting test results:
- Recent intake of food, alcohol, or drugs
- Smoking
- Exercise
- Stress
- Sleep
- Define instructions for patient preparation and specimen acquisition.
- Patient factors affecting test results:
-
Specimen Collection:
- Procedures for ensuring proper specimen collection, including preservatives, containers.
-
Specimen Separation and Distribution:
- Use of centrifuges and containers.
-
Specimen Transport:
- Cooling, freezing, and protecting from light during transport.
Non-controllable Variables
-
Biological Influences:
- Age (newborn, child, adult, elderly)
- Sex
-
Environmental Factors:
- Altitude
- Ambient temperature
- Geographic location
- Seasonal influence
-
Underlying Medical Conditions:
- Obesity
- Blindness
- Pregnancy
- Fever
- Shock and trauma
