From Good Laboratory Practice to Total Quality Management in Medical Laboratories : The Perspective October, 2002 S Cheng 1
What is Quality b Quality is the entity of a product ( service ) which fulfils the defined and expected requirement b The customer checks if the product meet the requirements 2
Quality in Medical Laboratory Testing b The right test result, at the b Right time, on the b Right specimen, from the right patient, with result interpretation based on b Correct reference data, and at the b Right price 3
Evolution of Quality Management Philosophy 1930 – 60, Q. C. ( Cure ) 1970 – 80, Q. A. ( Preventive ) To-day, TQM ( Holistic involvement ) 4
Evolution of Quality Systems 5
Overview on the Functions of The Medical Laboratory 6
Clinical Specimen Adulteration 7
Quality Management System b b Achieving customer satisfaction by meeting customer’s expectation and preventing non-conformity at all stage of process from design to service. Enhance the performance of the organization through internal and external audit 8
QM, QA and QC interrelationships 9
Why Quality Management is everybody’s darling b. Quality costs, but poor Quality costs more b Regulator : reduces workload, ( manpower ) b Blood Industry Officials: makes the environment transparent b Hospitals : reduces responsibility to patients 10
Cost of Quality 11
Demings chain Improvement of quality Improvement of productivity Market-share Price-reduction Secure position Cost-reduction Secure jobs 12
Demings chain in Laboratory Service Improvement of quality Improvement of productivity Market-share Price-reduction Secure position Cost-reduction Secure jobs 13
My problems with the definitions of quality b Does the customer have all the information he needs to qualify the products? Service? b Is it his responsibility to check the quality or standards? b Is’nt there a discrepancy between customer’s expectations and requirements ? 14
It is our ethical responsibility to define the level of quality b A patient is not able to figure all transfusion risks. He might be unconscious on intensive care. b We know all about transfusion risk and must be responsible for the safety. b A perfect balance is the major support for a good quality management. 15
Flawless quality management: ( Error Management ) b Quality management has to be flawless. Discovery of errors in documents, or problems must lead to the consideration to end, or change the process. 16
Quality Layers 1. 2. 3. 4. Minimal requirements “ Bad Quality” Functional Requirement “Quality” Non-functional requirements “Good Quality” Far ahead of customer expectations “Excellence” 17
Should’nt we achieve excellence ? Quality = Excellence begins in your mind 18
Quality Planning b Part of Quality management focused on setting quality objectives and specifying necessary processes and related resources to fulfil the quality objective 19
3 E in quality b Effectiveness ( doing the right things) - extent to which planed activities are realized and planed results achieved b Efficiency ( doing things right ) - relationship between the result achieved and the resources used b Excellence - Doing the right things right !! 20
The 8 columns of excellence Responsibility for the community Building partnerships Continuous learning Involvement of employees Orientation on results Orientation of customers Leadership & consequences of goals Management of processes & facts 21
Achieved By Good Practices b GLP – Good Laboratory Practice b GCL – Good Clinical Practice b GMP – Good Manufacturing Practice b GTP – Good Transportation Practice b GDP – Good Distribution Practice b GAMP – Good Automated Manufacturing Practice b GRP- Good Regulatory Practice 22
Medical laboratory quality system b A quality system is essential in the laboratory to ensure the correct results for the correct patient / donor b By Good Laboratory Practice ( GLP ) 23
Good Laboratory Practice( GLP ) b Main areas of GLP - Organization and personnel - Facilities - Equipment - Reagent / test kits - Documentation - Inter-laboratory comparison 24
Organization and Personnel b Quality management system On Accountability -Responsibilities -Authorities b Training - Competency based 25
Facilities b Appropriate infrastructure b Safety measures b Hygiene measures 26
Equipment b Validated - Does it do what you want it to do ? b Maintained b Calibrated 27
Reagents / Test Kits b Evaluated b Methodology validated b Test run validated - Kit / reagent controls - Internal control 28
Documentation (1) b Testing strategies / protocols - Specimen identification - Confidentiality b SOPs - Sample processing - Test performance and result interpretation - Inspection of incoming goods - Validation - Equipment maintenance and calibration - Safety 29
Documentation (2) b Records - Test results - Equipment maintenance - Equipment calibration - Control charts - Validation - Training 30
Inter-laboratory comparison b External Quality Assurance Scheme ( Proficiency Test , P. T. ) 31
By Other Quality Management System International Standards e. g. ISO 9000 series, ISO/IEC 17025: 1999 ( General Requirements for the Competence of Testing and Calibration Laboratories ) 32
ISO 1/IEC 17025, ISO 15189 Development History 33
In 1985 JCAHO published its 10 -step QA monitoring process. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Assign responsibility for QA plan. Define scope of patient care. Identify important aspects of care. Construct indicators. Define thresholds for evaluation. Collect and organize data. Evaluate data. Develop corrective action plan. Assess action; document improvement. Communicate relevant information. 34
JCAHO has also established nine dimensions of performance that must be included and measured in the design of the organization’s quality assessment and performance improvement plan: 35
Nine Dimension b Efficacy b Appropriateness b Availability b Timeliness b Effectiveness b Continuity b Safety b Efficiency b Care and Respect 36
National Accreditation Scheme b CAP Laboratory Accreditation Programm ( LAP ), USA b CPA , Clinical Pathology Accreditation ( UK) Ltd. , Standards for the Medical Laboratory 37
