Content Overview
• The approach we take to achieve quality
• Essential elements of a lab quality system
• Quality assurance procedures in the medical laboratory testing site
• How the laboratory documents its program of quality for all phases of testing - before, during and after testing
What is “Quality?”
• The ability of a product or service to satisfy stated or implied needs of a specific customer
• In the lab: accuracy, precision and timeliness
• Achieved by conforming to established requirements and standards
Discussion – Dining Out: A Quality Experience
• Think about your expectations for quality
• What might you expect for a quality experience at a restaurant?
Why Quality?

Quality in All Aspects
of Health Care
A Systems Approach to Quality
• Considers all components within a system– Such as organs working
together as a system in
the body
• To produce quality service in the laboratory, all facets are needed to work together
A System...
• Identifies the connection and relationship (e.g., cause and effect) among the components
• Example of cause and effect: Anemia may be caused by many reasons including lack of iron; but lack of energy and fatigue is often the effect
Definition of a Lab Quality System
• A system with an organizational structure of management and staff who carry out their responsibilities using good laboratory practices and procedures including the resources necessary for providing quality laboratory test results.
• In other words…all activities which contribute to quality tests, directly or indirectly.
Benefits of a Quality System
• Patient benefits with accurate results for the clinician to diagnose, treat and monitor their health
• Proactively detects and reduces errors before results are released
• Improves consistency of results between testing sites and increases clinician confidence
• Ultimately is the most cost effective
Interactive Opportunity
• What does a Quality System mean for the laboratory?
• How is a quality laboratory established?
Lab Quality Systems:The 12 Quality Essentials

Activity
Break into four groups and define the specificlaboratory needs that each of the
Quality Essentials include.
Secondly, relate the Quality Essentials toThe ISO 15189 Checklist Sections. Are they
essentially the same?

ISO 15189 Aligns with WHO Checklist Sections
ISO 15189:2012
• Based upon ISO/IEC 17025 and ISO 9001, specifies requirements for competence and quality particular to medical laboratories
• A country could have its own specific regulations or requirements applicable to its professional personnel, their activities, & responsibilities
• Medical laboratory services are essential to patient care and must meet the needs of all patients and the clinical personnel responsible for the care of those patients.
ISO 15189:2012
Such services include:• Arrangements for examination requests, patient
preparation, patient identification, collection of samples, transportation, storage, processing and examination of clinical samples, with interpretation, reporting and advice, in addition to the considerations of safety and ethics in medical laboratory work

Policies verses ProceduresPolicies Procedures
Definition Policies are statements of WHAT the laboratory will do
Procedures are SOPs on HOW policies are implemented
Examples • The laboratory will maintain an orderly system for all documents and records so that all documents and records can easily be located, are current and available to staff, and are retained or disposed of according to law.
SOP for Document Control:• All procedures are
numbered• A master index is
maintained• All SOPs are reviewed
annually• Records are retained
for X years, etc……..
Writing YOUR Quality Manual
1. Begin with a Quality Statement or Objective for YOUR laboratory to have a commitment to a culture of Quality
2. Outline YOUR Scope of Service
3. Outline the roles and responsibilities of YOUR management and staff
4. Outline the organization of the Manual i.e. how the manual is arranged by addressing Quality Essentials.
*See ISO 15189: 4.2.3/4.2.4
Examples
Management Review:“It shall be the policy of xxxxxx Laboratory to establish an annual workplan and budget in coordination with and approval of upper management. This plan will be communicated to all laboratory staff.” (See File: Lab Workplan and Budget - Lab Manager Office)
“ At least annually, the laboratory manager will review with upper management (summary of items listed in ISO 15189:2012 (Meeting minutes) “
Management Review (cont)“There shall be an annual review of Laboratory Quality Improvement to ensure that data in the form of Quality Indicators are collected and Improvement Projects are identified and undertaken.”
“The Laboratory Manager or supervisor shall review monthly (or quarterly if more appropriate), the following quality and technical records: (see ISO 15189:2012 as it applies to your lab)”
Examples
Facilities and Safety“XXXXX Laboratory will provide, with the approval and oversight of upper management, a safe environment for its clients and staff. This includes the physical structure, the necessary safety equipment and supplies for specimen handling and testing, defined procedures for waste disposal, prophylaxis for staff upon specific exposure and training for all safety procedures.Reference: See Safety Manual Document #XXXX located in the LM office and all lab sections”
Another Example
• Divide in groups and with the Quality Essential you previously worked with, begin a plan on how to incorporate this essential into YOUR Quality Manual.
• Note: You should use the ISO 15189:2012 Checklist as your guide n
Activity and Homework
• Laboratory management and supervisory staff establish quality assurance policies procedures
• Test site personnel implement the quality assurance procedures
Who Is Responsible for Quality?
EVERYONE!
Why is the Quality System Important to Patient Sample
Testing? • Ensures that quality is the foundation of
everything we do
• Sets the standard for level of quality
• Meets/exceeds customer expectations
• Provides means to prevent, detect and correct problems
Why is the Quality System Important to Patient Sample
Testing? • Becomes the core of a monitoring, evaluation,
and improvement system
• Reduces costs
Even the simplest Rapid Test is not foolproof
