Q

What are the 15 considerations to be taken into account when deciding on whether to introduce a new test into the laboratory?

A
  1. Is there a clinical need for the test? - # of samples, disease incidence etc.
  2. Is there a clinical demand for the test? - who will order the test, where would referrals come from?
  3. Does the test have clinical utility? - would results affect treatment or health outcome, low penetrance, environmental effect?
  4. Is the test ethical/legal?
  5. Technical testing strategy - what type of test? what sample type? mutation types? Accuracy, reliability, sensitivity/specificity etc. Screen or diagnostic?
  6. Impact on current working practices - potential workload, staffing, set-up time
  7. Will the new test replace an existing test? - improve TAT? improve DxYx, how much DNA/cells needed? controls needed? externally or internally validated test? confirmation of results?
  8. Budget considerations - staffing, consumables, equipment, competitive pricing, need a business case? NCG funded test?
  9. Implications for staffing and training requirements
  10. Equipment/lab set-up - which techniques are best, new or existing equipment?
  11. Population factors
  12. Background work - disease information etc
  13. Validation work - including SOP writing, audits, enrol in EQA scheme
  14. Implement service - training other staff, ongoing improvements, authorise SOP, worksheets and information management, report templates, advertise service, gene dossier?
  15. Request user feedback once test established - user surveys

Q

List some components of clinical governance

A 
Clinical audit
Clinical effectiveness
Education and training
Risk management
Openness
R&D
Clinical information and IT
Patient and public involvement
Staffing
17
Q

What are the three key attributes of clinical governance?

A
  1. recognisably high standards of care
  2. Accountability and responsibility for those standards of care
  3. Constant improvement
18
Q

Define clinical governance

A

Clinical governance is a system through which NHS organisations are responsible and accountable improving quality of their services and safeguarding high standards of care.

19
Q

Outline the Continuous Improvement Cycle

A

Plan (determine user requirements and plan how these will be met)
Do (acquire resources to meet requirements, document procedures, provide traiinng, implement working procedure)
Check (audit to ensure activities are carried out correctly)
Act (correct and prevent when things go wrong)

20
Q

What are CAPA?

A

Corrective and Preventative actions.
Corrective actions eliminate the cause of the non-conformity
Preventative actions stop a potential non-conformity

21
Q

How does a QMS stop errors occurring?

A

Ensures all aspects of a process are considered
Documents procedures to ensure standards are met
Encourages review of techniques to ensure up-to-date methods are used
Controls SOP changes
Provides platform for continuous improvement

22
Q

Give examples of QMS documentation

A 
Quality Manual
Policies
Calibration certificates
COSHH forms
SOPs
H&S records
Meeting minutes
Job descriptions and staff records
Staff training records and CPD
Appraisal records
Maintenance records
Batch records
Incident forms
Audit records
Verification/Validation records
Test results/reports
23
Q

What are the 9 components of the QMS?

A 
Quality manual
QMS documentation
Quality Assurance - getting it right first time
Internal QC
Quality Improvement
Continual Improvement cycle
Quality Assessment
Audit
Accreditation
24
Q

What is a Quality Management System?

A

A defined set of procedures, structures, regulations and responsibilities that ensure the organisation is capable of delivering required standard of services

25
Q

What should be contained within an audit record?

A 
Name of staff member performing the audit
Date performed
Reference number
The scope of the audit
Any non-conformaties
Any CAPAs
Date and signature on completion
26
Q

Describe the 4 classes of audit and give an example of each

A

Clinical audits - they form part of clinical governance, they are required to provide evidence of current practice against national guidelines and monitor patient outcomes. They can be prospective or retrospective. e.g. referral patterns or TATs

Vertical audits - allow audit of an entire workflow/process. Used in labs to follow one sample from receipt to report - record everything (temperature of fridges, lot numbers, staff training records etc.)

Horizontal audits - examine one part of the process in detail. Can be used to determine if all batch records are held in the right place.

Examination audits - Witness to see if a SOP is being correctly followed, or staff members are appropriately trained.

27
Q

Name the 4 classes of Audit.

A
  1. Clinical audit
  2. Horizontal Audit
  3. Vertical Audit
  4. Examination audit
28
Q

What are the purposes of audit?

A 
To demonstrate quality of service
Identify areas for change
Continued improvement
Assist in implementation of guidelines and services
Monitor consistency of performance
Measure performance against benchmark
29
Q

What are the 5 stages of the audit cycle?

A 
Set standards
Measure current practice
Compare practice vs standards
Reflect, plan, implement change
Re-audit
30
Q

What is the definition of “Audit”

A

A systematic, documented and independent process to obtain evidence and objectively evaluate the extent to which a set of criteria are fulfilled.

31
Q

How can stratified medicine be defined?

A

Various definitions:

The grouping of patients based on risk of disease or response to therapy by using diagnostic tests or techniques.

The tailoring of medical treatment to the individual characteristics of each patient [through assigning patients to certain subpopulations].

[Within genetics}: The use of genetic or other biomarker information to improve the safety, effectiveness and health outcomes of patients via more efficiently targeted risk stratification, prevention and tailored medication and treatment management approaches.

An emerging approach for disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle for each person.

32
Q

What are the main benefits of personalised medicine within genomic testing?

A

Better/more accurate diagnosis (molecular sub typing of disease) e.g. in CNS tumours

Optimal treatment selection e.g. response to TKIs / immunotherapy

Improved/more accurate prognostication e.g. high/low risk profiles in acute leukaemias

Avoidance of drug toxicities (e.g. DPYD/TPMT testing)

More cost effective healthcare (improved response rates by not giving patients expensive drugs that are unlikely to work)

33
Q

What are the four ‘P’s of precision medicine?

A

Precision medicine involves the ‘Four Ps’:

  1. Prediction and prevention of disease
  2. Precise diagnosis
  3. Personalised interventions
  4. Participatory role for patients
34
Q

What is personalised medicine?

A

Selection of the best approach to manage a specific patient, based on available biological information about the patient as well as a patient’s personal preferences, environmental factors, social factors and other factors that may affect the treatment choice.

35
Q

What is precision medicine?

A

A disease treatment or prevention that takes into account some individual variability. An example may be the decision to proceed with allogeneic stem cell transplant in the context of AML patients in complete morphological remission: clinicians have to consider not just the prognostic risk associated with the genetic profile of the AML clone, but also patient’s age, co-morbidities, MRD, personal preferences.

36
Q

What are the main advantages to the integration of molecular pathology services?

A
  • Higher volumes of testing mean lower costs per test
  • Expertise is concentrated, resulting in higher-quality testing
  • All molecular tests are available to all patients in each region in a single location, simplifying logistics
37
Q

What are the main challenges to integration of molecular pathology services?

A

• Turnaround times deteriorate severely, both from transporting tissue/reports and in cases being queued for testing in large laboratories.
