Q

Components of the quality framework

A
  1. Documents - policies, procedures, records - creation, retention, storage, disposal
  2. Personnel - induction, competency, authorisation, continuing education
  3. Facilities, safety - pre-analytical, testing, storage, staff facilities
  4. Equipment - selection, acceptance, use, maintenance, calibration, traceability
  5. Reagents and consumables - selection, acceptance, storage, records (lot, expiry)
  6. Service agreements - interactions with other entities
  7. Process requirements - testing, IQC, EQA
  8. Information - control and management
  9. Non-conformities and improvements

Q

Types of audit

A

Spot - made after events/incidents, or simply to ensure a process has occurred that should have
Examination/witness - confirm that actual procedure matches documented procedure (used by assessors)
Vertical - follows a sample through the entire testing system
Horizontal - done by accreditation bodies; assesses quality and competency of a department against ISO15189 criteria

Q

Define quality improvement

A

Practice of continuously assessing and adjusting performance using statistically and scientifically accepted procedures.

17
Q

What is “Lean” or “Lean Manufacturing”?

A

An efficiency-focussed method using empirical means to identify and eliminate wasteful production practices.

18
Q

2 types of analytical errors

A

Random
Systematic

19
Q

2 types of systematic errors

A

Constant
Proportional

20
Q

Top 5 causes of preanalytical errors

A

Speci collection tube not filled properly
Patient ID error
Inappropriate speci collection tube/container
Test request error
Empty collection tube

21
Q

What is the difference between 2-point and 1-point calibration?

A

In 2-point calibration, 2 known values are used to construct a linear calibration curve. In 1-point calibration, a single level is used to determine the position of the line - the slope of the line is maintained from the previous 2-point calibration.

22
Q

Approaches to QC

A
  1. Westgaard rules
  2. Moving averages
  3. Patient based real time QC
23
Q

What is patient-based real time QC?

A

Activities that use real patient data to detect analytical errors
- population data eg means or medians of a single analyte
- individual data eg within patient changes such as the delta check
