Quality Issues
Cervical Sample Taker Training

Quality Assurance
The NHSCSP is one of the best quality assured screening programmes
QA guidelines cover all aspects of the programme

Limitations of Cervical Screening
No screening test can provide 100% protection
Non-attendance Sampling error Screening error Interval cancers

Samples
Ensure correct patient/details Good quality sample (Good
technique & Audit) Result must be back to patient
within 2 weeks

How to measure sample quality?
Monitor inadequate samples
Monitor whether samples contain evidence of transformation zone sampling
![Page 6: Quality Issues Cervical Sample Taker Training. Quality Assurance The NHSCSP is one of the best quality assured screening programmes QA guidelines cover.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649cc45503460f9498deba/html5/thumbnails/6.jpg)
Possible reasons for inadequate samples
Excess Blood Menstrual samples Large ectropion Excess mucus Atrophic cervix Lubricant Poor sampling technique/sample transfer
Should all be covered during practical session

Auditing the quality of your samples
![Page 8: Quality Issues Cervical Sample Taker Training. Quality Assurance The NHSCSP is one of the best quality assured screening programmes QA guidelines cover.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649cc45503460f9498deba/html5/thumbnails/8.jpg)
Transformation Zone Sampling
It is important that the TZ is sampled as this is the area where abnormalities may arise
![Page 9: Quality Issues Cervical Sample Taker Training. Quality Assurance The NHSCSP is one of the best quality assured screening programmes QA guidelines cover.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649cc45503460f9498deba/html5/thumbnails/9.jpg)
Transformation Zone Sampling
A sample does not have to have TZ material to be called negative
Why do some samples not contain TZ material? Position of TZ in post-menopausal
women Poor sampling?
![Page 10: Quality Issues Cervical Sample Taker Training. Quality Assurance The NHSCSP is one of the best quality assured screening programmes QA guidelines cover.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649cc45503460f9498deba/html5/thumbnails/10.jpg)
Transformation zone sampling Audit of TZ gives an indication of the
quality of your sample taking
In women aged 25-50, 80% of samples should contain evidence of TZ sampling
This is your target during training period
Must see reports of all samples taken
![Page 11: Quality Issues Cervical Sample Taker Training. Quality Assurance The NHSCSP is one of the best quality assured screening programmes QA guidelines cover.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649cc45503460f9498deba/html5/thumbnails/11.jpg)
Auditing Quality Sample Taker 1 : Inadequate rate 0% Sample Taker 2: Inadequate rate 2% Who would you rather took your sample? Sample Taker 1: TZ sampling 30% Sample Taker 2: TZ sampling 85% Who would you rather took your sample? Unless they audit TZ sampling,
sample taker 1 thinks they are doing a brilliant job
![Page 12: Quality Issues Cervical Sample Taker Training. Quality Assurance The NHSCSP is one of the best quality assured screening programmes QA guidelines cover.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649cc45503460f9498deba/html5/thumbnails/12.jpg)
Transformation zone sampling
This audit will be done for you during your training period
You should continue to audit this once qualified
How?

TZ sampling – Bath Feedback sheets TZ listed as Y, N or PM (postmenopausal)
Reports: Adequate cellular content. TZ cells present Adequate cellular content. TZ cells absent PM: adequate cellular content Inadequate: Unsatisfactory
![Page 14: Quality Issues Cervical Sample Taker Training. Quality Assurance The NHSCSP is one of the best quality assured screening programmes QA guidelines cover.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649cc45503460f9498deba/html5/thumbnails/14.jpg)
Assessment of TZ sampling - Southmead Laboratory
Sample quality codes located towards the bottom of the report form indicate presence or absence of TZ sampling
Usually 2 digits
![Page 15: Quality Issues Cervical Sample Taker Training. Quality Assurance The NHSCSP is one of the best quality assured screening programmes QA guidelines cover.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649cc45503460f9498deba/html5/thumbnails/15.jpg)

Southmead Lab - TZ sampling
11 First digit - refers to TZ sampling
0 = no TZ cells 1 = TZ cells present
![Page 17: Quality Issues Cervical Sample Taker Training. Quality Assurance The NHSCSP is one of the best quality assured screening programmes QA guidelines cover.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649cc45503460f9498deba/html5/thumbnails/17.jpg)
Squamous cell content
11 Second digit - refers to squamous
cell content 0 = Insufficient squamous cells 1 = Sufficient squamous cells
![Page 18: Quality Issues Cervical Sample Taker Training. Quality Assurance The NHSCSP is one of the best quality assured screening programmes QA guidelines cover.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649cc45503460f9498deba/html5/thumbnails/18.jpg)
Reprocessed samples (2 slides made from one sample)
5 digits will be seen:00411

Sample Taker Registers
![Page 20: Quality Issues Cervical Sample Taker Training. Quality Assurance The NHSCSP is one of the best quality assured screening programmes QA guidelines cover.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649cc45503460f9498deba/html5/thumbnails/20.jpg)
Sample taker register
Different areas have separate sample taker registers
Outside BNSSG? Check with your local laboratory about obtaining a
sample taker code asap
Bristol sample takers: Please register before taking a sample at:
nww.avon.nhs.uk/phnet/cervical.htm Upon registration a unique sample taker code is issued Inform register if you move practices (keep code unless
you move out of Bristol)

Sample Taker Register
Monitor initial training & update training Sample Taker Profiles
Bristol: Updated annually onto CTC website No. of samples taken No. of inadequates No. samples with TZ sampling (work out %age)
