Quality Assurance Statement

Screening data records are constantly updated. The databases used by Public Health Wales Screening Division are updated on a daily basis when records are added, changed or removed (archived). This might relate to when a person has been identified as needing screening; has had screening results that need to be recorded, or has a change of status and no longer needs screening respectively. Data is received from a large number of different sources with varying levels of accuracy and completeness. The Screening Division checks data for accuracy by comparing datasets – for example GP practice data – and corrects the coding data where possible. It should be noted that there are sometimes delays in data collection – for example a person might not immediately register with their GP if they move address. These delays will therefore affect the completeness of the data depending on individual circumstances. In addition, the reader should be aware that data is constantly updated and there might be slight readjustments in the numbers cited in this document year on year because of data refreshing.

1 IntroductionThis is the third annual statistical report published by Bowel Screening Wales (BSW). This report covers data for the financial year 2015/16, with the exception of coverage which was run on 1st October 2016 and displays the latest available figure. BSW was launched in October 2008 and aims to reduce the number of people dying from bowel cancer in Wales by 15% by 2020 in the group of people invited for screening. To achieve this aim the bowel screening programme must identify cancer early when treatment is more successful and also identify and remove polyps that may otherwise go on to become malignant. In the year 2015/16 Bowel Screening Wales diagnosed 205 people with cancers and detected and removed polyps in 1149 participants.

The proportion of colorectal cancers diagnosed by screening is greater in Wales than in England at 12% compared to an overall average for England and Wales of 10% (NBOCAP 2015). There are indications that the rate of emergency admissions for colorectal cancer has reduced in Wales since the bowel screening programme was implemented and this is currently being evaluated further.

Key messages about the programme

Bowel screening reduces your risk of dying from bowel cancer. Men and women aged 60 to 74 are invited to take part every two years. You may feel well even if you have early bowel cancer. Finding cancer

early gives you the best chance of survival. Bowel screening is a free NHS test that can be completed easily in your

own home. Screening will miss some cancers, and some cancers cannot be cured. Taking part in bowel screening is your choice. Read the information

pack carefully to help you make your decision.

Programme delivery The Screening Division of Public Health Wales is responsible for managing, delivering and quality assuring the programme. The programme employs a Head of Programme, administrative staff, nursing staff and Quality Assurance Advisors for Screening Colonoscopy, Pathology, Radiology and Surgery. The central screening laboratory is co-located with the administrative department and Cervical Screening Wales laboratory. Laboratory staff work across both laboratories.

Screening pathway



Eligible participants are identified on the Welsh Demographic System and invited for screening. Men and women aged 60 to 74 years are invited every 2 years. Invitation is based on date of birth not geographical location and comprises a letter from the Director of Screening Division and an information pack which contains the test kit. The initial test kit is a Guaiac Faecal Occult Blood (FOBt) test kit which is sent to eligible people by post for completion at home and returned to the central screening laboratory by post in the prepaid envelope provided.

People with negative FOBt results are returned to routine recall and invited again for screening two years later, if they remain in the eligible age range. Those with equivocal results are sent a more sensitive FOBt called an immunochemical test (FIT) to complete.

Participants with positive results are invited for telephone assessment with Specialist Screening Practitioners (SSP) based in Local Assessment Centres who assess their fitness for colonoscopy. Most assessments are undertaken by telephone, but face to face appointments are available at request or if considered necessary by the SSP.

If considered fit, colonoscopy is offered to the participant and, if accepted, this is undertaken in the participants Local Assessment Centre. Depending on the findings after assessment, participants are returned to routine recall, put onto a surveillance programme according to the number and size of polyps identified and removed, or referred to the multi disciplinary team with a diagnosis of cancer.

If someone is not fit for colonoscopy, a CT scan is usually offered.

2 Headline statistics Bowel Screening Coverage on 1st October 2016 was 51.7%, compared

to 50.3% on 1st October 2015. Coverage on 1st October 2016 ranged from 50.1% in Cardiff and Vale University Health Board to 52.7% in Aneurin Bevan University Health Board.

Bowel Screening Uptake for those participants invited between April 2015 and March 2016 was 54.4%, an increase from the previous year when uptake was 50.8%. Uptake in 2016 ranged from 52.5% in Cardiff and Vale University Health Board to 55.6% in Powys Teaching Health Board.

Coverage and uptake figures were higher in females (coverage was 53.6% in females compared to 49.8% in males, uptake was 56.3% in females compared to 52.3% in males).


http://www.bowelscreeningwales.wales.nhs.uk/


Coverage and uptake figures were also higher in those living in the least deprived areas (58.4% and 61.4% respectively in the least deprived areas compared to 42.7% and 44.7% respectively in the most deprived areas).

For the period April 2015 and March 2016:

284,400 participants were invited for bowel screening.

164,400 test kits were validated of which 1.4% were spoilt and a further 2.5% rejected, which could not be tested.

4.1% of all Faecal Occult Blood (FOB) test kits were validated with an equivocal result, these participants were sent the Immunochemical test kit (FIT).

151,800 test kits were given a definitive result, 98.7% were negative and 1.3% were positive.

91.3% of all test kits were validated and a result letter issued to the participant, within a week of receipt by the laboratory.

Across Wales, 81.4% of participants were offered an index colonoscopy or flexible sigmoidoscopy within four weeks of phoning to make the appointment with a Specialist Screening Practitioner. This is a significant improvement from 59.0% in 2014/15. In 2015/16 98.7% of participants were offered a procedure within eight weeks.

Attendance at first (index) colonoscopy or flexible sigmoidoscopy was 97.3% with over 1,700 attended index procedures.

At first (index) colonoscopy or flexible sigmoidoscopy, cancer detection rate was 12.0%, polyp detection rate was 67.0% and the adenoma detection rate was 52.8%. A colorectal polyp is a growth found on the lining of the colon or rectum. A neoplastic polyp (a tissue whose cells have lost its normal differentiation) is called an adenoma, which is a benign growth but in some cases can develop into a cancer.

205 participants were diagnosed with cancer and 1149 participants had polyps detected and removed in the year.

Across Wales, the proportion of booked computer tomography (CT) scans which were attended was 97.0%.

Bowel screening uptake has seen a significant increase during 2015/16 from 50.8% the previous year to 54.4% this year. Work to increase uptake is ongoing and includes work to increase uptake across the population as well as specifically in groups where uptake is low. The BSW team have implemented various interventions to improve uptake including an introductory letter which is sent to men in advance of their invitation for screening. Uptake has increased across all the deprivation quintiles, not just in the least deprived groups. Also, the absolute and relative difference between the most and least deprived groups is decreasing, meaning that inequity in uptake is reducing.

Note: Spoilt and rejected rates are calculated as a percentage of the total results.

Equivocal rates are calculated as a percentage of the equivocal, negative and positive results.

Negative and positive rates are calculated as a percentage of negative and positive results only.

During 2015/16, we have introduced a new rejected category. This has allowed BSW to compare rates with other UK programmes that use these definitions.

Across Wales in 2015/16 91.3% of all test kits were validated and a result letter issued to the participant within a week of receipt by the laboratory. This is a reduction from the 98.7% seen last year, and is a result of new technology being introduced into the cervical screening laboratory. Laboratory staff work across both the bowel and cervical screening programme and needed to be trained to use new equipment in the cervical laboratory. This



had a temporary impact on staffing levels within the bowel screening laboratory. Staffing levels have since returned to normal and turnaround times have improved.

3.7 Waiting times for index colonoscopy/ flexible sigmoidoscopy appointment within 4 weeks of Booking SSP Appointment

During the April 2015 to March 2016 year, 1723 participants were offered an index procedure and 1402 (81.4%) were offered a procedure date within 4 weeks of booking their Specialist Screening Practitioner (SSP) assessment appointment. A total of 1701 (98.7%) were offered a procedure date within 8 weeks and 22 (1.3%) were offered a procedure date more than 8 weeks after booking their SSP assessment appointment. This is a large improvement on waiting times reported during 2014-15 where 59.0% of participants were offered an index procedure within four weeks.

3.8 Attendance at CT scansAcross Wales, 97.0% of booked CT scans were attended; this varies between 92.2% and 100% across Health Boards for the year April 2015 to March 2016.



4 DefinitionsThis section provides further detail on the calculations used in this report.

Eligible For coverage calculations, eligible participants are those that are resident in Wales at the time of reporting, that are not currently ceased or suspended from bowel screening invitation following notification of a diagnosed bowel condition, movement or death and are between invite age range 60 to 74 years.

For uptake calculations, eligible participants are those that were resident in Wales (not deducted on NHAIS in the 6 months following invitation) and invited for bowel screening during the reporting period date range. Participants that were ceased or suspended from bowel screening invitation following notification of a diagnosed bowel condition, movement or death, within six months following invitation were excluded, unless they had returned a used test kit.

Uptake Participants were deemed to have responded to their invitation if the bowel screening programme received a used test kit within six months following their invitation.

CoverageThe calculation counts those eligible participants that have had a used test kit validated within two and a half years of the reporting date.

Deprivation Deprivation quintiles were assigned using the Welsh Index of Multiple Deprivation (WIMD) 2008, measured at lower super output area (LSOA) level. LSOAs are ranked into quintiles at an all-Wales level so they can be compared between health boards. This means that there will not be an equal proportion of people in each quintile when you look at each health board e.g. in Monmouthshire, 40% of the population live in the least deprived quintile of Wales, but no areas fall into the Welsh most deprived quintile.

Health Board This is health board of residence.

Spoilt test kit A spoilt kit is a FOB/FIT kit that is rendered unavailable for testing either by the participant or by the laboratory for reasons defined in the Bowel Screening Wales and Laboratory Quality Manuals, e.g. no date on the kit or the test not completed well by the participant.The rates are calculated as a proportion of the total bowel screening test kits validated in the reporting period.



Rejected test kit A rejected kit is one that is rejected for testing by the laboratory because it fails to meet defined specific criteria for sample acceptance that are documented in the Laboratory Quality Manual e.g. a mismatch between the name and the barcode or a kit that is past the manufacturers expiry date. These rates are calculated as a proportion of the total bowel screening test kits validated in the reporting period.

Equivocal test kit These rates are calculated as a proportion of the un-spoilt bowel screening test kits validated in the reporting period.

Negative and positive test kit These rates are calculated as a proportion of the test kits validated in the reporting period as negative and positive results – i.e. those kits that have a definitive result.

Prevalent Round - first invite (table 1f)Prevalent round first invitation is the first time a person is invited to take part in screening. They have not been screened before as they have not been invited before.

Prevalent round - subsequent invite (table 1f)Prevalent round subsequent invitation is when a person has previously been invited, but has not actually taken part in screening before. They have not been screened before but they have been invited before.

Incident Round (table 1f)Incident round is when people are invited that have previously taken part in the screening programme.

ColonoscopyColonoscopy is the visual inspection of the interior of the colon with a flexible, lighted tube (colonoscope) inserted through the rectum. During colonoscopy, biopsies (tissue samples of abnormal areas) can be obtained to aid diagnosis.

Flexible SigmoidoscopyA flexible sigmoidoscopy is the visual inspection of the lower part of the large intestine with a flexible lighted tube inserted through the rectum. During flexible sigmoidoscopy, biopsies (tissue samples of abnormal areas) can be obtained to aid diagnosis. Attendance and detection rates (Tables 5 and 6) report procedures that are booked in the reporting period. Waiting times were calculated using those participants with an index procedure first offered within the reporting period. This might not be the procedure they attended, due to participant choice or other factors.
