Our evidence that a single flexible sigmoidoscopy (FS) dramatically reduced bowel cancer mortality and incidence, combined with evidence of high public acceptability in our pilot programme, led the Prime Minister to announce in late 2010 that once-only FS would be included in the UK National Bowel Cancer Screening Programme. The new FS screening programme started in March 2013 in six pilot centres, and is being progressively implemented nationally, with full roll-out expected by 2016. All eligible adults will be invited for screening around the time of their 55th birthday using the invitation and bowel preparation protocols developed for the trial. If uptake rates similar to those in the pilot are achieved, bowel cancer rates could be cut by a quarter, and deaths by a third, giving the UK the best colorectal cancer (CRC) outcomes in the world.
The Institute of Sound and Vibration Research (ISVR) has played an influential role in transforming testing for child deafness in Europe, North America and elsewhere. In England, the NHS drew on its findings in deciding to replace traditional testing methods with universal newborn hearing screening programmes. This form of testing is more accurate, cost-effective and can be conducted at an earlier age. In England alone more than four million babies will be screened between 2008 and 2013, with around 6,000 identified as having hearing impairments. Earlier clinical intervention has benefited children's language development and overall quality of life.
The results of two major randomised trials and a cohort study based at the University of Manchester (UoM) have had a major impact on cervical screening in the UK and influenced thinking internationally. These trials evaluated two technologies which had the potential to improve cervical screening. As a result HPV primary screening has moved to a large national pilot study. HPV as a test of cure following treatment of cervical precancerous lesions has now been adopted as standard across the National Screening Programme. Automation assisted technology, which was shown to be inferior to manually read cytology, will not be adopted.
The UK Faecal Occult Blood Test Screening Programme, based on Dundee-led research (Steele), offers bowel cancer screening through mailed test kits followed up with colonoscopy when faecal blood is detected. It is estimated to prevent about 2,000 UK deaths annually. Steele's Screening Research Unit also trialled immunological faecal occult blood testing, which was subsequently incorporated into the Scottish screening algorithm. In addition to demonstrating a 27% reduction in bowel cancer deaths through participation in Faecal Occult Blood screening, the Unit has researched the incidence of interval cancers and the impact of repeated invitations, development of new tests, and strategies for increasing participation. All of these drive the National Screening Programme, and will further reduce mortality.
Three national, multicentre randomised controlled trials and associated studies during a 20-year research programme on abdominal aortic aneurysm (AAA) led by Imperial College researchers have altered international practice. The United Kingdom Small Aneurysm Trial (UKSAT) set the threshold for intervention at 5.5cm to repair AAAs. Population screening programmes and guidelines in Europe (UK, Sweden and Europe as a whole), Australia and the United States are based on these data. The results from EndoVascular abdominal Aortic Repair (EVAR) trials have informed international audits, guidelines (including NICE) and task forces in the same countries.
Abdominal aortic aneurysm (AAA) is a major cause of death in older men, in the UK and elsewhere. A large UK trial led by the University of Cambridge evaluated the long-term benefits of ultrasound screening for AAA in men aged 65-74 years. This provided the basis for the introduction of a UK national AAA screening programme in men aged 65; this was announced in 2008, initiated in 2009, and achieved full coverage of England in 2013. Similar screening has started in Sweden, New Zealand and in parts of Italy, and is being actively discussed in Denmark, Norway and Finland.
Abdominal aortic aneurysms (AAAs) affect more than 4% of British men aged 65-74 and are responsible for over 6,800 deaths annually. The MASS trial showed that screening could reduce AAA-related mortality by 42%, and the Health Economics Research Group (HERG) demonstrated, through the MASS trial, that AAA screening was cost-effective. HERG thus helped inform the policy announced by UK ministers in 2008 to introduce a national screening programme for all men reaching 65. By Spring 2013 it was fully introduced in England — offering screening to 300,000 men annually; the latest Annual Report (2011-12) claimed an uptake rate of 75%. In 2008 the DH estimated the health gain from a screening programme would be at least 130,000 QALYS over 20 years. Internationally, MASS is the most significant trial of AAA screening, and provides the most robust evidence-based model of its cost-effectiveness. It extensively influenced AAA screening guidelines, policies and services, including in the USA and Europe.
The Nottingham Bowel Cancer Screening trial showed that biennial Faecal Occult Blood testing reduced bowel cancer mortality by 16%. As a consequence of this trial, the Department of Health launched two screening pilots and introduced a National Bowel Cancer Screening Programme (NBCSP), achieving national coverage in 2010. Since 2008, this has sent out almost 18 million invitations and detected 16,000 bowel cancers, of which 21.6% were early cancers with a 95% chance of cure. It is estimated that the NBCSP saves around 3,500 lives each year in the UK. International screening programmes modelled on the UK system will save many more.
Essex contributed to the independent evaluation of the UK NHS Bowel Cancer Screening Pilot programme by conducting the psychosocial aspects of this research. The evaluation recommended full roll-out, and was used to inform the programme's subsequent development and implementation. Nationwide screening for 60-69 year olds, using the Faecal Occult Blood test, began in 2006 and in 2010 the programme was extended to include adults up to their 75th birthday. Since July 2006 over 17 million screening episodes have been completed and 15,000 cancers detected. It is estimated that the programme is on track to cut deaths by 16%.
Karl Atkin participated in a research programme that explored ways of best supporting those with or at-risk of sickle cell and thalassaemia from the perspective of patients, families, practitioners and policy makers. The findings have had an accumulated impact on: care standards for a range of health care professional and national policy bodies; public outreach; ante-natal care and screening policy; and have informed the training and education of doctors and nurses on how best to communicate with those at risk of inherited blood disorders. Findings have also contributed to the evidence base on social care and education, including providing practical guidance to teachers.
