A major randomised trial of screening for abdominal aortic aneurysms, and initiation of a UK national screening programme-Thompson

Summary of the impact

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.

Improving policy for sexual and reproductive health

Summary of the impact

Research by Professor Judith Stephenson and colleagues at the UCL Institute of Women's Health into the effectiveness of chlamydia screening has led to guidance to health policy makers in the EU about national strategies for chlamydia control, and has influenced NICE guidelines on the subject. In particular, our work has informed debate on the value for money of the National Chlamydia Screening Programme (NCSP). Stephenson advised the National Audit Office on this topic, and a resulting report led to the NCSP focusing on chlamydia testing in sexual health services and primary care rather than screening in low risk groups. These changes are expected to make considerable cost savings to the NHS.

Faecal Occult Blood screening and the prevention of deaths from colorectal cancer

Summary of the impact

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.

Improved child hearing tests for the best start in life

Summary of the impact

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.

Pulse Oximetry screening to detect heart disease in newborn babies

Summary of the impact

Congenital heart defects are a leading cause of infant death, accounting for more deaths than any other type of malformation and up to 7.5% of all infant deaths. Timely diagnosis is crucial for the best possible outcome for these children. However, the accuracy of current methods for screening for critical congenital heart defects (CCHD) before birth is variable and currently only detects these defects in between 35-50% of cases. Although around a third of remaining cases are picked up after birth, up to a third of children with a CCHD are sent home, where they may become unwell or die. Research led by Dr Andrew Ewer at the University of Birmingham has demonstrated that pulse oximetry is a rapid, safe, non-invasive, painless method of detecting the low blood oxygen levels associated with CCHD, and is also a cost-effective approach. As a result of Dr Ewer's research, Pulse Ox was recommended for adoption across the US in 2011 by the Secretary for Health and Human Services, and Dr Ewer has been instrumental in this screening approach being taken up worldwide. This research prompted a national UK review of screening for these conditions.

Inclusion of flexible sigmoidoscopy in the UK Bowel Cancer Screening Programme

Summary of the impact

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.

Developing the evidence base for a changing cervical screening programme in England

Summary of the impact

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.

Ethnicity and Screening for Sickle Cell/Thalassaemia

Summary of the impact

Antenatal screening aims to identify genetic carriers of sickle cell/thalassaemia in order to provide prospective parents with "informed choice". Throughout the period January 2008-July 2013, the NHS in England has used a Family Origins Questionnaire in connection with sickle cell/thalassaemia screening derived from our research programme. The original policy issue concerned whether or not it is possible/desirable to target antenatal screening for sickle cell/thalassaemia by means of an ethnicity question. The policy problem was that socially constructed "ethnicity" categories correspond imperfectly and to an unknown degree with actual prevalence of genetic carriers. The screening question based on our research now guides the offer of initial screening and/or further laboratory tests for all pregnant mothers in England.

The NHS Bowel Cancer Screening Programme: Psychological aspects of development and implementation

Summary of the impact

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%.

Introduction of Mass Screening by Once-Only Flexible Sigmoidoscopy in the English Bowel Cancer Screening Programme to Reduce Colorectal Cancer Incidence Rates

Summary of the impact

Research undertaken by Professor Atkin has identified a feasible, acceptable and cost-effective method of reducing colorectal cancer incidence and mortality rates, which involves a once-only flexible sigmoidoscopy screening for all men and women at around age 60. The supporting research involved publishing the evidence, developing a fail-safe, efficient, patient-friendly delivery system, developing a surveillance strategy following adenoma-removal, and testing in multicentre randomised trials. After 11 years, incidence and mortality rates were reduced profoundly in the trials, with no observed attenuation of effect. The entire screening strategy was rolled out in a national programme from 2013, with complete population coverage expected by 2016.
