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.
IOE researchers have helped the NHS to maximize the number of babies in the UK who are screened for a range of serious but treatable conditions when they are about a week old. This means that more children with one of the screened-for conditions can start a course of treatment quickly. The fruits of the IOE team's work — a suite of training materials for healthcare staff and information leaflets for parents — have had another important consequence. They have enabled parents in the UK and in other countries to make much more informed decisions on screening than they could in the past.
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%.
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.
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.
Research at UCL developed a `screen and treat' model for dealing with mental health problems in the aftermath of disasters. This was successfully implemented after the London bombings in 2005. The strategy was shown to be very effective in detecting individuals in severe psychological need, and those screened and referred within the programme benefited substantially from evidence-based treatment. Since then, the model has been adopted in planning for major incidents in the UK and abroad. The screening instrument developed at UCL is in widespread use around the world.
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.
University of Glasgow researchers have played a pivotal role in developing and evaluating the pioneering Childsmile oral health improvement programme. By the late 1990s, more than 50% of 5-year-olds in Scotland showed evidence of dental decay. Since implementation of Childsmile in 2006, this has decreased to 33% and, within this population dental decay in children from the most severely deprived backgrounds has experienced a striking reduction (from 79% to 55%). In 2011, Childsmile was formally incorporated into the primary care dental contract and subsequently in 2012, into the universal child health surveillance programme in Scotland. Since its introduction Childsmile's community-based, preventive approach has revolutionised dental healthcare from birth for all children up to 12 years of age in Scotland resulting in delivery of Childsmile to over 730,000 children per year.
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 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.
