Approximately 25,000 people in the UK die each year from venous thromboembolism (VTE); furthermore, VTE affects 1 in 100,000 women of childbearing age and causes one-third of all maternal deaths. Thrombophilia, pregnancy and the use of oral oestrogens can all place women at increased risk of VTE when compared with other individuals. University of Glasgow researchers quantified the probability of VTE among at-risk women and analysed the benefits and cost-effectiveness of thrombophilia screening. Their research is cited in the recommendations and evidence bases of leading national and international clinical guidelines. This work also galvanised an overhaul of VTE prevention policy within NHS Scotland by emphasising the need for regional health boards to implement and audit standardised in-house protocols and provide accessible patient information on VTE.
Pre-pregnancy care (PPC) significantly reduces the risk of poor pregnancy outcomes among women with diabetes. Yet, lack of awareness has resulted in poor participation, with two thirds of women receiving suboptimal PPC (CEMACH, 2007).
An innovative preconception counselling resource (DVD/website) to inform women about PPC and improve pregnancy outcomes is embedded in routine care in Northern Ireland and beyond since 2010. The UK's first widely distributed multimedia preconception counselling resource for women with diabetes is already having a significant impact on pregnancy planning. In early evaluation results 76% of all pregnant women with diabetes in Northern Ireland reported receiving PPC.
Professor Peter Sasieni's team at Queen Mary showed that the efficacy of cervical screening was age-dependent. Their recommendations were adopted as policy in England in 2003 and led many other countries, including the USA, to raise the recommended age of first screening. This research was central to the 2009 re-evaluation of the most appropriate age for first screening in England, resulting in some 300,000 fewer screening tests per year in women aged 20-24, with a cost saving to the NHS of some £15 million annually. Annually, 45,000 fewer women now have an abnormal cervical screening test, of which an estimated 8,500 would have received unnecessary surgical treatment. The estimated annual saving to the NHS is £17.5 million.
Around 2.5 million people in the UK have Type 2 diabetes, with many more in a pre-diabetic state, Both conditions are hard to detect and frequently remain undiagnosed and untreated for years. The cost burden to the NHS of eventual treatment is estimated at £10 billion; 80% of which is spent on complications that are, with good care, avoidable. Targeted diabetes prevention programmes could aid in prevalence reduction and associated costs. Leicester's Diabetes Research Centre has developed two risk scores, both suitable for use with an ethnically diverse UK population, to detect these conditions: a self-assessment questionnaire and a general practice database tool. Recommended by NICE, they have been used successfully in varied settings. Since July 2011, around 260,000 people have completed the self-assessment score online and more than 40,000 through other means.
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.
Research conducted by LSHTM has played a key role in supporting the global elimination of congenital syphilis. Two studies providing evidence of the health burden of congenital syphilis in Africa and the effectiveness of benzathine penicillin treatment form a pillar upon which WHO established its new syphilis elimination initiative. Further research has resulted in the adoption of new point-of-care tests for screening pregnant women for syphilis in 30 countries. As a result, more women are diagnosed and fewer babies die of syphilis.
This case study is based on two areas of research, both focused on young women's sexual health, conducted by Hoggart and Newton between 2009 and 2013. The first concerns abortion, and the second concerns long-acting reversible contraception (hereafter LARC). The research has had the following impacts: sexual health policy has been influenced; the delivery of sexual health service has changed; guidelines have been informed; practitioners have used the research findings; new clinical processes have been adopted; professional training has been influenced by the research; and industry has invested in research.
This research significantly improved the accuracy of antenatal screening for Down's syndrome and the extent to which maternal choices are informed by robust evidence. Tests developed by Professor Nick Wald's team at Queen Mary's Wolfson Institute of Preventive Medicine and validated in the SURUSS (Serum Urine and Ultrasound Screening Study) study were adopted as national UK policy in 2003 and remain an established gold standard worldwide. As a result, most Down's syndrome babies in UK are now born through parental informed choice, and (using age-adjusted figures) approximately 3,000 fewer babies with the syndrome were born between 2008 and 2013. Screening programmes in numerous countries are based on this research.
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 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.
