This case study outlines the impact of novel omega-3 fatty acid therapy for sickle cell disease on health and policy. 128 patients on the treatment since 2010, and another 300 who started to receive it in June 2012 have seen remarkable improvements in health and quality of life as assessed by reductions in hospital admission and absence from work/school due to the disease. A panel of experts set up by the Ministry of Health of Sudan to evaluate the evidence recommended the integration of the therapy in the management of the disease in a policy report dated December 20, 2012. The Ministry has accepted the recommendation.
Severe Limb Ischaemia (SLI), in which there is reduced blood flow to the leg(s), is the commonest cause worldwide of gangrene and limb loss. The BASIL trial, led by Professor Andrew Bradbury at the University of Birmingham, was the first (and remains the only) randomised controlled trial to investigate whether surgical bypass or endovascular (`keyhole') treatment is best at relieving symptoms and preventing amputation and/or death in patients with SLI. The outcomes of the study have been of worldwide interest, and the recommendations put forward by the team have been endorsed by a number of high profile clinical organisations. These findings are also nowincorporated within a series of national and international guidelines on SLI.
A low-cost, efficient, blood cell salvage technology (HemoSep) has resulted from research carried out at Strathclyde between 2008 and 2013. The novel technology has been patented and licensed to Brightwake Ltd., who manufacture the device in the UK and market it through a global distribution network. HemoSep has now been used in clinical centres across Europe, North America, and South Africa since its commercial launch in late 2012. The use of the device has been shown to reduce the need for donor blood transfusions in open-heart surgical patients by at least 1 unit (450 ml) with an associated reduction in transfusion related complications such as heightened inflammatory response and bleeding. The reduction in blood transfusions associated with the use of HemoSep has a considerable cost benefit to healthcare providers (in North America blood costs up to $1600 per unit). In addition, commercialisation of HemoSep has led to the creation of new manufacturing, marketing and sales jobs in the UK and overseas.
Between 1996 and 2013 researchers at Swansea University evaluated service initiatives and changing professional roles associated with the management of patients with debilitating gastrointestinal disorders. This work showed the clinical and cost effectiveness of two main innovations: open access to hospital services for patients with inflammatory bowel disease; and increased responsibility for nurses, particularly as endoscopists. Our evidence has had a broad, significant impact on: national policy through incorporation in NHS strategies, professional service standards and commissioning guides; service delivery through the provision of increasing numbers of nurse endoscopists and the wide introduction of nurse-led open access to follow-up; and patient care, as documented in sequential national audits in 2006, 2008 and 2010.
A Cardiff researcher has led an International 15 year programme resulting in multiple novel findings which have led to changes in the recommended diagnosis and treatment of acquired haemophilia A (AHA). The research has, for the first time, allowed the comparison of immunosuppressive regimens for inhibitor eradication and comparison of the efficacy of treatment strategies to control bleeds. Studies led directly to the production of UK and International guidelines on the management of AHA with 14 of the 18 specific recommendations in the UK guideline being underpinned by Cardiff-led research.
University of Bristol researchers at the Bristol Heart Institute (BHI) have pioneered the development and clinical take-up of the novel technique of off-pump coronary artery bypass (OPCAB) surgery. Over ten clinical trials and several large cohort analyses have assessed the impact of this technique on elective and high-risk patients. The results have shown that it is as safe as the conventional coronary artery bypass grafting (CABG) technique that uses a cardiopulmonary bypass pump and cardioplegic arrest. Most importantly, however, OPCAB significantly reduces the risk of post-operative complications, and reduces morbidity and mortality. It also uses less hospital resources, reducing time in intensive care and length of hospital stay. In 2011 (the last year for which data are available), 20% of CABG operations in the UK were carried out with the OPCAB technique and it has had significant take-up overseas (for example, 18% of CABG operations in the US and 21% in the EU in 2010). NICE has recommended the safety and efficacy of OPCAB surgery.
Research at UCL on human haemolytic anaemias known as the `hereditary stomatocytoses' has improved diagnosis of these conditions, meaning that patients now avoid unnecessary and potentially life-threatening splenectomies, and inappropriate investigation and treatment for raised potassium levels. Identification of a common single nucleotide polymorphism that causes apparently normal red blood cells to leak salt when cooled (as is normal procedure with donated blood) has raised awareness of this issue in the NHS Blood and Transfusion service, with the result that individuals with this condition have been identified among existing donors, and work is underway to develop a screening method to exclude such individuals from donating blood that cannot be stored safely. Finally, the research has facilitated diagnosis of the recessive metabolic disorder phytosterolaemia by blood count, allowing these individuals to be given appropriate dietary treatment to control their cholesterol levels.
King's College London (KCL) research has made a major contribution to improving the quality of life for patients who have anaemia linked with chronic kidney disease. Studies undertaken by KCL researchers established that intravenous iron supplementation was required in anaemic patients with advanced kidney disease, in whom oral iron therapy was ineffective, and defined the best regimes for administration of intravenous iron. Subsequent KCL work on drugs that stimulate production of red blood cells (erythropoiesis) defined the target levels of haemoglobin to aim for in chronic kidney disease patients. Most recently, KCL researchers made the key discovery that the novel drug peginesatide for the first time enables the rescue of patients who develop a rare and potentially fatal reaction against erythropoietin (which is the commonest treatment for anaemia in chronic kidney disease). These KCL research studies have had a significant impact by making a major contribution to national and international clinical guidelines, including UK NICE guidelines and the 2012 National Kidney Foundation KDIGO Clinical Practice Guideline for Anemia in Chronic Kidney Disease.
In response to the gap between standards and the reality of preventive cardiovascular disease (CVD) health care delivered across Europe, Imperial College researchers developed an innovative nurse-led, multidisciplinary, family centred, CVD prevention programme (EUROACTION) and led its evaluation in hospital and general practice across 8 European countries. We showed that patients and their families in our programme can achieve healthier lifestyles and better risk factor management compared to usual care and these differences were sustained out to one year. We then adapted our learning from EUROACTION for the NHS, by integrating secondary and primary prevention into one community service (MYACTION), and managing cardiovascular disease as a family of diseases with common antecedents. To train doctors, nurses and allied professionals to deliver MYACTION we created an MSc in Preventive Cardiology which is now in its 6th year. EUROACTION is now recommended as an evidence based model of care in current European CVD prevention guidelines, and MYACTION is being commissioned by the NHS in London, and Galway, Republic of Ireland, and by the Western Isles Health Board. Our research has impacted directly on the development and delivery of high quality preventive care in both Europe, and the NHS, and on the training of doctors, nurses and allied health professionals in preventive cardiology.
Research by LSHTM has alerted international health bodies, the UK and US militaries, politicians and doctors around the world to a new trauma treatment that could save over 100,000 lives each year. A proactive advocacy campaign following the publication of the CRASH-2 trial in The Lancet has secured media coverage in major global news outlets, the inclusion of the drug tranexamic acid (TXA) on the WHO List of Essential Medicines and direct endorsements from WHO officials, UK ministers and army figures. TXA was the first drug to be approved under the UK government's Medicines Innovation Scheme.
