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.
Impact: Health and welfare; a UK clinical trial of uterine artery embolisation (UAE), with five-year follow-up, defined the risk- and cost-benefit of UAE versus surgery.
Significance: The trial informed guidelines/recommendations internationally and changed clinical practice. Women worldwide can now make an informed choice about their treatment; economic factors have been quantitated.
Beneficiaries: Uterine fibroid patients, the NHS, healthcare providers.
Attribution: G. Murray, UoE, developed and delivered innovative trial methodology; clinical aspects led by University of Glasgow.
Reach: UK guidelines; worldwide (Australia, USA, Europe) effect on clinical practice that will impact up to 25% of women.
Research into primary care insomnia by the Community and Health Research Unit (CaHRU) has led to broad improvements in healthcare provision for insomnia, improved patient quality of life, informed national/international policy and practice in insomnia care and impacted directly on health professional practice and insomnia sufferers, initially in Lincolnshire spreading across the UK and internationally from 2008 to 2011. Direct effects on practice include changes in sleep management and reduced hypnotic prescribing through seminars, workshops, conferences and e-learning developed by the team; inclusion in UK policy, practitioner information, training materials and guidance on hypnotics has led to greater professional and public awareness of sleep management internationally.
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.
The emergency care team at Warwick Medical School has a strong track record of high-quality health sciences research encompassing evidence synthesis, health-services research and clinical trials. Our trials of a 03b2-agonist (salbutamol) in acute respiratory distress syndrome (ARDS) have influenced therapeutic recommendations in the International Sepsis Guidelines (2013), reducing the use of this potentially detrimental therapy. Our cardiac arrest research informed the 2010 international guidelines on cardiopulmonary resuscitation (CPR) led to the generation of new intellectual property, and prompted industrial collaborations to build new technologies, such as TrueCPRTM (2013). These have led to improved CPR practice and improved patient survival. Furthermore, our research has led to major policy changes and to a redesign of UK emergency healthcare, improving cost efficiency, the patient experience and clinical outcomes (e.g. 95% of patients were treated within 4 hours - up from 65%; and people leaving without been seen reduced to less than 5%).
Prof Tanner's research on surgical site infections (SSIs) has had a direct impact on both patient care and policy at local, national and international levels. It has resulted in a reduction in the number of SSIs, thus improving patients' quality of life, shortening lengths of stay in hospital and making substantial cost savings for the NHS. The research has led directly to the development of policy and guidelines for various bodies including the World Health Organisation, the Department of Health, NICE and the Joint Commission Accreditation Healthcare Organisations (USA), as well as locally in a number of NHS trusts. The post discharge SSI surveillance programme pioneered by Prof Tanner has led to an increase in the number of trusts in the UK undertaking post discharge surveillance.
In response to inadequately designed assessment systems for patients recovering from orthopaedic surgery, researchers from the University of Oxford developed a series highly reliable and sensitive patient recorded questionnaires, known as the Oxford Scores. Providing a set of standardised outcomes for appraisal and on-going monitoring of patients, the Oxford Scores enable the informed assessment of clinical outcomes. Used to predict and detect early failure of poorly performing surgical interventions, the Oxford Scores have been adopted by health providers and regulators worldwide, leading to policy and treatment guideline changes and significant improvements in the quality of life of patients.
The MRC Conventional versus Laparoscopic-Assisted Surgery In Colorectal Cancer trial (CLASICC) is the largest and most successful UK trial of a technology applied to general surgery. It addressed an area of huge clinical uncertainty, providing a rigorous evaluation of a new technology and enabling its safe and widespread implementation. The impact of CLASICC has been global, confirming the advantages for patients (quicker recovery) and healthcare providers (cost-effectiveness) and so influencing national and international policy in favour of the laparoscopic technique. It informed NICE guidance and led to a major DH initiative that has seen the UK become one of the largest providers in the world of laparoscopic colorectal cancer surgery. CLASICC is regarded as a benchmark surgical trial, combining high quality trial design with rigorous quality assurance, which has informed the design of many subsequent colorectal cancer studies.
Osteoarthritis affects 8.5 million people in the United Kingdom, accounting for a third of all years lived with disability. Our research has provided commissioners and third-sector organisations with accurate estimates of the size of the problem, policy-makers with evidence on groups at particularly high-risk, and clinicians with original evidence on better approaches to assessing and managing osteoarthritis in patients presenting to primary care. These key insights have supported advances in public health and health care policy debate, changes in legislation, and improvements in the quality of patient care through training and new national, European, and global guidelines for health professionals.
