Patients are more likely to get the most effective healthcare, at affordable cost to the NHS, as a result of research methodology, developed by researchers at the University of Bristol, that allows the efficacy and cost-effectiveness of multiple treatment options to be compared, based on all the available evidence, much more efficiently than in the past. Since 2008, these methods have been used to inform Clinical Guidelines issued by the National Institute for Health and Care Excellence (NICE) and in submissions to NICE's Technology Appraisals. Guidance in NICE's Technology Appraisals is mandatory and therefore impacts directly on clinical practice. The methodology is used in decision making by NICE's equivalents in other countries including Canada, Germany, and South Korea, and by consultancy firms that conduct analyses for pharmaceutical companies.
Methods for valuing quality of life developed by Professor Devlin at City University London are used internationally to help governments make healthcare decisions. Her research focuses on a widely-used questionnaire for measuring patient reported health, the European Quality of Life 5-Dimensions (EQ-5D). Government organisations routinely use the EQ-5D to judge whether new medicines work and are cost-effective. Over 15 countries are undertaking EQ-5D studies using Professor Devlin's methods to inform decisions on pricing and provision of new medicines. These developments have been achieved through active dissemination to the academic community and governments and through Professor Devlin's scientific leadership of the European Quality of Life (EuroQol) Group. The impact of this research is highly significant in improving health and health care decision-making and has had wide reach throughout the UK and in many other countries.
Depression is a major public health problem, producing substantial deterioration in health and well- being and costing the UK £billions annually. A programme of research at Exeter, led by Professor Richards, (trials and Phase IV implementation studies) has changed national policy on the treatment of depression (NICE guidelines). It has also underpinned the UK's Improving Access to Psychological Therapies (IAPT) programme which has been widely implemented, leading to new treatment for over 1 million people, with a recovery rate in excess of 45%, and over 45,000 people coming off sick pay and benefits. The research has also achieved International impact.
Public financing of health services in low income countries was challenged by the World Bank's Agenda for Reform in 1987, which advocated increased roles for private sector, private insurance and user fees. This was followed by a wave of reforms implementing this approach. McPake has been involved in researching the implications of this shift since this period and has published a series of influential articles that have had a demonstrable impact on this debate. Removal of user fees for all, or selected, services or for selected population groups has occurred in many countries, including 28 of 50 countries with the highest maternal and child health mortality included in a recent survey (http://bit.ly/17FUiDM). Witter is the lead researcher who has examined country level experiences of removing fees and it is demonstrable that her work has been applied in specific countries to shape the details of policy and has also had a major influence on the global debate.
Many hand surgical units worldwide have routinely used night-time splints in all patients after Dupuytren's contracture fasciectomy and dermo-fasciectomy, despite the lack of robust evidence to support its use.
Jerosch-Herold's programme of research identified that routine night-time splinting for all patients after fasciectomy or dermo-fasciectomy surgical treatments for Dupuytren's contracture is not beneficial. This finding is changing clinical practice, and informing guidelines and policies in the UK, New Zealand and the USA. As a result, health care organisations are ceasing to prescribe routine night-time splinting. This reduces inconvenience and discomfort for patients, relieves pressure on services and generates financial savings, all whilst maintaining equally good clinical outcomes.
The reach of the research findings impact is high, as Dupuytren's contracture is a common disorder of people of Northern European ancestry which results in surgical interventions for thousands of people annually (13,000 pa in the UK alone).
University of Sheffield research which evaluated the clinical and cost-effectiveness of statins for the primary and secondary prevention of cardiovascular events has directly led to an additional 3.3 million people in England and Wales becoming eligible for this treatment. Statins have been shown to reduce the risk of future cardiovascular events, such as heart attacks and stroke.
Guidance on statin prescribing in England and Wales, issued by the National Institute for Health and Care Excellence (NICE) Appraisal Committee in January 2006 was informed by our research report. Following this guidance the number of patients receiving statins has increased year on year with the number of prescriptions increasing by 29% between 2007 and 2011, enabling these patients to benefit from reduced risk of heart attacks and stroke and CVD related deaths.
Research at York has had a direct impact on national guidance about the use of health technologies in the NHS. It provided methods that are used to assess whether a technology is expected to be a cost-effective use of NHS resources, how uncertain this assessment is likely to be and whether additional evidence is sufficiently valuable to recommend further research to support its widespread use. It has had an impact on the technologies available in the NHS and the evidence available to support their use: improving patient outcomes; saving NHS resources and strengthening the evidence base for clinical practice. It gives an explicit signal and incentive to manufacturers; informing development decisions and the type of evidence collected. It has had an international impact on how the adequacy of evidence is judged and research is prioritised; particularly in recent reforms in the United States (US) where the principles of this value of information (VOI) analysis are informing the prioritisation of $3.8bn for `comparative effectiveness research'. It has also informed the methods used in low and middle income countries, especially national agencies in health care systems in South East Asia and South America, as well as global funding bodies.
Paracetamol self-poisoning is a major cause of liver failure and death. Research by Professor Keith Hawton and colleagues in Oxford in the 1990s revealed the extent and characteristics of the problem, and led to UK legislation to restrict pack size in 1998. Hawton and colleagues then showed that this was followed by a substantial reduction, over 30%, in the number of deaths from paracetamol poisoning. Importantly, a 2013 analysis shows that the benefit has been sustained and is not diminishing, with an estimated 374 fewer deaths in the UK since 2008. Registrations for liver transplants due to paracetamol toxicity have also decreased. As a result of these benefits, three other countries have introduced similar restrictions since 2008.
A programme of methodological research undertaken by the University of York has shaped the economic evaluation methods used by the National Institute for Health and Care Excellence (NICE) since its inception, to assess the cost-effectiveness of healthcare interventions. Therefore the methods developed by York underpin many of the healthcare decisions by NICE on which new and existing interventions and programmes should be funded and used in the NHS. The methods used by NICE have also had a major influence on the approach taken to technology assessment internationally and so York's underpinning research has had wide impact beyond the UK.
Professor Irving Kirsch has conducted a meta-analysis of both published and unpublished clinical trials of antidepressants (Kirsch et al., 2008). This analysis demonstrates that the effects of antidepressants are mostly placebo effects except with extremely severe depression. The analysis opened an international debate on antidepressant efficacy, influenced NICE guidelines for the treatment of depression (NICE, 2010), and led the scientific committee of the European Medicines Agency to reconsider its own approval of antidepressants (Broich, 2009). It also informed public opinion through widespread media coverage, and produced intentions to change prescribing habits among 44% of surveyed UK doctors. Public awareness of Kirsch's work is such that a class action has been taken against Pfizer, a large pharmaceutical company, and the Vatican has convened an international study meeting (14-15 June, 2013) to produce new recommendations for the treatment of depression.
