The development, review and acceptance of an explicit 'safety case' forms a key component of the assurance and regulation of many safety critical systems, including those in the nuclear, defence, railway, automotive, medical device, and process industries. Industrial practice in safety case development prior to York's development of the Goal Structuring Notation (GSN) relied almost exclusively upon narrative text to communicate the safety argument within the safety case. This approach suffered from problems of lack of clarity, difficulty in comprehension, poor structure, and limited formalised development of 'case law' in safety argumentation. GSN was developed and matured by York to tackle these problems directly, and is now used internationally by safety critical industries in a large number of domains including defence, transport, nuclear and medical devices.
Developed from Loughborough University research into the employee impact of safety management, the Loughborough Safety Climate Assessment Toolkit (LSCAT) has helped change attitudes and raise awareness across a variety of industry sectors. Freely available in the public domain, it has facilitated the assessment of safety climate as part of a process of culture change and wider management system enhancement. Beneficiaries during the impact period have included the Royal College of Nursing and the NHS, which have used the tool as a "fundamental" means of benchmarking best practice, and logistics giant DHL Supply Chain, which has used it to identify specific areas for improvement in its safety management systems.
Research at the Transport Safety Research Centre (TSRC) at Loughborough University has led to the development of a new road safety data and knowledge base called the European Road Safety Observatory (ERSO). The European Commission has confirmed in a reference that it has become a standard tool for EU and national level safety policy development and has been praised by the European Parliament. Since being established in 2006 it has been emulated at national level by many EU Member States including the UK, Spain, Czech Republic, Netherlands and France. The ERSO website now receives over 5000 hits each month from road safety policy-makers across the EU. The research, which was led by TSRC researchers, was conducted between 2004 and 2012 and in 2013 was awarded the HRH Prince Michael International Road Safety Award for its impact on road safety.
Failure of critical computer systems could result in death, injury, financial loss and damage to the environment. To help address this concern, academic staff at City University London have developed an approach to assurance case construction to demonstrate that the risk posed by critical computer systems is acceptably low. Initially the primary focus was the justification of safety-related systems in UK industry (i.e., by introducing more structure and rigour) but it has been extended to cover other aspects such as reliability and security and has been taken up internationally. This approach has been commercialised by a company with close links to City University London (Adelard LLP). The approach is used in critical areas including:
Industry feedback has been positive and our assurance approach, in the form of updated regulations and procedures, has been adopted as standard practice in these sectors. This has led to significant and wide-ranging impact on practice and the consequent safety and security of systems, benefiting both the industries concerned and the public who use or are affected by their services.
In response to the University's strategy on improving standards in professional practice, several research projects were undertaken in health and safety management, procurement, transport planning, energy management, and professional practice. These focused on improving standards of professional practice in construction management, energy management, facilities management, and sustainable transportation planning. Two projects resulted in sector guidance, whilst two others had a direct impact on practice in the University. Another has influenced the way cycling use data is collected by the two leading organisations in this sector. This case study demonstrates the impact on professional practice linked to the university's vision.
The European Air Traffic Management system currently handles around 26,000 flights daily, with ultimate responsibility for the lives of almost 800 million passengers and crew every year. Professor Chris Johnson's research has directly influenced policy, legislation and regulation across Europe's air traffic control, including the current guidelines on software development in Air Traffic Management, which were incorporated into European law in 2008. He has led the way in harmonising computer infrastructure standards across different agencies throughout the EU, building defences against cyber-attacks and playing a vital role in improving passenger safety.
The World Health Organisation's (WHO) Surgical Safety Checklist is the culmination of over 5 years of concerted research effort to better understand, model and intervene in human factors that affect clinical performance and patient safety in operating theatres and surgical care. Imperial researchers were instrumental in the set up and implementation of the WHO `Safe Surgery Saves Lives' working group, launched in 2006, from which the Checklist was a primary outcome. Subsequently, we were co-investigators, and UK-lead, in a global study the implementation of the Checklist in 8 pilot hospitals across 7 continents. The Checklist was demonstrated to significantly improve patient outcomes and was modified and mandated for use in all NHS surgical procedures in England by the National Patient Safety Agency. We have since lead a national study that evaluated the implementation of the Checklist within the NHS and successfully delivered a team training programme aimed at optimising use of the Checklist in our hospitals.
This case study describes the international impact of research in the computer modelling and simulation of automotive and aerospace crashes, undertaken by Professor Blundell. The main impacts arising from the research can be summarised as:
Economic impact and impact on passenger safety: i) our research has led to improvements in the MADYMO software suite, the `industry standard' software for safety design and virtual crash testing, which is produced by TNO Automotive Safety Solutions (TASS) and sold to all the main equipment manufacturers in the automotive and aerospace sectors ii) our research has reduced the costs of these equipment manufacturers, who can simulate a crash rather than undertake expensive, physical, crash tests iii) by improving MADYMO, our research has had an impact on passengers who are now travelling in cars and aircraft which safer as a result of MADYNO's enhanced capabilities.
Impact on practitioners and professional services: through working with Blundell and his group, Autoflug GmbH has learned how to incorporate advanced simulation into its product development process. The work has also transferred practices from the automotive sector into aviation. Blundell's research has helped to introduce manufacturers and European regulators to new methods to design safety systems to helicopters, an area previously underdeveloped as an area in aviation occupant crash protection.
Beneficiaries include Autoflug GmbH, TASS and its customers, and European aviation regulators.
Research into variable mechanical energy absorption, using Finite Element (FE) modelling and analysis, funded by Cellbond Ltd., led to a design specification for an Offset Deformable Barrier (ODB). Such barriers are used within the motor manufacturing industry to test vehicular safety. Based on the findings of our research, the barrier used in car crash tests has been redesigned. The design specification for the barrier has been adopted by the European New Car Assessment Programme (EuroNCAP). All newly designed cars are tested with this type of barrier before they enter production. The use of FE modelling and virtual crash testing allows barriers to be designed with particular properties and for the crash testing cycle to be shortened.
(1) Enhancing the awareness of (i) women of childbearing age suffering from epilepsy and prescribed new and/or older generation AEDs, and (ii) their healthcare professionals. Empowering both to make informed decisions through evidence-based practice that will reduce/prevent the risk of harm to unborn children potentially exposed to AEDs in early pregnancy.
(2) A change in the process by which GlaxoSmithKline (GSK) practices post-marketing epidemiological surveillance of the new generation AED `lamotrigine' in pregnancy.
