COHORT MULTIPLE RANDOMISED TRIALS A plan to address the research priorities identified by the James Lind Alliance Priority Setting Partnership in Adult Cardiac Surgery. Funded by In partnership with SCTS Society for Cardiothoracic Surgery in Great Britain and Ireland UNIVERSITY OF LEICESTER UNIVERSITY OF LEICESTER FOREWORD UK cardiovascular research is world leading in terms of quality and impact. This is attributable to our unique NIHR research infrastructure and funding that makes the NHS the best environment in the world to undertake clinical research, combined with over £100m per year from the British Heart Foundation, the world’s largest funder of research into cardiovascular disease. Cardiac surgery in the UK has the capacity to deliver world class clinical research, and has produced many pivotal trials over the last 5-10 years. However, as a specialty, cardiac surgery is undergoing a period of transition, with increasingly elderly and frail patients referred for surgery, and the continuous development of new less invasive techniques and devices. Continuing to deliver the best personalised care to patients in these circumstances requires high quality evidence based on research. The research environment is also changing; clinical research is now undertaken by interdisciplinary teams of professionals with diverse skills. Important questions are also often best addressed by national and international networks of researchers. Patients and the public must also be central to all our research activities. This report describes an approach to cardiac surgery research that will address the changing environment, capitalise on our unique research infrastructure, and result in the best care for our patients. First, we will focus our endeavours on the questions that matter most to patients and clinicians. Patients must be at the centre of our research, and continue as partners and advocates through the lifetime of the research programme. Second, we will come together as a specialty to undertake high quality research in every UK cardiac centre. This research must be interdisciplinary and of the highest quality. Third, we must develop a cohort of young researchers, both trainee surgeons as well as nurses and allied health professionals, who will emerge as research leaders within the next decade. Finally we must create lean, pragmatic research platforms that are attractive to industry partners to enable accelerated technology transfer and device evaluation, as these represent the future of our specialty. This report we hope will form the basis for a conversation that will enable all stakeholders to contribute to the process, and ensure that we can translate CONTENTS our research priorities into a research programme that will lead to better care for patients. 3 FOREWORD 4 A NATIONAL CLINICAL TRIALS PROGRAMME IN ADULT CARDIAC SURGERY 5 PROJECT MILESTONES 6 THE TOP TEN PRIORITIES FOR ADULT CARDIAC SURGERY RESEARCH 8 ADDRESSING RESEARCH PRIORITIES USING A COHORT MULTIPLE RCT DESIGN Professor Gavin Murphy, BHF Chair of Cardiac Surgery 12 FORMULATING RESEARCH QUESTIONS 16 BIBLIOGRAPHY 17 NEXT STEPS 18 ACKNOWLEDGEMENTS AND DISCLAIMER 2 3 UNIVERSITY OF LEICESTER A NATIONAL CLINICAL PROJECT TRIALS PROGRAMME IN MILESTONES ADULT CARDIAC SURGERY RATIONALE IMPLEMENTATION THE NEXT 10 YEARS Patients undergoing cardiac surgery in the Infrastructure: In 2017, the BHF The UK presents a unique environment for United Kingdom benefit from the highest established a clinical trials funding clinical research and innovation in cardiac quality care.
