Abstract
Critical care in the United Kingdom is now well-established in terms of professional status, standards of clinical practice and training, and national audit through professional bodies and government representation. Research is fundamental to the further development and maturation of the specialty, to develop new therapies and technologies, more efficient and effective service organisation, and to improve patient and family experience and outcomes. Critical care research has expanded rapidly in the UK, and now has established organisations and infrastructure to share and develop ideas, through the UK Critical Care Research Forum and similar meetings. In September 2014, the Intensive Care Foundation and Critical Care Leadership Forum hosted a research colloquium to reflect, in part, on achievements, but more importantly plan for the future. With an invited list of participants the meeting explored firstly – the practical delivery of clinical research and secondly – the future financing landscape, from both academic funders’ and commercial developers’ perspectives. The following article summarises the important ‘take home’ messages from this meeting and suggests key issues for future strategy.
Critical care in the United Kingdom is now well-established in terms of professional standing, clinical and training standards, and national audit through professional bodies and government representation. Research is fundamental to the further development and maturity of the specialty to develop new therapies and technologies, more efficient and effective service organisation, and to further improve patient and family experience and outcomes. Critical care research has expanded rapidly in the UK, and now has established organisations and infrastructure to share and develop ideas, through the UK Critical Care Research Forum and similar meetings, and to deliver large-scale practice-changing research through the NIHR Clinical Research Network (http://www.crn.nihr.ac.uk). The NIHR CRN national specialty group in Critical Care is widely-recognised as being very effective, enabling the effective delivery of a growing portfolio of clinical research studies. Success is visible through the publications resulting from the increasing numbers of high-quality large trials.
In September 2014, the Intensive Care Foundation and Critical Care Leadership Forum hosted a research colloquium to reflect on achievements, but more importantly plan for the future. A wide range of national research leaders, representing virtually all of the major government and charitable funders, attended and spoke. Senior members of the NIHR delivery network also contributed, along with leaders from industry and academic training programmes. These talks were complemented by presentations from members of the critical care community, reflecting on issues and opportunities specific to our specialty. The aim of this article is to report the key messages of these talks and discussions to the critical care community. We have used notes and discussions to summarise their impressions of the important ‘take home’ messages. We present suggested key learning points for moving forward.
What was said?
A summary of key points made by speakers from major external organizations who attended the meeting.
A number of other contributions were made from members of the critical care community. Professor Tim Walsh (National Lead of the NIHR CRN: Critical Care Specialty) reflected on the impact of the NIHR clinical research network on critical care during the first 6 years of its existence. Great progress has been made, with increased numbers of studies, progressively increasing engagement of ICUs with embedded research staff and infrastructure, and a coordinating specialty group-based organisational structure that is improving access to and efficiency of research. Challenges for the future include maintaining activity through project grants, developing commercial/industry research, and coordinating allocation of new projects according to capacity and likely patient base. A move towards wider use of extended hours of screening and recruitment, including weekends, would likely have a major impact on recruitment. Dr Tony Gordon (ICS Co-director of research) reviewed the potential benefits of large-scale international collaboration, and the need for large trials with sufficient statistical power to detect minimum clinically important differences in outcomes such as mortality. Given the heterogeneity of critical care populations, studies with power to detect important differences in a priori defined sub-groups is highly desirable. This is unlikely to be achieved within single countries, especially for specific types of critical care populations. Several projects have already explored the feasibility of international collaboration at different stages from planning through to post-funding participation. Success has been variable. Major challenges that have emerged include the timing and ability to satisfy multiple national funding bodies, and working to different timescales and review structures, potentially with differing research priorities. Sheila Harvey (CTU manager, ICNARC; www.icnarc.org) discussed recent experiences of optimising recruitment into critical care trials. She noted the importance of coordination and communication, and working closely with individual site teams and R&D departments. The NIHR network has offered significant benefits that can reduce the workload of trial management. The shared experience of the various trial units in recent years and multiple investigators with experience of setting up and delivering multicenter trials highlight the need to avoid ‘silos’ of expertise and to share knowledge and experience. At present we have no generic mechanism of sharing models of critical care research delivery, or core materials such as databases or questionnaires. Professor Gavin Perkins (Co-director of research, ICS) gave a brief overview of clinical trial activity and successes in the UK, highlighting the exponential growth in activity and key publications. Professor Danny McAuley (Co-director of research, ICS) highlighted the opportunities to develop and realise translational projects linking basic science discovery to clinical benefit. The NIHR schemes recognise this natural progression through its different Medical Research Council (MRC) and NIHR-funded schemes; the MRC contributes funding for the Efficacy and Mechanisms Evaluation programme, which acts as a bridge between basic and clinical research. However, the importance of only progressing to large and expensive phase III trials when both the science and the trial design are as fully worked out as possible is key to both success and value for money for funders. The history of negative trials in critical care highlights the importance of this issue. Dr Nazir Lone discussed the enormous potential for ‘big data’ to inform multiple aspects of knowledge about critical illness. In particular, these epidemiology approaches may enable better and more efficient trial design, for example through better stratification or adjustment, or for collecting longer term outcomes through data linkage methods. The need for high-quality research training in this area was clear.
Key messages
There were many messages for our specialty from this stimulating and collaborative meeting. The authors have attempted to refine these into some focused issues that may form the basis of future work, and serve to help prioritise where research effort should go. We have grouped these under several headings:
Clinical research question priorities
The community should develop research questions and submit these through the prioritisation schemes, with the aim of some projects being commissioned.
Research questions must have demonstrated clear importance to the NHS: this may include the views of patients, clinicians, and other stakeholders but must demonstrate clear potential for cost-effective improvements in care.
Research questions with global relevance that ‘stretch’ to the developing world are important to major funders (notably the Wellcome Trust)
Engage with major funders during research question development (especially the Wellcome Trust)
Research questions that involve or emerge from collaboration with Industry are a high priority: These could emerge at different developmental stages, ranging from pre-clinical basic science to early phase trials, and the design of phase III trials.
Infection and trauma are UK and global priorities relevant to critical care.
Types of research
Research using ‘big data’ is a priority: In the UK, the acquisition of uniform ICU-level data through national audits offers enormous potential to use ‘big data’ in research, especially if linked to other data sets that provide additional information about co-morbidity and longer term outcomes. Precision medicine approaches are needed for critical illness: The multiple sources of heterogeneity in critical care populations, including demographics, pre-illness morbidity, and acute illness type and severity could all contribute to variable effects, potentially in opposite directions, for similar interventions. Genetic variation could also influence these issues. In addition, the timing of an intervention may be important in a manner similar to the staging of cancer, but within a far more restricted time window. Better genotyping and phenotyping of critical illness is needed: This will improve research quality on multiple levels. For example, for precision medicine a better understanding of clinical phenotypes and genotype may improve the timing and choice of intervention; this might involve biomarkers, other diagnostics, and patient pre-illness or acute illness characteristics. For trial design better methods of selecting trial participants, stratification or minimisation at randomisation, or adjustment in relation to outcome comparison could all improve trial efficiency and quality. Research that involves or engages with the engineering and physical sciences is needed, for example using informatics to model ‘big data’, or novel technology for diagnostics: These collaborations have the potential to make major steps forward in understanding and treating disease. Breaking down academic silos to bring experience and knowledge together within and between institutions is needed. Methodology research is needed: For example, to improve trial/study efficiency or to enable clinical and cost-effectiveness to be detected within heterogeneous populations. International collaboration may be needed to achieve adequately powered studies: This requires work with funders to navigate simultaneous application, prioritization, and review processes. Translational research, especially with Pharma and Technology industries, is a priority and is currently underdeveloped: Drivers for this include the need for Industry to access clinical data and academic expertise, and also the potential to attract research funding and IP to the UK. Develop human models of disease processes wherever possible: The limited success of animal and cell-based work mean strategies to test novel therapeutics in human or ‘humanised’ models, for example isolated organs, healthy volunteers, or well-defined groups within ICU populations, should be considered at an early stage.
Academic Training
UK critical care needs a clear strategy to engage clinicians (medical, nursing and allied professional) in high-quality academic training.
Training schemes are needed in both basic sciences and health services research: the needs of each are quite different, health services research in particular needs strong methodology training. Strategies to support ‘run through’ training, especially post PhD, are needed: future senior academic posts are likely to require competitive fellowship funding (for example from NIHR, MRC, or Wellcome Trust) because Universities will appoint few tenured positions at Senior Lecturer or similar ‘entry level’. This will require strong support and flexibility within deaneries for the most promising academic trainees. A strategy to provide strong mentorship is needed: National coordination of access to mentorship is needed, especially given the relatively small size of the academic community.
Research delivery
Maintaining national coordination of the NIHR delivery network is a priority: Key priorities should be maintaining activity within research-active ICUs, and increasing access to research within these and non-research active ICUs. As study numbers fluctuate, careful planning is needed to ensure equitable access to research studies while managing the potentially detrimental effects of study competition. Research leadership within Local Clinical Research Network regions and within individual ICUs must be maintained: This will require pro-active approaches and engagement with local R&D and Local Clinical Research Network (LCRN) divisional managers. The role of the local Specialty group Lead is of high importance. Generic tools relevant to trial delivery should be shared: These might include unified core outcome datasets, and harmonisation of tools such as core daily ICU data, resource use questionnaires, or disability measures. Active sharing of expertise, especially for mentoring new and emerging investigators, should be undertaken. The UK critical care research forum (UKCCRF) should be further developed: The UKCCRF is the major stakeholder meeting for presenting, developing, and supporting new projects. This is a fundamentally different, but complementary, role to the NIHR CRN. To develop greater standing and effectiveness, analogous to well-known international groups (e.g. CCCTG; ANZICS trials group), this organization/grouping needs to be further developed. The critical care community should work pro-actively to deliver industry sponsored research: This is a high strategic priority for the NIHR and UK government. At present there is relatively little industry-sponsored work on the UK critical care research portfolio.
Conclusions
This is an exciting but challenging time for UK critical care. An enormous amount has been achieved in the development of the professional specialty, with research playing a major role. The reorganisation of UK research funding and delivery brought major benefits for our community but we are probably emerging from a ‘honeymoon period’ of success. The conclusions from the Stakeholder event provide a potential focus for future efforts and initiatives.
