Please note this framework has now been replaced with the managing research recovery process.

A framework for restarting NIHR research activities which have been paused due to COVID-19 

Purpose of this paper

The purpose of this paper is to set out a framework to guide the restarting of NIHR research activities which have been paused due to COVID-19. 

The term ‘NIHR research’ refers to research either funded or supported by NIHR in healthcare, social care and public health settings. 

The key aims of the framework are to guide:

  1. the restart of paused NIHR research that was underway in the health and care system prior to the COVID-19 ‘surge’,
  2. the commencement of ‘new’ NIHR research, and 
  3. the prioritisation of resources in the NIHR Clinical Research Network (CRN) and NIHR infrastructure more broadly. 

The framework sets out guiding principles, preconditions, study prioritisation, and local and national roles in implementing this ‘Restart Framework’.


The emergence of the COVID-19 pandemic in early 2020 led the NHS to suspend many routine clinical services and the NIHR to prepare to support the Government’s research response. Subsequently, the decisions taken in March 2020 by research sponsors, funders, investigators and study sites to pause some non-COVID-19 research, and by the NIHR Clinical Research Network to pause set up of new sites or studies, other than for nationally prioritised COVID-19 studies, led to a rapid and significant reduction in NIHR research activity. 

Towards the end of April 2020, there were indications that the pressures on the UK health system were easing in respect of COVID-19, and therefore that paused and new NIHR research might gradually resume. These indications included a steadily falling hospital admission rate for COVID-19, the suspension of some ‘surge’ capacity in the NHS, and the 29 April 2020 letter from the CEO of NHS England and NHS Improvement (“Second phase of response to COVID-19”) asking for a restart of non-COVID-19 urgent services and potentially some routine elective care.  Data from NIHR Local Clinical Research Networks (LCRNs) and NIHR Clinical Research Facilities (CRFs) further indicated that NIHR-funded staff that had been deployed to the clinical ‘front line’ were beginning to return to research roles. 

Consequently, a group representing NIHR Coordinating Centres initiated the development, involving multiple stakeholders, of a framework for restarting paused NIHR research studies and restarting the NIHR Clinical Research Network support to set up new sites and studies.

This framework has been developed with specific reference to the position in England, in cooperation with Devolved Administrations who may produce aligned, but Devolved Administration specific, guidance.

Strategic objectives of ‘Restart’

  1. Restore a fully active portfolio of NIHR research to improve the health and wealth of the nation.

  2. Continue to support COVID-19 NIHR research as part of the Government response to tackle the pandemic.

  3. Provide a structure to guide the restarting of a full range of NIHR research, across all sectors of health, social care and public health, while maintaining local decision-making and flexibility.

  4. Work in close collaboration with key stakeholders, regulators, HRAMHRA, patients and the public, and health and care research organisations to support the pace and coordination of this Restart and to ensure coordinated UK-wide working.

Guiding principles

These principles have guided the content of the Restart Framework:

  1. The framework is intended to support the NIHR in recommencing research activities. It is recognised that guidance will need to be reviewed and refreshed, for example, in the context of learnt experience of restart progress and changes in COVID-19 activity.

  2. The framework is also intended to enable strong local leadership and decision-making in pursuance of proportionate and pragmatic arrangements.

  3. The priority is to restore an open and flourishing clinical research system whilst recognising that the impact of COVID-19, complexity of restart and many other factors will affect the future shape of the portfolio.

  4. In the initial period of Restart, achieving an optimal and national restart/start of research is a higher priority than attaining all the traditional metrics of research performance. 

  5. Patients and the public can play vital roles at both local and national level in supporting restart activities.

  6. COVID-19 related research will form a significant and high-profile component of the NIHR portfolio for the foreseeable future and COVID-19 Urgent Public Health Research studies will continue to be prioritised. Any further surges in COVID-19 could affect the research system again and the potential for a 're-pause' must be considered by sponsors, funders, Chief Investigators and local sites in the plans to restart individual studies.  

  7. The decision on whether to restart a paused study, or commence a new study, rests with the study sponsor, funder, Chief Investigator and the study site(s) legal entity.

  8. The pace of the restart will be influenced by preconditions that must be met prior to restarting research (see 'Preconditions for restarting/starting research') and because prioritisation may be necessary (see 'Prioritisation').

  9. There is likely to be variable and rapidly-changing levels of research capacity in differing geographical regions, sites and departments.

  10. The framework also recognises variability in the capacity in universities to support clinical research processes (e.g. sponsor roles, laboratory facilities), emphasising the importance of close working with partner NHS trusts.

  11. Some sites may wish to restart/start a small number of studies in a pilot to quickly gain experience and learning which will help optimise further restart/start processes. 

  12. The NIHR is well-placed to provide guidance, support, communication, liaison with taskforces (e.g. vaccines, therapeutics) and collaboration at local and national levels.

Preconditions for restarting/starting research

The restart of a currently paused study and the start-up of new studies will be dependent on a number of preconditions being met. It is the responsibility of the sponsor, funder, Chief Investigator, the study site(s) legal entity, and, where applicable, the Principal Investigator at each site to assess that these are met before restarting/starting.

There are therefore important roles at local sites and at national level (see sections 'Local level roles' and 'National level roles'). At local sites, the framework suggests an Assessment and Prioritisation panel is established, ideally led by the R&D Director, supported by clinical investigators, R&D team and able to work with sponsors. Sites hosting non-CRN NIHR infrastructure will likely wish to integrate them into their local governance and accountability structures. The NIHR CRN, through the Local Clinical Research Networks, may be able to offer some support alongside the local R&D team, especially to trusts in which there is not an identified R&D Director. Similarly, Local Clinical Research Networks may be well placed to support primary care sites in their region.

Study viability 

Principle: Only research that is still viable should restart/start.

Some studies that have been paused or have not yet started may no longer be viable, for scientific, clinical, financial or practical reasons. It would be unethical and a waste of money to restart/start studies that are no longer viable.

Therefore, at the earliest opportunity, every paused study should undergo a check of its viability before restarting. This reassessment is a responsibility of the sponsor, working with the Chief Investigator, and funder (see sections 'Local level roles' and 'National level roles'). Sponsors and sites will be expected to work together to conduct a preliminary assessment of all paused studies ideally within one month of this framework being issued. At site level, the Assessment and Prioritisation panel would undertake this task. Where this assessment identifies viability issues that require resolution (e.g. funding, changes in resourcing requirements), it is not expected that these issues would necessarily be resolved within the one month period.

For some studies, viability will depend on redesign / protocol amendment. The sponsor / Chief Investigator should confirm that regulatory checks (if needed) and discussions with the funder to accommodate any such amendment have been agreed as part of viability checks. Independent Data and Safety Monitoring Committees, Trial Steering Committees and Clinical Trials Units (where applicable) should advise as appropriate.

Discussion of the optimisation of research processes, though extremely important, is out-of-scope of this framework but it is recommended that in assessing the study viability, the sponsor/Chief Investigator and funder take the opportunity to consider any potential key improvements that might assist restart and completion of the study.

The HRA and MHRA have developed (and frequently update) advice on measures to optimise regulatory processes in anticipation of and in response to COVID-19 and its effects on research. These regulators can advise on flexibilities that may be available.

This framework recognises studies as valid for restart if their funders support any study extensions and/or amendments necessary, and have confirmed a commitment to fund accordingly. This will allow those studies to begin preparations for restart, whilst giving research funders time to allocate the funds necessary to finance the study’s extension/amendment.

Any required changes to Excess Treatment Costs, where they are relevant, must also be identified and documented before restart.

Viability of NIHR CRN Portfolio studies: NIHR will, on request, offer the input and assistance of NIHR CRN National Specialty Leads and NIHR Programme Directors, and their group / committee members to assist in the assessment of study viability.

Viability of NIHR-funded studies: NIHR Programme Directors will review studies where amendments are proposed in each programme portfolio in line with established processes.

Viability of NIHR Infrastructure supported studies: NIHR Infrastructure Directors, in line with their local governance and accountability arrangements, will review studies where amendments are proposed in each programme portfolio in line with established processes.


Principle: Research should only restart/start when safe to do so.

Safety of research participants and personnel is of paramount importance.

Safety considerations in restarting research include:

  • Risk of exposure to COVID-19 (and measures to mitigate this).

  • Government guidance on social distancing, restart of work, and travel. 

  • Local site policies in respect of COVID-19.

  • People considered ‘clinically extremely vulnerable’ who are ‘shielded’ and who have participated in a paused study or are considered for a new study require special considerations. Their GP and/or specialist should be consulted to ensure they continue to receive the appropriate care with only essential visits to the research site.

  • An assessment of the need for patient testing for COVID-19 and requirements for personal protective equipment (PPE); these requirements may be specified in research protocol/procedures, otherwise local site policies should be used. 

  • Site compliance with protocol and regulatory requirements (e.g. compliance with clinical trials regulations and other relevant legislation and guidance).

  • Protocol amendments to reduce risk (generally not formal substantial amendments).

  • Participants’ concerns about COVID-19; participants need to feel safe and reassured about the research process.

  • Provision of clear guidance on safety issues and measures for participants and staff.

  • Assessment of requirement, processes and safety for study monitors/visits/meetings, and consideration of remote working where possible.

  • That any mitigations or flexibilities put in place to restart a study do not have an adverse impact on participant safety (e.g. reducing clinic visits).

Capacity and site readiness

Principle: The pace of restart and the commencement of new studies should be commensurate with capacity and readiness in local health and care services and the NIHR.

Delivery of research will be dependent on relevant health and care services being ‘open for business’. Capacity is likely to be variably reduced by several factors - type of facility (e.g. acute trusts and care homes often severely impacted by COVID-19), additional ongoing commitment to COVID-19 studies, additional measures required to ensure staff/patient safety, variation in restoration of NHS services and region – and all of which will vary geographically across England and change over time.

Preconditions include:

  • Availability / capacity of health and care study leadership and research / delivery / support staff
  • Capacity of the health and care site / service to undertake research
  • Capacity of the necessary research management infrastructure (e.g. R&D offices in health and care organisations, Clinical Trials Units, NIHR Coordinating Centres, LCRNs, Clinical Research Facilities)
  • Supporting departments, e.g. pharmacy, pathology, radiology have resource and capacity to resume
  • Physical access arrangements for participants, in light of social distancing, reduced public transport, and reduction in support from third sector organisations or third parties
  • Clear and explicit confirmation to restart research from the sponsor, and funder where relevant, and reconfirmation of capacity and capability by the site legal entity


If the preconditions for restarting a paused study, or starting a new study, have been met and there is no requirement for NIHR-funded support, the study may be ready to proceed. However, resource, capacity or other constraints may necessitate prioritisation of NIHR-funded support, including the workforce in NIHR CRN and NIHR CRFs.

Where prioritisation is necessary, this should be on the basis of ‘study urgency’, that is, how urgent the study is in the context of the health/care of the participant and the national priorities for health and care research. The framework indicates that prioritisation is irrespective of the type of funder or sponsor; all research funders and sponsors are essential to the improvement of health and care. Prioritisation does not imply that one study is ‘better’ or ‘more important’ than another but does reflect the urgency with which it should be supported. Discussions on prioritisation should be handled carefully, with consideration of any adverse perceptions, especially for study participants.

Three levels for prioritisation of NIHR CRN support should be applied according to study urgency (Level 1 is highest priority/urgency).

Level 1: Essential studies providing evidence for pandemic management, i.e. nationally prioritised COVID-19 Urgent Public Health (UPH) Research studies.

Level 2: Studies where the research protocol includes an urgent treatment or intervention without which patients could come to harm. These might be studies that provide access to potentially life preserving or life-extending treatment not otherwise available to the patient.

Level 3: All other studies (including new COVID-19 studies not in Level 1). 

We expect that directors of other NIHR infrastructure undertaking research not on the NIHR CRN portfolio will work their local Assessment and Prioritisation panel and that the principle of prioritisation in this framework will apply, in alignment with their host organisation's processes.

Notes on Study Urgency:

  1. It should be noted that in its first statement on the impact of COVID-19 on research (issued 16 March 2020), NIHR stated explicitly that “clinical trials or other research studies which are funded or supported by NIHR should continue if discontinuing them will have significant detrimental effects on the ongoing care of individual participants involved in those studies”. 

  2. Where guidance on prioritisation is provided it will be in the context of supporting studies when resource/capacity is constrained. 

  3. Even when prioritisation is required, sites may still have capacity for some studies that do not compete for resources or support. In these situations, proportionate and pragmatic, local decision-making, led by local Assessment and Prioritisation panels, can enable such research to restart/start (assuming the preconditions listed earlier in this framework have been met).

  4. COVID-19 studies that are not nationally prioritised (i.e. are not in the COVID-19 UPH Research group - Level 1) will be eligible to join the CRN portfolio (if they meet the normal CRN portfolio criteria) and will have equal priority with other ‘Level 3’ non-COVID-19 studies.

  5. It is likely that, over time, changes in COVID-19 activity, new research priorities and other factors may require revision to the prioritisation of studies. Any changes to the prioritisation schema will be managed through the Restart Implementation Group (see section 'National level roles'), in close consultation with the Restart Advisory Group (see section 'National level roles'), before being published and made clear to all stakeholders in an updated version of this Framework. 

  6. This prioritisation guidance is provided to cover the majority of scenarios but, by exception, other factors may need to be taken into account. The NIHR Restart Implementation group may be able to advise in such cases.

  7. The framework does not specify the balance between non-commercial and commercial studies or the complexity or phase of studies that restart/start. Where prioritisation is necessary (see 'Prioritisation'), it should be based on the urgency of the study to the welfare of the patient in the context of national priorities (e.g. Urgent Public Health). The NIHR Restart Implementation group will monitor this balance and offer guidance or direction as necessary.

Phasing and timescales

The NIHR wishes to restart paused and new research as soon as possible, and to support the energetic restoration of a fully active portfolio of NIHR research. The NIHR Restart Implementation Group will monitor the progress and pace of Restart.

In light of the fluidity of the COVID-19 situation and the variable levels of capacity and readiness for non-COVID research across health and care services we do not, beyond setting a one month period for sites to complete preliminary restart assessments, propose a ‘timetable’ or any fixed phasing for the completion of Restart. The pace of restart of paused studies and commencement of new studies will be dependent on the preconditions set out in section 5 of this paper being met on a case-by-case basis.
