NIHR CRN Portfolio

The NIHR Clinical Research Network (CRN) Portfolio is the group of high-quality clinical research studies that have satisfied certain eligibility criteria. The NIHR CRN Portfolio is part of the UK Clinical Research Network Portfolio. Important things to remember about the NIHR CRN Portfolio:

  • If you want to submit your research project for adoption to the Portfolio, please check ‘yes’ to either question 5a or 5b in the IRAS form project filter and complete and submit the IRAS Portfolio Adoption Form (PAF).
  • Non-commercial studies that have been adopted on the Portfolio are eligible for consideration for service support costs from the Clinical Research Network in England through CLRN contingency funding.
  • Portfolio studies are registered on the UK CRN Portfolio database and monthly recruitment data must be uploaded. The recruitment data informs the allocation of NHS infrastructure for research (including NHS Support Costs)

More information about the Portfolio, including details of eligibility and benefits of inclusion, can be found at the NIHR’s website.
