Hello,
my name is Dr Caroline Thomas and alongside my role as a Consultant Anaesthetist in Leeds, I also chose to take on two dedicated leadership roles to drive health and care research locally and in our wider region.
Research is important to me. I see the value it has to the patient, to the system, and to people who champion its importance. Research helps improve care and helps make the best use of public spending. It opens up opportunities for patients to join clinical trials which can advance treatment and promote access to innovations.
My research journey started when I was undertaking postgraduate training in anaesthesia. After I was appointed as a substantive consultant in Leeds in 2017, I had the opportunity to be involved in research across the Yorkshire and Humber region and since then, alongside our research delivery team, I have worked on successful, high-quality NIHR portfolio research studies. My experience of working in research leadership and delivery roles locally, regionally and nationally has allowed me to spot gaps and opportunities for patient involvement and staff development.
One of my proudest local research achievements has been my involvement with setting up a dedicated research delivery team in theatres and anaesthesia in LTHT. Dedicated research delivery roles and integrating research opportunities into everyday care has promoted research involvement for patients we care for.
In Yorkshire and the Humber, the NIHR is very effective in recruiting a network for research participants, with over 106,000 people recruited during 2025-2026 to 1,123 NIHR Research Delivery Network portfolio studies. Our prominent delivery organisations play a vital role in promoting inclusive research. We have research-active organisations right across our region - across hospitals, primary care, community and residential settings.
Although hospitals remain the biggest recruiting research delivery sites, we are delivering the government's mission to promote health and care services research in non-hospital settings. By making health services and research opportunities available in GP practices, pharmacies, dental practices, community centres, hospices, prisons and more, this enables research to be accessible for all, and now 16% of research happens beyond hospital settings.
As a regional network we deliver research which saves and changes lives. Behind this is a whole infrastructure of key roles and governance processes to ensure accurate and well-governed research. One of many crucial roles in research set up and delivery is the appointment of a study 'Principal Investigator (PI)'. During my time as a consultant clinician and with the NIHR, I have taken on the role of PI for 14 studies and I have supervised 12 resident doctors completing the NIHR Associate Principal Investigator scheme. PI activity is a vital part of the running of studies and alongside other members of the research delivery team. PIs ensure that studies progress and meet their timescales and recruitment targets.
Thank you to everyone involved in all aspects of research right across our wonderful regional network and all the work you do each day to improve care for people in our services and communities.
