Surgical Trainees

Information for Surgical Trainees

The Sunflower study – funded by the NIHR HTA – is the UK’s largest RCT investigating the management of patients with gallstone disease. It aims to compare the clinical and cost-effectiveness of expectant management and MRCP prior to laparoscopic cholecystectomy and will recruit 7,457* patients from more than 50 UK hospitals. The contributions of trainees are therefore vital, and we are very much looking forward to working with you!

*this target was reduced in an approved amendment in 2023
We have recently appointed two national lead trainees to join the study management group. If you are a trainee interested in taking part, please write to:
Lucy Scott,                          Hannah Byrne

Please also find here a Top Tips document that is great document to have at your site. It covers all sorts of key points around recruitment including flagging up new trainees to the study, hpw to advertise the study and how to explore different routes of recruitment e.g emergency and elective pathways.

Trainee benefits of being involved in the Sunflower study

Research logbook: We have worked hard to ensure that all of your efforts are recognised: screening and identifying eligible patients, recruitment consultations, collecting baseline or follow up data, and co-ordinating trainees’ efforts on a local or regional level. Much like an operative logbook, we will be able to provide you with a breakdown of your activities at regular intervals, to demonstrate your contributions for the purposes of ARCPs, interviews, portfolios etc.

CCT requirements: Participating in the Sunflower study will provide you with the opportunity to complete various CCT requirements, including: i) GCP training, ii) leadership role, iii) recruitment of patients to a national study, iv) research methods training. We will also provide you with training in how to best recruit patients into an RCT, see FAQs below.

NIHR Associate Principal Investigator (PI) Scheme

We fully endorse this exciting new scheme run by the NIHR. We aim to have two associate PIs in every recruiting centre.

The scheme helps junior doctors to be PIs of the future. It aims to engage, recognise and promote junior doctor engagement in NIHR portfolio research. It was developed by the West Midlands Research Collaborative, Birmingham Surgical Trials Consortium, Birmingham Clinical Trials Unit and the West Midlands NIHR Clinical Research Network.

The Associate PI scheme has been endorsed by the NIHR Clinical Research Network’s (CRN) Cancer, Surgery and Oral & Dental Specialty Cluster and the Royal College of Surgeons (England).

There can be two Associate PI per site, per study, at any given time. A commitment of at least 6 months will be required for gaining Associate PI status, after which the NIHR CRN will issue a certificate to confirm Associate PI status.

The study has been given special permission to have a radiology Associate PI alongside the surgical API.
Mr. Jonathan Rees, PI at University Hospitals Bristol, outlined the benefits:
“Having a radiology API has given us a link to the team who provides our key investigation in the trial i.e. MRCP. It has been exceedingly informative exploring MRCP requesting and the relationship between the quality of information provided and the likelihood of finding a bile duct stone. These findings have helped us develop a strategy for the MRI scanner team to decline or accept requests for MRCP and also flag patients to the Sunflower study with auto- reporting with text that says – refer to Sunflower study.”

Please email if you would like to be considered for this prestigious role. If you have any queries about the scheme, you can contact or find further information on the scheme at the NIHR website.
