We offer safe, secure access to patient data and provide one-to-one support to help your trial run smoothly and efficiently. Our services can support you at every stage of the clinical trial process. 

What NHS DigiTrials does

Our services support clinical trials by
  • advising on the depth and breadth of available datasets

  • offering safe, secure access to patient data collected by the NHS in England

  • providing one-to-one support at every stage of your trial, helping your research run smoothly

  • guiding you through the process and requirements for your data application

  • working with patients to design and evolve our services to reach every community

Our research has shown that many people are keen to take part in trials - both for the chance to try new treatments, and to help others.

Feasibility Service

What we do

When you are at the planning stage of your trial, our Feasibility Service can help you establish how many people might meet your eligibility criteria.

The service can also support you in determining suitable locations for your trial, by establishing where the largest groupings of eligible people are based. 

Our Feasibility Service can be accessed in two ways: 

1. Feasibility Self-Service (in public beta)

We have developed a self-service tool where you can run your own searches in real-time and export your results in a secure Data Access Environment (DAE). The DAE provides secure access to the health and care data we hold and reduces the need for it to leave NHS England.

The source data assets used currently are: 

  • Personal Demographics Service (updated daily)
  • Hospital Episode Statistics (HES) - Admitted Patient Care (updated monthly) 
  • Hospital Episode Statistics (HES) – Outpatient (updated monthly)
  • Medicines dispensed in primary care (updated monthly) 

We provide guidance on how to access and use this service.

2. Managed Feasibility Service

For more specific or detailed data needs, we offer a tailored service. Our case officers will work with you to unpack your needs and help you locate the data you require.

How it works

Our Feasibility Service runs searches of data that is routinely collected by the NHS in England and held by NHS England. This national data from a range of healthcare settings can help your trial reach communities across England. 

The searches are aggregated and small numbers are suppressed so individuals cannot be identified. This means the application process for using our Feasibility Service is less complex than for other data access requests.

The searches show how many people meet your trial's eligibility criteria, and where they are located.

How to apply

You need to download and fill in our Feasibility Request Form, which asks for more information about your trial.

The form can be used to apply for either Feasibility Self-Service or our Managed Feasibility Service. The form takes you to the section you need to complete for your required service.

Email your completed form to: [email protected] and enter 'NHS DigiTrials Feasibility Service' in the subject line.

Recruitment Service

What we do

We can support your trial through the process of locating and contacting people who are eligible to take part in your research. The aim of this service is to smoothly and efficiently recruit trial participants.

How it works

Our Recruitment Service can only help trials that would be eligible to receive Section 251 support under the NHS Act 2006, which allows a temporary lifting of the Common Law Duty of Confidentiality. 

Find out more about Section 251 on the Confidentiality Advisory Group (CAG) website

We can work with you to guide you through the Section 251 application process.

Our knowledge and expertise can ensure your application proceeds as smoothly as possible, from establishing if a trial might be eligible for Section 251 through to submission of your application and support being granted.

Our Recruitment Service is currently in the pilot phase, supporting a limited number of trials.

We intend to roll out the service to more organisations in 2023. Please email us to let us know if you might like to partner with us in the future.

Recruiting volunteers to take part in revolutionary new cancer test

In just over 10 months, the NHS DigiTrials team recruited 140,000 participants for the NHS-Galleri trial, which aims to detect early signs of cancer using a blood test.

The trial was seeking people aged 50 to 77 who had not been diagnosed with, or treated for, cancer in the past 3 years.

We also needed to invite volunteers whose ethnicity, locality, gender and socio-economic circumstances aligned with the risk factors associated with developing cancer.

We started our campaign in September 2021 and full recruitment was achieved in July 2022. 

Applying for identifiable data

We have prepared some step-by-step guidance on applying for identifiable data.


Communication Service

What we do

Keeping participants informed about a trial is an important part of the end-to-end process, providing they have consented to receiving updates. 

Our Communication Service enhances how information is shared between clinical triallists and trial participants, both during and after clinical trials. 

We can support with the efficient distribution of communications such as newsletters, study outcomes and surveys by post. We intend to enhance our service to include more communication channels in the future. 

We use national data to ensure communications are only sent to trial participants who have given consent to receive the information.

The data can also identify if participants have moved house, passed away or withdrawn consent, so communications can be adapted appropriately.

How it works

Under the Data Sharing Agreement and Data Processing Agreement between your trial's organisation and NHS England, we are able to identify the contact address for people who have signed up to a trial and consented to receive information about the research. 

We are able to automatically check a trial participant's most up-to-date address. Our check also shows if any participants have passed away, so their details can be removed from mailing lists to minimise distress to family members.  

This information is securely shared with our approved mailing providers, who send out the communication to the trial participants.

It means that the communications element of your trial can be managed centrally, which is particularly useful for multi-centre trials. Our service also takes the pressure of managing participant communications away from front-line research colleagues.

Outcomes Service

What we do

Our Outcomes Service can help you follow the progress of your trial participants. 

This service provides national, routinely collected datasets from a range of healthcare settings.

These datasets will help you efficiently explore and assess the outcomes of your trial treatments.

How it works

Our Outcomes Service helps you follow up your participants by requesting their data from NHS England, providing your trial has the necessary legal basis.

Under a Data Sharing Agreement and Data Processing Agreement between your trial's organisation and NHS England, you will securely share with us a list of trial participants.

The list ls usually made up of people who have consented to:

  • their identifiable data being linked to our national datasets
  • relevant data being extracted according to the needs of your trial

We can help you to establish if you have the correct legal basis to do this. This linked data will then be made available to your team to securely retrieve for analysis.
