Submitting data on performance in initiating and delivering clinical research

The NIHR collects data on initiating and delivering research from providers of NHS services in England that undertake clinical research, including trusts that undertake NIHR-funded research and those that deliver studies on the NIHR Clinical Research Network (CRN) Portfolio.

This is known as the Performance in Initiating and Delivering  Clinical Research (PID) exercise. Providers of NHS services are required to submit PID data to the NIHR every quarter.

Who needs to submit PID data

Providers of NHS services that hold an NIHR contract issued after Autumn 2011, for example from one of our research programmes or the CRN, are required to provide data to the PID exercise on recruitment to and delivery of all clinical trials, including commercial contract clinical trials.

Please note that, unless the organisation’s R&D Office has been contacted directly by the NIHR Central Commissioning Facility (CCF), the NHS provider does not need to submit any data to the PID exercise.

Find out who needs to submit data in our information submission guidelines.

Data requirements

NHS providers are required to submit information to the PID exercise in two areas:

  • initiating clinical research
  • delivering commercial contract clinical research to time and target.

The NIHR and the Health Research Authority (HRA) have collaboratively developed a single ‘minimum data set’ for clinical trial data, which reflects the HRA approval processes and CRN recruitment data terminology.

The revised data set simplifies reporting and provides greater flexibility for understanding performance at all points across the study lifecycle, at both a site and study level, without competing or duplicating metrics.

See the full list of data required for the PID exercise in our minimum data set table.

How to submit

Trusts are required to submit data online through the Clinical Trial Performance (CTP) submission platform.

Read our instructions on how to use the CTP submission platform.

If you have any questions regarding the PID exercise, contact the NIHR Clinical Trial Performance team on

When to submit

Information should be provided to the NIHR and published on the NHS provider’s website within 30 calendar days of the end of each quarter.

For the following four quarters, the submission timetable is as follows:

Quarter Period Start Date Period End Date Submission and Publication Deadline
Q1 2019/20 01 July 2018 30 June 2019 Tuesday 30 July 2019 5.00pm
Q2 2019/20 01 October 2018 30 September 2019 Wednesday 30 October 2019 5.00pm
Q3 2019/20 01 January 2019 31 December 2019 Thursday 30 January 2020 5.00pm
Q4 2019/20 01 April 2019 31 March 2020 Thursday 30 April 2020 5.00pm

Publishing data

The NIHR uses PID data to compare performance in the initiation of clinical research across NHS trusts and analyse trends. We publish this comparison data and trend data on our website.

The Department of Health and Social Care, via NIHR contracts with providers of NHS services, mandates the publication on a quarterly basis of information on clinical trial initiation and the recruitment to time and target for commercial contract clinical trials.
