For participants

The BSRBR-RA is one of the largest studies in the world looking at the long-term safety of new drugs prescribed for rheumatoid arthritis in the real world. It has been capturing data since 2001 and we have now registered over 20,000 participants in the study.

We are different from a clinical trial, as we do not influence the treatment participants receive, but rather watch what happens when participants take the treatment that is prescribed by consultant rheumatologists.

Although these treatments are fully licensed and prescribed by the NHS, there is still a need to monitor their impact in the long term, which is the main role of the BSRBR-RA.

What is involved in being part of the BSRBR-RA?

Currently, data is collected from participants via questionnaires every six months for three years, and information on drug changes, hospital admissions and referrals is collected in a study 'diary'.

Questionnaires are sent in the post when they are due. If you have received a reminder to complete one of our questionnaires, you can download a blank copy of the baseline form or the follow-up form to post back to the study offices. If you are returning a follow-up questionnaire, please also include a diary (see above) for the same period.

Information is also collected via the participant's consultant for the duration of the study. The current end date is 30 September 2028.

Why get involved?

Getting consent

By participating, you will help us build up the amount of data we have for analysis. With more data, we will be able to reach better-informed conclusions on the long-term safety of the biologic treatments.

If you are not involved in the study but would like to be, please speak with your rheumatology team to see if you are eligible to join.

If you are already involved in the study and have some further questions, please contact the team at

You may find the patient information sheet (PDF, 159KB) useful if you would like to find out more about what participating in BSRBR-RA involves.

How is the study progressing?

Please see our latest patient newsletter for news and updates.

The data that is sent to us by the patients and consultants is analysed by the research team, who write up their findings, which are then published in research journals. You can read a summary of what has been found out so far in a journal article, The BSRBR-RA at 15 years by Hyrich et al.
