In the NHS, we are very careful to make sure that researchers who want to work with our patients are carrying out safe, ethical, well considered research. It is important to make sure that patients’ rights and well-being are considered, and that research is in their best interests.

We have to make sure that the benefit of the research outweighs any harm or inconvenience. If the research is not planned or thought-through properly, then it may be that the findings are not useable. This would mean that everyone involved will have wasted their time and money. Any study that comes to your GP or other NHS site will have been checked, and special checks are in place if the research involves radiation, genetic material, human tissues, children, embryos or prisoners.

Some studies are funded by drug companies or companies which manufacture medical devices. These go through the same checks as any other study, to make sure that the research is asking a valuable question and is properly conducted – not just in the interest of the company.

It is important for new drugs and devices to be tested, first and foremost so that we know if they are safe, but also so that we know if there are any issues with using them (for example side effects or if patients in a real-life setting find them too difficult or unpleasant to use). All of these trials are very strictly regulated. But they are also important as they are necessary for new treatments to be developed. A drug or device goes through a lot of checks and processes before it comes to patient testing.

If patients are asked to take part in a research study (and they should always be asked, not forced or coerced), they should be given information about the study (including any risks), should have the opportunity to ask any questions, and will give their consent to take part. For people who cannot consent (children, some vulnerable adults, people who are unconscious) there have to be special arrangements to make sure their rights are protected. If someone cannot give written consent (e.g. If they cannot read or write) there must be a suitable alternative. These are all things an ethics committee will look for when agreeing for a study to take place. This can also be checked at any time if a study is audited. A patient can change their mind and withdraw their consent if they want to.

These checks also make sure that the people who are undertaking the research are properly qualified and trained.

What questions do we ask?

Before a study starts in the NHS, it will have been through a process:

This process ensures the study has been checked by a number of sources before it takes place, and when a patient gets involved he or she can be confident that the study has considered all the relevant issues. If you are approached to get involved in research and are concerned about safety or any element of the study, there should always be a contact within the study who should be able to address any questions or concerns. You can also contact us if you are concerned about a study.

How do I know my data is safe?

You can read more about how your data is handled in research by visiting the Health Research Authority website:

You have the choice to decide whether your data can be used for research. We call this the ‘opt-out’ process. NHS Digital has a page dedicated to the national data opt-out and mythbusting:
