Clinical research informs the guidelines and recommendations that underpin delivery of clinical care.

Undertaking research is a priority for a trust constantly seeking to improve and develop patient care.

Clinical research paramedic

The research team in SCAS is responsible for overseeing all clinical research projects undertaken by the Trust. We are a small team, and we have been involved in large scale research trials including PARAMEDIC (the Prehospital Randomised Assessment of a Mechanical Device In Cardiac arrest). SCAS was one of four ambulance trusts which took part in this national study, which received the prestigious accolade of ‘Trial of the Year 2014’ awarded by The Society for Clinical Trials.

We have strong links with our neighbouring acute trusts through the local research network and with the other UK ambulance services via national networks. This enables us to hear about the latest research projects and get involved from the early stages.

VAN Study


SCAS started a small pilot study of this trial in February 2015, followed by wider implementation in August 2015. The last patient was enrolled in October 2017 and no more patients will now be included. SCAS ambulance staff now provide standard care to patients suffering cardiac arrest. Trial results are expected to be published in the latter half of 2018. This trial, led by the University of Warwick, aimed to improve the outcome for patients suffering cardiac arrest (when the heart stops beating) outside of the hospital environment. Of the 30,000 people experiencing this catastrophic event each year, no more than 7% survive to hospital discharge. Although the drug “adrenaline” has been used as part of the standard treatment of cardiac arrest since the 1950s, there have never been any trials to show whether it is of benefit or not.

This trial looked at whether adrenaline, which can be administered during resuscitation, improved a person’s chance of survival to hospital discharge. It had been assumed that by stimulating the heart, adrenaline may improve the chances of successful resuscitation. However, some recent studies have suggested that although adrenaline may indeed help ‘restart’ the heart, the chances of survival in patients given adrenaline may actually be worse. This may be because when adrenaline stimulates the heart it increases the amount of oxygen required by the heart which may, in turn, reduce the amount of oxygen available to the brain.

How the trial worked

The International Liaison Committee on Resuscitation, European Resuscitation Council and Resuscitation Council (UK) which all set the current resuscitation guidelines, identified the urgent need for a clinical trial to look at whether current adrenaline therapy is safe and effective. The only way to do this is by a type of research study called a randomised trial comparing adrenaline with a placebo (saline), in which neither the clinician nor the patient is aware of the group into which they have been randomised. Adult patients who suffer cardiac arrest, and where advanced life support is given, were eligible for the study. Those who were pregnant, suffering from anaphylaxis or where adrenaline had been given prior to ambulance arrival were not enrolled in the trial. At a cardiac arrest where adrenaline is indicated, clinicians were supplied with a pack of trial medicines, which were used in place of standard adrenaline syringes. Patients have been followed up in hospital and the study investigators will compare what happens to the two groups of patients (those who received adrenaline and those who received placebo).


Members of the public who did not wish to be enrolled in the PARAMEDIC2 Trial could choose to opt-out by requesting a stainless steel bracelet which has the words ‘NO STUDY’ engraved on it. Local paramedics were trained to look for these bracelets in the same way they do for other medical ID bands. This meant that, in the event that you have a cardiac arrest, you received standard treatment which may have included adrenaline. This system is used successfully in North America for a number of trials.

Further information

The trial, funded by the National Institute for Health Research by the University of Warwick in collaboration with the University of Surrey, received Research Ethics Committee approval and Medicines & Healthcare products Regulatory Authority (MHRA) approval. It involved five ambulance trusts (South Central Ambulance Service, London Ambulance Service, West Midlands Ambulance Service, Welsh Ambulance Service and North East Ambulance Service) and aimed to recruit a total of 8,000 patients: the number needed to be sure that any benefit or harm from adrenaline can be detected. The data was analysed at stages as the trial progressed so that had a difference been detected sooner, the trial could be stopped. It is usual practice to obtain informed consent from patients to participate in research studies. Inevitably, there are ethical challenges and concerns involved in a trial where patients are unconscious and cannot give their agreement to take part. This has been a concern for researchers working in the pre-hospital setting for some time and has recently been highlighted in the press. It has been suggested that if patients are unable to give consent, either because they are in an emergency situation or are unconscious, they should not be included in a research trial. However, this would severely reduce the opportunities for improving the care of patients suffering conditions such as cardiac arrest.

A number of years ago this was debated at the highest level in the UK Government and the European Union. A new law was drawn up that allowed researchers in specific emergency situations to enrol patients in a study without obtaining consent (waiver of consent) so long as consent was obtained as soon as reasonably possible after the patient was able to make a decision. The law regarding informed consent in an emergency situation is set out in Statutory Instrument 2006 No. 2984, The Medicines for Human Use (Clinical Trials) Amendment (No2) Regulation 2006. With appropriate regulatory control, studies of this group of patients are the best way to improve outcomes for those suffering such conditions in future. The British Heart Foundation Medical Director, Professor Peter Weissberg, said: “It is important to remember that whilst adrenaline is routinely used to treat a cardiac arrest, we don’t actually know whether this is a safe and effective practice. The concern is it could be doing patients more harm than good. The only way to answer this crucially important question is to do a well-designed clinical trial. It is always difficult to conduct a trial in situations where people are too ill to give their consent. But there are well established ethical guidelines for undertaking such studies. What is unacceptable is to continue giving a treatment that could be doing more harm than good. Only by undertaking difficult studies of this kind can we be sure that patients are receiving the highest possible standard of care and have the best chance of a good outcome.”

Frequently Asked Questions

Q. Why was my relative entered into this trial without anyone’s permission or knowledge?

A. We are aware of the sensitive nature of the circumstances in which patients will be part of the trial and of distress that relatives will be in at such a difficult time. We have given careful consideration to the need for a compassionate approach to relatives, to reduce further distress, and have discussed this in detail with both the ethics committee and with our patient/service user advisers for the trial. The trial was designed and conducted according to the legal and ethical requirements, and was independently monitored to ensure that patients’ rights, dignity and safety were paramount. When a person is unconscious due to their cardiac arrest we can’t ask permission about their treatment. Due to the urgent need for treatment we are not able to ask a relative or friend, should there be anyone else on scene. Research like the PARAMEDIC2 Trial is considered lawful and ethical, provided it has been scrutinised and reviewed by several regulatory organisations including an ethics committee (which is a panel of medical, scientific and legal experts, as well as representatives of the public) who review the research in terms of its importance to clinical practice and assess the risks and benefits of doing such a trial. The trial is then reviewed regularly by two independent monitoring committees, made up of representatives of the public and very experienced medical and scientific experts in the field. The research team, headed by an intensive care consultant who works in NHS hospitals as well as being a professor at the University Clinical Trials Unit, and other doctors, nurses, paramedics and scientists, were required to keep these organisations informed of the progress of the trial, and to report to an independent monitoring committee who had the authority to stop the research if there were major concerns about patient safety. Without research like this we would not be able to make improvements in patient care in the emergency setting.

Q. My relative died after being enrolled in this trial. I want to know what treatment my relative had.

A. If you decide you do want to know about the treatment your relative received we can tell you this, but we would like to meet with you to do this to be able to explain fully what the information means in order for it to be of help to you, and to offer you support at what we recognise will be a difficult time for you. A person who has a cardiac arrest in the community rather than in hospital, has less than a 10% chance of survival. Current treatments for cardiac arrest include basic life support (particularly chest compressions), defibrillation (an electric shock) and a range of medicines including adrenaline. Adrenaline has never been formally tested in humans with sufficient numbers to inform us reliably whether it is helpful or harmful, and recent studies have created substantial concern amongst doctors, nurses, paramedics and patients that adrenaline may be harmful when used as a treatment for cardiac arrest. To look at the effectiveness of adrenaline we need to collect data on 8,000 patients. However, it is very difficult to examine an individual patient’s treatment and decide if part of the treatment lead to the death.

South Central Ambulance Service NHS Foundation Trust (SCAS) is among 8 ambulance trusts in the UK taking part in vital research to address questions that clinicians and researchers have about the use of a medicine called glyceryl trinitrate (GTN) in the early phase of stroke.

A growing body of scientific evidence suggests that GTN may be beneficial to patients suffering stroke by lowering blood pressure and that the earlier this can be given the better. A patch, which is cheap and readily available, could be a simple new way for paramedics to routinely treat patients in an ambulance following a suspected stroke.


Use of patient information for research purposes

What is patient data?

SCAS staff will record information about your health. This will include your health problems, and the tests and treatment you have had. They might want to know about family history, if you smoke or what work you do. All this information that is recorded about you is called patient data or patient information.

When information about your health care joins together with information that can show who you are (like your name or NHS number) it is called identifiable patient information. It’s important to all of us that this identifiable patient information is kept confidential to the patient and the people who need to know relevant bits of that information to look after the patient. There are special rules to keep confidential patient information safe and secure.

What sort of patient data does health and care research use?

There are lots of different types of health and care research.

If you take part in a clinical trial, researchers will be testing a medicine or other treatment. Or you may take part in a research study where you have some health tests or answer some questions. When you have agreed to take part in the study, the research team may look at your medical history and ask you questions to see if you are suitable for the study. During the study you may have blood tests or other health checks, and you may complete questionnaires. The research team will record this data in special forms and combine it with the information from everyone else in the study. This recorded information is research data.

In other types of research, you won’t need to do anything different, but the research team will be looking at some of your health records. This sort of research may use some data from your GP, hospital or central NHS records. Some research will combine these records with information from other places, like schools or social care. The information that the researcher collects from the health records is research data.

Why does health and care research use information from patients?

In clinical trials, the researchers are collecting data that will tell them whether one treatment is better or worse than other. The information they collect will show how safe a treatment is, or whether it is making a difference to your health. Different people can respond differently to a treatment. By collecting information from lots of people, researchers can use statistics to work out what effect a treatment is having.

Other types of research will collect data from lots of health records to look for patterns. It might be looking to see if any problems happen more in patients taking a medicine. Or to see if people who have screening tests are more likely to stay healthier.

Some research will use blood tests or samples along with information about the patient’s health. Researchers may be looking at changes in cells or chemicals due to a disease.

All research should only use the patient data that it really needs to do the research. You can ask what parts of your health records will be looked at.

How does research use patient data?

If you take part in some types of research, like clinical trials, some of the research team will need to know your name and contact details so they can contact you about your research appointments, or to send you questionnaires. Researchers must always make sure that as few people as possible can see this sort of information that can show who you are.

In lots of research, most of the research team will not need to know your name. In these cases, someone will remove your name from the research data and replace it with a code number. This is called coded data, or the technical term is pseudonymised data. For example, your blood test might be labelled with your code number instead of your name. It can be matched up with the rest of the data relating to you by the code number.

In other research, only the doctor copying the data from your health records will know your name. They will replace your name with a code number. They will also make sure that any other information that could show who you are is removed. For example, instead of using your date of birth they will give the research team your age. When there is no information that could show who you are, this is called anonymous data.

Where will my data go?

Sometimes your own doctor or care team will be involved in doing a research study. Often, they will be part of a bigger research team. This may involve other hospitals, or universities or companies developing new treatments. Sometimes parts of the research team will be in other countries. You can ask about where your data will go. You can also check whether the data they get will include information that could show who you are. Research teams in other countries must stick to the rules that the UK uses.

All the computers storing patient data must meet special security arrangements.

If you want to find out more about how companies develop and sell new medicines, the Association of the British Pharmaceutical Industry has information on its website.

What are my choices about my patient data?

  • You can stop being part of a research study at any time, without giving a reason, but the research team will keep the research data about you that they already have. You can find out what would happen with your data before you agree to take part in a study.
  • In some studies, once you have finished treatment the research team will continue to collect some information from your doctor or from central NHS records over a few months or years so the research team can track your health. If you do not want this to happen, you can say you want to stop any more information being collected.
  • Researchers need to manage your records in specific ways for the research to be reliable. This means that they won’t be able to let you see or change the data they hold about you. Research could go wrong if data is removed or changed.

What happens to my research data after the study?

Researchers must make sure they write the reports about the study in a way that no-one can work out that you took part in the study.

Once they have finished the study, the research team will keep the research data for several years, in case they need to check it. You can ask about who will keep it, whether it includes your name, and how long they will keep it.

Usually your hospital or GP where you are taking part in the study will keep a copy of the research data along with your name. The organisation running the research will usually only keep a coded copy of your research data, without your name included. This is kept so the results can be checked.

If you agree to take part in a research study, you may get the choice to give your research data from this study for future research. Sometimes this future research may use research data that has had your name and NHS number removed. Or it may use research data that could show who you are. You will be told what options there are. You will get details if your research data will be joined up with other information about you or your health, such as from your GP or social services.

Once your details like your name or NHS number have been removed, other researchers won’t be able to contact you to ask you about future research.

Any information that could show who you are will be held safely with strict limits on who can access it.

You may also have the choice for the hospital or researchers to keep your contact details and some of your health information, so they can invite you to take part in future clinical trials or other studies. Your data will not be used to sell you anything. It will not be given to other organisations or companies except for research.

Will the use of my data meet GDPR rules?

GDPR stands for the General Data Protection Regulation. In the UK we follow the GDPR rules and have a law called the Data Protection Act. All research using patient data must follow UK laws and rules.

Universities, NHS organisations and companies may use patient data to do research to make health and care better.

When companies do research to develop new treatments, they need to be able to prove that they need to use patient data for the research, and that they need to do the research to develop new treatments. In legal terms this means that they have a ‘legitimate interest’ in using patient data.

Universities and the NHS are funded from taxes and they are expected to do research as part of their job. They still need to be able to prove that they need to use patient data for the research. In legal terms this means that they use patient data as part of ‘a task in the public interest’.

If they could do the research without using patient data they would not be allowed to get your data.

Researchers must show that their research takes account of the views of patients and ordinary members of the public. They must also show how they protect the privacy of the people who take part. An NHS research ethics committee checks this before the research starts.

What if I don’t want my patient data used for research?

To invite you to take part in a research trial we use personalised letters, send an email or an SMS, call you directly on your phone or invite you at a point of contact we have with you. We also use posters and social media to disseminate an invitation. You will have a choice about taking part in a clinical trial testing a treatment. If you choose not to take part, that is fine.

In most cases you will also have a choice about your patient data being used for other types of research. There are two cases where this might not happen:

  • When the research is using anonymous information. Because it’s anonymous, the research team don’t know whose data it is and can’t ask you.
  • When it would not be possible for the research team to ask everyone. This would usually be because of the number of people who would have to be contacted. Sometimes it will be because the research could be biased if some people chose not to agree. In this case a special NHS group will check that the reasons are valid. You can opt-out of your data being used for this sort of research. You can ask your GP about opting-out, or you can find out more.

Who can I contact if I have a complaint?

If you want to complain about how researchers have handled your information, you should contact the research team ( ). If you are not happy with their response you have the right to contact the Trust’s Data Protection Officer (

Should you still have concerns or believe they are processing your data in a way that is not right or lawful, you can raise a concern or complain to the Information Commissioner’s Office (ICO) (  or 0303 123 1113).

Patient information and health and care research

All NHS organisations (including Health & Social Care in Northern Ireland) are expected to participate and support health and care research. The Health Research Authority and government departments in Northern Ireland, Scotland and Wales set standards for NHS organisations to make sure they protect your privacy and comply with the law when they are involved in research. Our research ethics committees review research studies to make sure that the research uses of data about you are in the public interest, and meet ethical standards.

Health and care research may be exploring prevention, diagnosis or treatment of disease, which includes health and social factors in any disease area. Research may be sponsored by companies developing new medicines or medical devices, NHS organisations, universities or medical research charities. The research sponsor decides what information will be collected for the study and how it will be used.

Health and care research should serve the public interest, which means that research sponsors have to demonstrate that their research serves the interests of society as a whole. They do this by following the UK Policy Framework for Health and Social Care Research. They also have to have a legal basis for any use of personally-identifiable information.

How patient information may be used for research

When you agree to take part in a research study, the sponsor will collect the minimum personally-identifiable information needed for the purposes of the research project. Information about you will be used in the ways needed to conduct and analyse the research study. NHS organisations may keep a copy of the information collected about you. Depending on the needs of the study, the information that is passed to the research sponsor may include personal data that could identify you. You can find out more about the use of patient information for the study you are taking part in from the research team or the study sponsor. You can find out who the study sponsor is from the information you were given when you agreed to take part in the study.

For some research studies, you may be asked to provide information about your health to the research team, for example in a questionnaire. Sometimes information about you will be collected for research at the same time as for your clinical care, for example when a blood test is taken. In other cases, information may be copied from your health records. Information from your health records may be linked to information from other places such as central NHS records, or information about you collected by other organisations. You will be told about this when you agree to take part in the study.

Keeping information for future research

Information about you that is collected during a research study may be kept securely to be used in future research in any disease area, including research looking at social and economic factors affecting health. This may include combining it with information about you held by other health or government organisations such as NHS Digital. Usually the information is combined together by matching information that has the same NHS number. Doing this makes maximum use of the information you have provided and allows researchers to discover more.

Researchers may not be able to specify all the possible future uses of the information they keep. It could include providing the information to other researchers from NHS organisations, universities or companies developing new treatments or care. Wherever this happens it will be done under strict legal agreements. The information about you will be depersonalised wherever possible so that you cannot be identified. Where there is a risk that you can be identified your data will only be used in research that has been independently reviewed by an ethics committee.

On rare occasions NHS organisations may provide researchers with confidential patient information from your health records when we are not able to seek your agreement to take part in the study, for example because the number of patients involved is too large or the NHS organisation no longer has your contact details. Researchers must have special approval before they can do this.

Your choices about health and care research

If you are asked about taking part in research, usually someone in the care team looking after you will contact you. People in your care team may look at your health records to check whether you are suitable to take part in a research study, before asking you whether you are interested or sending you a letter on behalf of the researcher.

In some hospitals and GP practices, you may have the opportunity to sign up to a register to hear about suitable research studies that you could take part in. If you agree to this, then research nurses, researchers or administrative staff authorised by the organisation may look at your health records to see if you are suitable for any research studies.

It’s important for you to be aware that if you are taking part in research, or information about you is used for research, your rights to access, change or move information about you are limited. This is because researchers need to manage your information in specific ways in order for the research to be reliable and accurate. If you withdraw from a study, the sponsor will keep the information about you that it has already obtained. They may also keep information from research indefinitely.
