Research
We are proud to be a research-active organisation, which means we develop and host research studies which contribute to and improve emergency medical care and patient outcomes in the UK and worldwide.
As London has such a diverse population with a variety of health conditions and needs, we have a wide-ranging research portfolio to work with and can investigate a number of different topics. And not just in clinical areas; as we’re a large organisation we can also explore organisational and workforce issues too.

How can I start a research project with you?
All proposed research involving London Ambulance Service staff, our patients or their data must be formally considered through our Trust Research Approval process. This application process includes a feasibility assessment of the study and consideration of whether or not the research will be of benefit to the Trust.
We welcome opportunities for collaborative research with academic, commercial and third sector organisations, as well as with other NHS Trusts.
For student research projects, we accept applications from staff who have substantive contracts with our Trust and are undertaking research as part of an educational qualification. However, we do not have the capacity to support external student’s requests for research that is below PhD level.
PhD research proposals will be considered on a case-by-case basis and may be supported if undertaken collaboratively with LAS, and if the project aligns with our research priorities and there is no overlap with our own research programme.

Completed research projects
PARAMEDIC2
This trial, funded by the NIHR Health Technology Assessment, aimed to understand whether using adrenaline is helpful or harmful when treating someone experiencing a cardiac arrest outside of a hospital. The study ran between 2014 and 2017. PARAMEDIC-2 is officially the largest cardiac arrest drug trial in Europe, involving 8,014 patients (2,102 recruited by the LAS) and the largest randomised placebo-controlled trial examining the role of adrenaline in cardiac arrest.
Background
Adrenaline has been an integral component of advanced life support for over 50 years, but it had not previously been fully tested to see if it is beneficial for patients who have a cardiac arrest outside of hospital. This randomised controlled trial compared the clinical and cost effectiveness of adrenaline versus a saline placebo for the treatment of out-of-hospital cardiac arrest. Drugs were blinded so that paramedics were unaware of which drug they were administering. All other aspects of resuscitation practices remained unchanged.
Four other ambulance trusts also participated in the trial (South Central, North East, West Midlands and Wales). The trial was supported by the International Liaison Committee on Resuscitation, Resuscitation Council (UK), College of Paramedics and the Joint Royal College Ambulance Liaison Committee.
Results
The trial found that, after 30 days, adrenaline resulted in a slight increase in survival but much greater likelihood of severe disability.
The results were published in August 2018 in the New England Journal of Medicine. Further details can be found on the trial website.
PARAMEDIC-2 was listed in the top 100 papers for 2018 (#27) in terms of the Altmetric score.
RIGHT-2
This trial, funded by the British Heart Foundation, aimed to understand whether glyceryl trinitrate (GTN) improves outcomes for patients who experience a stroke. The study ran between 2016 and 2018.
Background
High blood pressure (BP) is common in stroke patients and generally associated with poor outcomes. This trial aimed to understand if using GTN as soon as possible after the onset of a stroke improved patients’ neurological outcome. This randomised controlled trial involved paramedics administering either GTN or placebo patches to patients within four hours of them experiencing symptoms.
Six other ambulance trusts (East Midlands, West Midlands, East of England, South West, South East Coast and Wales) also participated in the trial.
Results
The trial found that pre-hospital treatment with GTN for patients with presumed stroke does not appear to improve functional outcome.
The results were published in February 2019 in The Lancet.
PRE-HOSPITAL EMERGENCY DEPARTMENT DATA LINKING PROJECT
This mixed-methods research project, funded by the Health Foundation, aimed to determine the feasibility of and potential learning from retrospectively linking ambulance service data to Emergency Department (ED) data to create a continuous electronic record of the patient journey.
The project was run in collaboration with Swansea University, the Nuffield Trust, and Kingston University and St. George’s University of London.
Background
Historically, front line ambulance crews would take a patient to hospital and, often, would have little to no further information about the patient’s outcome during and/or following their stay in hospital. The Pre-Hospital Emergency Department Data Linking Project (PHED Data) was designed to see if linking ambulance service data to hospitals’ would lead to benefits for the patient without compromising confidentiality.Results
PHED Data showed it is possible to link ambulance data to ED data across multiple sites, which would suggest that national implementation would also be feasible using the same method.NHS England has since approved the bid to run this project nationally. The results of the project now form the Ambulance Data Set which will standardise and link data nationally, and will be rolled out across all ambulance services and emergency departments across England.

'STRETCHED' Research study – privacy notice
This patient notification contains information about our research study STRETCHED – a study to see if people who call the 999 ambulance service often can be better helped and how it will utilise a patient’s data
What is the study about?
Ambulance services are assessing how they respond to the small number of people who frequently phone 999 (more than five times a month or 12 times in three months), but sometimes without a medical problem requiring immediate treatment. Some services have introduced local “case management” initiatives, with referrals to a team from different agencies (social services; primary care (GP); community mental health services; Emergency Departments; ambulance service) that devises individualised ‘treatment plans’, aiming to reduce callers’ need to contact emergency services.
We will study: the characteristics of people who call frequently; what is currently being done for them; what helps them to stay well and not need to call 999 or other emergency services; and assess how well case management helps them. Using routinely collected NHS data information for four ambulance services, we will: see if frequent callers have fewer emergency episodes when ‘case management’ is available; gauge the safety of this method; and determine associated costs and savings. We will also interview: patients treated through case management to explore how they feel about this service; and health, social care and other professionals involved in case management to identify operational issues in providing such initiatives.
More information about our study can be found on the PRIME Centre Wales website. Our research is funded by the National Institute of Health Research.
What data will be collected and how it will be used?
Ambulance services collect personal data (name, address, postcode, NHS number, date of birth and gender) for data quality and data linkage purposes. The research team will only receive pseudo-identifiers – a long sequence of letters and numbers that enables us to link the datasets in question – age, and gender. It will not be possible for the research team to identify any patient from this code. The research team will not carry out any automated decision making or profiling using your information. Inclusion in this study will not affect the care you receive in any way.
Data processing is carried out under Articles 6 (1) (e) and 9 (2) (j) of the General Data Protection Regulations (GDPR). Data will be stored in a secure environment within Swansea University and only accredited researchers will have access to this data. Patient level data will not be shared with any other person or organisation. Study outputs will only report grouped data, and we will ensure that individuals cannot be identified in them. Data security arrangements within Swansea University conform to standards specified by the Health Research Authority, NHS Digital, NHS Wales Informatics Service and UKSeRP. Your data will be archived for 5 years following the study.
Who has reviewed the study?
Our research has been approved by the Health Research Authority, following review by Wales Research Ethics Committee 4 (19/WA/0216) and the Confidentiality Advisory Group (19/CAG/0195).
How we will report our findings?
At the end of the study we will publish our results in peer-reviewed, Open Access academic journals, ensuring that anyone who wishes to can access the results free of charge. We will also present the study at relevant emergency and urgent care conferences. In addition, we will produce an end of study report for interested parties including:
• Our funder – NIHR
• Ambulance staff who participated in the focus groups
• Other study stakeholders, including patient and public involvement representativesIt will not be possible to identify any patient from the published results.
