Supported Research Projects
The ASES study: Aortic Syndrome Evidence Synthesis
Steve Goodacre, Professor of Emergency Medicine, The University of Sheffield
The ASES project is funded by the NIHR: National Institute for Health and Care Research, to discover how we could utilise clinical scores and blood tests to determine which patients in the emergency department require a CT aortogram. Experts in emergency medicine, surgery, imaging, statistics, and health economics are among those on the research team, as are two public representatives from the Aortic Dissection Charitable Trust.
The initiative will examine all existing research on clinical scores and blood tests to see how well they detect acute aortic syndrome. Following that, a computer model will be created to mimic how doctors would manage a population of patients with symptoms suggestive of acute aortic syndrome if alternative diagnostic procedures were applied. To select patients for a CT aortogram, the strategies will employ a clinical score and/or a blood test. The model will predict the outcomes for patients and the costs to the NHS of various solutions.
As a result, emergency medicine will be able to select the technique that achieves the optimal balance of preventing misdiagnosis while not requiring too many CT scans. This initiative will also highlight gaps in current knowledge that require additional investigation.
The Royal College of Emergency Medicine has made the diagnosis of acute aortic syndrome one of its top ten research priorities. The ASES study will ensure we make the most of the current evidence to help diagnose acute aortic syndrome and determine where future research is best focused.
The DAShED study: Diagnosis of Acute Aortic Syndrome in the Emergency Department
Matt Reed, Professor of Emergency Medicine, University of Edinburgh
The DAShED research is an observational cohort study funded by the Royal College of Emergency Medicine (RCEM) of patients visiting the ED with symptoms consistent with Acute Aortic Syndrome (AAS).
Previous research has identified several strategies for ruling out AAS that combine clinical probability scoring with blood tests (such as D-Dimer), but when these strategies are applied to a large population, such as those presenting to the ED, with a relatively low number of actual cases, they result in a high rate of computed tomographic angiography (CTA) scanning. Overtesting has a substantial economic and resource impact, as well as higher radiation risks leading to later cancer development, delays in CT scanning for patients with other conditions, and the detection of ‘incidentalomas,’ or the discovery of anomalies whose relevance is unknown.
The DAShED project will examine the features of ED visits with potential AAS and assess the service implications of various diagnostic techniques. DAShed will guide future research which we hope ultimately will lead to a standardised universal ED diagnosis route for all patients presenting to the ED with suspected AAS.
DAShED accepted its first patient on September 26, 2022, and will continue to accept patients until November 30, 2022. As of November 21st, nearly 3000 people had been enrolled on the study, which is taking place in the emergency departments of 27 hospitals across the UK. Follow-up will be complete by the end of 2022 and study results will be revealed in Spring 2023. Detailed information on this project including the clinical poster, patient information and protocol is available at EMERGE; the Emergency Medicine Research Group of Edinburgh.
DAShED is the first study attempting to really understand the broad presentation of patients to Emergency Departments who may have symptoms of Aortic Dissection.
DAShED is set to understand how ED clinicians currently chose to investigate for this time critical, potentially catastrophic condition which can be so difficult to detect amongst the myriad other potential diagnoses, and how we can standardise this in future to reduce the currently unacceptable rate of misdiagnosis.
EARNEST: Early Aortic Repair in patients Needing Endovascular Surgery for Type B Aortic Dissection
Colin Bicknell, Consultant Vascular Surgeon, Imperial College London
Approximately seven out of ten patients with type B aortic dissection have uncomplicated aortic disease with no immediate life-threatening complications. They are typically treated with the best medical treatments, including rigorous blood pressure monitoring, high blood pressure medication, and yearly aorta scans. However, one in every three individuals develops an aortic aneurysm, which must be corrected or there is a considerable risk of rupture and internal haemorrhage. This procedure is difficult and dangerous, with a high chance of death.
An earlier treatment known as thoracic endovascular aortic repair (TEVAR) may be preferable. Surgeons reline the aorta with a stent graft by a keyhole method a few months after the dissection. The treatment enables the aorta to heal while preventing it from expanding and rupturing.
This project is in the final round of competition for funding by the NIHR: National Institute for Health and Care Research, to determine if early thoracic aortic stenting in patients with uncomplicated type B aortic dissection is clinically and economically beneficial.
All participants will be evaluated for a period of five years. The most common outcome is death from aortic disease, major stroke, paralysis, or serious heart and lung illness. The experiment will investigate whether this composite result is lower in the TEVAR group compared to the normal care group, who may require a complex aortic repair at a later date, and whether this method is good value for money in the NHS.
If this experiment demonstrates a benefit to early TEVAR, thousands of patients worldwide could have their aorta relined at an early stage, avoiding complex aortic surgeries if there is late aortic deterioration.
This is a unique opportunity to run this trial in the UK. Definitive evidence regarding the clinical and cost effectiveness of early TEVAR for uncomplicated type B aortic dissection is badly needed.
If this trial shows a benefit to early TEVAR, across the world, each year, thousands of patients may have their aorta relined at an early stage and not have to undergo complex aortic operations when there is late degeneration of the aorta.
CAASP: A multi-centre service evaluation project to understand current acute aortic syndrome (AAS) pathways
Dr Jim Zhong , Interventional Radiology Fellow, Leeds Teaching Hospitals NHS Trust
Mr Sandip Nandhra, Clinical Lecturer, Newcastle University & President of the Vascular and Endovascular Research Network
Aortic dissection is not recognised or considered as a possibility in the diagnosis of acute aortic syndrome (AAS), and one in every five patients dies before reaching the hospital. To avoid life-threatening complications, early hospital admission and rigorous blood pressure control are essential. Only 2 out of every 10 patients will survive if the aorta bursts.
A quick diagnosis is essential to start the appropriate treatment. However, because dissection is uncommon in comparison to other more prevalent medical issues that can present similarly and resemble AD, such as a heart attack, bone or joint pain, or a blood clot in the lung, there may be delays in identifying AD. Because aortic dissection care is time-sensitive, these delays might have a negative impact on patients’ outcomes. Diagnosis is almost usually detected on a CT scan, which is sometimes conducted for other reasons (i.e. not looking for an aortic dissection).
This Collaborative Acute Aortic Syndrome Project will examine all individuals who had a CT scan in their local hospital (with symptoms presumably caused by an AAS) to determine how many actually had an aortic dissection. The study will then focus more thoroughly on those patients who have a fresh aortic dissection to examine if the diagnosis (and subsequent management) was made on time and, if not, why the delays occurred. We will also look at how these delays affected their outcomes six months following the initial diagnosis in terms of survival and the number of aortic surgeries.
The Collaborative Acute Aortic Syndrome Project is a research partnership with the Vascular and Endovascular Research Network (VERN), British Society of Interventional Radiology (BSIR), British Society of Endovascular Therapy (BSET), Vascular Society of Great Britain and Ireland (VSGBI), Circulation Foundation, Cardiothoracic Interdisciplinary Research Network (CIRN) and TADCT.
