ACT-FAST. ACcurate diagnosis for Triage and treatment and AI enabled STroke care Networks

在英国，每五分钟就会发生一次中风。它可以发生在任何人身上，任何年龄，任何时间，是医疗紧急情况，紧急治疗是必不可少的。一个人越早接受中风治疗，可能发生的损害就越小。中风是一种常见的、毁灭性的疾病，最常见的是由动脉堵塞或脑动脉出血引起的。目前中风患者中，三分之一死亡，三分之一致残，三分之一活下来过正常生活。尽管最近预防性中风治疗取得了进展，但英国每年仍有大约10万例中风病例。中风的诊断仍然是临床诊断，只能通过医学成像确诊，通常是CT扫描。准确的诊断还依赖于及时、正确地读取扫描图像，然后与专家中心共享图像，以便计划和提供治疗。虽然中风治疗已经取得了重大进展，但诊断仍然存在重大延误，因为通常很难在最初的扫描中发现，而且目前的技术还不支持与专业中心及时共享扫描结果。这可能导致对中风患者的治疗延误，也可能导致不必要地将非中风患者转移到专科中心。ACT FAST项目旨在通过评估技术的使用来克服这些问题，该技术可以在医院之间快速共享图像，并使用该平台开始测试先进的人工智能（AI）工具，这些工具将帮助临床医生读取扫描结果以诊断中风。这类工具已经在其他国家得到应用，在中风护理方面具有切实的效益和效率。除了评估这样一个共享平台如何增强NHS中风护理的性能外，我们还将使用已经建立的中风研究数据集，并创建一个存储库，在该存储库上，基于人工智能的临床决策支持工具可以进行首次测试和二次交付。加快在区域网络中获得脑卒中成像并提供先进的决策支持工具将缩短做出更准确诊断的时间。一个人越早接受中风治疗，可能发生的损害就越小，他们就越有可能康复并过上正常的生活。

Stroke strikes every five minutes in the UK. It can happen to anyone, of any age, at any time and are a medical emergency where urgent treatment is essential. The sooner a person receives treatment for a stroke, the less damage is likely to happen.Stroke is a common and devastating condition which is most commonly caused by a blockage of an artery or bleeding from an artery in the brain.Of patients that have a stroke currently, a third die, a third are disabled and a third survive to live a normal life. Despite advances in recent preventative stroke care there are still around 100,000 strokes in the UK per year.The diagnosis of stroke remains a clinical one and is only confirmed with medical imaging, typically a CT scan. Accurate diagnosis also relies upon the scans being read in a timely manner, correctly and then sharing images with specialist centres where treatments can be planned and delivered.Whilst there have been major advances in stroke care, there are still significant delays in the diagnosis as it is often difficult to detect on the initial scans and current technology does not readily support scans being shared in a timely manner with specialised centres. This can lead to delays in treatment for stroke victims and also the unnecessary transfer of non-stroke patients to specialist centres.The ACT FAST project aims to overcome these problems by evaluating the use of technology that enables sharing imaging rapidly across hospitals and also using the platform to begin to test advanced Artificial Intelligence (AI) tools that will aid the clinicians in reading the scan to diagnose stroke.Such tools are already deployed in other countries with tangible benefits and efficiencies in stroke care. As well as assessing the performance of how such a sharing platform could augment delivery of stroke care in the NHS, we will also use an already established stroke research data set and create a repository on which clinical decision support AI based tools can be first tested and second delivered.Speeding up access to stroke imaging in a regional network and providing access to advanced decision support tools will reduce the time to make more accurate diagnosis. The sooner a person receives treatment for a stroke, the less damage is likely to happen and the more likely they will be to recover and lead a normal life afterwards.
