Feasibility study for a minimum viable proposition of an augmented reality app for Great Ormond Street Hospital to prevent distress and anxiety for paediatric patients needing MRI scans

仅在美国，每年就进行近4000万次MRI扫描，诊断成像的成本很高。在英国，2018年10月至2019年9月期间，共进行了4520万次成像检查，其中346万次是磁共振成像（MRI）。儿童约占成人MRI统计数据的10%，可能需要接受MRI扫描出于各种原因（例如头部受伤、神经炎症）。这种经历可能会令人痛苦和不安，尤其是对于幼儿来说。扫描的质量取决于孩子静静地躺30分钟到一个多小时。如果他们感到痛苦，扫描将需要再次进行，否则孩子将需要镇静或全身麻醉。这项可行性研究是为大奥蒙德街医院的患者开发一款增强现实应用程序的MVP，这些患者需要在家准备MRI扫描，以减少需要镇静和全身麻醉的儿童数量。预防与医院程序有关的心理问题，还确保患者体验更愉快，身心健康更好，从而减轻社会护理系统的长期负担。

With nearly 40 million MRI scans performed annually in the United States alone, diagnostic imaging costs are substantial. In the UK, between October 2018 and September 2019, there were 45.2 million imaging tests of which 3.46 million were Magnetic Resonance Imaging (MRI).Children account for approximately 10% of adult MRI statistics and may need to undergo MRI scans for a variety of reasons (eg head injuries, neuro-inflammatory conditions).The experience can be distressing and upsetting especially for young children. The quality of the scan relies on the child lying still for 30 minutes to over an hour. If they become distressed, the scan will need to be done again or the child will need sedation or general anaesthetic.This feasibility study is to develop a MVP for an augmented reality app for Great Ormond Street Hospital patients that need MRI scans to prepare from home in order to reduce the numbers of children needing sedation and general anaesthetic.Prevention of psychological issues relating to hospital procedures, also ensures a happier patient experience and better physical and mental outcomes which reduces the longer-term burden on the social care system.
