Preventing Overdiagnosis: A research programme to investigate and respond to the health impacts of expanding disease definitions and lowering diagnostic thresholds

过度诊断的“现代流行病”被认为是医疗保健中伤害和浪费的来源。当某人被诊断出患有不会伤害他们的疾病时，就会发生过度诊断，从而导致不必要的治疗。该项目将调查扩大疾病定义如何通过标记太多人来帮助推动过度诊断，如何沟通问题，以及如何改善定义疾病的过程，以便卫生资源可以更多地关注那些最需要的人。

The “modern epidemic” of overdiagnosis is recognised as a source of harm and waste in healthcare. Overdiagnosis happens when someone is given a diagnosis for a disease that won’t harm them, leading to unnecessary treatment. This project will investigate how expanding disease definitions are helping drive overdiagnosis by labelling too many people, how to communicate about the problem, and how to improve the process of defining disease, so health resources can focus more on those most in need.
