Using healthcare wisely: reducing inappropriate use of tests and treatments

过度诊断和过度治疗是现代医疗保健的意外后果，因为扩大了疾病定义，将有轻微问题或疾病风险较低的人贴上标签，诊断测试确定无关紧要的异常，以及筛查程序检测不会进展的疾病。其结果是极大的危害和不可持续的过度使用。我们将研究过度诊断和过度治疗的发生率、原因和后果，评估解决方案并广泛传播研究结果。

Overdiagnosis and overtreatment as unintended consequences of modern healthcare due to expanded disease definitions labelling people with mild problems or at low risk of illness, diagnostic tests identifying inconsequential abnormalities and screening programs detecting disease that won’t progress. The result is much harm and unsustainable overuse. We will research the prevalence, causes and consequences of overdiagnosis and overtreatment, evaluate solutions and widely disseminate findings.
