Perspectives from China, India and Sri Lanka on the drivers and potential solutions to overuse and overdiagnosis

Overuse is defined as provision of healthcare which is more likely to result in harm than good, and it is fast becoming a threat to human health and the sustainability of health systems world- wide.1 Overuse may, but not always, increase the risk of overdiagnosis, which occurs when someone is diagnosed with a disease that would have never caused them harm if not recognised and is a well- known adverse outcome of screening. 2 3 Overuse and overdiagnosis have a different signification when it occurs in LMICs, where wise utilisation of the already limited healthcare resources is paramount, especially in the COVID-19 pandemic era.
