Khunti K, et al. – The aim of this work was to conduct a systematic review and meta–analysis to distinguish how therapeutic inertia in the management of hyperglycaemia was measured and to assess its extent over the past decade. In context of the findings, therapeutic inertia in the management of hyperglycaemia in patients with type 2 diabetes is a major concern. This is well documented in Western countries, but corresponding data are urgently required in low– and middle–income countries, in view of their high prevalence of type 2 diabetes.
