The global-local tension in medical education: turning 'think global, act local' on its head?

It is yet too early to fully accept that 'think global, act local can be turned on its head'. There is much research to be carried out, particularly on the outcomes and impacts of medical education. Establishing cause and effect is a challenge, as is determining whether globalisation or localisation can contribute to greater global health equity. If we are ever to resolve the global-local tension in medical education, we need more evidence on the outcomes of what we do, whether globally or locally inspired.
