Worlds apart? Healthcare technologies for lifelong disease management

When viewed from the developing world, the prospects or implementation of adequate healthcare technologies are dim unless world inequality is corrected.

Expensive instruments become useless if plugged in the wrong voltage. When the maintenance support base is 5,000 or 10,000 km away, what's the use of transferring any technology?.
