Clalit, Israel’s largest HMO, claims to have cut the cost of treating diabetes by 40% per patient in the last 6-7 years. We talk to head of community medicine, Nicky Lieberman.

Clalit has 14 hospitals, 1,400 community outpatient clinics and its own pharmacy and diagnostic networks serving 4 million members.
