GHX was formed in March 2000 and provides an open and neutral electronic trading exchange, along with complementary products and services, to improve efficiencies and reduce costs for the healthcare supply chain. A privately held company, GHX is the only electronic trading exchange owned and governed by representatives from both buyers and suppliers of healthcare products and services. While initially founded by some of the largest manufacturers in healthcare, owners of GHX include manufacturers, distributors, providers (hospitals), and group purchasing organizations (GPO’s).
