Achei uma definição de DOWNSTREAM RISKS em http://www.gilweber.com/gw_pro19.htm:
What is "Downstream Risk"?
"Downstream risk" is a term you'll be hearing more and more. It describes situations in which an intermediary (e.g., an IPA) signs a master, capitated contract with an insurer (e.g., an HMO), and then signs subcontracts with individual physicians or groups. As so often happens, if the deal isn't actuarially sound or if the intermediary isn't up to managing the task, the risk and the adverse consequences ultimately are passed to the doctors, who don't get paid for their services despite the fact that the IPA was paid.

And because the doctors don't hold direct contracts with the HMO and are subject to the IPA's management decisions, they're helpless, at the bottom of the food chain. They're "downstream," where all the problems eventually flow.
THANKS!!!
