A state board in charge of developing a universal health plan for all Oregonians will delay the release of its final report to lawmakers, citing uncertainty over how to pay for it. Even with the extra time, none of the board’s nine members expressed confidence the report would answer the perplexing question of how to finance a state-based, single-payer health care system. Uncertainty over finances helped sink efforts to enact single-payer health care in Vermont and California. “We don’t have the weapons to fight the 30-second sound bite,” said Chunhuei Chi, Oregon State University health care finance scholar and board member. The most recent figures presented to the board show that a single-payer plan in Oregon would have a 3% administrative cost.
