WASHINGTON  The Bush administration issued a grim report on the financial outlook for Medicare and Social Security on Tuesday, but said that, by two important measures, the condition of the programs had not deteriorated since last spring.

The new reports, like those issued last April, said that Medicare’s hospital insurance trust fund would be exhausted in 2019, while Social Security’s reserves would be depleted in 2041.

“Medicare poses a far greater financial challenge,” said Treasury Secretary Henry M. Paulson Jr., the managing trustee of Medicare and Social Security.

The reports may put pressure on the presidential candidates to say what they would do to rein in health costs and to shore up the programs, which serve more than 50 million people. The candidates have largely avoided these questions, but the next president will not be able to escape them.
