President Clinton will propose federal legislation today to create a broad new set of government standards aimed at guaranteeing Americans better care and more clout in the nation's changing health care system, according to White House officials.

The officials said that Clinton plans to give his full endorsement to a health care "bill of rights" that would assure insured patients easier access to treatment, more information to help them select health plans and doctors, and new ways to appeal if they are dissatisfied with their care.

The president plans to call on every U.S. health insurer to adopt these patient protections, which were proposed by an advisory commission that completed work on the plan yesterday. Clinton also will instruct the federal agencies that oversee health insurance to spend three months studying which of the safeguards can be enforced under existing law. But White House officials said the president has concluded that many facets of the commission's proposal will require Congress to act.
