The White House on Thursday made good on President Obama's pledge to evaluate the medical malpractice system and take steps to discourage "defensive medicine" and frivolous lawsuits.

All without committing much money.

Health and Human Services Secretary Kathleen Sebelius announced her department would award $25 million in grants to states and health care systems to test new patient safety and medical liability measures and review existing state laws that discourage malpractice suits, by channeling claims through screening panels or out-of-court mediation.

At a White House briefing, Sebelius echoed the administration's line, by saying she didn't think malpractice suits were really driving health costs off the rails -- as some conservatives in Congress claim. But she allowed that the threat of litigation was chilling professionals in specialties like obstetrics and neurosurgery, by forcing them to order more diagnostic tests and take other potentially costly precautions.
