Rating systems for hospitals are many, but they can be confusing and, some say, not actually helpful.

Oregon began disclosing hospital infection rates last month. For now, these reports cover only three kinds of care: heart bypass surgery, knee-replacement surgery and the use of central-line catheters in intensive care.

Researchers in Boston compared five well-known reporting services and found that they consistently disagreed on the top- and bottom-performing hospitals. Two hospitals, for example, ranked last for bypass surgery by at least one service scored first or second in other rankings. Most rating systems didn't perform statistical tests to prove that apparent differences were meaningful.
