Kaiser Permanente gets perfect four-star rating on HMO score card

Kaiser Permanente got a perfect four stars for medical care on an annual HMO score card that California officials hope consumers will use to shop for health coverage. The report card rates the state's eight largest HMOs primarily on preventive measures, including what portion of an HMO's enrollees received recommended tests on schedule. Kaiser garnered four stars because the HMO excelled at meeting national standards on 34 clinical indicators.
