Federal and state officials have unveiled a new program to help consumers choose a nursing home. The program grades nursing homes and ranks them. The information is available through the Medicare consumer Web site www.medicare.gov or through the toll-free number 1-800-MEDICARE. Missouri’s advocate for the elderly, Lieutenant Governor Joe Maxwell, says there is no one single answer to the question of how nursing home quality can be improved. He says the information provided by Medicare will be very helpful, but won’t replace a personal visit to the nursing home before it is selected.
