Wal-Mart may expand its 140 in-store health clinics by partnering with outside vendors to provide chronic and preventative health care services for everything from HIV and diabetes to pregnancy testing. "What they're thinking is, as the health care reform act rolls out and we have another 30 million people covered by some level of insurance, now these people will have to get access," says Jeffrey Hoffman, health care strategist with consulting firm Kurt Salmon. Wal-Mart issued a "Request for Information" at the end of October seeking partners to help the retailer develop a "low-cost primary care health care platform," first reported by Kaiser Health News and NPR. In a statement Wednesday, Wal-Mart downplayed suggestions of a nationwide initiative, calling its own plans "to build a national, integrated" system "overwritten and incorrect."
