A legislative committee holds a hearing tomorrow on Attorney General Mike Hatch's audit of Allina Health System. Hatch's year-long investigation found the health care company overspent millions on administrative costs and wasted millions more on executive perks. But as lawmakers begin their inquiry into Hatch's findings, employers and workers say they are more concerned with rising health insurance rates. The state health department says premiums increased for five consecutive years in 2000. Last year's increase was 16 percent. Some health care experts say if the upward trend continues employers may look for alternatives to managed care or stop offering health insurance altogether. Minnesota Public Radio's Tom Scheck has the first installment in our series, "Managing Managed Care."
