The commissioner of health shall set annual cost containment goals for public and private spending on health care services for Minnesota residents, as provided in paragraph (b). The cost containment goals must be set at levels the commissioner determines to be realistic and achievable but that will reduce the rate of growth in health care spending by at least ten percent per year for the next five years. The commissioner shall set cost containment goals based on available data on spending and growth trends, including data from group purchasers, national data on public and private sector health care spending and cost trends, and trend information from other states.
