Voluntary purchasing pools: a market model for improving access, quality, and cost in health care. American College of Physicians.

States and small businesses have been rapidly establishing voluntary health care purchasing pools during the past few years. Purchasing pools can decrease health care costs, improve access for some small businesses and individual persons, allow greater choice among health care plans, and provide continuity of care. Purchasing pools also help to even the balance of power in the health care marketplace, which has come increasingly under the control of huge proprietary managed care corporations. This position paper of the American College of Physicians discusses how a system of well-designed voluntary purchasing pools can help protect the integrity of health care in the emerging managed care marketplace.
