The index is particularly timely as the nation considers proposals to reduce sharply the role of the federal government in financing health care, along the lines proposed by Paul D. Ryan, Republican of Wisconsin and chairman of the House Budget Committee.
The index measures the total cost of health care for a typical American family of four covered by a preferred provider plan, widely known as a P.P.O. The index’s great virtue is that it includes not only the employer’s and employee’s contributions to the premium for P.P.O. coverage but also the out-of-pocket expenses the family has under the plan.Employers can control the growth of health insurance premiums by shifting more and more of the cost from the insurance policy to the family’s budget, through higher deductibles and coinsurance or by excluding benefits from coverage that had previously been covered.
Thus, the index provides a more accurate picture of the actual burden of health spending for a typical American family than does just the premium for P.P.O. coverage..."
