More Americans getting multiple chronic illnesses

By Will Dunham

WASHINGTON (Reuters) - More Americans are burdened by chronic illnesses such as diabetes and high blood pressure, often having more than three at a time, and this has helped fuel a big rise in out-of-pocket medical expenses, a study released on Tuesday showed.

With prescription drugs playing a key role, average annual out-of-pocket medical costs -- those not covered by health insurance -- rose from $427 per American in 1996 to $741 in 2005, researchers wrote in the journal Health Affairs.

Adjusting for inflation, that translated to 39 percent more in out-of-pocket spending per person over that time, according to Kathryn Paez of Maryland-based health research organization Social & Scientific Systems Inc. and colleagues.

The figures were much higher among the elderly. For example, a person insured through the Medicare program for those 65 and older who had three or more chronic conditions paid an average of $2,588 of out-of-pocket medical expenses.

A separate report published in the journal on Tuesday showed U.S. health care spending rose to $2.2 trillion in 2007, or $7,421 per person.

Based on government survey data, 44 percent of Americans in 2005 had at least one chronic medical condition, which could include diabetes, high blood pressure, high cholesterol levels, cancer, arthritis, heart failure and others. That compares to 41 percent in 1996.

The study did not look directly at the causes of the increases, but there appear to be several factors.

The rise in Americans with multiple chronic illnesses comes as obesity and sedentary lifestyles have grown more common. Obesity contributes to many chronic ailments including diabetes. U.S. health officials say the rate of new cases of diabetes soared by about 90 percent in the past decade.
