(AP) WASHINGTON - Is it too good to be true?

Health care spending has eased up recently, bringing a welcome respite for government and corporate budgets. But experts who track health care's economic indicators like the vital signs of a patient disagree on the diagnosis and what the future holds.

One explanation for the slowdown says it's a temporary consequence of the recession and an economy that can't seem to hit its stride. A more hopeful view says American medicine is moving from disjointed solo practice to teamwork models aimed at keeping patients healthier, and that's a permanent change.

It's not a stretch to say the future of U.S. health care depends on the answer. If the system can reform itself from within to reduce waste and deliver better results, it will help stave off sharp cuts to hospitals and doctors, as well as more cost shifts to their patients, working families with employer coverage and older people in Medicare.

Two doctors - one in Washington state, the other in Montana - come to different conclusions about what they're seeing.

Dr. Glen Stream of Spokane, Wash., says he sees the reason for the slowdown through patients in his examination room. A 55-year-old tech worker with diabetes, self-employed and uninsured after being laid off, is unable to afford brand-name medications. A 50-year-old woman at risk of liver cancer is refusing regular MRI scans for early detection. Although she has fairly good insurance, the copayments are too high.

"Far and away it is related to economic issues," Stream said. "I see people who have medical conditions who I should be seeing every three months. They tell me they can only afford to come in every six months or once a year."

Dr. Doug Carr of Billings, Mont., doesn't dispute the impact of the economy, but says long-lasting improvements are coming together beneath the surface and will emerge.

Carr is medical director for education at the Billings Clinic, in the forefront of developing something called a "patient-centered medical home." It's basically general-medicine doctors, physician assistants and nurses who closely follow patients with chronic illnesses to try to keep them from developing complications that require hospital treatment. More than 30 states are experimenting with the model, as are Medicare and major insurers and employers.

"We are seeing in early pilots up to a 10 percent reduction in premiums," said Carr. The savings stem mainly from fewer trips to the emergency room and less hospitalization, but also from better coordination that avoids duplicative and pricey imaging tests.
