Many health care providers think health reform efforts could give them a headache.

IVANS Inc., Stamford, Conn., has published that conclusion in a summary of results from a recent survey of physicians and other health care providers.

About 72% said a shift to a “pay for performance” system would improve patient outcomes, but 79% said it would increase their operating costs.

About 60% predicted a national health insurance plan would increase their costs or have no effect.

Half said they doubt whether new government spending on health information technology will do much to persuade physicians to adopt new information technology systems.
