More than a quarter of 1,000 doctors, consumers and industry professionals surveyed by Greenway Medical Technologies cited interoperability as a top concern when using health IT systems. Other concerns raised by respondents include medical staff alignment and overall costs. "The report reinforces the need for hospitals and health care providers to take a lead role in three major trends impacting patient care -- data electronification, consumerism and population health improvement," said Greenway President and CEO Tee Green.
