Cloud-based EHR Interoperability Takes Front Stage
Because our industry is still in diapers, we focus on the lack of basic interoperability and ruminate on why EHR vendors struggle (aka, refuse) to share even basic patient data. But we must take heart, health IT friends, stiffen our upper lips and look to trends and examples that create optimism (i.e., help get us out of bed in the morning): 21st century interoperation is happening in health IT. In a recent interview with Healthcare Dive, Athenahealth CEO Jonathan Bush laid out a vision for how the cloud is the disruptive technology to bring healthcare into the Internet age. He describes “level three interoperation,” where two cloud-based systems connect once and support multiple interoperations that accomplish more than just data sharing.
