ABSTRACT
Abstract The functional building blocks of EHRs now exist in most hospitals and providers’ offices. Some states have connected the many host systems from the healthcare organizations together and used HIEs as their interoperability solutions. Some states like New York and groups of states like New England and Maryland-Delaware-DC have their host-centric HIE models using a common shared approach. This message-to-host and back interoperability is very focused on providers, hospitals, labs, pharmacies, and radiology facilities, each connecting to and through the statebased innovation hub. They are dependent on each state following through and getting onboard. Even if money has been provided, this is difficult. But with cloud technology and the emerging information-centric networking approaches, an alternative interoperability approach can be defined. The EHR systems will still have to support host-to-host-centric approaches and evolve to a patient-consumer-information-centric interoperability architecture, leveraging new standards.
