In the healthcare system, interoperability is the ability of different information technology systems and software applications to communicate, exchange data, and use the information that has been exchanged (NAHIT,2005). Exchange of health data is an essential factor for the healthcare industry. Health data exchange can increase the quality of care of the patient by providing relevant health related information for better patient management, knowledge management, and performance monitoring.
In an effort to reduce costs and increase the quality of service, the government has provided over $26 billion in economic incentives to promote the adoption of health information exchange (HIE) platforms among medical providers. The full implementation

There is three primary infrastructure of health data exchange models: centralized, federated and hybrid. Centralized HIE model is simple, but it also effective for aggregating health information from multiple sources. it helps to the provider to improve the quality of care and patients outcomes. And it also managed by a strong central authority. This centralized model links with the payers, providers and public health data sources from a single data warehouse. Centralized model is used by regional and state level including HealthInfoNet in Maine, INHS Health Information Network serving parts of Washington State and Idaho, and MyHealth Access Network in Oklahoma. All of these communities include population health management and data analytics as part of their core missions and have successfully used centralized HIE to provide reporting that can help providers improve the quality of care and patient outcomes. Decentralized HIE model is, where heath data stays to its source and…show more content…
For an example, HL7 (Health Level Seven International) is a set of standards, formats, and definitions for the exchange, management, and integration of data that supports clinical patient care and the management, delivery, and evaluation of health care services. HL7 standards, developed and promulgated by the healthcare IT standard-setting authority HL7 International are the de facto standards in healthcare IT, though some HL7 users have called on Congress to create stronger legal interoperability standards for the healthcare IT industry. EHR system functional model created by HL7 includes advanced decision support feature for the healthcare industry. Which designed to help for national interoperability of healthcare IT systems. This model is designed to provide a guideline to healthcare professionals as well as healthcare related researchers in preparing, acquiring and transitioning EHRs. Updated version of HL7 allowed interoperability among electronic Patient Administration Systems (PAS), Electronic Practice Management (EPM) systems, Laboratory Information Systems (LIS), Dietary, Pharmacy and Billing systems as well as Electronic Medical Record (EMR) or Electronic Health Record (EHR)
