“A health information exchange (HIE) consists of the technology, standards, and governance that enable the exchange of data between the information systems of various health care stakeholders”- (Wager, et.al, 2009) This is because a system that corresponds with different standard cannot work with each other, therefore the need of standards were developed. Ad Hoc, De facto, Government Mandate, and Consensus are the four methods that have been used to developed IT standards in USA. However, with the booming IT industry and the introduction of WWW and Internet the web standards are now developed by much less formal groups.
In my research, I came across a website named HLN Consulting LLC where different types of standards were explained in technical and quite simple terms. According to them the first is Process Standard – which defines, how health data should be used, within the organizational workflow and participate in the interoperability example American Health Information Community (AHIC). Second is Technical Standard –which defines the structure, syntax and consistency of interoperable tasks. Example HL7. (HLN Consulting llc, 2013)
Whereas, (Wager, et.al, 2009) discussed many standards including HL7 and ASCX12N that are important to the health sector, as they provide both the broad standards for all types of applications and specific standard focusing on one type of application.
a) Health Level Seven Standard’s (HL7) purpose is to develop a messaging standard to support the “exchange, management and integration of data that support patient care.” HL7 is at the highest level in OSI network reference model, which deals with the various network issues like data exchange, timing of the exchange and the communication error between the applications. HL7 Version 2 messages are most commonly used in the healthcare sector for the exchange of laboratory results, patient admissions, discharges and transfers and many other types of information.
b) Digital Imaging and Communications in Medicine – the growth of digital imaging gave birth to the standards for electronic transfer of digital images among the different vendors. The purpose was to specify a set of protocols for the network communications and media storage, including a file format and a medical directory structure.
c) National Council on Prescription Drug Programs – NCPDP promotes the standard for the transfer of data among pharmacies. NCPDP offers its members a support, resources, educational opportunities and database services. Their standard...
