Inoperability - Research Paper Example

(2010). All these applications applied individually will support communications through interfaces which demand for constant maintenance and modification due to their dynamism. This as one way of attaining operability has not proved worthwhile. Similarly, there is standardization of an interface can as well be employed in attaining operability since this method eliminates the extra cost which would be incurred when building separate interfaces. The second approach is fuel by the fact that application developers are able to construct applications that are in line with the standardized interfaces, this increases the prospects of interoperability hence reducing cost which also includes reduced maintenance costs since there is a drop in the number of the interfaces to be accorded maintenance.

The health level seven (HL7) is an application protocol for exchange of data in the healthcare environment. It is developed to be used to transfer data of healthcare information from department or function to the other basing its applications on the vast concept of application to application exchange of message system. The HL7 is the unit in form of an atom that passes data through systems. Or instance, the HL7 facilitates the admission of patience to a hospital or giving a lab order for blood test (Au, S, 2003).

Every world real world event is defined by HL7 through an abstract messaging system which is comprised of a group of segments in a defined criterion and the rules and regulations for the construction of such abstract is created by the HL7 developed message framework which comprises of elements which are the building blocks and follows a hierarchy in context. Individually, the elements are associated by the factors like option ability, value set, length and data form that gives a constraint to them.

The other components such as segments and segment groups are likely to compose additional elements while sub-components are purely primitive in nature since they are in the position of holding a data value without having a descendant structure Electronic Healthcare Information Security. (2010). HL7 was not there in the past but in the onset of its development, it was basically formed to give room too many dynamic business procedures that face the healthcare industry. However, the wider forms resulted into standardization which in turn created so many optional parts hence the alignment of the implementation of interfaces proved futile.

HL7 applications are normally joined in two ways that is point to point or through the middleware which is clearly shown by the interface engine outcomes. Point-to- point applications entails the connection of each pair of applications in an independent way while the middle way application is the process where all the applications are connected centrally to the message broker. The operating system interconnection separates the functions of the protocols into five main layers with every layer having only a function of the layer that is found below it.

This is the protocol stack and it is used for implementation in the software or hardware with the lower layers in the hardware and the higher in the software Data Exchange Standards, Health Level Seven Version 2.5 an application protocol for electronic data exchange in healthcare environments.
