Q1: Proposed solution concerning interoperability, standards and HER architecture
Health informatics is the storing, retrieving, acquiring and using the healthcare
information to promote improved cooperation between patient’s diverse healthcare providers.
Health informatics plays a significant role in the push towards healthcare reforms. It is a growing
occupation that links information communication technology and healthcare to improve the
excellence and protection of patient care. Health informatics applies informatics concepts and
theories to real-life situations to accomplish improved health outcomes.
EHR refers to a healthcare record in a computer processable format which put in nutshell
readability but includes the impression that information is required to be agreeable to
programmatic management and hence to habitual dispensation (Ciampi, De Pietro, Esposito,
Sicuranza & Donzelli, 2012,). The interoperability is the aptitude of two or more applications
being able to correspond in a valuable approach exclusive of compromising the content of the
transmitted electronic health records. It is imperative to build up national standards for the EHR
interoperability to be able to distribute patient health information among health professionals in a
multidisciplinary collective concern atmosphere and also share patient health information
between organizations within an activity, a local or nationwide health system and maintain
interoperability between software from diverse users.
Several levels can address the interoperability distress, the levels of theoretical
interoperability model can facilitate in accurately defining what category of interoperability is
required. In electronic health records, it is crucial to surmount interoperability; procedural
interoperability is exceeded using a standard communication protocol, the exploit of open
standards and the allocation of the data information model allows the overcoming of the

syntactic interoperability (Bott, 2004). The data model at the logical level is alienated into
theoretical models; this dissection follows the storage area pattern. The registry model is
communal among particular systems to guarantee syntactic and semantic interoperability. The
storage area model does not necessitate being interoperable for the reason that each structure
manages the medical credentials in its way (Tolk & Muguira, 2003).
The access policy manager that stores and safe keep the patient’s data allows the users to
execute the defense requirement such as discretion, integrity, dependability, endorsement, and
liability. The employ of security model follows the ideology of the WSS security standard. The
necessity of prudence is achieved in the course of the use of an encrypted patient identifier
categorically to keep delicate records detached from healthcare information through the secure
switch over manipulate. Additionally, the admittance to information is restricted by the exploit of
reception control (Bott, 2004).
This enables the users to access the medical records without any difficulty in real life
which in turn helps in serving the public interest. It defines the architectural representation of
communication to sustain interoperability and security of different regional electronic health
records result in it also look for ways to present patients the aptitude of specifying and
supervision access rights on their health care credentials in a self-motivated approach. The
solution is to employ professionals who can interpret the standards so that they can be
understood by users of healthcare information (Bossen, 2006).
