Technically, the Philippine Health Information Exchange serves the following purposes:
a. Ease the unification and integration of health data and processes across different health facilities employing disparate electronic medical record systems;
b. Promote interoperability by providing means for communication and coordination of electronic health data among the various health domains (i.e. disparate clinic information systems, and applications) without loss of semantics;
c. Increase accountability for the proper management of health information;
d. Harmonize and optimize eHealth processes and workflows;
e. Serve as reference in the development of integrated information systems
f. Promote the implementation and use of interoperability standards.
From the viewpoint of business process owners, the PHIE aims to achieve integrated healthcare services and delivery that is also seamlessly responsive, efficient, cost-effective, and real-time. Specifically, the system will aid in:
a. Enabling secured data sharing between authorized healthcare providers and consequently, supporting protected access to clients health data record across providers in many geographic areas of the country;
b. Providing a single unified view of clients health data record across health facilities whether a hospital or clinic through an interface that is accessible anywhere and anytime; thereby, enhancing client care collaboration;
c. Facilitating aggregation of health data into a longitudinal electronic medical record; and
d. Generating accurate and real-time health statistical reports for monitoring and evaluation, with subsequent development of appropriate interventions, policies, and protocols.
The PHIE is composed of six (6) interacting components, namely:
a.Client Registry manages the unique identification of citizens receiving healthcare services.
b.Provider Registry - manages the unique identification of healthcare providers.
c.Health Facility Registry manages the unique identification of places where health services are administered.
d.Standards Terminology Service manages the unique identification of clinical activities, standard health data sets, terminologies and formats.
e.Shared Health Record a repository of clients records with information in the exchange.
f.Interoperability Layer receives communication from various application systems being used by the health facilities, and orchestrates message processing.
Point of service applications, i.e. the systems used by the health facilities such as hospitals, rural health units, and clinics to access and update the clients records interact with the PHIE. Examples of these are the DOHs Integrated Hospital Operations and Management Information System (iHOMIS), and Integrated Clinic Information System (iClinicSys) used by government hospitals and rural health units, respectively, for recording and updating a clients medical record. One of the essential end-products of this component is a unified client-centric electronic medical record that can be securely shared among healthcare providers.
