Abstract:
Health standards i.e. Health Level 7 (HL-7), Fast Healthcare Interoperability Resources
(FHIR) etc are being defined in order to have communication and data sharing between different
eye hospitals and clinics. As patients move around the healthcare ecosystem, their electronic health
records must be available, discoverable, and understandable. Further, to support automated clinical
decision support and other machine-based processing, the data must also be structured and
standardized. OpenMRS is a collaborative project to develop software to support the delivery of
health care in developing countries. It is intended as a workflow automation that many
organizations can adapt to develop a system. Integrating the Healthcare Enterprise (IHE) promotes
the coordinated use of HL7 standards to address the clinical needs. IHE standards support clinical
practice and the management, delivery, and evaluation of health services, and are recognized as
the most commonly used in the world. FHIR is a new specification based on emerging industry
approaches. In this research, we aim to improve healthcare workflows for ophthalmology based
on IHE radiology workflow. In order to achieve this goal, we have blended IHE radiology
workflow, Picture Archiving and Communication System (PACS) and middleware of MIRTH
connect engine to optimize eye care workflows. We have specifically used HL7 v2.5, v2.6 and
DICOM standard 3.0 to maintain backward compatibility with DICOM supported machines. The
proposed workflow is tested for different case studies related to eye care facility
