Abstract:
Recent IT advancements have resulted digital collection of health related information. There
exist diverse health information systems today, each addressing a speci c need in the healthcare
domain e.g. Hospital Information System collecting clinical, patient and administrative data;
Health Management and Information Systems (HMIS) collecting health indicators across an
area (such as mortality, births and vaccination) and systems for Telemedicine to provide access
to healthcare for areas that are not easily accessible. Integrating the information collected
across such diverse systems can be technically challenging, primarily due to the di erent data
models and work
ows being adopted to address speci c requirements catered by such systems.
However, such integration can provide signi cant bene ts such as single point of access, detailed
and real-time analysis and reduction in duplication of information.
In this work, we present a case study of integrating OpenMRS based hospital information systems
and DHIS2 based HMIS deployed across the state of Himachal Pradesh (HP), India. OpenMRS
based system is now deployed across 20 hospitals in the state while the DHIS2 based system is
used for data collection from multiple reports under NRHM program. We used WHO backed
interface for statistical data and metadata exchange in healthcare called SDMX-HD for data
communication across the systems. We present the system architecture in detail and provide
discussion on challenges and learning from development and deployment of such a system across
the state of HP. We also discuss the data being collected at present and some analysis which
can done to get useful insights from this data. We also looked into some external factors which
might be in
uencing the healthcare setting in the state.
