Connected Health Reference Architecture Nuwan Bandara Senior Lead, Solutions Architecture WSO2

Connected health as a concept

What drives connected health Governments Citizens Healthcare organizations Health insurance organizations World health care institutions Research entities / Universities

Connected health vision Building an information sharing ecosystem with all connected health care entities

Goals in healthcare business Intelligence via information sharing Decrease latencies in connected services Providing the best possible service through accurate and timely information sources Reduce manual executions to reduce human errors (i.e data entry etc.) High availability of medical information Big data analytics for healthcare research

The business architecture healthcare cloud Integrated healthcare ecosystem

Technology landscape in healthcare Heterogeneous devices / applications / data formats / protocols (i.e hospital information system) heterogenous integrations in a hospital

Devices & Services Classic use-case where devices and services connects to a private cloud

Protocols & Data formats HL7 (v2 / v3 / FHIR) over HTTP SOAP / XML over HTTP REST / JSON over HTTP Messaging over JMS XML, CSV over FTP Custom binary protocols (certain HC devices) Legacy CORBA based systems

Interoperability Interoperability issues are solved via a bus architecture in Health Care Information System (HCIS) interoperability with healthcare bus architecture

Data federation & mediation In a distributed HCIS data can reside in multiple different locations Some data needs to be consolidated before consumption Aggregation of data can be a function of data federation and service mediation

Data federation & mediation data bus HCSB cloud services

Data governance & entitlement Distributed transactions (maintaining the ACID properties in health data) Who can access the data From where the data is accessed Entitlement policies

Data governance & entitlement data bus HCSB cloud services identity & entitlement bus

Complex health events Readings of healthcare devices (HC telemetries) Alerts and events of registered patients Scheduling of surgeries / patient care Insurance claim management Disease control and vaccination related alerts Hospital inventory management Equipment maintenance alerts

Complex health events HC cloud complex events processor HCSB event queue email / alerts dashboards

Availability and scalability Healthcare PaaS Elastic scaling on demand Minimum HA setup Availability zones and regions
