Connected Health Reference Architecture

Connected Health Reference ArchitectureShiroshica KulatilakeArchitect, Solutions Architecture WSO2AgendaAn overview of Connected HealthTowards building a Connected Health architectureReference ArchitectureDemoOverviewConnected Health as a concept

What drives Connected HealthGovernmentsCitizensHealthcare organizationsHealth insurance organizationsWorld health care institutionsResearch entities / UniversitiesConnected health vision Building an information sharing ecosystem with all connected health care entities

Goals in healthcare businessProviding the best possible service through accurate and timely information sourcesDecrease latencies in connected servicesReduce manual executions to reduce human errors (i.e data entry etc.)High availability of medical informationIntelligence via information sharingBig data analytics for healthcare researchThe business architecture

healthcare cloudIntegrated healthcare ecosystemBuilding blocks for Connected HealthTechnology landscape in healthcareHeterogeneous devices / applications / data formats / protocols (i.e hospital information system)

heterogenous integrations in a hospitalDevices & ServicesClassic use-case where devices and services connects to a private cloud

Protocols & Data formats HL7 (v2 / v3 / FHIR) over HTTPHL7 (v2) over MLLPSOAP / XML over HTTPREST / JSON over HTTPMessaging over JMSXML, CSV over FTPCustom binary protocols (certain HC devices)Legacy CORBA based systemsInteroperabilityInteroperability issues are solved via a bus architecture in Health Care Information System (HCIS)

interoperability with healthcare bus architecture busData storage and transformationIn a distributed HCIS data can reside in multiple different locations

Data would be stored in different formats

There would be data which is common across several entities

Some data needs to be consolidated before consumption

Aggregation of data can be a function of data federation and service mediationData federation & mediation
