and ethical rules4CSE 300 Introduction and Motivation (Outcome)Introduction and Motivation (Outcome)Patient suffersPatient suffersRepeats information to different kinds of entityNo simple way to find information in times of emergencyQuality Quality 8th leading cause of death in US in medical errorsDuplicate patient information may be lead to repeated testing due to conflicts1/3 spending on healthcare goes to fix the duplication$2.7 trillion estimated expenditure by 2010 but not number 1 in health care services5CSE 300 Introduction and Motivation (Solutions)Introduction and Motivation (Solutions)TechnologyTechnologyGive the entities especially patients to choose health servicesAdoption of connected computer systems could reduce error and moneyInternet can be used to deliver health information quicklyStandardize health data exchangeUse the current systems instead of making new onesCreate a non-proprietary “network of networks” that will support rapid health information flow6CSE 300 Role of SOARole of SOASignificant work in independent healthcare areaSignificant work in independent healthcare areaPHREMRMedication Management toolChronic disease management toolsNeed to connect various systemsNeed to connect various systemsService Oriented ArchitectureService Oriented ArchitectureProvides ways to connect disparate systemsConnect at edge of one system7CSE 300 Role of SOA (healthcare)Role of SOA (healthcare)Common Framework of standards at National LevelCommon Framework of standards at National LevelData ExchangeSecurity and AuthorizationData IntegrityAll built as servicesAll built as servicesUsing such services to integrate various existing Using such services to integrate various existing systemssystemsNo redesigning of existing systemsSecure integration without jeopardizing patients and providers confidential data8CSE 300 Service Oriented ArchitectureService Oriented ArchitectureService Oriented ArchitectureService Oriented Architecture9CSE 300 Service Oriented ArchitectureService Oriented ArchitectureDefinitionDefinitionThe policies, practices, frameworks that enable application functionality to be provided and consumed as sets of services published at a granularity relevant to the service consumer.Services can published, discovered and invokedAbstracted away from the implementation using standards-based form of interfaces.One can think “functions” in a program as services1.Hides the implementation2.Discoverable by the library it belongs3.Can be invoked to get results4.Publishable through a libraryOne can think “functions” in a program as services1.Hides the implementation2.Discoverable by the library it belongs3.Can be invoked to get results4.Publishable
