Slide 6 EHR SD RM - EHR Way Forward … Future State Reference Architecture Cost Effectiveness Proposition Target cost function of healthcare IT connectivity # of service consumers * # of services

Slide 7 EHR SD RM - EHR Way Forward … Future State Reference Architecture Approximately 75 U.S. Immunization Information Systems (IISs) Completely connected point-to-point IIS network: 74 * 75 / 2 = 2775 connections Assume 200 regional provider EHRs per IIS: 200 * 75 = 15,000 connections Each connection costs $10K-$30K per side $40K each * 17,775 =$711,000,000 Point to Point Messaging Economics 7Copyright 2009 Software Partners

Slide 8 EHR SD RM - EHR Way Forward … Future State Reference Architecture Labs Meds Allergies Cancer Registries Joint Replacement Registries Chronic Disease Registries Adverse Event Reporting …etc. Intra-enterprise communication Provider-to-Provider communication domains increases cost to $71,100,000,000 Expand to Multiple Domains 8Copyright 2009 Software Partners

Slide 11 EHR SD RM - EHR Way Forward … Future State Reference Architecture Bus architecture Plug-and-play connections Common information model How to Solve? 11 Copyright 2009 Software Partners

Slide 12 EHR SD RM - EHR Way Forward … Future State Reference Architecture Bus architecture –Build common carrier once –Hide routing, translation Plug and play connections –Eliminates cost on one side of each connection Common information model –multiple platform-specific models for a single platform- independent model –Basis for passing data from service to service Cost Reduction Opportunities 12 Copyright 2009 Software Partners

Slide 13 EHR SD RM - EHR Way Forward … Future State Reference Architecture 75 IISs each accessing one service 15,000 EHRs, installations ea = 500 connections is per service consumer only $20K * ( ) =$11,500,000 + cost of carrier Drive down the $20K Cost Reduction Opportunities 13 Copyright 2009 Software Partners

Slide 15 EHR SD RM - EHR Way Forward … Future State Reference Architecture Proposed Meaningful Use Comments Propose use of service interfaces to satisfy need for transport layer standards for immunizations Fill gaps in immunization standards –Include immunizations in medical summary –Use CAP133 Immunization Content in Table 2A –Include immunizations in decision support clauses Note the immunization use case includes patient identification
