2 SIGA Saúde SIGA Saúde is São Paulo City s Integrated and Distributed System for Managing the Public Healthcare System. The system belongs to São Paulo City, which is willing to share it with other cities, states and countries. SIGA Saúde has been developed using free-software open-code concepts. São Paulo is the largest city in South America, with 12M inhabitants and some 22M in the Metropolitan Area. Initial Figures: 400 Primary Care Units 60 Polyclinics 160 Hospitals SIGA Saúde is present in 100% of 11M Users São Paulo City public health care providers 8.5M Emergency T/year 550k Inpatients/year 11M Primary Care C/year 2

24 SIGA Saúde Development Strategy: Key Issues Well-defined software development process Component-driven software development Well-defined project guidelines and coding standards Continuous integration Strong project management Knowledge sharing 24

25 SIGA Saúde Technical Strategies Use of open standards and open source paradigms Based on Java / Java EE Three Tiers presentation, business and persistence Linux Web based Thin Clients at the point-of-care Database independence 25

26 SIGA Saúde Technical Strategies HTML WEB Container Application Server EJB Container Session Façades Entity Beans Service Classes and SLS Beans Utility Classes Database 26

27 SIGA Saúde Project Management Well-defined issues tracking process, using a web-based tool for managing all project tasks; All project members had real time visibility of what was going on in the project; When new tasks were created, delays happened or tasks were finished, an was automatically generated informing the person responsible for the task; This technique gave us important metrics that helped to keep the project within schedule and improved the communication among the team members. 27

29 SIGA Saúde Proven Benefits Patient Flow Organization & Control Supports the Reference-Counter-Reference Model Finds the Shortest & Most Resolving Way Through the HC System Manages & Operate the Whole Health System Identifies all HC Units, Workers & Their Relationships Uniquely Understands and Qualify the Demands Connecting the Health System Connects Internal & External Units & Functions Reduces Costs & Increases Productivity HL7 v3.0 Project to Connect Accredited Labs to SIGA Saúde The Electronic Health Record Identifies each Individual / Patient Uniquely Knows the Patient s Clinical History Helps Healthcare Workers do their Job (Decision Support) Still Many Things to Do Hospital Information Systems + Full EHR Further Improve the Clinical Content with Archetypes 29

30 SIGA Saúde: Advantages of the Architecture Several cities can share servers and services; Simple machines at the point of care; No need for computer personnel at healthcare units; Complexity stays away from the user, under central control; Model can be rolled out to other places; New functionalities can be added easily; SIGA Saúde: Periodic Updates 30

31 Next Steps for SIGA Saúde Full EHRS On-line lab reports: 8 labs using LOINC + HL7 v3 content + Brazilian national schemas for interoperability operational in Sep 2008 Municipal Hospitals IT Project Health Information for the Citizen Empowering the patient Distance Learning TeleHealth 31
