Creating a Public Health Information SystemCreating a Public Health Information SystemPublic ofessionalStep 1 — Vision and System PlanningEnvision solutions, opportunities, and application ofinformation technology in public healthBroad knowledge of public health practice, proficiency ininformation technology, and capacity for innovationStep 2 — Health Data Standards and IntegrationDefine and design health data standards andtransformation (e.g., HL7, ICD, SNOMED) and health domainintegration (e.g., ELR, EHR, CMS, HIE, surveillance,demographics, social media)Design and implement databases, tables, columns, dataformats, and keys for linking tables and data to supportdefined health data standards and integrationExpertise in health data standards, database design, anddata linking and integration across health systemsExpertise in relational/SQLdatabases and unstructureddata design and managementStep 3 — Data Privacy and SecurityDefine and implement health data privacy and HIPAAregulationsImplement and enforce data, systems, and communicationsecurityKnowledge of health data privacyUnderstanding information technologysecurity functionsStep 4 — Systems Design and ImplementationDefine and design methods for public health functions, dataelements, data flow, case definitions, and messagemappingImplement information technology for defined functions,data elements, data flow, and case definitionsStep 5 — Visualization, Analysis, and Reporting of HealthDataExpertise in health systemsand data interoperabilityExpertise in managing informationtechnology systems developmentExpertise in public health practice,business intelligence, decisionmaking, and use of analytic softwareCMS Centers for Medicare and Medicaid Services; EHR electronic health record; ELR electronic laboratory record; HIE healthinformation exchange; HIPAA Health Insurance Portability and Accountability Act; HL7 Health Level 7; ICD International Classification ofDiseases; SNOMED Systematized Nomenclature of Human Medicine; SQL structured query language.16

Step 1 — Vision and System PlanningHardwareSoftwareCommunicationTechnology17

Step 2 — Health Data Standardsand IntegrationHealth data standards andintegration are required whendefining the data.Centers for Disease Control and Prevention (CDC). Meaningful use—introduction. Atlanta, GA: US Department of Health andHuman Services, CDC; 2012. tml.18

Step 3 — Data Privacy and SecurityData privacy and security mustbe identified, prescribed, andimplemented throughout thedata lifecycle.19

Step 4 — Systems Designand Implementation Define or design methods forpublic health functions, dataelements, data flow, casedefinitions, and messagemapping Implement informationtechnology for defined publichealth functions, dataelements, data flow, casedefinition, and similar needs20

Step 5 — Visualization, Analysis,and Reporting of Health DataVisualization and implementationof the required analysis, reporting,and meaningful use of the datacollected and managed by thesystem.21

Informatics in Action — CDC’s FluViewA clear-cut way to sharenational influenza data wasneeded by the public health community,clinicians,scientists, andthe general public22
