  4. PHCDM Project Purpose The purpose of the Public Health Conceptual Data Model (PHCDM) project is to document the information needs of public health so that Centers for Disease Control and Prevention (CDC) and its state and local partners in public health can: • Establish data standards for public health, including data definitions, component structures, code values, and use; • Collaborate with national health informatics standards setting bodies to define standards for the exchange of information among public health agencies, and healthcare providers; • Construct computerized information systems that conform to established data and data interchange standards for use in the management of data relevant to public health. PHCDM Governments Project Special Interest Group Presentation

  5. Overall Scope of Work • Development and maintenance of the Public Health Conceptual Data Model (PHCDM) • Development and maintenance of the Public Health High-level Process Model (PHHPM) • Implementation of the PHCDM and PHHPM • Coordination with national data-related standards • Coordination with CDC Program, State, and Local public health data-related initiatives PHCDM Governments Project Special Interest Group Presentation

  6. PHCDM Project Goals • Provide a framework for organizing public health data standards and guidelines • Reduce development effort for computerized information systems for public health surveillance • Enhance data exchange capabilities among public health agencies and healthcare providers • Represent public health data needs to national standards setting bodies • Facilitate collaboration between CDC and their state and local partners in public health. PHCDM Governments Project Special Interest Group Presentation

  7. PHCDM Jun-Dec 1999 Accomplishments • Created a data model for public health based upon analysis of the database structures of current CDC disease surveillance systems, CIPHER data standards, the HL7 RIM, and other health related information models, and defined a maintenance process for the model. • Reviewed the PHCDM with epidemiologists from within certain program areas of CDC and from state and local public health agencies and updated the PHCDM based upon their critique. • Selected a computerized information system development project to make use of the PHCDM and CIPHER data standards within CDC and developed a workplan for applying the standards to the development effort. • Established Jan-Jun 2000 objectives for the PHCDM project. PHCDM Governments Project Special Interest Group Presentation

  8. PHCDM Jan-Jun 2000 Accomplishment • Published the premiere edition of the PHCDM • Participated in the HL7 Reference Information Model (RIM) harmonization process to introduce public health related information needs. • Began development of a public health high-level process model (PHHPM) to provide context for the PHCDM. • Continued to coordinate with CDC programs and partners to endure that their information needs are represented in the PHCDM • Established Jun-Dec 2000 objectives for the PHCDM project.

  16. NEDSS Cooperative Agreement Initiatives PHCDM Governments Project Special Interest Group Presentation

  17. PHCDM and NEDSS • The PHCDM project is one of many interrelated activities supporting CDC’s National Electronic Disease Surveillance System (NEDSS) initiative. • The long-term vision for NEDSS is a collection of complementary computerized information systems that automate the process of gathering health data, facilitate the monitoring of the health of communities, assist in the analysis of trends and detection of emerging public health problems, and provide information for setting public health policy. • The focus of the NEDSS initiative is the development, testing, and implementation of information management technology standards that will support more complete and comprehensive integration of computerized health information systems for use in public health. PHCDM Governments Project Special Interest Group Presentation

  18. NEDSS Systems Architecture • Brings structure, standards and interoperability to the information systems elements of surveillance • Allows the latitude for states and local health departments to do specific implementations and fulfill public health needs • Is respectful of local / state / federal data flow issues • Provides a structure around which CDC systems can be integrated • Facilitates the ready exchange of comparable data and reports between public health organizations without reprogramming PHCDM Governments Project Special Interest Group Presentation
