PHCDM Project PurposePHCDM 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.

Overall Scope of WorkOverall 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 Project GoalsPHCDM 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 PHCDM Jun-Dec 1999 AccomplishmentsJun-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.


8

PHCDM PHCDM Jan-Jun 2000 AccomplishmentJan-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.

• Desired Changes to the RIM– Add Informal Organization as a specialization of Organization

– Add Formal Organization as a specialization of Organization

– Add Individual as a specialization of Stakeholder

– Make Person a specialization of Individual

– Make Living Subject a specialization of Individual

• Additional Changes to the RIM– Change the name of Stakeholder to Party

Public Health Public Health High-Level Process ModelHigh-Level Process Model

• Surveillance Planning– Identify the health-related problem to be addressed– Understand the setting in which surveillance and response activities will take place– Define the scope of surveillance– Develop policies and procedures for conducting surveillance

• Case Monitoring– Identify parties meeting case definitions and record information about them– Report cases to responsible parties– Analyze data to identify problems and trends– Investigate and confirm suspected cases– Communicate results of analyses and investigations

• Disease Intervention– Take action to prevent or control disease

– Evaluate usefulness of surveillance and effectiveness of outbreak response activities

17

PHCDM and NEDSSPHCDM 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.


18

NEDSS Systems ArchitectureNEDSS 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


19

Implement an integrated data repository• able to be patient centered, non-categorical• support “thick” client and web applications • (ODBC, JDBC and ANSI SQL)

Integrated State / Local DataRepository


20

28

NEDSS Cooperative Agreement InitiativesNEDSS Cooperative Agreement Initiatives

• Assessment and Planning – Assess current information systems personnel and technical infrastructure, evaluate that infrastructure against the NEDSS systems architecture and develop plans to migrate to the NEDSS architecture as needed.

• Element Development – Implement between one and four of the NEDSS system architecture elements and use in the setting of identified public health activities.

• Charter Sites - Conduct activities to implement and demonstrate the fully described systems architecture. Charter sites will receive funds for implementation of up to four system architecture elements and to ensure that new and existing elements work together as an integrated whole by prototyping the use of the full systems architecture to supply validated data for existing surveillance systems.


29

Availability of FundsAvailability of Funds
