NMI Glossary

Term	Description
Implementation Template and User Guide	A common guide for all audiences tasked with implementation of NMI messaging, this template merges information from the NNDSS HL7 Message Mapping Guides (MMGs), NMI HL7 Message Specification, and PHIN Vocabulary Access and Distribution System (PHIN VADS). For public health agency (PHA) program subject matter experts, this template serves as the means to perform gap analysis (PHA’s existing data vs CDC’s requested data) and provides the mapping to the local data elements. For the PHA IT implementers, it serves as the underlying structure for the integration engine, provides mapping from local to standardized data elements, and provides links to bound value set for vocabulary validation.
Integration Engine Route & User Guide	PHAs can use these NMI-specific Rhapsody or Mirth channels as a starting point for implementation if they employ an integration engine; includes mapping and validation.
Message Evaluation and Testing Service (METS)	CDC provides the METS tool to PHAs and other messaging partners to test generated messages one by one. The METS tool allows PHAs to perform independent validation of messages before end-to-end testing.
Message Validation, Processing, and Provisioning System (MVPS)	CDC uses MVPS to receive and process case notification messages from PHAs and provision them to CDC programs. PHAs and other messaging partners have access to the MVPS Dashboard, which provides feedback on messages received and information on any warnings or errors generated. CDC offers PHAs information and training on how to access and use the MVPS Dashboard.
MMG Test Scenarios	MMG test scenarios provide information the PHA needs to create test messages for validation.
MMG Test Messages	MMG test messages are helpful for testing the integration engine route and for comparing to PHA-created test messages.
MMG	An NNDSS HL7 MMG outlines the required, preferred, and optional fields for a valid case notification message for a given condition. This information is incorporated into the NMI Implementation Template. Draft MMGs are posted to the CDC website, along with associated artifacts. More information on new MMGs and sending case notification messages using HL7 can be found at https://wwwn.cdc.gov/nndss/case-notification/related-documentation.html. Outlines the required, preferred and optional fields for a valid case notification message for a given condition. This information is incorporated into the NMI Implementation Template.
National Notifiable Diseases Surveillance System (NNDSS)	The National Notifiable Diseases Surveillance System (NNDSS) is a nationwide collaboration that enables all levels of public health—local, state, territorial, federal, and international—to share notifiable disease-related health information. Public health uses this information to monitor, control, and prevent the occurrence and spread of state-reportable and nationally notifiable infectious and noninfectious diseases and conditions. NNDSS is a multifaceted program that includes the surveillance system for collection, analysis, and sharing of health data. It also includes policies, laws, electronic messaging standards, people, partners, information systems, processes, and resources at the local, state, territorial, and national levels.
National Electronic Disease Surveillance System (NEDSS)	Integrated surveillance information systems in reporting jurisdictions that are based on the National Electronic Disease Surveillance System (NEDSS) architectural standards are primary data sources for NNDSS. Jurisdictions use these information systems to create and send standards-based case notifications to CDC for NNDSS. Currently, case notifications can be sent using three different standards; CDC’s NNDSS Modernization Initiative will provide a single, new standard to transmit data to CDC.
NEDSS Base System (NBS)	The NEDSS Base System is a CDC-developed integrated information system that helps local, state, and territorial public health departments manage reportable disease data and send notifiable disease data to CDC. NBS provides a tool to support the public health investigation workflow and to process, analyze, and share disease-related health information. NBS also provides reporting jurisdictions with a NEDSS-compatible information system to transfer epidemiologic, laboratory, and clinical data efficiently and securely over the Internet.
National Electronic Telecommunications System for Surveillance (NETSS)	Before implementing NEDSS, CDC developed and used the National Electronic Telecommunications System for Surveillance. The term NETSS refers to a 1) computerized public health surveillance information system that provides CDC with weekly data regarding nationally notifiable diseases and 2) data file content format for submitting case notifications to CDC. NETSS surveillance information systems continue to be used by selected jurisdictions that are transitioning to the more robust NEDSS. A bare-bones approach for providing basic data and information, the NETSS file content format has not been changed or updated substantially since NETSS launched in 1990.
PHIN Case Notification Guide	The PHIN Case Notification Guide outlines the specifications for case notification messaging. This information is incorporated into the NMI Implementation Template.
