NMI Notes

Overall Updates

NNDSS Annual Data Reconciliation

• 2019 Data:
  • CDC closed the NNDSS database for updates to 2019 data on 12/10/20.
• 2020 Data:
  • CDC recognizes the demands of the pandemic on jurisdictions and CDC resources; therefore, the timeline for the reconciliation of the 2020 data is delayed, compared to a non-pandemic year.
  • Data reconciliation will be done using the Message Validation, Processing, and Provisioning System (MVPS) Portal.
    • Jurisdictions will view and extract the line list and aggregate tables from MVPS for all NNDSS case notification methods (HL7, National Electronic Telecommunications System for Surveillance [NETSS], NEDSS Base System [NBS] master message).
    • Jurisdictions can work at their own pace (but must still meet the established deadline).
    • State Epidemiologist sign-off process will be in MVPS.
  • Timeline:
    • June 2021: Jurisdictions receive training and have access to line lists and aggregate tables in MVPS.
    • September 30, 2021: Jurisdiction deadline for sign-off on final data.

COVID-19 Case Surveillance Resources Available on NNDSS Webpage

• The updated coronavirus disease 2019 (COVID-19) case definition is available on the NNDSS Surveillance Case Definitions webpage.

• The COVID-19 message mapping guide (MMG) is available on the NNDSS Technical Resource Center. For those interested in implementing the COVID-19 MMG, please email the CDC Electronic Data Exchange mailbox at edx@cdc.gov.
• Case notifications for multisystem inflammatory syndrome (MIS) associated with COVID-19 must be initiated in NNDSS. Use event code 11066. If a person meets the COVID-19 case definition and the MIS associated with COVID-19 case definition, CDC should receive separate case notifications for each condition using different Local Record IDs or NETSS Case IDs for each.

• For those interested in implementing the COVID-19 MMG, please email the CDC Electronic Data Exchange mailbox at edx@cdc.gov.

Core Requested Data Elements for COVID-19

• Due to the current high volume of cases, CDC is asking its state and local surveillance partners to focus efforts on a core set of data elements for COVID-19 case notifications, all of which can be sent using the generic v2 message.
• These data elements are based on information likely to be available from electronic laboratory reporting. CDC is asking states to focus on these core data elements but encourages states to send more as their resources allow. (For a list of data elements, please see slide 11 in the August 18 eSHARE presentation.)
• Jurisdictions are encouraged to send this information using the generic v2 message but may continue to use the legacy NNDSS messages or the CSV file upload to DCIPHER. For those interested in initiating generic v2 messages for COVID-19 and MIS associated with COVID-19, please email the CDC Electronic Data Exchange mailbox at edx@cdc.gov.
• This does not change or reduce the data that state, territorial, and local jurisdictions choose to collect on their own for surveillance, public health investigations, or contact tracing.
• As resources allow, jurisdictions are encouraged to send additional case information through the CSV upload to DCIPHER or through the COVID-19 MMG.

COVID-19 Vaccination Information

• CDC encourages jurisdictions to send vaccine history information in coronavirus disease 2019 (COVID-19) case notifications using these options:
• full COVID-19 message mapping guide (MMG),
• generic v2 MMG plus vaccine history from COVID-19 MMG, or
• DCIPHER/HHS Protect CSV upload using the updated January 2021 CSV template.
• Find resources at the NNDSS Technical Resource Center.

COVID-19 Value Sets Updated

• CDC reminds jurisdictions to update their COVID-19 case notification value sets. CDC expects frequent updates for certain value sets.
• Updated value sets include:
• PHVS_VaccineType_NND,
• Manufacturers of Vaccines (MVX), and
• PHVS_LabTestType_COVID-19.

NNDSS eSHARE Updates

• The next NNDSS eSHARE session is scheduled for Tuesday, 2/23/21, from 3:00 to 4:00 PM ET. The February eSHARE topic will be “NNDSS Data Processing Redesign and Hot Topic: Vaccine History in Case Notifications.”
• Access past eSHARE presentations at the NNDSS eSHARE website.

Join a Cohort to Jumpstart Your MMG Implementations!

• The NNDSS Association of Public Health Laboratories Technical Assistance team provides technical assistance to help groups, or cohorts, of public health agencies build and implement NNDSS HL7 case notification messages.
• Cohorts of 4–6 public health agencies focusing on the generic v2 and the COVID MMGs have been established.
• APHL and NBS subject matter experts guide participants through planning, gap analysis, data extraction, HL7 message creation, and validation. At completion, public health agencies will be ready to begin onboarding.
• For those interested in joining a cohort, please email the CDC Electronic Data Exchange mailbox at edx@cdc.gov.
