The NEDSS Base System (NBS) is an electronic disease reporting and case management platform supported by the Centers for Disease Control and Prevention. On January 1, 2019, the Infectious Disease Epidemiology & Prevention, Tuberculosis, Sexually Transmitted Infections, and Viral Hepatitis programs at the Indiana Department of Health (IDOH) transitioned their individual electronic disease surveillance and monitoring systems to NBS.
If you are a public health nurse, infection preventionist, or other local health department or hospital staff in need of NBS access, please contact your District Field Epidemiologist for instructions on how to request an NBS account.
NBS Updates
Beginning October 1st, NBS training will be required before access is granted for all accounts created on or after October 1, 2025. See below for the training requirements by role.
Training Requirements
Public Health Nurses (PHNs) and Other Local Health Department Users:
- NBS Training for Local Health Department Users (self-guided training series)
- Live training provided by the district's Field Epidemiologist
- Lead, TB/LTBI, and/or STI investigation training (if applicable)
Infection Preventionists (IPs) and Other Healthcare Users:
- NBS Training for Healthcare Users (self-guided training series)
Separate training requirements for DIS and other NBS users working exclusively with HIV/STI investigations will continue to be maintained by IDOH’s Division of HIV/STI/Viral Hepatitis.
The courses on IN-TRAIN are available to existing NBS users to review material at any time but will only be required for new users who submit their NBS access request on or after October 1st, 2025.
In our ongoing efforts to improve data security and privacy, changes to access in NBS for healthcare providers and local health department went into effect on February 17, 2025. Additional information about this decision can be found here.
Morbidity Reports
Hospital/healthcare providers will no longer be able to view or edit their submissions or submissions of users at their facilities. For MPOX and STIs, LHD users will only be able to create morbidity reports and will not be able to view or edit the reports after submission.
Reports
Hospital/healthcare providers will no longer be able to run reports to extract data from NBS.
LTBI
Hospital/healthcare providers will now submit LTBI as a morbidity report instead of an investigation.
The LTBI workflow in NBS will remain similar for PHNs, but IDOH will now notify PHNs to review the submitted morbidity reports and open an investigation. PHNs will be responsible for completing all required investigation fields, attaching the CXR, and submitting the notification to IDOH. Once medication is received, PHNs will complete the overall therapy completion information, confirm the case status, and set the investigation status to closed.
