Publication Updates

The Quick Start Guide to Using the Access & Management Center Data Access Rules has been updated to describe changes to the user interface (e.g., how to delete/suspend rules, work with new data sources, and use optional fields to fine tune how rules are applied to users and groups). The quick start guide has just been posted on the NSSP Technical Resource Center’s Publications and Standards webpage. This refresh describes features added after AMC version 1.5.4.

With the adoption of RStudio Workbench, the Quick Start Guide to Using RStudio Pro is being updated to our user manual format as additional information and features are documented. This user manual is in review, and we anticipate that it will be published in late August 2022.

Mortality Data Update

NSSP’s use of mortality data is still in its infancy. NSSP health scientists are doing preliminary analyses such as comparing trends of health conditions (using ICD-10 codes only) with multiple data sources to get insight into how NSSP data compare with other mortality data sources. They are also looking at the timeliness of key fields (ICD-10 code and Literal Cause of Death) to understand when these fields are populated and the death records finalized.

Currently, six public health jurisdictions actively submit mortality data. Site personnel in these jurisdictions can view their mortality data in the Daily Site Processing Summary Reports. The reports for sites that do not submit data will include this section with a note that mortality data have not been received.

To learn more about onboarding your site’s mortality data, please contact NSSP at for assistance.

Onboarding is a Collaborative Process

The NSSP onboarding team will work with your health department, facility, vendor for electronic health records (EHR) or heath information exchange (HIE) to transmit syndromic surveillance data from internal medical record systems to the NSSP Biosense Platform. If you represent an HIE, EHR vendor, or hospital and want to participate in the NSSP, please contact

If you’re already an NSSP participant and need onboarding assistance, please contact the Service Desk.
