Nov 16 -- The Centers for Disease Control and Prevention (CDC) invites comment on a proposed information collection project titled the National Death Index (NDI). The goal of NDI and the services it provides allows NCHS to collect mortality data to support epidemiological research and to furnish mortality information to approved public health and medical investigators. CDC must receive written comments on or before January 17, 2023.
The National Death Index (NDI) is a database containing identifying death record information submitted annually to NCHS by all the jurisdiction (states and territories) vital statistics offices, beginning with deaths in 1979. Searches against the NDI file provide the jurisdictions and dates of death, and the death certificate numbers of deceased study subjects.
Using the NDI Plus service, researchers have the option of also receiving cause of death information for deceased subjects, thus reducing the need to request copies of death certificates from the jurisdictions. The NDI Plus option currently provides the International Classification of Disease (ICD) codes for the underlying and multiple causes of death for the years 1979-2021. Health researchers must complete administrative forms in order to apply for NDI services, and submit records of study subjects for computer matching against the NDI file. A three-year Revision request is submitted to continue the use of the two administrative forms (the Application form and Transmittal form) utilized in the operation of the National Death Index (NDI) program, along with worksheets used to calculate related fees. These forms are submitted by NDI users when applying for use of the NDI and when actually using the service. In addition, this request includes the electronic versions that replace the three paper documents, one of which will include a minor reduction in the number of data collection items.
