Steps for identifying unreported infant deaths
Steps for Identifying Unreported Infant Deaths 2006-2007

  • Identify all infants with birth weights <750 gms

    • Determine whether death certificate was filed

    • If not, follow up with hospital to determine infant status

  • Follow up on infants with fatal diseases (e.g., anencephaly) to ensure death certificates were filed

  • Match hospital discharge records with birth records to identify unreported infant deaths

  • Provide training and guidelines for hospital staff on how to report vital events

    • Flow chart is a useful tool

  • Review out of state data for potential problems; follow up with other states as needed

Guidelines for Reporting Live Births, Infant Deaths, 2006-2007

Fetal Deaths, and Induced Terminations of Pregnancy

(i.e., breathe or show any other evidence of

life, such as beating of the heart, pulsation of

the umbilical cord or definite movement of

voluntary muscle, whether or not the umbilical

cord has been cut or the placenta is attached)

Did the infant/fetus

show signs of life

at time of delivery?



(Purposeful interruption of an intrauterine

pregnancy with the intention other than to

produce a live born infant and which does not

result in a live birth. Excludes management

of prolonged retention of products of conception

following fetal death)

Is the infant

still living?

Life Expectancy Impact Due to Exclusion of Military Deaths 2006-2007


  • Initial study on the effect of overseas World War II deaths on U.S. life

  • expectancy

  • - literature is thin on the subject of military death impacts

  • - the perfect dissertation topic?

  • - affects, negatively, both numbers of deaths and population that

  • feed into impacted death rates

  • Source located for the number of World War II deaths

  • - some modeling may be required for inputs into life tables

  • - Two aspects being consider: registration and mortality measure impacts

Background research data requests

  • NAPHSIS Resolution established a process for NAPHSIS review of requests that NCHS receives to provide birth and death data to government agencies and researchers.

  • The goal of this process is to expedite review for requests for access to state data from researchers and reduce the burden on states and researchers while adhering to state laws for data release.

Methods research data requests

  • Internet based survey was sent to all states covering the following topics:

    • Allowing NAPHSIS to act on states behalf in approving:

      • the release of birth data

      • death data

      • birth certificate numbers

      • death certificate numbers,

    • Data items that are prohibited from release due to laws, regulations or other legal requirements

Summary of NAPHSIS-NCHS Reviews Certificate #

  • Request for data from linked birth-infant death file: Not reviewed—data not available

  • EPA: 4 studies using individual-level 2001-2006 demographic and medical mortality data with all counties and exact dates of death identified. Data to be made available to one EPA federal employee and three EPA university grantees for the study of mortality risks associated with ambient exposure to air pollution: Approved

  • Duke University Study of extreme aged project: to obtain mortality data and certificate numbers for all death certificates since 1960 of male decedents who survived to age 105 or more and female decedents who survived to age 108 or more to address the overall question of why the U.S. may enjoy lower mortality for the “oldest-old” than many other developed countries. Also to explore the possibility of adding data to the International Database on Longevity (IDL). Approved

Summary of NAPHSIS-NCHS Reviews Certificate #

  • SSA-NDI Project to assess the completeness and accuracy of Social Security Numbers (SSNs) reported on state death certificates and included in the National Death Index (NDI) by matching selected certificates to death records held by the SSA. Involves releasing selected NDI records to SSA for matching selected certificates to death records held by the SSA. NDI records with invalid, missing or unverified SSNs. NDI records would be evaluated for accuracy and completeness and wherever possible an alias NDI record would containing the correct SSNs would be created. NCHS proposes to include these alias records in the NDI master file. Approved

  • University of Pennsylvania Project to conduct Motor Vehicle Crash (MVC) research using the linked Fatality Analysis Reporting System (FARS) and Multiple Cause of Death (MCOD) files for 1987-2004 in the NCHS Research Data Center (RDC). This is a request to extend approved pediatric analyses to adults. Approved

Summary of NAPHSIS-NCHS Reviews Certificate #

  • National Longitudinal Mortality StudyThis is a continuation project by NCHS to update its evaluation of the quality of Hispanic origin, race, and other mortality data. This has been done by comparing self-reported Hispanic origin, race, and other variables on the Current Population Survey (CPS) with State-coded Hispanic origin, race, and other variables on the death certificate during 1986-1998 and will be updated for 1999-2002. Quantitative measures will be produced to evaluate the comparisons at the national and state level. These measures will be available to the States. Approved

Other potential activities
Other Potential Activities Certificate #

  • Promote the use and extension of WDQS at the state level

  • Explore statistical issues such as consistent models for trend analysis and data linkage methodologies

  • Begin standards development work

  • Explore partnering with other entities such as the March of Dimes on issues of mutual research interest
