SUIDI Reporting Form

Learn more about the Sudden Unexplained Infant Death Investigation Reporting Form (SUIDIRF), including its importance, the information it collects, and how to use the form.

In 1996, CDC released the original SUIDIRF. In 2006, CDC released a revised SUIDIRF.

The SUIDIRF Is Important for Several Reasons:

  • Standardizes data collection that may improve classification of sleep-related infant deaths. 
  • Assists in determining accurate cause of death by strengthening information about the circumstances of the death available before autopsy. 
  • Guides investigators through the steps involved in an investigation. 
  • Allows investigators to document their findings easily and consistently. 
  • Produces information that researchers can use to recognize new threats and risk factors for sudden unexpected infant death (SUID) and sudden infant death syndrome (SIDS).

The following information is collected on the SUIDIRF:

  • Investigation data.
  • Witness interview.
  • Infant’s medical history.
  • Infant’s dietary history.
  • Pregnancy history.
  • Incident scene investigation.
  • Investigation summary.
  • Investigation diagrams.
  • Summary for pathologist.

Using the SUIDI Additional Investigative Forms

While the additional investigative forms can be used in addition to the SUIDIRF to collect important investigative information, collecting this information before autopsy is not essential.
