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

The SUIDIRF is a voluntary tool and template for states and jurisdictions to use. In 1996, CDC released the original SUIDIRF. In 2006, CDC released a revised SUIDIRF and developed an infant death scene investigation training curriculum. In 2017, CDC worked with experts in death investigation to learn about their suggested updates for the form. In 2020 CDC released a revised version of the SUIDIRF that incorporated their suggestions.

The SUIDIRF:
  • Standardizes data collection to help 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 an 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 risk factors for sudden unexpected infant death (SUID) and sudden infant death syndrome (SIDS).
The following information is collected on the SUIDIRF:
  • Infant demographics.
  • Pregnancy history.
  • Infant history.
  • Incident scene investigation.
  • Incident circumstances.
  • Investigation summary.
  • Investigation diagrams.
  • Summary for pathologist.

Using the SUIDI Additional Investigative Forms

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