SUIDI Reporting Form

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.
