Sudden Unexplained Infant Death Investigation
SUID (Sudden Unexpected Infant Death also known as sudden unexplained infant death): is defined as the sudden
and unexpected death of an infant in which the manner and cause of death are not immediately obvious prior to investigation.

SIDS (Sudden Infant Death Syndrome): Is defined as the sudden death of an infant under one year of age which remains
unexplained after a thorough case investigation, including performance of a complete autopsy, examination of the death scene
and review of the clinical history. SIDS is a diagnosis of exclusion, assigned only once all known and possible causes of death
have been ruled out.

How are SUID and SIDS different? SUID can be caused by metabolic disorders, hypothermia or hyperthermia, neglect or
homicide, poisoning, or accidental suffocation. Some SUIDs are ruled SIDS, others are sleep-related deaths but ruled

Inaccurate classification of cause and manner of death hampers prevention efforts and researchers are unable to adequately
monitor national trends, identify risk factors, or evaluate intervention programs. We need valid and reliable data to support
research and prevention efforts if we want to reduce these infant deaths.

In 2003, CDC began leading the effort to revise the 1996 Sudden Unexplained Infant Death (SUID) Reporting Form and
Guidelines for the scene investigation, as well as actively educating and disseminating training materials on infant death scene
investigations to improve inaccurate classification of SUID in the United States. In 2004, CDC's Division of Reproductive Health
(DRH) and its partners implemented additional activities aimed at improving the accuracy and consistency of the reporting and
classification of SUID deaths. These activities included a planned effort to disseminate and promote the use of SUID
investigations tools and materials, and the development of a SUID case registry.

The Sudden Unexplained Infant Death Investigation (SUIDI) goals are to--

* Standardize and improve data collected at infant death scenes.
* Promote consistent diagnosis and reporting of cause and manner of death for SUID cases.
* Prevent SUIDs by using improved data to monitor trends and identify those at risk.
* Improve national reporting of SUID.
