The Centers for Disease Control and Prevention’s Division of Reproductive Health supports Sudden Unexpected Infant Death (SUID) monitoring programs in 32 states and jurisdictions, covering about 2 in 5 SUID cases in the United States. The SUID Case Registry builds on local child death review programs and uses the National Center for Fatality Review and Prevention’s Case Reporting System to compile information about the circumstances associated with SUID cases as well as information about investigations into these deaths. Participating states and jurisdictions use data about SUID trends and circumstances to develop strategies to prevent future fatalities.

The SUID Case Registry first began in Michigan in 2010. Since that time, data has been gathered on all sleep-related infant deaths in each of the 83 counties in the state. In Michigan, sleep-related infant deaths are defined as deaths to infants less than 1 year of age that occur suddenly and unexpectedly due to:

• Suffocation/Positional Asphyxia;
• Sudden Infant Death Syndrome (SIDS);
• Undetermined/Sudden Unexpected Infant Death (SUID); and
• Other causes when the sleep environment was likely to have contributed to the death.

Michigan’s SUID Case Registry is housed within the Center for Child and Family Health at MPHI.
