About once a week in Cook County, an infant dies during sleep.

2020 - 2021

One in 4 sleep-related infants deaths were due to suffocation.

In Cook County today, the greatest threat to the lives of infants ages 1 month to 1 year is SUID. These deaths are almost always related to sleeping in an unsafe sleep situation. At RUSH, we lead the SUID Case Registry and Prevention for Cook County, and are committed to help you keep your infant safe by providing the guidance and resources you need to create a safe sleep environment.

Partnering for prevention

Preventing SUID starts with sharing what we've learned

Community Partnership Approaches for Safe Sleep — Chicago (CPASS Chicago) starts conversations about SUID and safe sleep with parents and those who support them. We create a safe place to openly talk about what gets in the way of safe sleep — the real circumstances that affect families every day. We listen and share what we know about SUID in our communities, empowering parents to lead the way to safer sleep. CPASS Chicago is the prevention arm of the Cook County SUID Case Registry and is housed at RUSH University Children's Hospital. Our partners are Family Focus, Chicago Birthworks Collective, Proviso Township Ministerial Alliance Network and Sinai Community Institute. We share a desire to help raise awareness about SUID. We believe that the more we talk about it, the more we learn about it and unlock new ways to prevent SUID. CPASS Chicago joins trusted community partners to share safe sleep guidance and resources at fairs, events, parent groups and more. If you would like CPASS Chicago to join an event in your community, please contact our prevention coordinator Felicia Clark at feliciaclark798@yahoo.com.

In 2009, the Centers for Disease Control and Prevention began funding work across the U.S. to collect detailed information on the circumstances of these deaths to help prevent them. In 2019, this work began in Cook County, and this report details Cook County’s 2020-21 SUID data to inform communities, providers and families of this public health threat to infants and to encourage potential prevention strategies.
