What this trial studies

This observational study assesses the safety of the SNOO Smart Sleeper Bassinet for infants at high risk for Sudden Unexpected Infant Death (SUID). It involves surveying 1000 caregivers of these infants to track the occurrence of serious injuries or deaths associated with the use of the SNOO. Participants will complete an electronic eligibility screening and follow-up surveys to report any adverse events over a six-month period. The study aims to gather data on usage patterns and outcomes related to the device.

Who should consider this trial

Good fit: Ideal candidates include primary caregivers of infants who are at high risk for SUID and have purchased or rented a SNOO Bassinet.

Not a fit: Patients who do not meet the high-risk criteria for SUID or are not primary caregivers will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide critical safety data that may enhance the use of the SNOO Bassinet for protecting high-risk infants.

How similar studies have performed: While this study focuses on postmarket surveillance, similar studies evaluating infant sleep safety devices have shown promising results in improving safety outcomes.
