Classification of sleep-related sudden unexpected death in infancy: A national survey

Area of Science:

• Pediatrics
• Forensic Pathology
• Public Health

Background:

• Sudden Unexpected Death in Infancy (SUDI) investigations require accurate cause of death classification.
• Child Death Overview Panels (CDOPs) and paediatric pathologists play crucial roles in determining infant mortality causes.
• National guidelines exist for SUDI investigations, but compliance and consistency are key concerns.

Purpose of the Study:

• To assess how British CDOPs and paediatric pathologists classify causes of sleep-related SUDI.
• To evaluate adherence to national requirements for SUDI investigations.

Main Methods:

• An electronic survey was distributed to CDOPs and paediatric pathologists across the UK.
• Three case vignettes were used: accidental asphyxia, typical Sudden Infant Death Syndrome (SIDS), and SIDS with co-sleeping.
• Responses were analyzed to determine agreement on cause of death and classification terms.

Main Results:

• Low response rates from both CDOPs (41%) and pathologists (14%).
• Significant variation in agreement on cause of death across vignettes, particularly for SIDS with co-sleeping (34% CDOPs, 8% pathologists).
• Underuse of specific terms like SIDS and accidental asphyxia was noted; SUDI or unascertained were frequently used.
• Less than half (46%) of CDOPs reported >75% compliance with investigation guidelines.

Conclusions:

• There is considerable inconsistency in how sleep-related infant deaths are classified by CDOPs and pathologists.
• Limited agreement on cause of death classification highlights potential issues in SUDI investigation and reporting.
• The findings suggest a need for improved standardization and training to ensure accurate and consistent classification of infant sleep-related deaths.
