Almost a quarter of Queensland's sudden and unexpected deaths in infancy (SUDI) happen in families known to the child protection system, with many occurring in hazardous sleep environments, new research shows.
Of the 661 cases of SUDI registered in Queensland in the 16 years between 2004 and 2019, about 24 per cent involved families known to the Department of Children, according to a report prepared for the state's Child Death Review Board.
