The analysis of the use of 'unascertained' for sudden unexpected deaths in infancy from 1988 to 2010

摘要

In England and Wales, the rate of sudden infant death syndrome (SIDS) has had a near eightfold decline, from 2.3 deaths per 1000 live births in 1988 to 0.3 in 2009. Most of this decline can be attributed to the 'back to sleep' campaign in 1991 which led to a 75% drop. From 1995, part of this fall could be attributed to the introduction of the classification of some deaths as 'unascertained'. This has led to concerns being raised.
