RECURRENCE OF UNEXPECTED INFANT DEATH

Families which had experienced two or more unexpected infant deaths we re the subject of detailed confidential enquiries, including necropsy examination. Cases were derived from two main sources: first, deaths o ccurring during a nationwide programme of support for families with a subsequent baby (8 families) plus 2 families from a series of confiden tial enquiries in Sheffield, and second, direct referrals from paediat ricians (17 families). Fifty-seven deaths were studied. Twenty-four fa milies had experienced 2 and three had experienced 3 deaths: 11 deaths (19%) were found to be adequately explained by history or post-mortem findings; 7 (12%) were probably accidental; 31 (55%) were most probab ly due to an action by one of the parents (filicide); only 5 (9%) were considered to be true or idiopathic sudden infant death syndrome; in 3 (5%) cases there was insufficient information to draw a conclusion. Five (18%) of the families lived in circumstances of serious social de privation. A history of psychiatric illness was present in one or both parents in 18 (67%) of the families.
