Non-fatal deliberate self-poisoning in Dublin's north inner city--an overview.

It is almost three decades since a survey of attempted suicide in Dublin City Hospitals was published. In 1962, 159 cases in the City of Dublin and Borough of Dun Laoghaire were studied and reported. Over a six month period (November 1989-April 1990) 147 cases of deliberate self-poisoning were admitted to the Mater Hospital, Dublin, of which 100 case notes were appropriate for examination. In 1973, a six month survey of attempted suicide was carried out at the Mater Hospital, Dublin where 38 patients were admitted following non-fatal deliberate self-poisoning. In our study, the female to male ratio was 2:1, 50% of cases took more than one drug type,, benzodiazepines being the most commonly ingested compound. Alarmingly over a quarter (28%) of females under 25 had overdosed on paracetamol either alone or in conjunction with other compounds. Alcohol was consumed in 46% of all cases. 40% of cases involved a past history of deliberate self-poisoning and 60% had a past history of psychiatric intervention. Our survey outlines current trends in deliberate self-poisoning in Dublin's North Inner City. We have compared our 1990 survey to the similar survey conducted by our unit seventeen years ago. Several characteristics remain unaltered. The number of overdoses has almost trebled. We have noted a sharp rise in unemployment, alcohol abuse and psychiatric history among female overdoses. We have noted the disturbing introduction of paracetamol overdose particularly among young females (25%). Finally we have documented the introduction of overdosing amongst the homeless population which did not exist in the 1973 survey, but which accounts for 12% of our survey.(ABSTRACT TRUNCATED AT 250 WORDS)
