The search of records by the local men- tal health service for the National Confi- dential Inquiry determined that 91 of the 219 persons who died by suicide (42%) were in contact with its service during the year before their death. Surprisingly, more of those receiving an open verdict than of those receiving a suicide verdict had made contact with local mental health services in the preceding year (Table 2). People whose death was due to multiple injuries or to poisoning by ingestion were particu- larly likely to have made contact with the mental health services in the last year, while few of those who died by toxic fumes or by unusual methods had been in contact (Table 2).(Table2).
