AbstractObjectives:To establish suicide rates of psychiatric inpatients in Ireland and the characteristics, demographic, social and medical, of the patients involved.Method:Clinical, post mortem and inquest data on all such deaths from 1983-1992 were examined. Suicide rates were calculated using ‘person year method’.Results:The suicide rate for short stay inpatients (stay less than one year) was 319/100,000, and 118/100,000 for long stay patients. The average duration of illness at time of suicide was 10 years. A fourfold increase in suicide rate of inpatients over the century was associated with a similar increase in the suicide rate in the general population. Thirty five per cent of suicides were aged 25-34 years. The risk of suicide was higher the shorter the time interval after admission. Three quarters of suicide deaths in registered inpatients occurred away from hospital grounds.Conclusions:Social factors which contribute to an increase in the suicide rate in the general population are relevant to the increase in hospital inpatient suicides. More effective and comprehensive services to meet the needs of those with severe mental illness, particularly young adults, are essential. The results emphasise the importance of managing inpatients in a safe, secure environment. The person year method is appropriate for monitoring changes in suicide rates.
