An analysis of the autopsies ordered by the Viennese Forensic and Health Authorities between 1967 and 1976 has shown that 2.3% of all suicides were committed in hospitals. Two thirds of the 77 examined cases were carried out by males. Thirty-five patients were in stationary psychiatric treatment; their average age was 50.7 years. In all other kinds of hospitals 42 (mostly male) patients committed suicide at an average age of 65.3 years. Preferred methods of performance were jump and fall from height (44.1%) and hanging (40.3%). Rare methods used were one case of abdominal incisions (harakiri), one self-strangulation, and one case of suffociation in plastic bags. The act was usually accomplished early in the morning or in the late afternoon. Among the suicidal patients who were hospitalized because of organic diseases those with malignant neoplasms [18] and cardiovascular diseases [12] were predominant. Also taking the suicides outside hospitals into consideration the numerical ratio between natural deaths due to cancer and the suicides of cancer patients is about 1:1,000. Amont the suicides in psychiatric institutions schizophrenics [11] and endogenous depressives [7] were the most numerous. In 4 cases the suicide was preceded by acts of injury or homicide.
