OBJECTIVE: Numerous authors have reported serious shortcomings in the treatment of suicidal patients. This study examined the treatment suicide attempters admitted to a psychiatric hospital in Switzerland had received prior to the suicide attempt. METHOD: Thirty-one patients were admitted to this hospital within a year, representing 36 suicide attempts, which corresponds to 6.5% of the annual admission number. Three of these patients were admitted twice, and one patient was admitted three times. Information on previous treatment was collected in personal interviews and included medication, and its dosage, at 1 month and 2 weeks prior to the suicide attempt, and whether the patient had received psychotherapy. In addition, details of the psychosocial event and the means of the suicide attempt were recorded. RESULTS: Twenty-one patients had been prescribed psychotropic drugs in 24 events, but only in 17 events concerning 15 patients, antidepressants were prescribed prior to hospitalisation. Antipsychotics and benzodiazepines were prescribed in 6 and 21 events, respectively (including 8 events with hypnotics). None of the patients was treated with lithium. In 19 events, 16 patients had received psychotherapy prior to admission. In 32 events, psychotropic drugs were used for the suicide attempt. CONCLUSION: The findings confirm the undertreatment of patients attempting suicide reported by other authors. In spite of the majority of patients being under psychiatric care, no adequate pharmacotherapy had been prescribed particularly for depressed patients.
