Risk of suicide after attempted suicide in the population of Slovenia from 1970 to 1996.
OBJECTIVE
All suicide attempts cannot predict suicide, therefore we examined those characteristics of suicide attempt which could most accurately predict completed suicide.


METHODS
Subjects were all individuals registered as committed suicides (N=16,522) or attempted suicides (N=15,057) in the register of suicides of the Republic of Slovenia between 1970 and 1996. Log linear analysis of a frequency table was used to uncover relationship between categorical variables.


RESULTS
The model we found fit between variables: mode, number of repetitions and type, then between number of repetitions, type and gender, and between mode, type and gender.


CONCLUSIONS
The risk of suicide in those who previously attempted suicide is approximately 773 times higher than the risk of suicide without a previous suicide attempt. Those who attempt suicide by hanging (hanging being in Slovenia the most frequent mode of completed suicide) are at even greater risk to commit suicide.


CONCLUSIONS
Our data suggests that clinicians should heighten their awareness that any suicide attempt can in some 20% predict suicide. Someone who has attempted suicide by hanging is at the highest risk of suicide.
