Can the Edinburgh Risk of Repetition Scale Predict Repetition of Deliberate Self‐poisoning in an Australian Clinical Setting?

This study tested the ability of the Edinburgh Risk of Repetition Scale (ERRS) to identify patients at high risk for repeat deliberate self-poisoning (DSP). Consecutive DSP patients (N= 1,317) over a 3-year period were followed-up for 12 months. A statistically significant relationship between ERRS scores and repetition was observed; however, sensitivity and specificity were low. Logistic regression analysis revealed only "previous parasuicide" contributed significantly to repetition. The ERRS had limited value in identifying patients at high risk of repeat DSP in this clinical population.     

Modifiable risk factors for attempted suicide in Australian clinical and community samples

Modifiable risk factors for suicide attempt require identification in clinical and community samples. The aim of this study was to determine if similar social and psychiatric factors are associated with suicide attempts in community and clinical settings and whether the magnitude of effect is greater in clinical populations. Two case-control studies were used: nationwide community-based lifetime attempted suicide (ComAS) cases compared to nationwide community controls; and clinical deliberate self-poisoning (ClinDSP) cases that had hospital treatment compared to normative controls of similar demographic composition. The pattern of risk factors in ComAS and ClinDSP cases was similar, the magnitude of risk usually greater in clinical cases. Greatest attributable fractions were: ComAS current unemployment (39.8% male, 15.5% female) and anxiety disorders (14.0% males, 22.6% females); and ClinDSP current unemployment (69.6% male, 55.5% female) and affective disorders (45.4% male, 39.1% female). Practical intervention targets were unemployment, anxiety and substance use disorders, affective disorders (clinical only), and personality disorder (females only).
