Objective：The aim of this study was to analyze the clinical characteristics of individuals who used alcohol at the time of attempting suicide.
Methods：We divided 143 individuals who attempted suicide by consuming drugs into two groups on the basis of their blood alcohol concentration level: drinker group(n=79) and non-drinker group(n=64). We compared epidemio￢logical characteristics and suicidal behavior between the groups by using the Suicidal Intent Scale(SIS) and the Risk Rescue Rating Scale(RRRS). In addition, we administered the Glasgow Coma Scale(GCS) and the Acute Physiology and Chronic Health Evaluation-II(APACHE-II) to evaluate the medical lethality of the individuals who attempted sui￢cide. We used Student’s t-test, Pearson’s correlation analysis, and multiple linear regression to analyze the data.
Results：The drinker group scored lower on the SIS’s planning subscale than the non-drinker group did(p=0.022). The drinker group’s blood alcohol concentration levels were negatively correlated with the rescue potential of their suicidal attempt(p=0.031) and the APACHE-II score(p=0.003). Higher blood alcohol concentration levels predicted poorer medical outcomes measured by the APACHE-II(p=0.004).
Conclusion：Our findings support the notion that alcohol use increases suicidal impulsivity, decreases rescue po￢tential, and worsens medical outcomes. Therefore, suicide prevention programs need to include education and counseling about the risks associated with alcohol use.
