최초 자살시도 방법으로 중독을 선택한 환자의 임상적 특성: 물리적 자해 방법을 사용한 환자와의 비교

Abstract

Purpose: This study was conducted to compare the characteristics of first suicide attempt patients with self-poisoning with those of self-injured patients. Methods: In this retrospective data analysis, data were collected from emergency department patients who made a first suicide attempt between October 2013 and January 2017. Data included demographic, socioeconomic, physical and mental health status, method of suicide attempt, and authenticity of suicide intent. Patients were classified into a self-poisoning and self-injury group. Results: Among 2,252 patients, 788 patients were making their first suicide attempt. Of these patients, 443 were self-poisoning patients. Males were less common among the self-poisoning group. Cohabitants (303 [89.4%] vs. 193 [81.4%]; p=0.010), married state (214 [57.4%] vs. 108 [41.2%]; p<0.001), and asking for help after suicide attempt (136 [86.1%] vs. 103 [73.6%]; p=0.009) was more common in the self-poisoning group than the self-injury group. However, planned suicide attempt was more frequent in the self-injury group (26 [16.0%] vs. 9 [4.7%]; p=0.001). Moreover, authenticity of suicide intent was higher in the self-injury group (12 [11.3%] vs. 42 [40.4%]; p<0.001). Conclusion: In the self-poisoning group, there was a higher rate of females, married people, existing cohabitants, and tendency to ask for help after suicide attempt. There were also more impulsive suicide attempts in this group. The results presented herein will help prevent self-poisoning suicide attempts among high risk patients.
