Which deliberate self-poisoning patients are most likely to make high-lethality suicide attempts?

Oh SH, Kim HJ, Kim SH, Kim YM, Park KN - Int J Ment Health Syst (2015)

Bottom Line: The high-risk group consisted of patients with 11-15 risk points, whereas patients in the low-rescue group had 5-11 risk points.Pearson's correlation analysis showed that the total risk score for patients with DSP was negatively associated with the total rescue score (r = -0.201, p < 0.001).Of the total number of DSP patients, 42 were included in the high-risk/low-rescue group.

ABSTRACT

Background: The risk/rescue rating scale (RRRS) assesses the lethality of a suicide attempt, which is defined as the probability of inflicting irreversible damage. We assessed the lethality of suicide attempts using the RRRS and identified the socio-demographic profiles of patients who achieved high lethality in deliberate self-poisoning (DSP).

Methods: A retrospective study was conducted to evaluate DSP patients who visited the emergency department of a tertiary teaching hospital between 2000 and 2011. The data included socio-demographic information, clinical variables, risk factors (e.g., the method used, whether consciousness was impaired, toxicity, reversibility and whether treatment was required) and rescue factors (e.g., location, who initiated the rescue, the probability of discovery, the accessibility of rescue, and delay until discovery). The high-risk group consisted of patients with 11-15 risk points, whereas patients in the low-rescue group had 5-11 risk points. We examined the characteristics of high-lethality suicide attempts (high-risk/low-rescue group).

Results: A total of 1114 patients were enrolled in this study. Pearson's correlation analysis showed that the total risk score for patients with DSP was negatively associated with the total rescue score (r = -0.201, p < 0.001). Of the total number of DSP patients, 42 were included in the high-risk/low-rescue group. The multivariate logistic regression analyses showed significant associations between high-lethality suicide attempts and male gender (OR 2.70, 95 % CI 1.41-5.18, p = 0.003), older age (OR 1.02, 95 % CI 1.01-1.04, p = 0.015), and unemployment (OR 2.98, 95 % CI 1.41-6.33, p = 0.004).

Conclusion: This retrospective study demonstrates that male gender, advanced age, and unemployed status were associated with high-lethality suicide attempts in DSP patients.

Mentions: In the risk analysis, 156 patients were included in the high-risk group and 958 were included in the low-risk group (Table 3). The rate of death prior to discharge was significantly higher in the high-risk group than in the low-risk group (p < 0.001); only one patient in the low-risk group died prior to discharge. The average ages of the patients in the low-risk and high-risk groups were 35.48 ± 15.70 and 47.57 ± 19.20 years, respectively (p < 0.001). Male gender, previous suicide attempts, and unemployment were also significantly associated with high-risk suicide attempts (p < 0.001, p = 0.043, p < 0.001, respectively). Differences in living with family members, alcohol co-ingesting with DSP, and psychiatric history were not statistically significant between the two groups. In the logistic regression analyses, the high-risk group was significantly associated with male gender (OR 3.22, 95 % CI 2.21–4.69, p < 0.001), older age (OR 1.03, 95 % CI 1.02–1.04, p < 0.001), and unemployment (OR 1.77, 95 % CI 1.20–2.62, p = 0.004) (Fig. 2).Table 3
