“…The findings of this study demonstrated that the methods of suicide attempt had an effect on the need for hospitalisation. Among the OECD countries, South Korea has the highest suicide rate, which is two times higher than that in the United States [ 22 ]. While suicide ranks as the 13th leading cause of life lost with 800,000 deaths worldwide annually [ 23 ], it is the 5th leading cause of death in South Korea [ 24 ].…”

Background Suicide is a significant public health problem. Individuals are estimated to make up to 20 suicide attempts before suicide. The emergency department (ED) is the first location where individuals are brought after a suicide attempt. This study investigated the factors related to delays in the medical hospitalisation of patients who attempted suicide and aimed to provide criteria for hospitalisation decisions by physicians. Methods This study included patients who had deliberately self-harmed (age ≥ 19 years) and presented at the EDs of two tertiary teaching hospitals between March 2017 and April 2020. Those for whom relevant demographic and clinical information were unavailable and those admitted to the psychiatric wards were excluded. Results This study included 414 patients in the hospitalisation group and 1346 in the discharged group. The mean patient age was 50.3 ± 20.0 years and 40.7 ± 17.0 years in the hospitalised and discharged groups (p < 0.001), respectively. The mean ED length of stay (LOS) was 4.2 ± 12.3 and 11.4 ± 18.8 h in the hospitalised and discharged groups, respectively. In the hospitalised group, the odds ratio and confidence interval for aged 35 ~ 64 (2.222, 1.343–3.678), aged over 65 (2.788, 1.416–5.492), sex -male (2.041, 1.302–3.119), and consciousness (1.840, 1.253–2.466). The Risk-Rescue Ratio Scale (RRRS) was (1.298, 1.255–1.343). A receiver operating characteristics analysis of RRRS for the decision to hospitalise patients who attempted suicide showed a cut-off value of 42, with sensitivity, specificity, and area under the curve being 85.7, 85.5%, and 0.924, respectively. Conclusion The level of consciousness and the RRRS of patients who attempted suicide can be the factors to decide medical hospitalisation and reduce ED LOS and crowding.

Background Suicide attempters contribute to a significant public health problem. Individuals are estimated to make up to 20 suicide attempts before committing suicide. The emergency department (ED) is the first location where suicide attempters are brought. This study investigated the factors associated with early hospitalization decisions to determine the criteria for patient hospitalization rather than psychiatric ward admission and identify measures to shorten ED length of stay (LOS). Methods This study included suicide attempters (age ≥19 years) who visited the EDs at two tertiary teaching hospitals between March 2017 and April 2020. Results A total of 414 in the hospitalization and 1,346 in the discharge groups patients were included. The mean age was 50.3 ± 20.0 years and 40.7 ± 17.0 years in the hospitalization and discharge groups (p <0.001). The mean ED LOS was 4.2 ± 12.3 and 11.4 ± 18.8 h in the hospitalization and discharge groups, respectively. In the hospitalization group, the odds ratio and confidence interval for age (1.017, 1.008–1.026), sex (male) (1.787, 1.127–2.515), consciousness (2.330, 1.653–3.266), and the Risk-Rescue Ratio Scale (RRRS) (1.273, 1.242–1.304) were calculated. A receiver operating characteristics analysis of RRRS for the decision to hospitalize suicide attempters showed a cut-off value of 42, with sensitivity, specificity, and area under the curve of 85.7%, 85.5%, and 0.924, respectively.Conclusion For suicidal attempters in the ED, the decision on medical hospitalization rather than psychiatric admission should be based on their level of consciousness and the RRRS to reduce ED LOS and crowding.

Cross-national comparisons of increasing suicidal mortality rates for Koreans in the Republic of Korea and Korean Americans in the USA, 2003–2012

Abstract: Suicide in Korean Americans is higher than for other Asian Americans and follows temporal patterns more similar to Korea than the USA. Interventions to prevent suicide in Korean American populations, particularly among the elderly, are needed.
