Abstract

Objective
This study aimed to identify the utility of risk-rescue rating scale (RRRS), a psychological scale, and certain biomarkers in determining the disposition of patients visiting the emergency department (ED) after their suicide attempts.
Methods
We retrospectively reviewed the medical records of patients who visited the ED after attempting suicide. The patients were classified into three groups for comparison: the discharged (DC) group, the general ward (GW) admission group, and the intensive care unit (ICU) admission group.
Results
This study included 454 patients, with 344 patients in the DC group (75.8%), 63 patients in the GW admission group (13.9%), and 47 patients in the ICU admission group (10.3%). The three groups showed statistically significant differences in age, time of visit, physical status, presumptive diagnosis, the RRRS, mental status, C-reactive protein, neutrophil-lymphocyte ratio (NLR), and systemic immune inflammation index. Multivariate logistic regression analysis showed that predictors of the GW admission included the time of visit, mental status, and the RRRS. A receiver operating characteristic curve analysis of RRRS for the decision to admit to GW and ICU showed a cut-off value of 36.5 and 44.5, respectively. However, no inflammatory biomarkers were identified as factors predicting GW and ICU admissions.
Conclusion
The RRRS is useful in determining the disposition of patients who visited the ED after suicide attempts.
