Analysis of risk factors affecting a suicidal attempter exposing suicidal intensions for the development of the active intervention strategy for suicide prevention

OBJECTIVE: This study examined the clinical characteristics of suicide attempters who exposed their suicidal intension to suggest an active intervention strategy for suicide prevention based on the regional emergency medical service system. METHODS: A prospective database of suicide attempters who visited the emergency department of Chungbuk National University Hospital between October 2013 and December 2017 was used. All of the adult patients who provided consent for the initial assessment for suicidal attempters were eligible, excluding cases with unknown exposure of suicidal intension. The primary and secondary endpoints were the risk factors affecting exposure to the suicidal intension and characteristics of the exposure group. The adjusted odds ratios (AORs) of exposure to suicidal attempts after adjusting for potential confounders was calculated. RESULTS: Of a total 1,035 suicidal attempters enrolled, 332 (32.1%) were included in the exposure group. The exposure group was more likely to have an educational level above high school and no religion, and have suicidal characteristics at night time (18:00–08:00), under the influence of alcohol, suicidal plan before 1 week, and suicidal method involving asphyxia (P<0.05). The exposure group was more likely to have no guardian (AORs, 1.46; 95% confidence interval [CI], 1.00–2.12), use methods involving asphyxia (AORs, 2.07; 95% CI, 1.46–2.91), and attempt suicide at night (18:00 to 08:00) (AORs, 1.38; 95% CI, 1.05–1.83) compared to the no exposure group. CONCLUSION: Models need to be established, where regional mental health welfare center, local government, fire headquarter, and tele-communication companies can participate in the implementation of an active intervention strategy.

Comparison of Injury Patterns and Severity between Younger and Older Rider in the Motorcycle Accident

PURPOSE: The mortality of motorcycle accidents in old age is very high in Korea compared with other countries. The aim of this study is to compare the differences in injury patterns and severity between younger and older riders in motorcycle accidents. METHODS: Cross sectional data from Konkuk University Chung-ju Hospital were used to evaluate patients who visited the emergency department as a result of a motorcycle accident from June 2012 to May 2014. We separated the patients into younger rider group from 16 to 64 and older rider group over 65 years of age. Injury sustained, the types of severe injuries and injury severity between two groups were compared using Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS). RESULTS: The younger and older rider group included 310 and 111 patients, respectively. Injuries in head, face, chest, and lumbar spine were higher in the older rider group (p<0.05). In the comparison of severe injury sustained over AIS 2, the older rider group had a four-fold odds increased rate of head injury (OR 3.718, 95% CI: 2.317-5.965, p<0.001) and a two-fold odds increased rate of chest injury (OR 2.306, 95% CI: 1.199-4.437, p=0.016) compared with the younger rider group. In addition, the older rider group had a nearly seven fold increased odds of severe injury over ISS 15 (OR 7.108, 95% CI: 3.579-14.119, p<0.001). CONCLUSION: In a motorcycle accident, the frequency of head, facial, chest, and lumbar injuries was higher in the older rider group. In addition, the older rider group had a higher injury severity, particularly a higher risk of head and chest injury.
