Comparison between Natives and Foreigners who Visited an Emergency Center due to Suicidal Attempt

PURPOSE: In an effort to determine the characteristics of foreign suicides who visit an emergency center, this study analyzed suicidal attempt between natives and foreigners. METHODS: We conducted a retrospective analysis of 1,218 Korean and 149 foreign suicidal attempters who visited a regional emergency center from January 1, 2009 to December 31, 2013. We compared two groups according to age, sex, selected suicidal methods, past psychiatric history, medical examination and treatment acceptance, elapsed time to visit an emergency center after suicidal attempt, emergency center residence time, and hospitalization period. RESULTS: No difference in medical exam acceptance and tetanus vaccination was observed between the two groups. However, we found a difference in hospitalization acceptance. The prevalence rate of psychiatric disorders was lower in foreign suicides, and the refusal rate of psychiatric treatment was higher in foreign patients. CONCLUSION: In foreign suicides, social support including finance is required for easy access to health care service. In addition, more active interdisciplinary cooperation with the department of psychiatry and close observation is needed.

Corrected QT Interval Differences from Intoxication by Over The Counter Versus Prescription Hypnotics

PURPOSE: This study analyzed QTc prolongation in patients intoxicated from over the counter (OTC) hypnotics compared with prescription hypnotics. METHODS: The medical records of intoxicated patients presented to four emergency centers from January 1, 2010 to December 31, 2010 were retrospectively reviewed. The records of hypnotics overdose patients were selected and investigated for several features: general characteristics, vital signs, past history, ECG findings, treatment methods, ED stay time, drug category and amount, and final results. RESULTS: There were 134 patient cases of OTC hypnotic intoxication (36.9+/-15.1yrs, M:F=37:97), and 270 patient cases of prescription hypnotic intoxication (47.9+/-18.1yrs, M:F=58:212). The ECG QTc upon emergency center admission was 468.4+/-34.8 msec in the OTC hypnotic intoxication group and 449.48+/-26.2 msec in the prescription hypnotic intoxication group (p<0.05). QTc prolongation was noted in 81.3% of patients in the OTC hypnotic intoxication group and 64.1% of patients in the prescription hypnotic intoxication group (p<0.05). CONCLUSION: ECG QTc prolongation was more common from OTC hypnotic intoxication than prescription hypnotics. Close monitoring is therefore recommended for patients who have ingested and overdosed from OTC hypnotics to prevent potentially lethal cardiac toxicity.
