Objectives:
:Cancer diagnosis causes significant distress while it may also bring positive change: post-traumatic growth. This study was conducted to analyze factors that affect post-traumatic growth.
Methods:
:Medical records of 52 cancer patients who received psychiatric treatment at a university hospital in Seoul were reviewed and the correlation between post-traumatic growth and following factors were analyzed: Resilience, Anxious thoughts and tendencies, Mindful attention awareness, Acceptance attitude
Results:
:Using Multiple Generalized Linear model, a positive correlation was found between post-traumatic growth and resilience (B=1.45, p<0.0001), mindful attention awareness (B=0.58, p=0.0030) and acceptance attitude (B=1.29, p=0.0003), while anxious thoughts and tendencies (B=-0.84, p<0.0001) had negative association.
Conclusions
:Factors that have a positive impact on post-traumatic growth were resilience, mindful attention awareness, acceptance attitude and a factor with a negative impact was anxious thoughts and tendencies; Factors that impact post-traumatic growth need to be taken into account, when approaching the treatment of cancer patients.

Objective:
To identify factors that affect the participation of female immigrants in their 20s in the national cervical cancer screening programs.
Methods:
Data were obtained from the National Health Insurance Services from 2016 to 2017. A total of 17,730 women who agreed to undergo cervical cancer screening during 2016-2017 were included in the study.
Results:
Of the 17,730 women, 8,149 (46%) participated in cervical cancer screening, whereas, 9,581 (54%) did not. Logistic regression analysis of factors related to cervical cancer screening showed that the odds ratio (OR) of screening was higher in short duration of stay (OR, 1.18; 95% confidence interval [CI], 1.03-1.35), Chinese nationality (OR, 1.43; 95% CI, 1.28-1.59), unemployment (OR, 1; 95% CI, reference), participation in general health screening (OR, 4.16; 95% CI, 3.24-5.33), and comorbidities (OR, 1.16; 95% CI, 1.09-1.24) when compared to the other populations. The highest OR was associated with participation in general health screening.
Conclusion
Appropriate programs should be developed to increase participation of socially vulnerable groups in cervical cancer screening. Such programs will improve awareness regarding cervical cancer screening and reduce disparities in healthcare.

Journal of the Korean Society of Emergency Medicine 2023;34(1):70-78
Objective:
Early identification of COVID-19 in patients is important to prevent significant worsening of the disease. This study was undertaken to verify whether MEWS (Modified Early Warning Score), NEWS(National Early Warning Score), ROX index, and CURB-65, which are early diagnostic tools for severe respiratory diseases, could be applied to patients visiting the emergency room for COVID-19.
Methods:
This retrospective observational study included patients who visited an emergency medical center from September 1 to October 31, 2020, and from January 1 to February 28, 2021. Based on the vital signs and blood tests during the emergency room visit, severity evaluation tools and early diagnostic tools for severe cases were used and compared according to their area under the curve (AUC) values. The primary outcome was in-hospital mortality, while the secondary outcomes were intensive care unit admission rate and the need for mechanical ventilation based on these four tools (MEWS, NEWS, ROX index, and CURB-65).
Results:
A total of 667 patients were analyzed. No significant difference was determined between the non-survivor group and survivor group in the MEWS values (P=0.13), but statistically significant differences were observed for NEWS (5 vs. 1, P<0.05), CURB-65 (2 vs. 1, P<0.05), and ROX index (16.61 vs. 23.1, P<0.01). The AUC value of NEWS for death prediction indicated a good predictive power at 0.80, while that of MEWS showed a low predictive power at 0.57, which was statistically significant. Moreover, the AUC values of CURB-65 and ROX index did not differ significantly from values obtained for NEWS.
Conclusion
As early diagnostic tools for predicting death in COVID-19 patients, NEWS, ROX index, and CURB-65 showed excellent discrimination ability, whereas MEWS showed statistically and significantly lower discrimination ability.

Journal of the Korean Society of Emergency Medicine 2023;34(3):241-248
Objective:
This study examined the characteristics of patients visiting the emergency department (ED) with fever after the chronification of the coronavirus disease 2019 (COVID-19) pandemic.
Methods:
This retrospective observational study analyzed the medical records of patients who visited the ED with fever from May 1 to October 31, 2021, and the corresponding period in 2019. This study was conducted at a single center in Seoul, Korea.
Results:
There was no statistical difference in the comorbidities of the patients of the two groups: the AC (after the COVID-19 pandemic) group and the BC (before the COVID-19 pandemic) group. As for the level of consciousness at the time of ED arrival, there was a significantly larger decrease in consciousness (verbal response or less) in the AC group than in the BC group (P=0.002). In the case of the National Early Warning Score (NEWS), the proportion was higher in the AC group in the moderate-risk and high-risk groups (P=0.003). The median time from symptom onset to ED arrival was 15.7 hours in the BC group and 13.8 hours in the AC group, and there was no significant difference (P=0.137). When leaving the ED, the AC group had a higher admission rate to the ward and intensive care unit than the BC group. There was no statistical difference in the in-hospital mortality between the two groups (2.9% and 2.4%, respectively; P=0.62).
Conclusion
Patients who visited the emergency room with fever after one year of the COVID-19 pandemic showed a similar time from symptom onset to ED arrival compared to patients who visited before the COVID-19 pandemic. In addition, there was no difference in in-hospital mortality among these patients compared to those with fever before the COVID-19 pandemic.

Journal of Korean Medical Science 2023;38(14):e106-
Background:
Recent reports have suggested that pneumonitis is a rare complication following vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).However, its clinical features and outcomes are not well known. The aim of this study was to identify the clinical characteristics and outcomes of patients with vaccine-associated pneumonitis following vaccination against SARS-CoV-2.
Methods:
In this nationwide multicenter survey study, questionnaires were distributed to pulmonary physicians in referral hospitals. They were asked to report cases of development or exacerbation of interstitial lung disease (ILD) associated with the coronavirus disease 2019 vaccine. Vaccine-associated pneumonitis was defined as new pulmonary infiltrates documented on chest computed tomography within 4 weeks of vaccination and exclusion of other possible etiologies.
Results:
From the survey, 49 cases of vaccine-associated pneumonitis were identified between February 27 and October 30, 2021. After multidisciplinary discussion, 46 cases were analyzed. The median age was 66 years and 28 (61%) were male. The median interval between vaccination and respiratory symptoms was 5 days. There were 20 (43%), 17 (37%), and nine (19%) patients with newly identified pneumonitis, exacerbation of pre-diagnosed ILD, and undetermined pre-existing ILD, respectively. The administered vaccines were BNT162b2 and ChAdOx1 nCov-19/AZD1222 each in 21 patients followed by mRNA-1273 in three, and Ad26.COV2.S in one patient. Except for five patients with mild disease, 41 (89%) patients were treated with corticosteroid. Significant improvement was observed in 26 (57%) patients including four patients who did not receive treatment. However, ILD aggravated in 9 (20%) patients despite treatment. Mortality was observed in eight (17%) patients.
Conclusion
These results suggest pneumonitis as a potentially significant safety concern for vaccines against SARS-CoV-2. Clinical awareness and patient education are necessary for early recognition and prompt management. Additional research is warranted to identify the epidemiology and characterize the pathophysiology of vaccine-associated pneumonitis.

Journal of the Korean Society of Emergency Medicine 2021;32(2):120-133
Objective:
The coronavirus disease 2019 (COVID-19) outbreak is currently ravaging the world and is a major threat to public health. Healthcare workers (HCWs) are at a high risk of acquiring and transmitting COVID-19. Hence, HCWs are also experiencing emotional and behavioral changes. The purpose of this study was to compare emotional changes and stress between occupations and to investigate the impact of emotions of HCWs during the COVID-19 outbreak.
Methods:
An anonymous, self-administered, previously validated questionnaire was given to HCWs at a hospital dedicated to infectious diseases in Korea during the COVID-19 outbreak. The participants were asked to evaluate stress factors, depressive moods, trauma, reasons for continuing to work, things that helped them work, coping strategies to reduce stress, motivators that could help them work during future outbreaks, and what they would like to do after the outbreak was over.
Results:
The total number of participants was 400. The average age of participants was 34.69±9.44. Stress and depressive moods showed variations in the job-to-job comparisons. Ethical duty and the professionalism of the HCWs pushed them to continue with their jobs. The news of a decline in the number of patients was helpful to HCWs. The implementation of personal hygiene programs helped in reducing stress. The provision of adequate personal protective equipment was a factor that would encourage them to work during any future outbreak. The participants wanted to go on a trip after the outbreak was over.
Conclusion
Our findings indicate that the COVID-19 outbreak had a significant emotional impact on HCWs. The concerns of HCWs may affect their work efficiency in an outbreak and should be addressed by incorporating appropriate management strategies while planning to combat an outbreak.

Journal of the Korean Society of Emergency Medicine 2021;32(6):509-524
Objective:
The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus-2, is a global concern. This study aimed to examine the clinical characteristics, demographics and outcomes of COVID-19 patients in the emergency department (ED) and explore clinical predictors of in-hospital mortality.
Methods:
This single-center, retrospective, observational study used 1,003 adult patients with laboratory-confirmed COVID-19 who went to the ED and were admitted to the hospital between February 28 and September 30, 2020.
Results:
The median age of the included patients was 55 (37-68) years, and 533 were women (53.1%). Severe COVID-19 was noted in 173 patients (17.2%); seven patients (0.7%) received mechanical ventilation. The mortality rate was 2.1%. Multivariable Cox regression analysis found the risk factors associated with in-hospital death of patients (age >70 years [hazard ratio (HR), 27.411; P<0.001], albumin level <3.5 g/dL [HR, 12.273; P<0.001], CURB-65 [confusion, urea nitrogen, respiratory rate, blood pressure, 65 years of age and older] score ≥3 [HR, 10.137; P=0.002] and platelet count <100×109/L [HR, 3.281; P=0.024]) on admission.
Conclusion
Age>70 years, hypoalbuminemia, CURB-65≥3 and thrombocytopenia on admission were independent risk factors for mortality in patients hospitalized with COVID-19. Early detection of these predictors and application of CURB-65 score in the ED may provide guidance for appropriate risk stratification at triage and disposition of patients at increased risk of poor prognosis.

Journal of the Korean Society of Emergency Medicine 2020;31(3):330-338
Objective:
This study described the effectiveness of the one-stop treat system (OTS) and the improvements characterizing the patients who come to an emergency medical center via the one-stop treat system for heavily drunken people
Methods:
An observational retrospective study was conducted on patients, aged 19 years or older, who visited the emergency department (ED) from January 2014 to December 2017 with alcohol intoxication (AI). The subjects were divided into two groups, that is, AI patients who come to ED directly or those who came via OTS. We compared and analyzed the characteristics of two groups including gender, age, date, mode of the ED visit, level of consciousness, diagnosis, ED length of stay (LOS), hospital LOS, and final outcomes.
Results:
A total of 8,144 patients were enrolled in the study. There were 2,221 AI patients who visited ED directly and 5,923 AI patients who visited ED via OTS. Patients arriving via OTS had more medical or surgical problems than the patients who came directly from the ED. Discharged patients via OTS showed a longer ED LOS (312 minutes [range, 169-520 minutes], P<0.001). Compared with patients who came directly from ED, the patients via OTS showed a higher admission rate (10.7% vs. 3.4%, respectively; P<0.001), and a higher death rate in ED (0.6% vs. 0%, respectively; P<0.001).
Conclusion
Compared the characteristics of the patients from ED directly in 2014-2017, the patients via OTS had higher severity and admission rate, and a longer ED LOS. Our findings suggest that we should pay attention to patients via OTS because the patients have high severity of illness.
