PURPOSE: This study was carried out to investigate survival rate and the factors affecting survival among lung cancer patients who have been registered in Daejeon Cancer Registry from 1998 to 2000. METHODS: Kaplan-Meier method and Cox proportional hazard model were used to evaluate the factors affecting survival of lung cancer patients. RESULTS: Lung cancer was more common in men than women, with an overall sex ratio in Daejeon, Korea of roughly 3:1. The incidence of lung cancer was 17.1 per 100,000 population in 1998, 21.4 in 1999, and 22.4 in 2000. Average age of incidence was 64.8 years old and 11.7% of study subjects having family history of lung cancer. Forty eight % of lung cancer was diagnosed as Stage III and 40.6% as Stage IV. Histologically, squamous cell carcinoma was 39.7% of all and most frequent, and then adenocarcinoma 25.5%, and small cell carcinoma 19.3%. 3-year survival rate of female was higher than that of males, and that of smoker was the lowest among groups according to the smoking level. Survival rate by age fell dramatically in group over 70 years. Lung cancer patients diagnosed as Stage III and Stage IV had a much lower survival rate than those diagnosed as Stage I or II. Stage, LDH and age were proved to be important variables that affect the mortality of lung cancer patients. CONCLUSION: We found that the stage at diagnosis was a critical factor that affected the survival of lung cancer patients from this study. So It is essential to develop early diagnosis of lung cancer and then it needs to evaluate the effectiveness of that.

OBJECTIVES:
The purpose of this study was to estimate the incidence of injuries and to identify their causes by classifying injuries according to various categories including age, sex, mechanism of injury, body parts injured, and place of injury.
METHODS:
This study used data from the Korea National Hospital Discharge In-depth Injury Survey (KNHDIS) from 2004 to 2016. The KNHDIS is conducted annually by the Korea Centers for Disease Control and Prevention, and its survey population includes all hospitalized patients discharged from medical institutions that have 100 or more beds, such as hospitals, general hospitals, and secondary community health centers. The number of injured cases is weighted and estimated using the mid-year estimated population of each year.
RESULTS:
The injury discharge rate steadily increased since 2004 (1,505 per 100,000 population in 2004, 2,007 per 100,000 population in 2016) and most injuries were unintentional (annual average of 94.7%). On average, during the 13-year study period, the injury rate for males was 1.5 times as high as for females. The 2 main causes of injury were consistently traffic accidents and falls. Notably, the rate of injuries resulting from falls rose by 1.7-fold from 463 to 792 per 100,000 people, and exceeded the rate of traffic accidents in 2016.
CONCLUSIONS
The incidence of injuries steadily increased after the survey was first conducted, whereas mortality resulting from injuries mostly remained unchanged. This suggests that effective strategies and interventions should be reinforced to reduce unintentional injuries.

Objectives:
People-centered care and social protection are critical for improving tuberculosis (TB) treatment outcomes. This study aimed to evaluate whether a vulnerability assessment tool, developed for an enhanced community-based care and management (ECCM) program in 2 Korean cities, could predict and improve final TB treatment outcomes based on patients’ vulnerability levels.
Methods:
Treatment outcomes in the ECCM group were compared with those in a control group, stratified by vulnerability level. During stage 1, one city served as the intervention region and the other as the control, with a crossover in stage 2. The vulnerability assessment included all notified patients with TB, and those identified as highly vulnerable in the intervention group received social support following a consultation with a case manager.
Results:
The vulnerability assessment tool demonstrated moderate predictive ability for unfavorable outcomes, with an area under the curve of 0.70 (95% confidence interval, 0.63 to 0.77). The patients with high vulnerability who received ECCM treatment demonstrated a 19.8-percentage point (%p) higher treatment success rate than the high vulnerability subcategory of the control group. ECCM also appeared to reduce loss to follow-up and TB-related mortality by 8.4%p and 7.3%p, respectively, although these findings should be interpreted with caution.
Conclusions
The results suggest that providing social support tailored to patient vulnerability at the time of diagnosis could improve TB treatment outcomes.

Background:
The Field Epidemiology Training Program Frontline, initiated by the Korea Disease Control and Prevention Agency in 2019, aims to enhance the competencies of infectious disease practitioners across 17 regions in South Korea. With the September 2024 amendment to the Infectious Disease Prevention Act mandating infectious disease prevention and crisis response training for government employees who are associated with infectious diseases responses, there is an urgent need to assess and optimize the effectiveness and cost-efficiency of such competency-based education programs amidst constraints of budget and manpower.
Methods:
This study examined the educational needs and priorities of public health competencies among infectious disease practitioners. The competency framework for Infectious Disease Response Practitioners (IDRP) in South Korea was used to evaluate the validity, importance, and performance level of competencies for infectious disease response personnel. For the training needs analysis, differences in performance by group were analyzed, and an importance performance analysis (IPA) was conducted using the Borich Needs Assessment based on the IPA matrix to derive training priorities.
Results:
The analysis revealed a significant gap between perceived importance and selfreported performance levels in most competencies, especially epidemiologic methods.Competencies related to safety and ethics, fieldwork, and crisis management have high importance and performance ratings, indicating a need for ongoing training. Of the 27 competencies, the IPA identified specific training needs and priorities, suggesting eight competencies for focused intervention to strengthen the capacity of IDRPs.
Conclusion
The IDRP competency framework in South Korea plays a pivotal role in establishing a standardized, competency-based approach to training IDRP. The identified gaps and training priorities highlight the need for continued curriculum development and the integration of real-world, field-based scenarios into training programs.

Purpose:
This study compared COVID-19 vaccination intentions in those with and without chronic diseases (CDs and non-CDs) in South Korea. We hypothesized that the factors associated with COVID-19 vaccination intentions would differ between CDs and non-CDs in South Korea.
Methods:
Using survey data collected through a Korean online panel in June 2021, we conducted a crosssectional secondary data analysis. Of the 2292 participants, 411 had at least one chronic disease. To construct a comparable dataset, we selected non-CDs via a 1:1 case-control matching for age and gender.We then utilized a multivariable binary logistic regression model to explore the factors contributing to COVID-19 vaccination intentions in CDs and non-CDs.
Results:
All told, over 75% of participants in both groups indicated that they intended to vaccinate against COVID-19. In both groups, those who mistrusted general vaccine benefits reported significantly lower COVID-19 vaccination intentions. Regarding factors associated with vaccination intentions, CDs identified anxiety regarding coronavirus and exposure to COVID-19 vaccination promotions at the community level, while non-CDs highlighted hesitancy regarding vaccines and confidence in government/health services.
Conclusion
Improving vaccination acceptance will require the development and implementation of tailored approaches for CDs and non-CDs and efforts to minimize general vaccine mistrust.
