${\beta}$-blockers are considered as standard therapy for patients with stable chronic heart failure (CHF) and to prolong survival and reduce hospitalizations. We examined the effects of the ${\beta}$-blocker on mortality, hospitalization and symptoms in patients with CHF and the related factors to the use of ${\beta}$-blockers. Patients in New York Heart Association class II-IV were included if they were treated for heart failure from January 2002 to June 2002. At baseline, 6 months, and 12 months, they were assessed for the change of NYHA class and all deaths and hospital admissions. (omitted)

Objective : To investigate the effects of trauma center establishment on the clinical characteristics and outcomes of trauma patients with traumatic brain injury (TBI). Methods : We enrolled 322 patients with severe trauma and TBI from January 2015 to December 2016. Clinical factors, indexes, and outcomes were compared before and after trauma center establishment (September 2015). The outcome was the Glasgow outcome scale classification at 3 months post-trauma. Results : Of the 322 patients, 120 (37.3%) and 202 (62.7%) were admitted before and after trauma center establishment, respectively. The two groups were significantly different in age (p=0.038), the trauma location within the city (p=0.010), the proportion of intensive care unit (ICU) admissions (p=0.001), and the emergency room stay time (p<0.001). Mortality occurred in 37 patients (11.5%). Although the preventable death rate decreased from before to after center establishment (23.1% vs. 12.5%), the difference was not significant. None of the clinical factors, indexes, or outcomes were different from before to after center establishment for patients with severe TBI (Glasgow coma scale score ${\leq}8$). However, the proportion of inter-hospital transfers increased and the time to emergency room arrival was longer in both the entire cohort and patients with severe TBI after versus before trauma center establishment. Conclusion : We confirmed that for patients with severe trauma and TBI, establishing a trauma center increased the proportion of ICU admissions and decreased the emergency room stay time and preventable death rate. However, management strategies for handling the high proportion of inter-hospital transfers and long times to emergency room arrival will be necessary.

Objectives: Parental socioeconomic status (SES) exerts a substantial influence on children's health. The purpose of this study was to examine factors determining children's private health insurance (PHI) enrolment and children's healthcare utilization according to PHI coverage. Methods: Korea Health Panel data from 2011 (n=3085) was used to explore the factors determining PHI enrolment in children younger than 15 years of age. A logit model contained health status and SES variables for both children and parents. A fixed effects model identified factors influencing healthcare utilization in children aged 10 years or younger, using 2008 to 2011 panel data (n=9084). Results: The factors determining children's PHI enrolment included children's age and sex and parents' educational status, employment status, and household income quintile. PHI exerted a significant effect on outpatient cost, inpatient cost, and number of admissions. Number of outpatient visits and total length of stay were not affected by PHI status. The interaction between PHI and age group increased outpatient cost significantly. Conclusions: Children's PHI enrolment was influenced by parents' SES, while healthcare utilization was affected by health and disability status. Therefore, the results of this study suggest disparities in healthcare utilization according to PHI enrollment.

Objective : We aimed to examine trends in critically ill neurology-neurosurgery (NNS) patients who were admitted to the intensive care unit (ICU) in South Korea and identify risk factors for in-hospital mortality after ICU admission in NNS patients. Methods : This nationwide population-based retrospective cohort study enrolled adult NNS adult patients admitted to the ICU from 2010 to 2019 extracted from the National Health Insurance Service in South Korea. The critically ill NNS patients were defined as those whose main admission departments were neurology or neurosurgery at ICU admission. The number of ICU admission, age, and total cost for hospitalization from 2010 to 2019 in critically ill NNS patients were examined as trend information. Moreover, multivariable logistic regression modeling was used to identify risk factors for in-hospital mortality among critically ill NNS patients. Results : We included 845474 ICU admission cases for 679376 critically ill NNS patients in South Korea between January 1, 2010 to December 31, 2019. The total number of ICU admissions among NNS patients was 79522 in 2010, which increased to 91502 in 2019. The mean age rose from 62.8 years (standard deviation [SD], 15.6) in 2010 to 66.6 years (SD, 15.2) in 2019, and the average total cost for hospitalization per each patient consistently increased from 6206.1 USD (SD, 5218.5) in 2010 to 10745.4 USD (SD, 10917.4) in 2019. In-hospital mortality occurred in 75455 patients (8.9%). Risk factors strongly associated with increased in-hospital mortality were the usage of mechanical ventilator (adjusted odds ratio [aOR], 19.83; 95% confidence interval [CI], 19.42-20.26; p<0.001), extracorporeal membrane oxygenation (aOR, 3.49; 95% CI, 2.42-5.02; p<0.001), and continuous renal replacement therapy (aOR, 6.47; 95% CI, 6.02-6.96; p<0.001). In addition, direct admission to ICU from the emergency room (aOR, 1.38; 95% CI, 1.36-1.41; p<0.001) and brain cancer as the main diagnosis (aOR, 1.30; 95% CI, 1.22-1.39; p<0.001) are also potential risk factors for increased in-hospital mortality. Conclusion : In South Korea, the number of ICU admissions increased among critically ill NNS patients from 2010 to 2019. The average age and total costs for hospitalization also increased. Some potential risk factors are found to increase in-hospital mortality among critically ill NNS patients.

이 연구는 3차 진료기관 응급실의 기능을 정상화하기 위한 기초 자료를 수집하기 위하여, 한 3차 진료기관 응급실을 방문한 환자를 대상으로, 입원 결정서 발부와 환자의 입원 결정 양상 및 이에 영향을 미치는 요인을 파악하였다. 또한 적절성 평가 지침을 이용하여 응급실을 통한 입원의 적절성을 평가하였고 입원의 적절성과 응급실 입원 대기시간의 적절성에 영향을 미치는 요인을 분석하였다. 입원 결정서 발부에 영향을 미치는 요인은 환자의 내 외과계 구분, 진료과수, 환자 상태, 방문 경로, 방문 시간과 방문 요일이었다. 입원 결정서 발부 후 환자의 입원 여부는 환자의 성, 환자 상태, 방문 경로, 방문 요일에 따라 달리 나타났다. 환자의 연령, 내 외과계 구분과 방문 요일에 따라 입원의 적절성에 차이를 보였다. 입원 대기시간은 환자의 연령이 증가할수록 적절성이 낮았다. 이 연구를 통하여 응급실을 통한 입원 중 반수 이상의 입원이 부적절한 입원으로 평가되었고, 이 중 일부는 입원을 빨리 하기 위한 방법의 하나로 응급실을 편법으로 이용하고 있기 때문인 것으로 판단되었다. 또한 입원 결정서가 발부된 환자 중 상당수의 환자가 병상을 구할 수 없어 입원하지 못하고 있는 것으로 보아, 3차 진료기관의 환자 집중 현상과 응급실 과밀화 요인 해소를 위한 의료정책의 수립이 필요함을 확인할 수 있었다.

Purpose: There has been no nationwide surveillance survey of poisoning cases in Korea. This study examined the clinical characteristics of poisoning admissions in order to obtain preliminary data for future planning. Methods: This study retrospectively reviewed the data on poisoning admissions of 150 hospitals based on the hospital discharge injury surveillance data of Center for Disease Control and Prevention in Korea from January to December in 2004. The demographic data, poisons used, causes of poisoning, reasons for attempted suicide and mortality rate was investigated according to the age group. The factors associated with mortality were also evaluated. Results: A total 836 patients admitted for poisoning were analyzed. Their mean age was $46.5{\pm}19.5$ years (male 415, female 421). The most frequent age group was the 4th and 5th decades. The most common poisons involved were pesticides (45%) and medications (23%). The majority (64%) involved intentional poisoning except for those in the 1st decade. The most common reason for the attempted suicide was family problems. However, individual disease was the most common reason in those over 60 years. The overall mortality rate was 8.7% (73/836). Pesticides and being elderly (over 65 years old) were strongly correlated with fatality. Conclusion: The incidence of intentional poisoning increases from the 2nd decade making it a preventable injury. "Overall, the incidence of intentional poisoning increases from the 2nd decade". Therefore, there is a need to frame a prevention policy corresponding to each factor related to fatality, such as an elderly population and pesticides.

A small number of high cost patients usually spend a larger proportion of scarce health resources. Korea is no exception. Under the national health insurance, 12% of the insured persons have consumed approximately half of the national health insurance expenditures. Therefore, it is necessary to identify the characteristics of the high cost patient group, if we would like to reduce them. This study has defined high cost patients as those who have spent one and half million won and over per 6 months. The study reveals that high cost users are those who have a longer length of stays(LOS), 40days of LOS in the 6 months, have multiple admissions, 2 to 3 admissions per 6 months and are the elderly patients. They have spent 814.126won per on the average, and commonly suffered from malignant neoplasms, circulatory diseases, fracture, diabetes mellitus, etc. Unlike the case of western developed countries, early readmissions are not the major causes of high cost spending in Korea. Undoubtedly, a lengthy admission is the main cause of large spending. Health policies should vigorously be explored to respond appropriately. There are evidences that hospital beds are often misused. As the Korean health care system is lacking in a mechanism of patient evaluation under the fee-for-service remuneration system, an idea of progressive patient care needs to be tested. The Goverment should set up health policy to diversify the role of long-term care facilities and encourage people to establish them. Further studies are needed to identify factors influencing large medical bills necessary for formulating the health policy on cost containment.
