Objectives: The coronavirus disease 2019 (COVID-19) pandemic has led to a global shortage of medical resources; therefore, we investigated whether COVID-19 impacted the quality of non-COVID-19 hospital care in Korea by comparing hospital standardized mortality rates (HSMRs) before and during the pandemic. Methods: This retrospective cohort study analyzed Korean National Health Insurance discharge claim data obtained from January to June in 2017, 2018, 2019, and 2020. Patients' in-hospital deaths were classified according to the most responsible diagnosis categories. The HSMR is calculated as the ratio of expected deaths to actual deaths. The time trend in the overall HSMR was analyzed by region and hospital type. Results: The final analysis included 2 252 824 patients. In 2020, the HSMR increased nationwide (HSMR, 99.3; 95% confidence interval [CI], 97.7 to 101.0) in comparison to 2019 (HSMR, 97.3; 95% CI, 95.8 to 98.8). In the COVID-19 pandemic zone, the HSMR increased significantly in 2020 (HSMR, 112.7; 95% CI, 107.0 to 118.7) compared to 2019 (HSMR, 101.7; 95% CI, 96.9 to 106.6). The HSMR in all general hospitals increased significantly in 2020 (HSMR, 106.4; 95% CI, 104.3 to 108.5) compared to 2019 (HSMR, 100.3; 95% CI, 98.4 to 102.2). Hospitals participating in the COVID-19 response had a lower HSMR (HSMR, 95.6; 95% CI, 93.9 to 97.4) than hospitals not participating in the COVID-19 response (HSMR, 124.3; 95% CI, 119.3 to 129.4). Conclusions: This study suggests that the COVID-19 pandemic may have negatively impacted the quality of care in hospitals, especially general hospitals with relatively few beds. In light of the COVID-19 pandemic, it is necessary to prevent excessive workloads in hospitals and to properly employ and coordinate the workforce.

Background: Based on the increase in the needs for convalescent rehabilitation medical services in Korea, this study aims to calculate the needs for rehabilitation services and examine its determinants for 229 regions. Methods: Claim data from the Health Insurance Review and Assessment Service were used to estimate patients who need to receive rehabilitation services, and data from various sources were also used for analysis. The number of cases and incidence rates of hospitalization related to convalescent rehabilitation were calculated to estimate the needs for services by region, and the results were visualized via a map. Multivariate regression and fixed effects regression using panel data were performed to identify the determinants of regional variation of the incidence rate. Results: First, the incidence rate of rural areas such as Jeolla-do, Gyeongsang-do, and Chungcheong-do was higher than urban areas (metropolitan cities). Second, the population, proportion of the elder, medical aid recipients, financial independence, traffic deaths, smoking, diabetes rate, and medical infrastructure correlated significantly with the incidence rate. Third, 'rho' values which mean the fraction of variance due to individual terms in panel data regression models were 0.965 and 0.976, respectively. Conclusion: The incidence rate of hospitalizations was correlated with most independent variables in this study and there is a gap between urban and rural areas. These regional disparities are fixed in our society. An improved regional convalescent rehabilitation system is suggested to cover the entire area including rural areas with a high rate of aging.

Objectives : The purpose of this study is to analyze the proportion of admission via the emergency room(the rest is ER) in an emergency medical center and to examine the factors related to admission. Methods : This study used 2005 National Health Insurance claims data for admitted patients of 112 hospitals having emergency medical centers in Korea. The study sample had 2,335,610 patients. The data was classified into emergency admission and non-emergency admission. To investigate the factors affecting the type of admission, the following were included as independent variables: type of health assurance_(national health insurance beneficiaries or medical aid beneficiaries), demographic characteristics_ (sex, age), cause of admission_ (disease or injury), whether an operation was performed or not, DRG severity level, the number of beds, and the location of the hospital. Data were analyzed using the Chi-square test for the differences in emergency admission rates for each variables, and multiple logistic regression analysis was used for identifying the factors affecting admission type. Results : The proportion of admission via the ER accounted for 40.6% of the total admission among hospitals having emergency medical centers. The risk of admission via ER was relatively high for patients who were male, the aged, the injured, the surgical patients, the patients having more severe symptoms, and the patients admitted the hospitals located in metropolitan areas, and the patients admitted the hospitals having 300-699 beds. Medical aid patients were more likely admitted through the emergency room than health insurance patients after other variables ware adjusted. Conclusions and Discussion : We analyzed the proportion of admission via the ER for the total admission rate of hospitals having an emergency medical center in Korea. And we explored the factors related to admission via the ER. This proportion may be used as an indicator of the adequacy of medical utilization or low accessibility to hospitals of patients with low socioeconomic status.

Concerns about growing health insurance expenditures became a national Issue in 2001 when the National Health Insurance went into a deficit. Increases in spending for ambulatory care shared the largest portion of the problem. Methods and systems to control the spending should be developed and a system to measure case mix of providers is one of core components of the control system. The objectives of this article is to examine the feasibility of applying Korean Diagnosis Related Groups (KDRGs) to classify health insurance claims for ambulatory care and to identify problem areas of the classification. A database of 11,586,270 claims for ambulatory care delivered during January 2002 was obtained for the study, and the final number of claims analyzed was 8,319,494 after KDRG numbers were assigned to the data and records with an error KDRG were excluded from the study. The unit of analysis was a claim and resource use was measured by the sum of charges incurred during a month at a department of a hospital of at a clinic. Within group variance was assessed by th coefficient of variation (CV), and the classification accuracy was evaluated by the variance reduction achieved by the KDRG classification. The analyses were performed on both all and non-outlier data, and on a subset of the database to examine the validity of study results. Data were assigned to 787 KDRGs among 1,244 KDRGs defined in the classification system. For non-outlier data, 77.4％ of KDRGs had a CV of charges from tertiary care hospitals less than 100％ and 95.43％ of KDRGs for data from clinics. The variance reduction achieved by the KDRG classification was 40.80％ for non-outlier claims from tertiary care hospitals, 51.98％ for general hospitals, 40.89% for hospitals, and 54.99% for clinics. Similar results were obtained from the analyses performed on a subset of the study database. The study results indicated that KDRGs developed for a classification of inpatient care could be used for ambulatory care, although there were areas where the classification should be refined. Its power to predict tile resource utilization showed a potential for its application to measure case mix of providers for monitoring and managing delivery of ambulatory care. The issue concerning the quality of diagnostic information contained in insurance claims remains to be improved, and significance of future studies for other classification systems based on visits or episodes is guaranteed.

Objectives : The aim of this study is to assess the usage of diagnosis codes for somatic dysfunctions and the general characteristics of patients diagnosed with the code, by analyzing health insurance data provided by the Health Insurance Review & Assessment Service(HIRA) of Korea. This investigation is intended to outline future and willing to contribute to further use of diagnosis code and the approach of Oriental Medicine to somatic dysfunction. Materials and Methods : By analyzing HIRA data, those diagnosed with M99 codes, a code attributed to somatic dysfunction, were selected for analysis. Patients included were assessed for the relevant general characteristics, and the specific diagnostic criteria. The current usage rates and noteworthy characteristics of diagnostic codes of somatic dysfunctions were assessed. A comparative analysis between clinical departments and subcategories, and a comparative analysis to data of 2014 was conducted. Results : Patients given M99 codes constituted a small minority of all patients diagnosed in 2011 as shown by HIRA data. The codes were more frequently to older patients, females, outpatients, and those who filed for Health Insurance compensation. Medical institutions participating in the diagnosis were mostly primary care facilities, usually specializing in orthopedic(Western medicine sector) and internal medicine (Oriental Medicine sector). The most registered code in 2011 and 2014 was M995. The same trend can be observed in Oriental/Western medicine institutions and Public health center, on the other hand, between them, have some different patterns both 2nd and 3rd. Conclusions : This investigation is that of current usage of diagnostic codes of somatic dysfunction. HIRA insurance claim data was analyzed. Based on the current results, more precise diagnostic standards of somatic dysfunction are warranted. This study will provide a foundation for future Oriental Medicine approach to somatic dysfunctions.

경제의 세계화와 지식정보화 사회로의 진입과 함께 초래된 경영환경의 급속한 변화는 의료기관들에게도 경쟁력강화를 위한 변신을 강요하게 되었다. 다시 말하면, 의료기관들은 선진 의료기술의 확보, 환자들에 대한 서비스제고와 함께 경영의 효율성 증대라는 세가지 목표를 동시에 달성해야만 하는 상황에 놓이게 된 것이다. 본 연구는 의료기관들이 당면하고 있는 이러한 세가지 과제 중 병원의 경영효율성 증대를 위한 한가지 대안으로 진료비 청구삭감의 빈도 및 발생 가능성을 낮추기 위한 해법의 마련이 시도되었다. 진료비청구삭감이란 의료기관들이 환자들에 대한 의료서비스에 대한 진료비 중 의료보험으로 인해 환자들이 감면 받은 진료비를 건강보험심사원에 청구하면, 심사원이 의료기관의 청구내역의 적정여부를 심사하여 적정하지 않은 내용에 대한 청구금액을 삭감하는 제도를 이른다. 청구금액에 삭감이 발생하면 해당 의료기관의 수입이 감소하는 것은 물론 원인분석이나 재청구 작업등에 비용과 인력이 이중으로 투입되게 되어 의료기관의 경영에 부담을 주게 되고, 이러한 상황이 빈발하게 되면 해당 의료기관에 대한 환자와 건강보험심사평가원의 신뢰에 문제가 발생하게 된다. 그러므로, 효과적인 진료비 청구삭감분석시스템에 의한 사전대비의 필요성이 높아지게 되는 것이다. 이를 위하여 본 연구에서는 진료비 청구삭감분석을 위한 프로토타입의 개발이 시도되었다. 프로토타입은 데이터마이닝 기법 중 연관분석 알고리즘을 적용하여 개발되었으며, 이렇게 개발된 프로토타입을 D의료원에서 10개월간 발생한 실제 진료데이타를 사용하여 성능을 시험하였다.

One of the most important factors that affect a person's risk of injury in a motor vehicle crash is the age of the person. This study investigates the characteristics of crash injuries among young, middle-aged and older drivers and occupants. Based on the comprehensive claim data from automobile insurance from 2000 to 2007, this study examines in great detail the drivers and occupants injury body regions and severity by age in car-to-car frontal crashes. It has been shown that elderly drivers and occupants suffer more injuries at a chest region compared to the middle-aged group. This research calls attention to the need for design to make vehicles more protective for older drivers in car-to car frontal crashes.

The purpose of this study was to investigate the association of obesity with medical care use and costs according to overall diseases, cerebrovascular diseases (CVD), ischemic heart disease (IHD), hypertension (HTN) and diabetes mellitus (DM). The final sample was a group of persons who were free of diseases mentioned above and were not underweight. Their baseline screening program data and health insurance contribution data were connected with a 7-year medical claim database. The participants were classified according to their baseline BMI into normal, overweight, obese, and severely obese groups. Given the disease type, the total costs of DM showed the largest difference in each obesity group in both males and females. Also, the pharmacy costs for DM were more relevant than any other type of service to the obesity level. Considering the high prevalence of obesity and the relevantly increased medical care use and costs, there is a need for reduction in medical costs through obesity prevention efforts.

Since the inception of the National Tuberculosis Control Program in 1962, the incidence of tuberculosis and its associated mortality has declined dramatically due to effective anti-tuberculosis drugs and a systematic control program. The prevalence of radiographically active tuberculosis has fallen from 5.1% in 1965 to 1.0% in 1995. However, tuberculosis is still a major problem, as the mortality rate is still higher compared to other developed countries. Furthermore, tuberculosis is currently re-emerging in HIV/AIDS epidemic countries. In order to lower the tuberculosis death rate to the levels of developed countries, the tuberculosis control efforts in private healthcare institutions and the national tuberculosis control program in the public sector, need to work together more effectively and efficiently. In this paper, the quthor reviewed the current situation regarding tuberculosis management in private healthcare institutions of Korea based on the literature and the National Health Insurance Claim data, and the future tasks of tuberculosis management are suggested.
