Background: In workers with moderate to severe work-related traumatic brain injury (wrTBI), this study aimed to investigate the effect of the timing of rehabilitation therapy initiation on the length of hospital stay and the factors that can influence this timing. Methods: We used data obtained from the Republic of Korea's nationwide Workers' Compensation Insurance. In the Republic of Korea, between the years 2010 and 2019, a total of 26,324 workers filed a claim for compensation for moderate to severe wrTBI. Multiple regression modeling was performed to compare the length of hospital stay according to the timing of rehabilitation therapy initiation following wrTBI. According to the timing of the initiation of rehabilitation therapy following TBI, the proportions of healthcare institutions that provided medical care during each admission step were compared. Results: The length of hospital stay for workers who started rehabilitation therapy within 90 days was significantly shorter than that for workers who started rehabilitationment were first admitted to tertiary hospitals. Approximately 39% of patients who received delayed rehabilitation treatment were first admitted to general hospitals, and 28.5% were first admitted to primary hospitals. Conclusions: Our findings demonstrate the importance of early rehabilitation initiation and that the type of healthcare institution that the patient is first admitted to after wrTBI may influence the timing of rehabilitation initiation. The results of this study also emphasize the need to establish a Worker's Compensation Insuranceespecialized rehabilitation healthcare delivery system.

In this study, a practical model for health information management education using the EMR education system at universities for nurturing health care information managers was studied. Currently, there is no practical training course for health care information management in the standards for evaluation and certification of health care information management education introduced to strengthen the job competency of health care information managers. Accordingly, the program was constructed so that the practice program suggested as an educational environment in the Health and Medical Information Management Education Evaluation and Certification Manual can be practiced in the EMR education system. In addition, a practical model that can be performed according to the on-site practice guidelines for health and medical information management for each program was studied. Using the health care information management education EMR system, master data management, patient registration, doctor prescription, medical cost calculation, health insurance claim management, form management, discharge registration, cancer registration, unrecorded management, health care data management, health care statistics, A practice model was studied so that practice on information protection/security management can be performed. It will be possible to play a role as a health care information management expert by raising the quality level of health care information management education through systematic and standardized health care information management practice courses at universities. Accordingly, it is necessary to cultivate health care information management experts who develop and manage medical services based on medical data analysis through practical training of health care information managers.

A new cost management system, called Activity Based Costing (ABC) system, has arisen to solve the limitation of a Traditional Cost Accounting (TCA) system until last two decades and ABC has been applied by many companies. TCA systems have limitation in tracing cost because they arbitrarily allocate overhead cost to the cost objects without standard for direct cost distribution. ABC is an accounting system that assigns costs to products or services based on the resources they consume. The costs of all activities are traced to the products for which they are performed. Therefore ABC is a cost management system that provides a matrix to accurately quantify consumed resources triggered by activities and activities triggered by products and services. There is little implementation of ABC in the health services field, one of service industries, due to complicated and many activities, and volatile cost object. However, the necessity for applying reasonable cost accounting system is largely issuing as strategy responding hostile environment, and financial pressure, and it is imperative to implement the Activity Based Costing (ABC) system. Therefore, this study presents the framework to develop ABC system for total health service organizations. Cost objects in this study base on medical service activities per health insurance claim from one general hospital located in Metropolitan Statistical Areas (MSAs). Medical service activities include all health insurance claims in the hospital. The purpose of the study is presenting useful tools and basic frame to develop Activity Based Costing system for health service organizations which want to use ABC system. The steps to develop ABC system for health service organizations are following: 1. Identifying of activity centers; 2. Definition of cost objects and activity by activity center; 3. Analysis of activity and tracing activity contribution; 4. Allocation of direct cost for specific activity; 5. Allocation of indirect cost for specific activity; 6. Allocation of depreciation for facilities, applicants, and consumption goods; 7. Allocation of administration cost; 8. Allocation of cost among activity centers; and 9. Tracing cost of cost objects by activity center. This study identified necessary information from existing reports which hospitals generally made by each step, and defined outcome which had to be produced in each step using this information. The steps of this study had limitation to apply all different size hospitals because the steps were structured ABC system by one hospital, however, this study used similar basic framework and methods with general cases. When a health service organization want to apply Activity Based Costing (ABC) system on all activities of it in future days, this study is very useful to design system structure in the health service organization.

This study was conducted to improve the quality of National Health Policy by analysing the effects of sociodemographic characteristics, Medical institutions characteristics and characteristics of Admission-Discharge on the length of stay in hospital for schizophrenic patients from the data of Health Insurance Review & Assessment Service. The subjects were 4,692 patients who were diagnosed with schizophrenia as main diagnosis from the data records of HIRA-NIS 2016. Regression analysis was performed to evaluate the effect on the length of stay. Sociodemographic characteristics, hospital characteristics and characteristics of Admission-Discharge were used as explanatory variables and length of stay in hospital was used as a dependent variable. The result of study showed that female, age, medical aid, the kind of hospital, gangweon-do and with mental disease were found to be the factors that affect the length of stay. The significance of this study is to use the public data for evaluating factors that affect the length of stay in hospital for schizophrenic patients. But this study did not consider disease severity, so further study is needed for evaluation of the effects of factors on the length of stay according to disease severity.

Objectives: This study was conducted to compare the medical care patterns of hypertensive patients between rural and urban areas. Methods: We selected one rural county(Region A where there were 19 public health centers; one health center, 8 health sub-centers and 10 community health posts) and two urban districts(Region B and C where there was no health sub-center and community health post) in Daegu city. Region B had similar socioeconomic characteristics with rural county A while region C had different characteristics. The medical insurance records of 14,422 incident patients (2,501 in region A, 4,873 in region B and 7,048 in region C) with diagnostic code of hypertension from September 1998 to August 1999 were reviewed. Incident patient was defined as a patient who had no record of medical fee claim for hypertension to the national health insurance corporation in past 6 months and visited a medical facility for hypertension for the first time. The data for annual visit days, annual prescription days and annual total medical expenses were abstracted. The medical care pattern was categorized by the number of annual visit days and prescription days. The most proper care group was defined as the patient who visited 6-15 days with 240 prescription days or more in a year. Results: The type of medical facilities for the most visit was clinics, 373.% and it was followed by general hospitals, 28.2%; public health centers, 24.7%; and hospitals, 9.8% in region A(p<0.05). In region B, it was clinics, 63.1% and followed by general hospitals, 27.6%; health center, 5.2%; and hospitals, 4.1%(p<0.05). In region C, it was clinics, 53.8% and followed by general hospitals, 35.0%; health center, 6.3%; and hospitals, 4.9%(p<0.05). Annual mean total medical expenses per patient was highest in region C(won195,993) and followed by region A(won191,683) and region B(won178,713). The proportion of the most proper care group was 7.7% in region A, 5.2% in region B and 6.7% in region C(p<0.05). According to the type of medical facilities for the first visit, the proportion of the most proper care group was highest(14.7%) in the patients of public health centers, and it was followed by general hospitals, 8.8%; clinics, 3.6%; and hospitals, 2.0% in region A(p<0.05). In region B, it was highest in general hospitals, 9.7% and followed by hospitals, 4.0%; health center, 3.6%; and clinics, 3.4%(p<0.05). In region C, it was highest in general hospitals, 10.1% and followed by clinics, 5.2%; hospitals, 4.1%; and health center, 3.1%(p<0.05). Conclusions: The proportion of proper care for hypertension was higher in rural area and it was attributed to the care of health center, sub-centers and community health posts which appeared to follow patients better than hospitals and clinics.

This study is to examine health care utilization and morbidity of disabled and non-disabled children in Korea to evaluate the health disparities. We used medical claim data of 2010 from the National Health Insurance Service-National Sample Cohort data. As a result of the analysis, the disabled children are not in good health condition because they have more frequency of medical service use, hospitalization rate, and more number of diseases and spent more on medical expenses than non-disabled children. Patterns of the most frequent disease differ from significantly between disable and non-disabled. Disabled children had a higher prevalence of selected birth defects and selected health conditions associated with physical disability and a lower prevalence of selected infection disease than children without disability. In conclusion, Health policy changes that would extend the access to health service for children with disabilities characterized by frequent medical care, hospitalization, excessive medical expenditure and complex diseases.

Background: Few studies have investigated unspecified or idiopathic pain associated with COIVD-19. This study aimed to provide the incidence rates of unspecified pain and idiopathic pain in patients with COVID-19 for 90 days after COVID-19 diagnosis. Methods: A propensity score matched cohort was used, including all patients with COVID-19 in South Korea, and analyzed their electronic medical records. The control group consisted of those who had not had tests for COVID-19 at all. Unspecified pain diagnoses consisted of diagnoses related to pain included in the ICD-10 Chapter XVIII. Idiopathic pain disorders included fibromyalgia, temporomandibular joint disorders, headaches, chronic prostatitis, complex regional pain syndrome, atypical facial pain, irritable bowel syndrome, and interstitial cystitis. Results: After matching, the number of participants in each group was 7,911. For most unspecified pain, the incidences were higher in the COVID-19 group (11.7%; 95% confidence interval [CI], 11.0-12.5) than in the control group (6.5%; 95% CI, 6.0-7.1). For idiopathic pain, only the headaches had a significantly higher incidence in the COVID-19 group (6.6%; 95% CI, 6.1-7.2) than in the control group (3.7%; 95% CI, 3.3-4.1). However, using a different control group that included only patients who visited a hospital at least once for any reasons, the incidences of most unspecified and idiopathic pain were higher in the control group than in the COVID-19 group. Conclusions: Patients with COVID-19 might be at a higher risk of experiencing unspecified pain in the acute phase or after recovery compared with individuals who had not had tests for COVID-19.

Background: Fixed-dose combinations have the advantage of improving patient compliance, but may increase the risk of duplicate prescriptions. As the use of fixed-dose combination antihypertensives increases, it is necessary to investigate the current status of class duplication prescriptions (CDP) in patients taking fixed-dose combination antihypertensives in Korea and to identify factors associated with CDP. Methods: We conducted a retrospective observational study using nationally representative claim data. Hypertensive patients aged 20 years or older taking fixed-dose combination antihypertensives were extracted. Among these patients, patients with CDP were identified. A chi-square test was applied to determine the differences between patients with CDP and non-CDP. The associated factors of CDP were identified through multiple logistic regression. Results: Of the 74,165 patients who were prescribed fixed-dose combination antihypertensives, 426 patients (0.6%) with CDP were identified. The most common antihypertensive class associated with CDP was calcium channel blockers (194 patients, 45.5%), followed by angiotensin II receptor blockers (136 patients, 31.9%). Patients aged 75 years or older (odds ratio [OR] 1.83, 95% confidence interval [CI] 1.02-3.52), chronic kidney disease (OR 4.45, 95% CI 2.15-8.25), chronic heart failure (OR 2.71, 95% CI 1.93-3.72), coronary artery disease (OR 2.22, 95% CI 1.60-3.03) and Medical Aid/Patriots and Veterans Insurance (OR 1.49, 95% CI 1.04-2.07) were significantly associated with increased CDP. Conclusions: The factors associated with CDP were the elderly, comorbidities, and low socioeconomic status. Since CDP can result in negative clinical outcomes, active intervention by the pharmacist is warranted.

Background: There has been lack of epidemiology of proximal humerus fracture using nationwide database in Asia. The purpose of this study was to investigate the incidence of proximal humerus fracture and its mortality following proximal humerus fracture in Korean over 50 years of age. Methods: The Korean National Health Insurance data were evaluated to determine the incidence and mortality of proximal humerus fracture aged 50 years or older from 2008 through 2012. Results: Proximal humerus fracture increased by 40.5% over 5 year of study. The incidence of fracture increased from 104.7/100,000 in 2008 to 124.7/100,000 in 2012 in women and from 45.3/100,000 in 2008 to 52.0/100,000 in 2012 in men, respectively. One year mortality rate after proximal humerus fracture was 8.0% in 2008 and 7.0% in 2012. One year mortality rate were 10.8% for men and 7.0% for women in 2008 and 8.5% for men and 6.4% for women in 2012. Conclusions: Our study showed that the proximal humerus fracture in elderly was recently increasing and associated with high mortality in Korea. Considering proximal humerus fracture was associated with an increased risk of associated fractures and an increased mortality risk, public health strategy to prevent the proximal humerus fracture in elderly will be mandatory.

Along with the development of scientific technologies, health care has been growing remarkably, and as the social life quality improves with increasing interest in health, the demand for medical service is rapidly increasing. However, medical accident and medical dispute also are rapidly increasing due to various factors such as, increasing sense of people's right, lack of understanding in the nature of medical practice, over expectation on medical technique, commercialize medical supply system, moral degeneracy and unawareness of medical jurisprudence by doctors, widespread trend of mutual distrust, and lack of systematized device for solution of medical dispute. This study analysed 30 cases of civil suit in the year between 1994 to 2004, which were selected among the medical dispute cases in dental field with the judgement collected from organizations related to dentistry and department of oral medicine, Yonsei university dental hospital. The following results were drawn from the analyses: 1. The distribution of year showed rapid increase of medical dispute after the year 2000. 2. In the types of medical dispute, suit associated with tooth extraction took 36.7% of all. 3. As for the cause of medical dispute, uncomfortable feeling and dissatisfaction with the treatment showed 36.7%, death and permanent damage showed 16.7% each. 4. Winning the suit, compulsory mediation and recommendation for settlement took 60.0% of judgement result for the plaintiff. 5. For the type of medical organization in relation to medical dispute, 60.0% was found to be the private dental clinics, and 30.0% was university dental hospitals. 6. For the level of trial, dispute that progressed above 2 or 3 trials was of 30.0%. 7. For the amount of claim for damage, the claim amounting between 50 million to 100 million won was of 36.7%, and that of more than 100 million won was 13.3%, and in case of the judgement amount, the amount ranging from 10 million to 30 million won was of 40.0%, and that of more than 100 million won was of 6.7%. 8. For the number of dentist involved in the suit, 26.7% was of 2 or more dentists. 9. For the amount of time spent until the judgement, 46.7% took 11 to 20 months, and 36.7% took 21 to 30 months. 10. For medical malpractice, 46.7% was judged to be guilty, and 70% of the cases had undergone medical judgement or verification of the case by specialists during the process of the suit. 11. In the lost cases of doctors(18 cases), 72.2% was due to violence of carefulness in practice and 16.7% was due to missing of explanation to patient. Medical disputes occurring in the field of dentistry are usually of relatively less risky cases. Hence, the importance of explanation to patient is emphasized, and since the levels of patient satisfaction are subjective, improvement of the relationship between the patient and the dentist and recovery of autonomy within the group dentist are essential in addition to the reduction of technical malpractice. Moreover, management measure against the medical dispute should be set up through complement of the current doctors and hospitals medical malpractice insurance which is being conducted irrationally, and establishment of system in which education as well as consultation for medical disputes lead by the group of dental clinicians and academic scholars are accessible.
