In this study, we analyzed the use of general radiography imaging and effective dose in inpatients. Our aim is to help reduce national medical radiation exposure doses and develop rational health-care financial policies. The effective dose for each general radiography was calculated using the ALARA-GR program for 53 types (total: 260 codes) general radiography codes selected from 'National Health Insurance Care Benefit Cost'. The usage of general radiography was analyzed in the 2018 inpatient patient data of the Health Insurance Review and Assessment Service, and the effective dose for each general radiography was analyzed. 89.00% of inpatients undergo general radiography imaging at least once, with an average of 12.63 scans per person and an effective dose of 1.00 mSv. Those who received support from Medical Aid showed a higher value compared to those who were insured by National Health Insurance, with 17.39 cases and 1.43 mSv (p<.001). Chest had the highest usage rate at 23.12% for general radiography imaging, while L-spine had the highest effective dose at 24.53%. It is estimated that 420 inpatients patients undergo 121 to 820 general radiography imaging procedures per year, and 233 inpatients are estimated to have an annual effective dose of >20.00~58.25 mSv. Rational use of health-care finances and the practice of medical radiation safety management are essential for the well-being of individuals, the enhancement of quality of life, and the improvement of health-care quality.

COVID-19 is a viral pandemic disease that spreads widely all around the world. The only way to identify COVID-19 patients at an early stage is to stop the spread of the virus. Different approaches are used to diagnose, such as RT-PCR, Chest X-rays, and CT images. However, these are time-consuming and require a specialized lab. Therefore, there is a need to develop a time-efficient diagnosis method to detect COVID-19 patients. The proposed machine learning (ML) approach predicts the presence of coronavirus based on clinical symptoms. The clinical dataset is collected from the Israeli Ministry of Health. We used different ML classifiers (i.e., XGB, DT, RF, and NB) to diagnose COVID-19. Later, classifiers are optimized with the Bayesian hyperparameter optimization approach to improve the performance. The optimized RF outperformed the others and achieved an accuracy of 97.62% on the testing data that help the early diagnosis of COVID-19 patients.

Purpose: We examined the prevalence of anemia, annual screening for anemia, and treatment of anemia with iron among children with inflammatory bowel disease (IBD). Methods: A retrospective study of U.S. pediatric patients with IBD was performed in the MarketScan commercial claims database from 2010-2014. Children (ages 1-21) with at least two inpatient or outpatient encounters for IBD who had available lab and pharmacy data were included in the cohort. Anemia was defined using World Health Organization criteria. We used logistic regression to determine differences in screening, incident anemia, and treatment based on age at first IBD encounter and sex. Results: The cohort (n=2,446) included 1,560 Crohn's disease (CD) and 886 ulcerative colitis (UC). Approximately, 85% of CD and 81% of UC were screened for anemia. Among those screened, 51% with CD and 43% with UC had anemia. Only 24% of anemia patients with CD and 20% with UC were tested for iron deficiency; 85% were iron deficient. Intravenous (IV) iron was used to treat 4% of CD and 4% UC patients overall and 8% of those with anemia. Conclusion: At least 80% of children with IBD were screened for anemia, although most did not receive follow-up tests for iron deficiency. The 43%-50% prevalence of anemia was consistent with prior studies. Under-treatment with IV iron points to a potential target for quality improvement.

Purpose: This study was to investigate relationships among self-care, self-efficacy and social support in patients with chronic obstructive pulmonary disease (COPD). Method: The subjects were 114 patients with COPD from both inpatient and outpatient department sin a branch hospital of C university located in Gyeonggi-do from April 2005 to May 2005. Self-care was measured by No Hyeon-Suk's (2003) scale, self-efficacy was measured by Wigal et al's (1991) scale, social support was measured by Park Sun-Ju's (2001) scale. Data were analyzed by using t-test, ANOVA, Pearson correlation coefficient, and stepwise multiple regression. Results: The total mean was 3.1 for self-care, 3.5 for self-efficacy, and 4.3 for social support. The levels of self-efficacy and social support were significantly and positively correlated with the level of self-care. The level of self-care was influenced by social support explaining 16% and the level of self-efficacy explaining 6%, giving a total of 22%. Conclusion: The result of this study showed that the patients with COPD carried out self-care better when they had higher levels of self-efficacy and social support. Thus, we will improve the level of self-care of patients with COPD by nursing intervention to increase self-efficacy and social support.

Purpose: The objective of this study was to analyze diabetic foot patients' direct service costs until the cure of the disease. Materials Methods: The subjects of this study were randomly sampled 60 patients who had been treated for diabetic foot at one of two tertiary hospitals and cured of the disease during from January 2008 to December 2009, and whose diagnostic code was E11.5 or E14.5. Data were collected from medical records and direct service costs were analyzed using data on the payments of individual service charges. Direct service costs spent at other medical institutions for the same disease were excluded. Collected data were analyzed using descriptive statistics. Results: The subjects' mean hospital stay was 29 days, and mean period until cure was 132 days. The inpatient cost per patient was 10,844,648 won, outpatient cost was 715,751 won, and home care services cost was 641,854 won, so total direct service cost per patient was 11,913,419 won. The total direct service cost in patients who had their foot amputated was 12,769,822 won, 1.3 times higher than without amputation, who had vascular intervention was 16,219,477 won, 1.9 times higher than non-vascular intervention, who had both infection and artery occlusion was 17,522,435 won, 2.0 times higher than either infection or artery occlusion. Conclusion: In diabetic foot patients, the direct service cost was highest as 17,522,435 won in patients accompanied with both infection and occlusion of lower extremity artery.

Background: The first pain clinic opened in korea in 1973 at Yonsei University Hospital, however, since then the number of pain clinics has gradually increased, as has the number of patients visiting them. This increase in patient has caused concerns about the way in which pain is managed, therefore, we conducted a retrospective review of data according to the sex, age and disease in an attept to aid us in planning for the future of our pain clinic. Methods: We analyzed 1,282 new patients who had visited our pain clinic and 828 inpatients who were admitted to our pain clinic between March 2006 and February 2007. Results: The most frequent age group was in the sixties in outpatient and in the seventies in inpatient. In addition, the incidence of disease in new patients and inpatients was as follows: in new patients, lumbar herniated intervertebral disc 16.5%, hyperhidrosis 12.3%, cervical disc disorder 10.5%, acute herpes zoster 8.2%, postherpetic neuralgia 7.9%, and trigeminal neuralgia 7.0%; in admitted patients, acute herpes zoster 17.6%, trigeminal neuralgia 15.6%, lumbar herniated intervertebral disc 13.0%, postherpetic neuralgia 11.2%, hyperhidrosis 9.8%, and complex regional pain syndrome 7.0%. Conclusions: The patients visiting our pain clinic have presented with a wide variety of diseases. This improved care reflects an effort to expand our fields not only to the management of outpatients but also inpatients, as well as to the treatment of new fields of disease. In the future, We need to manage various pain patients not only in outpatients but also in inpatients to expand our field even through pain clinic is rapidly growing in Korea.

This study was conducted to investigate the changes in patterns of Daegu- and Gyeongbuk-based patients' use of medical care facilities located in Seoul. The 'Patient Survey' data issued by the Ministry of Health and Welfare for 2002, 2005, and 2008 were used. Among all discharged patients residing in Daegu and Gyeongbuk, 133,456 who used medical facilities in Daegu, Gyeongbuk, and Seoul were selected. Among patients residing in Daegu, 2.2% used medical facilities in Seoul in 2002, 3.7% in 2005, and 3.5% in 2008. The corresponding rates among patients living in Gyeongbuk were 5.6%(2002), 7.1%(2005), and 7.3%(2008). Regarding the ICD-10 disease groups, the use of medical facilities in Seoul by patients residing in either Daegu or Gyeongbuk increased in 2005 right after the introduction of the KTX high-speed train service, covering various disease groups, but decreased again in 2008. 'Neoplasm' cases, however, showed a progressive rising trend during the years studied. Multivariate data analysis for the three years showed that sex, age, payment type, hospital type, residence, year, and disease groups were all significantly associated with the utilization of medical facilities in Seoul. The major results are : First, use of medical facilities in Seoul by Gyeongbuk patients was 2.4-fold higher than that by Daegu patients, but with respect to 2005 and 2008 vs. 2002, use of medical facilities in Seoul by Daegu resident patients' showed a larger increase than that by Gyeongbuk's patients. Second, for patients residing in the two regions, use of medical facilities in Seoul was highest for 'congenital malformations, deformations and chromosomal abnormalities', followed by 'neoplasms'. Third, for patients residing in the two regions, general hospitals comprise the primary factor in the use of medical facilities in Seoul. The study shows that local medical facilities should individually exert more efforts to improve the quality of their medical services. Relevant authorities should likewise help these facilities develop their own unique services and respective specialization.
