  • In medical research, the risk factors associated with human diseases need to be identified to predict the incidence rate and determine the treatment plan. Logistic regression analysis is primarily used in order to select risk factors. However, individuals who are unfamiliar with statistics outcomes have trouble using these methods. In this study, we develop a nomogram that graphically represents the numerical association between the disease and risk factors in order to identify the risk factors for delirium and to interpret and use the results more effectively. By using the logistic regression model, we identify risk factors related to delirium, construct a nomogram and predict incidence rates. Additionally, we verify the developed nomogram using a receiver operation characteristics (ROC) curve and calibration plot. Nursing home, stroke/epilepsy, metabolic abnormality, hemodynamic instability, and analgesics were selected as risk factors. The validation results of the nomogram, built with the factors of training set and the test set of the AUC showed a statistically significant determination of 0.893 and 0.717, respectively. As a result of drawing the calibration plot, the coefficient of determination was 0.820. By using the nomogram developed in this paper, health professionals can easily predict the incidence rate of delirium for individual patients. Based on this information, the nomogram could be used as a useful tool to establish an individual's treatment plan.

  • Accurate vital statistics are essential for a national health planning and evaluation. Among various vital statistics, birth and death rates, and infant and matemal mortality rates together with the causes of death are the very basic ones for above purposes as well as for the maternal and child health management. These statistics are based on the birth and death reports. It is required by law to report every birth and death within one month after its occurrence. However, in case of a neonatal death occurring prior to the birth report, most of the birth and death are not reported. Thus accurate infant and maternal mortality rates are not available yet in Korea. The main objective of this study is to develop a birth and infant death reporting system via computer network. We designed a new birth report form based on the current form and data from the analysis of medical record forms of 14 hospitals. A new form is basically addition of essential medical information to the current birth report form. Since a revision of the rules and regulations related wtih the birth report is necessary to use a new form, we kept the current from intact to make it acceptable to the government office for a field trial. We also developed computer programs for data input for birth and death reports at a medical faciltiy, data processing for production of maternal and child health indices at a health center, and management of maternal and child health services including immunization and postantal care at health center. The birth certificate and birth report can be printed out at a medical facility. The computer packages were programmed by Borland Delphi 3.0 and can be run under Windows 95 system. We proposed a new birth and death reporting system via computer network after a field trial for data input, transmission, and processing. The medical and demographic data o birth and death at medical facilities will be sent to health centers directly via computer network. The health center will retain the medical data for analysis and forward only the data for birth and death reports required by current regulations to the Dong, Up, or Myun Office. Once the birth or death is reported via computer network to the Dong Office, then the Dong Office will notify the baby's mother of the birth report and request to submit the baby's name by mail. When the baby's name its submitted. the Dong Office will forward the birth reports to the Common Court and Statistics Agency in the same way as the current system, Upon the completion of birth registration of the Common Court, the court will issue the birth certificate to mother which will be used in lieu of the family record. The advantages of proposed birth and death reporting system via computer network ar as follows ; I) The accuracy, timing, and completeness of reporting will be improved and more accurate maternal and child health indices can be obtained, ii) The maternal and child health services of health center will be obtained, iii) Epidemiologic data for pregnancy and birth can be obtained, iv) Manpower for birth and death reporting will be saved.

  • 손상부담은 우리사회에서 매우 심각한 것으로 널리 인식되고 있다. 그럼에도 불구하고 손상감시에 필요한 데이터가 충분하지 않다. 이 연구의 목적은 손상감시를 위해 핵심 데이터를 선택하고 보완하는 것이다. 이를 위해 본 연구에서는 통계품질 6가지 차원에 따라 '사망원인통계', '건강보험통계', '퇴원손상조사'에 대한 품질평가보고서 등의 문헌을 분석 하였다. 분석결과는 '사망원인통계'와 '건강보험통계'가 손상감시를 위한 핵심데이터로서 유용성이 있다는 것이다. 그러나 '건강보험통계'에는 손상외인에 대한 데이터가 부족하다는 단점이 있다. 단점을 보완하기 위해, 본 연구에서는 국민건강보험 의료비 청구 시 의료기관이 손상외인을 의무적으로 신고하도록 하는 제도를 제안한다. 이 제도의 결과로서 우리는 '손상 피라미드 구축', '국민연금과의 데이터 연계', '손상 데이터의 시의성 향상'을 기대할 수 있다. 그리고 이 제도 실현을 위한 후속 연구를 기대한다.

  • Purpose: The purpose of this study was to evaluate the effectiveness of case management for patients with hypertension on their health status and medical service utilization. Methods: This study was a secondary analysis of data collected for a larger study of chronic disease management in 2008 using the National Health Insurance Corporation database. A total of 12,944 patients who received case management for hypertension were included in this analysis. The subjects of case management were classified into subgroups, namely, over-use, under-use, and non-use groups according to the amount of medical service utilization. To compare the medical service utilization, a control group was selected randomly. The data were analyzed through descriptive statistics, McNemar test, and ANOVA. Results: All the subgroups displayed significant differences in blood pressure, self-management, social support, and their characteristics of medical service utilization. The total medical expense of the under-use and non-use groups increased after case management. However, there was no decrease in the medical expense of the over-use group. Conclusion: This finding suggests that there is a need to re-examine why patients overuse medical services and to supplement specific strategies for encouraging appropriate medical service utilization, and enhancing case management efforts for the over-use group.

  • Purpose: The purpose of this study was to investigate experiences of violence with patients or family members by paramedics working at emergency rooms. Methods: A questionnaire was administered from June 1 to 31, 2017 to 225 paramedics working at 27 emergency medical centers. The collected data were analyzed with SPSS statistics ver 24.0 program. Results: Within the past year, 208(92.9%) of 224 participants experienced violence among whom 202(90.2%) experienced verbal abuse, 193(86.2%) experienced physical threat, 89(39.7%) experienced physical violence, and 52(23.2%) experienced sexual violence. The level of violence response depending on the overlapping experience of violence type showed significant difference from emotional response (p= .001), social response (p= .001), physical response (p= .004), and overall violence response (p= .001). Conclusion: In conclusion, paramedics are frequently exposed to violence in the emergency rooms, of which they mostly experience verbal abuse. In addition, because the reporting system in the event of violence and the coping process are not well-informed, paramedics are unable to sufficiently utilize the reporting system and programs established within the institution. Therefore, the support of the legal system is needed to create a safe working environment for the medical staff who work in the emergency medical centers.

  • A self directed learning(SDL) has been identified as an important ability for medical graduates. The purpose of this study was 1) to measure the SDLR of medical students, 2) to compare the relationship among the student perceptions of assessment, preference of instructional methods with SDLR. This study was conducted in 2006 at A University College of Medicine. The instrument applied to this study was SDLR. Korean version of Guglielmino's SDLR for Adults. The $SPSSwin^{(R)}$ program was used to analyze the data and statistics such as correlation. F-test, and Chi square test. Firstly. the mean scores of the SDLR of first, second. fourth year were 114.8, 107.9 and 106.2. This results showed a significant relationship among years (p<.001). Secondly the relationship between the student perceptions of assessment and SDLR was insignificant. The SDLR high scores students had a tendency to favorite "Discussion" and "Bedside teaching". This study found out the problems of medical education to enhance self directed learning ability for medical students. Further study is needed so that suitable instructional methods for medical students can be conducted in curriculum.
