  • Background: Issues concerning with the classification accuracy of Korean Outpatient Groups (KOPGs) have been raised by providers and researchers. The KOPG is an outpatient classification system used to measure casemix of outpatient visits and to adjust provider risk in charges by the Health Insurance Review & Assessment Service in managing insurance payments. The objective of this study were to refine KOPGs to improve the classification accuracy and to evaluate the refinement. Methods: We refined the rules used to classify visits with multiple procedures, newly defined chemotherapy drug groups, and modified the medical visit indicators through reviews of other classification systems, data analyses, and consultations with experts. We assessed the improvement by measuring % of variation in case charges reduced by KOPGs and the refined system, Enhanced KOPGs (EKOPGs). We used claims data submitted by providers to the HIRA during the year 2012 in both refinement and evaluation. Results: EKOPGs explicitly allowed additional payments for multiple procedures with exceptions of packaging of routine ancillary services and consolidation of related significant procedures, and discounts ranging from 30% to 70% were defined in additional payments. Thirteen chemotherapy drug KOPGs were added and medical visit indicators were streamlined to include codes for consultation fees for outpatient visits. The % of variance reduction achieved by EKOPGs was 48% for all patients whereas the figure was 40% for KOPGs, and the improvement was larger in data from tertiary and general hospitals than in data from clinics. Conclusion: A significant improvement in the performance of the KOPG was achieved by refining payments for visits with multiple procedures, defining groups for visits with chemotherapy, and revising medical visit indicators.

  • The principal objective of the present study was to survey the demands of an education program for evaluations of the efficacy of health functional foods. A questionnaire was developed and sent to 2,225 members of the Biofood Network Center. A total of 101 (4.6%) individuals responded, 54.5% of the respondents were male and 45.5% were female; the respondents' occupations (in order of prevalence) were as follows: company worker (48.5%)>researcher (27.7%)>student (13.9%)>professor (5.0%)>pharmacist (2%), and dietitian (2%). The businesses in which the respondents worked were (again in order of prevalence) as follows: research & development (64.4%)>marketing (11.9%)>consultation and education (5.9%)>manufacturing and others (17.9%). 41.6% of the respondents reported experience in businesses relevant to KFDA approval for functional ingredients and health functional foods. The results showed that 63.4% of the respondents had previously been educated about functional foods; the types of education program reported were (in order of prevalence): 'overview and acts of health functional food' (n=49)>'standards and specification for health functional food' (n=41)>'efficacy evaluation-human study' (n=24)>'safety evaluation' (n=21)>'efficacy evaluation-in vivo study' (n=13)>and 'others' (n=10). Respondents preferred off-line education programs (62.4%) to on-line programs (22.8%). The preferred duration of an educational program was '$2{\sim}3$ days: total $14{\sim}24$ hours' (30.7%); thus, short-term programs were favored. The primary requirements of a program, from the perspective of the learner, were as follows (scored on a 7-point scale); 'efficacy evaluation and case study-human study' (5.80 points)>'standards and specification for health functional food' (5.72 points)>safety evaluation' (5.7 points)>'overview and acts of health functional food' (5.67 points) and 'efficacy evaluation methods of health functional food by efficacy (intensive)' (5.67 points). Preference for functionality was as follows; 'body weight & body fat' (21.8%), 'immune function' (18.8%) > 'blood glucose' (10.9%). In summary, the educational demand for 'efficacy evaluation and case study' was highest among the curriculum options provided, and with regard to functionality, 'body weight & body fat', 'immune function' and 'skin care' were considered most important by respondents. These results differed among respondents with different jobs and duties, and this suggests that customized education programs for health functional food should be developed.

  • Food preservatives are very important food additives for the biological and chemical safety of processed foods. The purposes of this study were to investigate Korean consumer's perception and information needs on food preservatives, to develop an educational booklet as a risk communication material on food preservatives, and to assess the educational effect of the developed booklet. To understand perception on food preservatives, a self-administered questionnaire survey was conducted by 381 parents having elementary school students at Seoul and Geoynggi area in Korea. Based on the survey results, brain storming of the authors along with consultation from the professionals, we developed a risk communication booklet about food preservatives. It was exposed to 35 parents of elementary school children, and their evaluation was collected by using a questionnaire and analyzed statistically. Respondents considered food safety (44.8%) as the most important factor while purchasing processed foods. They still perceived food additives as the most hazardous one (41.5%), and among those, food preservatives were the most concerned (45.9%). Total 67.7% of the respondents considered the consumption of food preservatives as hazardous or very hazardous. However, 90.6% of respondents did not have any educational experience about food additives and food preservatives. Based on their information needs, a science-based booklet consisting of the definition, classification, safety, intake, and management of food preservatives was developed. When the booklet titled as 'Food preservatives, Just Know Them!' was exposed to the parents via elementary school teacher, their negative perceptions on food additives and food preservatives were changed positively by increasing the understanding level on preservatives from 18.9% to 90.9% and obtaining 72.7% positive answers on their safety. Therefore, it could be used as an effective risk communication material on food preservatives.

  • The main purpose of the study is to identify critical risk factors for development of a family assessment tool to screen high risk family. This study used a conceptual framework of family diagnosis developed by Eui-sook Kim's (1993) and analyzed risk factors to identify the high risk family. As employing a explorative and methodological study design, this study has four stages. 1. In the first stage, 34 family risk factors were identified by doing intensive literature review on conceptual framework of family diagnoses. 2. In the second stage, above risk factors were tested for content validity by consultation with 29 persons in community health nursing, nursing education, family theory, and social work. 3. In the third stage, existing survey data was used for actual application of the identified risk factors. The survey data used for this purpose was previously collected for the community diagnosis in a region of Seoul. At the final stage, through the comparison between high risk and low risk families, initially identified 34 risk factors decreased to 25 risk factors. Among 34 risk factors, six factors did not agree with content of questionnaries sand two factors were not significant in differentiating the high risk family Also, two risk factors showed high correlation between themselves, so only one of those two factors was chosen. As a result, twenty-five risk factors chosen to identify the high risk family are following ; 1. A single parent family due to divorce or death of a partner, or unweded single mother 2. A family with an unrelated household members 3. A family with a working mother with a young child 4. A family with no regular income 5. A family with no rule in family or too strict rules 6. A family with little or no support from other lam-ily members 7. A family with little or no support from friends or relatives 8. A family with little or no time to share with each other 9. A family with family history of hypertension, diabetus, cancer 10. A family with a sick person 11. A family with a mentally ill person 12. A family with a disabled person 13. A family with an alcoholic person 14. A family with a excessive smoker who smokes more than 1 pack / day 15. A family with too much salt intake in their diet. 16. A family with inappropriate management skills for family health 17. A family with high utilization of drug store than hospital to solve the health problems of the family 18. A family with disharmony between husband and wife 19. A family with conflicts among the family members 20. A family with unequal division of labor among family members 21. An authoritative family structure 22. A socially isolated family 23. The location of house is not residential area 24. A family with high risk of accidents 25. The drinking water and sewage systems are not hygienic. The main implication of the results of this study is clinical use. The high risk factors can be used to identify the high risk family effectively and efficiently. The use of high risk factors woule contribute to develop a conceptual framework of family diagnosis in Korea and the list of risk factors need to be revised continuously. Further researches are needed to develop an index of weight of each risk factor and to validate the risk factors.

  • The existing Extracorporeal membrane oxygenation(ECMO) and Cardiopulmonary bypass system(CPB) have been developed and applied to various devices according to their respective indications. However, due to the complicated configuration and difficult usage method, it causes inconvenience to users and there is a risk of an accident. Therefore, smart all-in-one cardiopulmonary circulation device is being developed recently. The smart all-in-one cardiopulmonary assist device consists of a blood pump for cardiopulmonary bypass, a blood oxidizer for cardiopulmonary bypass, a blood circuit for cardiopulmonary bypass, and an artificial cardiopulmonary device. It is an integrated cardiopulmonary bypass device that can be used for a variety of purposes such as emergency, intraoperative, post-operative intensive care, and long-term cardiopulmonary assist, combined with CPB used in open heart surgery and ECMO used when patient's cardiopulmonary function does not work normally. The smart all-in-one cardiopulmonary assist device does not exist as a standard and international standard applicable to advanced medical devices. Therefore, in this study, we will refer to the International Standard for Blood Components, the International Standard for Blood, the Guideline for Blood Products, and prepare applicable performance and safety guidelines to help quality control of medical devices, and contribute to the improvement of the health of people. The guideline, which is the result of conducted a survey of the method of safety and performance test, is based on the principle of all-in-one cardiopulmonary aiding device, related domestic foreign standards, the status of domestic and foreign patents, related literature, blood pump(ISO 18242), blood oxygenator (ISO 7199), and blood circuit (ISO 15676) for cardiopulmonary bypass.The items on blood safety are as follows: American Society for Testing and Materials ASTM F1841-97R17), and in the 2010 Food and Drug Administration's Safety Assessment Guidelines for Medical Assisted Circulatory Devices. In addition, after reviewing the guidelines drawn up through expert consultation bodies including manufacturers / importers, testing inspectors, academia, etc. the final guideline was established through revision and supplementation process. Therefore, we propose guidelines for evaluating the safety and performance of smart all-in-one cardiopulmonary assist devices in line with growing technology.

  • Objectives : Delirium is a disorder defined as a sudden disturbance in thinking, speaking, acting and sleep pattern due to altered level of consciousness and cognitive function. The objective of this study is to analyze characteristics and therapeutic methods of the delirious patients during the recent 5 years, and provide basic data for further studies and investigation regarding delirium in the occurrence and treatment. Methods : We retrospectively reviewed medical records of 475 patients who were consulted for delirium in Kyunghee University Medical Center from January 2007 to December 2011. Results : During the 5 years, among the 475 patients who were diagnosed as delirium, men were more common(61.7%). The most commonly consulted reason and cause were sleep disturbance(80.8%) and post-operational delirium(30.9%), respectively. The medication prescription percentage was 76.6% and was significantly increased year after year. Ratio of using antipsychotics were 76.4% among prescribed medication and the most frequently prescribed antipsychotic drug was quetiapine(46.8%). Other specialists commonly misdiagnosed delirium when the patient was previously diagnosed as dementia(6.8%). Conclusions : In our study, post-operational delirium was the most commonly referred reason and the percentage of medication prescription tended to increase. Patients with history of dementia were more easily misdiagnosed as diseases other than delirium. Our study suggests that we should evaluate symptoms, causes, reasons of consultation, management tendency of delirium. We should also closely observe changes in sleep patterns and establish the prevention strategies for post-operational delirium and therapeutic bases for pharmacotherapy.
