Objectives : This study was conducted to elicit quality weights for 42 EQ-5D health states with the time trade-off (TTO) method from the general population of South Korea. Methods : We selected the same EQ-5D health states as those in the UK MVH study. The Korean version of EQ-5D questionnaire and TTO method were used for the valuation process. We interviewed 500 people as a representative sample of the general population in Seoul and Gyeonggido. The result was compared with those from UK, Japan, and USA by Spearman's rank correlation and t-test. Results : TTO values for 42 EQ-5D health states and 'unconscious' state were obtained from the general South Korean population. The best one was '11112' state and the worst one was 'unconscious' state. The states worse than death were '33323', '33333', and 'unconscious' states, which had negative TTO values. There was a strong correlation between TTO values of the EQ-5D health states and those of their corresponding states from UK, Japan, and USA (Spearman's correlation coefficient: 0.885, 0.882, and 0.944, respectively, p <0.001). However, absolute TTO values of most EQ-5D health states were significantly different from those of their corresponding states in other foreign studies (UK : 41/42, USA : 32/42, Japan : 15/17). Conclusions : We found that the Korean general population TTO values for EQ-5D health states were different from those of other foreign studies, suggesting that a specific Korean valuation set should be developed and used for economic evaluation studies in South Korea.

Objectives: The objective of this study was to perform a systematic review and meta-analysis of pharmacopuncture treatment for insomnia disorder to derive clinical evidence and recommendation grades. Methods: Studies that verified effects of pharmacopuncture on primary insomnia were included. Characteristics and quality of included studies were assessed using Risk of Bias (RoB). Results: A total of 25 studies were selected. Pittsburgh Sleep Quality Index (PSQI) and effective rate were primarily used for outcome measurement. Vitamin B12 was the most used pharmacopuncture material. The most frequently used acupuncture point was Anmian (Ex-HN). The volume of the acupuncture solution ranged from 0.25 mL to 2 mL. Acupuncture treatment depth was 0.5 cm to 2 cm. In three studies, the procedure was performed at 16:00. Meta-analysis of studies revealed that the effective rate of the pharmacopuncture group was significantly higher than the group using sleeping pills group (RR: 1.21, 95% CI: 1.01 to 1.45, p=0.04, I²=69%). PSQI was decreased in the intervention group (MD=-2.19, 95% CI: -2.90 to -1.48, p<0.00001, I²=0%). Effective rates of pharmacopuncture and acupuncture groups were higher than that of the acupuncture group (RR: 1.11, 95% CI: 1.05 to 1.17, p=0.0002, I²=0%). PSQI was decreased in the intervention group (MD=-1.87, 95% CI: -2.36 to -1.38, p<0.00001, I²=0%). Although the effectiveness rate of the pharmacopuncture group was not significantly higher than that of the acupuncture group (RR: 1.12, 95% CI: 0.98 to 1.27, p=0.1, I²=9%), the PSQI was decreased in the pharmacopuncture group (MD=-2.10, 05% CI: -3.29 to -0.91, p=0.0005, I²=34%). The quality of clinical studies was poor. Conclusions: Based on results of this study, it is proper to use 0.5 to 2 mL of pharmacopuncture solution such as Danshen and Ciwujia with a depth of 0.5 to 2 cm at around 4 p.m. to treat insomnia disorder, focusing on Anmian (Ex-HN) and Sameumgyo (SP6).

Measurements of health related quality of life can be used to compare patients with specific conditions to average individuals in the general population in a similar age and gender group. However there are few data available regarding health related quality of life for the general population of Korea. Therefore, this study was conducted to examine the validity of the Korean version of EQ-5D and to measure the health related quality of life of the general adult population in a metropolitan city. The survey was cross-sectional and employed a stratified and multistage sampling design through 100 examination sites in 5 districts of Ulsan. A total of 12,644 individuals from 4,112 households participated in the survey. Of these, we analyzed data from 8,068 adults who were over 19 years old and completed the EQ-5D. To examine the validity of the questionnaire, the differences in 5 dimensions and the EQ-5Dindex were analyzed with regard to demographic and socioeconomic factors such as sex, age, income, and education. In addition, visual analogue scales (VAS) were used to evaluate the overall health related quality of life issues of the respondents. The level of health related quality of life of the general adult population was then compared with the results from the third Korean National Health and Nutrition Examination Survey and other countries. There were a small number of people with problems related tomobility, self-care, and usual activity. In addition, many people complained ofpain/discomfort and anxiety/depression. The complaint rate in each dimension, VAS, and EQ-5Dindex indicated relatively better states for males, the younger group, the higher income group, and the higher education group. In addition, the level of health related quality of life of the general population of Ulsan was relatively higher than that of Koreans nationwide as well as the populations of other countries. EQ-5D provided a valid measure of the health-related quality of life of the general adult population. In addition, the results of a survey of Ulsan revealed that the quality of life of its population is better than that of the overall population of Korea and of the populations of other countries.

목적: 뇌졸중으로 인한 장애인이 증가하고 있으나 이들을 대상으로 질보정수명을 구한 연구가 없었다. 이 연구의 목적은 일개 시에서 뇌졸중 장애인을 대상으로 EQ-5D로 그들의 건강 관련 삶의 질 수준을 평가하고, 우리나라 전체 뇌졸중 장애인의 QALYs 감소분을 추정하기 위하여 수행하였다. 방법: 2008년 3월을 기준으로 경주시 장애인 등록현황에서 50세 이상인 장애인 중 뇌졸중이 원인으로 파악된 982명을 대상으로 설문조사자들이 방문하여 대면면접조사를 통해 일반적 특성, 임상적 특성, EQ-5D 등의 자료를 수집하였다. 제4기 국민건강영양조사 에서 일반인구집단과 동반질환이 없는 군을 건강비교군으로 선정하여 성별, 연령별 표준화를 통해 비교함으로써 효용 가중치 차이를 구하였다. 이 효용 가중치 차이를 우리나라 전체 뇌졸중 장애인에 적용하여 전체 QALYs 감소분을 추정하였다. 결과: 대상자 982명 중 조사응답자는 566명으로 응답률은 57.6%였다. 여성, 70대 이상군에서 EQ-5D 지표값이 남성이나 60대 이하군에 비해 더 낮았고, 상대 비교군과의 차이도 크게 나타났다. 건강비교군과 일반인구집단 비교군과의 비교에 따른 전체 QALYs 감소분은 각각 연간 67,011.6 QALYs와 54,167.1 QALYs로 추정되었다. 결론: EQ-5D로 우리나라 전체 뇌졸중장애인의 QALYs 감소분을 추정하였고, 이 연구를 바탕으로 뇌졸중 장애인을 대상으로 한 공중보건정책의 집행이나 평가를 수행하여 보다 근거에 기반한 장애인 정책을 수행할 수 있을 것으로 생각한다. The purposes of this study were to measure health related quality of life (HRQOL) of persons disabled by stroke dwelling in Gyeongju-si using EQ-5D and to estimate total QALYs loss of persons disabled by stroke in Korea. The eligible subjects were 982 persons with stroke aged 50 and over in Gyeongju-si disabled registry, as of March, 2008. Interviewers measured HRQOL of study subjects using EQ-5D. EQ-5D index, utility weight, was derived from the Korean valuation set. In order to compare the results of this study, we selected two comparison groups representing Korean healthy population and general population of Korean using the 4th Korean National Health & Nutrition Examination Survey. Finally, after age and gender standardization, we estimated the total QALYs losses of persons disabled by stroke in Korea. Of 982 eligible subjects, 566 persons participated in the survey (response rate: 57.6%). In both of female and male, utility weights in the 70s or 80s were lower than those of the 50s or 60s. Utility weights differences among persons with disability, general population, and healthy population in male were larger than those differences in female. Total estimated QALY losses of persons disabled by stroke were 67,011.6 QALYs lower than healthy control groupand 54,167.1 QALYs lower than general population, respectively.

강민수(Min-Soo Kang),조민우(Min-Woo Jo),임현술(Hyun-Sul Lim),김상규(Sang-Kyu Kim) 한국농촌의학 지역보건학회 2010 농촌의학·지역보건 Vol.35 No.4

이 연구는 뇌졸중으로 장애진단을 받은 환자들을 대상으로 보건서비스를 제공하기 위한 사전조사와 뇌졸중 발생 및 장애정도와 관련된 요인을 분석하여 뇌졸중 예방과 장애를 최소화하기 위한 목적으로 실시하였다. 뇌졸중 환자에서 중증장애 발생은 연령이 증가할수록, 의료기관 도착시간이 3시간 이내 보다 6시간 초과 12시간 이내로 지연되는 경우 1.81배 증가하였고 뇌졸중 관련 만성질환이 없는 경우보다 만성질환이 2개 이상 있는 경우 0.57배 감소하였다. 뇌졸중에 대한 교육유무는 중증장애에 영향이 없었지만, 뇌졸중 발생 전 뇌졸중 관련 교육 유경험자 비율이 3.2%로 적었다. 향후 뇌졸중으로 인한 개인적, 사회적 비용을 줄이고 장애를 최소화하기 위해서는 발병 후 급성기에 효과적인 치료를 위한 뇌졸중환자 응급의료체계 구축과 함께 지역사회 뇌졸중환자와 고위험군을 대상으로 의료기관 도착 전 지연시간을 줄이기 위한 보건교육 등의 중재프로그램 개발이 필요한 것으로 판단된다. Objectives: This study was conducted to evaluate factors related to the degree of disability of stroke patients in a rural community. Methods: The study subjects included 641 patients selected from 975 stroke patients over the age of 50 with brain lesion-relateddisabilities living in Gyeongju, Korea, an urban-rural consolidated community. The data were obtained by interviews from July to October 2008. The subjects were divided into a seriously disabled group (1st and 2nd disability grade) and mildly disabled group (3th, 4th, 5th and 6th disability grade) by degree of disability according to registered disability grade. The collected data were analyzed using the SPSS 14.0 statistical package. Results: The study subjects included 379 males (59.1%) and 262 females (40.9%), and most patients were in their 70s (256 cases, 39.9%). The seriously disabled group included 287 patients (44.8%) and the mildly disabled group included 354 persons (55.2%). Age, prehospital delayed time and number of related chronic diseases were risk factors for serious disability (p<0.05). Conclusions: Our results indicate that the degree of disability can be reduced by decreasing prehospital delayed time. We suggest that education of high risk groups and establishment of emergency services as well as a transport system for stroke patients are required to reduce the degree of disability due to stroke.

Objectives : To develop a Diagnosis-Related Group (DRG) fraud candidate detection method, using data mining techniques, and to examine the efficiency of the developed method. Methods ; The Study included 79,790 DRGs and their related claims of 8 disease groups (Lens procedures, with or without, vitrectomy, tonsillectomy and/or adenoidectomy only, appendectomy, Cesarean section, vaginal delivery, anal and/or perianal procedures, inguinal and/or femoral hernia procedures, uterine and/or adnexa procedures for nonmalignancy), which were examined manually during a 32 months period. To construct an optimal prediction model, 38 variables were applied, and the correction rate and lift value of 3 models (decision tree, logistic regression, neural network) compared. The analyses were peformed separately by disease group. Results : The correction rates of the developed method, using data mining techniques, were 15.4 to 81.9%, according to disease groups, with an overall correction rate of 60.7%. The lift values were 1.9 to 7.3 according to disease groups, with an overall lift value of 4.1. Conclusions : The above findings suggested that the applying of data mining techniques is necessary to improve the efficiency of DRG fraud candidate detection.
