Objectives : The purpose of this study was to evaluate the reliability of questionnaire according to item arrangement on patient satisfaction questionnaire. Methods : We developed the two types of questionnaire with different item arrangement. In the first type (A), questions were arranged according to medical service dimensions. Questions in the second type (B) were arranged according to medical process. Both questionnaires were composed of six dimensions: physical environments, process, competence, courtesy, information giving, understanding patients. Measurements were performed on a 5-score Likert scale. In an outpatients and inpatient survey, total 777 patients answered the type A (outpatients: 257, inpatients: 128) or Type B (outpatients: 257, inpatients: 135). In order to compare the internal consistency of two types. Cronbach's ${\alpha}$ were calculated. Multiple regression analysis was also performed to know which type of questionnaire explain more of the overall satisfaction. Results : In outpatient survey, type A questionnaire showed higher internal consistency than B except physical environments dimension. Also in inpatient survey, type A had higer internal consistency than B in four dimensions(process, competence, courtesy, understanding patients). In the results of multiple regression analysis, type A questionnaire ($R^2$=0.53) explained more of the variation in overall satisfaction then B questionnaire ($R^2$=0.43) in outpatient survey. In inpatient survey, type B questionnaire ($R^2$=0.40) explained, more of the variation in overall satisfaction than type A questionnaire ($R^2$=0.33).But the difference of R was not significant in inpatient survey. Conclusion : The results of this study support that type A questionnaire has higer reliability in assessment of consumer satisfaction than type B.

Background: This study explored the relationship between hospital resources and services uses in outpatient/inpatient-based hospital service area (HSA) in Korea. Methods: Study hospitals included all acute care hospitals except tertiary hospitals. Inpatient and outpatient hospital claims from the Korean National Health Insurance (NHI) program in 2010 were used to identify the service uses. Hospital resources and the degree of insurance premium in study areas were identified with the NHI corporation data. Study variables were computed by summing the service uses or hospital resources of study hospitals in each HSA. Service uses were represented by the total medical charges and number of visits/inpatient days. Hospital resources were measured by number of beds, number of doctors, and number of computed tomography (CT). The economic status of NHI enrollees in each HSA was controlled by the average monthly premium of NHI program per household in each HSA. The degree of using local hospitals was controlled with the localization index. Results: Analysis results showed that hospital resources such as beds, CT were statistically related to the service uses. And also localization index was found to have positive significant relationships with service uses. Conclusion: Hospital resources such as beds, CT had not only positive impacts on inpatient service uses, but also influences on the outpatient setting. Health policy makers will require monitoring and assessing the hospital resources in Korea.

본 연구의 목적은 병원의 입원환자 진료서비스와 환자 재원일수와의 관계를 알아보기 위함이다. 병원 진료의 집중화 정도를 측정하기 위하여 진단명 기준 환자군(Diagnosis Related Group, 이하 DRG)을 이용하여 내부 허핀달 지수(IHI: Internal Herfindahl-Hirshman Index)를 산출하였다. 그 다음 병원 운영의 효율성에 미치는 영향을 분석하기 위하여 병원별 평균 재원일수를 종속 변수로 하여 분석하였다. 입원 진료 서비스의 집중화 정도와 재원 일수는 음의 상관관계로 집중화 정도가 높을수록 재원일수가 유의미하게 짧아지고 있다. 이는 다시 해석하면 입원 진료의 집중화 전략은 병원 운영 측면에서는 병상 회전율을 높여주고 환자 결과 측면에서는 건강성과에 긍정적인 영향을 주는 전략이라고 할 수 있다.

Background: The costliness index (CI) is an index that is used in various ways to improve the quality of medical care and the management of appropriate treatment in medical institutions. However, the current calculation method for CI has a limitation in reflecting the actual medical cost of the patient unit because the outpatient and inpatient costs are evaluated separately. It is desirable to calculate the CI by integrating the medical cost into the episode unit. Methods: We developed an episode-based CI method using the episode classification system of the Centers for Medicare and Medicaid Services to the National Inpatient Sample data in Korea, which can integrate the admission and ambulatory care cost to episode unit. Additionally, we compared our new method with the previous method. Results: In some episodes, the correlation between previous and episode-based CI was low, and the proportion of outpatient treatment costs in total cost and readmission rates are high. As a result of regression analysis, it is possible that the level of total medical costs of the patient unit in low volume medical institute and rural area has been underestimated. Conclusion: High proportion of outpatient treatment cost in total medical cost means that some medical institutions may have provided medical services in the ambulatory care that are ancillary to inpatient treatment. In addition, a high readmission rate indicates insufficient treatment service for inpatients, which means that previous CI may not accurately reflect actual patient-based treatment costs. Therefore, an integrated patient-unit classification system which can be used as a more effective CI indicator is needed.

Background/Aims: Colonic volvulus (CV), a common cause of bowel obstruction, often requires intervention. We aimed to identify hospitalization trends and CV outcomes in the United States. Methods: We used the National Inpatient Sample to identify all adult CV hospitalizations in the United States from 2007 to 2017. Patient demographics, comorbidities, and inpatient outcomes were highlighted. Outcomes of endoscopic and surgical management were compared. Results: From 2007 to 2017, there were 220,666 CV hospitalizations. CV-related hospitalizations increased from 17,888 in 2007 to 21,715 in 2017 (p<0.001). However, inpatient mortality decreased from 7.6% in 2007 to 6.2% in 2017 (p<0.001). Of all CV-related hospitalizations, 13,745 underwent endoscopic intervention, and 77,157 underwent surgery. Although the endoscopic cohort had patients with a higher Charlson comorbidity index, we noted lower inpatient mortality (6.1% vs. 7.0%, p<0.001), mean length of stay (8.3 vs. 11.8 days, p<0.001), and mean total healthcare charge ($68,126 vs. $106,703, p<0.001) compared to the surgical cohort. Male sex, increased Charlson comorbidity index scores, acute kidney injury, and malnutrition were associated with higher odds of inpatient mortality in patients with CV who underwent endoscopic management. Conclusions: Endoscopic intervention has lower inpatient mortality and is an excellent alternative to surgery for appropriately selected CV hospitalizations.

Objectives: This study aimed to. offer some fundamental evidences for the stroke management policy by investigating the trends of medical care utilization and regionalization in stroke inpatients. Methods: We used the National Health Insurance claims and registry data for stroke inpatients from 1998 to 2005. Among all stroke inpatient claims data, self-employed insured and their dependents were only included in this study. The classification of stroke was based on ICD-10(I60-I69) and its subtype was divided by hemorrhage(I60-I62) and infarction(I63-I64) type. To evaluate regionalization of medical care utilization, relevance index was calculated by regions. The regions were classified 8 large catchment areas and 163 self authorized areas. Results: The overall medical care utilization rate of stroke inpatient has been increased, especially infarction subtype. Among medical care institutions, the utilization of hospital has been the most rapidly increased. Although considered annual rate of interest, total medical cost of stroke inpatients has been increased, Totally, more than 84% of stroke inpatient were admitted to medical care institutions in their own large catchment area during 1998-2005. The relevance indices in their own large catchment area (self sufficiency rates) were more than 70% in most areas regardless of stroke subtype except Chungbuk catchment area. Self sufficiency rates of stroke inpatients among 163 self authorized areas in 1998 and 2005 were 84.2% and 83.1% in metropolitan, 46.7% and 45.5% in urban, and 19.5% and 22.6% in rural areas, respectively. Conclusion: Stroke management policy for improvement of distribution at the district level, especially in rural areas, may be helpful for reducing regional inequality in stroke.

Objectives: The purpose of this study was to analyze the medical cost of facial paralysis in payer perspective and to estimate the practice pattern of patient using 2011 Health Insurance Review & Assessment Service-National Patients Sample(HIRA-NPS). Methods: Basic statistical system was used for descriptive analysis of NPS dataset. A table for general information (table20) was extracted by disease code, and social demographic characteristics, distribution of the use among inpatients and outpatients, utilization of each kind of medical care institutions, medical cost were analyzed. Subgroup analysis was conducted for assuming the practice pattern of korean medicine and western medicine. Results: A total of 8,219 people and 64,345 claims data were identified as having facial paralysis. Proportion of outpatient was 95.23%, inpatient 0.84% and patient using both services 3.93%. Mean patient charges was 44,229 won per outpatient, 178,886 won per inpatient and 523,542 won per patient using both services. Utilization of korean medical care institutions was 68.81%(claims), 40.46%(patients), utilization of western medical care institutions was 31.19%(claims), 59.54%(patients). The amount charged by korean medical care institutions was 52.61% and western medical care institutions was 47.39%. Cost per claim was higher than those of the korean treatment and cost per patient of western treatment was lower than those of the korean treatment. Conclusions: The research assessed the medical cost and practice pattern associated with facial paralysis. These findings could be used in health care policy and subsequent studies.
