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 α 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 (R² =0.53) explained more of the variation in overall satisfaction then B questionnaire (R2=0.43) in outpatient survey. In inpatient survey, type B questionnaire (R²=0.40) explained, more of the variation in overall satisfaction than type A questionnaire (R² =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.

Objectives : To determine the relationships among quality, satisfaction, value and purchase intention in health care service. Methods : The data were gathered from out-patients who had used hospital services. They were asked to assess service quality, satisfaction, service value, and purchase intention. A total of 557 usable questionnaires were gathered. The data were analyzed using SAS version 6.12. The analysis methods employed in the study were confirmatory analysis and covariance structural analysis. Results : Service quality exhibited a significant and positive relationship with satisfaction, service value, and purchase intention. Furthermore, satisfaction had a significant and positive relationship with purchase intention. And finally, service value had a significant and positive relationship with both satisfaction and purchase intention. Based on these findings, it is evident that satisfaction was a mediator between service quality and purchase intention. Also service value played a mediating role between service quality and satisfaction. Conclusions : These results suggest that service quality is an antecedent of satisfaction and sonics value, and exerts a stronger influence on purchase intentions than satisfaction and service value do. Thus, managers may need to emphasize service quality in health care.

Objectives : Cervical cancer is the second most frequent cancer among women in Busan. The Pap smear test could have a significant effect on detecting cervical cancer, and enhancing their rate of use is an important strategy for reducing the incidence and mortality of cervical cancer. This study aimed to evaluate the factors associated with the past use of the Pap smear test in Korean women. Methods : A population-based survey was carried out in Busan between November 1999 and March 2000. 1,673 participants were randomly selected from 2,684 women in Busan, using a 2-stage cluster sampling method, and interviewed in their homes. Their socio-demographic characteristics, smoking, drinking, familial cancer history, Pap smear screening history, reproductive and menstrual factors, sexual habits and use of contraceptive methods data were collected by a trained interviewer using a questionnaire. The use of the screening test was defined by a self-report from the participants on how many times they had had a Pap smear test in their lifetime, and when they had received their latest examination. Results : Of the 1,673 respondents (62.3% response rate), 57.6% had had a Pap smear test during her life (mean number, 2.3). Among the health examination participants(1,064), 961(90.3%) reported having sexual experience and 70.9% of these had had a Pap smear test. In a multiple logistic regression analysis, statistically significant relationships were observed for age groups and the Pap smear test rate (odds ratio, OR for 35-44 years=2.45; OR for 45-54 years=3.41; OR for 55 years=2.60; reference, under 34 years). The married or cohabiting women were more likely to have used the Pap smear test than those separated or widowed (OR=1.73). Among the reproductive behavioral measures, the number of births (OR for 3 births=4.22; OR for 2 births=3.95; OR for 1 births=3.38; reference, 0 births) and husband's extra-marital affairs (OR=1.50) were associated with the rates of use of Pap smear tests. Conclusion : It appears that the most important contributing factors to cervical cancer screening were age, marital status and number of births. A positive association was also observed for the husband's extra-marital affairs. This study enabled us to systematically assess the relationship between Pap smear rates and risk factors for cervical cancer. It is hoped that this study will make a significant contribution to the accumulating scientific evidence on the identification of factors associated with cervical cancer screening in Korea.

Objectives : Cancer is the leading cause of death in Korea. Therefore, a National Cancer Screening Program (NCSP) was launched in 1999. This study planned to evaluate the performance of the NCSP to identifying the influencing factors in relation to characteristic public health centers. Methods : To analyze the performance, the database of the NCSP records for 2002 was used. The performance index was measured by the goal achievement rate, which was defined by the real number of screenees against the expected number of screenees. Also, a survey was conducted by a self-administered questionnaire to identify the factors associated with the goal achievement rate. The questionnaire was divided into two sections. In the first section, the individual characteristics of the program coordinator in each public health center were measured, and second section was comprised of questions about the organizational characteristics associated with the NCSP. A total of 121 subjects from 241 public health centers completed the questionnaire. Results : Of the 121 public health centers (50.2% response rate), the average goal achievement rate was 72.8%. The results of the regression model showed that public health centers located in rural area (parameter estimates=38.2) and had great support from a head of center or province (parameter estimates=0.20) and tended to have higher goal achievement rates. However, the characteristics of the program coordinator, especially their knowledge of and attitude toward cancer screening, were not significantly related to the goal achievement rates. Conclusions : It appears that the most important associated factors to the goal achievement rate in the NSCP were the location of the public health center and the support for the NCSP from the head of the center or province.

Background : To propose effective strategies for successful implementation of QI in health care institutions, by identifying facilitating factors and barriers to conducting QI programs. Methods : In order to examine empirical evidence on the success factors or barriers to QI implementation in hospitals, a literature study was performed on the basis of MEDLINE search. Among the identified literature. 13 provided reliable findings and basis comprehensive discussion on this issue and thus were selected for in-depth analysis. A mailed questionnaire survey was conducted for hospital CEOs and QI directors of hospitals with 400 beds or greater to investigate what attributes of their organizations they perceived as success factors or obstacles to QI implementation. Result : The analysis of selected literature and survey results presented that the primary factors considered to be most important as successful implementation of QI were: strong support from hospital CEOs, setting higher priority for QI activities, continuous and persistent efforts in QI activities, and active participation of clinical staffs. The barriers identified in this study were : the lack of orientation and understanding of QI concepts, low level of interest and participation of physician in QI programs, the lack of evaluation and rewarding system for QI activities. Conclusion : By identifying factors that affect facilitation of QI, the study results will be of great use for either institutions being in the early stage of evolving QI or those looking for better strategies to achieve more active and persistent QI implementation in their institutions.

Background : The purpose of this study was to investigate the understanding and the attitude of Korean hospital CEOs toward the healthcare quality improvement. Methods : A mailed questionnaire survey to the CEOs of hospitals with 400 beds or more was conducted between September 15 and October 30, 2000. Of the 108 hospitals eligible for the study, 58 participated, yielding a response rate of 54 percent. Result : The hospital CEOs have expressed that their hospital management was arduous job, and they had been pressured by increasing competitions among healthcare providers. They indicated that the low fees of health insurance made their hospital management difficult. The results also indicated that there was general consensus that the improvement of service quality was important in encouraging their organizations, but the investment of manpower and equipment ranked higher than the improvement of service quality. The majority of the CEOs have good understanding about quality improvement activities. However the facts that in general QI must be focused at the process of services and customer satisfaction, meanwhile quality improvement activities are helpful for the organizational productivity embarrassed them. The hospital CEOs responded that there were successful changes in terms of quality of care, patient satisfaction, and process efficiency after QI activities, but no increase in patient number and profit. Lack of understanding to QI activities and limited budget seem to attribute unsatisfactory outcomes. Conclusion : The majority of Korean hospital CEOs have a good understanding and attitude about QI activities. As mentioned in the result, despite of several limitations, several facts regarding the CEOs of hospital in Korean can be elucidated. (1)The general cognition of the QI project is relatively high, and it is accepted with positive concern, (2) the priority of the QI project, however, is not set higher than other projects and (3) the specific concepts of the actual QI project such as customer(patient)-focused work driving, the recognition of the work accomplishment, and the importance of rewards have not sufficiently understood.

The aim of this study was to compare medical cost of hospice care and that of conventional care during the last year of life, and identify factors that influenced the cost. From January to August 2003 592 terminal cancer patients receiving care from 5 hospice care units and 2 hospice care teams in general hospitals were enrolled to case group. Two hundreds and seventy two terminal cancer patients receiving conventional care from 7 general hospitals were enrolled to hospital‐based control group, and 1,636 terminal cancer patients from 122 general hospitals located in same regions with the 7 hospitals were enrolled to community‐based control. We used characteristics and medical cost from data of National Health Insurance Cooperation. Total medical cost per beneficiary in cases was about 10 millions won, 14.5 millions in hospital‐based controls and 11.1 millions in community‐based controls. The hospice care saved 45% over the last year of life compared with hospital‐based controls (p<0.0001). Saving of inpatient cost account for approximately 80% of saving per beneficiary. Hospice care saved 29% of medical cost per hospitalization day compared with hospital‐based controls and 17% compared with community‐based controls (p<0.0001). Multiple regression analyses showed that hospice care significantly saved the medical cost. This study suggest that hospice care save medical cost compared with hospital‐based control and community‐based control. Most of saving of inpatient cost account for approximately 80% of saving of medical cost.

Specifically, colorectal cancer in men is one of the most sharply increasing malignancies. The objective of this study was to assess the direct costs for colorectal cancer patients and to identify the factors that influence cancer costs. Methods: The direct costs of colorectal cancer were examined with a prospective group study at a hospital. The direct costs were assessed every 3 months over a 24-month period through patient interviews, medical records, and claims data. We identified the major factors associated with the cost of colorectal cancer by using a general linear model for the log-transformed data. Results: The group was comprised of 100 patients with colon cancer and 120 patients with rectal cancer. The average costs per patient during the first and the second years after diagnosis were ￦16,280,000 and ￦5,786,000, respectively. Medical costs accounted for about 68% (￦11,090,000) of the first year’s total cost and about 62% (￦3,602,000) of the second year’s total cost. National Health Insurance (NHI) paid approximately 50% of the total medical cost. The total cost of colorectal cancer was clearly associated with the stage of the disease at first diagnosis, the cancer site, therapeutic modalities, and recurrence. Conclusions: These results indicate that colorectal cancer has a heavy financial impact on cancer patients. The total cost of colorectal cancer is clearly associated with the stage of the disease at first diagnosis. Increased efforts in terms of prevention and early detection may assist in reducing the costs. 목적: 암 발생과 사망이 증가하고 있으며, 특히 남성에서 대장암 발생이 급격하게 증가하고 있다. 본 연구는 대장암 환자가 부담하는 직접비용을 추정하고, 이에 영향을 미치는 요인을 분석하였다. 방법: 일개 병원 대장암센터에 내원하여 대장암으로 치료받은 220명을 2년간 추적조사 하였다. 직접비용은 3개월마다 환자와의 인터뷰, 의료비 청구자료, 의무기록조사로 추계하였다. 로그치환된 선형회귀분석으로 직접비용에 영향을 미치는 요인을 파악하였다. 결과: 220명의 대장암 환자 중 100명은 결장암, 120명은 직장암이었다. 대장암 환자의 진단후 1년간 지출한 직접비용은 16,280,000원이었으며, 2년째 비용은 5,786,000원이었다. 이중 의료비가 62∼68%를 차지하였으며, 의료비 중 보험자 부담금은 50%였다. 환자의 진단 당시 병기, 위치, 치료유형, 재발 여부가 직접비용에 통계적으로 유의하게 영향을 미쳤다. 결론: 대장암 환자의 진단 후 1년간 직접비용은 16,280,000원으로 환자의 경제적 부담이 큰 것으로 조사되었다. 그러나 조기 대장암은 진행암에 비해 2배 이상 직접비용이 감소하였다.

Screening for Gastric Cancer: The Usefulness of Endoscopy

최귀선,서민아 대한소화기내시경학회 2014 Clinical Endoscopy Vol.47 No.6

Gastric cancer screening is common in countries with high prevalence rates of gastric cancer. However, data supporting the effectiveness of gastric cancer screening are lacking. Thus, the aim of this review was to examine the current evidence on gastric cancer screening. Herein, we reviewed radiographic and endoscopic tests as methods of gastric cancer screening. Previous cohort studies and case-control studies have demonstrated reduced gastric cancer mortality in study populations that had undergone gastric cancer screening with radiographic tests. Recently, a case-control study in Japan reported a 30% reduction in gastric cancer mortality when screening was undertaken via endoscopy. Also, endoscopic screening for gastric cancer exhibited higher sensitivity and specificity than radiographic screening. Moreover, most cost-effectiveness analyses on the best strategy for detecting early gastric cancer have generally concluded that endoscopy is more cost-effective than radiographic testing. Although data on the impact of endoscopy screening programs on gastric cancer mortality are limited, recent study results suggest that gastric cancer screening by endoscopy in average-risk populations performs better than radiography screening. Further evaluation of the impact of these screening methods should take into account cost and any associated reduction in gastric cancer mortality.
