Background: Breast cancer is the most common type of cancer amongst women throughout the world. Currently, there are various follow-up strategies implemented in Iran, which are usually dependent on clinic policies and agreement among the resident oncologists. Purpose: A cost-effectiveness analysis was performed to assess the cost-effectiveness of intensive follow-up versus standard models for early breast cancer patients in Iran. Materials and methods: This cross sectional study was performed with 382 patients each in the intensive and standard groups. Costs were identified and measured from a payer perspective, including direct medical outlay. To assess the effectiveness of the two follow-up models we used a decision tree along with indicators of detection of recurrence and metastasis, calculating expected costs and effectiveness for both cases; in addition, incremental cost-effectiveness ratios were determined. Results: The results of decision tree showed expected case detection rates of 0.137 and 0.018 and expected costs of US$24,494.62 and US$6,859.27, respectively, for the intensive and standard follow-up models. Tornado diagrams revealed the highest sensitivity to cost increases using the intensive follow-up model with an ICER=US$148,196.2. Conclusion: Overall, the results showed that the intensive follow-up method is not cost-effective when compared to the standard model.

Why does e-Learning service for individuals remain in the early development stage? To find the answers of this question, we adopted usefulness and intention to continued use as dependent variables based on technology acceptance model and inferred convenience, cost-effectiveness, social presence, interactivity, concentration, and procrastination as independent variables based on literature review and interview with e-Learning users. Convenience and cost-effectiveness of e-Learning tend to enhance usefulness and/or intention to continued use, while lack of social presence, interactivity, and concentration of e-Learning and academic procrastination tend to hinder usefulness and/or intention to continued use. To prove this research model, we used a data set collected from the survey. The respondents of survey were the undergraduate students who used voluntarily e-Learning. Data analysis was conducted using 275 respondents by partial least square. The analysis result of causal relation indicated that convenience and cost-effectiveness influenced both usefulness and intention to continued use, and that cost-effectiveness and concentration influenced only intention to continued use. But, interactivity and procrastination did not influence usefulness and intention to continued use.

Purpose: This study was a retrospective survey to examine economic feasibility of home care services for patients with diabetic foot. Methods: The participants were 33 patients in the home care services (HC) group and 27 in the non-home care services (non-HC) group, all of whom were discharged early after inpatient treatment. Data were collected from medical records. Direct medical costs were calculated using medical fee payment data. Cost-effectiveness ratio was calculated using direct medical costs paid by the patient and the insurer until complete cure of the diabetic foot. Effectiveness was the time required for a complete cure. Direct medical costs included fees for hospitalization, emergency care, home care, ambulatory fees, and hospitalization or ambulatory fees at other medical institutions. Results: Mean for direct medical costs was 11,118,773 won per person in the HC group, and 16,005,883 won in the non-HC group. The difference between the groups was statistically significant (p=.042). Analysis of the results for cost-effectiveness ratio showed 91,891 won per day in the HC patients, and 109,629 won per day in the non-HC patients. Conclusion: Result shows that the cost-effectiveness ratio is lower HC patients than non-HC patients, that indicates home care services are economically feasible.

Background: This study evaluated the cost-effectiveness of 21 different national dyslipidemia screening strategies according to total cholesterol (TC) cutoff and screening interval among 40 years or more for the primary prevention of coronary heart disease over a lifetime in Korea, from a societal perspective. Methods: A decision tree was used to estimate disease detection with the 21 different screening strategies, while a Markov model was used to model disease progression until death, quality-adjusted life years (QALYs) and costs from a Korea societal perspective. Results: The results showed that the strategy with TC 200 mg/dL and 4-year interval cost \4,625,446 for 16.65105 QALYs per person and strategy with TC 200 mg/dL and 3-year interval cost \4,691,771 for 16.65164 QALYs compared with \3,061,371 for 16.59877 QALYs for strategy with no screening. The incremental cost-effectiveness ratio of strategy with TC 200 mg/dL and 4-year interval versus strategy with no screening was \29,916,271/QALY. At a Korea willingness-to-pay threshold of \30,500,000/QALY, strategy with TC 200 mg/dL and 4-year interval is cost-effective compared with strategy with no screening. Sensitivity analyses showed that results were robust to reasonable variations in model parameters. Conclusion: In this study, revised national dyslipidemia screening strategy with TC 200 mg/dL and 4-year interval could be a cost-effective option. A better understanding of the Korean dyslipidemia population may be necessary to aid in future efforts to improve dyslipidemia diagnosis and management.

Background: In South Korea, 22.3% of women ${\geq}50years$ of age and 37% of women ${\geq}70years$ of age visit the doctor to obtain treatment for osteoporosis. According to the analysis of the National Health Insurance Services claim data between 2008 and 2012, the number and incidence of hip and vertebral fractures increased during the same period. Denosumab, a newly marketed medicine in Korea, is the first RANK inhibitor. Methods: A cost-utility analysis was conducted from a societal perspective to prove the superiority of denosumab to alendronate. A Markov cohort model was used to investigate the cost-effectiveness of denosumab. A 6-month cycle length was used in the model, and all patients were individually followed up through the model, from their age at treatment initiation to their time of death or until 100 years of age. The model consisted of eight health states: well; hip fracture; vertebral fracture; wrist fracture; other osteoporotic fracture; post-hip fracture; post-vertebral fracture; and dead. All patients began in the well-health state. In this model, 5% discounted rate, two-year maximum offset time, and persistence were adopted. Results: The total lifetime costs for alendronate and denosumab were USD 5,587 and USD 6,534, respectively. The incremental cost-effectiveness ratio (ICER) for denosumab versus alendronate was USD 20,600/QALY. Given the ICER threshold in Korea, the results indicated that denosumab was remarkably superior to alendronate. Conclusion: Denosumab is a cost-effective alternative to the oral anti-osteoporotic treatment, alendronate, in South Korea.

This study was performed to analyse the economic value of abciximab which is used in PCI to prevent high-risk patients with ischemic complications. The effectiveness of abciximab was extracted from published clinical trials by search-ing CCIS, and the direct medical costs relevant to using abciximab were estimated from the NHI claims database. The results in terms of cost per life-year gained (LYG) and cost per QALY gained showed that abciximab was cost-effective enough to deserve its cost. Social net benefit resulting from abciximab in PCI was estimated to be 60-70 billion Won per year.

Purpose : The aim of this study is to review cost analysis methodological issues in the nursing literature. Method : The subjects of this study were articles published in Korea from 1961 to August, 2002. They were searched by key words 'cost' and 'nursing' from various DB(National Assembly Library, The National Library of Korea, RICH etc). Finally, 31 articles were collected. Results : 1) The major type of cost analysis was a cost comparison study. 2) The important methodological weaknesses were as followers: First, many studies did not describe a cost analysis framework or a cost analysis assumption. Second, a few studies described selection criteria of cost items and effectiveness items. Third, many studies did not do a sensitivity analysis. Conclusion : With these results, it will be possible to develop a more proper cost analysis methodological framework and also to make an evaluation criteria for cost analysis nursing study.
