To evaluate the socio-economic effects of Helicobacter pylori eradication in the treatment of duodenal ulcer disease in Japan, a clinical decision analysis was performed to assess H. pylori eradication therapy compared with the conventional strategy of maintenance with histamine-2 receptor antagonists. A decision tree-based state transition model (Markov(More)
This study compares the cost effectiveness of Helicobacter pylori eradication and conventional treatment in duodenal ulcer patients treated by a general practitioner. Using a Markov chain approach, Swedish cost data and a study period of 5 years, we conclude that H. pylori eradication with omeprazole and appropriate antibiotics is a cost-effective(More)
One of the most serious sources of potential bias when using the contingent valuation (CV) method to assess willingness to pay (WTP) is implied-value cues, i.e., different types of starting-point bias. The possible existence of starting-point bias is serious, since it may be interpreted to mean that the responders' preferences are very unstable. While the(More)
Escalating medical costs have made it increasingly important to carry out economic evaluations of drug therapy. In the area of acid-related diseases, much of the current interest is focused on comparisons between omeprazole and H2 receptor antagonists. After having discussed the basic methodology used in these analyses, viz. the decision-tree analysis, this(More)
PURPOSE To describe the demographics, comorbidity, and health care resource utilization, as well as treatment patterns among gastroesophageal reflux disease (GORD) patients. METHODS We identified a population-based cohort of newly diagnosed GORD patients receiving cimetidine, ranitidine or omeprazole. Our final study population consisted of 1193 patients,(More)
OBJECTIVE This 1-year study compared the cost effectiveness of omeprazole and ranitidine when used as initial therapy in an intermittent treatment strategy for the management of patients with symptomatic gastro-oesophageal reflux disease with or without erosive oesophagitis. DESIGN AND SETTING A prospective health economic analysis was conducted alongside(More)
OBJECTIVES To investigate the marginal cost-effectiveness of different targets for the reduction of blood pressure and the cost-effectiveness of adding acetylsalicylic acid (ASA) to the treatment of hypertension. DESIGN Patients with hypertension were randomized to three target groups for blood pressure; < or =90, < or =85 and < or =80 mmHg. Patients were(More)
It has been suggested that an open-ended follow-up question should be added to the binary contingent valuation question. Before this is generally recommended, it is important to evaluate the properties of such follow-up questions. Using a split sample approach, we test whether the open-ended follow-up is sensitive to the scope of the commodity being valued.(More)
BACKGROUND Antireflux surgery is a highly effective treatment option in patients with severe gastro-oesophageal reflux disease. However, because of the increasing pressure of cost containment within health care, cost aspects must also be added to the decision-making process. METHODS The aim of this analysis was to assess the total cost of open antireflux(More)
