RESUMO
High cost of medical care provided to the patients with duodenal ulcers requires improvement of treatment organization. This study is aimed at pharmacoeconomic evaluation of the efficacy of treating patients with duodenal ulcers. Two groups of patients were made up for the investigation. The first group was made up of patients who had undergone an individual antisecretory therapy based on intragastric pH-monitoring. The other group was made up of patients undergoing standard treatment without using intragastric pH-monitoring. Upon the comparison of the results in both groups, it was revealed that the "cost of illness" and "cost-efficacy" turned out to be lower in the group of patients where intragastric pH-monitoring for selecting individual antisecretory therapy was used.
