economic evaluation of test-and-treat and empirical treatment strategies in the eradication of helicobacter pylori infection; a markov model in an iranian adult population

background: helicobacter pylori may cause many gastrointestinal problems in developing countries such as iran. we aimed to analyze the cost- effectiveness and cost- utility of the test-and-treat and empirical treatment strategies in managing helicobacter pylori infection.            methods: this was a markov based economic evaluation. effectiveness was defined as the symptoms free numbers and qalys in 100,000 hypothetical adults. the sensitivity analysis was based on monte carlo approach.     results: in the test- and- treat strategy, if the serology is the first diagnostic test vs. histology, the cost per symptoms free number would be 291,736.1 rials while the cost per qalys would be 339,226.1 rials.  the cost per symptoms free number and cost per qalys when the 13 c-ubt was used as the first diagnostic test vs. serology was 1,283,200 and 1,492,103 rials, respectively. in the empirical strategy, if histology is used as the first diagnostic test vs. 13 cubt, the cost per symptoms free numbers and cost per qalys would be 793,234 and 955,698 rials, respectively. if serology were used as the first diagnostic test vs. histology, the cost per symptoms free and qalys would be 793,234 and 368941 rials, respectively.   conclusion: there was no significant and considerable dominancy between the alternatives and the diagnostic tests.
