IJERPH, Vol. 19, Pages 9986: Cost-Effectiveness Analysis of the Helicobacter Pylori Screening Programme in an Asymptomatic Population in China (International Journal of Environmental Research and Public Health)
Objective The aim of this study was to investigate the cost-effectiveness of Helicobacter pylori (H. pylori) screening and eradication treatment in an asymptomatic population in China and to explore the most cost-effective screening protocol for H. pylori. Method We used TreeAge 2019 to construct Markov models to assess the direct healthcare costs and quality-adjusted life years (QALYs) and the cost per year of life saved (YoLS) of three therapies, i.e., annual, triennial and five-yearly H. pylori screening. Excess probabilities were derived from published high quality studies and Meta-analyses, and costs and utilities were derived from the Chinese Yearbook of Health Care Statistics and published studies. Incremental cost-effectiveness ratios (ICERs) were used to describe the results. The willingness-to-pay threshold was set at China’s Gross National Product per capita. Result In the asymptomatic population, the ICER per QALYs gained was US$1238.47 and US$1163.71 for every three and five years of screening compared to the annual screening group; the ICER per YoLS gained was US$3067.91 and US$1602.78, respectively. Conclusion Screening for H. pylori in asymptomatic populations in China and eradicating treatment for those who test positive is cost-effective. Increasing screening participation in asymptomatic populations is more effective than increasing the frequency of screening. From a national payer perspective, it is cost-effective to screen the general asymptomatic population in China for H. pylori and to eradicate those who test positive. Individuals need to choose a screening programme that they can afford according to their financial situation.
