ABSTRACT

Objective:

To conduct health economic evaluation of Chinese population-based screening and opportunistic testing strategies for the prevention of Helicobacter pylori ( H. pylori)-related diseases.

Methods:

The Markov models of H.pylori infection caused non-ulcer dyspepsia, peptic ulcer (PU) and gastric cancer were established. The cost and effects of the population-based screening, opportunistic testing, and non-intervention strategies in 100 000 population of our country were simulation calculated. Wilcoxon signed rank test was used for statistic analysis. Single factor sensitivity analysis was performed to analyze the impact of single parameter uncertainty on cost-effectiveness. Probability sensitivity was used to analyze the impact of common uncertainty of all parameters on cost-effectiveness.

Results:

Compared with opportunistic testing strategy and non-intervention strategy, the total cost of population-based screening strategy was reduced by 0.43 million yuan(-6.63 million yuan to 7.19 million yuan) and 4.45 million yuan(-8.60 million yuan to 27.93 million yuan), quality adjusted life years (QALY), life years and asmptomatic months were prolonged by 888.00 (479.86 to 1 574.10) and 3 032.78 (1 756.04 to 5 007.84), 651.82 (294.73 to 1 211.94) and 1 868.64 (1 045.88 to 3 148.34), 28 381.91 (19 109.54 to 43 736.72)and 102 537.13 (58 649.18 to 176 868.77) respectively, gastric cancer, deaths from gastric cancer, deaths from PU and deaths from various causes were reduced by 115 cases(52 cases to 232 cases) and 464 cases(266 cases to 803 cases), 74 cases(33 cases to 148 cases) and 260 cases(149 cases to 453 cases), 46 cases(25 cases to 72 cases) and 369 cases(210 cases to 710 cases), 80 cases(42 cases to 126 cases) and 501 cases(331 cases to 772 cases) respectively, and the differences were statistically significant ( Z=1.99, 10.54, 27.39, 27.39, 27.37, 27.39, 27.39, 27.39, 27.21, 27.28, 27.22, 27.28, 27.38, 27.39, 27.39 and 27.39, all P<0.05). Compared with the non-intervention strategy, the opportunistic testing strategy reduced the total cost by 3.89 million yuan(-2.79 million yuan to 18.18 million yuan), QALY, life years and asymptomatic months were prolonged by 1 764.77 (888.70 to 3 406.62), 1 044.16 (524.46 to 1 912.75) and 62 568.69 (30 054.07 to 129 892.76) respectively, gastric cancer, deaths from gastric cancer, deaths from PU and deaths from various causes were reduced by 311 cases(164 cases to 563 cases), 164 cases (87 cases to 301 cases), 325 cases(162 cases to 644 cases) and 399 cases(234 cases to 684 cases) respectively, and the differences were statistically significant ( Z=14.20, 27.39, 27.38, 27.39, 27.25, 27.25, 27.39 and 27.39, all P<0.01). The results of singlefactor sensitivity analysis showed that the uncertainty of any parameter did not affect the cost-effectiveness of three strategies. The results of probability sensitivity analysis indicated that the probability of cost-effectiveness advantage of the population-based screening strategy was 100% and the common uncertainty of all parameters had no effect on cost-effectiveness.

Conclusions:

For preventing H.pylori-related diseases, the population-based screening strategy has the lowest average cost and the best average effect. However, non-intervention strategy has the highest average cost and the worst average effect. Population-based screening strategy is worthy of promotion throughout China, and opportunistic testing strategy has a higher clinical practical value.
