Abstract
ABSTRACTObjectiveThere is an economic evaluation on the family‐based Helicobacter pylori screen‐and‐treat strategy (FBHS) in China. This study aimed to compare the cost‐effectiveness of the FBHS with the traditional H. pylori screen‐and‐treat strategy (TBHS).Materials and MethodsA seven‐state microsimulation model, including H. pylori infection and gastric cancer states, was constructed on the basis of the target family samples from 29 provinces in China. Taking a lifetime horizon from a healthcare system perspective, the long‐term costs and health outcomes of the FBHS and TBHS screening strategies were simulated separately, and economic evaluations were performed. The model parameters were primarily derived from real‐world data, published literature, and expert opinions. The primary outcome was the incremental cost‐effectiveness ratio (ICER) expressed as cost/quality‐adjusted life‐year (QALY) gained. One‐way sensitivity analysis, probabilistic sensitivity analysis, and scenario analysis were performed to assess the uncertainty of the results.ResultsThe base‐case analysis revealed that the average costs for FBHS and TBHS were 563.67 CNY and 574.08 CNY, respectively, with corresponding average QALYs of 14.83 and 14.79. The ICER for the comparison between the two strategies was −214.07, indicating that FBHS was an absolutely dominant strategy with better cost‐effectiveness. The results of both one‐way sensitivity analysis and probabilistic sensitivity analysis were robust. When taking into account the added benefit of the higher H. pylori eradication rate in FBHS, the average costs were further reduced, and the average QALYs were increased, solidifying its position as an unequivocally dominant strategy.ConclusionThe FBHS is an absolutely dominant and cost‐effective strategy that enables an optimized allocation of screening resources. Decision‐makers should prioritize FBHS when developing H. pylori prevention and control strategies.
