我军甲肝疫苗接种的成本-效果分析

目的 筛选出部队人群疫苗预防甲肝的最佳策略，为部队控制甲肝流行提供科学决策的依据。方法 运用成本-效果分析法和决策学方法。结果 从接种方案的成本-效果比（CER）来看，对部队干部人群实施先筛选再接种，其CER为-1231.27，直接接种CER为-269.84，新兵先筛选再接种，其CER为-762.56,直接接种CER为-32.10。经灵敏度分析发现，决策结果稳定，不随参数取值的变化而改变。结论 当前条件下，部队甲肝疫苗接种优选对象为干部人九，并首选先筛选再接种方案，由于新兵接种甲肝疫苗也产生正效益，所以对新兵也应考虑接种。

Cost-effectiveness analysis of hepatitis A vaccination strategy among Chinese PLA

AIM　To screen the most cost effective strategy for vaccination against hepatitis A in the armies. METHODS　Cost-effectiveness and decision tree analysis were adopted for decision making of vaccination strategies against HA in armies. RESULTS　Cost-effectiveness ratio (CER) of ‘screen and vaccination’ (-1231.27) was lower than that of ‘direct vaccination’ (-269.84) for the officers. As far as the recruits were concerned, the former (-762.56) was lower than the latter (-32.10) too. Sensitivity analysis demonstrated that the result of decision did not change with the variation of the input data. CONCLUSION　Officers should be considered first for vaccination and the screening-vaccination strategy is most cost-effective for them. The recruits should also be considered for the positive benefit of vaccination.
