作者研究了一种简易方法筛检HB_sA_g阳性的孕妇,并用决策分析和成本-效益分析与其它乙肝控制策略作了比较评价。当乙肝疫苗成本高时,这一方法成本-效益较好,但随着疫苗成本的持续降低,在乙肝群体免疫接种策略中其作用则是鉴别出生后应马上注射乙肝疫苗的婴儿。
The authors studied a simple method for screening HBsA_g-positive pregnant women and compared them with other hepatitis B control strategies using decision analysis and cost-benefit analysis. While the cost of hepatitis B vaccine is high, the cost-effectiveness of this approach is good, but as vaccine costs continue to decline, its role in hepatitis B vaccine immunization is to identify infants who should be given hepatitis B vaccine immediately after birth.
