We conducted a study in which 5,754 pregnant women who delivered at the Grace Maternity Hospital in Halifax were screened for HBsAg. There were five who were found to be seropositive for the first time (a screening yield for seropositivity of 8.7/10,000). Overall six were seropositive for a prevalence rate of 10.4/10,000. These rates are above the 6.0/10,000 level at which routine prenatal screening is considered to be cost-effective. Screening based upon risk factors would have identified only two of the five women who were found for the first time to be HBsAg seropositive. Based upon the results of this study, we recommend that routine screening for HBsAg be performed on all prenatal women in Nova Scotia.
我们开展了一项研究，对在哈利法克斯的格蕾丝妇产医院分娩的5754名孕妇进行了乙肝表面抗原（HBsAg）筛查。有5名孕妇首次被检测为血清学阳性（血清学阳性筛查率为8.7/10000）。总体上有6名孕妇血清学阳性，患病率为10.4/10000。这些比率高于被认为具有成本效益的常规产前筛查水平6.0/10000。基于风险因素的筛查仅能识别出首次被检测为HBsAg血清学阳性的5名孕妇中的2名。基于这项研究的结果，我们建议对新斯科舍省的所有产前妇女进行HBsAg常规筛查。
