It has been shown that an intensive system of preterm birth prevention using home uterine activity monitoring can decrease the number of early births. Such a system was employed in 130 public assistance (Medicaid) patients who were at high risk for preterm birth. A retrospective review of the pregnancy outcome in these subjects was conducted and their data exposed to a model for projected patient care cost. The incidence of preterm labor in the at-risk group was 46%, with an average prolongation of pregnancy of 4.9 weeks. The occurrence of preterm delivery for failed tocolysis or advanced cervical dilatation was less than 10%. Based on a cost-analysis model that considered newborn charges and monitoring expenses, nearly [corrected] $3 million (an average of $21,813 [corrected] per patient) was saved using this system.
研究表明，采用家庭子宫活动监测的强化早产预防系统可减少早产数量。该系统应用于130名早产高危的公共援助（医疗补助）患者。对这些受试者的妊娠结局进行了回顾性分析，并将其数据应用于预计患者护理成本模型。高危组早产发生率为46%，平均妊娠延长4.9周。因宫缩抑制剂治疗失败或宫颈扩张进展导致的早产发生率低于10%。基于考虑新生儿费用和监测费用的成本分析模型，使用该系统节省了近300万美元（平均每位患者21,813美元）。
