目的运用Robson分类法对剖宫产进行统计分类,了解该院近五年剖宫产率变化情况。方法收集2011-2015年该院分娩的50363名产妇信息,依据5个产科特征分为10组,分别计算每组剖宫产率。结果五年平均剖宫产率为46.14%,五年剖宫产率呈下降趋势(Z=15.06,P<0.01)。各组剖宫产率经Cochran-Armitage趋势检验,除G4(Z=1.32,P=0.09)、G9(Z=0.60,P=0.27)和G10(Z=-0.32,P=0.37)组外,其余七组均呈下降趋势(Z=15.16,5.27,7.70,15.21,3.04,2.04,4.07;P<0.01)。结论该院剖宫产率与同类型医院相持平并呈现下降趋势。
Objective To classify cesarean section by Robson classification and learn about the change of cesarean section rate in the past five years. Methods The data of 50363 maternal mothers in our hospital from 2011 to 2015 were collected and divided into 10 groups based on 5 obstetric traits. Cesarean section rates were calculated for each group. Results The average cesarean section rate in five years was 46.14%. The five-year cesarean section rate showed a decreasing trend (Z = 15.06, P <0.01). Cesarean section rate in each group was tested by Cochran-Armitage trend test. Except G4 (Z = 1.32, P = 0.09), G9 (Z = 0.60, P = 0.27) and G10 (Z = -0.32, P = 0.37) The remaining seven groups showed a downward trend (Z = 15.16,5.27,7.70,15.21,3.04,2.04,4.07; P <0.01). Conclusion The hospital cesarean section rate and the same type of hospital flat and showed a downward trend.
