通过对六盘水地区2015年至2020年孕产妇死亡评审进行调查，了解孕产妇死亡原因及相关影响因素，为降低孕产妇病死率提供参考依据。

对六盘水市妇幼监测报告系统收集的2015年至2020年六盘水地区孕产妇死亡个案资料及评审结果进行回顾性分析，采用统计学软件计算病死率及变化趋势，总结六盘水市孕产妇死亡变化趋势及死因构成情况。

2015年至2020年六盘水市报告显示孕产妇死亡51例，年平均病死率为20.45/10万；病死率每年呈下降趋势，年平均下降7.01%；死亡原因中前3位分别为产后出血13例（25.49%），羊水栓塞6例（11.76%），妊娠期高血压疾病6例（11.76%），可避免及创造条件可避免死亡36例（70.58%）。

2015年至2020年六盘水市孕产妇病死率呈逐年下降趋势，但孕产妇的死亡情况仍然需要重视，医疗机构需要加强产后出血、羊水栓塞及产科合并症的救治能力，同时提高孕产妇的健康宣传教育工作，进一步降低孕产妇的病死率。
