Monitoring results of maternal near miss in Henan Province,2016-2019

Objective To investigate the occurrence and risk factors of maternal near miss, and to provide theoretical evidence for reducing the incidence of maternal near miss by analyzing the surveillance data in 32 monitoring hospitals in Henan Province from 2016to 2019. Methods Retrospective analysis was used to analyze the surveillance data of maternal near miss collected through the maternal case report form in 32 monitoring hospitals in Henan Province from 2016 to 2019. The data were from the national maternal near miss surveillance system. The occurrence of complication, risk factors of maternal near miss were analyzed by logistic regression. Results There were 581 358 pregnant women monitored in 32 hospitals in Henan Province from 2016 to 2019. The incidence of pregnancy complications and maternal near miss was 47. 53%(276 325/581 358) and 0. 46%(2 648/581 358), respectively. There were 19 maternal deaths and the maternal mortality ratio(MMR) was 3. 27/100 000. The top five complications of pregnancy were anemia, combined with other diseases, diabetes mellitus, severe preeclampsia, and gestational hypertension. The top three causes of maternal near miss were anemia, combined with other diseases and uterine inertia. Logistic regression analysis showed that the number of parturition(including this delivery) being twice, and the number of prenatal care visits(excluding the current hospital visit) > 5were protective factors; age ≥35 years old, marital status being single/divorced/widowed/other, high school education level or below,parity(including current delivery)≥3, number of previous cesarean section≥1, and number of fetuses≥2 were the risk factors of maternal near miss. Conclusion Advanced age, marital status being single/divorced/widowed/other, lower education level, scarred uterus, multiple deliveries(≥3 times) and multiple pregnancies are the risk factors of maternal near miss in Henan Province.Scientific health education for high-risk pregnant women would be helpful to decrease the incidence of maternal near miss and maternal mortality rate.
