[Analysis of maternal deaths in Shanghai from 1996 to 2015].

ABSTRACT

Objective: To analyze the trend of maternal mortality ratio (MMR) and cause of death in Shanghai from 1996 to 2015. Methods: To collect the material about the maternal death and the maternal death audit from 1996 to 2015, and to analyze the MMR, the cause of death and the result of the maternal death audit of Shanghai from 1996 to 2015 retrospectively. Results: (1) The change of MMR the MMR in Shanghai decreased from 28.84 per 100 000 live births in 1996 to 6.66 per 100 000 live births in 2015. (2) The characteristic of maternal death the proportion of Shanghai citizens was 27.4%(121/441) and the proportion of migrant women was 72.6%(320/441). The women with advanced maternal age was 8.2% (20/243) since 1996 to 2005, and increased to 16.7% (33/198) since 2006 to 2015. Maternal deaths during pregnancy increased from 27.6%(67/243) in the first 10 years (1996-2005) to 35.4%(70/198) in the recent 10 years (2006-2015) . The intrapartum maternal deaths was 6.2%(15/243) in the first 10 years and in the recent 10 years it was zero. The proportion of postpartum deaths in the first 10 years and in the recent 10 years were 66.3% (161/243) and 64.6%(128/198) respectively. (3) The cause of maternal death During the recent 10 years, indirect obstetric causes [63.1%(125/198)] was more than direct obstetric causes [36.9% (73/198) ] for the first time. The death causes changed significantly. Postpartum hemorrhage remained the leading cause of maternal deaths, but the specific mortality rate (SMR) of postpartum hemorrhage decreased significantly from 7.42 per 100 000 live births in the first 10 years to 1.51 per 100 000 live births in the recent 10 years. The maternal deaths because of heart disease and cerebrovascular disease rose to the second and the forth reasons. (4) Maternal death audit the avoidable maternal death ratio decreased from 3.66 per 100 000 live births in the first 10 years to 1.86 per 100 000 live births in the recent 10 years. Conclusions: During the past 20 years, the MMR of Shanghai decreased significantly and was close to the level of developed countries. In recent years, the causes of maternal death become more complicated. With the implementation of the second child policy, women with high risk factors increase, so government investment, policy support should be strengthened to optimize the management.
