Epidemiological analysis of maternal death in Beijing from 1995 to 2010 / 中华预防医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analysis the trend of maternal death time and explore the impact of the variety of death causes and birth place to maternal death time.</p><p><b>METHODS</b>According to the data provided by Beijing Maternal and Children Health Hospital, the 372 death cases of pregnant and lying-in women from 1995 to 2010, a retrospective study was performed to analyze the death causes, maternal death time and the influencing factors.</p><p><b>RESULTS</b>The MMR declined from 27.9 per 100 000 live births from 1995 to 2000 to 14.8 per 100 000 live births from 2006 to 2010, with a decline of 46.9%. Among the maternal death within 24 hours of delivery, 79.7% (106/133) died of obstetric hemorrhage, hypertensive disorder complicating pregnancy and amniotic fluid embolism. It took up 47.8% (64/134) from 1995 to 2000, reduced to 37.5% (45/120) from 2006 to 2010. At the same time, the maternal mortality ratio within 24 hours reduced from 40.2%(54/134) to 28.3% (34/120), the variation of death time was consistent with the causes of maternal mortality (χ² = 59.109, P < 0.05). Indirect obstetric causes increased significantly from 2006 to 2010, 53.2% (33/62) of pregnant women with heart disease, cerebrovascular disease and pulmonary embolism died in prenatal or more than 120 hours postnatal. Among the maternal death delved in hospital, 29.0% (29/100) died within 24 hours, 52 cases delved at home or in private clinics, 43 cases (82.6%) died within 24 h postnatal. There were significant differences between birth place and death time (χ² = 24.500, P < 0.05).</p><p><b>CONCLUSION</b>Maternal death time changed from 24 hours of delivery to prenatal or postnatal a long time. The maternal mortality causes and hospital delivery is an important factor affecting maternal time.</p>
