Abstract
Objective. To study placental abruption-associated maternal deaths out of all maternal deaths in Finland. Design. Register-based study. Setting. The Finnish Medical Birth Register (MBR), the Hospital Discharge Register (HDR), and the Cause-of-Death Register data during 1972–2005. Methods. The maternal deaths were identified by linking data from the MBR, the HDR, and the Cause-of-Death Register. The clinical data were collected from the case records and death certificates. Main outcome measures. Cause-specific maternal death with special reference to placental abruption. Results. During the study period, a total of 2,104,436 live births and 117 direct maternal deaths (caused by a disease or its management unique to the pregnancy) occurred in Finland. The direct maternal mortality ratio (MMR) was 5.6 per 100,000 live births. The two leading causes were thromboembolism (24.0%) and hemorrhage (22.3%) representing almost half of all maternal deaths. Altogether 7,735 placental abruptions were identified with three maternal deaths giving a case fatality rate of 0.4 per 1,000 cases. The MMR (38.8 per 100,000) was nearly seven times higher than the overall MMR (5.7 per 100,000) (p=0.010). Conclusion. The direct MMR in Finland is at the level generally seen in Western Europe. The main causes to maternal death are thromboembolism and obstetric hemorrhage. Deaths to placental abruption are rare, but still seven times higher than the overall MMR.
