The figures can be represented by a rate per 1000 live births, per 1000 total births, per 1000 maternities - ie mothers delivering - or per 1000 pregnancies, which includes abortions and ectopic pregnancies. American data is often expressed as a rate per 100,000 of each of these classes.
- maternal mortality rate, calculated from all maternal mortality Directly or Indirectly due to pregnancy identified by this Enquiry, for 2006-08 was 11.39 (95% CI 10.09-12.86) per 100 000 maternities compared with the 13.95 (95% CI 12.45-15.64) per 100 000 maternities reported for the previous triennium, 2003-05
- main reason for the decline in deaths from Direct causes is a significant reduction in deaths from thromboembolism and, to a lesser extent, from other Direct conditions such as haemorrhage. The prevention and management of these two life-threatening
- case fatality rate from ectopic pregnancy has almost halved from an estimated 31.2 (95% CI 16.8-57.9) per 100 000 estimated ectopic pregnancies for 2003-05 to 16.9 (95% CI 7.6-37.6) for this triennium (P = 0.23).
