Maternal death is defined by the World Health Organisation (2) as:
‘Deaths of women while pregnant or within 42 days of delivery, miscarriage or termination of pregnancy, from any cause related to or aggravated by the pregnancy or its management, but not from accidental or incidental causes.’
Direct – deaths resulting from obstetric complications of the pregnant state (pregnancy, labour and puerperium), from interventions, omissions, incorrect treatment or from a chain of events resulting from any of the above.
Indirect – deaths resulting from previous existing disease or disease that developed during pregnancy and which was not due to direct obstetrics causes, but which was aggravated by the physiological effects of pregnancy.
Late – Deaths occurring between 42 days and one year after termination of pregnancy, miscarriage or delivery that are due to direct or indirect maternal causes.
Coincidental – deaths from unrelated causes which happen to occur in pregnancy or the puerperium.
All deaths occurring during pregnancy and up to one year following the end of pregnancy must be reported to MBRRACE, irrespective of the nature of the pregnancy or the cause/circumstances of the death. These deaths may occur within Maternity services, in other departments within the hospital, or in the community.
