We investigated perceptions of the causes of maternal mortality by women attending referral hospitals in Nigeria. Focus group discussions were conducted with various categories of women. Our results showed that women were aware of the medical causes of mortality, although a few listed divine reasons. Delays in reaching hospitals or after women arrive in hospitals featured prominently as lead causes mentioned by women. Listening to women as end-users is an important approach to identify points of remediation in the provision of maternal health care. This should be taken into cognizance when policymakers or international agencies plan the prevention of maternal deaths in developing countries.
