Maternal mortality in the main referral hospital in The Gambia, west Africa.

A retrospective analysis of 78 maternal deaths was performed during 1991-1992 to estimate maternal mortality at the maternity unit of the main tertiary level hospital in The Gambia. The non-abortion maternal mortality ratio (MMR) was 736 per 100 000 live births. Among the direct causes, haemorrhage caused most deaths (24%), followed by hypertensive disorders in pregnancy (HDP) (21%). Sepsis was the main cause of death in 15%. Anaemia led among the indirect causes of death (8%) and was a co-factor in 41% of all deaths. Substandard care factors other than medical causes were determined involving health care facilities, staff, drugs and equipment, and patient-related factors. Well known risk factors of low age (< or = 19 years) and nulliparity were highly represented in the maternal death group, and delivery by Caesarean section occurred more than threefold compared to the overall Caesarean section rate. Taking haemorrhage as an example, it is demonstrated that the way diagnoses are grouped significantly affects the statistical elaboration of maternal deaths.
