Maternal Near-Miss Definitions and Indicators

Terminology Definitions
Near-miss indicators
Maternal near miss (MNM) A woman who nearly died but survived a complication that occurred during pregnancy, childbirth or within 42 days of termination of pregnancy
MNM ratio (MNMR) The number of maternal near-miss cases per 1000 live births
Maternal mortality ratio (MMR) The number of maternal deaths per 100,000 live births
Severe maternal outcome (SMO) The sum of maternal near misses and maternal deaths
Severe maternal outcome ratio (SMOR) The number of women with SMO per 1000 live births (LB). This indicator gives an estimate of the amount of care and resources that would be needed in an area or facility
Maternal near-miss mortality ratio (MNM: 1 MD) The ratio between maternal near miss and maternal deaths. Higher ratios show better care
Mortality index The number of maternal deaths divided by the number of women with SMO. The lower the index, the fewer women with life-threatening complications die (better quality of care) whereas the higher the index, the more women with life-threatening complications die (low quality of care)
Hospital access indicators
SMO12 Women presenting the organ dysfunction or maternal death (SMO) within 12 hours of hospital stay from admission
SMO12 mortality index The number of women with SMO12 divided by the number of all SMO cases expressed as a percentage
Intrahospital access indicators
SMO after 12 hrs of hospital stay 12 Women experienced SMO after 12 hours of hospital stay
SMO after 12 hrs mortality index The number of women with SMO after 12 hours of hospital stay divided by the number of all SMO cases expressed as a percentage
Process indicators
Prevention of postpartum haemorrhage The number of women who received a single dose of oxytocin divided by the number of all women giving birth
Treatment of severe postpartum haemorrhage The number of women with severe PPH who received therapeutic oxytocin divided by the number of all women with postpartum haemorrhage.
Treatment sepsis The number of women with sepsis who received IV antibiotics divided by the number of all women with sepsis
