BackgroundAnalysis of severe maternal morbidity (maternal near misses) provides information on the quality of care. We assessed the prevalence/incidence of maternal near miss, maternal mortality and case fatality ratio through systematic review of studies on severe maternal morbidity in sub-Saharan Africa.MethodsWe examined studies that reported prevalence/incidence of severe maternal morbidity (maternal near misses) during pregnancy, childbirth and postpartum period between 1996 and 2010. We evaluated the quality of studies (objectives, study design, population studied, setting and context, definition of severe acute obstetric morbidity and data collection instruments). We extracted data, using a pre-defined protocol and criteria, and estimated the prevalence or incidence of maternal near miss. The case-fatality ratios for reported maternal complications were estimated.ResultsWe identified 12 studies: six were cross-sectional, five were prospective and one was a retrospective review of medical records. There was variation in the setting: while some studies were health facility-based (at the national referral hospital, regional hospital or various district hospitals), others were community-based studies. The sample size varied from 557 women to 23,026. Different definitions and terminologies for maternal near miss included acute obstetric complications, severe life threatening obstetric complications and severe obstetric complications. The incidence/prevalence ratio and case-fatality ratio for maternal near misses ranged from 1.1%-10.1% and 3.1%-37.4% respectively. Ruptured uterus, sepsis, obstructed labor and hemorrhage were the commonest morbidities that were analyzed. The incidence/prevalence ratio of hemorrhage ranged from 0.06% to 3.05%, while the case fatality ratio for hemorrhage ranged from 2.8% to 27.3%. The prevalence/incidence ratio for sepsis ranged from 0.03% to 0.7%, while the case fatality ratio ranged from 0.0% to 72.7%.ConclusionThe incidence/prevalence ratio and case fatality ratio of maternal near misses are very high in studies from sub-Saharan Africa. Large differences exist between countries on the prevalence/incidence of maternal near misses. This could be due to different contexts/settings, variation in the criteria used to define the maternal near misses morbidity, or rigor used carrying out the study. Future research on maternal near misses should adopt the WHO recommendation on classification of maternal morbidity and mortality.
