The global prevalence of maternal near miss: a systematic review and meta-analysis

Background: Improving the maternal health is one of the world’s most challenging problems. Despite significant movements over the past decades, maternal health has been still considered as a central goal for sustainable development. Maternal near miss (MNM) cases experience long-term physical and psychological effects. To present a clear portrait of the current situation, we performed a systematic review and meta-analysis with the purpose to assess the worldwide prevalence of MNM. Methods: We conducted a systematic review on PubMed, Scopus and Web of Science electronic databases to find published papers in English, before March 2019 and regardless of the type of study. We, then, assessed the prevalence of MNM according to the World Health Organization(WHO) criteria. Finally, 49 papers were included in the study. Random effects meta-analysis was used to pool the available prevalence. The quality of studies was also evaluated. Results: The weighted pooled worldwide prevalence of MNM, was 18.67/1000 (95% CI: 16.28-21.06). Heterogeneity was explored using subgroup analyses based on the continent and the country. We used meta-regression of MNM on MD which resulted in adjusted R-squared as78.88%. Conclusion: The prevalence of MNM was considerable. Low- and middle-income countries should develop systematic approaches to improve quality of care in the facilities and to reducethe risk of MNM events, with the hope to women’s health.
