The Maternal Near Miss Incidence Ratio with WHO Approach in Iran: A Systematic Review and Meta‑Analysis

Maternal near miss (MNM) is one of the important criteria for checking the quality of care in maternal health. This systematic review and meta‑analysis study was conducted in 2017 to evaluate the incidence ratio of MNM using the World Health Organization approach in Iran. This study was designed based on Preferred Reporting Items for Systematic Reviews and Meta‑Analyses (PRISMA) checklist for systematic reviews, and Web of Science and PubMed databases were searched systematically, which, respectively, yielded 171 and 137 papers published before June 9, 2017. To include papers written in Persian by Iranian scholars, Google Scholar database was searched and 542 papers were retrieved. Finally, 12 papers which had covered the topic more appropriately were included in the study. Random‑effects meta‑analysis was used to pool the incidence ratio. Heterogeneity was explored using formal tests and subgroup analyses, then the study quality was also explored. The pooling of overall potentially life‑threatening conditions ratio was I2 (97.60%, p < 0.001, ratio = 2.50/1000 live births [LBs] [95% CI: 2.00‑3.00]), which is divided into two indicators: severe complication ratio (2.40/1000 LBs) and critical intervention ratio (2.54/1000 LBs). The pooling of overall life‑threatening conditions ratio was I2 (95.10%, p < 0.001, ratio = 0.86/1000 LBs [95% CI: 0.64‑1.07]). The incidence ratio of MNM needs more attention in Iran. Therefore, it is necessary to identify the factors related to MNM and then implement suitable strategies to reduce the risk factors of the maternal morbidity and improve the quality of maternal care in facilities.
