Background: Infant mortality is important as a standard indicator for the development of health, educational and social health systems in each country. Considering the fact that in different studies of the country there are different statistics on the prevalence of infant mortality in the intensive care unit and the general statistics on the prevalence of mortality in neonates in the country are unclear and unclear, the aim of this study was systematic review and meta-analysis for determine the prevalence of mortality in infants admitted to the intensive care unit (ICU) of hospitals in Iran. Methods: A meta-analysis was performed for relevant articles in scientific databases including scientific information database (SID) and Magiran, ScienceDirect, Scopus, Medline (PubMed) and Google Scholar. Entrance criteria included cross-sectional studies between March 2000 to September 2018. The search process in these databases was performed using keywords: Neonatal, Intensive Care Unit, Mortality, and Iran. Non-relevant articles included review articles, interventions, cohorts and case-control studies, excluded from the study list. Heterogeneity of study was checked using I2 index and the possibility of publication bias by funnel plot and Egger test. Data were analyzed using the comprehensive meta-analysis software, version 3 (Biostat, Englewood, NJ, USA). Results: The overall prevalence of infant mortality in ICU hospitals was 21.8% (95% CI 14.4-31.6%), the highest prevalence of infant mortality in Isfahan was 64.4% percentage (95% CI 57.5-70.9%) and the lowest mortality rate in babies in Babol's intensive care unit with 5.1% (95% CI 3.8-6.7%). The results of the study showed that the prevalence of infant mortality was significantly reduced with increasing sample size (P<0.05). Also, with an increase in years of research, the frequency of infant mortality in the intensive care unit increases, which is also statistically significant respectively (P<0.05). Conclusion: Considering the high prevalence of infant mortality in ICU hospitals in Iran, health policy makers need to take effective measures to raise awareness of parents as well as effective measures to reduce infant mortality.
