Background and Aim: Thrombocytopenia is one of the most common hematological disorders in infants, and more than one-third of affected infants are admitted to the neonatal intensive care unit, so the aim of this systematic review and meta-analysis is to determine the prevalence of thrombocytopenia in infants admitted to intensive care unit.
Materials and Methods:This study is a systematic review and meta-analysis by examining Scientific Information Database (SID), Medline (PubMed), ScienceDirect and Google Scholar until August 2023. Extracted data were analyzed by Comprehensive meta-analysis software (version 2).
Results:In a review of 8 studies with a sample size of 4507 children, based on a meta-analysis, the prevalence of thrombocytopenia in infants hospitalized in intensive care unit was reported as 14.8 (95% CI: 8.8-23.9), Also, examining publication bias in studies through the Egger test indicates the absence of publication bias in studies (p: 0.974). . Conclusion: The results of the present study show that the prevalence of thrombocytopenia in infants hospitalized in intensive care unit is high and requires the special attention of health policymakers, hospital officials, and the necessary educational measures for pregnant mothers.
