Neonatal sepsis and its association with birth weight and gestational age among admitted neonates in Ethiopia: systematic review and meta-analysis.

backgroundNeonatal sepsis is an invasive infection, usually bacterial, and often occurring during the neonatal period (0-28 days). Neonatal sepsis causes a high burden of morbidity and mortality in developing countries like Ethiopia. There are fragmented, inconsistency, and no review has been conducted to report the magnitude and associated factors of neonatal sepsis in Ethiopia. Thus, this study aimed to assess the pooled prevalence of neonatal sepsis and its association with birth weight and gestational age among admitted neonates in Ethiopia.

methodsElectronic media searches like PubMed, CINHAL, EMBASE, Google Scholar, Web of Science, Cochrane library databases and African health science library were used. All original peer-reviewed papers which reported the prevalence of neonatal sepsis in Ethiopia were included in this study. Two reviewers independently extracted the data using a standardized data extraction format for eligibility and appraised their quality. Data were analyzed using Stata version 14 software. The pooled prevalence of neonatal sepsis was estimated with the random-effect model. Heterogeneity between studies was assessed by I

resultA total of 952 research papers reviewed, of which, eight studies were finally included in this systematic review and meta-analysis. The random effect pooled prevalence of neonatal sepsis in Ethiopia was 49.98% (CI: 36.06, 63.90). In subgroup analysis, the pooled estimated neonatal sepsis among cross-sectional studies was 53.15% while the cohort was 40.56%. Newborns with a birth weight of less than 2.5 kg were 1.42 times more likely to develop neonatal sepsis infection compared to normal babies. The odds ratios of preterm babies were 3.36 to develop neonatal sepsis compared to term infants.

conclusionThe pooled prevalence of neonatal sepsis in Ethiopia was high. Thus, health care providers should adhere to aseptic precautions while performing procedures, especially in preterm and low birth weight infants were recommended.
