[Neonatal healthcare associated-infections in the Maghreb. A systematic review and meta-analysis]

BACKGROUND

Healthcare-associated infections are a major source of morbidity and mortality in neonatology. Our aim was to describe the epidemiology of Healthcare-associated infections in neonatology (frequency, associated factors and prognosis).

METHODS

Articles were searched in the PubMed, Scopus and Web of Science databases. We included observational studies describing prevalence, incidence or mortality among new-born babies having developed infections more than 48hours after hospitalization. The pooled prevalence, incidence and mortality estimates were analysed using the random effects model. Publication bias was analysed using the funnel plot and Egger's test statistics. Data analysis was carried out using R Studio software v1.2.

RESULTS

Among the initially identified 137 studies, ten articles fulfilled the inclusion criteria and were included in the metanalysis. They mainly concerned Morocco, Tunisia and Algeria. Pooled incidence was 10% (95% CI [4%-18%]) and overall mortality was 49% (95% CI [33%-66%]). Heterogeneity between studies was significantly high, with rates of 98% and 90% respectively.

CONCLUSION

This review underlined a need to undertake more large-scale multicentric surveys and studies on monitoring systems and the attitudes and practices of relevant caregivers, the objective being to better understand the realities of healthcare-associated infections in Greater Maghreb neonatology units.
