# Prevalence, pathogenic bacteria, and risk factors associated with pediatric sepsis among under five children in a rural district hospital in Rwanda

## TL;DR

This study examines pediatric sepsis in Rwanda, finding a high prevalence among under-five children, with specific risk factors and common bacterial causes identified.

## Contribution

The study provides new insights into sepsis prevalence, bacterial pathogens, and risk factors in a rural Rwandan hospital setting.

## Key findings

- 60.5% of enrolled children had positive blood cultures for sepsis.
- Coagulase-Negative Staphylococci and Staphylococcus aureus were the most common pathogens.
- Female gender and leukocytosis were significant risk factors for sepsis.

## Abstract

Pediatric sepsis poses a significant health challenge in Sub-Saharan Africa, with limited data on prevalence and pathogen profiles. This study determined the prevalence of pediatric sepsis, identified bacterial pathogens, and evaluated associated risk factors among children aged 1–59 months at Butaro Hospital, Rwanda.

A cross-sectional study was conducted from March 2022 to December 2022. The study included 114 children aged 1–59 months with suspected sepsis admitted to the pediatric ward at Butaro Hospital. Blood cultures were analyzed, and risk factors assessed using multiple logistic regression. Data were analyzed using Stata 17.

Of 114 enrolled children, 60.5% (n = 69) had positive blood cultures (95% CI: 51.2–69.1). Among these 69 children, the majority were females, 70.0% (n = 35) (95% CI: 53.7–81.3) and below 6 months 68.1% (n = 15) (95% CI: 45.3–84.7). Pathogenic bacteria identified were Coagulase-Negative Staphylococci (CNS), 59.4% (n = 41) and Staphylococcus aureus, 40.6% (n = 28). Female gender (AOR = 2.4, 95% CI: 1.0–5.4, p = 0.045) and leukocytosis (AOR = 6.0, 95% CI: 2.0–20.2, p = 0.003) were the risk factors for sepsis.

The study reveals a high prevalence of sepsis among children under-five, especially females and less than 6 months with female gender and diagnosis with leukocytosis being a significant risk factor. Diagnostic strategies should focus on WBC counts to better manage at-risk children. These single-center study results however may not be broadly representative due to regional and resource differences, but they offer valuable insights for improving pediatric care in similar low-resource settings.
