Table 4 Factors associated with antimicrobial resistance

From: Trends in paediatric bloodstream infections at a South African referral hospital

Variable assessed Univariate analysis (p-value) Multivariate analysis (p-value) Odds ratio 95% CI
Length of stay prior to BSI onset <0.001 0.53 - -
Age category (infants) <0.001 0.003 1.92 1.2 – 3.1
Gender 0.8 0.92 - -
HIV status (positive) <0.001 <0.001 2.64 1.7 – 4.2
Year of BSI 0.4 0.19 - -
Place of BSI onset (hospital-acquired) <0.001 <0.001 3.68 2.7 – 5.1
Type of BSI pathogen     
- Gram negative <0.001 <0.001 1.99 1.4 – 2.9
Mono- vs poly-microbial BSI 0.18 0.84 - -
ICU vs general ward at BSI onset <0.001 0.06 - -
  1. BSI = bloodstream infection; ICU = intensive care unit; Hospital-acquired BSI = BC submitted > 72 hours after admission. To determine factors associated with antimicrobial resistance, binary logistic regression analyses were performed. A p-value below 0.05 was considered statistically significant.
