S. aureus bacteremia is largely community-acquired in children in New Zealand and is more common in Pacific Island and Maori populations. Although there is a low associated mortality, a significant number are potentially preventable cases secondary to intravenous catheters.

Staphylococcus aureus bacteraemia is more likely to occur in certain ethnic groups, while mortality is associated with other identifiable risk factors and continues to be high. Intravenous catheters remain the most common and most preventable cause of SAB.

Textile permeability in general shows a high variance. The present work describes a method to model textile variability at the mesoscopic scale based on a generalised textile model. Inhomogeneities were introduced into the textile structure by randomly moving the tow paths at the cross-overs according to a given normal distribution. The effects of various factors on the evaluated permeability variation were explored and demonstrated, using non-crimp fabric and plain weave models. Fabric architecture was shown to be important in that it imposed a limit to the degree of variation of the tows. A linear relationship can be deduced for the relative variation of permeability as a function of the relative variation of fibre volume fraction, which links the predicted and measured values. When utilising predicted mesoscopic permeability values in macroscopic analyses, the domain size of the mesoscale model has to be related to the element size of the macroscopic analyses.
