Culture Positivity of CVCs Used for TPN: Investigation of an Association with Catheter-Related Infection and Comparison of Causative Organisms between ICU and Non-ICU CVCs

Table 1

Comparison of CRBSI versus culture positive CVCs (episodes per year).

VariableMean annual number of episodesStandard error

CVCs that developed CRBSI17.51.98

CVCs that became culture positive54.252.15

Difference−36.751.83

𝑃 < 0 . 0 1 . Legend: The difference between CP and CRBSI episodes of 36.75 (SE 1.83) over the 12 years of observation is statistically significant, suggesting a consistent pattern of culture positive CVCs that resulted in development of CRBSI.
