Table 4 Primary and Secondary outcomes per catheter

Primary outcome
Phlebitis per catheter	Number of catheters/total PIVCs	535/7118
	Proportion, % (95% CI)	7.5 (6.9–8.2)
	Time to phlebitis^a, median (IQR), hours	36.3 (17.8–58.6)
	Incidence rate per 100 intravenous catheter-days (95% CI)	3.3 (3.0–3.6)
Secondary outcomes
CRBSI	Number of catheters/total PIVCs	3/7025
	Proportion, % (95% CI)	0.04 (0.02–0.13)
	Time to removal^b, median (IQR), hours	481.5 (12.8–558.3)
	Incidence rate per 1000 intravenous catheter-days (95% CI)	0.18 (0–0.39)
Catheter failure	Number of catheters/total PIVCs	1492/7118
	Proportion, % (95% CI)	21.0 (20.0–21.9)
	Time to removal^b, median (IQR), hours	48.3 (23.3–81.9)
	Incidence rate per 100 intravenous catheter-days (95% CI)	9.1 (8.7–10.0)

CI confidence interval, CRBSI catheter-related blood stream infection, ICU intensive care unit, IQR interquartile range, PIVC peripheral intravenous catheter
^aTime to phlebitis means the duration between insertion of the catheter and detection of phlebitis
^bTime to removal means the duration between insertion and removal of the catheter
