Vascular access for renal replacement therapy among 459 critically ill patients: a pragmatic analysis of the randomized AKIKI trial

Annals of Intensive Care

Table 6 Possible catheter-related complications according to insertion site (all catheters)

	Femoral (n = 319 catheters)	Jugular (n = 256 catheters)	Sub-clavian (n = 23 catheters)	p values (femoral vs jugular)
Infectious complications
Catheter-related bloodstream infections
Number^a	6 (1.9%)	7 (2.7%)	0	0.58
Incidence rate (%)^b	2.2%	3.2%		–
Incidence density (‰ catheter-days)^c	3.1‰	4.4‰		–
Bloodstream infections without cause^a	5 (1.6%)	1 (0.4%)	0	0.23
Mechanical complications^a
Pneumothorax	0	0	0	1.00
Hemothorax	0	0	0	1.00
Gas embolism	1 (0.3%)	0	0	1.00
Fistula	1 (0.3%)	0	0	1.00
Bleeding requiring transfusion or hemostatic procedure^a	2 (0.6%)	2 (0.8%)	0	1.00
Thrombotic complications^a
Symptomatic deep venous thrombosis^a	2 (0.6%)	3 (1.2%)	0	0.66

All complications above are «catheter related» except «bloodstream infections without cause»
P values: Fisher’s exact test for count data. No p value calculated for incidence rate and incidence density because the two samples were not independent. Patients could have a femoral and jugular catheter
^aAll percentages are expressed as number of events per number of catheters except for incidence rate and incidence density
^bIncidence rate: number of patients contracting an infection per number of patients at risk (272 patients under femoral catheter and 221 patients under jugular catheter)
^cIncidence density: number of infection per 1000 catheter-days
