Analysis of the use of central venous catheters, mortality and catheter-related bloodstream infections in patients admitted to the ICU and after discharge to ward

Results 590 admitted patients: age 64.4 ± 15.4 years, 65% males, Apache II14.6 ± 9.2. 54.4% (321/590) required CVC. Apache II with CVC 19.2 ± 9.4 vs 9.1 ± 5 without CVC (p < 0.001). One CVC was inserted in 231 (72%), 2 in 72 (22.4%), 3 in 14 (4.4%), 4 in 2 (0.6%) and 5 in another 2 (0.6%). A total of 435 CVCs were inserted: 40% subclavian, 31.7% jugular, 26.9% femoral and 1.4% peripherally inserted central catheters.The main reason for CVCs was: sedation 68.8% (221), catecholamines 65.1% (209), either 83% (266) or both 51.1% (164); other causes: insulin infusion 15.9% (51), parenteral feeding 12.8% (41), continuous renal replacement therapy 7.5% (24), other 6.5% (21).The total CVC days in the ICU was 2545; 1 CRBSI episode was diagnosed (CRBSI incidence density 0.4 episodes/1000 catheter days). The total number of days of stay in the ICU was 2805.95 days (incidence density 0.36 episodes/1000 income days). CVC utilization ratio: 0.91.For patients requiring CVC, 43% (116/270) were discharged to ward with CVC. In ward, CRBSI incidence density was 0.29 episodes/1000 catheter days in hospital after ICU (one patient in 3476 days). We could not specify the number of days with CVC after discharge from ICU. Mortality analysis showed: 1) In ICU: patients with CVC 15.9% (51/321) vs without CVC 1.5% (4/269), p < 0.001; OR 12.5 (95% CI 4.535.1); (Apache II 28.3 ± 9.5 vs 20.5 ± 18.4, p = 0.148 NS). 2) After discharge from ICU: patients with CVC 8.6% (10/116) vs without CVC 2.6% (11/419); p = 0.003 (OR 3.5, 95% CI 1.4-8.5); Apache II 16.87 ± 84 vs 12.23 ± 7.5 (p < 0.001).
