Removal of totally implanted venous access ports for suspected infection in the intensive care unit: a multicenter observational study

Background

While no data support this practice, international guidelines recommend the removal of totally implanted venous access ports (TIVAPs) in patients with suspicion of TIVAP-related bloodstream infection admitted in the intensive care unit (ICU) for a life-threatening sepsis

Methods

During this multicenter, retrospective and observational study, we included all patients admitted in five ICU for a life-threatening sepsis in whom a TIVAP was removed between January 2012 and December 2014. We aimed (1) at determining the proportion of confirmed TIVAP-related infections and (2) at assessing short- and long-term survival of patients with and without TIVAP-related infections

Results

One hundred and fifty-one patients (58 ± 14 years, 62% males) were included between 2012 and 2014. TIVAP-related infections were confirmed in 68 patients (45%). Demographic characteristics were similar between patients with and without TIVAP-related infections. SOFA score on admission per point increase [odd ratio (OR), 0.86 interval confidence (IC) 95% (0.8–0.9), p  < 0.01] and local signs of infection [OR 4.0, IC 95% (1.1–15.6), p  = 0.04] were significantly associated with TIVAP-related infection. Patients with TIVAP-related infection had lower ICU and 6-month mortality as compared to their counterparts (9 vs. 40%, respectively, p  < 0.01; and 50 vs. 66%, respectively, p  = 0.04). TIVAP-related infection was significantly associated with ICU survival [OR 0.2, IC 95% (0.05–0.5), p  < 0.01]

Conclusions

TIVAP-related infection was confirmed in nearly one out of two cases of life-threatening sepsis in patients in whom it has been removed. TIVAP-related infection was associated with a good prognosis, as compared to patients with other causes of infection.
