Abstract
BACKGROUND: The association between IVC filter presence and subsequent bloodstream infection (BSI) is unknown. We hypothesized among patients with a new diagnosis of venous thromboembolism (VTE), incidence of BSI after one year would be higher in patients who had presence of an IVC filter.
METHODS: We performed a retrospective cohort study of patients with newly diagnosed VTE but no IVC filter (N= 4053) and patients with IVC filter (N=635) admitted to a metropolitan hospital system from 2006 - 2009 comparing incidence of BSI within one year of inclusion. Multivariable regression modelling was used to evaluate the association of IVC filter placement with BSI one year after placement.
RESULTS: Patients with an IVC filter placed were more likely to be older with higher Charlson co-morbidity score (median 4 vs. 1; p < 0.001). The incidence of BSI was not different between the group with IVC filter and the group without (10.7% vs. 8.8%; p = 0.12). There was no association with IVC filter placement and BSI before or after multivariable adjustment.
CONCLUSIONS: In patients newly diagnosed with VTE, we found no association between IVC filter placement and increased incidence of BSI after one year.
