Sustained low incidence of central venous catheter-related infections in a Swedish county hospital following implementation of a hygiene program: a six year follow-up study
(English)Manuscript (preprint) (Other academic)
Background: There are limited data on the long term-effects of implementing a central venous catheter (CVC) program for prevention of CVC infections. The aims of this study were to evaluate the incidence of CVC colonization, catheter-related infections (CRI), catheter-related bloodstream infections (CRBSI), and their risk factors, over a six year period.
Methods: A continuous prospective study aiming to include all CVCs used at our hospital during the years 2004-2009, evaluating colonization, CRI, CRBSI and possible risk factors.
Results: 2772 CVCs were used during the study period. Data on culture results and catheterization time were available for 2045 CVCs used in 1674 patients. The incidences of colonization, CRI and CRBSI were 7.0, 2.2 and 0.6 per 1000 CVC-days. Analysis of quarterly incidences revealed one occasion with increasing infection rates. Catheterization time was a risk factor for CRI, but not for CRBSI. Other risk factors for CRI were hemodialysis, CVC use in the internal jugular vein compared to the subclavian vein. Hemodialysis was the only risk factor for CRBSI.
Conclusion: We found that that a CRI prevention program adhered to by the entire staff at a county hospital is successful in keeping CVC infections at a low rate over a long period of time.
