Central Lines Infection Incidence and Risk Factors in an Intensive Care Unit, a Retrospective Cohort Study

Background: The central lines are fundamental for the intra-hospital management of many patients, especially critical ones, but the complications associated with those devices like infection could increase the morbidity and mortality of patients.In this study we figure the factors associated with infection in a private hospital. Material and Methods:We conduct a retrospective study including 710 patients with central venous catheters in the period from 2014 to 2017.General data and variables like age, diagnosis, days of catheter use, site of insertion, number of punction and others were registered and analyzed.Results: From the total analyzed patients only 19 present central venous line associated infection (.026%), from the analyzed factors only the number of catheter lumen and the days with catheter were significantly associated with infection, the most frequent microorganism was the Staphylococcus epidemidis as mentioned in the literature.Factors like number of punction during installation, site of placement, service of installation or diagnosis did not show significant results.Conclusion: The incidence of infection in the hospital was very low compared with worldwide literature, and the risk factors associated with this are similar to previous described including multiple lumens and days with catheter, some of them have been described but not significant in our population, maybe secondary to sample size or hospital bias.A prospective study would be useful for morespecific results.
