Femoral Venous Catheterization Is a Major Risk Factor for Central Venous Catheter-Related Bloodstream Infection

BACKGROUND: Bloodstream infection is a major complication associated with central venous catheters (CVCs). However, there have been few studies of the risk factors for catheter-related bloodstream infection in patients who undergo colorectal surgery (CRS). PURPOSE: To disclose the risk factors for catheter-related bloodstream infection in CRS. METHODS: Catheter-related bloodstream infection was evaluated retrospectively from a database of patients who had undergone CRS. RESULTS: Three hundred-fifty patients received 423 CVCs for a total of 7,760 catheter days. Thirty-nine cases of catheter-related bloodstream infection (5.03 per 1,000 catheter days) were diagnosed. There were no significant differences in background between patients with or without catheter-related bloodstream infection, with the exception of the term of catheter insertion (24.6 +/- 7.0 days vs.17.7 +/- 0.6 days, P = .0151). However, univariate analysis using factors of sex, age, insertion difficulty, length of the inserted catheter, term of catheter insertion, administration of chemotherapy, administration of total parenteral nutrition (TPN), kind of disinfectant, degree of surgical insult, and type of catheter revealed that use of a femoral venous catheter was an independent risk factor for catheter-related bloodstream infection (odds ratio [OR] = 3.175; 95% confidence interval [CI], 1.103-9.139; P = .0322). CONCLUSIONS: Use of femoral venous catheters is a major risk factor for catheter-related bloodstream infection in CRS.
