The predictors of catheter-related bloodstream infections in patients undergoing hemodialysis: A single center experience.
Abstract
BACKGROUND\nHere we aimed to investigate the predictors of catheter-related bloodstream infections (CRBSI) in patients with acute kidney injury or chronic kidney disease who required renal replacement therapy through a non-tunneled hemodialysis catheter.\n\n\nMETHODS\nA total of 111 patients who received non-tunneled hemodialysis catheters were retrospectively evaluated. Patients were divided into two groups; those who developed CRBSI and those who did not. Patient s demographic data, laboratory results at admission, information regarding catheter infections, and culture results were obtained from electronic medical records.\n\n\nRESULTS\nThe mean age of the patients was 64\u2009±\u200916\u2009years, and 51 of them were male. CRBSI occurred in 14 patients (12.6%). Admission serum albumin level (OR: 0.119, 95% CI: 0.019-0.756, p\u2009=\u20090.024), admission mean platelet volume (OR: 2.207, 95% CI: 1.188-4.100, p\u2009=\u20090.012) and catheter duration (OR: 1.580, 95% CI: 1.210-2.064, p\u2009=\u20090.001) were independent predictors for the CRBSI development. ROC curve analysis demonstrated that a catheter duration of 22 days was predictive for presence of CRBSI (78% sensitivity, 76% specificity, AUC: 0.825, 95% CI: 0.724-0.925, p\u2009<\u20090.001).\n\n\nCONCLUSIONS\nProlonged catheter duration, low serum albumin, and high mean platelet volume independently predict the development of CRBSI in patients undergoing hemodialysis for acute kidney injury or chronic kidney disease.
