This meta-analysis suggests that age, diabetes, kidney disease, history of catheter-associated infection, hypertension, dialysis duration, catheter placement site, catheter duration, number of catheterizations, catheter type, CD4+ cells, albumin, C-reactive protein, hemoglobin, procalcitonin, inadequate hand hygiene, and APACHE II scores significantly influence the incidence of catheter-associated bloodstream infection in hemodialysis patients. Here, CD4 is linked to kidney disorder.
