Contemplating Catheter Induced Blood Stream Infections and Associated Risk Factors in Diverse Clinical Settings: A Comprehensive Review

Abstract

Catheter-Related Bloodstream Infections (CRBSIs) are severe healthcare-associated complication that occurs when bacteria enter the bloodstream through a catheter. The risk of CRBSIs is influenced by various factors. Prolonged catheter placement increases the risk, as each day increases the potential for bacterial colonization and bloodstream infection. Proper aseptic technique and a sterile environment during catheter insertion are essential to minimize infection risk. Stringent infection control measures during insertion, including sterile gloves, thorough hand hygiene, and appropriate skin disinfection, are crucial. Inadequate catheter site care and suboptimal catheter management can contribute to CRBSIs. Regular cleaning, disinfection, and dressing changes are necessary to reduce the risk of infection. The type of catheter used also affects infection risk. Central Venous Catheters (CVCs) and arterial catheters, especially those inserted into the jugular or subclavian vein, carry a higher risk of CRBSIs compared to peripheral venous catheters. Individuals with compromised immune systems, such as chemotherapy patients, organ transplant recipients, and those with HIV/AIDS, are more susceptible to CRBSIs. Patients with existing infections, like pneumonia or urinary tract infections, are at a heightened risk of acquiring CRBSIs due to potential cross-contamination. Healthcare professionals who fail to practice thorough hand hygiene before and after catheter-related procedures can introduce pathogens into the bloodstream. Leaving catheters in place when no longer necessary or using them unnecessarily elevates the risk of infection. To prevent CRBSIs, strict infection control protocols, including effective hand hygiene, sterile catheter insertion techniques, routine site care, and prompt catheter removal when no longer needed, are imperative. Healthcare facilities often implement specific protocols to mitigate CRBSI risk and enhance patient safety.
