According to the CDC, what is the most common factor contributing to bacterial infections in dialysis patients?

The correct answer highlights that the use of catheters for hemodialysis is a significant factor contributing to bacterial infections in dialysis patients. Catheters provide a potential entry point for bacteria into the bloodstream, which can lead to serious infections such as catheter-related bloodstream infections (CRBSIs). The nature of these devices, especially when they are left in place for extended periods, increases the risk of biofilm formation, where bacteria can adhere to the catheter's surface and become resistant to treatment.

The risk associated with catheter use is particularly heightened in populations undergoing hemodialysis, where the need for vascular access is crucial. Healthcare facilities implement strict protocols to manage catheter care and reduce infection rates since prevention of such infections is vital for patient safety and overall outcomes.

Other factors, while potentially contributing to infections, do not rank as the primary concern when considering the context of dialysis. Hand hygiene practices, for instance, though critical, are often emphasized as a means of prevention rather than a direct cause. Contaminated water and poor dietary habits also play a role in the general health of patients, but their impact on bacterial infections in the context of dialysis is not as immediate or significant as the risks posed by catheter use. Therefore, emphasizing catheter care and management
