The use of central venous catheters is a significant risk factor for infection in dialysis patients. These catheters provide a direct pathway for bacteria and other pathogens to enter the bloodstream, which can lead to serious infections, including bloodstream infections. Since dialysis involves accessing the vascular system regularly for treatment, any device that breaches the skin barrier increases the potential for infection.

In contrast, while frequent exercise and activity can promote overall health and well-being, they do not directly contribute to an increased risk of infection in the context of dialysis. Low calcium levels in the blood, while relevant for other health concerns, do not specifically heighten infection risk. Similarly, a high dietary protein intake is related to nutritional management but does not have a direct correlation with increased infection susceptibility in dialysis patients.
