What could be a primary concern for elderly patients on peritoneal dialysis?

A primary concern for elderly patients on peritoneal dialysis is the increased risk of infection. This population often has a compromised immune system, making them more susceptible to infections, particularly peritonitis, which can be a serious complication of peritoneal dialysis.

In this method of dialysis, a catheter is placed in the abdominal cavity, allowing a dialysate solution to exchange waste products from the blood through the peritoneal membrane. The presence of the catheter adds a risk factor; any break in sterile technique during exchanges or complications with the catheter can lead to infections.

Elderly patients may not only have diminished immune responses but also other comorbidities, such as diabetes, which can further increase their vulnerability to infections. Therefore, monitoring for signs of infection and educating patients and caregivers about proper technique and hygiene practices is crucial in managing their care effectively.
