What is an advantage of automated PD (CCPD) over manual PD (CAPD)?

• A. Increased daytime exchanges.
• B. Higher infection risk.
• C. No difference.
• D. Fewer daytime exchanges, more consistent dialysis dose, potential for better adherence and infection risk reduction.

Answer: (D)

Automated PD provides several practical advantages over manual PD. By using a cycler overnight, it reduces daytime exchanges, meaning you don’t have to perform multiple manual connections and bag changes during the day. This makes the daily routine simpler and frees up daytime activities.

The dialysis dose is more consistent because the cycler controls the sequence and dwell times automatically, delivering steady toxin clearance and fluid removal over the course of the night. That consistency helps maintain stable overall dialysis adequacy.

Adherence tends to improve as well, since the therapy is largely automated and less dependent on the patient’s daytime scheduling and manual technique. Fewer manual steps also reduces the chances of missed exchanges.

Infection risk can be lower with CCPD because there are fewer opportunities for contamination during daytime bag handling and connections, and the closed-circuit nature of the automated system minimizes handling errors.

So the best choice highlights fewer daytime exchanges, a more consistent dialysis dose, and potential improvements in adherence and infection risk reduction.
