APD has been several advantages over CAPD such as reduced incidence of peritonitis, mechanical complications and greater psychosocial acceptability. Many studies demonstrated a benefit for APD. In one Mexican retrospective study, APD has a better technical survival than CAPD with improvement of 1st peritonitis episode and French registry data showed the better peritonitis-free probability and autonomy in APD compared to CAPD. One study found that peritonitis rates and hospitalization were significantly less in patients on APD when results were expressed as episode/patient-year. Also a small randomized clinical trial comparing APD and CAPD showed that APD can help to keep selected patients vocationally or socially active.
