Abstract
Background and objectives Assisted peritoneal dialysis is a treatment option for individuals with barriers to self-care who wish to receive home dialysis, but previous research suggests that this treatment modality is associated with a higher rate of hospitalization. The objective of our study was to determine whether assisted peritoneal dialysis has a different rate of hospital days compared to in-center hemodialysis.
Design, setting, participants, & measurements We conducted a multicenter, retrospective cohort study by linking a quality assurance dataset to administrative health data in Ontario, Canada. Subjects were accrued between January 1, 2004 and July 9, 2013. Individuals were grouped into assisted peritoneal dialysis (family or home care assisted) or in-center hemodialysis on the basis of their first outpatient dialysis modality. Inverse probability of treatment weighting using a propensity score was used to create a sample in which the baseline covariates were well balanced.
Results The study included 872 patients in the in–center hemodialysis group and 203 patients in the assisted peritoneal dialysis group. Using an intention to treat approach, patients on assisted peritoneal dialysis had a similar hospitalization rate of 11.1 d/yr (95% confidence interval, 9.4 to 13.0) compared with 12.9 d/yr (95% confidence interval, 10.3 to 16.1) in the hemodialysis group (P=0.19). Patients on assisted peritoneal dialysis were more likely to be hospitalized for dialysis-related reasons (admitted for 2.4 d/yr [95% confidence interval, 1.8 to 3.2] compared with 1.6 d/yr [95% confidence interval, 1.1 to 2.3] in the hemodialysis group; P=0.04). This difference was partly explained by more hospital days because of peritonitis. Modality switching was associated with high rates of hospital days per year.
Conclusions Assisted peritoneal dialysis was associated with similar rates of all-cause hospitalization compared with in-center hemodialysis. Patients on assisted peritoneal dialysis who experienced peritonitis and technique failure had high rates of hospitalization.

I hope there wasn't a lot of money wasted on this study. The results should have been a fore-known conclusion. Biased from the concept. How can it be in any way possible to compare these two groups of people when the one group has "individuals with barriers to self-care". These people can NOT care for themselves, and must have assistance to set-up and complete PD Exchanges. You may as well be comparing people residing in 'assisted living' with people living in their own homes. There will be a substantial difference in the rate of hospitalizations between the two groups.
This study 'could' have had redeeming factors IF they had compared some of the reasons for hospitalizations, such as, renal related, dialysis related infection, etc.. But they didn't. At least not from the limited information shown.
Sometimes I swear, some Dr's have no common sense.
