Background: The elderly patients are the fastest-growing end-stage renal disease (ESRD) population in Taiwan. Assisted peritoneal dialysis (PD) has been employed to overcome the barriers to PD. The aim of this retrospective, single-center study was to describe the status of assisted PD and the impact of type of assistance on peritonitis in elderly patients in Taiwan.
Methods: One hundred and two patients initiated PD at the age of 65 or older between 2000 and 2008; 79 episodes of peritonitis occurred during the follow-ups. The patients and episodes of peritonitis were divided into three groups based on the type of assistance: (1) self-care: patients performing dialysis independently, (2) family: patients whose dialysis was performed by family, (3) caregiver: patients whose dialysis was performed by a private caregiver. Patient characteristics and incidence, etiology and outcomes of peritonitis were compared.
Results: There were 26 (25.5%), 44 (43.1%), and 32 (31.4%) patients in the self-care, family, and caregiver groups, respectively. The overall peritonitis rate was 1/33 patient-months. Patients in the caregiver group were older and had more comorbidities than the self-care group. They had a trend of higher overall peritonitis rate (1/24 patient-months, P = 0.077) and fungal peritonitis rate (P = 0.060) compared to the self-care and family groups, but this was statistically non-significant.
Conclusions: Three-fourths of elderly PD patients in the present study required assistance from family members or private caregivers. Caregiver-assisted patients were significantly older and had more comorbidities. Also, a non-significant trend of higher peritonitis incidence was observed in these patients.
