Abstract
Background
Peritoneal dialysis (PD) exchange procedure is complex. Patients with cognitive impairment (CI) may require assistance. We studied the prevalence of CI among PD patients, its impact on PD-related peritonitis and the outcome of assisted PD.
Methods
Cantonese version of Mini-Mental State examination (CMMSE) was performed in 151 patients newly started on PD. Data on patient characteristics including demographics, co-morbidities, blood parameters, medications, and number of PD-related peritonitis in the first 6 months were collected.
Results
151 subjects were recruited. The age of studied patients was 60 ± 15.0 years, and 45 % were female. The prevalence of CI was 13.9 % using education-adjusted cut-off of CMMSE. Patients older than 65-year-old, female, and lower education level were independent risk factors for CI (OR 9.27 p = 0.001, OR 14.84 p = 0.005, and OR 6.10 p = 0.009, respectively). Age greater than 65-year old is an independent risk factor for PD-related peritonitis but CI was not. Patients requiring assisted PD were of older age (p < 0.001), lower CMMSE (p < 0.001), and scored higher for age-adjusted Charlson Co-morbidity index (p < 0.001). Compared with self-care PD patients, assisted PD patients did not have higher rates exit site infection (p = 0.30) but had a trend of higher PD peritonitis (p = 0.07).
Conclusion
CI is common among local PD patients. Overall, CI could not be identified as an independent risk factor for PD peritonitis. There is a higher prevalence of CI among assisted PD patients but helpers may not completely eliminate the risk of PD-related peritonitis.
