Prevalence and Prognosis of Coexisting Frailty and Cognitive Impairment in Patients on Continuous Ambulatory Peritoneal Dialysis.

ABSTRACT: The aim of this study was to investigate the prevalence of coexisting frailty and cognitive impairment and its association with clinical outcomes in patients on continuous ambulatory peritoneal dialysis (CAPD). Patients on CAPD started to enroll from 2014 to 2016 and ended follow-up by 2017. Frailty was assessed by clinical frailty scale (CFS), and cognitive function was assessed by Montreal Cognitive Assessment (MoCA). Totally 784 CAPD patients were recruited, with median duration of PD 30.7 (8.9~54.3) months. The mean age was 48.8 ± 14.6 years, 320 (40.8%) patients were female and 130 (16.6%) had diabetic nephropathy. Patients with cognitive impairment were more than those with frailty (55.5% vs. 27.6%). Coexisting frailty and cognitive impairment was present in 23.9% patients. Pathway analysis showed that CFS score was negatively associated with MoCA score (β = -0.69, P < 0.001). Coexisting frailty and cognitive impairment was associated with decreased patient survival rate (Log-rank = 84.33, P < 0.001) and increased peritonitis rate (0.22 vs. 0.11, 0.15 and 0.12 episodes per patient year, respectively; all P < 0.001). It was concluded that there was a relatively high prevalence of coexisting frailty and cognitive impairment among patients on CAPD. Frailty was positively associated with cognitive impairment. Coexisting frailty and cognitive impairment increased the risk of adverse outcomes.

Project description:The prevalence of moderate to severe cognitive impairment in hemodialysis patients is more than double the prevalence in the general population. This study describes cognitive impairment occurrence in a peritoneal dialysis cohort compared with a cohort without chronic kidney disease (CKD).Cross-sectional study.51 English-speaking peritoneal dialysis patients from 2 urban dialysis units compared with 338 hemodialysis patients from 16 urban dialysis units and 101 voluntary controls without CKD from urban general medicine clinics.45-minute battery of 9 validated neuropsychological tests (cognitive domains memory, executive function, and language).Mild, moderate, or severe cognitive impairment, classified according to a previously designed algorithm.Of the peritoneal dialysis cohort, 33.3% had no or mild, 35.3% had moderate, and 31.4% had severe cognitive impairment; corresponding values were 60.4%, 26.7%, and 12.9% of the non-CKD cohort and 26.6%, 36.4%, and 37.0% of the hemodialysis cohort. A logistic regression model including age, sex, race, education, hemoglobin level, diabetes, and stroke showed that only nonwhite race (P = 0.002) and low education (P = 0.002) were associated with moderate to severe cognitive impairment in the peritoneal dialysis cohort. Compared with hemodialysis patients, more peritoneal dialysis patients had moderate to severe memory impairment (58% vs 51%), but fewer had impaired executive function (one-third vs one-half). Peritoneal dialysis was associated with a more than 2.5-fold increased risk of moderate to severe global cognitive impairment compared with no CKD (OR, 2.58; 95% CI, 1.02-6.53), as was hemodialysis (OR, 3.16; 95% CI, 1.91-5.24), in an adjusted logistic regression model.Small sample size, participation rate somewhat low.Similar to hemodialysis patients, two-thirds of peritoneal dialysis patients had moderate to severe cognitive impairment, enough to interfere with safely self-administering dialysis and adhering to complex medication regimens. These patients could benefit from cognitive assessment before and periodically after dialysis therapy initiation.

Project description:IntroductionThe impact of peritoneal dialysis modality on patient survival and peritonitis rates is not fully understood, and no large-scale randomized clinical trial (RCT) is available. In the absence of a RCT, the use of an advanced matching procedure to reduce selection bias in large cohort studies may be the best approach. The aim of this study is to compare automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD) according to peritonitis risk, technique failure and patient survival in a large nation-wide PD cohort.MethodsThis is a prospective cohort study that included all incident PD patients with at least 90 days of PD recruited in the BRAZPD study. All patients who were treated exclusively with either APD or CAPD were matched for 15 different covariates using a propensity score calculated with the nearest neighbor method. Clinical outcomes analyzed were overall mortality, technique failure and time to first peritonitis. For all analysis we also adjusted the curves for the presence of competing risks with the Fine and Gray analysis.ResultsAfter the matching procedure, 2,890 patients were included in the analysis (1,445 in each group). Baseline characteristics were similar for all covariates including: age, diabetes, BMI, Center-experience, coronary artery disease, cancer, literacy, hypertension, race, previous HD, gender, pre-dialysis care, family income, peripheral artery disease and year of starting PD. Mortality rate was higher in CAPD patients (SHR1.44 CI95%1.21-1.71) compared to APD, but no difference was observed for technique failure (SHR0.83 CI95%0.69-1.02) nor for time till the first peritonitis episode (SHR0.96 CI95%0.93-1.11).ConclusionIn the first large PD cohort study with groups balanced for several covariates using propensity score matching, PD modality was not associated with differences in neither time to first peritonitis nor in technique failure. Nevertheless, patient survival was significantly better in APD patients.
