Abstract
We conducted a multi-center cooperative prospective survey of the technique and patient survival focusing on Japanese PD patients older than 65 years.
Four-hundred ten PD patients from twenty-five PD centers, were enrolled in the survey (mean 75 years old, max : 92 years old), and factors influencing the outcome were determined using the Cox proportional hazards model adjusted for possible confounding factors at the baseline. Variables examined in this study were ; patients' clinical background such as age, body mass index(BMI), comobidity determined by Charlson's Comobidity Index(CCI), residual renal function, blood parameters, principal person who selected PD treatment, and persons who actually performed PD bag exchange.
The 50% technical and patient survivals were 30.3 and more than 48 months, respectively. Those factors such as CCI, patient intention to select PD, bag exchange by patients, in addition to BMI and positive CRP levels, were demonstrated to be independent factors for both outcomes.
Conclusion : Less comobidity, independent life, absence of poor nutrition and inflammation could be predictive factors for better patient outcomes in elderly Japanese PD patients.
