Determinants Of Switching From Peritoneal To Hemodialysis In Preserving Residual Renal Function, Mohamed Katerji Jan 2017

Determinants Of Switching From Peritoneal To Hemodialysis In Preserving Residual Renal Function, Mohamed Katerji

Walden Dissertations and Doctoral Studies

There are more than 2 million end stage renal disease (ESRD) patients in the world. ESRD is becoming more manageable with the advent of competent therapies such as peritoneal dialysis (PD) and hemodialysis (HD). While recent evidence suggests that switching from PD to HD may preserve residual renal function longer than either PD or HD alone as an alternative approach, little is known about the optimal timing and the long-term efficacy of switching dialysis modes. The purpose of this quantitative retrospective study, based on the bio-psychosocial model, was to investigate the optimal timing and determinants of the effectiveness of switching …
