Motivators for and Barriers to Exercise Rehabilitation in Hemodialysis Centers: A Multicenter Cross-Sectional Survey.

OBJECTIVES: The aim of the study was to explore motivators for and barriers to exercise rehabilitation in hemodialysis patients and the barriers perceived by the hemodialysis center staff. DESIGN: A cross-sectional study was performed in five hemodialysis centers using patient questionnaires designed for this study to evaluate the motivators for and barriers to exercise rehabilitation. Questionnaires were not yet validated. RESULTS: Of the 471 recruited patients, 63.3% were willing to participant in exercise rehabilitation. The greatest motivators included improving quality of life (98.0%) and wanting to be healthier (98.0%). Perceived barriers included discomfort (59.0%), concerns regarding safety (36.7%), and disinterest (27.0%). Among these, unwillingness, disinterest, and having peripheral arterial disease were independent risk factors of lack of participation in exercise rehabilitation. The most common perceived barriers among the 90 employees that participated were lack of professional guidance and advice from rehabilitation therapists (93.1%), lack of exercise rehabilitation knowledge (86.2%), and lack of special exercise equipment (86.2%). CONCLUSIONS: Most patients were willing to exercise to improve their health and quality of life. Barriers to exercise rehabilitation included patient and staff factors. It is essential to establish a rehabilitation team within dialysis centers, including general staff and rehabilitation therapists. These centers require improved rehabilitation policies and access to specialized rehabilitation equipment.

When to initiate renal replacement therapy: The trend of dialysis initiation.

The timing of renal replacement therapy for patients with end-stage renal disease has been subject to considerable variation. The United States Renal Data System shows an ascending trend of early dialysis initiation until 2010, at which point it decreased slightly for the following 2 years. In the 1990s, nephrologists believed that early initiation of dialysis could improve patient survival. Based on the Canadian-United States Peritoneal Dialysis study, the National Kidney Foundation Dialysis Outcomes Quality Initiative recommended that dialysis should be initiated early. Since 2001, several observational studies and 1 randomized controlled trial have found no beneficial effect when patients were placed on dialysis early. In contrast, they found that an increase in mortality was associated with early dialysis initiation. The most recent dialysis initiation guidelines recommend that dialysis should be initiated at an estimated glomerular filtration rate (eGFR) of greater than or equal to 6 mL/min per 1.73 m(2). Nevertheless, the decision to start dialysis is mainly based on a predefined eGFR value, and no convincing evidence has demonstrated that patients would benefit from early dialysis initiation as indicated by the eGFR. Even today, the optimal dialysis initiation time remains unknown. The decision of when to start dialysis should be based on careful clinical evaluation.
